Decimal vs Double?

I'm new to C#, and I want to use a trackbar for the forms opacity This is my code decimal trans = trackBar1.Value / 5000 this.Opacity = trans When I try to build it, I get this error **Cannot implicitly convert type 'decimal' to 'double** I tried making trans a double, but then the control doesn't work. This code worked fine for me in VB.NET. Any suggestions?

Percentage width child in absolutely positioned parent doesn't work in IE7

I've got an absolutely positioned div containing several children, one of which is a relatively positioned div. When I use a percentage-based width on the child div, it collapses to zero width on IE7, but not on Firefox or Safari. If I use pixel width, it works. If the parent is relatively positioned, the percentage width on the child works. Is there something I'm missing here? Is there an easy fix besides the pixel-based width on the child? Is there an area of the CSS spec that covers this?

Reliable Timer in a Console Application

I am aware in dot net there are three timer types (see [http://msdn.microsoft.com/en-us/magazine/cc164015.aspx][1]). I have chosen a the threaded timer as the other types can drift if the main thread is busy and I need this to be reliable. The way this timer works in the control of the timer is put on another thread so it can always tick along with the work begin completed on the parent thread when it is not busy. The issue I have is that with this timer in a console application is that while the timer is ticking along on another thread the main thread is not doing anything so the app closes. I tried adding a while true loop but then the main thread is too busy when the timer does go off. Any ideas welcome. [1]: http://msdn.microsoft.com/en-us/magazine/cc164015.aspx

Fastest way to get value of pi

Solutions welcome in any language. :-) I'm looking for the fastest way to obtain the value of pi, as a personal challenge. More specifically I'm using ways that don't involve using #defined constants like M_PI, or hardcoding the number in. The program below tests the various ways I know of. The inline assembly version is, in theory, the fastest option, though clearly not portable; I've included it as a baseline to compare the other versions against. In my tests, with builtins, the `4 * atan(1)` version is fastest on GCC 4.2, because it auto-folds the `atan(1)` into a constant. With `-fno-builtin` specified, the `atan2(0, -1)` version is fastest. Here's the main testing program (`pitimes.c`): #include <math.h> #include <stdio.h> #include <time.h> #define ITERS 10000000 #define TESTWITH(x) { \ diff = 0.0; \ time1 = clock(); \ for (i = 0; i < ITERS; ++i) \ diff += (x) - M_PI; \ time2 = clock(); \ printf("%s\t=> %e, time => %f\n", #x, diff, diffclock(time2, time1)); \ } static inline double diffclock(clock_t time1, clock_t time0) { return (double) (time1 - time0) / CLOCKS_PER_SEC; } int main() { int i; clock_t time1, time2; double diff; /* Warmup. The atan2 case catches GCC's atan folding (which would * optimise the ``4 * atan(1) - M_PI'' to a no-op), if -fno-builtin * is not used. */ TESTWITH(4 * atan(1)) TESTWITH(4 * atan2(1, 1)) #if defined(__GNUC__) && (defined(__i386__) || defined(__amd64__)) extern double fldpi(); TESTWITH(fldpi()) #endif /* Actual tests start here. */ TESTWITH(atan2(0, -1)) TESTWITH(acos(-1)) TESTWITH(2 * asin(1)) TESTWITH(4 * atan2(1, 1)) TESTWITH(4 * atan(1)) return 0; } And the inline assembly stuff (`fldpi.c`), noting that it will only work for x86 and x64 systems: double fldpi() { double pi; asm("fldpi" : "=t" (pi)); return pi; } And a build script that builds all the configurations I'm testing (`build.sh`): #!/bin/sh gcc -O3 -Wall -c -m32 -o fldpi-32.o fldpi.c gcc -O3 -Wall -c -m64 -o fldpi-64.o fldpi.c gcc -O3 -Wall -ffast-math -m32 -o pitimes1-32 pitimes.c fldpi-32.o gcc -O3 -Wall -m32 -o pitimes2-32 pitimes.c fldpi-32.o -lm gcc -O3 -Wall -fno-builtin -m32 -o pitimes3-32 pitimes.c fldpi-32.o -lm gcc -O3 -Wall -ffast-math -m64 -o pitimes1-64 pitimes.c fldpi-64.o -lm gcc -O3 -Wall -m64 -o pitimes2-64 pitimes.c fldpi-64.o -lm gcc -O3 -Wall -fno-builtin -m64 -o pitimes3-64 pitimes.c fldpi-64.o -lm Apart from testing between various compiler flags (I've compared 32-bit against 64-bit too, because the optimisations are different), I've also tried switching the order of the tests around. `The atan2(0, -1)` version still comes out top every time, though. I'm keen to hear what results you have, as well as improvements to the testing process. :-)

Multiple submit buttons on a form

Let's say you create a Wizard in an HTML form. One button goes back and one goes forward. Since the "back" button appears first in the markup, when you press Enter it will use that button to submit the form. Ex: <form> <input type="text" name="field1" /> <!-- put your cursor in this field and press Enter --> <input type="submit" name="prev" value="Previous Page" /> <!-- This is the button that will submit --> <input type="submit" name="next" value="Next Page" /> <!-- But this is the button that I WANT to submit --> </form> What I would LIKE to do, is get to decide which button is used to submit the form when a user presses Enter. That way, when you press Enter the Wizard will move to the next page, not the previous. Do you have to use tabindex to do this?

How can you get Subclipse in Aptana to work with the newest release of Subversion?

The version of Subclipse (1.2.4) currently available through Aptana's automagic Plugins Manager does not work with the newest version of Subversion. I see on the Subclipse website however that they have 1.4.2 out for Eclipse. So I added a new remote update site: http://subclipse.tigris.org/update_1.4.x to my Update manager. When I tried to install it, it told me I needed Mylyn 3.0.0. So I after much searching I found Mylyn 3.0.0 and added another new remote update site: http://download.eclipse.org/tools/mylyn/update/e3.3 to my update manager. Then when I tried to install that, it told me I needed org.eclipse.ui 3.3.0 or equivalent. Looking at the configuration details for Aptana, it looks like it is built against eclipse 3.2.2. Does anyone know if there is a way to upgrade the version of Eclipse Aptana is built against to 3.3.0? Or if there is some other way to get Subclipse to work with the very newest version of Subversion? I know this isn't necessarily a "programming" question, but I hope it's ok since it's highly relevant to the programming experience...

I execute this in Air using the following method: public static function RunSqlFromFile(fileName:String):void { var file:File = File.applicationDirectory.resolvePath(fileName); var stream:FileStream = new FileStream(); stream.open(file, FileMode.READ) var strSql:String = stream.readUTFBytes(stream.bytesAvailable); NonQuery(strSql); } No errors are generated, however only tRole exists. It seems that it only looks at the first query (up to the semicolon- if I remove it, the query fails). Is there anyway to call multiple queries in one statement?

Flat File Databases in PHP

What are your best practices around creating flat file database structures in PHP? A lot of the more mature PHP flat file frameworks I see out there attempt to implement SQL-like query syntax, which is over the top for my purposes in most cases (I would just use a database at that point). Are there any elegant tricks out there to get good performance and features with the small code overhead one would want by taking on this problem in the first place?

Is gettimeofday() guaranteed to be of microsecond resolution?

So I find myself porting a game that was originally written for the Win32 API to Linux (well, porting the OS X port of the Win32 port to Linux), and have implemented QueryPerformanceCounter by giving the uSeconds since the process start up: BOOL QueryPerformanceCounter(LARGE_INTEGER* performanceCount) { gettimeofday(&currentTimeVal, NULL); performanceCount->QuadPart = (currentTimeVal.tv_sec - startTimeVal.tv_sec); performanceCount->QuadPart *= (1000 * 1000); performanceCount->QuadPart += (currentTimeVal.tv_usec - startTimeVal.tv_usec); return true; } This, coupled with QueryPerformanceFrequency() giving a constant 1000000 as the frequency works well **on my machine**, giving me a 64 bit variable that contains uSeconds since the program's start up. So _is this portable?_ I don't want to discover it works differently if the kernel was compiled in a certain way or anything like that. I am fine with it being non-portable to something other than Linux, however.

What are the effects? - How to prevent? - If your application has memory leak, does it go away when the process exits or killed? Or do memory leaks in your application affects other processes on the system even after process completion? - And what about unmanaged code accessed via COM Interop and/or P/Invoke?

Best Subversion clients for Windows Vista (64bit)

I've been using [TortoiseSVN ][1] in a Windows environment for quite some time. It seems very feature-complete and nicely integrated into the Windows shell, and more importantly, it's fairly painless to teach to colleagues with little or no experience with source control. **However**, since we have moved to Windows Vista 64bit, Tortoise has been very buggy and has seemed to cause lots of explorer.exe abnormalities and crashes. This has happened both with older versions of the software and the latest version (1.5.1 build 13563). I was curious if anyone has suggestions for other Subversion clients that will run on Windows (specifically Vista 64bit). Developers here use a variety of text editors so using Visual Studio or Dreamweaver for SVN is not ideal. I have heard great things about [Cornerstone][2], and would love something similar for Windows if it exists. [1]: http://tortoisesvn.tigris.org/ [2]: http://www.zennaware.com/cornerstone/

Decoding T-SQL CAST in C#/VB.net

Greetings all, Recently our site has been deluged with the resurgence of the ASPRox bot SQL Injection attack. Without going into details, the attack attempts to execute SQL code by encoding the T-SQL commands in an ASCII encoded BINARY string. It looks something like this: > DECLARE%20@S%20NVARCHAR(4000);SET%20@S=CAST(0x44004500...06F007200%20AS%20NVARCHAR(4000));EXEC(@S);-- I was able to decode this in SQL, but I was a little wary of doing this since I didn't know exactly what was happening at the time. I tried to write a simple decode tool so I could decode this type of text without even touching SQL server. The main part I need decoded is: > CAST(0x44004500...06F007200 AS > NVARCHAR(4000)) I've tried all of the following commands with no luck: txtDecodedText.Text = System.Web.HttpUtility.UrlDecode(txtURLText.Text); txtDecodedText.Text = Encoding.ASCII.GetString(Encoding.ASCII.GetBytes(txtURLText.Text)); txtDecodedText.Text = Encoding.Unicode.GetString(Encoding.Unicode.GetBytes(txtURLText.Text)); txtDecodedText.Text = Encoding.ASCII.GetString(Encoding.Unicode.GetBytes(txtURLText.Text)); txtDecodedText.Text = Encoding.Unicode.GetString(Convert.FromBase64String(txtURLText.Text)); Can anybody suggest the proper way to translate this encoding without using SQL Server. Is is possible? I'll take VB.net code since I'm familiar with that too.

I know that from outside of the object you should use a getter/setter, but from within would you just do: Java: String property = this.property; PHP: $property = $this->property; or would you do: Java: String property = this.getProperty(); PHP: $property = $this->getProperty(); Forgive me if my Java is a little off, it's been a year since I programmed in Java...

How to export data from SQL Server to MySQL

I've been banging my head against SQL Server 2005 trying to get a lot of data out. I've been given a database with newarly 300 tables in it and I need to turn this into a MySQL database. My first call was to use bcp but unfortunately it doesn't produce valid CSV - strings aren't encapsulated so you can't deal with any row that has a string with a comma in it (or whatever you use as a delimiter) and I would still have to hand write all of the create table statements as obviously CSV doesn't tell you anything about the data types. What would be better is if there was some tool that could connect to both SQL Server and MySQL and then do a copy. You lose views, stored procedures, trigger, etc. but it isn't hard to copy a table that only uses base types from one DB to another... is it? Does anybody know of such a tool? I don't mind how many assumptions it makes or what simplifications occur, as long as it supports integer, float, datetime and string. I have to do a lot of pruning, normalising, etc. anyway so I don't care about keeping keys, relationships or anything like that but I need the initial set of data in fast!

XSD DataSets and ignoring foreign keys

I have and pretty standard table setup in a current application using the .net XSD DataSet and TableAdapter features. My contracts table consists of some standard contract information, with a column for the primary department. This column is a foreign key to my Departments table, where I store the basic department name, id, notes. This is all setup and functioning in my SQL Server. When I use the XSD tool, I can drag both tables in at once and it auto detects/creates the foreign key I have between these two tables. This works great when I'm on my main page and am viewing contract data. However, when I go to my administrative page to modify the department data. I typically do something like this: Dim dtDepartment As New DepartmentDataTable() Dim taDepartment As New DepartmentTableAdapter() taDepartment.Fill(dtDepartment) However, at this point an exception is thrown saying to the effect that there is a foreign key reference broken here, I'm guessing since I don't have the Contract DataTable filled. Has anybody encountered this before? I know I can simply remove the foreign key from the XSD to make things work fine, but having the additional integrity check there and having the XSD schema match the SQL schema in the database is nice.

Printing HTML

I want to print HTML from a C# web service. The Web Browser control is overkill, and does not function well in a service-environment, nor does it function well on a system with very tight security constraints. Is there any sort of free .NET library that will support the printing of a basic HTMl page? Here is the code I have so far, that is not running properly. public void PrintThing(string document) { if (Thread.CurrentThread.GetApartmentState() != ApartmentState.STA) { Thread thread = new Thread((ThreadStart) delegate { PrintDocument(document); }); thread.SetApartmentState(ApartmentState.STA); thread.Start(); } else { PrintDocument(document); } } protected void PrintDocument(string document) { WebBrowser browser = new WebBrowser(); browser.DocumentText = document; while (browser.ReadyState != WebBrowserReadyState.Complete) { Application.DoEvents(); } browser.Print(); } This works fine when called from UI-type threads, but nothing happens when called from a service-type thread. Changing Print() to ShowPrintPreviewDialog() yields the following IE script error: Error: 'dialogArguments.___IE_PrintType' is null or not an object URL: res://ieframe.dll/preview.dlg And a small empty print preview dialog appears.

Floating Point Number parsing: Is there a Catch All algorithm?

One of the fun parts of multi-cultural programming are numbers formats. Americans use 10,000.50, Germans use 10.000,50, French use 10 000,50 etc. My first approach would be: Take the string, parse it backwards, until I encounter a separator and use this as my decimal separator. The obvious flaw with that: 10.000 would be interpreted as 10. Another approach: if the string contains 2 different non-numeric characters, use the last one as the decimal separator and discard the others. If I only have one, check if it occurs more than once and discard it if it does. It it only appears once, check if it has 3 digits after it. If yes, discard it, otherwise use it as decimal separator. The obvious "best solution" would be to detect the User's culture or Browser, but that does not work if you have a Frenchman an an en-US Windows/Browser. I just wonder: does the .net Framework contain some mythical black magic floating point parser that is better than Double.(Try)Parse() in trying to auto-detect the number format?

Yes, I know. The existence of a running copy of SQL Server 6.5 in 2008 is absurd. That stipulated, what is the best way to migrate from 6.5 to 2005? Is there any direct path? Most of the documentation I've found deals with upgrading 6.5 to 7. Should I forget about the native SQL Server upgrade utilities, script out all of the objects and data, and try to recreate from scratch? I'm going to attempt the upgrade this weekend. Any advice would be welcomed.

Register Windows program with the mailto protocol programmatically

How do I make it so mailto: links will be registered with my program? And then how would I handle that event in my program? I'm using Delphi 7 (Win32 program), but you can assume I'm using C/C++ if it makes it easier to answer. Just a non-.NET answer. Most of the solutions I found from a quick Google search are how to do this manually, but I need to do this automatically for users of my program if they click a button such as "set as default email client".

SQL Server 2005 implementation of MySQL REPLACE INTO?

MySQL has this incredibly useful yet properitary REPLACE INTO SQL Command. I wonder: Can this easily be emulated in SQL Server 2005? Starting a new Transaction, doing a Select() and then either UPDATE or INSERT and Commit is always a little bit a pain in the a.., especially when doing it in the application and therefore always keeping 2 versions of the statement. I wonder if there is an easy and **universal** way to implement such a function into SQL Server 2005?

Adding Scripting functionality to .net Apps

I have a little game written in C#. It uses a database as backend. It's a Trading Card Game, and I wanted to implement the function of the cards as Script. What I mean is that I essentially have an Interface ICard which the Card implements (public class Card056 : ICard) and which contains function that are called by the game. Now, to make the thing maintainable/moddable, I would like to have the Class for each card as source code in the database and essentially compile it on first use. So when I have to add/change a card, I'll just add it to the database and tell my app to refresh, without needing any Assembly-Deployment (especially since we would be talking about 1 assembly per card which means hundreds of assemblies). Does anyone know if that is possible? Register a class from a source file and then instantiate it etc. ICard Cards[current] = new MyGame.CardLibrary.Card056(); Cards[current].OnEnterPlay(currentGame); The language is C#, but extra Bonus if it's possible to write the script in any .net language.

GTK implementation of MessageBox

I have been trying to implement Win32's MessageBox using GTK. The app using SDL/OpenGL, so this isn't a GTK app. I handle the initialisation (**gtk_init**) sort of stuff inside the MessageBox function as follows: int MessageBox(HWND hwnd, const char* text, const char* caption, UINT type) { GtkWidget *window = NULL; GtkWidget *dialog = NULL; gtk_init(&gtkArgc, &gtkArgv); window = gtk_window_new(GTK_WINDOW_TOPLEVEL); g_signal_connect(G_OBJECT(window), "delete_event", G_CALLBACK(delete_event), NULL); g_signal_connect(G_OBJECT(window), "destroy", G_CALLBACK(destroy), NULL); // gcallback calls gtk_main_quit() gtk_init_add((GtkFunction)gcallback, NULL); if (type & MB_YESNO) { dialog = gtk_message_dialog_new(GTK_WINDOW(window), GTK_DIALOG_DESTROY_WITH_PARENT, GTK_MESSAGE_QUESTION, GTK_BUTTONS_YES_NO, text); } else { dialog = gtk_message_dialog_new(GTK_WINDOW(window), GTK_DIALOG_DESTROY_WITH_PARENT, GTK_MESSAGE_INFO, GTK_BUTTONS_OK, text); } gtk_window_set_title(GTK_WINDOW(dialog), caption); gint result = gtk_dialog_run(GTK_DIALOG(dialog)); gtk_main(); gtk_widget_destroy(dialog); if (type & MB_YESNO) { switch (result) { default: case GTK_RESPONSE_DELETE_EVENT: case GTK_RESPONSE_NO: return IDNO; break; case GTK_RESPONSE_YES: return IDYES; break; } } return IDOK; } Now, I am by no means an experienced GTK programmer, and I realise that I'm probably doing something(s) horribly wrong. However, my problem is that the last dialog popped up with this function stays around until the process exits. Any ideas?

This isn't a question, just more seeking expert advice. What's the optimal level of concurrency that the C++ implementation of BerkeleyDB can reasonably support? How many threads can I have hammering away at the DB before throughput starts to suffer because of resource contention? I've read the manual and know how to set the number of locks, lockers, database page size, etc., but I'd just like some advice from someone who has real-world experience with BDB concurrency. My application is pretty simple, I'll be doing gets and puts of records that are about 1kb each. No cursors, no deleting.

Best Practice: Collaborative Environment, Bin Directory, SVN

What are the best practices for checking in BIN directories in a collaborative development environment using SVN? Should project level references be excluded from checkin?

ASP.net, Visual Studio and Subversion - how to integrate?

I use AnkhSVN and Visual Studio 2005 and 2008. Now, one thing that bugs me is that Ankh does not really work with ASP.net sites - I cannot add them properly to a repository and it won't detect changes, **especially** because the site is on a remote server accessed through Frontpage Extensions (File => Open Site). Now, I wonder what alternatives there are? Does anyone know a better plugin? Manually downloading the files through FTP and using TortoiseSVN or svn.exe is not really the level of integration I want :) I want to stay within the VS IDE when possible. Also, I do not control the remote Server, so I can not install anything on it, which means the whole change tracking/comparison to repository has to be done on my machine.

Is there a version control system for database structure changes?

I often run into the following problem. I work on some changes to a project that require new tables or columns in the database. I make the database modifications and continue my work. Usually, I remember to write down the changes so that they can be replicated on the live system. However, I don't always remember what I've changed and I don't always remember to write it down. So, I make a push to the live system and get a big, obvious error that there is no NewColumnX. Ugh. Regardless of the fact that this may not be the best practice for this situation, is there a version control system for databases? I don't care about the specific database technology. I just want to know if one exists. If it happens to work with MS SQL Server, then great.

I know Java doesn't have unsigned values, and that must have been a concious decision on Sun's part. Looking forward to hearing everybody's opinion.

But lately some of the emails i send out programmatically have started being shuffled into people's spam folder automatically -- and i'm wondering what i can do about it. This is despite the fact that these particular emails are not ones that humans would mark as spam (specifically, they are emails that contain license keys that people have paid good money for, so i don't think they're going to consider them spam) I figure this is a big topic in which i am essentially an ignorant simpleton.

How to switch a large app from VB6 to VB .net

My company makes a monolithic piece of software that our customers use to run their car dealerships. The original app was written in VB6, and it has grown substantially over the last few years. Until now, there hasn't really been a business case for switching to the .net framework. Sure, it's newer, considerably better at certain things, and when used correctly speeds development time, but there's nothing we can't do in VB6 that we need to be able to do. Getting things done is harder in VB6, but almost nothing is impossible. Recently though, Microsoft dropped support for VB6, and it seems obvious to me that switching to a new platform is inevitable. The way VB .net works and requires you to think is so fundamentally different (heck, even the way you pass variables into subs has changed), and as far as I can tell, switching to .net would require a complete re-design and re-write of the app. My question(s): Have any of you been in this position? Of the tools available to smooth the transition, which ones work and which should be avoided? And how do I sell our customers and my boss on this? As the suits like to say, where's the ROI?

Tool to aid Code Review..

For our small team of 20 developers, we used do code review like: 1. Make a label in svn and publish the label to the reviewers 2. Reviewers checkout the code and add comments in line (with marker like: // REVIEWER_NAME::REVIEW COMMENT:) 3. After all comments are in, reviewer checks in the code, preferably with new label. 4. Developer checks the comments and makes changes (if appropriate) 5. Developer keeps an excel sheet report for considered changes and reasons for ignored comments Problem: Developer needs to keep track of multiple labels which might have same comments Sometimes we even do One on One review and if we really have time, even do Table review (team of reviewers looks at the code on projector, on the fly, and pass comment) I was wondering: Are you guys using any specific tool which helps to do code reviews smoother? I have heard of Code collaborator. But have anyone used that? Is it worth the money?

Tool to aid Code Review.. === For our small team of 20 developers, we used do code review like: 1. Make a label in svn and publish the label to the reviewers 2. Reviewers checkout the code and add comments in line (with marker like: // REVIEWER_NAME::REVIEW COMMENT:) 3. After all comments are in, reviewer checks in the code, preferably with new label. 4. Developer checks the comments and makes changes (if appropriate) 5. Developer keeps an excel sheet report for considered changes and reasons for ignored comments Problem: Developer needs to keep track of multiple labels which might have same comments Sometimes we even do One on One review and if we really have time, even do Table review (team of reviewers looks at the code on projector, on the fly, and pass comment) I was wondering: Are you guys using any specific tool which helps to do code reviews smoother? I have heard of Code collaborator. But have anyone used that? Is it worth the money?

Decode email address from Gravatar..

I suppose, Gravatar generates the image from email address. If so, the reverse should be possible. How difficult would be to get the email associated with the image? Isnt it a potential spam threat? What are your thoughts? (other than calling me paranoid ;) i did that already)

Unload a COM control when working in VB6 IDE

Part of my everyday work is maintaining and extending legacy VB6 applications. A common engire is written in C/C++ and VB6 uses these functions in order to improve performance. When it comes to asynchronous programming, a C interface is not enough and we rely on COM controls to fire events to VB6. My problem is that when I say in VB6 that I want to use a registered contorl, VB load this control in memory and does not unload it until I quit the VB6 IDE. As the control is loaded the whole time, I am unable to recompile it in VC6, because the DLL file is locked. A solution I found is not to enable the control in VB but use the CreateObject() with the full name of my control. The problem then is that I must declare my control as an Object because VB6 knows nothing of the interface I am using and I do not have access to IntelliSense, which is a pain. Any idea how I can tell VB6 to unload controls after quitting the application ? or directly in the IDE ? Thanks

How do you schedule tasks in Windows?

I run into a situation every couple of months where I need to develop a solution that's scheduled to run periodically, but I haven't found a way to handle this in Windows that I'm entirely happy with. Every time I do it, I end up feeling corralled into using a Windows Service, which seems to be an unacceptable amount of overhead for something I could do with a cron job in Unix. Am I missing something here? What have you used to schedule an application in Windows?

Implementation of "Remember me" in a Rails application.

My Rails-app has a sign in box with a "remember me" checkbox. Users who check that box should remain logged in even after closing their browser. I'm keeping track of whether users are logged in by storing their id in the user's session. But sessions are implemented in Rails as session cookies, which are not persistent. I can _make_ them persistent: class ApplicationController < ActionController::Base before_filter :update_session_expiration_date private def update_session_expiration_date options = ActionController::Base.session_options unless options[:session_expires] options[:session_expires] = 1.year.from_now end end end But that seems like a hack, which is surprising for such common functionality. Is there a better way?

WinForms ComboBox data binding gotcha

Ok, I'm a web developer, but I find myself dabbling in windows forms projects every now and then. One thing that confounds me to this day is the following. Assume you are doing something like the following List<string> myitems = new List<string> { "Item 1", "Item 2", "Item 3" }; ComboBox box = new ComboBox(); box.DataSource = myitems; ComboBox box2 = new ComboBox(); box.DataSource = myitems So now we have 2 combo boxes bound to that array, and everything works fine. But when you change the value of one combo box, it changes BOTH combo boxes to the one you just selected. Now, I know that Arrays are always passed by reference (learned that when i learned C :D), but why on earth would the combo boxes change together? I don't believe the combo box control is modifying the collection at all. As a work around, don't this would achieve the funcionality that is expected / desired ComboBox box = new ComboBox(); box.DataSource = myitems.ToArray();

Continuous Integration System for a Python Codebase

I'm starting work on a hobby project with a python codebase and would like to set up some form of continuous integration (i.e. running a battery of test-cases each time a check-in is made and sending nag e-mails to responsible persons when the tests fail) similar to CruiseControl or TeamCity. I realize I could do this with hooks in most VCSes, but that requires that the tests run on the same machine as the version control server, which isn't as elegant as I would like. Does anyone have any suggestions for a small, user-friendly, open-source continuous integration system suitable for a Python codebase?

Deploying SQL Server Databases from Test to Live

I wonder how you guys manage deployment of a database between 2 SQL Servers, specifically SQL Server 2005. Now, there is a development and a live one. As this should be part of a buildscript (standard windows batch, even do with current complexity of those scripts, i might switch to PowerShell or so later), Enterprise Manager/Management Studio Express do not count. Would you just copy the .mdf File and attach it? I am always a bit careful when working with binary data, as this seems to be a compatiblity issue (even though development and live should run the same version of the server at all time). Or - given the lack of "EXPLAIN CREATE TABLE" in T-SQL - do you do something that exports an existing database into SQL-Scripts which you can run on the target server? If yes, is there a tool that can automatically dump a given Database into SQL Queries and that runs off the command line? (Again, Enterprise Manager/Management Studio Express do not count). And lastly - given the fact that the live database already contains data, the deployment may not involve creating all tables but rather checking the difference in structure and ALTER TABLE the live ones instead, which may also need data verification/conversion when existing fields change. Now, i hear a lot of great stuff about the [Red Gate][1] products, but for hobby projects, the price is a bit steep.

Best way to access Exchange using PHP

I'm writing a CMS application in PHP and one of the requirements is that it must be able to interface with the customer's exchange server. I've written up this functionality a few times before and have always used WebDAV to do it, but now I'm leaning away from that. I will be running the site on IIS OR Apache (no preference) on Windows server 2008. A few things I would need to do include adding contacts to a given user's address book, sending emails AS a given user and running reports on contacts for a user. All of this is pretty easy to do with WebDAV, but if there is a better way that doesn't require any functionality that is likely to be deprecated any time soon. Any ideas?

Robust Random Number Generation in C++/C#

I'm looking for a performant, reasonably robust RNG using no special hardware. It can use mathematical methods (Mersenne Twister, etc), it can "collect entropy" from the machine, whatever. On Linux/etc we have a drand48() which generates 48 random bits. I'd like a similar function/class for C++ or C# which can generate more than 32 bits of randomness and which low-order bits are equally as random as high-order bits. It doesn't have to be cryptographically secure but it must not use or be based on the C-language rand() or .NET System.Random. Any source code, links to source, etc. would be appreciated! Failing that, what TYPE of RNG should I be looking for? Thanks!

I've had conversations with friends about how annoying _XYZ API_ was to deal with and how someone could build a better one, and I was curious what other's thoughts were on the subject. Is there a good and straightforward way to implement a GUI from the programmer's standpoint, and has someone done it yet?

Most efficient code for the first 10000 prime numbers?

I want to print the first 10000 prime numbers. Can anyone give me the most efficient code for this? Clarifications: 1. It does not matter if your code is inefficient for n >10000. 2. The size of the code does not matter. 3. You cannot just hard code the values in any manner.

When to use lambda, when to use Proc.new?

In Ruby 1.8, there are subtle differences between proc/lambda on the one hand, and Proc.new on the other. - What are those differences? - Can you give guidelines on how to decide which one to choose? - In Ruby 1.9, proc and lambda are different. What's the deal?

Swap unique indexed column values in database.

I have a database table and one of the fields (not primary key) is having unique index on it. Now I want to swap values under this column for two rows. How could this be done? Two hack I know are: 1. Delete both rows and re-insert them 2. Update rows with some other value and swap and then update to actual value. But I don't want to go for these as they do not seem to be the appropriate solution to the problem. Could anyone help me out?

Automatically update version number

I would like the version property of my application to be incremented for each build but I'm not sure on how to enable this functionality in Visual Studio (2005/2008). I have tried to specify the AssemblyVersion as 1.0.* but it doesn't get me exactly what I want. I'm also using a settings file and in earlier attempts when the assembly version changed my settings got reset to the default since the application looked for the settings file in another directory. I would like to be able to display a version number in the form of 1.1.38 so when a user finds a problem I can log the version they are using as well as tell them to upgrade if they have an old release.

Checklist for IIS 6 / ASP.NET Windows Authentication?

I've been having trouble getting my ASP.NET application to automatically log users into the Intranet site I'm building. No matter the googling or the experimentation I applied, there is always a login box displayed by IE7. I've got Windows authentication mode set in the Web.config, disabled anonymous access and configured the correct default domain in IIS, but it's still asking the user to log in and, more annoyingly, the user is required to provide the domain too (*DOMAIN\auser*), which is causing problems with non-technical visitors. Thank Zeus for password remembering functionality. I'm not the network administrator so it's possible that something about Active Directory is set up incorrectly, or it could just be me missing something very simple. Please note that I don't want to impersonate the user, I just need to know that the IPrincipal.Name property matches that of a valid record in my user database, hence authenticating the user to my application. To this end, it would be very useful to have a checklist of all configuration requirements for AD, ASP.NET and IIS to work together in this manner as a reference for debugging and hopefully reducing some user friction. Thanks for your help.

Encrypting Passwords

What is the fastest, yet secure way to encrypt passwords in PHP, and for which ever method you choose is it portable?<br />In other words if I later migrate my website to a different server will my passwords continue to work?<br />The method I am using now I was told is dependent on the exact versions of the libraries installed on the server.

What level of programming should I have to contribute to open source?

I'd like to contribute to open source but I'm not a professional programmer. I contributed an extra function to a PHP project once, but on submission it was rewritten and, in hindsight, the functionality was completely useless anyway. I was actively encouraged by the project members who were very supportive but I can't help feeling I was generating more work than was necessary for them. I suppose the question is - Are novice programmers a hindrance to a project?

Using 'in' to match an attribute of Python objects in an array

I don't remember whether I was dreaming or not but I seem to recall there being a function which allowed something like, <pre><code>foo in iter_attr(array of python objects, attribute name)</code></pre> I've looked over the docs but this kind of thing doesn't fall under any obvious listed headers

Connect PHP to an AS/400

I've got an upcoming project wherein I will need to connect our website (PHP5/Apache 1.3/OpenBSD 4.1) to our back-end system running on a iSeries with OS400 V5R3 so that I can access some tables stored there. I've done some checking around but am running into some roadblocks. From what I've seen the DB2 extensions and DB2 software from IBM only run under Linux. I've tried compiling the extensions with all the software from IBM and even tried their precompiled ibm_db2 extension with no luck. IBM only supports Linux so I turned on the Linux emulation in the kernel but that didn't seem to help anything. If anyone has run across getting everything to run natively under OpenBSD that would be great, but what I think I may have to do is setting up a second server running CentOS with DB2 installed (most likely via ZendCore for IBM since it seems to do all this for me) and the driver so that I can set up a small transaction server that I can post against and get a JSON representation of the DB2 data that I need. Does the second option seem overkill or does anyone else have any better ideas?
