We

have

announced

that

Visual

Studio

now

includes

Xamarin

at

no

extra

cost

including

Community

Edition

which

is

free

for

individual

developers

open

source

projects

academic

research

education

and

small

professional

teams

There

is

no

size

restriction

on

the

Community

Edition

and

offers

the

same

features

as

the

Pro

Enterprise

editions

Why

would

you

want

to

discourage

people

from

using

XamarinForms

And

why

is

Visual

Studio

support

available

in

the

free

version

but

not

the

paid

Indie

version

Even

though

Xamarin

looks

promising

My

personal

thinking

is

starter

edition

is

restrictive

and

feels

like

demo

version

This

makes

developer

to

refrain

from

using

Xamarin

for

production

application

to

avoid

considerable

investment

for

Xamarin

subscription

during

initial

periods

and

then

every

year

A

considerable

lower

price

slab

or

more

flexible

starter

edition

will

be

practical

the

question

to

support

team

they

replied

with

following

You

can

develop

an

app

with

Xamarin

for

commercial

usage

there

is

no

extra

charge

We

only

require

you

to

comply

with

Visual

Studios

licensing

terms

which

means

that

in

companies

of

less

than

employees

with

less

than

USD

annual

revenue

you

may

use

Visual

Studio

completely

free

including

Xamarin

for

up

to

developers

However

after

you

pass

those

barriers

you

would

need

a

Visual

Studio

license

which

includes

Xamarin

If

you

go

crossplatform

page

then

read

and

scroll

to

the

it

appears

that

Microsoft

is

including

Xamarin

and

upon

installing

it

you

do

have

as

James

said

the

Xamarin

In

go

to

Tools

to

see

your

I

do

not

know

the

limitations

any

date

of

this

Account

Still

I

dont

know

about

you

but

the

Community

edition

I

installed

expires

in

less

than

days

Check

the

Help

menu

go

on

your

status

to

check

Lets

say

Xamarin

Starter

edition

is

free

but

Visual

Community

has

an

expiration

date

So

the

bigger

question

might

be

whether

Visual

will

be

free

Without

Xamarin

though

Microsoft

is

offering

C

tools

for

Interesting

that

Microsoft

is

promoting

a

C

free

However

crossplatform

C

really

means

Windows

Impossible

to

tell

from

that

the

Random Number Generation in R closed Ask Question 0 I am looking to generate a set of five random numbers in R The tricky part however is that I wish for the values to be in a sequence that is first decreasing then increasing that is the first random number will be larger than the second which will be larger than the third The fourth will be larger than the third and the fifth will be larger than the fourth To explain this more clearly 1High 2Mid 3Low 4Mid 5High while still maintaining a mean of approximately 2000 for the largest first and last values I suppose the first and fifth values should be around 2000 the second and fourth values can be around 1500 but I imagine can fluctuate quite a bit and the third value should be relatively lower The SD can vary as well So for example a satisfactory string could be 2300 1843 987 1300 1900 To bring in some biological background I am attempting to describe a complex system in the patterns of abundance in oystercatchers based on the tides I know from data that the mean value for oystercatchers while the tide is low is 2000 The values for mid and high tide however are not known for this particular estuary I imagine that high tide will have lower numbers than mid and low tide r random improve this question Ben Bolker 132k 11 221 307 asked Mar 25 16 at 1521 Ryan Rothman 58 1 8 as unclear what youre asking by nrussell Hong Ooi Julius Vainora Frank nicola Mar 25 16 at 1601 Please clarify your specific problem or add additional details to highlight exactly what you need As its currently written its hard to tell exactly what youre asking See the How to Ask page for help clarifying this question If this question can be reworded to fit the rules in the help center please edit the question 1 What would be the mean of the Mid and Low sets Paul Rougieux Mar 25 16 at 1524 4 hints Do you want the mean to be exactly 2000 in which case youll have to use something like x 2000xmeanx Ben Bolker Mar 25 16 at 1524 To bring in some biological background I am attempting to describe a complex system in the patterns of abundance in oystercatchers based on the tides I know from data that the mean value for oystercatchers while the tide is low is 2000 The values for mid and high tide however are not known for this particular estuary I imagine that high tide will have lower numbers than mid and low tide Therefore if it is possible to keep 2000 as the mean but have the numbers randomly generated with some kind of weight to them that would be the ideal Ryan Rothman Mar 25 16 at 1528 1 Could you post an example of 5 numbers that would satisfy your requirements nicola Mar 25 16 at 1533 1 Um x runif5 z sortxc53124 meanx 2000 Frank Mar 25 16 at 1542 show 14 more comments 1 Answer oldest 0 As said be Ben Bolker rndvalues rnorm 5 mean 2000 sd 1 rndvalues 1 1999909 1999656 2001798 2000352 2000114 orderedrndvalues rndvalues order rndvalues decreasing TRUE orderedrndvalues 1 2001798 2000352 2000114 1999909 1999656 stupid solution to make the 3rd element the minimum result c orderedrndvalues 1 2 orderedrndvalues 5 orderedrndvalues 4 3 result 1 2001798 2000352 1999656 1999909 2000114 answered Mar 25 16 at 1527 R Yoda 4053 18 40 decreasingTRUE would be the ideal way to go if the values could decrease up until the 3rd integer then go back upward for the 4th and 5th Ryan Rothman Mar 25 16 at 1530 A yes I overlooked that This requires a second but which higher values shall I choose any interdependencies between the values 1 and 2 with 4 and 5 R Yoda Mar 25 16 at 1532 I suppose the 1st and 5th values should be around 2000 the 2nd and 4th values can be around 2000 but I imagine can fluctuate quite a bit and the 3rd value should be relatively lower The SD can be very varied as well So for example a satisfactory string could be 2300 1843 987 1300 1900 Ryan Rothman Mar 25 16 at 1541 RyanRothman I have undeleted my answer even though I think it is not exactly what you wanted the right side of the minimum in index 3 always contains lower values than the left side so it is not really random R Yoda Mar 25 16 at 1636 for the purposes of my model it should suffice Thank you very much for your help on this Ryan Rothman Mar 25 16 at 1646 Not the answer youre looking for Browse other questions tagged r random or ask your own question asked 2 years 9 months ago viewed 433 times active 2 years 9 months ago

Thanks

a

lot

Its

working

I

have

one

question

if

user

enters

a

text

data

which

is

already

present

say

Vin

already

exist

than

i

dont

want

to

write

duplicate

entries

to

file

how

to

achieve

it

Jun

at

For

that

in

the

step

you

need

to

ask

IF

the

array

CONTAINS

already

the

new

Vin

IF

it

does

then

skipping

it

ELSE

then

go

ahead

and

adding

the

new

Vin

So

now

is

your

turn

for

coding

it

I

meant

the

inside

the

Unfortunately

you

can

not

add

an

application

as

a

member

of

Azure

AD

group

Though

the

official

document

for

the

Powershell

cmdlet

AddAzureADGroupMember

doesnt

make

clear

you

can

not

use

Applications

ObjectId

as

the

RefObjectId

absolutely

you

can

not

use

it

You

can

not

add

an

application

as

a

member

of

Azure

AD

group

neither

For

example

we

will

create

for

readers

and

for

writers

Then

based

on

groups

claim

I

will

figure

out

the

right

access

level

For

your

scenario

Im

afraid

that

you

couldnt

achieve

this

for

now

I

understand

why

you

need

this

According

to

your

request

my

thought

is

assigning

your

application

from

Enterprise

Application

to

Groups

or

users

and

manger

users

with

different

access

rights

However

you

can

not

choose

more

roles

for

the

selected

group

The

only

one

role

is

default

access

If

want

to

define

more

roles

for

the

app

you

can

refer

to

this

documentation

I

also

tried

to

use

Azure

AD

RBAC

and

create

new

conditional

access

for

my

test

appbut

all

dont

have

read

only

this

choice

You

can

also

put

your

idea

in

Azure

Feedback

Forum

azure

team

will

see

it

Also

I

will

upvote

your

idea

Update

Currently

you

can

add

a

service

principal

to

an

AAD

Group

Example

spn

GetAzureADServicePrincipal

SearchString

yourSpName

group

GetAzureADGroup

SearchString

yourGroupName

AddAzureADGroupMember

ObjectId

groupObjectId

RefObjectId

spnObjectId

Updated

Recently

I

also

see

lots

of

users

want

to

assign

roles

to

a

service

principal

to

let

the

service

principal

have

some

permissions

to

access

to

the

app

with

a

role

I

want

to

make

clear

here

Rolebased

authorized

should

be

used

for

users

NOT

applications

And

its

not

designed

for

applications

If

you

want

to

give

some

different

permissions

you

may

consider

to

assign

application

permissions

to

your

service

principal

instead

You

can

expose

your

Web

AppAPI

with

application

permissions

by

editing

the

Manifest

in

app

registrations

You

can

go

to

Azure

portal

Azure

Active

Directory

App

registrations

Select

your

App

Manifest

In

appRoles

you

can

insert

content

like

this

allowedMemberTypes

Application

displayName

Access

to

the

settings

data

id

isEnabled

true

description

Administrators

can

access

to

the

settings

data

in

their

tenant

value

SettingsdataReadWriteAll

Then

you

can

go

another

app

registration

you

want

to

give

permission

Settings

require

permissions

Add

Search

the

application

name

you

want

to

access

Choose

the

application

permission

you

created

before

Therefore

your

sp

can

obtain

a

token

with

that

application

permissions

in

token

claims

Also

for

authorization

from

the

resource

you

need

to

add

code

logic

to

give

control

policy

for

that

token

with

SettingsdataReadWriteAll

claim

A

doesnt

need

to

specify

a

port

When

you

set

the

port

parameter

it

assumes

that

your

launch

will

include

the

inspect

parameter

with

that

port

If

you

have

to

specify

the

for

then

you

can

include

the

I

think

the

reason

the

OPs

code

does

not

work

is

because

once

you

call

Remove

you

are

changing

the

Length

of

drr

When

you

call

Delete

you

are

not

actually

deleting

the

row

until

AcceptChanges

is

called

This

is

why

if

you

want

to

use

Remove

you

need

a

separate

loop

Depending

on

the

situation

or

preference

Calling

Remove

is

the

as

calling

Delete

and

then

calling

AcceptChanges

Note

that

if

you

call

Delete

then

you

should

call

AcceptChanges

if
