Q:

The exception is not caught in vc++

In my application I got an exception message. This occurs when I throw false when an if() condition fails. The error message I got is as below
Unhandled exception at 0x74fe812f in MyApp.exe: Microsoft C++ exception: bool at memory location 0x0015c87b..

My code that generates this error is 
if((dwStatus!= 302) && (dwStatus< 200 || dwStatus> 299))
    throw false;

Here dwStatus is a DWORD which got from pHttpFile->QueryInfoStatusCode(dwStatus) where pHttpFile is an object reference of CHttpFile
The codes are in a try block and appropriate catch blocks are also there.
How this error occurs.
EDIT
This is the catch block
catch(CException* pErr)
{
    TCHAR szErr[1024];
    pErr->GetErrorMessage(szErr,1024);
    pErr->Delete();
    bRet = FALSE;
}

A:

Your catch block is catching a CException* type of exception, but you are throwing a bool type of exception. If you want to catch that exception, you'll need a catch block that catches exceptions of type bool:
catch(bool exception)
{
  //report the exception, or recover, or whatever
}
