Hi,

I am migrating my VC++ 6.0 Application to Visual Studio 2005 for windows 7.Successfully i have migrated my application to Visual studio 2005 without any errors. But It throws an Exception Messagebox " Invalid Argument was encountered" while loading the application.Otherwise the application is working fine.The messagebox pops up everytime while opening the application.I have googled and tried out a lot of methods to identify the problem.But I can't.I got the below message in output window while debugging,

C++

First-chance exception at 0x7589d36f in Usecpol.exe: Microsoft C++ exception: CInvalidArgException at memory location 0x0012ed50..

Is there any way to suppress the message box???

You need to use your debugger to step through the code and find out where the assertion occurs.

Debugger points out the below line from "C:\Program Files\Microsoft Visual Studio 8\VC\crt\src\crtexe.c"

#ifdef WPRFLAG
mainret = wWinMain(
#else /* WPRFLAG */
mainret = WinMain(
#endif /* WPRFLAG */
(HINSTANCE)&__ImageBase,
NULL,
lpszCommandLine,
StartupInfo.dwFlags & STARTF_USESHOWWINDOW
? StartupInfo.wShowWindow
: SW_SHOWDEFAULT
);
#else /* _WINMAIN_ */

It should not give errors in the system library, try a full rebuild of your project.

Ya.. I have tried a full rebuild also.The same thing is happening..

I can only guess that something in your project settings or headers is referring to an old version which is not fully compatible with the libraries on your system. However, without looking at the actual project it's impossible to guess what it may be.
