cv::Exception at memory location 0x003AEBB8
When i run my program in VS 2012 ( in 2010 everything was working ) this is the error im getting :
Unhandled exception at at 0x7698C41F in test.exe: Microsoft C++ exception: cv::Exception at memory location 0x0034EE30.
and in my console program i see this : OpenCV Error : Assertion failed (size.width)0 && size.height)0) in unknow function, file C:\slave\builds\WinInstallerMegaPack\src\opencv\modules\highgui\src\window.cpp
When i debugging my code, its craching here : imshow("Img Source", ImgSource);
here my full code ( the same exact code working in vs 2010 )

please check, if the image was actually loaded:
if ( ImgSource.empty() ) cout < "Fuck " << endl;
in debug mode, im going in this if
so, the usual : set the working dir in the debugger settings, or use an absolute path for imread ...
