I am working on Credential Provider using VC++. Where i want start a web cam using

opencv classes and libraries. Added all the header files and its libraries to

credential provider for accessing.

Code Like this:
cvCapture *camera = 0;
IplImage *frame;
IplImage *showimg;
cvNamedWindow("Input", CV_WINDOW_AUTOSIZE);
camera = cvCaptureFromCAM(0);
cvSetCaptureProperty(camera, CV_CAP_PROP_FRAME_WIDTH, 360);
cvSetCaptureProperty(camera, CV_CAP_PROP_FRAME_HEIGHT, 240);
frame = cvQueryFrame(camera);
showimg = cvCloneImage(frame);
cvShowImage("Input", showimg);

added this code to display the cam on the window.

but its not displaying cam but displaying the window and giving the error Like this:

"This application has requested the runtime to terminate it in a unusual way. Please contact the application's support team for more information".

Can anyone give me some idea, how to solve this issue.

Thanks in Advance.

Did you use logging to find out what operations were successful, what were not? Another advice: create a test/prototype version of product with the same code base, to be able to debug. You would catch most of the problems.
