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.

The same way you would call a class anywhere. But perhaps, that is not really what you are asking.

You don't call classes. You call functions. You instantiate objects of a particular class and use it to call functions from that class.
