Hie,

Im trying to do a credential using a sample from SDK 7.0. So, i edit the SampleHardwareEventCredentialProvider project. I want to add an OpenCV window there but the window is not showing.

This is the code:

HWND _hWnd = (HWND) cvNamedWindow("Input",CV_WINDOW_AUTOSIZE);

Am i do it wrong?

Please help me.

You provided pretty few informations to work with.

But i can see that you are using the old (C-Style) Version of openCV, which isn't necessary if you're working with C++. You should rather use the new API which is much more convenient to use.

For example to read and show an image in a window you can use:

C++

Mat img = imread("image.jpg");
namedWindow("image", CV_WINDOW_AUTOSIZE);
imshow("image", img);

Some fundamentals of working with images in openCV are explained here:
