CStatic::SetBitmap for

Hi, I think this is an easy question.  I am trying to set a bitmap into a CStatic object, using SetBitmap.  It works fine for resources, but I would like to use it for a bitmap I am creating on my own, and is continuously being updated with input from a camera.  I was using BitBlt, and this was working, but I wanted a way to refresh parts of the bitmap without having to blt all the time.  So I thought giving the bitmap to a static control, and letting it take care of the blitting and rectangle invalidations itself, and I just hand it the bitmap.  The bitmap is named mCaptureBmp (initialized with camera data with SetDIBits()) -- but instead of BitBlt(), I do mStcCapture.SetBitmap(mCaptureBmp);  I just get a blank static control.

What could be wrong?

Not an answer to what is wrong (probably not enough info), but have you tried SetDIBitsToDevice?  

This function will allow you to specify what segment of the image you want to display.  Also useful is StretchDIBitsToDevice.

At least people won't laught at you when you tell them how you did it... :)

Unfortunately, a static control does not support displaying a DIB. It converts the DIB to a DDB when displaying. Then all the color palette information is lost. So you got a black one. Don't use a static control in your case.
