Why does GetObject return an BITMAP with null bmBits?

Question

Context: I\'m trying to take a screenshot of another window to feed it into OpenCV. I found some code on the web that should be able to convert a BITMAP to something OpenCV can

Answer 1

One thing which you could do is to look at the return value of GetObject. If 0 you know something has gone wrong. Something wrong with the parameters of the call.
