I have my own code that samples pixel colour, https://pastebin.com/4EMd765h and now I am trying to add the feature of saving the Device Context to a .bmp file, so I found this code https://books.google.ca/books?id=9MS9BQAAQBAJ however there is one problem: The book example screenshots the whole desktop and I only want a screenshot of a given window. Is there a way to modify the black hat example into something that only screenshot a window given its handle? It would have been easier to help if you had showed us the code you're trying to modify. I assume the code you're copying does GetDC(0) to grab a DC for the desktop. If you instead pass the window handle of the window you want to snapshot, just pass that to GetDC. You'll want to use GetWindowRect to find the size of the window. — Tim Roberts, t...@probo.com<mailto:t...@probo.com> Providenza & Boekelheide, Inc.
