What is a robust method for capturing screen of child window in Windows 7?
- by Dogan Demir
Pardon my frustration. I've asked about this in many places and I seriously don't think that there wouldn't be a way in Windows 7 SDK to accomplish this.
All I want, is to capture part of a 'child window' ( setParent() ) created by a parent. I used to do this with bitblt() but the catch is that the child window can be any type of application, and in my case has OpenGL running in a section of it. If I bitblt() that, then the OGL part comes blank, doesn't get written to the BMP.
DWM, particularly dwmRegisterThumbnail() doesn't allow thumbnail generation of child windows. So please give me a direction.
Thanks.
