In my Win32 application, a child window is created by a third party SDK.The Window creation process is transparent and I cannot associate a WndProc method with the child Window. I want to be able to capture child window messages in parent window. How can I do this? Any help would be highly appreciated.

Have you tried CWnd::SubclassWindow? – Mark Ransom Jul 12 '11 at 22:15

2You can trivially associate your own window proc with `SetWindowLong` and `GWL_WNDPROC`. You can do this for each and every window in your process. See this: http://msdn.microsoft.com/en-us/library/ms633570(v=VS.85).aspx#subclassing_window – David Heffernan Jul 12 '11 at 22:15

Thank you very much David. This really solved my problem. – Farooq Zaman Jul 13 '11 at 01:14

Have you looked at SetWindowsHookEx? Or if that seems like overkill you could probably just use SetWindowLong with GWL_WNDPROC and define your own custom WinProc then forward to the child window.
There is a pretty good article on MSDN about it.

Hi Again, does this solution works for multi-threaded application? In my application Parent window is in main thread while child window is in separate thread. I have tried subclassing but it's not working. – Farooq Zaman Jul 13 '11 at 02:06
