End Google Ads 201810 - BS.net 01 --> I know that sending WM_CLOSE or WM_DESTROY or WM_QUIT can destory a window created by other thread.
But this is not working when the target window is child window(With WS_CHILD Style, like property window in SDI).

[My Question is]
Can I destory other thread's child window?
If I can, please give me some advise about how to do it.
