Can I destory other thread's child window?

[fitatc]

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.
