In following MSDN documentation
http://msdn.microsoft.com/en-us/libr...18(VS.85).aspx

for WM_NCHITTEST message It is stated like this :

The return value of the DefWindowProc function is one of the following values, indicating the position of the cursor hot spot.
.....
.....
HTCLOSE - 20 - In a Close button.
.....
HTSYSMENU - 3 - In a window menu or in a Close button in a child window.
.....

But i could not see HTSYSMENU being returned for a "Close button in a child window".
Tried different scenarios like SDI/MDI , dialog with a child dialog etc .

Can anybody explain a scenario for HTSYSMENU being returned for a "Close button in a child window".

Thanks
