hi friends

I have a parent window which have some child windows (Like MDI in VC) , say 16.
Because these child windows have no caption bar and border , so  i need to draw the broder myself
when the user select one of them. Drawing broder is not the problem , the problem is that when the user switch to other window and click it . I need to erase the broder of privious window and draw broder for the new selected window. BUT , how to ease the broder for the privious window?
I have tryed sending WM_PAINT and WM_ERASEBACKGROUND message to the privious window, but
it does not work.
Any idea?
I hope i can understood by you. Thank you very much!
