I have attempted to create a MDI but was unsuccessful. The Child window created could not be seen when maximaised, and could not be closed by pressing the x button. Can anyone tell me wat went wrong, someone with similar experience.

Hi roticv

I guess you process WM_COMMAND. If you do you must call DefFrameProc if you dont process the message.

Hi KetilO,
I did process DefFrameProc. I still do not know what went wrong in my code. I do hope you can help me out. btw, thanks for your help

Have you used DefMDIChildProc in your child window procedure?

im just throwing this out there because i ran into a similar. i was able to create my mdi child windows but after being maximized the min/max/close buttons were unresponsive.

the problem was i was using a ret when handling the WM_COMMAND message. mine looked like this:

.if wParam == 8000
invoke MakeMDIchild

i took the ret out and it worked fine. im curious about what the end of your wndproc procedure looks like. should look something like:

invoke DefFrameProc,hWin,hClient,uMsg,wParam,lParam

yeah.. thanks for your help smurf. It did sure solve all my problems. So the problems lies on that you must return DefFrameProc.
