I am trying to make an application work under wine. The app is probably an MFC app, that defenitely uses MDI. The problem boils down to this - it tries to create an MDI window by doing SendMessageA to a message of type "WM_MDICREATE". Here's the catch - the class it wants to use is in Unicode. This fails for obvious reasons.
I'm trying to find my way around the MDI setting, and phrase a regression test. However, I cannot seem to create the exact same circumstances. When looking at the original app using Spy++, I see that the application has a window from the very start of the app (long before it sends WM_MDICREATE), which does not appear to have WS_EX_MDICHILD set, but which has a child window of class "MDIClient".
Running the same app in Wine using --debugmsg +win,+class, I can see that it asks to open a window of class "mdiclient". I do not, however, see anywhere that such a class was ever registered! Furthermore - the call succeeds.
Can anyone enlighten me? Is this window necessary whenever an MDI is present? If so, what function do I use on the parent window to tell it that it is to be an MDI container?
Many thanks,
Shachar
