I now have a simple ocx and an exe that has nothing else than this ocx in it. The ocx appears as black circle on white ground in the upper left corner (right, the wizard made ocx) In Windows it works without a problem but in wine there's an exception upon creating the ocx. It happens with both builtin and native msvcrt.dll.
Well, the exception will be there in all cases, but it should be handled correctly with native msvcrt, I'd be very suprised if this didn't work. Anyway it should now work with the builtin too, thanks for the detailed report.
Well, partly. I found out that it works if I start it in wine "wine app.exe". But if I start it with "winedbg app.exe" I still get this exception. So after all it's maybe not an msvcrt fault but a winedbg one. Maybe because it's catching every exception immediately even if it would be handled later by the program.
To find out what's going on inside the MFC I added all MFC-sources to my prg. Here's the new bt with MFC-files (original file names from MSVC6). The original MFC42.dll is loaded because of the ocx.

What is this error that is showing up while loading the files?
Error: Copyfield list mismatch (4<>3): enum CTestocxCtrl::__unnamed struct none
Maybe this has something to do with it. Using wine from cvs 2002-10-11 with all builtin.
