When I just declare
class
COurTabMdiWnd : public CExtTabMdiWnd { /* empty class */ };
And I use that class in my mainframe, I get an error when Create() is called. The error says: Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call. This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention. I must have done something wrong with my class declaration here. Tried adding DECLARE_DYNCREATE and stuff, but it makes no difference. Does anyone know what I’m doing wrong?

Some observations: - My project file is unchanged (I’m not the only one working on the project, but Source Safe says no relevant changes)
- Didn’t touch Prof-UIS.h.
- Didn’t override, CExtTabMdiWnd::CExttabCreate().
- The constructor still seems to work fine.
- When I start reusing the CExtTabMdiWnd again, it all works fine.
First I blamed the incremental linker, so I tried cleaning and rebuilding the whole solution, but this didn’t help either. Actually I’m still blaming the linker or the compiler. In that case you can’t help me. I was just hoping you have seen this happen before.

We faced similar problems but only when compiling a project with Prof-UIS and MFC with some service pack for Visual C++ 6.0 and running with MFC DLL with some other service pack and only in a debug configuration. Could you try to re-produce the problem with some of our sample applications and try to re-produce it on some other computer? If it’s re-produced in your project only, we need a closer look at all the settings and source code.

Did you change the default calling convention and/or byte alignment options in the settings of your project? If yes, you should do the same changes in Prof-UIS and re-build it.
