We have a problem debugging legacy code that uses MFC
classes, especially CString in a mixed mode assembly.

There is no tooltip support diplaying the contents of a
MFC string. Tooltips work for STL strings only.

It is possible to add a Description for legacy classes like
CRect into the mcee_mc.dat file to assist the debugger but
this mechanism works for non template classes only.

Is there any way to display the contents of a CString
class in a tooltip window while debugging a managed module.

Thanks in advance

Hi Harald ,

What is your VS.NET version?

This is known issue.  CDebugObject::GetCorElementTypeFromField() was not
handling classes correctly.

It will fix in the new VS.NET version.

Thanks
