Unfortunately those symbols are no longer exported in the release version of
MFC71.DLL. They are only exported in the debug versions. I'm not sure if
this was an oversight on Microsoft's part or whether it was by design.
To verify this, you can do a "find in files" of afxRichEditState in the DEF
files in the installation folders. Notice under VC6.0 it shows up under
both the debug and release DEF files. Under 7.1 it only shows in the debug
DEF files.
The fix you talked about is already fixed in VC7.1, so maybe you could
change your code back to using the standard rich edit control, and not your
own copy. Or to properly fix the problem, bring in all the definitions of
the classes you need (copy them in)

Hi,
I have a code that builds under VC6.0, but fails to link in VC7.1.
The offending code is as follows:
_AFX_RICHEDIT_STATE* const pEditState = _afxRichEditState;
The linker errors are:
----------------------
LVBaseDetailsView.obj : error LNK2001: unresolved external symbol
"__declspec(dllimport) class CProcessLocal<class _AFX_RICHEDIT_STATE>

void * __thiscall _AFX_RICHEDIT_STATE::`scalar deleting
destructor'(unsigned int)" (??_G_AFX_RICHEDIT_STATE@@UAEPAXI@Z)
----------------------
The code above is part of legacy code, which I am porting to the .NET
compiler. I cannot drastically change the code to do away with such things
since I saw in the code documentation that this was introduced to solve
some bug where the code crashes if a find dialog is opened in a RichEdit
view.
When I searched MSDN / Google I found very little information regarding
this. Later I realized it may be because _afxRichEditState is an
undocumented class, derived from the undocumented CNoTrackObject.
Does anyone know of this problem and a solution to this?
Should I link to some library explicitly in VC7 .NET?
Warm regards,
Sena
