======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - The Microsoft Foundation Classes (MFC), used with:
    - Microsoft Visual C++, version 1.0 
    - Microsoft Visual C++ 32-bit Edition, version 1.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When an SDI or MDI application is created using AppWizard, the
CFrameWnd::UpdateFrameTitle function normally inserts the document name into the
title of the corresponding application's frame window. If a hyphen is inserted
into the title of the application, however, the title will be truncated at the
inserted hyphen and the document name will be appended to the right of the
hyphen.

For example, if the application has the name "My-WinApp" and the document name is
FIDO.DOC, when the document is opened, the resulting text will appear in the
caption bar as "My - FIDO.DOC".

CAUSE
=====

The following code is an excerpt from WINFRM.CPP, beginning on line 857:

   void CFrameWnd::UpdateFrameTitleForDocument(const char* pszDocName)
   {
       ...

       // keep the original title up to first '-'
       LPSTR pchDash = _AfxStrChr(szText, '-');
       LPSTR pchPrev;
       if (pchDash != NULL &&
          *(pchPrev = AnsiPrev(szText, pchDash)) == ' ')
             pchDash = pchPrev;

       //  remove anything after "-" or " -"
       if (pchDash != NULL)
             *pchDash = '\0';

       // get name of currently active view
       if (pszDocName != NULL)
       {
           lstrcat(szText, " - ");
           lstrcat(szText, pszDocName);
           // add current window # if needed
           if (m_nWindow > 0)
               wsprintf(szText + lstrlen(szText), ":%d", m_nWindow);
       }
   }

The cause of the problem is line 871, where a NULL character replaces the first
hyphen found in the title.

STATUS
======

Microsoft has confirmed this to be a problem with version 2.0 of the Microsoft
Foundation Class Libraries for Windows and Windows NT. This problem was
corrected in the Microsoft Foundation Classes version 2.5.
