FIX: CFrameWnd::UpdateFrameTitle() Removes Text after Hyphen (113294)

This article was previously published under Q113294 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.
