MFC Dialog Font Substitution Under DBCS System

The information in this article applies to:

- The Microsoft Foundation Classes (MFC), included with:

   Microsoft Visual C++, 32-bit Edition, versions 4.0, 4.1

SUMMARY

When an MFC application is run under a DBCS (Double-byte Character Set, including Japanese, Chinese and Korean) in Windows NT or Windows 95, the default font specified for the dialog boxes within that application will be changed to the system font if they were originally set as "MS Sans Serif" or "Helv" in the RC file.

MORE INFORMATION

CDialog::DoModal eventually calls the following code (excerpt from MFC source code dlgcore.cpp):

   // On DBCS systems, also change "MS Sans Serif" or "Helv" to system
           font.
   if ((!bSetSysFont) && GetSystemMetrics(SM_DBCSENABLED))
   {
      bSetSysFont = ((strFace == _T("MS Sans Serif")) ||
         (strFace == _T("Helv")));
      if (bSetSysFont && (wSize == 8))
         wSize = 0;
   }
   if (bSetSysFont)
   {
      CDialogTemplate dlgTemp(lpDialogTemplate);
      dlgTemp.SetSystemFont(wSize);
      hTemplate = dlgTemp.Detach();
   }

This font substitution does not occur on non-DBCS versions of Windows NT or Windows 95.
