FIX: Assertion Using Multiple %1 (or %2) in AfxFormatString1

MORE INFORMATION

1. Create a .CPP file using the sample code provided below.
2. Create a new Windows project that uses MFC, and add the .CPP that you just created to the project.
3. Use App Studio to create a string table that includes the following two entries:

   IDS_THETEMPLATE = File %1 has some text associated with it.
   IDS_THENEWTEMPLATE = File %1 and %1 have associated text.

4. Save the string information in an .RC file.
5. Add the newly created .RC file to the project by choosing Edit from the Project menu.
6. Perform a build. Visual Workbench creates a .DEF file for you if you do not supply your own .DEF file.
7. Run the program to view the assertion.

     // This works fine
     AfxFormatString1( theOutputString, IDS_THETEMPLATE,
                       "filename.ext" );
     TRACE("theOutputString=%s\n", theOutputString);

     // Comment this out to avoid Assertion
     AfxFormatString1( theOutputString, IDS_THENEWTEMPLATE,
                       "filename.ext");
     TRACE("theOutputString=%s.\n", theOutputString);

     return FALSE; // Terminate the program
   }
