问题
I have an old MFC application I've recently updated to include code that uses CDatabase to access an old MDB.
This works, but when an internal error occurs, I get an assertion in dbcore.cpp that it could not load the error string resource.
After some research, I added the following line to my application's RC file.
#define APSTUDIO_READONLY_SYMBOLS
/////////////////////////////////////////////////////////////////////////////
//
// Generated from the TEXTINCLUDE 2 resource.
//
#ifndef APSTUDIO_INVOKED
#include "targetver.h"
#endif
#include "afxres.h"
#include "afxdb.rc" // <<======= I ADDED THIS LINE HERE!!!
/////////////////////////////////////////////////////////////////////////////
#undef APSTUDIO_READONLY_SYMBOLS
This solved the problem. I now got a meaningful message for internal errors. However, now if I try to save my resource file using the resource editor, I get an error.
How can I get meaningful internal database messages and still be able to save changes to my resource file?

Per Joe Willcoxson's comment, moving the added line to my RC2 file solved the issue. I now have the necessary database resources, and I'm still able to edit and save resources in the resource editor.
