debugger line numbers are off

Environment: Win95, VC++ 4.2b
Whenever I try to step through my code it seems
like the line numbers in the debugger are off by a
few lines in the MFC source code. As a result a
call to any of the MFC functions takes me to the
middle of the function. I have seen this to mostly
happen in the DAO core CPP files. I know I didn't
receive any errors when I installed the 4.2b
patch. Has anyone else experienced this problem?
Is there a fix?

That's impossible: the patch will always generate _some_ errors
because the patch patches any file you might possibly have installed,
but no user ever has _every_ file installed.

The PDB files you're using to build, or that you're referencing while
debugging (or both) are out-of-synch with your source code. Either
your source wasn't patched, or your PDBs weren't patched while
building. Or, while debugging, you're referencing code that wasn't
patched, or you're referencing PDB files that weren't patched.

This performance was not lip-synched.

Yes. Usually when someone has checked source back in and not built the DLL=20
or EXE in the master directory. Try rebuilding the entire project.

Check the "Browse Info" tab under "project Settings".
I think you'll find "Build" check-box has been
reset.

I had a similar symptoms when I installed both MSVC 4.1
and 4.2, so run-time sources didn't match actual libraries.
That might be a reason.

This happens when the object code is not up to date.
For example, enter some empty line in your source code and try to
debug without recompiling your app. When you go to the modified file
the source code is not "aligned".

You must rebuild the DAO sources.
