Question

I have an MFC project where everything was working perfectly fine and I checked in my code in source control (perforce). All of a sudden the .rc file wouldn’t open. When I try to open, it gives an error Guideline must specify type @ line# 410 which is this:

#ifdef APSTUDIO_INVOKED
GUIDELINES DESIGNINFO
BEGIN
    IDD_ABOUTBOX, DIALOG
    BEGIN
        , 50
    END

Now granted, it does seem to be missing an entry when I compare it to other projects but I didn’t manually change anything in the rc file and VS2010 has been handling it exclusively. I don’t know when these entries got changed. I got everything from perforce to a new folder and rc file would still not open! Is there any better solution or do I have to just change the entries manually in hope that it will fix it?

Answer 1

It turned out the rc file was somehow corrupted by VS2010 at some point. I had the original version in source control and re-merged them manually to fix it. The corrected code looks like this:

GUIDELINES DESIGNINFO
BEGIN
    IDD_ABOUTBOX, DIALOG
    BEGIN
        LEFTMARGIN, 7
        RIGHTMARGIN, 163
        TOPMARGIN, 7
        BOTTOMMARGIN, 55
    END
END

The VS2010 seems to corrupt the rc file randomly when you copy/paste a dialog to create a new one.
