Re: Importing MFC resources

If you have

IDD_WHATEVER DIALOG ...

you can't tell if you are using a string name or an integer to name the
dialog. If you
have

#define IDD_WHATEVER 200

preceding it. The preprocessor converts it to

200 DIALOG ...

and now it is treated as a numeric ID.

If you do FindResourceEx, you must either use a string name, e.g.,

FindResourceEx(module, RT_DIALOG, _T("IDD_WHATEVER"), 0);

but if the #define IDD_WHATEVER 200 is done, you have to do

FindResourceEx(module, RT_DIALOG, MAKEINTRESOURCE(IDD_WHATEVER), 0);
or, if you like to live dangerously you could write
FindResourceEx(module, RT_DIALOG, _T("#200"), 0);

but this would not be able to track changes in the resource IDs, and is
generaly not
recommended in this context.

Note that RT_DIALOG is MAKEINTRESOURCE(5)

I store an RTF resource as a set of names,

HELP_NAME1 RTF res\name1.rtf
HELP_THING RTF res\thing.rtf

and so on, and when I want to create a resource name from a string (the
strings are
computed from various contexts)

CString s = _T("HELP_");
s += computed_name;

FindResourceEx(AfxGetInstanceHandle(), _T("RTF"), s, 0);

and it works very well.
