error in dll created

[marzioni]

hello at all,
i have built a dll with pelles c 5, and i obtain the follow message:

Building contes32.obj.
warning #2024: Empty input file.
Building CONTES32.res.
Building contes32.dll.
Done.

when i perform a double click on the dll file to open with pelles c 5, pelles gives to me the follow message:
Error reading from file 'contes32.dll'.
It's impossible to find the name of resource specified in the image's file.

what is wrong?

thanks in advance, marzioni

I suggest, you need to post the project.

My guess is that you need to define the resource identifiers.

For example

AIUTO BITMAP "res1.bmp"
AIUTO2 BITMAP "res2.bmp"
BOTTOM BITMAP "res3.bmp"

AIUTO has no value associated with it.

Make a header file (.h) that is included in the RC file containing all identifier defines.

e.g.

// start contes32.h
#define AIUTO 1000
#define AIUTO2 1001
#define BOTTOM 1002
//end

You will need to define all resources hopefully with unique identifiers. That is for 'cursors', 'icons', 'bitmaps', 'dialogs', etc.

Include that header file in the RC file like so.

#include "contes32.h"

i have tried with a little piece of contes32.rc file (see below) and without h file the dll created works fine.

#include <windows.h>
#include <commctrl.h>
#include <richedit.h>

LANGUAGE LANG_ITALIAN,SUBLANG_ITALIAN

AIUTO BITMAP "res1.bmp"
AIUTO2 BITMAP "res2.bmp"
BOTTOM BITMAP "res3.bmp"

Ok, well, it seems that the compiler does not like various names.

These for example
PRINT_BLACK
PRINT_PROC
PRINT
MESS_CODICI

And a few more I can't remember.

I have changed various names so that it is ok. See the attached RC file.

You are better off using identifiers, not strings, IMO.

many thanks John, now works fine.

I have had messages from the compiler with the following bitmap names:
DELETE, HELP, MENU, i have changed the names, and the compiler has not given anymore messages.
now i will use the numeric identifier.

thanks again,
marzioni
