!!HELP with resource script

I added the resource script (RC file= to the DEV C++ Project files.
The project compiles OK, but FindResource cannot find the resource.
The resource file is OK, the resource type is IMA and the resource name is

IMA_1. (DEV C++ 5, W Vista Home Ed)

I guess the resource script is not getting compiled at all.
I would prefer to add a .RES file to the Dev C++ Project.
How can do that?

Thanks in advance.

#include <iostream>
#include <stdlib.h>

using namespace std;

int main(int argc, char *argv[])
{
 HRSRC   hRsrc;
 HGLOBAL hResource;
 DWORD   dwSize;
 int   hfFile;
 
 hRsrc = FindResource(NULL, TEXT("IMA_1"),TEXT("IMA"));

 if (hRsrc) 
 {
     hResource = LoadResource(NULL, hRsrc);
     dwSize = SizeofResource(NULL, hRsrc);
    
     char *pdata = (char *)LockResource(hResource);
     
     hfFile = _lopen("image.jpg",OF_WRITE);
     _lwrite(hfFile, pdata, dwSize);
     _lclose(hfFile);
 }
 else
   cout << "Failure";
	
  return 0;
}
