Number of files in a .RES

[bobbie100]

I am loading all the images from a .RES file by ID number using:

  for I := 0 to NUM_RES_BMP - 1 do
    FBmps[I].LoadFromResourceID(HInstance, I);

At the moment I have the separate constant (NUM_RES_BMP ) defining the number bitmaps in the .RES.

Does anyone know how to get the number of files in a .RES file, so I can get rid of this separate constant?
OR
Do I have to resort to the alternative approach of reading the files in one at a time and catching the exception when there are no more files? (I don't like relying on exceptions as part of the normal program operation).

Many thanks
Bob

I use: (Stripped down version)

   Temp := PChar( {Name minus .dll part} );
   LibraryID := LoadLibrary(Temp); // load resource-dll
   If LibraryID <> 0 then
   begin
      Repeat
         inc(PicID);
         If LoadString(LibraryID,PicID,strTemp,sizeof(strTemp)) = 0 then Fail := True;
         //Do stuff related to string
      Until Fail;
   end;

Note that I'm loading strings with this, but it should work for most others.

LoadString

loads the string with the name

PicID

in the library with handle

LibraryID

into the variable called

strTemp

with size

sizeof(strTemp)

and returns a 0 when it can't do it anymore.
