Resource files

Hi all,

i know how to make dll, and how to use functions and procedures in it, but i want to make dll ONLY with resources (like bitmaps, icons, waw's etc.).
I know how to make dll, but i don't know how to USE those resources in it..
Please help

You simply need to load it just the way you do, and pass the handle LoadLibrary() to the LoadBitmap() for example which would load the bitmap from the DLL...

Hi Viktornet,

you think something like that?

procedure TForm1.Button1Click(Sender: TObject);
var
il: THandle;
begin
il:=LoadLibrary('NameOfMyDll.dll');
if il<32 then
begin
ShowMessage(IntToStr(GetLastError()));
end;
Image1.Picture.Icon.Handle:=LoadIcon(il, PChar('3'));
Image2.PictureBitmap.Handle:=LoadBitmap(il, PChar('5'));
FreeLibrary(il);
end;

What i get with this code is:
1. Nothing in those Images :o)
2. Error message when i close an application "Invalid handle to the pointer" ???
Any idea?

So my Q is ...

does NOT work - or am i missing something?

How to load WAW or similar files?
I will increase the points if sombody has a really good answer (like two or three lines of code ;o)

For icons, use:

...Icon.Handle := LoadIcon(il, MAKEINTRESOURCE(3));

For bitmaps, use

bmp.LoadFromResourceID(il, 3);

For waves and the like, do something like this:

var hRes: HRSRC;
gobj: HGLOBAL;
p: Pointer;
begin
hRes := FindResource(il, MAKEINTRESOURCE(3), RT_RCDATA);
gobj := LoadResource(il, hRes);
p := LockResource(gobj);
//p is a pointer to your resource data

...

Barry's got the correct answer. The site he pointed is actually the best resource on the net about resources (forgive the pun!). I have no affiliation to the site he pointed you to, but I just happen to know the guy to created that site (he's a nice fellow, by the way).
The URL Barry gave you is undoubtly a perfect answer to the question. ;)

Just for the drama effect, like those folks that sell stuff on TV.
