Is it possible to copy a DLL into my own executable using the IDE only for 
exporting it after in my program? For example, I create an executable Test.exe and 
in the IDE I want to attach a resource that contains the DLL. And when my program 
is running I can export this resource to put a file on my hard disk. Is there a way 
to do that?

Answer:

Create a file called "mydllres.rc". Edit it and insert the line MYDLL RT_RCDATA 
"Mydll.dll". Then call the Borland compiler for resouces (you may need to adjust 
the paths) with BRCC32 mydllres.rc .

This will produce a output file called mydllres.res. Under the implementation 
header in the main unit add the following: {$R mydllres.res}. This will add the 
resource to the project.

The following procedure will save it to a file:

1   procedure savedll;
2   var
3     myres: TResourceStream;
4   begin
5     myres := TResourceStream.Create(hInstance, PChar('MYDLL'), RT_RCDATA);
6     myres.SaveToFile(ExtractFilepath(Application.exename) + 'mydll.dll');
7     myres.destroy;
8   end;
