>I have an urge to use the IE browser control 10 times and the FastWrite GIF89 DLL control (from the files section) 15 times in a few different forms. Am I in danger of using an enormous amount of memory because I am calling same DLLs multiple times? Or because I am using an .ocx and .dll I am OK they just get placed in memory once and reused?

They will only be loaded once.
