Ok, it's a dll written in straight C and it wasn't built on my computer. I tried registering the dll (using regsvr32) but I got the "no entry point" message. I almost always get this message to a point that I think that my "regsvr32" program is corrupted. So, I wouldn't mind the message.

Now, what do you mean when you say that I need to set a reference to the componenent?

Thanks again, Stephane.
