Creating own Control Class - Help!!

Hi, I want to make a control and define its classname. Know how you can find a window by its classname? I want to be able to find a control of mine that resides in a compiled exe by using its classname and then send text to it. How would I make a control and define its classname so that I could do this?

The reason is that I want to make a dynamic lookup executable to which I will pass values from another compiled executable.

Thanks so much,
Wade

I made a small usercontrol and compiled it as an ocx. When I add it to another project and run the app, the usercontrol returns a classname of ThunderRT6UserControlDC. I don't see a way to rename this.

Any ideas on this? Or how to pass the value and then read it from the other app?

Thanks,
Wade
