Creating my own ActiveX control

I am just starting a project which requires me to create my own ActiveX control. I created a few test controls to see how they work and they worked successfully, at this point, I deleted those files. I noticed, however, when I go to add another ActiveX, the names of those controls are still listed in the components window. If I try and select this, it gives me and error which is to be expected because I deleted the .ocx My question is why are these still there, and if Im creating a complicated ActiveX in the future, is there certain steps that I should take when compiling and testing the control? Any advice would be appreciated. Thank You

But of course!

Dave Sell answered to you! There are some values of your controls to the registry! Delete them if the activex controls don't exists any more!
