How do I add a control from another folder outside of vb?

Question

I have a scroller control that is in a folder at another part of the hard drive & I need to intergrate it into vb. I tried the add user control but it has no option to browse other areas for files. I also tried add existing item & it let me add the control file but I couldn't put it in the toolbox where I needed it. It put it in the solution explorer. I don't know if you can get it from the sol explorer to the toolbox or not. If someone knows how to do this, let me know........ Thanks, Joe
