Ok. To recompile, simply open the vbp file. You will probably find that you get warning messages about how you can't find various files that the program needs. If you do, continue loading anyway when it asks you. Then, go in and manually add your code files (go to the project explorer, right click on the name of your project, select Add, and add each code file into your project). Once you're done, save. After this, just go to the File menu, and about 2/3 of the way down, you'll see a "make FileName.ocx", where FileName is the name of your control.
Now, this assumes a few things. If it doesn't work, post back again and we'll strip out a few more things.
