Add and Remove your program to the Add/Remove Programs and Run at Startup lists!! (SMALL CLASS FILE)

Description

Allows you to easily add your program to the Add/Remove programs list, and also add your program to the Run registry key so it starts every time Windows starts!

I didn't see code that adds to the Add/Remove Programs bit here, so I made it myself! Though I find the basic registry routines here, I did Enum one of the arguments to make calling them faster!

Please Vote!

More Info

ProgramName and EXE file Paths are needed to set the Uninstall File or File to run at startup

You need to have a

Dim VarAddRemove as New AddRemove

in the Declarations area, and a

Set VarAddRemove = New AddRemove

in the Form_Load event or Sub Main()

Returns Nothing.

Dangerous to mess with registry keys!
