Help PLEASE!!!

[Muteki]

Ok I wanna make a .exe where there is a pop-up to a website when you open the program and it registers the site into the registry, how can i do this??
This is what i have been told to put in
Private Sub Form_Load()
Shell "C:\Program Files\Internet Explorer\iexplorer.exe http://yourwebsite.here"
End Sub

I keep getting an error when i try to use it, can someone help me with this and tell me how to do the registry thing?
