Help a newbie with Visual Studio

Hello, it's my first time making keygens and I'm almost finished with it but I'm stuck with a function that I want done. I have the keygen showing a progress bar once i hit generate but I would like it to show the key after the progress bar is finished. I have no idea how to get this to show. I tried throwing this in:
after the timer for the progress bar, but that now only makes the progress bar show without a key. Can anyone help me what I would need to insert for this to work properly? I know I don't really need the progress bar for such a keygen, but it would be good for me to know in the future.

Just a quick one using your code, you could do this in progressbar1 value changed:

Dim Key As Integer

If ProgressBar1.Value = 100 Then
Key = Int(Rnd() * 3)
msgbox(Key)
end if
