Well, you can use API to make hotkeys. There's an API specifically for global hotkeys, but I find it harder to use than the getkeystate API checking every few milliseconds for the button press.

Found one URL with what appears to be a good example.

Look here:
http://www.youtube.com/watch?v=Xr_cwdczOzo

Also test this:
vb

Private Sub Form_Load() 
KeyPreview = True 
End Sub

Then for the hotkey
vb

If KeyCode = vbKeyF1 then  Command1_Click

There's no reason to give up, it's really very simple.

Put this line in the general declarations:
vb
Private Declare Function GetAsyncKeyState Lib "User32" (ByVal vKey As Long) As Integer


Make a timer and make it's interval one millisecond, and in the timer put this code:

This first line is just used to refresh the API. If you don't put this line you will experience problems with the hotkey.
vb
GetAsyncKeyState KeyCode


Then below that, put this code:

vb
If GetAsyncKeyState(KeyCode) Then
    'HotKey pressed, put your code here
End If



And that will work. But this code isn't perfect. The hotkey will be detected over and over and execute the code over and over, something you probably don't want to happen. So, put in some extra code to check if the key has been released or not, and if it hasn't, don't execute the code.

Considering the rate at which people don't follow up to their questions, I decided not to risk it not being solved and went straight for what he was probably asking for.
