Since you're trying to execute a function that can take some time, I'd advise you to make use of threading. In .NET there's a BackgroundWorker component which is excellent for performing tasks asynchronous.

On button click, invoke the BackgroundWorker like this:

if not bgwWorker.IsBusy then
   btnGo.enabled = false
   bgwWorker.RunWorkerAsync()
end if 

And use the completed event to enable the button again:

Private Sub bgwWorker_DoWork(ByVal sender As System.Object, _
                 ByVal e As System.ComponentModel.DoWorkEventArgs) _
                 Handles bgwWorker.DoWork
' Do your things    
End Sub

Private Sub bgwWorker_RunWorkerCompleted(ByVal sender As System.Object, _
                         ByVal e As System.ComponentModel.RunWorkerCompletedEventArgs) _
                         Handles bgwWorker.RunWorkerCompleted
' Called when the BackgroundWorker is completed.
btnGo.enabled = true
End Sub

In the example above, I've used bgwWorker as the instance of a BackgroundWorker.
