>I need to determine if a form is to continue load based upon a specific condition. What I need to know is how to STOP a form before it SHOWs.

I am not sure if this is the best way to handle this, but you could set a ReadOnly field in the form's constructor method:

Dim myForm As MyFormClass

If myForm.IsOKToShow Then
   myForm.Show()
End If

Class MyFormClass
   Inherits System.Windows.Forms.Form

   Public ReadOnly IsOKToShow As Boolean

   Public Sub New()
      If (Logic here to determine whether or not to show the form) Then
         Me.IsOKToShow = True
      Else
         Me.IsOKToShow = False
      End If
     End Sub

End Class
