'Option Explicit
Private Sub Form_Load()

End Sub

Private Sub Form_Unload(Cancel As Integer)
SetHotkey 1, "", "Del"
End Sub

Private Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long
Private Declare Function GetWindowLong Lib "user32" Alias "GetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long) As Long
