Something like this would work:
Const WM_MOVE As Integer = &H3
Const WM_SIZE As Integer = &H5
Const WM_WINDOWPOSCHANGED As Integer = &H47
Protected Overrides Sub WndProc(ByRef m As Message)
MyBase.WndProc(m)
Select Case m.Msg
Case WM_MOVE, WM_SIZE, WM_WINDOWPOSCHANGED
If Me.WindowState <> FormWindowState.Minimized Then
'do something
End If
End Select
End Sub
