Rutin hem 32 hem de 64 bit sistemlerde çalıştığından emin olmak için biraz fazladan kontrol yapmanız gerekir. Bunlar gibi durumlarda, çerçevenin pinvokları nasıl uyguladığına bakmak için reflektör kullanıyorum. Özellikle, System.Windows.Forms.SafeNativeMethods ve System.Windows.Forms.UnSafeNativeMethods bir göz atın.
Uzantı yöntemlerinden yararlanan kullanıyorum kod aşağıdadır.
'See: System.Windows.Forms.SafeNativeMethods.SetWindowPos
<DllImport("user32.dll", CharSet:=CharSet.Auto, ExactSpelling:=True)> _
Private Function SetWindowPos(ByVal hWnd As HandleRef, ByVal hWndInsertAfter As HandleRef, ByVal x As Integer, ByVal y As Integer, ByVal cx As Integer, ByVal cy As Integer, ByVal flags As Integer) As Boolean

End Function

If (IntPtr.Size = 4) Then
