クラスとウィンドウ（.net framework）
・何年も前に広まってた手法ですが覚書。。。
クラス内でNativeWindowを派生して、見えないウィンドウを作成するサンプル
class.vb
Namespace myNamespace
Public Class myClass
Inherits NativeWindow
Public Sub New()
MyBase.New()
Dim cp As New CreateParams
cp.X = 0
cp.Y = 0
cp.Height = 0
cp.Width = 0
cp.Style = WS_EX_TOOLWINDOW Or WS_POPUP Or WS_VISIBLE Or WS_SYSMENU Or WS_MAXIMIZEBOX
Me.CreateHandle(cp)
End Sub
Protected Overrides Sub Finalize()
Me.DestroyHandle()
End Sub
Protected Overrides Sub WndProc(ByRef WMSG As Message)
Select Case (WMSG.Msg)
Case WM_USER_XXX
Dim myWParam = WMSG.WParam.ToInt32
Dim myLParam = WMSG.LParam.ToInt32
End Select
MyBase.WndProc(WMSG)
End Sub
End Class
End Namespace
