The following code example generates Windows-based messages in on override of the OnMouseMove method. Every time the mouse moves, or whenever there is a tap, this method generates a Windows-based message with the X and Y mouse coordinate values occupying the WParam and LParam parameters. This code example is part of a larger example provided for the MessageWindow class.
Dim msg As Microsoft.WindowsCE.Forms.Message = _
Microsoft.WindowsCE.Forms.Message.Create(MsgWin.Hwnd, _
MsgWindow.WM_CUSTOMMSG, New IntPtr(e.X), New IntPtr(e.Y))
MessageWindow.SendMessage(msg)
Message msg = Message.Create(MsgWin.Hwnd,
MsgWindow.WM_CUSTOMMSG,
(IntPtr)e.X,
(IntPtr)e.Y);
MessageWindow.SendMessage(ref msg);
