Examples

The following code example creates and sends a Windows message with the identifier of WM_CUSTOMMSG. The message is given the handle of a message window, named MsgWin, to which it sends the messages. The message contains values for the WParam and LParam parameters, which in this example are current x and y mouse coordinates as obtained from MouseEventArgs, e, in an OnMouseMove method.

This code example is part of a larger example provided for the MessageWindow component.

[Visual Basic]

Dim msg As Message = Message.Create(MsgWin.Hwnd, 
    MsgWindow.WM_CUSTOMMSG, New IntPtr(e.X), New IntPtr(e.Y))
MessageWindow.SendMessage(msg)

[C#]

Message msg = Message.Create(MsgWin.Hwnd, 
    MsgWindow.WM_CUSTOMMSG, (IntPtr)e.X, (IntPtr)e.Y);
MessageWindow.SendMessage(ref msg);
