Message Structure

Implements a Windows-based message.

Namespace: Microsoft.WindowsCE.Forms
Assembly: Microsoft.WindowsCE.Forms (in microsoft.windowsce.forms.dll)

public struct Message
public final class Message extends ValueType
Not applicable.

The Message structure wraps messages that Windows sends. You can use this structure to wrap a message and assign it to the window procedure to be dispatched.

You cannot directly create the Message structure. To create a Message structure, use the Create method. For efficiency, the Message structure uses any existing structures from its pool instead of creating an instance of a new one.

The following code example creates and sends a Windows-based 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.

Dim msg As Message = 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); 

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
