Where is Message defined in .Net, using the Compact Framework?

Question

Should be an easy question, so don't all pile on -

I'm trying to override WndProc like this:

using System;
using System.Collections.Generic;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.IO;

snip...

public class GTextBox : TextBox
{
    protected override void WndProc(ref Message m)

and I get this error:

error CS0246: The type or namespace name 'Message' could not be found (are you missing a using directive or an assembly reference?)

I've poked around a little but I don't see how to find out where Message is defined? Any hints?

Update: "using System.Windows.Forms" is in the file, and I have checked the DLL reference. Hmm... probably time to re-boot for good luck?

Update 2: My Bad! - I am using the Compact Framework, and it does not allow direct access to the Message structure. Ouch - should have put that in my original question

Update 3: Excellent article on CF and WndProc handling http://msdn.microsoft.com/en-us/magazine/cc188736.aspx

Answer 1

The Message struct is in the System.Windows.Forms namespace and assembly.

Answer 2

I believe it's "System.Windows.Forms.Message." I'm not sure why you're getting that error, it looks like you're "using System.Windows.Forms;".

Maybe the DLL reference got deleted?

Answer 3

Took a bit of a creative google search but:

Answer 4

Thanks for all the help - I just realized the problem is I am using the Compact Framework, targeting Windows Mobile, and there is no direct access to Message.

Answer 5

It's publicly available in the Microsoft.WindowsCE.Forms namespace. You need to add a reference to the assembly.
