Hi Bob,
Chris has given some idea on this issue, and I'd like to expand the
solution.
In Win32, we often handle the messages in wndproc , Now in WinForm the
WndProc still exists, every class derived from Control class have a
protected method named WndProc, you can override this method to handle your
own message of that control. Here is some snippet to show how to do this.
<code>
protected override void WndProc(ref Message m)
{
const int WM_USER = 0x0400;
If(m.Msg == WM_USER)
{
//call your handler here.
}
base.WndProc(ref m);
}
</code>
Also if you need to handle the message before it is dispatched, you may
implement the IMessageFilter interface to do this job, You can add a
MessageFilter to the MessageLoop by the Application.AddMessageFilter
method, to get more information on and sample code on this topic you may
take a look at the this link:
<Application.AddMessageFilter Method>

Does this answer your problem?
