How can I trap all mouse events on a control?

Question

I need to capture all mouse events on a .NET's WebBrowser, process them and prevent the WebBrowser from getting them. Is there any way to achieve this? I wonder if there is any way I can handle mouse events if the control is disabled.

You'll have to override WndProc() to intercept the mouse messages. Like this:

using System;
using System.Windows.Forms;

class MyBrowser : WebBrowser {
    protected override void WndProc(ref Message m) {
        if (m.Msg >= 0x200 && m.Msg <= 0x20a) {
            // Handle mouse messages
            //...
        }
        else base.WndProc(ref m);
    }
}
