Listening to OS messages in C#

Is there any methods in C# similar to WndProc method to listen to the OS messages.I cant use WndProc because,my class is neither Form nor Inherited from Control(Its DLL)

protected override void WndProc(ref System.Windows.Forms.Message m)
    {
        switch (m.Msg)
        {
            // listen os messages


            // Ueye Message
            case uEye.IS_UEYE_MESSAGE:
                //fetch frame
                break;
        }
        base.WndPr开发者_Python百科oc(ref m);
    }

WMI will do if you want to listen for specific messages. I once had a project (see comment on question) that listened for removeable USB drives and WMI worked just fine.

You can use interop as well but I find it messy but YMMV.

The standard approach to receiving windows messages in the absence of a visible window is to create a non-visible window to receive messages.

You should use Windows.Interop

to have access to Win API

It seems to be possible to override WndProc, but I haven't tried it myself!

If you have a Form (visible or otherwise), look at Form.WndProc.

If not, you could try using Application.AddMessageFilter to add a message filter to monitor Windows messages.
