Question

I just want a c# application with a hidden main window that will process and respond to window messages.

I can create a form without showing it, and can then call Application.Run() without passing in a form, but how can I hook the created form into the message loop?

Is there another way to go about this?

Thanks in advance for any tips!

Excellent! That link pointed me in the right direction. This seems to work:

        Form f = new Form1();         f.FormBorderStyle = FormBorderStyle.FixedToolWindow;         f.ShowInTaskbar = false;         f.StartPosition = FormStartPosition.Manual;         f.Location = new System.Drawing.Point(-2000, -2000);         f.Size = new System.Drawing.Size(1, 1);         Application.Run(f); 

To keep it from showing up in Alt-Tab, you need it to be a tool window. Unfortunately, this prevents it from starting minimized. But setting the start position to Manual and positioning it offscreen does the trick!
