Using Application.Run () without a form

[mike2036]

Is it possible to put a VB.NET application in a message loop without a form?
From what I've read the method Application.Run () (parameterless) allows for
this...but how do you define the message loop handler that's the equivalent
of WndProc for an application that does not have a form? Unfortunately
Application.Run (new form()) makes the form visible so using a dummy form
doesn't work here. Thanks in advance for any help.

Check out 'Application.Ad dMessageFilter' in the documentation.

Hi Herfried,

Thanks for the reply. Do I still need a hidden form using a message filter,
since I need to pass a handle to external app's to be signaled with messages?
Or can I get the application handle somehow from a formless app?

If the other application requires a window handle, you'll have to create a
window.
