Registered messages in C#

[Bob Moore]

I have to interface with an unmanaged DLL. This involves passing a
registered message value into the DLL, and it posting the registered
message back to my app's window when an event occurs. But I've
searched the web all morning and can't find _anything_ on handling
registered messages in C# Winforms apps.

Can anyone point me in the right direction?

"registered message" = Win32 message registered by 'RegisterWindowMessage'?

You can override the form's 'WndProc' method and handle the message there.
In addition, take a look at the 'IMessageFilter' interface.
