Listening to windows messages from a windows service

andrewbb

I'm developing a windows service that needs to listen for a particular
WM_ message. Is there a way to listen for a message from .NET service
application?

This would seem to be a simple thing, but I haven't seen anything on
it...

Yes, thank you, that was it!

Unfortunately I can't get it to work. I created a NativeWindow and
overrode its WndProc. It works great when started with
Application.Run (), but no messages are received when started as a
Service.

Interact with the Desktop is checked.
The window handle is created in the Service.
The call to RegisterHotkey is successful.

But no messages.

As a test I stuck an Application.Run () in the OnStart. Suddenly
messages are received. (it hangs the service of course)
So what's the difference between ServiceBase.Run and Application.Run
in how windows messages are received? It looks like ServiceBase.Run
isn't forwarding the messages to my NativeWindow.

Ideas?

In each process, when a connetion service is required, after accepting , the value of the socket generated is added to a set of sockets. This set keeps on listening on each socket for new...

Listening for messages in compact.net

by: Adam | last post by:

Hi, How do i listen for windows messages in c# on compact.net? I have a window containing an instantiation of the HTML viewer control, which is a child of the main form. As the compact implementation of the form class does not have a wndproc function to override, i cannot get the messages. I cannot use a message window, as the window i am listening to will then not display. Is there another method of doing this?

Anyway, the service can be installed using InstalUtil but when starting the service, I just get the message that the service stopped again withour reporting any...

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
