I know how to capture a keypress for a windows application, but how would I
go about doing it for a windows service?
Rather than having a form in focus all the time, I would prefer to have
something running in the background. There are option such as having the
form invisible (opacity set to zero) and settings it's location as -200, -200
so that it isn't on the screen, but this isn't the ideal solution. 4 13094
What is the effect you are trying to achieve. You cannot show a form from a
service but you might not want a service, you might be interested in a
notfify icon

Basically I am trying to create a crude keylogger application. I didn't want
to show a form from the Windows service (using a Windows form was an
alternative option, and although it works, it is not the ideal way to capture
all key strokes).
I would rather have the windows service running in the background from the
moment the computer starts to the moment is closes down.
I realise that there are free keyloggers available on the web but I would
like to add my own functionality.

Ciaran,
A service in this case is not the correct solution. A service is not
aware of the currently logged on session, as there could be no current
session, or multiple sessions.
What you want to do is have a program run when the user logs on, and
then have that insert a windows hook which will capture the keystrokes.
Hope this helps.

Goodluck with writing your keylogger. The windows api for this is
hellish (also it only runs in unmanaged code)... personally I think
you should buy a commercial application. However, follow that link it
has some great examples of viewing keypress events in C# ( and
suppressing them ). Also capturing CTRL+ALT+DEL and passwords is a
whole different ballgame but that link does support it. http://www.dwinlock.kassl.de/

Hi guys,
I have a little problem. I have a class that uses Windows API to capture a
snapshot of the screen. I have this class in a library that I include in my
projects.
When I try to use this class in a windows service, the snapshot comes up as
a black screen. Any idea why? or how do I get around it?
The class works fine if I use it in a regular windows forms application.

What is the best way that anyone has found to capture errors inside a

to a file while it's running. Has anyone figured out any good ways to do
this type of run-time error capturing?

It works great! I found the code in google. But when I create a windows

Is something not available when running as a service? Thanks!!!

So the form opened and run, but windows was already in the "logoff" screen

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. 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,...
