Windows Service and application.DoEvents()

[Wolfgang Kutschera]

Greeting folks!

This question has been asked before, but unfortunately never really
been answeared. I would appreciate to get any clous on how to solve
the problem:

I am writing a windows service that interacts with the desktop. (It
shows a status dialog if a user is currently logged on.) To get this
dialog shown correctly I need to have something like an
application.doevents() call in my service. Is there anything like that
for use with such services?

I would appreciate any help.

If you're service is a background service then it should be ok. How often &
for how long does the service interact with the Desktop?

You could separate the UI from the service and then let the UI application
communicate with the service using events, remoting, sockets, ... This
would avoid the problems introduced by services which interact with the
desktop.

Hi!

The service mainly does it's work within the first two minutes after
it is being started. The interaction should take place during this
period of time. Currently if a user is logged on the windows appears
on the users screen, but never gets the time to handle the draw event.
(Means the frame is visible, the content isn't...)
