Hi everyone,

I have NT service from which I try to display window form.
This form is created in sub New.
In servise I implemented OnCustomCommand handle, when I wait for command 129
and for this command I try to do form.Show() but I can't see this window :-(
I checked by filelog - form_load is running after send command.

Is possible to display window by that way?
If yes please tell me how.
Or maybe somebody has another idea for this problem

Regards

Hi,

I feel I should point out that it's very bad practice to do this anyway, and
in future versions of Windows (or potentially even service packs) Microsoft
may well prevent this behaviour. Having a service with any kind of GUI is a
big security hole, as that form essentially has all the privileges of the
user account the service is configured to run as - potentially SYSTEM, which
has more powers than even the Administrator.

My advice would be to partition your solution into two projects - one
service, one forms app. Have the forms app interact with the service using
remoting. Much safer :-)

Regards,

Agreed.

I want to have access to event of my service this is why I think about form
from service.
How can I get access to service event by external form with use of remoting
technic?
(I don't use this never before)

Do you mean that you want to be able to show service state somehow? Like
running, or stopping?

Try building a separate application that sits in the system tray and
monitors the service state using the local SCM interface.

Something like the service control manager form SQL server.
