Hi,
I'm using VB.Net and writing an NT service that runs in the system
account in the background with no interaction with the desktop.
I'm running it on XP Pro.
I'd like to get the URL of any Internet Explorer process a logged in
user is running.
I can get a list of process IDs and from that use
System.Diagnost ics.Process.Get ProcessById to get information about the
processes.
What I had planned to do was get the hWnd from the process with
process.MainWin dowHandle, but this seems to always return 0. I'm
guessing that this is something to do with the service running in the
background.
So then I tried a different approach with the following code:
objShell = CreateObject("S hell.Applicatio n")
If Not objShell Is Nothing Then
For Each objIE In objShell.Window s
If Microsoft.Visua lBasic.Left(obj IE.LocationURL, 4)
= "http" Then
URLString &= objIE.LocationU RL & " "
End If
Next
End If
This works from a standard desktop app and gets a list of the URLs in
all open IEs, but when I run it as part of the service, the first line
fails with "Class Not Registered". Again I'm guessing that this is
because I'm running in the background.
So now I'm at a dead end. I can get the processID of the iexplore
process, but can't get the windows handle and therefore I can't get any
further... but... well it's there somewhere! There has to be a way
to get it!
I would really appreciate any light that could be shed on this problem.

Have you got your service set to be able to interact with the desktop? It's
an option somewhere but my experience of services is limited so you'll need
to Google if you can't find it :)

Mr B.
I've set it not to interact with the desktop. I'm wanting it to run in
the background.
Hmmm... here's a question then... What are the disadvantages of making
it interact with the desktop?
Mr B.
But surely you want it to interact with the desktop to be able to grab the
window handles? It can still run in the background, my impression was just
that allowing the interaction meant the service could "see" the logged in
users' desktops. However, as I said in my original reply, this might be
incorrect. Unfortunately I can't advise you on this as I haven't really
worked with services.

Thanks Jevon
Sorry for the long time not replying to this. I'll have a look into it
and try to see if it works with interact with desktop enabled. Been a
bit busy lately and this is a "spare time" project.
What you are saying makes sense. I think I'm going to have to google
to find out what the difference is, but if it is as you say, then I
can't understand the need for a setting that disables interaction with
the desktop... If the only thing that the setting does is stop a
service from doing something (rather than enabling it to do something
else), then what's the point in including the setting? Unless it's a
security thing... ho hum... I think it's time to google :-)
Thanks for your help. If I ever figure out my problem (or find out
what the point of the interact setting is), then I'll write back and
let you know.

I'm not sure if it's already been mentioned... or would even help but...

How can I get all the titles of all openning windows? I found a API in

I'm trying to get (or set) the focus on an external window but to no avail. I've imported the "GetActiveWindow" and "GetFocus" from the user32.dll but those 2 functions seem to only work for windows my application owns... I can get the hWnd of the process I want to check/set focus on. Any help would be greatly appresated.
Just to be a little more clear, say NotePad is up; I'm trying to make my program set focus to the opened Notepad...

I need to know the position (X, Y cohordinates) of the caret. I'm
