Your only recourse is to add debug/logging code to the screensaver to find out what is going on when it runs for real.

Great. Format your box, or throw it away - SYSTEM is a limited account for a reason.
Another scenario where this would fail would be if the screensaver (or the OS) opens a new desktop. You may not have enumerate-priviliges there, and it may not have any open windows.
Is there error-logging included in the code? Iow, are you sure there is no exception thrown that terminates the execution of the screensaver?

As Eddy said, I think your screensaver is running in a different desktop:
By default, there are three desktops in the interactive window station: Default, ScreenSaver, and Winlogon.
...
Whenever a secure screen saver activates, the system automatically switches to the ScreenSaver desktop, which protects the processes on the default desktop from unauthorized users.
According to a comment on this 2006 blog post from Raymond Chen[^], if you tick the "on resume display log-on screen" option, your screensaver will be run in "secure" mode.

Thank you for all the responses.
I don't have "on resume display log-on screen" checked. However it seems like it might be something like a separate desktop (I never knew!)
.
I re-coded the screensaver so that when it runs it only fills half of the screen. The idea was so I can get a look at the task manager and see what user/owner the program was running under (because I can't usually see it when it is running obviously).
Some observations:
- the screensaver runs correctly when activated by the "preview" button in the screen saver management dialog. It gets the enumeration of windows, and it only fills half the screen and I can read the task manager.
- when triggered by the OS after being idle, the program correctly only fills half of the screen but the rest is black and the rest of the desktop is gone.
So how can I get this desktop to be able to see what programs are running ? It is able to read from the HDD and other parts of screensaver that work.
This has worked for years on Windows 7 and 8, and I am only an intermediate C# coder. Frustrating.

That's because when the screen saver is launched from that dialog, it's running as YOU, not the system.

That would be because you're looking as the secured desktop screen savers run under.

You don't. That desktop hjas been secured to the point where anything running under it cannot see the processes running under a different desktop, namely the users desktop logged into the console.

Yes, a screen saver running on the screen saver desktop still has access to other system resources, such as the local drives.

Why even bother with a "screen saver"?
Any program running "full-screen" (or not) will meet your requirements (based on your description).

Gerry, you might have a good point there. The program is sort of our family dashboard that runs on the kitchen computer. The idea being when someone is not using the computer it will show the family calendar (which we live off of), the weather, random photos, and if the music player is playing it will show the current playing album (hence connecting to another program).
I guess I could just write my own small launcher program that will launch the dashboard based on win32.GetIdleTime instead of relying on Windoze screensaver.
Thanks for the brain-jog!

Yes!
Program can run in the background and task bar on startup. I've used keyboard and mouse hooks to monitor activity.

Hi all, suppose I've queried a data source and let's say 10 thousand records are supposed to come back. If I want to pause the reception of the data at a particular record and then resume the data reception on button click is there a way to do this using C#? Thanks in advance.
|
|
|
|
|
Unless you're using a DataReader, no there isn't.
Unless you doing processing on all those records, returning 10,000 records to display them is just stupid. Use paging instead so you're not sitting around waiting for that many records to load and be bound to a visual control.
|
|
|
|
|
Besides "paging", the other keyword here is "virtualization" (often used in the context of list and grid controls)

I have this windows service application installed on my windows server.
It's job is to check a specific table from sql database every 5 minutes and send me a notification via email when the table has new records inserted on it. My windows service is set to start automatically however, when the server is restarted, the service wont run until I logged in.
Long story short, what i want is to start my windows service automatically even if i don't login.
I want it to run when my windows server is on logon screen after restart.
Thanks to anyone who can help me.. I really need this and tried to google for a day and no luck for me.

I think you need to set it up to run under the Windows account rather than your own.
|
|
|
|

Thanks for this. Tried to set up with Network Service account and works like a charm.

To add to what Eddy said: If your service depends on other services, you may want to use Automatic (delayed start).
Arguing with a woman is like reading the Software License Agreement. In the end, you ignore everything and click "I agree".

Im already using Automatic (Delayed Start) how ever it seems that i need to set it up with other account rather my own local account so the service can run automatically on start up.
|
|
|
|
|
Sounds a bit odd. If the service is set to start automatically, then firstly what account is it running under (2nd page of options in the SCM if I remember rightly)?
Second question - is there anything showing as an error in the eventlog (eventvwr from start)?

I am trying for a long..that when three or more players are connected to each other and any one of them clicks on the play button then it should be start on all others clients screen.Please help me.. that how can i do that.
|

Not a good idea.
And you would at least need to provide a lot more background information.
I also suggest that you look at Jackbox games to see what they have -- it might be similar to what you desire.

Here is the screenshot of the datagridview that I have
[^]
here's the code -
int i = 0;
foreach(XmlNode node in doc.SelectNodes(query))
{
row = results.NewRow();
XmlNode Element = (XmlNode)node;
foreach (XmlNode node1 in Element)
{
XmlNode Element1 = (XmlNode)node1;
results.Columns.Add(Element1.Name, typeof(string));
}
foreach (XmlNode node2 in Element)
{
XmlNode Element2 = (XmlNode)node2;
foreach (XmlNode node3 in Element2)
{
XmlNode Element3 = (XmlNode)node3;
foreach (XmlNode node4 in Element3)
{
XmlNode Element4 = (XmlNode)node4;
if (Element4.Name == "intensity")
{
row[i] = Element4.InnerText.ToString();
results.Rows.Add(row);
row = results.NewRow();
}
}
}
i++;
}
}
return results;
problem is that the datagridview is not formatting the text correctly, as you can see it keeps creating a new row for each result set for a color.. I need it to show correctly?
thanks
Craig.

What is in query and can you share the declarations for row and results.
Also - shortening the amount of XML we have to copy would be nice.
When you say "show it correctly" what do you mean by "correctly"?
