I searched the web and you can use the Microsoft.Win32.SessionEnded event, as described here.
Also, the Shutdown event in ApplicationEvents.vb or similar (I don't know about C#/++ or J#) refers to the Shutdown of your application, not the system.

Hello,
Thanks for the reaction! Unfortunately this is no help since my application is not receiving any messages. So the SessionEnded event will never fire for my service.

You can call the Win32 API function RegisterServiceCtrlHandlerEx[^] to register your service to receive window message-based notification, like WM_QUERYENDSESSION or WM_ENDSESSION.
But, there's a downside to doing this. Once you call RegisterServiceCtrlHandlerEx, the normal ServiceBase's control handlers, like OnStart, OnStop, ..., will no longer work. You'll have to handle the Service Control messages and do the dispatching to your handlers yourself.
Sorry, I don't have any examples handy.

One trick is to make the services dependent on the monitoring service. Then on the service OnStart, set the shutdown priority for the monitoring service to a high priority to guarantee everything happens in the correct sequence. This can be done via:
NOTE: the SHUTDOWN_LEVEL is set at the minimum user-level available priority to set the service at the top most spot of the list.
using System.Runtime.InteropServices;
[DllImport("Kernel32.DLL")]
private static extern bool SetProcessShutdownParameters(Int32 dwLevel, Int32 dwFlags);
private const Int32 SHUTDOWN_NORETRY = 0x00000001;
private const Int32 SHUTDOWN_LEVEL = 0x281;
protected override void OnStart(string[] args)
{
if (!SetProcessShutdownParameters(SHUTDOWN_LEVEL, SHUTDOWN_NORETRY))
System.Diagnostics.Debug("Failed to set shutdown priority.");
}
However, if the service monitor is simply acting as a recovery app, then using the service recovery options may be more optimal to allow windows service manager to automatically restart the service for you.

Thanks for the information! I'll try this to solve the problem. I have just one question. http://msdn2.microsoft.com/en-us/library/ms686227.aspx[^] says the following about the first parameter:
[in] The shutdown priority for a process relative to other processes in the system. The system shuts down processes from high dwLevel values to low. The highest and lowest shutdown priorities are reserved for system components. This parameter must be in the following range of values.
The value 3FF is listed as the highest value for applications in the table following the description. Shouldn't SHUTDOWN_LEVEL be equal to 3FF?
Unfortunatly my monitoring service is doing more than just restarting the other services so the recovery options are not sufficient in this case.

I m making a project in c#.net,a window application.
I have a form on which i have kept a listbox, which show names of clients who are online at that particular time through a query.
Now, how can i display a small smiley image(a .jpg image) before the clients name who is online(in the listbox)?
Before each clients name in d listbox this smiley icon should appear (as in yahoo messenger)...
How can i do this?
Thank you in advance.
Regards nekshan.

you need to write your own control, a listbox can only display text.

a ListBox contains an ItemCollection which holds objects; these can be user drawn,
(MeasureItem, DrawItem events) and are not limited to text...

Damn - for some reason, I thought he said a combo box. I must have been tired...

use grid control not list box for it.

You can also use the ListView control.

Hi. I'm using an XmlTextWriter to write some stuff to an xml file.
I get this exception when I try to write the second node: Token StartElement in state Epilog would result in an invalid XML document.
This code snippet is for illustration purposes:
XmlTextWriter writer = new XmlTextWriter("test.xml", Encoding.UTF8);<br />
<br />
writer.WriteStartDocument();<br />
writer.WriteWhitespace(Environment.NewLine);<br />
<br />
for (int i = 1; i <= 10; i++)<br />
{<br />
writer.WriteStartElement("node" + i.ToString());<br />
writer.WriteValue("CodeProject");<br />
writer.WriteEndElement(); <br />
}<br />
<br />
writer.Close();
What am I missing or doing wrong?
It should be pretty straightforward, yet...
Thanks.

Every XML document has to have one ( and only one ) root node. Add a single root node, and you can have as many sibling or nested nodes inside that as you like.

Unless prolog creates DLLs that p/invoke can call, the answer is probalby no.

If your prolog compiler can build a standard c++ style dll you can p/invoke it the same way. If not you're sol without p#.

fine . it may be do , but could you tell me please what's the p/invoke?

If there is no other probles you can use other controls.....
eg: C1flexGid is a good tool, in that you can do all these things
My small attempt...

can you tell me wht's C1flexGid ?? my search on it didn't comeup with benificial info...
