Hi,
I have a C# windows application, say, Launcher, which is started with a privileged user’s credential. Can someone pls suggest how would I be able to capture the logoff event from the Launcher application when a user (not the privileged user) logs off or shuts down from windows, using C#? It would be great if the solution could work in both desktop and terminal server environments.
Regards

You could try the SystemEvents.SessionEnding event, but I'm not sure whether it is invoked for any user or only the one running the application.

As you rightly doubt, SystemEvents.SessionEnding does not work if application is running with another (privileged) user's credential.

What I've done is create a DLL which when added to the registry, logs the log on and log off events. The information to do this is in the platform SDK documentation under WLX. Please note that you do not have to write a replacement for GINA to get this to work.

Hello everyone,
I went thru the article Assemblies: locating, binding and deploying written by Mr. Cohen Shwartz Oren. It is indeed informatory and useful. But i have a problem in C# assemblies. I developed a dll and strong named it. Now i want to use it in an application in another machine. So i wrote the app.config file and given the codebase in that....but the applicaition searches the local directories and the machine.config file and it is not using the path given in codebase. i tried doing it from an application in the same machine also changing the location of dll. but its not working. i think the app.config file is not at all checked.can u pls help me...
the following is my xml code:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentassembly>
<assemblyIdentity name="lib"
publicKeyToken="707ce16eaddaa550"
culture="neutral" />
<codeBase version="1.0.2622.27241"
href="file:///mca-oa2\beuls\c#\lib\lib\bin\Debug\lib.dll"/>
</dependentassembly>
</runtime>
</configuration>
Any help is greatly appreciated.
Thx.

i am also adding the details from the JIT debugger...hope it is more useful... the prob i think is that the machine.config file is searched instead of locating app.config file...

Hello everyone,
I have created a DVD Player windows application using C#. I am trying to get the Name of the DVD and display it the application. I am currently using the following code to get the name of the Disc:
SelectQuery query = new SelectQuery( "select * from win32_logicaldisk where drivetype=5" );
ManagementObjectSearcher searcher = new ManagementObjectSearcher(query);
foreach( ManagementObject mo in searcher.Get() )
{
// If both properties are null I suppose there's no CD
if( ( mo["volumename"] != null ) || ( mo["volumeserialnumber"] != null ) )
{
MessageBox.Show(mo["volumename"].ToString());
MessageBox.Show(mo["volumeserialnumber"].ToString());
}
else
{
MessageBox.Show("No. DVD in Unit");
}
The problem is that if I have a a CD in my CD-Drive and a DVD in my DVD-Driver, I am getting both's name and serial number. How can I make sure I only get the DVD?
Thank you so much for your help.

is it possible to create an object from a class in a VC++6 DLL from C# and call its member functions?
i know that i can call function from the Dll using Dllimport, but if these functions are member function in a clas ?
Thanks
MiNa

No, that's not possible. You have two options.
1. Make the VC++ DLL a COM DLL and use Interop to call it as a COM component.
2. Write a C++/CLI wrapper around the VC++ DLL and use the wrapper from C#. This would be the easier approach, IMO.
|
|
|
|
|
Do you have any links or articles that show the creation of C++ wrapper as i dont have any ideas about this stuff.
appreciate your help

Is there a way to find out what reference is keeping alive an object after garbage collection?
|
|
|
|
|
The answer is none, if GC occurs, then it's because there is no reference to an object being kept alive.

What if I issue GC.Collect()?
Can I get a list of the remaining objects?
|
|
|
|
|
No becuase even using GC.Collect() doesn't gaurantee collection, just implies that the GC should think about it.
|
|
|
|
|
That's incorrect, GC.Collect forces a collection immediately.
|
|
|
|
|
It won't give you the list of remaining objects, but it will force the GC to cycle through a collection. However, it is almost always a bad idea to call GC.Collect() yourself as it puts an undue burden on both your app and the GC.
Whenever the GC runs, it actually freezes the main thread of your application for the duration of the GC cycle. Making your own calls to GC.Collect() will end up causing more context switches and thread freezing/thawing than would otherwise occur and will actually end up hurting performance.

Since it returns void and accepts no parameters I knew that.
Scott Dorman wrote: Whenever the GC runs, it actually freezes the main thread of your application for the duration of the GC cycle
and I'm clear with that too.
But I use for testing purposes GC.Collect. The question is how can I realize a list
like some memory profilers do? Not as detaliated but just the actual situation of some objects (if they still exists).
I don't know how too explain more clearly. Anyway I'm playing with a memory profiler to see the allocations/gc's.
