Write it to a persistent store in application_end, read it in application_start.

Its an interesting idea, but note that in my situation it is not a value type or a composite of value types, its an object that is doing something in its lifetime, and I want to keep it alive.

In that case, write it as a windows service ( the process that does this work )

Thanks for your note;
So it seems there is no way to do it without windows services? yes?
By the way it is not possible to create a windows service in a web application on the fly, isn't it ?

I doubt it. App end means what it says, your app is stopping.

Do you mean start one running, or create one ? You can control one. You could just run any old process, the point of a service is that you can control it from your app.

We have all seen it, you try to delete/move a file/folder and Windows presents you with a message stating that the item cannot be moved/deleted as it is in use by another program.
Is there a way to identify which processes have a "hold" on a file/folder within c#?
I assume that this will be through some API call, but at the moment I am at a loss to find any specific details
post.mode = postmodes.signature;
SELECT everything FROM everywhere WHERE something = something_else;

I have written a C++/CLI wrapper around some old C++ code so I can call it from C#, and a VERY simple demo app that calls the code. It works great. I've sent the release builds to the person I write this stuff for, and he gets an error when the code tries to call the C++ DLL :
Could not load file or assembly 'HDRLib, version xxxx culture neutral publickeytoken=null. This application has failed to start because the application configuration is incorrect.
The last bit is a verbatim quote of what HRESULT 0x800736B1 means, being the HRESULT it quotes. Again, this is managed C++ code being called from C#, works fine here.

I havejust begun to program, but only minor things. Mostly i read about sites for help but they just confuse me. Even the beginner C# tutorials here confuse me. This is mostly because of the words and the format. Some expect you to be already familiar with C++, and i am not. If someone could give me some advice of a site to go to, or any information that could possibly help me progress in the ways of C#. Ty for any help 
I never think of the future.It comes soon enough

You won't find a better site than this one. If you can't work out what we're talking about, buy a book and work through it, and keep asking questions.

Look at some of the free videos at learnvisualstudio.net as often watching a person and listening to what and why they are doing something is a great way to learn

Can anyone point me to a good example of the PrinciplePermission object (either in C# or VB .NET).
I am having trouble retreiving my own identity to use the Demand method. Whatever I enter, it refuses to grant me the permissions I request.
Also, I have managed to place an assembly into the GAC but for the life of me I cannot reference it. Any pointers would be most appreciated.

MSDN has a good example of the PrincipalPermission Class[^].
As to the GAC assemblies, you need to add a registry key entry to the following key:
HKLM\SOFTWARE\Microsoft\.NETFramework\AssemblyFolders

Favourites is just a list, probably stored as an XML file. Easy to do
Search is a waste of time, provide a link to google :P
Display is the big one, if you don't want to use IE as a control, then good luck.

Hi i have a little question. I tried to read a value from a registry like the following:
RegistryKey MyReg = Registry.CurrentUser.OpenSubKey("Software\\Microsoft\\Active Setup\\Installed Components\\{44BBA840-CC51-11CF-AAFA-00AA00B6015C}");
auth = MyReg.GetValue("Username").ToString();
It actually workt in a form, i get the username in that value. But when i try to implement this in my Windows Service, it is not able to read from the value?? I can create the MyReg object but can't get the value "Username" from it.. Does anybody has an idea why? And a solution for it? You would help me alot
Greetings

hm after some more debugging i found out that MyReg is null for some reason...
RegistryKey MyReg = Registry.CurrentUser.OpenSubKey("Software\\Microsoft\\Active Setup\\Installed Components\\{44BBA840-CC51-11CF-AAFA-00AA00B6015C}");
if (MyReg == null)
{
auth = "wrong";
}
else
{
auth = "right";
}
I get "wrong" as result. But when i do it in a C# form it works perfect.. Just not in the Windows Service ;(

I'm pretty certain that it has to do with the fact that you try to read a value from the HKEY_CURRENT_USER portion of the registry.
When you read the value from your Windows Forms applicaiton, the curent user is you. When the Windows service tries to read it, the current user is the local system account.
To get around this, open the Services control panel, right click on the appropriate service, choose the "Log On" tab, change the service's log on to your log on by choosing the "This Account" radio button and filling in the appropriate information.
I hope that helps.

Yes i know this is possible to run the service under a different account but won't i get the problem that, if i log in with an other user in my Windows, that i will get the same username?
