How is ignoring encapsulation sounding good? 
It's an OO world.

Hi!
I've developed an application using Windows Forms Managed C++. I've deployed it and installed at client systems. At present I can run many instances of my application at the same time. But I want only one at any particular instancde(ie. if I click the desktop short cut for my app,when already an instance is running, another instance of my app should not run). How to do this?

Have you searched[^] at all, you got the keywords right?
BTW: a second instance will run shortly, discover it isn't the first, possibly pass on the command line, then exit.

Technically speaking, you cannot prevent a second instance from coming up, but you can code your app in such a way that it detects if an instance is already running and pass on the command-line arguments and then exit. There are many approaches to this, one is to use a Mutex and the other is to use the System.Diagnostics.Process class to check if the process is already running.

I've a C# application, sort of monitoring application which must run as Admin. So I added manifest file in that. I tried many ways to do, added in registry, added shortcut in Startup directory, added in Task Scheduler. But nothing seems to be working. Any idea ?

And you have tried running the application logged on as Admin?
Any UI components?
Have you tried wrapping it as a service and installing as service?

You cannot do this.
Every user is not going to have admin permissions ability. That means you cannot run the app as a normal user at all. Th eonly people who could run the app are those who are members of the Administrators group.
You have no choice but to run this as a service under a dedicated admin account.
What are you doing that requires admin priv's anyway?

-Update network IPs
-Take screenshot
-Socket Connection
-Shutdown/Restart PC
I don't know if any of above requires admin privilege but app doesnt work properly without it.

What does this mean exactly? Are you changing the IP of the workstation?? Why would you do this outside of changing the network the machine is on? This is never done on an application basis.
The rest does not take an admin to do. The exception may be Shutdown/Restart because of policy settings.

If you can't run it logged on as Admin, then it doesn't matter what you do, it aint going to run. So first, get it running then you should be able to run on startup.
If it has no UI, it probably should not have been posted here in the Windows Forms forum.
Like I said get it working first and then seperate the components so the admin stuff runs as a service and the "all user" stuff like screen grabs, runs as a startup app. Then you just need to find a way of communicating with the service.
Hope that helps

Its not console application, not service and it has UI but when on specific keys are pressed.

why would I separate if I can run admin stuff  and to grab screen no need to run on startup, just run it when need to grab.
using service is just last option

You said it had no UI and now you say it does!
As mentioned to you before, a user can not run code that requires Administrator rights unless they have Administrator rights. That's why you need to separate that code and run it as a service. A service can run with Administrator rights regardless of the users rights.
All the best.

it has no UI until user press some combination of keys, which is quite rare.

This isn't a web app. There's no replacement for "~" outside of a web app.
It's always best to use fully qualified filepaths, even if you have to build them from a known folder, like this:
string DesktopFolder = Environment.GetFolderPath(SpecialFolder.Desktop);
.
.
.
string imagePath = Path.Combine(DesktopFolder, "folobiz\\school\\Images\default.jpg");

Thank you for your kind replay

As Dave replied, that particular notation is reserved for web-apps. You can write a short method that replaces the "~" character with the path of the running executable, similar to this;
public static string ToRelativePath(string source)
{
return source.Replace("~",
System.IO.Path.GetDirectoryName(
System.Reflection.Assembly.GetEntryAssembly().Location));
}
