Waw. Who would come up with "free forms"!
I had pasted the OP's code into an existing VB.NET project, and wasn't surprised it didn't compile at all, so I did not understand what the OP was on about...

Also works on older versions of VB.NET. There's a thread on StackOverflow[^] on the subject

I spent about 30 minutes looking for some global variable today with no luck... Encapsulation is one of the most important aspects of Object Oriented Programming and Microsoft decides to NOT use it for Forms. I ask you, what is more crippling to the programmer's mind? 
This sort of stuff leads to very unexpected behaviour in software... Microsoft should have dropped it in VB4 
It's an OO world.

After having read the reasoning on that thread, I can see why. Can't say I like it, just that I can see the reasoning. Just for fun, how about assigning null to a valuetype?

Yes, I'm glad too that Microsoft introduced C#

In what way is encapsulation broken? The only problem I can see with this is that if you wanted your constructor to be private then this would ruin it for you. Other than that, normal class access rules still apply.
VB.NET just acts like you declared Dim Form1 As New Form1. So the first call to a non-shared member of Form1 causes a new instance of Form1 to be created. But then, you wouldn't normally be calling non-shared members on the class anyway, so all in all the problem is fairly limited (that is to say: if you wrote your code without knowing this quirk, you wouldn't ever find out about it, because you wouldn't be directly accessing members through Form1 but via an instance).
That is not to say that I at all agree with this. I hated this quirk in VB6 already, as it was more confusing than anything. Completely unintuitive and destructive to the idea of classes and OOP for new programmers if they see this behaviour

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

-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
