Unless I misunderstand the error is correct:

The Key <big>ConnectionString</big> does not exist in the app setting configuration section

as in

<add key="<big>Main.ConnectionString</big>" value="...

the key is "Main.ConnectionString"

Hope this give you the answer you need!

Is there an app.config or yourapplicationname.exe.config in the installation folder?

There is the problem. Say your application builds to an exe called Foo.exe, it expects the app config file to be named Foo.exe.config, not app.config. So you can't just copy the app.config into the installer directly.

Make sure the Installer project has "Primary output from your project name here (Active)" in it. As long as the app.config exists in the source project it should be installed with the correct name.

Also Greg Chelstowski's post is correct, you should consider using a ConnectionString element in your app.config rather than adding the connection string as an app setting.

Why do you not use ConfigurationManager.AppSettings["ConnectionString"].Value.ToString() instead?

Moreover, why do you store your connection string as an appsetting, and not as connectionString in your app.config?

var question = (_2b || !(_2b));

System.Net.IPAddress[] myIpAddresses = System.Net.Dns.GetHostAddresses(Environment.MachineName);

<Edit> oops, only just saw you wanted remote machine. In that case just specify the HostName instead of Environment.MachineName like so...

System.Net.IPAddress[] myIpAddresses = System.Net.Dns.GetHostAddresses("SomeComputer");

</Edit>

<Edit2> OMG, i think I'm experiencing dyslexia!!

If you want to run the app remotely and get its machines IP use the 1st snippet, but like CG said it needs to be sent somewhere...

If you have the remote machines HostName you can use the 2nd snippet on the local machine.

Have application.exe get the IP address, and write it into a SQL database. That would be the easiest way to do it...

Yes, if you write an app that runs on that remote machine, it can read and broadcast the IP address if you like. Of course, it needs somewhere to send it.

Format your grid to show those columns. This is basic stuff. You should buy a winforms book and read it, or try reading MSDN.
