Question

HI! I try to run diferent examples but get errors with some of the references. Like a yellow tag in the references on some of 'em like the System.Configuration I guess there some dll's missing but where can i find 'em`? using System.net I try to do something like getting an IPAddress. There is nothing called system.net in add references. I'm new to C# so please help? Yepp

Answer 1

OK... with a little more research I found my answer -------------------------------- using Microsoft.Win32; string myPath = ""; RegistryKey rk = Registry.LocalMachine.OpenSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\App Paths\\SomeProg.exe", false); if(rk != null) { myPath = rk.GetValue("").ToString(); } ------------------------------------ In the code above I am getting the "Default" value which contains the programs executable path. The "false" parameter says that I want to open the key as read-only. I am not sure if the rk != null check is the right way to check that the key existed, but at first test this appears to work.
