MyReg reg=new MyReg("AppName");  //Change AppName with your application name
reg["setting1"]=1;
reg[@"setting1\setting1"]="2";
reg[@"setting1\setting1\setting1"]="3";

MessageBox.Show(reg[@"setting1\setting1"].ToString());
MessageBox.Show(reg[@"setting1\setting1\setting1"].ToString());

Add your recent files in an ArrayList.

ArrayList list=new ArrayList();
list.Add(@"c:\file1.txt");
list.Add(@"c:\file2.txt");
reg.RecentFiles=list;
list.Clear();
list=reg.RecentFiles;
MessageBox.Show(list[1].ToString());

To open file *.abc with your application, use the code below:

reg.SaveOpenWith("abc", "myApplication", 
               @"c:\Project\Vc7\Km\Debug\Km.exe");
