When you created the new Form1(), you created a whole new instantiation of that form in memory, so you changed HIS label and not the one that is visible. You could tackle that a couple of ways. You could put in the Class1's constructor an argument for a label like this Class1(label FormsLabelIWantToChange) { FormsLabelIWantToChange = "test"; } Another way to do it (I think) would be to make Form1's label member s public static, then as you are in the same namespace you could do something like this in your class: Form1.label1.text = "test"; There are only 10 types of people in this world....those that understand binary, and those that do not.

Sounds like your trying to apply Perl design to a C# program. Before you go too far, you should first try to understand the database access classes in the System.Data namespace. A DataTable acts a lot like an array of DataRows, where individual fields can be accessed by name. But if you really want something like a perl array of hashes, it might look like this: using System.Collections; ... ArrayList a = new ArrayList(); Hashtable h = new Hashtable(); h.Add( "One", 1 ); h.Add( "Two", 2 ); a.Add( h ); // Later h = (Hashtable)a[0]; Console.WriteLine( h["One"] ); Burt Harris
