Can I add the exeConfiguration file to a project in VS, so I can see the changes made with the configSection interface?

My listbox displays an empty string when I add an form to it. I tried to override ToString and set listbox.DisplayMember to a property. It works when i use lbxHeader1.Items[1].ToString(); Does anybody have a clue what could be wrong? This is my definitions: public partial class TextDisplay : Form { public override string ToString() {...} } partial class Form1 { this.lbxHeader1 = new System.Windows.Forms.ListBox(); } public partial class Form1 : Form { private void lbxHeader1_MouseDoubleClick(object sender, MouseEventArgs e) { TextDisplay TextDispDialog = new TextDisplay(); lbxHeader1.Items.Add(TextDispDialog); } }

How do I modify the data in my datatable, when it allready contains a row with the primary key? I don't know how to find the index? in C#.
