| Array of Runtime Labels Code: namespace sud

| Add labelTest2[0] = new Label(); before you call its properties. You've created an array of 10 Labels, not 10 Labels. |

| I still got the same error but I did manage to get it to work from that suggestion. Changes in blue: Code: namespace sud
{
public partial class sud : Form
{
private Label[] labelTest2;
public sud()
{
InitializeComponent();
labelTest2 = new Label[10];
}
private void sud_Load(object sender, EventArgs e)
{
this.labelTest2[0] = new Label();
this.labelTest2[0].Size = new System.Drawing.Size(50, 50);
this.labelTest2[0].Location = new System.Drawing.Point(40, 40);
this.labelTest2[0].Name = "cellTest";
this.labelTest2[0].Text = "Test";
this.Controls.Add(labelTest2[0]);
}
} // end partial class: sud
} // end namespace: sud

| Yup. You had 10 references to a label. It's analgous to in C++ creating 10 pointers to something and trying to access an element of it. It's not going to fly unless you allocate memory to it. |
