Do you mean using a 2 dimention array of PictureBox controls?

And you mean, when coding in C#, from the beginning, you have to plane every object and other things and there is no way to decide what to do at runtime, like scripting languages?

PictureBox[,] pictureBoxes;

        private void Form1_Load(object sender, EventArgs e)

                for (int y = 0; y < 20; y++)
                {
                    pictureBoxes[x, y] = new PictureBox();
                    pictureBoxes[x, y].Name = "pictureBoxX" + x.ToString() + "Y" + y.ToString();

                    pictureBoxes[x, y].Height = 10;
                    pictureBoxes[x, y].Left = x * 10;
                    pictureBoxes[x, y].Top = y * 10;
                    pictureBoxes[x, y].BorderStyle = BorderStyle.FixedSingle;
                    pictureBoxes[x, y].Click += new EventHandler(PictureBox_Click);

                }

Name: FormPosition
Type: System.Drawing.Point
Scope: User (Take care of this, it made me crazy to get this point: Application scope, is read-only and it will be the same as the value you gave to it at the beginning and you can not change it at runtime! But User scope is made to be assigned both at the beginning and at runtime. )
Value: 100, 100

<br />
Point formPosition = global::YourNamespace.Properties.Settings.Default.FormPosition;//YourNamespace = (The main namespace of your application)<br />

<br />
Point formPosition = new Point(MyForm.Left, MyForm.Top);<br />
global::YourNamespace.Properties.Settings.Default.FormPosition = formPosition;//YourNamespace = (The main namespace of your application)<br />
