public:
   void InitMyForm()
   {
      // Adds a label to the form.
      Label^ label1 = gcnew Label;
      label1->Location = System::Drawing::Point( 54, 128 );
      label1->Name = "label1";
      label1->Size = System::Drawing::Size( 220, 80 );
      label1->Text = "Start position information";
      this->Controls->Add( label1 );
      
      // Moves the start position to the center of the screen.
      StartPosition = FormStartPosition::CenterScreen;
      
      // Displays the position information.
      label1->Text = String::Format( "The start position is {0}", StartPosition );
   }
public void InitMyForm()
{
    // Adds a label to the form.
    Label label1 = new Label();
    label1.Location = new System.Drawing.Point(54, 128);
    label1.Name = "label1";
    label1.Size = new System.Drawing.Size(220, 80);
    label1.Text = "Start position information";
    this.Controls.Add(label1);

    // Moves the start position to the center of the screen.
    StartPosition = FormStartPosition.CenterScreen;
    // Displays the position information.
    label1.Text = "The start position is " + StartPosition;	
}
Public Sub InitMyForm()
   ' Adds a label to the form.
   Dim label1 As New Label()
   label1.Location = New System.Drawing.Point(54, 128)
   label1.Name = "label1"
   label1.Size = New System.Drawing.Size(220, 80)
   label1.Text = "Start position information"
   Me.Controls.Add(label1)
   
   ' Moves the start position to the center of the screen.
   StartPosition = FormStartPosition.CenterScreen
   ' Displays the position information.
   label1.Text = "The start position is " + StartPosition
End Sub
