Examples

In this example, you change the form's start position to the center of the screen and display the position information using a label. This example assumes that you have already created a Form named Form1.

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

Remarks

This enumeration is used by the StartPosition property of the Form class. It represents the different start positions of the form. The default start position is WindowsDefaultLocation.
