L’exemple suivant montre comment utiliser les membres SetDesktopLocation, Load et Activate.The following example demonstrates how to use the SetDesktopLocation, Load and Activate members. Pour exécuter l’exemple, collez le code suivant dans un formulaire appelé Form1 contenant un bouton appelé Button1 et deux contrôles Label appelés Label1 et Label2.To run the example, paste the following code in a form called Form1 containing a button called Button1 and two Label controls called Label1 and Label2.

static int x = 200;
static int y = 200;
void Button1_Click( System::Object^ sender, System::EventArgs^ e )

   // Create a new Form1 and set its Visible property to true.
   Form1^ form2 = gcnew Form1;
   form2->Visible = true;
   
   // Set the new form's desktop location so it  
   // appears below and to the right of the current form.
   form2->SetDesktopLocation( x, y );
   x += 30;
   y += 30;
   
   // Keep the current form active by calling the Activate
   // method.
   this->Activate();

}


// Updates the label text to reflect the current values of x 
// and y, which was were incremented in the Button1 control's 
// click event.
