Ejemplos

En el ejemplo de código siguiente se muestra cómo crear dos formularios: Form1 y Form2.The following code example shows how to create two forms: Form1 and Form2. Establezca la propiedad IsMdiContainer de Form1 en true y conviértalo en MdiParent de Form2.Set the IsMdiContainer property of Form1 to true and make it the MdiParent of Form2. A continuación, cree un botón, button1, en cada formulario.Next, create a button, button1, on each form. Cuando se hace clic en el botón del formulario primario, el controlador de eventos muestra el formulario secundario.When the button on the parent form is clicked, the event handler displays the child form. Cuando se hace clic en el botón del formulario secundario, el controlador de eventos muestra la propiedad Name de su formulario primario.When the button on the child form is clicked, the event handler displays the Name property of its parent form. Use los dos segmentos de código siguientes para sobrescribir los controladores de eventos de button1 en ambos formatos.Use the following two code segments to overwrite button1 event handlers in both forms.

   // The event handler on Form1.
private:
   void button1_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ )
   {
      // Create an instance of Form2.
      Form1^ f2 = gcnew Form2;

      // Make this form the parent of f2.
      f2->MdiParent = this;

      // Display the form.
      f2->Show();
   }
// The event handler on Form1.
private void button1_Click(object sender, System.EventArgs e)
{
    // Create an instance of Form2.
    Form2 f2 = new Form2();
    // Make this form the parent of f2.
    f2.MdiParent = this;
    // Display the form.
    f2.Show();
}
' The event handler on Form1.
Private Sub button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
    ' Create an instance of Form2.
    Dim f2 As New Form2()
    ' Make this form the parent of f2.
    f2.MdiParent = Me
    ' Display the form.
    f2.Show()
End Sub
   // The event handler on Form2.
private:
   void button1_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ )
   {
      // Get the Name property of the Parent.
      String^ s = ParentForm->Name;

      // Display the name in a message box.
      MessageBox::Show( String::Concat( "My Parent is ", s, "." ) );
   }
// The event handler on Form2.
private void button1_Click(object sender, System.EventArgs e)
{
    // Get the Name property of the Parent.
    string s = ParentForm.Name;
    // Display the name in a message box.
    MessageBox.Show("My Parent is " + s + ".");
}
' The event handler on Form2.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    ' Get the Name property of the parent.
    Dim s As String = ParentForm.Name
    ' Display the name in a message box.
    MessageBox.Show("My parent is " + s + ".")
End Sub
