private:
   void InitializeMyButton()
   {
      // Create and initialize a Button.
      Button^ button1 = gcnew Button;
      
      // Set the button to return a value of OK when clicked.
      button1->DialogResult = ::DialogResult::OK;
      
      // Add the button to the form.
      Controls->Add( button1 );
   }

private void InitializeMyButton()
 {
    // Create and initialize a Button.
    Button button1 = new Button();
 
    // Set the button to return a value of OK when clicked.
    button1.DialogResult = DialogResult.OK;
 
    // Add the button to the form.
    Controls.Add(button1);
 }

Private Sub InitializeMyButton()
    ' Create and initialize a Button.
    Dim button1 As New Button()
    
    ' Set the button to return a value of OK when clicked.
    button1.DialogResult = DialogResult.OK
    
    ' Add the button to the form.
    Controls.Add(button1)
End Sub

Remarks

If the DialogResult for this property is set to anything other than None, and if the parent form was displayed through the ShowDialog method, clicking the button closes the parent form without your having to hook up any events. The form's DialogResult property is then set to the DialogResult of the button when the button is clicked.

For example, to create a "Yes/No/Cancel" dialog box, simply add three buttons and set their DialogResult properties to Yes, No, and Cancel.
