Return Value

Type: System.Windows.Forms::DialogResult
One of the DialogResult values.

You can use the owner parameter to specify a particular object, which implements the IWin32Window interface, that will serve as the dialog box's top-level window and owner. A message box is a modal dialog box, which means no input (keyboard or mouse click) can occur except to objects on the modal form. The program must hide or close a modal form (typically in response to some user action) before input to another form can occur.

By default, the message box displays an OK button.
