The simplest dialog window is the message box. Most message boxes present simple messages and offer the user one, two, or three responses (represented by buttons). A message box is easy to use and is appropriate when an application requires a clearly defined response to a static message. However, standard message boxes lack flexibility in size and placement on the screen and are limited in the choices they offer the user. Applications that require more control over the size, position, and content should use enhanced message boxes or regular Dialog Windows instead of standard message boxes.
