BUILT-IN MATHEMATICA SYMBOL
MessageDialog
MessageDialog[expr]
puts up a standard message dialog that displays expr together with an OK button.
MessageDialog[expr, {lbl1:>act1, lbl2:>act2, ...}]
includes buttons with labels 
that evaluate the corresponding 
if clicked.
- The contents expr can be text, graphics, or any other expression.
- MessageDialog returns immediately, but the dialog it generates remains up until one of its buttons is pressed, or the dialog window is closed.
- MessageDialog[expr] generates a dialog that includes an OK button. Pressing Enter or Esc is taken to be equivalent to pressing the OK button.
- MessageDialog places buttons automatically, outside the area used to display expr.
- MessageDialog by default puts up a notebook with a typical message dialog appearance. The option settings include WindowFloating->False, WindowSize->All, and WindowTitle->None.
- MessageDialog by default puts up a dialog in the middle of the main display screen. Explicit settings for WindowMargins override this.
- MessageDialog returns a NotebookObject corresponding to the notebook it creates.
- If Mathematica is run without a notebook front end, MessageDialog[expr, ...] prints expr in textual form, without any buttons or other controls.
