Delphi has at lest 3 ways of displaying a message box
Showmessage('your text'); is the simplist,
Messagedlg('Your text',Message type, [The buttons you want],the help context); The most useful?
and
messagebox('your text','the caption',flags);
This last one is most like a VB (Windows generic message box).
The help files will give you details on the parameters required for each of these.
