Characteristics of dialog box

  • The title of the dialog box corresponds to the title of the current window (or page).
  • To modify or define the title of dialog box, use NextTitle.
  • The message is aligned to left.
  • The captions of buttons depend on the runtime language of Windows.
  • The maximum number of characters cannot exceed 4096. If a larger string is passed in parameter, it will be truncated.
  • The icon displayed (exclamation mark) cannot be modified.

Line break in the dialog box

The CR string (Carriage Return) can be used to force a break to the next line. For example:
YesNo("The XXX form was modified." + CR + ...
"Do you want to save it before exiting?")
is equivalent to:
YesNo("The XXX form was modified.", ...
"Do you want to save it before exiting?")
