Features of the 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 button caption depends on the runtime language of Windows.
  • The maximum number of characters cannot exceed 4096. If a larger string is passed as parameter, it will be truncated.
  • The icon displayed (exclamation mark in yellow triangle) 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:
Warning("The XXX form was modified" + CR + ...
"Any new modification must be validated.")
is equivalent to:
Warning("The XXX form was modified", ...
"Any new modification must be validated.")
You also have the ability to use the syntax of multiline strings. For example:
Warning(
[
This operation was NOT validated.
 
Contact the application provider
])
