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?")
