Remarks
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 the 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 as 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?")
You also have the ability to use the syntax of multiline strings. For example:
YesNo(
[
The XXX form has been modified.
Do you want to save changes before closing?
])
