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?")
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?
])

NO BROWSER FUNCTION AVAILABLE
Your documentation should go to trash, it is not possible to use YesNo in Browser, add a damn example, you only provide a skeletoon of the function but there are tons of users unable to use it. I never expect something from PCSOFT and I still get disapointed
