Characteristics of dialog box

  • The message is aligned to left.
  • The captions of buttons depend on runtime language of Windows (or on the runtime language of browser for a WEBDEV site).
  • 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 in a WINDEV application, question mark in a WEBDEV application) cannot be modified.
  • 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.

Line break in the dialog box

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

Miscellaneous

  • Timers (TimerSys) are not stopped when this function is called.
  • The text of the buttons is displayed in the system language.
