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.
WINDEV To customize this dialog box (as well as all the system dialog boxes of your application), check "Apply the skin template theme to the system windows (Info, YesNo, Confirm, Dialog)" in the "Style" tab of project description. See Customizing dialog boxes for more details.

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?")
