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 button caption depends 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 in yellow triangle) cannot be modified.
WINDEV To customize this dialog box (as well as all system dialog boxes of your application), check "Apply the theme of skin template to the system information windows" 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:
Warning("The XXX form was modified" + CR + ...
"Any new modification must be validated.")
is equivalent to:
Warning("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:
Warning(
[
This operation was not validated.

Contact the application provider
])
