NextTitle("Modification de fiche")
Res = Confirm("Des modifications ont été apportées à la fiche.", ...

Features of the dialog box

The message is aligned to the left.
The text of the buttons changes according to the language used by Windows at runtime (or used by the browser, in the case of a WEBDEV website).
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 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.

To customize this dialog box (and all the system dialog boxes in your application), check "Customize system windows (Info, YesNo, Confirm, Dialog)" in the "Style" tab of the project description. For more details, see Customizing dialog boxes.

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("La fiche XXX a été modifiée." + CR + ...
	"Voulez-vous la sauver avant de quitter ?")

is equivalent to:

Confirm("La fiche XXX a été modifiée.", ...
	"Voulez-vous la sauver avant de quitter ?")

You also have the ability to use the syntax of multiline strings. For example:

Confirm(
[
La fiche XXX a été modifiée.

Voulez-vous la sauver avant de quitter ?
])

Windows events are not stopped when this function is called.
DelayBeforeClosing limits how long the message is displayed. The dialog box is automatically closed. For question or confirmation dialog boxes, the default button corresponds to the expected answer.
The text of the buttons is displayed in the system language.
