YesNoAsynchronous (Function) In french: OuiNonAsynchrone Displays a message in a standard non-blocking dialog box with the answers "Yes" and "No" and calls a WLanguage procedure with the user's response.
Remarks: - This is a non-blocking dialog box. The WLanguage code that follows the call to YesNoAsynchronous continues to run. To close the window, the user must validate one of the buttons. When the user clicks one of the buttons, the code of a WLanguage procedure is run.
- In the WLanguage code following the call to the function, another modal window cannot be opened before closing the dialog box.
YesNoAsynchronous("Voulez-vous fermer cette fenêtre ?", MaProcédure_OKAnnuler)
INTERNAL PROCEDURE MaProcédure_OKAnnuler(nReponse int)
IF nReponse = Yes THEN
ToastDisplay("Vous voulez fermer la fenêtre !")
ELSE
ToastDisplay("Vous ne voulez pas fermer la fenêtre !")
END
END
