<Connection variable>.FileExist (Function)

In french: <Variable Connexion>.FichierExiste

Used to find out if a data file exists, i.e. if it has been physically created (<Source>.Creation or <Source>.CreateIfNotFound).

Note: Substitutions currently being made to the data file (using functions HSubstDir, <Source>.ChangeDir and <Source>.ChangeName) are taken into account.

// Description de la connexion
MaConnexion is Connection

// Test de l'existence d'un fichier de données Client/Serveur
IF MaConnexion.FileExist("MonFichier.FIC") = True THEN
	// Traitements
	...
END
