HErrorDuplicates (Function)

In french: HErreurDoublon

Not available with this kind of connection

Used to check whether a duplicate error occurred.

This function can be used when the automatic management of errors is disabled by HOnError. By default, WINDEV includes an automatic management of duplicates.

Example

See additional examples

// Gestion d'une erreur de doublons
IF HModify(Client) = False THEN
	IF HErrorDuplicates() = True THEN 
		sNomRub is string
		sNomRub = HErrorInfo(hErrItem)
		Error("Doublon: cet enregistrement ne peut être modifié", "Rubrique associée à l'erreur: " + sNomRub, ...
				"Valeur de la rubrique: " + {"Client." + sNomRub})
	END
END

Syntax

<Result> = HErrorDuplicates()

<Result>: Boolean

True if a duplicate error occurs,
False otherwise (no error).

Remarks

The management of duplicates is enabled by default. To enable or disable the management of duplicates, use HSetDuplicates.
This function replaces HDuplicates, which is kept for compatibility with WINDEV 5.5.
