Stored procedures
Used to check whether a duplicate error occurred.
WINDEV 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
// Manage a duplicate error
IF HModify(Customer) = False THEN
IF HErrorDuplicates() = True THEN
sItemName is string
sItemName = HErrorInfo(hErrItem)
Error("Duplicate: this record cannot be modified", ...
"Item associated with the error: " + sItemName, ...
"Value of the item: " + {"Customer. " + sItemName})
END
END
Syntax
<Result> = HErrorDuplicates()
<Result>: Boolean
  • True if a duplicate error occurred,
  • 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.
