Unalterable (Property)

In french: Inaltérable

Available only with these kinds of connection

The Property Unalterable allows to set the inalterability of a data file: the data file cannot be modified; only the additions will be possible.

You can:

Find out whether a data file is unalterable or not (data file defined in the data model editor or by programming).
Define the characteristics regarding the unalterability of a data file (when describing the data file by programming only).

Example

AFile is File Description
AnItem is Item Description

// Describe the "Customer" data file
UnFichier.Nom = "Client"
UnFile.Type = hFileNormal
Unalterable File = True

// Item description
OneSection.Name = "Message"
OneType = hItemText
OneSize = 40
HDescribeItem(AFile, AnItem)

// Validate the data file description
HDescribeFile(AFile)
