CtAccess (Property)

In french: CxAccès

Available only with this kind of connection

The Property CxAccess allows you to manage the type of file access when connecting OLE DB to a specific table. You can:

Find out the type of access to the data file used for connecting to a table by OLE DB.
The type of access can correspond to:
- the type of access defined in the data model editor,
- the type of access specified in HConnect, HDescribeConnection or HOpenConnection.
  This property can be used for a data file or for a connection defined in the data model editor or by programming.
Define the type of access to the data file used for connecting to a table by OLE DB (when the data file is described by programming).
In this case, this property is equivalent to CtDescribedAccess.

Reminder: HConnect is used to redefine one or more parameters of the OLE DB connection to a table. By default, the characteristics of the OLE DB connection are defined:

in the data model editor during the description of the data file,
when the data file was described by programming.

Example

// Find out the type of access to the Customer data file
ResAccessType = Customer.CtAccess
