CtAccess (Property)

In french: CxAccès

Available only with this kind of connection

The CtAccess property is used to set the type of access to the data file when connecting to a specific table via OLE DB. You can:

Get the type of access to the data file used to connect to a table via 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 through programming.
Define the type of access to the data file used for connecting to a table via OLE DB (when programmatically describing the data file only).
In this case, this property is equivalent to the CtDescribedAccess property.

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 through programming.

Example

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