DeleteCmdDataSourceType

DeleteCmdDataSource behavior

Empty ("")

DeleteCmdDataSource is disregarded. Visual FoxPro uses the data source in the CursorAdapter DataSource property.

If the cursor associated with the CursorAdapter object is based on an ActiveX Data Object (ADO) RecordSet, Visual FoxPro uses the functionality of the ADO RecordSet to delete the record. To use this functionality, make sure the CursorAdapter DataSourceType property is set to "ADO".

"ADO"

DeleteCmdDataSource must be set to a valid ADO Command object. The ActiveConnection property of the ADO Command object must be set to a valid and open ADO Connection object.

Visual FoxPro sets the CommandText property of the ADO Command object to the value of the CursorAdapter DeleteCmd property. Visual FoxPro parses the command for parameters, creates parameter values if found, and sets them in the Command object.

The delete operation occurs as:

CursorAdapter.DeleteCmdDataSource.Execute()
