TObjectStates values indicate the current state of an ADO object.
TObjectStates = set of TObjectState;
TObjectState TObjectStates;
Use TObjectStates values to determine the current activity status of a connection or recordset.
The constants that make up the TObjectStates type correspond directly to the similarly named constants used for the State property of the ADO Connection, Command, and Recordset objects. For additional information on these ADO constants and their effects, see the Microsoft Data Access SDK help in the topic for the State property.
TObjectStates consists of the five constants summarized in the following table:
|
