JetGetSystemParameter() публичный статический Метод

Gets database configuration options.
JET_param.ErrorToString passes in the error number in the paramValue, which is why it is a ref parameter and not an out parameter.
public static JetGetSystemParameter ( JET_INSTANCE instance, JET_SESID sesid, JET_param paramid, int &paramValue, string &paramString, int maxParam ) : JET_wrn
instance JET_INSTANCE The instance to retrieve the options from.
sesid JET_SESID The session to use.
paramid JET_param The parameter to get.
paramValue int Returns the value of the parameter, if the value is an integer.
paramString string Returns the value of the parameter, if the value is a string.
maxParam int The maximum size of the parameter string.
Результат JET_wrn
