|
ID | Инфраструктура. Gets the GUID of the ForEachLoopClass. The value is read-only. |
|
IDTSSuspend100_SuspendRequired | Инфраструктура. Gets or sets a Boolean that indicates if tasks should suspend when they encounter a breakpoint. This value is set by the runtime engine for tasks and containers when a breakpoint is encountered. |
|
IsDefaultLocaleID | Инфраструктура. A Boolean that indicates whether the container uses the default locale. This property is read-only. |
|
IsolationLevel | Инфраструктура. Gets or sets the isolation level of the transaction in the ForEachLoopClass object. |
|
LocaleID | Инфраструктура. Gets or sets an Integer that indicates the Microsoft Win32® localeID to use when the ForEachLoopClass object is executed. |
