CreationName | Инфраструктура. Gets the name that is used by the runtime engine to create an instance of the EventHandlerClass. This property is read-only. |
|
DebugMode | Инфраструктура. Gets or sets a Boolean that indicates whether a task should check if breakpoints are enabled. |
|
DelayValidation | Инфраструктура. Gets or sets a Boolean that indicates whether validation of the task is delayed until run time. The default value is false. |
|
Description | Инфраструктура. Gets or sets the description of the EventHandlerClass object. |
|
Disable | Инфраструктура. Gets a Boolean that indicates whether the EventHandlerClass object is disabled. |
|
Executables | Инфраструктура. Gets a collection of executable objects in this container which run when the event occurs. This property is read-only. |
|
ExecutionDuration | Инфраструктура. Gets a value that indicates the amount of time that the container spent in execution, in milliseconds. This property is read-only. |
|
ExecutionResult | Инфраструктура. Gets a value that indicates the success or failure of the execution of the EventHandlerClass object. |
|
ExecutionStatus | Инфраструктура. Gets a value that indicates the current status of the execution of the EventHandlerClass object at the time of the call. |
|
FailPackageOnFailure | Инфраструктура. Gets or sets a Boolean that indicates whether the package fails when a child container fails. This property is used on containers, not the package itself. |
|
FailParentOnFailure | Инфраструктура. Gets or sets a Boolean that indicates whether the parent container fails when a child container fails. |
|
ForcedExecutionValue | Инфраструктура. If the ForceExecutionValue property is set to true, gets or sets a value that specifies the optional execution value the package returns. |
|
ForceExecutionResult | Инфраструктура. Gets or sets a DTSForcedExecResult enumeration value that specifies the forced execution result of the container. |
|
ForceExecutionValue | Инфраструктура. Gets or sets a Boolean that indicates whether the execution value of the container should be forced to contain a particular value. |
|
ID | Инфраструктура. Gets the ID, which is a GUID, of the EventHandlerClass. 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. Gets 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 EventHandlerClass object. |
|
LocaleID | Инфраструктура. Gets or sets an Integer that indicates the Microsoft Win32® localeID to use when the EventHandlerClass object is executed. |
|
LogEntryInfos | Инфраструктура. Gets a collection of log entry definitions. This property is read-only. |
|
LoggingMode | Инфраструктура. Gets or sets a value from the DTSLoggingMode enumeration that indicates the logging mode of the container. |
|
LoggingOptions | Инфраструктура. Gets an object that contains properties that indicates the filtering and logging resource for containers. This property is read-only. |
|
MaximumErrorCount | Инфраструктура. Gets or sets an Integer value that specifies the maximum number of errors that can occur before the EventHandlerClass object stops running. |
|
Name | Инфраструктура. Gets or sets the name of the EventHandlerClass. |
|
Parent | Инфраструктура. Gets the parent container. The value is read-only. |
|
PrecedenceConstraints | Инфраструктура. Gets a collection of precedence constraints, if any, found on the executable objects in this container. This property is read-only. |
|
Properties | Инфраструктура. Gets a collection of IDTSProperty100 objects. This property is read-only. |
|
StartTime | Инфраструктура. Gets the time when the container starts execution. This property is read-only. |
|
StopTime | Инфраструктура. Gets the time when the container stops execution. This property is read-only. |
|
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. |
|
TransactionOption | Инфраструктура. Gets or sets a value that indicates whether the container participates in transactions. |
|
VariableDispenser | Инфраструктура. Gets a variable dispenser object so that variables associated with the container can be locked for reading or writing. |
|
Variables | Инфраструктура. Gets a collection object that contains the variables associated with this container. This property is read-only. |

Методы
| Имя | Описание | |
|---|---|---|
|
AcceptBreakpointManager | Инфраструктура. Passes a IDTSBreakpointManager100 to a task. The task will use the breakpoint manager to create, remove, and check the status of breakpoints. This method is called by the runtime and is not used in code. |
|
ComputeExpressions | Инфраструктура. Computes the expressions of this EventHandlerClass object. |
|
Equals | (Производный от Object.) |
|
Execute | Инфраструктура. Runs the application, container, or package as part of a package workflow. |
.gif "Защищенный метод") |
Finalize | (Производный от Object.) |
|
GetExpression | Инфраструктура. Returns the expression for the specified property or nullпустая ссылка (Nothing в Visual Basic) if no expression is assigned. |
|
GetHashCode | (Производный от Object.) |
|
GetParentID | Инфраструктура. Gets the parent identifier of this container. |
|
GetType | (Производный от Object.) |
|
IDTSSuspend100_ResumeExecution | Инфраструктура. Resumes execution of the task after pausing. The task or container is resumed by the runtime engine. |
|
IDTSSuspend100_SuspendExecution | Инфраструктура. Notifies that the executable needs to suspend. This method is called by the runtime engine. |
|
LoadFromXML | Инфраструктура. Loads an EventHandlerClass from the specified XML document. |
|
MemberwiseClone | (Производный от Object.) |
|
RegenerateID | Инфраструктура. Creates a new GUID for the container and updates the container ID property. |
|
ResumeExecution | Инфраструктура. Resumes execution of the task after pausing. The task or container is resumed by the runtime engine. |
|
SaveToXML | Инфраструктура. Saves an EventHandlerClass to the specified XML document. |
|
SetExpression | Инфраструктура. Assigns the specified expression to the property. Specify nullпустая ссылка (Nothing в Visual Basic) to remove an existing expression from the property. |
|
SuspendExecution | Инфраструктура. Notifies that the executable needs to suspend. This method is called by the runtime engine. |
|
ToString | (Производный от Object.) |
|
Validate | Инфраструктура. Allows the container to determine if it contains invalid settings that will prevent it from executing successfully. |
