Proprietà

	Nome	Descrizione
	AssignExpression	Infrastruttura. Gets or sets an expression to increment or decrement the loop counter.
	CreationName	Infrastruttura. Returns the name that is used by the runtime to create an instance of the object and add it to its collection, if there is a collection for the object. This property is read-only.
	DebugMode	Infrastruttura. Gets or sets a Boolean that indicates whether a task should check if breakpoints are enabled.
	DelayValidation	Infrastruttura. Gets or sets a value that indicates whether validation of the task is delayed until run time.
	Description	Infrastruttura. Gets or sets a description about the object.
	Disable	Infrastruttura. Gets or sets a value that indicates whether the IDTSContainer100 object is disabled.
	DisableEventHandlers	Infrastruttura. Gets or sets a Boolean that indicates whether the event handlers on task are disabled.
	EvalExpression	Infrastruttura. Gets or sets the expression that is evaluated on each pass of the loop.
	EventHandlers	Infrastruttura. Returns a collection of event handler objects. This field is read-only.
	EventInfos	Infrastruttura. Returns a collection of IDTSEventInfo100 objects. This field is read-only.
	Executables	Infrastruttura. Returns a collection of executable objects that are processed during the ForLoopClass iteration.
	ExecutionDuration	Infrastruttura. Returns a value that indicates the amount of time that the container spent in execution, in milliseconds. This property is read-only.
	ExecutionResult	Infrastruttura. Gets a value that indicates the success or failure of the execution of the IDTSContainer100 object.
	ExecutionStatus	Infrastruttura. Gets the current status of the execution of the IDTSContainer100 object at the time of the call.
	FailPackageOnFailure	Infrastruttura. Gets or sets a value that indicates whether the package fails when a child container fails.
	FailParentOnFailure	Infrastruttura. Gets or sets a value that indicates whether the parent container fails when a child container fails.
	ForcedExecutionValue	Infrastruttura. When ForceExecutionValue is true, gets or sets a value that specifies the optional execution value that the package returns.
	ForceExecutionResult	Infrastruttura. Gets or sets the forced execution result of the container.
	ForceExecutionValue	Infrastruttura. Gets or sets a value that indicates whether the execution value of the container should be forced to contain a particular value.
	ID	Infrastruttura. Returns a unique ID assigned to the object. This is usually a GUID. This property is read-only.
	IDTSSuspend100_SuspendRequired	Infrastruttura. Gets or sets a Boolean that indicates whether 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.
	InitExpression	Infrastruttura. Gets or sets an optional initialization expression.
	IsDefaultLocaleID	Infrastruttura. Gets a value that indicates whether the container uses the default locale.
	IsolationLevel	Infrastruttura. Gets or sets the isolation level of the transaction in the IDTSContainer100 object.
	LocaleID	Infrastruttura. Gets or sets the identifier of the locale to use when the IDTSContainer100 object is executed.
	LogEntryInfos	Infrastruttura. Gets a collection of information about a log entry.
	LoggingMode	Infrastruttura. Gets or sets the logging mode of the container.
	LoggingOptions	Infrastruttura. Gets an object that contains properties that indicates the filtering and logging resource for containers.
	MaximumErrorCount	Infrastruttura. Gets or sets the maximum number of errors that can occur before the container stops running.
	Name	Infrastruttura. Gets or sets a name assigned to the object.
	Parent	Infrastruttura. Gets the parent of the container.
	PrecedenceConstraints	Infrastruttura. Returns a IDTSPrecedenceConstraints100 collection. This field is read-only.
	Properties	Infrastruttura. Returns a set of properties for the ForLoopClass into a IDTSProperties100 collection.
	StartTime	Infrastruttura. Returns the time that the container began execution. This property is read-only.
	StopTime	Infrastruttura. Returns the time that the container ended execution. This property is read-only.
	SuspendRequired	Infrastruttura. Gets or sets a Boolean that indicates whether 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	Infrastruttura. Gets or sets a DTSTransactionOption enumeration value that indicates whether the container participates in transactions.
	VariableDispenser	Infrastruttura. Gets an IDTSVariableDispenser100 object so variables associated with the container can be locked.
	Variables	Infrastruttura. Gets a collection that contains the variables associated with this container.

Metodi

	Nome	Descrizione
	AcceptBreakpointManager	Infrastruttura. 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	Infrastruttura. Computes the expressions of the ForLoopClass object.
	Equals	Ereditato da Object.
	Execute	Infrastruttura. Executes the executable.
	Finalize	Ereditato da Object.
	GetExpression	Infrastruttura. Returns a String that contains the expression for the specified property. Null means no expression is assigned.
	GetHashCode	Ereditato da Object.
	GetParentID	Infrastruttura. Gets the parent identifier of this container.
	GetType	Ereditato da Object.
	IDTSForLoop100_Execute	Infrastruttura. Executes the executable.
	IDTSForLoop100_Validate	Infrastruttura. Verify that the executable will successfully execute by validating all its dependencies and other items before executing it.
	IDTSSuspend100_ResumeExecution	Infrastruttura. Resumes execution of the task after pausing. The task or container is resumed by the runtime engine.
	IDTSSuspend100_SuspendExecution	Infrastruttura. Indicates that the executable needs to suspend. This method is called by the runtime engine.
	LoadFromXML	Infrastruttura. Loads data stored in XML format.
	MemberwiseClone	Ereditato da Object.
	RegenerateID	Infrastruttura. Creates a new identifier for the container and updates the container identifier.
	ResumeExecution	Infrastruttura. Resumes execution of the task after pausing. The task or container is resumed by the runtime engine.
	SaveToXML	Infrastruttura. Saves information to an XML document.
	SetExpression	Infrastruttura. Assigns the specified expression to the property. Specify nullriferimento Null (Nothing in Visual Basic). to remove an existing expression from the property.
	SuspendExecution	Infrastruttura. Indicates that the executable needs to suspend. This method is called by the runtime engine.
	ToString	Ereditato da Object.
