Defines a control flow that is a subset of the package control flow. Use Sequence containers to group the package into multiple separate control flows that each contain one or more tasks and containers that run within the overall package control flow. This class cannot be inherited.

Fields

m_executable

The executable.

(Inherited from Executable)

Properties

CreationName	Returns the string that is used to create an instance of the DtsContainer object. This property is read-only. (Inherited from DtsContainer)
DebugMode	Gets or sets a Boolean that indicates whether the DtsContainer object is in debug mode and whether it should fire the OnBreakpointHit(IDTSBreakpointSite, BreakpointTarget) event while running. (Inherited from DtsContainer)
DelayValidation	Gets or sets a Boolean that indicates whether validation of the task is delayed until run time. The default value is false. (Inherited from DtsContainer)
Description	Gets or sets the description of the DtsContainer object. (Inherited from DtsContainer)
Disable	A Boolean that indicates if the DtsContainer object is disabled. (Inherited from DtsContainer)
DisableEventHandlers	Gets or sets a Boolean that indicates whether the event handlers on task are disabled. (Inherited from EventsProvider)
EventHandlers	Returns a collection of event handler objects. This field is read-only. (Inherited from EventsProvider)
EventInfos	Returns a collection of EventInfo objects. This field is read-only. (Inherited from EventsProvider)
Executables	Returns a collection of executable objects processed by the run-time engine during execution of this Sequence container. This property is read-only.
ExecutionDuration	Returns a value that indicates the amount of time that the container spent in execution, in milliseconds. This property is read-only. (Inherited from DtsContainer)
ExecutionResult	Returns a value that indicates the success or failure of the execution of the DtsContainer object. (Inherited from DtsContainer)
ExecutionStatus	Returns a value that indicates the current status of the execution of the DtsContainer object at the time of the call. (Inherited from DtsContainer)
FailPackageOnFailure	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. (Inherited from DtsContainer)
FailParentOnFailure	Gets or sets a `Boolean` that defines whether the parent container fails when a child container fails. (Inherited from DtsContainer)
ForcedExecutionValue	If the ForceExecutionValue property is set to True, gets or sets a value that specifies the optional execution value that the package returns. (Inherited from DtsContainer)
ForceExecutionResult	Gets or sets a DTSForcedExecResult enumeration value that specifies the forced execution result of the container. (Inherited from DtsContainer)
ForceExecutionValue	Gets or sets a Boolean that indicates whether the execution value of the container should be forced to contain a particular value. (Inherited from DtsContainer)
HasExpressions	Gets a value that indicates whether the specified Sequence has expressions.
ID	Returns the ID, which is a GUID, of the DtsContainer. The value is read-only. (Inherited from DtsContainer)
IsDefaultLocaleID	A Boolean that indicates whether the container uses the default locale. This property is read-only. (Inherited from DtsContainer)
IsolationLevel	Gets or sets the isolation level of the transaction in the DtsContainer object. (Inherited from DtsContainer)
LocaleID	Gets or sets an Integer that indicates the Microsoft Win32® localeID to use when the DtsContainer object is executed. (Inherited from DtsContainer)
LogEntryInfos	Returns a LogEntryInfos object. This property is read-only. (Inherited from DtsContainer)
LoggingMode	Gets or sets a valid value from the DTSLoggingMode enumeration that indicates the logging mode of the container. (Inherited from DtsContainer)
LoggingOptions	Returns an object that contains properties that indicates the filtering and logging resource for containers. This property is read-only. (Inherited from DtsContainer)
MaximumErrorCount	Gets or sets an Integer value that indicates the maximum number of errors that can occur before the DtsContainer object stops running. (Inherited from DtsContainer)
Name	Gets or sets the name of the DtsContainer. (Inherited from DtsContainer)
Parent	Returns the parent container. The value is read-only. (Inherited from DtsContainer)
PrecedenceConstraints	Returns a collection of PrecedenceConstraint objects that describe the precedence constraints that link container-level containers and tasks into an ordered control flow
Properties	Returns a collection of DtsProperty objects that contain properties relating to the sequence container.
Site	Gets or sets the site for the container. (Inherited from DtsContainer)
StartTime	Returns the time that the container began execution. This property is read-only. (Inherited from DtsContainer)
StopTime	Returns the time that the container ended execution. This property is read-only. (Inherited from DtsContainer)
SuspendRequired	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. (Inherited from DtsContainer)
TransactionOption	Gets or sets a DTSTransactionOption enumeration value that indicates whether the container participates in transactions. (Inherited from DtsContainer)
VariableDispenser	Returns a VariableDispenser object so variables associated with the container can be locked. (Inherited from DtsContainer)
Variables	Returns a collection that contains the variables associated with this container. This property is read-only. (Inherited from DtsContainer)

Methods

AcceptBreakpointManager(BreakpointManager)	This method is called by the run-time engine when a task or container is created, and passes it a BreakpointManager manager to allow the task to create, remove, and check the status of breakpoints. This method is called by the runtime and is not used in code. (Inherited from DtsContainer)
Dispose()	Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources. (Inherited from DtsContainer)
Equals(Object)	Determines whether two object instances are equal. (Inherited from DtsObject)
Execute(Connections, Variables, IDTSEvents, IDTSLogging, Object)	Runs the application, container, or package as part of a package workflow. (Inherited from DtsContainer)
GetExecutionPath()	Returns the execution path of the current sequence.
GetExpression(String)	Returns a String that contains the expression for the specified property. Null means no expression is assigned.
GetHashCode()	Returns the hash code for this instance. (Inherited from DtsObject)
GetPackagePath()	Returns the path of the package that the sequence container is a part of.
LoadFromXML(XmlNode, IDTSEvents)	This method is not callable by your application code. To load a package saved as .xml, use the LoadPackage(String, IDTSEvents) method. (Inherited from DtsContainer)
ResumeExecution()	Resumes execution of the task after pausing. The task or container is resumed by the runtime engine. (Inherited from DtsContainer)
SaveToXML(XmlDocument, XmlNode, IDTSEvents)	This method is not callable by your application code. To save a package as .xml, use the SaveToXml(String, Package, IDTSEvents) method. (Inherited from DtsContainer)
SetExpression(String, String)	Assigns the specified expression to the property. Specify null to remove an existing expression from the property.
SetWrappedExecutable(IDTSExecutable100)	Returns the wrapped executable object. (Inherited from EventsProvider)
SuspendExecution()	Called when the executable needs to suspend. This method is called by the runtime engine. (Inherited from DtsContainer)
Validate(Connections, Variables, IDTSEvents, IDTSLogging)	Allows the container to determine if it contains invalid settings that will prevent it from executing successfully. (Inherited from DtsContainer)

Events
