'Usage
Dim instance As Executables

public sealed class Executables : DTSReadOnlyCollectionBase

The Executables type exposes the following members.

Properties

	Name	Description
	Count	Gets the number of elements contained in the DTSReadOnlyCollectionBase instance. (Inherited from DTSReadOnlyCollectionBase.)
	IsSynchronized	Gets a value that indicates whether access to the DTSReadOnlyCollectionBase is synchronized (thread-safe). (Inherited from DTSReadOnlyCollectionBase.)
	Item	Returns an Executable object from the collection.
	SyncRoot	Gets an object that can be used to synchronize access to the DTSReadOnlyCollectionBase. (Inherited from DTSReadOnlyCollectionBase.)

	GetHashCode	(Inherited from Object.)
	GetManagedEnumerator	Infrastructure. (Inherited from DTSReadOnlyCollectionBase.)
	GetType	(Inherited from Object.)

Remarks

All containers, including the Package, Sequence, TaskHost, DtsEventHandler, ForLoop, and ForEachLoop, have an Executables property that contains the collection of executable objects processed by the run-time engine during execution of the container. The order of execution of the objects in the collection is determined by the PrecedenceConstraints inherited and implemented by the containers. You can add tasks to a package and set their properties graphically using the SSIS Designer, or programmatically using the run-time object model to build the package in Microsoft Visual Basic, Microsoft Visual C++, or C#. For more information, see Designing and Implementing Packages (Integration Services) and Adding Tasks to a Control Flow.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
