Provides access to members that manage the life of a workspace extension.
Members
| Name | Description | |
|---|---|---|
 |
Init | Initializes the extension, passing in a reference to its workspace helper. |
|
Shutdown | Informs the extension that its workspace helper (and workspace) are going away. |
IWorkspaceExtensionControl.Init Method
Initializes the extension, passing in a reference to its workspace helper.
Public Sub Init ( _
ByVal WorkspaceHelper As IWorkspaceHelper _
)
public void Init (
IWorkspaceHelper WorkspaceHelper
);
IWorkspaceExtensionControl.Shutdown Method
Informs the extension that its workspace helper (and workspace) are going away.
Public Sub Shutdown ( _
)
public void Shutdown (
);
Remarks
The Shutdown method informs the workspace extension that the workspace has been released by all clients and is about to go away. In response, the workspace extension should release its reference on the workspace helper. Any subsequent calls by the application to the workspace extension should return an error.

Remarks
IWorkspaceExtensionControlis a mandatory interface that must be supported by all workspace extensions. This interface is used by the workspace to manage the lifetime of the workspace extension. The workspace cocreates the workspace extension and calls the Initmethod handing it back a reference to the workspace via the workspace helper argument. The workspace helper implements a weak reference on the workspace. The extension can keep a strong reference on the workspace helper (for example, in a member variable) but should not keep a strong reference on the workspace. Extensions should get the workspace from the workspace helper in order to make any method calls on the workspace and release the reference after making the method calls.
The Shutdownmethod informs the workspace extension that the workspace has been released by all clients and is about to go away. In response the workspace extension should release its reference on the workspace helper. Any subsequent calls by the application to the workspace extension should return an error.
The IWorkspaceExtensionControl interface does not need to be considered by developers working with network datasets.
