FPCScheduledContentDownload Collection

The FPCScheduledContentDownload collection holds a set of FPCScheduledContentDownloadConfig objects that define individual content download jobs. This collection allows you to obtain a list of the content download jobs that are already defined, to retrieve the FPCScheduledContentDownloadConfig object for a specific job and access its properties, to define new content download jobs, and to remove existing jobs.

Content download jobs can run only if:

The Local Host network is configured to listen for requests from Web proxy clients (see the EnableWebProxyClients property of the FPCNetwork object representing the Local Host network).
There is a Web listener (an FPCWebListener object) that listens for requests from the Local Host network.
The Scheduled Download Jobs system policy configuration group is enabled (see the Enabled property of the FPCSystemPolicyConfigGroup object), or an access rule that allows HTTP traffic to the All Networks network set from the Local Host network is enabled.
The Microsoft Firewall service and the Microsoft ISA Server Job Scheduler service are running (see the FirewallServiceStatus and JobSchedulerServiceStatus properties of the applicable FPCServer object).
The Web proxy is enabled (see the Enabled property of the FPCApplicationFilter object representing the Web Proxy Filter add-in).

In addition, downloaded content can be stored in the ISA Server cache only if a cache drive with a size (CacheLimitInMegs) greater than zero is configured.

The FPCScheduledContentDownload collection is accessed through the ScheduledContentDownload property of the FPCCache object.

Inheritance

This object inherits from the FPCPersist object, which contains methods and properties related to the persistent storage of an object's data. They include methods for exporting the object's data to and importing it from an XML document.

Methods

The FPCScheduledContentDownload collection defines the following methods.

Method	Description
Add	Creates a new FPCScheduledContentDownloadConfig object in the collection and returns a reference to it.
Item	Retrieves the requested FPCScheduledContentDownloadConfig object from the collection.
Remove	Removes the specified FPCScheduledContentDownloadConfig object from the collection.

Properties

The FPCScheduledContentDownload collection has the following properties.

Property	Description
_NewEnum	Gets an enumerator object for the collection.
Count	Gets the number of FPCScheduledContentDownloadConfig objects in the collection.

Methods Inherited from FPCPersist

Name	Description
CancelWaitForChanges	Cancels the registration established by the WaitForChanges method (for use in C and C++ programming only).
CanImport	Returns a Boolean value that indicates whether the properties of the collection, its elements, and their subobjects can be imported from the specified XML document.
Export	Recursively writes the stored values of all the properties of the collection, its elements, and their subobjects to the specified XML document.
ExportToFile	Recursively writes the stored values of all the properties of the collection, its elements, and their subobjects to the specified XML file.
GetServiceRestartMask	Retrieves a 32-bit bitmask of the FpcServices enumerated type that specifies which services need to be restarted for currently unsaved changes to take effect.
Import	Recursively copies the values of all the properties of the collection, its elements, and their subobjects from the specified XML document to persistent storage.
ImportFromFile	Recursively copies the values of all the properties of the collection, its elements, and their subobjects from the specified XML file to persistent storage.
LoadDocProperties	Provides the XML document's properties so that you can know what information can be imported from the document.
Refresh	Recursively reads the values of all the properties of the collection, its elements, and their subobjects from persistent storage, overwriting any changes that have not been saved.
Save	Recursively writes the current values of all the properties of the collection, its elements, and their subobjects to persistent storage.
WaitForChanges	Registers to wait for an event indicating that the contents of the object have changed (for use in C and C++ programming only).

Properties Inherited from FPCPersist

Name	Description
PersistentName	Gets the persistent name of the collection. The persistent name of an object is a name that is unique for the object at the respective level of the COM object hierarchy.
VendorParametersSets	Gets an FPCVendorParametersSets collection that can hold sets of custom data for extending the collection.

Remarks

This collection implements the IFPCScheduledContentDownload interface.
