For an application filter to work on a Forefront TMG computer, its dynamic-link library (DLL) and other necessary files must be copied to the computer, an object representing it must be created in the FPCApplicationFilters collection for the computer's array, and it must be registered as an extension of the Microsoft Firewall service on the computer by including a reference to it in the computer's InstalledApplicationFilters property. When the Firewall service starts, it creates an instance of the filter object for each application filter that is registered on the Forefront TMG computer and enabled.
When the Add method of this collection is called on an array member to register an application filter in an array, a reference to the new FPCApplicationFilter object is automatically created in the FPCRefs collection held in the InstalledApplicationFilters property of the local Forefront TMG computer.
When an enterprise with central array management is deployed, objects representing application filters can also be added to the FPCApplicationFilters collection in the enterprise configuration by calling the Add method of this collection. Creating an object for an application filter in the enterprise FPCApplicationFilters collection is optional, but provides several benefits. For more information about registering application filters, see Filter Setup.

This collection 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.
The FPCApplicationFilters collection defines the following methods.
Creates a new FPCApplicationFilter object in the collection and returns a reference to it.
Retrieves the requested FPCApplicationFilter object from the collection.
Removes the specified FPCApplicationFilter object from the collection.
The FPCApplicationFilters collection defines the following properties.
Gets an enumerator object for the collection.
Gets the number of FPCApplicationFilter objects in the collection.
|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 and its elements can be imported from the specified XML document.|
|Export||Writes the stored values of all the properties of the collection and its elements to the specified XML document.|
|ExportToFile||Writes the stored values of all the properties of the collection and its elements 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||Copies the values of all the properties of the collection and its elements from the specified XML document to persistent storage.|
|ImportFromFile||Copies the values of all the properties of the collection and its elements 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||Reads the values of all the properties of the collection and its elements from persistent storage, overwriting any changes that have not been saved.|
|Save||Writes the current values of all the properties of the collection and its elements 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).|
|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.|
|VendorParameterSets||Gets an FPCVendorParametersSets collection that can hold sets of custom data for extending the collection.|
This object implements the IFPCApplicationFilters interface.
|Client||Requires Windows Vista or Windows XP.|
|Server||Requires Windows Server 2008.|
|Version||Requires Forefront Threat Management Gateway (TMG).|
