FPCApplicationFilter Object

The FPCApplicationFilter object represents a single application filter. Application filters work with the Microsoft Firewall service to intercept and process data. Application filters can access the data stream or datagrams associated with a session within the Firewall service. The filters are registered with the Firewall service and act in response to events detected by the service. An application filter can perform protocol-specific or system-specific tasks, such as authentication and checking for viruses.

The application filters that are associated with a protocol are specified by including references to the applicable FPCApplicationFilter objects in the FPCRefs collection held in the ApplicationFilters property of the FPCProtocolDefinition object.

The application filters that are installed on a Forefront TMG computer are registered with the Firewall service by including references to the applicable FPCApplicationFilter objects in the FPCRefs collection held in the InstalledApplicationFilters property of the FPCServer object.

The FPCApplicationFilter object is an element of an FPCApplicationFilters collection, and a new object representing an application filter can be created by calling the Add method of this collection.

Version	Gets or sets the vendor-supplied version of the application filter.

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 object's properties can be imported from the specified XML document.
Export	Writes the stored values of all of the object's properties to the specified XML document.
ExportToFile	Writes the stored values of all of the object's properties 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 of the object's properties from the specified XML document to persistent storage.
ImportFromFile	Copies the values of all of the object's properties 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 of the object's properties from persistent storage, overwriting any changes that have not been saved.
Save	Writes the current values of all of the object's properties 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 object. 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 object that can hold sets of custom data for extending the object.
