IFPCPersist::Import[C++] | FPCPersist.Import [Visual Basic]

Internet Security and Acceleration Server 2004/2006 SDK

The Import method recursively copies the values of all the properties of the object and of its subobjects from the specified XML document to persistent storage. For a collection, the method also imports all of its elements and their properties from the XML document. This method also writes any unsaved configuration changes that were made before the method was called to persistent storage.


HRESULT Import(
  IUnknown* pDocument,
  long OptionalData,
  BSTR EncryptionPassword,
  VARIANT_BOOL CleanCollections,
  VARIANT_BOOL fResetRequiredServices,
  VARIANT_BOOL fReloadConfiguration );

Parameters

pDocument
[in] Pointer to the IUnknown interface on the DOMDocument object from which the information will be imported.
OptionalData
[in] A 32-bit integer value that specifies what optional data to include in the import. This value is a bitwise combination of values from the FpcExportImportOptionalData enumerated type. The bits set should not call for the inclusion of optional data in the import that were not included in the export.
EncryptionPassword
[in, optional] BSTR that specifies a password for importing encrypted information. This parameter is an empty string by default. The password is required if the export was performed using an encryption password.
CleanCollections
[in, optional] Boolean value that indicates whether to remove existing objects that are not included in the XML document. The default value is VARIANT_FALSE. If this parameter is set to VARIANT_TRUE in a call to the Import method on any interface other than the IFPCArray interface, the call will fail.
fResetRequiredServices
[in, optional] Boolean value that indicates whether to restart the services that need to be restarted for the changes to take effect. The default value is VARIANT_FALSE.
fReloadConfiguration
[in, optional] Boolean value that indicates whether the call will return only after ISA Server has reloaded the saved configuration with the current changes from persistent storage. The default value is VARIANT_TRUE. In Enterprise Edition, this parameter is ignored.

Return Values

This method returns S_OK if the call is successful; otherwise, it returns an error code.

Remarks

Any version of the XML DOM document object from Microsoft XML 4.0, XML 3.0, and XML 2.0 can be used.

Imported configuration changes are applied only after the new settings are written to persistent storage and reloaded to the services that use them. Most changes can be applied dynamically without restarting any services. However, some changes can take effect only after the Microsoft Firewall service is restarted. For more information, see Restarting Services After Configuration Changes.

ISA Server maintains a bitmask that specifies which services need to be started for the unsaved configuration changes to take effect. This bitmask can be retrieved by calling the GetServiceRestartMask method. Calling the Import method clears all of the bits in this bitmask even if the fResetRequiredServices parameter is set to VARIANT_FALSE.

In Standard Edition, if the fReloadConfiguration parameter is set to VARIANT_FALSE the current values of the object's properties will be written to persistent storage without updating the configuration being used by the ISA Server services. The configuration used by each service will not be updated until the service is restarted.

In Enterprise Edition, calls to this method return only after the information has been written to a Configuration Storage server. If the Firewall service needs to be restarted to apply changes, it will be restarted on each ISA Server computer only after the changes are retrieved from a Configuration Storage server and written to the locally stored configuration.

Parameters

pDocument
[in] Reference to the DOMDocument30 object from which the information will be imported.
OptionalData
[in] A 32-bit integer value that specifies what optional data to include in the import. This value is a bitwise combination of values from the FpcExportImportOptionalData enumerated type. The bits set should not call for the inclusion of optional data in the import that were not included in the export.
EncryptionPassword
[in, optional] String that specifies a password for importing encrypted information. This parameter is an empty string by default. The password is required if the export was performed using an encryption password.
CleanCollections
[in, optional] Boolean value that indicates whether to remove existing objects that are not included in the XML document. The default value is False. If this parameter is set to True in a call to the Import method on any object other than the FPCArray object, the call will fail.
fResetRequiredServices
[in, optional] Boolean value that indicates whether to restart the services that need to be restarted for the changes to take effect. The default value is False.
fReloadConfiguration
[in, optional] Boolean value that indicates whether the call will return only after ISA Server has reloaded the saved configuration with the current changes from persistent storage. The default value is True. In Enterprise Edition, this parameter is ignored.

Return Values

This method has no return values. If the call is unsuccessful, an error is raised that can be intercepted by using an error handler.
