-description

The ProcessItem method provides additional functionality each time an item is processed. The application provides the implementation of the ProcessItem method.

-parameters

-param dwAcquireStage [in]

Specifies a double word value indicating whether this method is being called before or after processing an item. Must be one of: PAPS_PRESAVE, PAPS_POSTSAVE, or PAPS_CLEANUP.

Value	Description
PAPS_PRESAVE	Indicates that the method is being called before saving the acquired file. During PAPS_PRESAVE, pPhotoAcquireItem::GetProperty should be used to retrieve metadata from the original file, while new metadata to be written to the file should be added to pPropertyStore.
PAPS_POSTSAVE	Indicates that the method is being called after saving the acquired file.
PAPS_CLEANUP	Indicates that the user has canceled the acquire operation and any work done by the plug-in should be cleaned up.

-param pPhotoAcquireItem [in]

Pointer to an IPhotoAcquireItem object for the item being processed.

-param pOriginalItemStream [in]

Pointer to an IStream object for the original item. NULL if dwAcquireStage is PAPS_POSTSAVE.

-param pszFinalFilename [in]

The file name of the destination of the item. NULL if dwAcquireStage is PAPS_PRESAVE.

-param pPropertyStore [in]

The item's property store. NULL if dwAcquireStage is PAPS_POSTSAVE.
