Return value

Remarks

The desktop item's identification is returned in the dwID member of the COMPONENT structure that is returned from the IActiveDesktop::GetDesktopItem method. This identification is only valid until the IActiveDesktop::ApplyChanges method is called. Applications that must retrieve the same desktop item consistently should enumerate the desktop items using the IActiveDesktop::GetDesktopItem and IActiveDesktop::GetDesktopItemCount methods.
