IFileViewer::ShowInitialize
HRESULT ShowInitialize(
    LPFILEVIEWERSITE lpfsi		
   );		
Allows a file viewer to determine whether it can display a file and, if it can, to perform initialization operations before showing the file.
Returns NOERROR if successful, or an OLE-defined error value otherwise.

lpfsi
Address of an IFileViewerSite interface. A file viewer uses this interface to retrieve the handle to the current pinned window or to specify a new pinned window.

The shell calls this method before the IFileViewer::Show method. The shell specifies the name of the file to display by calling the file viewer's IPersistFile::Load method.
ShowInitialize must perform all operations that are prone to failure so that if it succeeds, IFileViewer::Show will not fail.
