[Now Supported on Windows NT]
Allows a file viewer to determine whether it can display a file and, if it can, to perform initialization operations before showing the file.
The shell calls this member function before the IFileViewer::Show member function. The shell specifies the name of the file to display by calling the file viewer's IPersistFile::Load member function.
IFileViewer::ShowInitialize must perform all operations that are prone to failure so that if it succeeds, IFileViewer::Show will not fail.
HRESULT ShowInitialize(
IFileViewer FAR *pFileViewer, | |
LPFILEVIEWERSITE lpfsi | |
); |
Parameters
pFileViewer
Address of the IFileViewer interface. In C++, this parameter is implicit.
lpfsi
Address of a IFileViewerSite interface. A file viewer uses this interface to retrieve the handle of the current pinned window or to specify a new pinned window.
Return Values
Returns the NOERROR value if successful or an OLE-defined error value otherwise.
