function creates a new embedded object from the contents of a named file. If
the ProgID in the registration database contains the PackageOnFileDrop key, it
creates a package. If not, the function calls the GetClassFile
function to get the CLSID associated with the lpszFileName
parameter, and then creates an OLE 2-embedded object associated with that
CLSID. The rclsid
parameter of OleCreateFromFile
will always be ignored, and should be set to CLSID_NULL.
As for other OleCreateXxx
functions, the newly created object is not shown to the user for editing,
which requires a DoVerb
operation. It is used in to implement insert file operations, such as the
Create from File command in Word for Windows.
