Remarks

The OleCreateFromFile 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 to implement insert file operations.
