Your varDocument does not contain a VT_DISPATCH object.  It probably contains nothing (VT_EMPTY).

 

Shell.Explorer will not return a valid document until you have opened a valid URL or loaded a valid file.

 

Try calling the GoHome method or the Navigate method first.

 

See org.eclipse.swt.win32.ole for an example.
