[Bug 7025] New: StgOpenStorage API function should not create a file if file does not exist

           Summary: StgOpenStorage API function should not create a file if
                    file does not exist
           Product: Wine
           Version: 0.9.28.
          Platform: PC-x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-files
        AssignedTo: wine-bugs(a)winehq.org
        ReportedBy: mikegardiner(a)bigpond.com


Comparing the behaviour of StgOpenStorage in Wine and WindowsXP,
Windows: StgOpenStorage calls CreateFileW with the creation parameter set to
OPEN_EXISTING, even if the file does not exist.
Wine: StgOpenStorage calls CreateFileW with the creation parameter set to
CREATE_NEW if the file does not exist.

This confuses an application that I am trying to get fully working (Orcad
Capture 9.2), because it expects the StgOpenStorage API to return an error if
the file does not exist. I removed the code in StgOpenStorage that creates the
file if it does not exist, so it now behaves as the Windows fn does, and this
fixed this particular bug in Orcad.
