           Summary: QueryPathOfRegTypeLib fails to locate typelib when
                    (major.minor) = (0xffff.0xffff)
           Product: Wine
           Version: 1.1.18
          Platform: Other
        OS/Version: other
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: oleaut32
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: focht at gmx.net


Hello,

oleauto32.QueryPathOfRegTypeLib() doesn't work correctly when (major.minor) =
(0xffff.0xffff).
These parameters are passed by .NET Framework/CLR when regasm.exe utility is
used to export and register typelibs from .NET assemblies.
E.g. something like this:

--- snip ---
$ wine regasm.exe foo.dll /codebase /tlb
--- snip ---

WINEDEBUG=+tid,+seh,+ole,+reg

--- snip ---

MSDN doesn't mention such condition so this obviously needs some test case to
find out what logic is used to select the best match (first? last? lowest?
highest?).

dll/oleaut32/typelib.c:find_typelib_key() needs to be fixed accordingly.
"wMaj" needs to be made an "out" parameter too to actually return best matching
maj.min pair

With this part fixed it goes further - only to stumble into next bug ;-)

Regards
