           Summary: DlgDirListComboBox does not fail properly on bad path
                    spec argument
           Product: Wine
           Version: 0.9.35.
          Platform: Other
        OS/Version: other
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-user
        AssignedTo: wine-bugs(a)winehq.org
        ReportedBy: lupien(a)physique.usherbrooke.ca


When a path spec is given that is not a directory and that does not contain any
* or ? then DlgDirListComboBox should fail and return False. Currently it can
return true. See http://msdn2.microsoft.com/en-us/library/ms673323.aspx 

The problem for me occured in a win31 program extended to 32bit by watcom. The
program relies on a failure in the routine to open file from a fancy file
manager. The non failing prevented any file to be loaded. The call is with the
DDL_DIRECTORY|DDL_EXCLUSIVE flags.

An exemple:
 Let a directory "c:\test" contain many files including one subdirectory
("c:\test\testsub") then  a call to DlgDirListComboBox with path spec of
 "c:\\test", or "c:\\test\\" or "c:\\test\\*.*" should all return true and
produce the same listing. But a call with "c:\\test\\test.c" should fail (wether
or not test.c exist because the file spec does not contain any * or ?. 
I checked this behavior under windows XP. Under the current wine I tested
(0.9.35 from fedora core 5 extras) this does not fail.

The actual problem is in the DIALOG_DlgDirListW function of
dlls/user32/dialog.c. I will attach a patch that produces the correct behavior
(compared to XP) and fixes my problem.


A related problem is that under windows (at least XP) when calling with 
only the DDL_DRIVES attribute produce the same result as calling with DDL_DRIVES
| DDL_EXCLUSIVE but this is not the case under wine. My program is filling a box
with files and drives but it is supposed to contain only drives. The same
happends when sending a message to the listbox directly so I attach a patch that
fixes the problem in the LISTBOX_Directory function of ddls/user32/listbox.c.
