            Bug ID: 37515
           Summary: Setting DateTime control display format via
                    DTM_SETFORMATA works, but DTM_SETFORMATW does not
                    work.
           Product: Wine
           Version: 1.7.30
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: comctl32
          Assignee: wine-bugs at winehq.org
          Reporter: wnalfl3737 at gmail.com
      Distribution: ---

If a native Windows DateTime (common) control is sent a DTM_SETFORMATW message,
it displays the following (wp is always NULL, and lp is LPWSTR) :

err:datetime:DATETIME_WindowProc unknown msg 1050 wp=00000000 lp=00406264

Both DTM_SETFORMATW (0x1050) and DTM_SETFORMATA (0x1005) are a variant of the
message DTM_SETFORMAT, which in turn is used by the macro "DateTime_SetFormat".

The only difference between the two messages is that DTM_SETFORMATW takes
lParam (the date format, MM/dd/yyyy for example) as an Unicode string, while
DTM_SETFORMATA takes lParam as an ASCII/native code page string.

(P.S. through I read that posting logs here instead of sth like pastebin is not
recommended, i posted it since it is only one line long :P)
