i'm lost with ParseDate and FormatDate (wx2.9)

[Riccardo Cohen]

Hi
I don't know if I'm missing something, but it seems that ParseDate and 
FormatDate do not work correcly together.

this is a sample code :

   wxDateTime adate;
   wxString tmpd=wxT("01/06/2000");
   str+=wxString::Format(wxT("string is %s\n"),tmpd);
   adate.ParseDate(tmpd);
   str+=wxString::Format(wxT("Month is %d\n"),adate.GetMonth());
   tmpd=adate.FormatDate();
   str+=wxString::Format(wxT("Format is %s\n"),tmpd);
   adate.ParseDate(tmpd);
   str+=wxString::Format(wxT("Month is %d\n"),adate.GetMonth());
   tmpd=adate.FormatDate();
   str+=wxString::Format(wxT("Format is %s\n"),tmpd);

that produces :

string is 01/06/2000
Month is 0
Format is 06/01/2000
Month is 5
Format is 01/06/2000

The month and the day are exchanged
This does the same on windows and mac, and for locale french and english

I tried to use Format(wxT("%x")) and ParseFormat(wxT("%x")) :

   tmpd=wxT("01/07/2000");
   str+=wxString::Format(wxT("string is %s\n"),tmpd);
   adate.ParseFormat((const wxChar *)tmpd,wxT("%x"));
   str+=wxString::Format(wxT("Month is %d Year is 
%d\n"),adate.GetMonth(),adate.GetYear());
   tmpd=adate.Format(wxT("%x"));
   str+=wxString::Format(wxT("Format is %s\n"),tmpd);
   adate.ParseFormat((const wxChar *)tmpd,wxT("%x"));
   str+=wxString::Format(wxT("Month is %d Year is 
%d\n"),adate.GetMonth(),adate.GetYear());
   tmpd=adate.Format(wxT("%x"));
   str+=wxString::Format(wxT("Format is %s\n\n"),tmpd);

But there are many errors (see below). What is the best way to parse and 
format date using locale settings ?
