    problem formatting dates from text fields.

    hello all.
    thanks for the help and for pointing me to the proper url for wxpython
    related issues.
    I am so happy that I now have a very easy gui library that can do
    practically every thing with such ease (no flames intended but I was
    never at so much ease with java swing ).
    I however have a problem with dates.
    I am tired searching for some good tutorial that can explain the basic
    functionality of wx.datetime class and the datetime picker.
    I want to display the date in dd/mm/yyyy format and allow the user to
    change the dates.
    I then will like to take the value (the entire date) and put into a database.
    now this is my first question.
    the other problem is even more tough to solve with my given knowledge
    of wx.datetime and related classes.
    unfortunately the database given to me has a text field for date and
    the data is neetly entered.
    but when I get the data back from that text field I some how want to
    convert it back to actual date in the same dd/mm/yyyy format and send
    this as a value to my date time picker.
    how can I achieve this?
    thanking all.
    Krishnakant.

      Create three integer fields, make the first two drop-down lists
      pre-populated with days and months. And validate the results later (just
      to cover someone putting in 31 02 xxxx).

      My 2 cents worth:

      (1) this annoys the bejaysus out of data inputters who can type
      "31\t12" a lot faster than they can pick it out of two drop-down lists.

      (2) this would annoy the bejaysus out of data users if they were aware
      of the extent of off-by-one errors caused by using drop-down lists.

      Cheers,
      John

          You don't show us what format is used in the database, so there is
          nothing to base a conversion on. Is it year/month/day, month/day/year;
          months numeric or alpha (abbreviated or spelled out). Fields separated
          by space, comma, -, :, or /
          >
          the format in the text field is dd/mm/yyyy which is perfect for what I need.
          but the problem as I said is to get this text into a value that can
          fit into a date time picker.
          can this be done?

              Re: problem formatting dates from text fields.

              is there a soft copy of wxpython in action available for free download?
              I saw the book on my book store but since I am totally blind, I have
              to depend on soft copies.

                  It is not available for free, no. However, it is available in PDF form from
                  Manning's website:

                  wxPython in Action - Noel Rappin and Robin Dunn
                  http://www.manning.com/rappin/
                  wxPython in Action is a complete guide to the wxPython toolkit, containing a tutorial for getting started, a guide to best practices, and a reference to wxPython's extensive widget set. After an easy introduction to wxPython concepts and programming practices, the book takes an in-depth tour of when and how to use the bountiful collection of widgets offered by wxPython. All features are illustrated with useful code examples and reference tables are included for handy lookup of an object's properties, methods, and events. The book enables developers to learn wxPython quickly and remains a valuable resource for future work.


                  If their Yahoo store is not accessible via your web reader (I have no
                  experience, so I won't depend on it), you can email the publisher's customer
                  service at support@manning .com and I'm sure they will get the book to you in a
                  form you can read.

                      This annoyance can be maximised if, after the selection, a pop up dialog window
                      is displayed showing what was chosen, along with the following text:

                      "This is what you have chosen - Please indicate whether or not you wish to re
                      try"

                      - with the focus on the "yes" button.
                      and then, when "yes" is chosen, to start again without any attempt to remember
                      the previously entered values
