problem formatting dates from text fields.

[krishnakant Mane]

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.

Simplest is probably to do what many web-sites use for credit card
expiration dates... Ignore any pre-built date-time modules...

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?

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:

http://www.manning.com/rappin/

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 su*****@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
