Data

1. e32db

2. e32dbm

3. Contacts

4. Calendar

 

 

e32dbm

Simple Python dictionary

Very easy tuse

import e32dbm

 

simple = e32dbm.open(u"c:\\simple.db", 'c')

simple['cat'] = 'mouse'

simple['dog'] = 'sam' #values & keys must be strings

simple.sync()

for x in simple:

    print x

print simple['cat']

simple.close()

 

Methods & Details

See chapter 9 (pp 42-43) of API Reference for Python Series 60

Methods are subset of mapping methods

See http://docs.python.org/lib/typesmapping.html for explanation of methods

 

 

e32db

Uses subset of SQL

Compatible with C++ code

Used by e32dbm

import e32db

db = e32db.Dbms()

db_name = u"c:\\Books.db"

try:

    db.open(db_name)

except:

    db.create(db_name)

    db.open(db_name)

    create_books = u"CREATE TABLE books (title VARCHAR,

            author VARCHAR)"

    db.execute(create_books)

 

add_book = u"INSERT INTbooks (title, author) VALUES

                    ('%s','%s')"%('A Cat in the Hat', 'Dr Seuss')

db.execute(add_book)

all_books = e32db.Db_view()

all_books.prepare(db, u"SELECT * from books")

all_books.first_line()

 

for k in range(all_books.count_line()):

    all_books.get_line()

    print all_books.col(1)

    print all_books.col(2)

    all_books.next_line()

db.close()

Contacts

 

Classes

ContactDb - database of contact objects

Contact - represents a contact, contains fields

Possible Contact Fields

 

ContactField, contains attributes

7. label

8. value

9. type

10. location (none, work, home)

11. schema

 

 

Contact Example

import contacts

 

contacts = contacts.open()

new_person = contacts.add_contact()

new_person.add_field('first_name', value='Roger')

new_person.add_field('last_name', value='Whitney')

new_person.add_field('mobile_number', value='1111111111')

new_person.commit()

 

for k in contacts.keys():

    print contacts[k].find('first_name')[0].value

matches = contacts.find('Whitney')

print matches[0].find('last_name')[0].value

 

contacts.find( ) return list of contact objects

contactObject.find('field_name') returns list of contact fields

 

 

 

Networking

12. SMS text messages

13. Telephone

14. TCP/IP

15. Bluetooth

 

 

 

SMS

import messaging

 

messaging.sms_send('6165831978', u'Hello')

 

Simulator

16. Does not send message

17. Records the message

C:\Symbian\6.1\Series60\Epoc32\Winds\c\system\Mail

 

 

 

Phone Calls

import telephone

telephone.dial(u'6191111111')

 

Has no effect in simulator

 

Location

import location

 

country_code, network_code, area_code, cell_id = \

                                    location.gsm_location()

print country_code, network_code, area_code, cell_id

 

Fake data returned in simulator

 

 

 

TCP/IP

 

Uses standard Python networking modules

18. socket

http://docs.python.org/lib/module-socket.html

19. urllib

http://docs.python.org/lib/module-urllib.html

 

socket

low level access to network

Bluetooth support added

 

urllib

import urllib

 

page = urllib.urlopen(' http://www.eli.sdsu.edu/index.html' )

print page.read()

 

Simulator does not seem to access network
