A semi connected world

• Cost
• Placing a phone call (or a Wifi connection)
• Bandwidth
• GSM is 14.4 kbs, GPRS 28.8kbs
• Infrastructure
• The worker up in the mountain, the sailor out in
  the ocean
• Power shortage, network downtime

Developing for disconnection

• Applications need to run on the device
• Small footprint programming
• Low memory
• Low performance
• No hard disk
• Device specifics
• Platform targets (CPU an OS)
• Various form factors
• Various functionnality (telephony, connectivity,
  phonebook / contacts, etc)

11
I Wish I Could

• Have a RAD environment
• Abstraction of device specifics
• Develop once, deploy everywhere
• Use familiar programming and object models

12

Demo

• My phone is smart

21
What About Device Specific Functionality !

• Telephony
• SMS Messaging
• Accessing PIM Data
• Accessing the SIM card
• BlueTooth
• Printer drivers

22
P/Invoking the genie

• Telephony
• P/Invoke to RequestMakeCall or PhoneMakeCall
• SMS Messaging
• P/Invoke to messaging APIs for sending
• Receiving requires a native component to receive
  the message then pass it out of process to
  managed application
• Accessing PIM Data
• P/Invoke to Pocket Outlook Object Model
• Accessing the SIM card
• P/Invoke to native SIM Toolkit APIs

23
Demo

• Making a phone call,
• Sending SMS messages

24
After my 3 wishes

• How do I deal with ActiveX components
• Drivers (Printer etc.)
• What about embeded components
• P/Invoke is too heavy, too inelegant
• Can I simply have COM-Interop (wrapping)
• What about games and graphics

Pocket OutlookVisual Studio 2005
Imports Microsoft.WindowsMobile.PocketOutlook '
Display users contacts in a ListBox Dim
myItemStore As New ItemStore Dim ContactsListBox
As System.Windows.Forms.ListBox ContactsListBox.Da
taSource myItemStore.Contacts.Items ContactsList
Box.DisplayMember "FileAs" ' Modify the
currently selected contact in the ListBox Dim c
As Contact CType(ContactsListBox.SelectedItem,
Contact) c.CompanyName Microsoft c.Title
Program Manager ' Save the contact c.Update()

TelephonyVisual Studio 205
using Microsoft.WindowsMobile.PocketOutlook using
Microsoft.WindowsMobile.Telephony Phone
myPhone new Phone() // If the radio is on,
make the call if (myPhone.RadioState
Available) VoiceCall c new
VoiceCall("2065555555", true)
c.Talk() // Display call information from
Call Log // Use Pocket Outlook APIs to display
contact Info foreach (VoiceCall vc in
myPhone.CallLog.AllVoiceCalls)
MessageBox.Show("Call 0 1",
vc.Contact.FirstName, c.Number)
