4. Here’s What We’ll Cover Lots of Brand New Managed APIs Only for Windows Mobile 5.0.NET Compact Framework 1.0 or 2.0 CapabilitiesUsage Common mistakes Lots of code snippets

5. Initiate Calls With Phone.Talk Get properties and events through the State & Notification Broker Dim phone As New Phone phone.Talk( “425-555-1212” )

6. Let’s Talk

7. Microsoft.WindowsMobile Namespace Summary WindowsMobile.PocketOutlook Edit Contacts, Appointments, and Tasks Control the Messaging application Send SMS & email messages Intercept incoming SMS messages WindowsMobile.Status Query 100+ system properties Get notified of changes WindowsMobile.Configuration Configuration Manager WindowsMobile.Telephony Initiate phone calls WindowsMobile.Forms Contact Picker Dialog Picture Picker Dialog Camera Capture Dialog

8. Integrating With Outlook Mobile

9. It All Starts At OutlookSession OutlookSession outlook = new OutlookSession(); int contactCount = outlook.Contacts.Items.Count;

10. Folders And Collections One folder per type Each has a collection Enumerate items Check capabilities Sort & Filter Add & Remove ListChanged event

11. Appointments, Contacts, And Tasks Lots of properties and events Don’t forget Update() OutlookSession outlook = new OutlookSession(); Contact me = new Contact(); me.FullName = “Gaurav”; outlook.Contacts.Items.Add( me ); // <-- Saved me.JobTitle = “DE”; me.Update(); // <-- Saved

12. Managed POOM: Working with Contacts

13. Appointment And Task Can Be Recurring Recurrence Type Properties to Use Example DailyInterval Every 4 days Weekly Interval DaysOfWeekMask Every Monday and Tuesday Monthly Interval DayOfMonth Every 3 months MonthlyByNumber Interval DaysOfWeekMask Instance Second Friday of each month Yearly DayOfMonth MonthOfYear May 10 th of each year YearlyByNumber DaysOfWeekMask Instance MonthOfYear Second Tuesday in May of each year (All) PatternStartDate PatternEndDate NoEndDate

14. Items Can Be Shown In Outlook Mobile With ShowDialog Appointment appt = new Appointment(); appt.Subject = "Launch Windows Mobile 5.0!"; appt.AllDayEvent = true; appt.Start = new DateTime(2005, 5, 10); outlook.Appointments.Items.Add(appt); appt.ShowDialog();

15. Add Your Own Properties To PIM Items Contact myCustomer; //... if(!myCustomer.Properties.Contains(“Employee ID”)) { myCustomer.Properties.Add("Employee ID", typeof(string)); } myCustomer.Properties["Employee ID"] = "ABC1234"; 1. See if the property has been defined 2. If not, define it 3. Use it

16. Working With Item IDs string idString; // … Read idString from a file, registry, or database int idNumber = Int32.Parse( idString ); ItemID id = new ItemID( idNumber ); Contact c = new Contact( id ); Store references to items by their ID Retrieve items by their ID Contact c; // … string idString = c.ItemID.ToString();

17. Sending E-Mail And SMS SmsMessage msg = new SmsMessage(); msg.To.Add( new Recipient(“555-1212")); msg.Body = “Hello World!"; msg.Send();

18. Contacts Are Not Recipients Contact myCustomer; //... EmailMessage msg = new EmailMessage(); msg.To.Add( myCustomer ); // Won’t compile! msg.To.Add( new Recipient( myCustomer.Email2Address ) ); // OK

19. Managed POOM: Working with Messaging

20. Control The Messaging Application Display the compose form Display the inbox Initiate synchronization

21. Create rich mobile apps by intercepting SMS messages

22. Intercept SMS Messages In Managed Code MessageInterceptor sms; void Form_Load(... ) { sms = new MessageInterceptor(); //... Set optional properties here sms.MessageReceived += new EventHandler(sms_MessageReceived); } void sms_MessageReceived(...) { //... Handle incoming message }

23. Specify What Happens to Intercepted Messages MessageInterceptor sms; void Form_Load(... ) { sms = new MessageInterceptor(); sms.InterceptionAction = InterceptionAction.NotifyAndDelete; sms.MessageReceived += new EventHandler(sms_MessageReceived); } void sms_MessageReceived(...) { //... Handle incoming message }

24. Intercept SMS Messages In Native Code //================================================================= // MonitorThread - Monitors event for timer notification // DWORD WINAPI MonitorThread (PVOID pArg) { TEXT_PROVIDER_SPECIFIC_DATA tpsd; SMS_HANDLE smshHandle = (SMS_HANDLE)pArg; PMYMSG_STRUCT pNextMsg; BYTE bBuffer[MAXMESSAGELEN]; PBYTE pIn; SYSTEMTIME st; HANDLE hWait[2]; HRESULT hr; int rc; DWORD dwInSize, dwSize, dwRead = 0; hWait[0] = g_hReadEvent; // Need two events since it isn't hWait[1] = g_hQuitEvent; // allowed for us to signal SMS event. while (g_fContinue) { rc = WaitForMultipleObjects (2, hWait, FALSE, INFINITE); if (!g_fContinue || (rc != WAIT_OBJECT_0)) break; // Point to the next free entry in the array pNextMsg = &g_pMsgDB->pMsgs[g_pMsgDB->nMsgCnt]; // Get the message size hr = SmsGetMessageSize (smshHandle, &dwSize); if (hr != ERROR_SUCCESS) continue; // Check for message larger than std buffer if (dwSize > sizeof (pNextMsg->wcMessage)) { if (dwSize > MAXMESSAGELEN) continue; pIn = bBuffer; dwInSize = MAXMESSAGELEN; } else { pIn = (PBYTE)pNextMsg->wcMessage; dwInSize = sizeof (pNextMsg->wcMessage); } // Set up provider specific data tpsd.dwMessageOptions = PS_MESSAGE_OPTION_NONE; tpsd.psMessageClass = PS_MESSAGE_CLASS0; tpsd.psReplaceOption = PSRO_NONE; tpsd.dwHeaderDataSize = 0; // Read the message hr = SmsReadMessage (smshHandle, NULL, &pNextMsg- >smsAddr, &st, (PBYTE)pIn, dwInSize, (PBYTE)&tpsd, sizeof(TEXT_PROVIDER_SPECIFIC_DATA), &dwRead); if (hr == ERROR_SUCCESS) { // Convert GMT message time to local time FILETIME ft, ftLocal; SystemTimeToFileTime (&st, &ft); FileTimeToLocalFileTime (&ft, &ftLocal); FileTimeToSystemTime (&ftLocal, &pNextMsg->stMsg); // If using alt buffer, copy to std buff if ((DWORD)pIn == (DWORD)pNextMsg->wcMessage) { pNextMsg->nSize = (int) dwRead; } else { memset (pNextMsg->wcMessage, 0, sizeof(pNextMsg->wcMessage)); memcpy (pNextMsg->wcMessage, pIn, sizeof(pNextMsg->wcMessage)-2); pNextMsg->nSize = sizeof(pNextMsg->wcMessage); } // Increment message count if (g_pMsgDB->nMsgCnt < MAX_MSGS-1) { if (g_hMain) PostMessage (g_hMain, MYMSG_TELLNOTIFY, 1, g_pMsgDB->nMsgCnt); g_pMsgDB->nMsgCnt++; } } else { ErrorBox (g_hMain, TEXT("Error %x (%d) reading msg"), hr, GetLastError()); break; } SmsClose (smshHandle); return 0; }

25. Making use of SMS interception

26. Create smart mobile apps with the State & Notification Broker

27. Why Is This So Hard? Problems Different APIs for querying different properties Different change notification mechanisms for different properties Many properties not exposed (especially in.NET CF) No standard way for OEMs and ISVs to expose their own properties

28. State And Notification Broker Strategy 1. Placement of useful information in documented registry locations 2. Native APIs to get notified of changes to any registry value 3. Managed wrapper around native APIs

29. State And Notification Broker Design Registry Interesting Values SNAPI.hRegExt.h Microsoft.WindowsMobile.Status

30. There Are Over 100 System Properties Power & Battery Appointments Media Player ConnectivityActiveSyncMessagingTelephonyHardwareTasksShell

31. Get Change Notifications 1. Create a SystemState object 2. Attach an event handler SystemState callerId = new SystemState( SystemProperty.PhoneIncomingCallerContact); callerId.Changed += new EventHandler(callerId_Changed); void callerId_Changed(object sender, ChangeEventArgs e) { Contact caller = (Contact)callerId.CurrentValue; //... }

32. Two Ways To Query For Current Values 1. Static Strongly typed, quick and easy 2. Dynamic Contact c = SystemState.PhoneIncomingCallerContact; SystemState.PhoneIncomingCallerContact; SystemState callerId = new SystemState( SystemProperty.PhoneIncomingCallerContact); SystemProperty.PhoneIncomingCallerContact); Contact c = (Contact)callerId.CurrentValue;

33. The State And Notification Broker Is Extensible Publish your own state Get notified of changes to any registry value

34. Get Notified While Your Application Is Not Running Can be used for SMS Interception State and Notification Broker When a change occurs 1. Windows Mobile launches the application 2. Application hooks up an event hander 3. Event is fired

35. SystemState missedCall; void Form_Load( … ) { if(!SystemState.IsApplicationLauncherEnabled(“MyApp.MissedCall”)) { missedCall = new SystemState( SystemProperty.PhoneMissedCall ); missedCall.EnableApplicationLauncher( “MyApp.MissedCall” ); } else { SystemState missedCall = new SystemState(“MyApp.MissedCall”); } missedCall.Changed += new EventHandler( missedCall_Changed ); } App Launching With The State & Notification Broker

36. MessageInterceptor sms; void Form_Load( … ) { if(!MessageInterceptor.IsApplicationLauncherEnabled(“MyApp.SMS”)) { sms = new MessageInterceptor(); sms.EnableApplicationLauncher( “MyApp.SMS” ); } else { MessageInterceptor sms = new SystemState(“MyApp.SMS”); } sms.MessageReceived += new EventHandler( sms_MessageReceived ); } App Launching With The SMS Interception

37. Conditions Prevent Unnecessary Notifications Very important for app-launching notifications! Comparison Types: String Equal, NotEqual, StartsWith, EndsWith, Contains Integer Equal, NotEqual, Greater, GreaterOrEqual, Less, LessOrEqual Binary Not supported

38. Setting Conditions With The State & Notification Broker SystemState missedCall; void Form_Load( … ) { // … missedCall = new SystemState( SystemProperty.PhoneMissedCall ); missedCall.ComparisonType = StatusComparisonType.Equal; missedCall.ComparisonValue = true; missedCall.Changed += new EventHandler( missedCall_Changed ); }
