Create your own web browser on your SmartPhone
Windows Mobile 5.0 comes with a Web Browser (v6 is due out any day now). It runs on Pocket PCs and SmartPhones. That browser only allows one web page to show at a time: to show another page, you have to navigate away from the current page. I created a web browser for my first SmartPhone over a year ago that allows you to open multiple web pages.
If you have Visual Studio 2008 (or 2005), you can do it too, with the few hundred lines of code below.
This sample WebBrowser features:
- Go Forward/Back
- adding and editing of favorites
- full screen view
- multiple web pages open
- address bar editing.
Start VS 2008 (or 2005). Choose File->New->Project->Visual Basic->Smart Device Project->Ok.
(You can also run this same sample as a standard VB Windows Form application to see it running on your PC. File->New->Project->Visual Basic->Windows->Windows Forms Application. You can actually have 2 projects in one solution: one for the SmartPhone, one for your PC, both sharing the same code: PhoneBrowser.vb. Then you can right click on the desired project and Set As Startup Project. Be careful of having 2 copies of the code: One copy actually references the Compact .Net Framework, and is in a different project type).
In the wizard that shows, choose Target Platform: Windows Mobile 5.0 Smartphone SDK, and Templates: Device Application
In Solution Explorer, Delete Form1, then add a new Class called "PhoneBrowser.vb"
Paste the code below.
In Project Properties, choose Application->Startup Object: PhoneBrowser
Hit F5 to build and run the program. A dialog comes up: choose either smart phone emulator. The first time, it takes a few seconds to deploy the .Net Framework 3.5.
Notes: use Tools->Device Emulation Manager to hook up the emulator to your network, so it can browse web sites. Right click on the emulator you chose and choose "Cradle" to attach the emulator electronically to your PC (like putting the phone into a cradle that's attached via cable). Otherwise you'll get "Your Internet connection is not configured properly. Please verify your settings in Data Connections"
Install Microsoft ActiveSync 4.5, run it, and choose File->Connection Settings->Connect to sync the emulator to the PC. This is not required, but will allow you to have your emulator connect to the web while it's cradled.
You can change the Output File folder where the application is stored: Project ->Properties->Devices->Output File Folder. It defaults to %CSIDL_PROGRAM_FILES%\SmartDeviceProject1
The sample doesn't show History: if you figure that out, let me know. Otherwise, I may just create a SQL Server CE database and store the links in there….
If you're using VS 2005, you'll get several VB compile errors that you can fix due to new features in VB.Net 2008
- Change due to Type Inference:
- Old: Dim NewWindow = New PhoneBrowser
- New: Dim NewWindow As New PhoneBrowser
- Change For loops to declare vars
- Old: For i = 1 To oBrowserForms.Count
- New: For i As Integer = 1 To oBrowserForms.Count
- Relaxed Delegates in 2008 means the method signature doesn't have to exactly match. To fix this, change the event handler method parameters to match.
- Old: ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs
- New: ByVal o As MyMenuItem, ByVal e As System.Windows.Forms.KeyEventArgs
- Now that the method signatures match, you'll have to cast some of the Objects to things like "MyMenuItem" or "MyListViewItem" :
- Old: Select Case o.Text
- New: Select Case CType(o, MyMenuItem).Text
- The sample uses Linq in a few places: just replace with the commented code below if Linq is not available (as in VS 2005)
The F1,F2 buttons on your keyboard map to the left and right soft keys of the phone.
To deploy on a real SmartPhone, connect via ActiveSync and choose Project->Properties->Devices->Target Device: Windows Mobile 5.0 Smartphone Device, then hit F5. You'll get some confirmation dialogs on your phone.
You can use Linq on your SmartPhone in VS 2008: if you get an error creating a simple query, Project->Properties: add a reference to c:\Program Files\Microsoft.Net\SDK\CompactFramework\V3.5\WindowsCE\System.Core.dll, and import System.Core and System.Xml
You may have to unlock your phone: https://blogs.conchango.com/stuartpreston/archive/2005/11/10/2376.aspx
