Windows CE Programming

Unfortunately, there is no in depth information about the Pocket or Mobile Internet Explorer (PIE) comaptibility. So I can only give some suggestions. But I hope this informations will help you getting started and don’t run into trouble.First, although M$ states, that PIE is compatible to Internet Explorer 4.1, 5.0, 5.5 or 6.0, depending on the OS level you run on a windows ce based device, this is only a general statement:

Pocket Internet Explorer has been updated to support the following:

HTML 4.01
Extensible HTML (XHTML)
Cascading style sheets
Microsoft Jscript® version 5.5
Enhanced scripting and Document Object Model support
Wireless Markup Language (WML) 2.0 (XHTML + WML 1.x)
Internet Protocol version 6 (IPv6) in IPv4/IPv6 mixed-mode environments
New extensible imaging library

From TechEd powerpoint

HTML 3.2 Compliant
JavaScript 1.1 compliant
XML Object Model
SSL
Active X support (no download!)
=============================
HTML 3.2-based object model
   Not the IE4 OM
Core script support:
   Scripting against FORM elements
   Scripting against the XML OM<
Not supported:
   Dynamic frameset creation
   Dynamic script generation
   Window.open

If you try some more special functions of the desktop IE versions, you will find the limits very fast. In example, the OnKey() event is not supported in any of the actual CE OS versions (<=6). XML Dataislands support is very limitted.

I have been asked, how one can see, if a device has been clean booted. Here is an answer.

First, there is a registry key you can check:

[HKEY_CURRENT_USER\Performance]
"Last Boot Type"=dword:00000002

after a coldboot this value is 0. For warmboots the value is 2.

and another one

[HKEY_LOCAL_MACHINE\Comm]
"BootCount"=dword:00000005

The BootCount value starts with 1 at a cleanboot and counts with every reboot. This device had 1 clean boot and 4 warm boots.

These registry keys are easy to find with free tools like ssnap and WinMerge.

Another way to check for a clean boot is to look for a custom file or a custom registry entry in \Windows. With a cleanboot all contents is reset to the factory default (except for \Flash File Store (persistent storage) or external memory cards). If you created a file in \Windows or a value in the registry, these are gone after a cleanboot.

I finished a toolset to free the function keys on windows mobile devices. That means a tool set that will give you back the function keys. Instead of F3 launching the phone app, you can free the F3 key and use it in your app.
