Secrets of the Windows Mobile Home Screen API

One of my recent projects at Enterprise Mobile was creating a custom home screen (see above) for the new MotoQ9h and Blackjack II devices. The top row is the standard Windows Mobile “Icon Bar”. The second row has the clock, messaging center (SMS, Mail, Voicemail), and current profile.

At first glance, I assumed this would be a breeze. I have a powerful layout, key handling, and paint framework that I use in every project I work on, and thought that creating a home screen leveraging that would make it trivial. Sadly I was sorely mistaken. Read the rest of this entry »


VC Project Template for Smart Device CE Setup DLLs

It’s pretty annoying to have to create a CE Setup DLL cpp and def file every time I make a new CAB. So I finally got around to creating a VC Template to handle that for me. You can download it here.

Sadly, I did not create an installer for this template.

Installation instructions (adjust your installation directory accordingly):

  1. Unzip the contents onto your drive.
  2. Copy CESetupDLL.ico, CESetupDLL.vsdir, and CESetupDLL.vsz to C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\vcprojects\smartdevice
  3. Copy the Scripts and Templates folders into C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\VCWizards\SmartDeviceAppWiz\CESetupDLL
  4. Edit CESetupDLL.vsz and edit the ABSOLUTE_PATH value to whatever you supplied in Step 3.

And that should do it! You will now find the new project template in Visual Studio under the Smart Device folder in Visual C++.

Using HTC Diamond’s Accelerometer/Sensor SDK from Managed Code

When I first got my HTC Touch Diamond a while ago, one of the first things I tried to do was reverse engineer the Sensor API found in HTCSensorSDK.dll. However, anyone who has tried to reverse engineer DLL arguments knows how tedious and painful it can be to create a dummy DLL to intercept valid arguments, parse through assembly, and inspect random memory pointers. Luckily, I did discover a registry key: HKEY_LOCAL_MACHINE\Software\HTC\HTCSensor\GSensor\EventChanged which let me figure out what the general orientation of the device was; and that was good enough for what I was trying to do.

However Scott, from scottandmichelle.net, successfully reverse engineered the HTCSensorSDK.dll. This allows developers to use the g-sensor that is available on the device. Very impressive work on the part of Scott!

Anyhow, I spent a portion of today writing a managed wrapper for HTC’s Sensor API. The code includes a sample Teeter-esque type application which allows you to roll a ball around the screen. Read the rest of this entry »


Automating Build Versioning and Publishing of Smart Device Projects with Team Foundation Build

A few months ago I sent out an email describing the process of setting up the Team Foundation Build System to play nicely with Smart Device Projects. This mail included: setting up the build machine to work with Smart Device Projects, account permissions, publish location, versioning, and also a workaround to making Smart Device CAB projects buildable by TFS. I’m sure other developers have had to or will have to go through the same pains of figuring this out, so I decided to publish it a la blog. Read the rest of this entry »
