Mobile Matters: Windows Phone Navigation, Part 2: Advanced Recipes

Many Windows Mobile Pocket PC Phones and Windows Mobile Smartphones can be connected to a Windows PC via Bluetooth for use as a wireless dial-up modem. If your Windows Mobile device supports Bluetooth Dial-Up Networking, or Bluetooth DUN, and your Windows PC Bluetooth-enabled, you have everything you need.

In this tutorial, we'll show you how to use Windows Mobile Pocket PC Phones or Smartphones as a Bluetooth modem for Windows XP PCs.

I open sample project, build goes OK.
When i try to run it (or just deploy it) i get error "No such interface supported" and project does not strat.

It was working ok a day ago, i had to install VS 2008 since and this is my suspect No1.

Any ideas? Thank you.

Running on Windows 7.

Even if mobile dev is not my every day work, thanks to the .Net Compact Framework, it's still .Net programming.

Here is the scenario:

You come back home, you have a windows mobile phone wifi capable and you want to quickly get access to your phone pictures from your home network.
You just activate the Wifi, run my app and then browse to the provided link from any computer on the network.

I want to continue to build out the intranet site we've started in our previous articles. A standard item in every intranet is a staff/employee list. Most companies implementing Windows SharePoint Services (WSS) are large enough to have a database that contains all employees. We will use the aggregation features of SharePoint to include data from this database into our intranet.

Periodically I get a request for information on how to read and write binary data to a database running on Windows Mobile. If you search the Internet you can typically find examples that are available on Windows Desktops or allow you to read and write to a local file system. The problem is that it can take a bit of work to get this code to work on Windows Mobile accessing a database.

Ultimately you might be asking, why would I want to store and image in a database? Well in an environment where you synchronizing data between a local mobile database and a consolidated (central) database this can be extremely useful. Imagine if an insurance adjuster went to an accident scene, took a picture of a damaged car, loaded it into his Windows Mobile database and then replicated that image up to the Insurance headquarters for approval. All of this could be done in a very short period of time when using images in the database. Another good example might be a doctor who was waiting for a patient chart to become available. If you could store the image in a database this chart could be sent down to the doctor's device once it became available.

For this article I am not going to get into how to synchronize the images to and from a remote and central database as this is typically fairly straightforward when using a data synchronization technologies like MobiLink

A Cab file is the default setup format for Windows CE and Windows Mobile devices (similar to windows .msi files). You probably already have installed several application using .cab files, and are familiar with the concept. One point which is often unknown is that .cab files are processed by wceloader.exe, and it can only install one .cab file at a time. That means we cannot have nested .cab files. It doesn't mean we cannot have .cab files contained by another .cab, but the contained .cab files will not be installed during the installation of the container .cab. We should install it manually after the container .cab file installation has been completed.

There are two ways to create a cabinet (.Cab) file. The traditional one, and the friendly VS Smart Device Cab project which doesn't require additional coding, but which also relies on the traditional one at low-level.
