Windows ce textout

And so CE 6. Before computers became mobile, there was little interest in figuring out the computer's location. Once delivered to its air-conditioned vault, a mainframe computer never needed to figure out where it was.

With today's pocket-size systems and onboard automobile computers, the subject of location is suddenly much more interesting. A major theme of the past few years has been finding ways to improve security of all computer systems.

And the CE 6. Before discussing improvements that have been made with CE 6. The centerpiece of Windows CE security is provided by the ability for a Windows CE-powered device to maintain tight control over which applications and DLLs are allowed to load and run. A common method for identifying authorized modules is through the use of digital certificates. Device security can be set up in a variety of different configurations.

For example, in one configuration any unknown modules-those without valid certificates-can be denied any system access. Alternatively, this mechanism can be turned off so that all modules have complete access to all system services. Another core security feature is the Cryptographic API, which allows applications to encrypt and decrypt blocks of data using a variety of encryption algorithms. And to enable secure connections with server systems, Windows CE provides support for a variety of authentication mechanisms, including the Windows NT LAN Manager protocol and the more robust Kerberos authentication protocol.

So what are the new security features with CE 6. As I discussed earlier in this article, there is strict separation of user-mode code from kernel-mode code. The perimeter security of a system can be vastly improved by supporting a secure loader.

A secure loader ensures that only trusted code gets to run on a system. In Windows CE 5. The trust decisions of the loader are certificate-based-this means that all code that runs on the system has to be signed.

The secure loader, if enabled, inspects the code signature and if the signature is signed by a trusted certificate then that code is allowed to run. If not, the module load fails. The OEM has control over what certificates are trusted and thus has control over the code that gets to run on the system. When a platform is configured with a feature that may compromise the security of the device, a security warning is issued.

Details of the potential compromise are provided, to help platform developers address the potential problems early in the platform development process. A final feature that was added to CE 6. This feature ensures that downloaded operating system NK. BIN images contain valid digital signatures before allowing the OS images to be installed and run on a system.

Visual Studio is, of course, the premier development tool for both client and Web development; now this same tool is available to support Windows CE. Some Platform Builder terms have changed to better fit into the Visual Studio paradigm. A Windows CE 5. The command to create a new Windows CE platform is similar in the two versions. For Windows CE 5. For CE 6. The project type is named "Platform Builder. As in the earlier version, the first step in defining a new platform is the selection of one or more Board Support Packages BSPs.

After that, the wizard prompts for a design template, which serves as a platform's initial configuration. Some of the Windows CE 5. The OS Design is added to a solution. After the wizard finishes, the newly created solution file is opened. Changes are also made to the Target menu. If you are new to Visual Studio, here are two tips to help get you started: the Solutions Explorer window plays a key role; if it is not open, summon it with View Solution Explorer.

Many configuration details are available by drilling into the contents of this window. Context or popup menus also play a key role in Visual Studio; summon these menus by selecting and clicking the right mouse button. For example, you can open an OS configuration window by selecting an OS Design solution from the Solution Explorer window and selecting the Properties menu item.

The most constrained resource in the world of software development is people time. And because better tools make for more productive people, the investment in development tools never ends. Now that the Windows CE Platform Builder-the centerpiece of embedded development-has been integrated into Visual Studio , the Platform Builder team will be able to focus more efforts on adding cool new tools instead of on maintaining the IDE, since Visual Studio has its own dedicated development team. You can already get a taste of the cool future tools that will come out of this group with two new capabilities being introduced with CE 6.

One is a graphical registry file editor, which makes it easier to edit and also add new registry keys and registry values into. A second cool tool is the runtime image viewer for peeking inside nk. This tool even allows you to compare two different nk. And finally, there is shared source. While technically not a tool, the phenomenon of open source that benefits Windows CE developers is something I'm very excited about. An important aspect of configuring Windows CE components involves creating settings for the system registry.

Previously, registry. Visual Studio provides a new registry file editor, as shown in Figure 8 , which is a lot more pleasant to use. When necessary, you can still edit the plain-text version of the registry file by clicking on the Source button at the bottom of the registry editing window. But the default editing mode resembles the familiar registry editing tools used by developers. Another nice development feature is the runtime image viewer.

By convention, a Windows CE image is written to the nk. In the past, it was difficult to know exactly what was in a given nk. And it was just about impossible to compare the contents of one nk. The image viewer provides help for these kinds of problems. Taking a cue from the open source movement, Microsoft began by making available a significant portion of the source code for Windows CE to anyone willing to download the Evaluation edition of the Windows CE Platform Builder.

Developers who build applications to run on Windows CE have gotten tangible benefits from other open source projects. NET Compact Framework. Win- dows CE 2. Before we look at the details of the Win32 support in Windows CE, let's examine some of the existing device types to get a feel for possible Windows CE applications.

Figure A typical Handheld PC. They typically have a keyboard, infrared port, serial port, and microphone. The standard software on these devices includes: Pocket Word, Pocket Excel, Internet Explorer, Outlook Express, and other scaled-down Microsoft productivity applications.

A Palm-size PC. And I have yet been able to get them to run correctly. But I think there is a way. I'm just not finding it. Hope someone can help. Cheers, Francis. January 21st, , AM 2. No Way on WinCE to set hooks , open process etc.
