Registry files windows ce

In previous versions, Windows CE could be configured for all kernel-mode operation, or for mixed-mode operation using both kernel mode and user mode. As shown in Figure 2 , some components have both a user-mode and a kernel-mode incarnation. This deployment helps minimize the cost of calling across the privilege boundary, at the expense of a larger operating system image.

The new kernel brings a completely new memory architecture that eliminates the previous limits on available processes and address space size. Previous kernels supported a maximum of 32 processes, each of which occupied its own process slot.

This is a theoretical maximum, based on a limit on the storage of kernel handles. The practical maximum is lower because other types of kernel objects occupy space in the kernel handle table. Prior to CE 6. In addition to having a larger address space, the structure of process address spaces is different. This change makes the CE 6. No doubt you're wondering what impact the new memory architecture will have on existing software.

Generally speaking, most changes are limited to device drivers. While the size of the process address space is much larger, well-behaved applications shouldn't notice, since memory is allocated using the same allocation APIs, and data is still stored using bit virtual memory pointers. The new memory architecture does make some things easier, particularly for applications that needed to allocate very large blocks of memory-greater than 10MB, for example-such as might be needed to hold a high-resolution image read in from a digital camera sensor.

Previously the need for large data blocks had to be satisfied by allocating with the shared memory allocation functions MapViewOfFile, for example. Starting with CE 6. Aside from the increase in size of the process address space, the other change introduced with this memory architecture is the truly private process address space. In the now defunct slotted address scheme, the currently running process is mapped into slot zero. This was done by fixing up all pointers to reference memory in the range of zero to 32MB.

By calling a function like MapPtrProcess, the currently running process can take a pointer from another process and access that memory directly in the process slot in the range 32MBMB for slot 1, 64MBMB for slot 2, and so forth. With the implementation of a private process address space, no application process can look into the address space of any other application process.

Instead, you will need to use the standard Win32 shared memory APIs to enable two processes to read and write to the same memory. One reason that this new architecture is likely to have the biggest impact on device drivers is that existing Windows CE device drivers often use functions like MapPtrProcess to read or write directly in an application's address space.

This is accomplished by linking to the appropriate set of kernel libraries k. In some cases, it might be necessary for a device driver to run in user mode instead of in kernel mode.

For example, there might be a driver for which you don't want to grant full kernel mode privileges. Such a driver can be run in CE 6. Now let's take a look at some of new features that are available with CE 6. Some are developer tool enhancements, while others are new features that you can include in custom embedded devices that you create. Many stories told by science fiction authors describe machines that behave like humans. And yet, stories are seldom written to extol the glory of machines that mimic other machines.

Isn't there something miraculous about a desktop system being able to simulate the behavior of a mobile phone? Such impersonation is actually nothing new. In fact, it is almost as old as computers themselves. Today, of course, there's the Microsoft Virtual PC, where emulation becomes virtualization.

Windows CE has seen three generations of emulators. It was a good first start, but left much to be desired. The second generation emerged as a custom embedded platform using hardware virtualization, running the same low-level instructions as a real device. It was a very capable emulator, but had a drawback for developers who were focused on deploying to non-x86 processors since it was built using the I86 instruction set.

A third-generation emulator, which ships with CE 6. This emulator ships with the CE 6. While the x86 instruction set dominates on the desktop, it has not made the same inroads in the embedded world.

The benefit of emulation at the machine instruction set level is binary compatibility. Instead of building the x86 executable files for the emulator and a second set of ARM executables for actual devices, you can create a single set of binaries and run them both.

In addition to being more convenient, it also enables a higher degree of testing confidence because you test everywhere with the same executables without worrying about errors in your setup scripts, or compiler or linker bugs. To enable machine-to-machine communication, CE 6. Another key component provided with CE 6. This component provides the low-level interface for connecting an application layer to the mobile phone hardware.

Previously, to build a mobile phone on Windows CE, you had to develop your own interface layer. This is not an easy thing to do, but something that a few stalwart pioneers have done. Among the other supporting elements in CE 6. You should note that the browsers provided with CE 6. To enable the creation of such wireless data terminals, there is rich support for SMS messaging.

This is important because the mobile phone network uses SMS to send notifications for services like voice mail, fax, and e-mail. 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. Hello, I m trying to import a dll file from smart phone device directly. I have a dll file ready with me. Is there a way to directly convert it into a smartphone compatible dll n use it there in smartphone application?

Also u have mentioned abt 3 ways in 2nd post.. Wednesday, July 1, PM. Tobey 0. Your terminology is confusing. What do you mean by "import"? What about "from smart phone device directly"? They must be recompiled from the source. You take the tool indicated from the location indicated and copy it to the device, where you run it with the name and path to the DLL containing the COM object on the command line.

I did manage to find the regsvrce and registered it but now I do have an additional error message Consider using PView to detect and remove it and now Wednesday, August 5, PM. Mohamed 0. I followed you instructions i downloaded the regsvrce. Monday, November 16, AM. Thanks in advance, PC i have the same problem. Wednesday, March 3, AM. That is, it doesn't require that type of registration.

Managed DLLs may need to be added to the global cache of managed code components, but they would never be registered using regsvr on Windows CE.

Friday, March 5, PM. Update: If you are looking to use IPv6, you will need to use the attribute "ipaddr6" rather than "ipaddr". The value will obviously need to be 20 bytes, rather than the 4 bytes used by IPv4. Hey guy, How to insert an IPV6 address hosts record into the wince registry? Does Wince support it? Appreciate for your kindly reply. I've never had to configure IPv6 on these devices.
