Description Videos Description Windows CE panel PCs provide a more affordable alternative to the Windows desktop panel PCs, yet still having enough performance and features to make professional user interfaces in a more compact size.

Apps such as Excel Mobile formerly Pocket Excel are not part of this kit. The older Handheld PC version of Pocket Word and several other older apps are included as samples, however.

Windows Mobile is best described as a subset of platforms based on a Windows CE underpinning. Each platform uses different components of Windows CE, plus supplemental features and apps suited for their respective devices.

The rules for manufacturing a Pocket PC device are stricter than those for producing a custom Windows CE-based platform. The defining characteristics of the Pocket PC are the touchscreen as the primary human interface device and its extremely portable size. CE v3. A successor to CE v3. The SmartPhone platform is a feature-rich OS and interface for cellular phone handsets.

SmartPhone offers productivity features to business users, such as email, and multimedia abilities for consumers. The SmartPhone interface relies heavily on joystick navigation and PhonePad input. Devices running SmartPhone do not include a touchscreen interface. SmartPhone devices generally resemble other cellular handset form factors, whereas most Phone Edition devices use a PDA form factor with a larger display. HandeldPC 2. Microsoft Wiki Explore.

Windows Embedded Compact. This 32 MB "box" is not as much a problem for the Windows CE programmer as it is a challenge to be overcome. To understand how this seeming large memory space is constraining, you must understand the operation of the VirtualAlloc API.

VirtualAlloc is the most fundamental memory allocation call in any Microsoft Win32 operating system. It allocates memory at the page level; the page being the smallest unit of memory that can be allocated or freed by the CPU.

The page size of a Windows CE. The 4 KB page size is the most widely used. The VirtualAlloc call allocates memory in two steps. First, a region of the virtual memory space is reserved. This reservation does not consume any RAM; it simply prevents a portion of the virtual address space from being used for other reasons.

After the memory space is reserved, portions or the entire region can be committed , which maps actual physical memory into the reserved region. The VirtualAlloc function is used for both reserving memory space and committing memory. The prototype for the VirtualAlloc function is shown below. The first parameter to VirtualAlloc is the virtual address of the region of memory to allocate.

The lpAddress parameter is used to identify the previously reserved memory block when you use VirtualAlloc to commit a block of memory previously reserved. The second parameter is dwSize , the size of the region to allocate or reserve. Because this parameter is specified in bytes, not pages, the system rounds the requested size up to the next page boundary.

The flAllocationType parameter specifies the type of allocation. Combining the reserve and commit flags uses less code, and is quicker and simpler. The problem is illustrated with the following code fragment. This code fragment seems harmless. It allocates blocks of memory each 1 page in size. The problem is how Win32 operating systems reserve regions of memory. When an area of virtual memory space is reserved on any Win32 operating system, including Windows CE. NET, it aligns the reserved region on a 64kilobyte boundary.

Thus, the fragment above attempts to reserve regions each aligned on a 64 KB boundary. The problem with Windows CE applications is that they must be located in the confines of a 32 MB virtual memory space.

This space has only 64 KB boundaries in the entire application memory space, and some of those are needed for the regions for the application code, local heap, stack, and for each DLL loaded by the application. Typically, the code fragment above will fail after approximately calls to VirtualAlloc. The solution to the above problem is to first reserve a region large enough for the total allocation, and then commit the RAM as needed as shown below. The key to avoiding this problem is knowing about it.

NET application is how to allocate huge blocks of memory. If an application needs a block of 8, 16, or 32 megabytes of RAM for a specific need, how can it allocate this memory when the entire address space of the application is limited to 32 MB? The answer is to apply a fix that was first used in earlier versions of Windows CE. NET for video drivers. It works out that if Windows CE. Instead, the block is reserved in the Large Memory Area that is positioned in the global memory space just below the 2 GB system reserved space.

When the memory space has been reserved, the application can commit specific pages within the reserved space with calls to VirtualAlloc. This allows huge memory blocks to be available to the application, or driver, even though it lives within the constraints of the 32 MB box.

The code below shows a simple allocation of a 64 MB block, and then commits one page of the reserved area.
