Surprisingly, going out, does not support 3G network connectivity, rather than using GPRS / EDGE wireless connection. To see in the third quarter of 2010, when it will be black, blue and green, orange, pink, purple, red, silver, white or yellow.

LG Electronics, the market value of recognition and singers together, the two have been launched LG slider phone GB280. As a phone, handheld device, including a 176 × 220 pixel resolution, 200 megapixel digital camera, FM radio, media player, Bluetooth stereo, Internet, e-mail support for the browser screen. Dolby Mobile and GSM / EDGE connectivity.

In addition to hardware specifications, equipment, also with a brand of wallpaper Lady Gaga, and several of his songs as a dance in the dark, and bad paparazzi romance and songs can be converted into ringtones, if you wish.

The phone will be launched in Brazil in 499 real understanding as 2.82 U.S. dollars.

A common problem is, there are many platform. On the open-source and a variety of platforms, we must say that they are still developing at this time is not yet widespread. In this article, we will give our attention to Windows Mobile platform. Microsoft launched the 90th end to the first platform for embedded devices. In 2002, based on Windows CE. Network appears. Pocket PC, and then based on Windows CE-3. 0 platform and the release of more people. In wireless communications technology development, integration of mobile phones and personal computers. Therefore, the Pocket PC 2002 Phone Edition support the same GSM, GPRS, Bluetooth and Wi-Fi access to SA standards. Meanwhile, another device is the development of the concept is very similar to the above, but close to call, and then personal computers.

The device was named for smart phones in 2002. And smart phones and Pocket PC handheld computer’s fundamental difference is that it has a touch screen, and only the smart phone’s buttons. They also have different applications, and supports a variety of standards and technologies. Windows Mobile platform, in most smart phones, communications equipment and small personal devices. Windows CE and Windows Embedded platforms are widely used in various industrial equipment. At present, our Windows Mobile 5 and Windows Mobile 6 and Windows Mobile 7 will be released on behalf of the near future. Windows Mobile-based Pocket PC-based modern equipment, there are about 500 to 600 MHz processor and 64-128 MB of RAM is not only for these devices.

Few model development tools Windows Mobile Applications: MFC of the Win32 API’s. NET Compact Framework,. Microsoft provides all the tools the joint development of PDA, handheld computers and smart phone applications, the required development. The following are the different types of code on the selection of some tips. The use of native code to achieve burst performance, work directly with the hardware, and to minimize system resource requirements. Graphical user interface development using managed code-oriented applications, the main requirement is the development and market deployment. Managed code is also very good work with the Web service is simple. The use of the server code, the work of different devices through a single code base, but also the stability of any channel of communication between a device exists.

The following is a Pocket PC, Pocket PC and Smartphone development tools currently comments. Embedded Visual C + + 4. 0 Microsoft eMbedded Visual C + + 4. 0 development environment designed to create a Windows CE device applications. Network 4. 2 operating system, and (with Service Pack 3 Update Rollup for PDA and smart phone) for Windows Mobile 2003 Second Edition platform. Integrated development environment in Visual C + + 4. 0 is to create a good mobile and embedded devices running Windows CE native code. Network 4. 2 operating system. It allows developers to only real-time diagnosis of an unhandled exception, the additional and the natural process of purification to extend the debugging process, and the interaction with the simulator. Visual Studio,. NET and functions of the SPD Social Democratic Party (smart device programming) and the Visual Studio integrated development environment features. NET 2003 (for 2005,2008) can build applications using Microsoft’s possibilities.

NET Compact Framework platform. Thus, developers can create mobile data with the online and offline learning phase deals with the distribution system to operate. Expanded library. NET Compact Framework provides a platform for application development faster than traditional development tools. Visual Studio,. NET to create for the Pocket PC 2002 device applications (with the appropriate SDK) in the Pocket PC 2003,2005 and Smartphone 2003,2005, application for the development of desktop applications using the same tool. Library. NET Compact Framework is the installation of Visual Studio. Teachers. This library is designed for devices with limited resources. Developers can also use the new language C # and Visual Basic. Mobile and Embedded Devices NET applications. They are adept at using the Web Services and ADO work. Teachers. Control element of the ASP. Net mobile controls extend the capacity and SDP.

NET Compact Framework platform. Dan the opportunity to availability. NET Compact Framework and Visual Studio,. NET to serve mobile network, due to a variety of data transmission using the ASP application development for mobile devices. Teachers. This method allows to create a Visual Studio in the mobile network. NET support, to provide automated data on different devices show: mobile phones, smart phones, PDAs, Pocket PC. Used to create by simply dragging the control elements in the form of mobile Internet applications, integrated development environment. Of the ASP. NET does not provide customer premises equipment components. In adapting to specific logic format in the server browser. The information generated in the wireless markup language (WML), HTML and compressed HTML format (cHTML, etc.).

Microsoft SQL Server, Microsoft SQL Server Compact Edition (SQL Server CE) for rapid development and application, and further with the company due to the use of mobile devices, the possibility of working data, compact the database management system. SQL Server CE is a tool to facilitate with the SQL syntax and application models support the use and API interface, with SQL Server-compatible mobile applications development. The SQL Server CE provides the basic functions of a relational database, including query optimization controllers, used to support, and business types of heterogeneous data sets – with a claim on system resources. The convergence of remote access to data and to provide replication from the SQL Server database, and information and synchronized with the server the possibility to work independently and reliable transmission of information.

A good SQL Server CE and mobile devices and wireless network systems. SQL Server CE database management system development and integration. NET Compact Framework using Visual Studio. Teachers. It simplifies the application development work with mobile devices and the construction of the database. From the SQL Server CE data management to provide a new common language runtime environment to develop application code can help self-regulation, with no permanent connection phase, information on employment opportunities. Microsoft. Net SqlClient’s work provides the API to serve. NET Framework y of the NET Compact Framework. For the SqlClient common Windows and Microsoft SQL Server system to use and SqlServerCe database, Microsoft SQL Server Compact Edition compact framework. SqlClient namespace is in two versions. Therefore, we can share: to use. NET Compact Framework for SqlClient from the device to the desktop access to SQL Server.使用.

NET Compact Framework’s SqlServerCe get a condensed version of SQL Server directly on the device. Equipment and a database similar to the work desk. To access the SQL Desktop SQL Server to use the system TCP / IP protocol, so in this case is not possible to SQL Server Compact Edition installed on the device. All of these models are implemented on the desktop. Therefore, its application experience, we can better develop Windows Mobile program. Use Win32 API to quickly get the code structure is compact, you can also use the driver development and system components of it. MFC extension application, API, and design and interface development functions. And use the Compact Framework, our disposal, a sound interface, automatic garbage collection, for XML support and other options.

Also has a further cut version – micro-architecture, and its SDK fewer features. For the MS after the reorganization of Visual Studio SDK setup and new features to install on these platforms. Demand also includes software development and test equipment and computers between the non-physical connection Emularor. For Windows Mobile-based devices have ARM processors, the unit can also use other compiler: predecessor AVR32, ARM, Inc. (the RealView), GNUARM, IAR Systems. 2. Building Windows Mobile application for Windows Mobile devices with Microsoft’s Visual Studio. Net Visual Studio development environment, while the development of Compact Framework applications that will use the graphical interface, large database, file and encryption tools, USB, Bluetooth and wireless network connections and telephones. All of this provides the SDK, as well as libraries and archives the departure of Platform Builder. 2. A user interface as a team of excellent designers and SDK exists, can easily develop mobile applications graphical user interface, as well as desktop applications.

The only difference is in the desktop and Windows Mobile graphics component group. There are between the Smartphone and Pocket PC version of the Pocket PC as an integral part of the difference between the touch screen, there is no smart phones. Thus, smart phone interface more complex. People should take into account the developing countries, the two platform software. Here, we should also mention the built-in Pocket PC software does not start in the smart phone platform, while the opposite is possible, until the time – When you call a special function of smart phones. It is natural that many of the graphical components and the most primitive features of the SDK is based on Windows Mobile separate in order to reduce the size of the SDK in terms of equipment. Only the most essential elements still exist.

However, the productivity and the amount of memory included in SDK is increasing the number of functions is growing. Therefore, the contractual framework between them a difference. 0 and 2. 0 is great. Version 1. 0 is very limited. Generally speaking, with the horse graphical user interface development? Ompact do? # It is similar to the common in the C # Win32 application development. It also can be developed using a graphical interface of the 3D engine arrangements. They like Gapi (Game API), OpenGL ES is the (embedded systems), OpenVG (and vector graphics), and other items. Of course, the more labor-intensive process in the context of writing is very important, because the relatively low productivity of mobile devices, the best code. 2. 2 files, so far, mobile devices communicate number of options. 802 access to them through high-speed wireless network. 11 a standard WiFi connection.

They also use infrared, Bluetooth and USB host / client-side functionality. Although less and less use of IrDA protocols, standards and gradually Bluetooth, WiFi, EDGE’s, GSM and exit are also frequently used USB interface. The API provided by Microsoft as a company: ActiveSync provides synchronization services for API, file filters, such as the Bluetooth API provides a wireless mobile devices and peripheral devices feature processing. Connection Manager API is used to connect process automation, network connection management. Devices are using Connection Manager to establish a connection, and to report the alleged connection (such as the internet). Object Exchange (OBEX) API with an agreement to provide an efficient, compact binary processing equipment suitable for only a limited possibility. Remote API (RAPI) provides the equipment and remote method call management features.

These features are available: registry access, file, database, and various configurations of the device from the desktop. The most important option is the remote procedure call, you simply call the method “CeRapiInvoke ()” on the desktop, referred to in the equipment in the name of the DLL and the DLL function name, and then simply call this method. Pocket Outlook Object Model API provides the functions of Pocket Outlook Object’s work. Providing an interface synchronization and access objects: task, calendar, contacts. Telephony API (TAPI), including: assisted telephone extends the API API API, SIM Card Manager API Short Message Service (SMS) API of the telephone service provider (TSP) API of the Wireless Application Protocol (WAP) of the API. Mobile devices also have the opportunity to serial (USB) of the. Few there are many devices on the COM port.

Under normal circumstances, the first is to retain 3-5 for IrDA, Bluetooth, serial port and so on. Other ports available to the user. Some products are USB host function, in other words, the USB On – The – Go’s (OTG) devices, can operate as both USB host and USB client. So we must have the necessary (and device drivers for hardware and software). A device driver is a driver, which is an application layer between the host controller and the middle tier. These factors for the ‘stream interface driver and control functions: xxx_init XXX_Open XXX_Close XXX_Write XXX_Read XXX_IOControl here, “XXX” is a’ be changed to “prefix (for example, ‘in COM’, ‘DSK’s'). This is registered, the prefix registered in the system drivers. more about the device driver interface details can be obtained from MSDN. At the same time developers can use the API, such as does not affect the media: the device configuration file API and Application Management API API API main screen games Index of HTML Control API API API API Shell’s TV MIDI recording vibrations identify the API control API. 2. 3 of the P / Invoke interoperability and as the Compact Framework is included in the basic functions and methods, we are fully The framework features such as XML serialization interoperability think about security encryption services, people, people.

In fact, platform invoke visit. for this purpose – the next orbit – our function and the system namespace attribute. run. InteropServices and DllImport attribute description is from a non-managed code calls a function. However, these methods function is limited. category, Mariscal has PtrToStructure, GetComInterfaceForObject, copy () and read () function, but, for example, does not exist GetDelegateForFunctionPointer role () it. Therefore, it can not only marshal the delegate. This feature is only available GetFunctionPointerForDelegate. If we pass a pointer to a function from managed code, you must let your FunctionPointer, and only in transmission to a non-managed code calls came back from there. In addition, we are unable to pass certain objects, because the Compact Framework can not count sizeof () a number of objects.

Therefore, we often want to send the data only Blitable types and these types of array (integer, byte, character , but not boolean), and send and receive IntPtr classes and structures. Of course, it was explained that the desire to improve performance. Therefore, recommendations on the organization and “GCHandle classes” to store the process of the main types of memory objects, such Memory ‘visible’ non-managed code, of course, the performance of the P / invoke an application for the C # in C + + DLL nearly two times to three times more than the method call with the C + +, DLL. However, the equipment, the performance of growth, as can be the use of this appeal. 2.4 Microsoft Visual Studio debugging allows the debugging, as well as desktop applications on Windows Mobile applications. We simulator, device simulation program managers, and other features, such as breakpoints, threads, timers, panels, etc.,

But, to use the machine and managed to debug the same time is impossible. Therefore, it is possible to initiate or C + + or management. For example, both “attached to the process.” there is unity in terms of equipment (or side Simulator) process may be nature. ActiveSync needs, equipment and systems to facilitate communication with the SDK installation. an emulator can also be connected to the computer via ActiveSync. we have almost complete Windows Mobile device simulation. The following is smart phones and Pocket PC (or Palm PC Phone Edition) simulator. However, only Windows Mobile devices can be connected to a computer, the time now. Therefore, in the two devices, while debugging, for example, interact in some way, it is very difficult. Of course, only the said that we have developed to debug the application, but not in the application and system services. for debugging, as we have Platform Builder to create (in the Platform Builder is the latest version of Visual Studio included) system to complete the construction. We have also can create our own Visual Studio SDK and Windows CE platforms.

A simulator can also simulate the GSM network connection and GPS support. This makes testing and development, rather than a physical device in their hands a wide range of applications. and the International Development Association Debugging should be mentioned that version 5.1 has the capacity to implement through the compilation of this interactive debugging using their plug-in is installed on the device. With the emergence of the choice of SDK, such as ‘implemented’ in Visual Studio. now, ” the implementation of the theme of “Project context menu In addition, the” Building “or” clean “, to” cleanse. “In selecting this theme the current configuration of the DLL or EXE built to send to the device. also appear in the new column configuration management is not only” to make any configuration options “available, and” implementation. “deployment. NET project is not only a uniform, but also for future generations, in its (addicted). 3. Implementation and deployment of applications for Windows Mobile development is the creation of the assembly and installation package. To do this concept is not the case then? Abinet (. cab) and Windows Mobile.

It is a common document, but it is also an installation package (MSI package one). they met through the cabin Wizard (cabwiz. exe) Microsoft VisualStudio (or command line). This tool can create a “processor dependency. “Cab. WinCEApplicationManager Constitutional Affairs Bureau and began transmission equipment, allows the user to install the application to appear in the device’s instructions. It can also create MSI installation projects, including the adoption of Visual Studio CAB file.-Building program, which the user the computer, and then transfer? AB installation of the equipment and continue the installation process. Uninstall Manager no special equipment side. you have additional INI configuration file CAB file. This INI file contains the management as the path to the installation process, the shortcut The name to create the smallest of the operating system to install applications and set up a special syntax to write. You can also include your own DLL file in the CAB file extension installation options. This DLL containing words such as “Installer_AfterInstall” feature, “Installer_BeforeInstall”, ” Installer_AfterUnInstall “,” Installer_BeforeUnInstall “, the code for these functions is a device-side implementation of the installation or removal process at some point.

In the development of CAB installation files can be connected to different resources, the construction units, the information added to the registry. They were designated as “Project Output. That is why there is no need to create the CAB file to restart the thing, “lists all the items and files and installation. 4. Safety of Windows Mobile 5 and Windows Mobile 6-based Windows Mobile models of equipment for receiving, sending and analyzing potential important information from security applications should be protected. In order to protect the unknown device has been disabled Starting the application, access to API, some restrictions, and to prohibit some changes to the registration. units can be marked as trusted and untrusted system uses this information to prevent unauthorized application startup, and restrict their access to the system.

You can also access via the RAPI (Remote API) system can be restricted through ActiveSync. safety certificate, the right to security for executable files (EXE, DLL), and CAB file unit. to protect against threats and the fans can choose the risk of protection devices: a strict password protection. PIN code protection. information equipment, in order to prevent corruption and repression of access to it (the doctors 6). information equipment to eliminate corruption and memory cards, in order to to prevent access to it (Western 6). warehouses, and Advanced Encryption Standard SSL encryption (Western 6). the proper use of the certificate. the device via Bluetooth detection, can protect (6 WM smart phones). 2 application-layer system startup (1 and 2 a level of access). there is no macro support, so that viruses can do great damage. to start the application is based on permissions. Windows Mobile devices using such models: ordinary privileges of privileged access for a wider range of obstacles. You can access any API, written to the register of protected areas, and take advantage of the system. most of the applications are a normal pattern. they do not have access to API and trust and have full control system. The application can not be started, if it is “locked” state.

This is means that it is not entered into the appropriate user certificate or prohibit appropriate alarm system to start. simulation status and cab files. with the normal state can begin an executable unit of the DLL, but then will work properly. However, units can not be executable privileges Start the normal state of the hard disk.
