Use features of Windows Mobile devices to adjust your applications.

Q: Pocket PCAnd SmartphoneDifferent versions (for example
2002 , 2003 )?

A: Windows Mobile
Each new version of the software is built on a variety of existing development platforms available for developers, while maintaining a consistent core, so that the application can be oriented to a variety of devices. Currently, there are three common Windows
Mobile Software Version:

  • Windows Mobile 2002 software: the software that runs a device is sometimes called Pocket PC 2002 and smartphone
    2002. New developer features include mapi and Connection Manager.

  • Windows Mobile 2003 software: 2003 software version adds. NET Compact framework to a 2003-based device
    Rom. This allows developers to write managed code applications for devices based on Windows Mobile 2003. Other new features include Configuration Manager, Bluetooth programmability, and SMS
    Interception supported.

  • Windows Mobile 2003 second edition: Second Edition allows device manufacturers to use the main features of this version (for example
    Horizontal, square, and high-resolution screens of the Pocket PC and qvga of the smartphone
    Screen support) for innovation. Its name reflects the consistency of the Development Platform, which has not changed for this version. All APIs that support the new screen direction and resolution are always part of the platform.

Q: How can I identify different software versions?

A: both the Pocket PC and Smartphone have an about panel in settings. Settings can be set from the start
Menu.

Based on the code, you can use the getversionex function to query the maximum and minimum OS versions and the exact internal version number of the software.

Pocket PCDevelopment

Q: What tools can be used Pocket PC 2003Development?

A: To build a local C ++ application for Pocket PC 2003, you need Microsoft Embedded Visual C ++
4.0. Microsoft Embedded Visual C ++ 4.0 Service Pack 3 and Pocket PC 2003
Software development kit. You can downloadEmbedded
Visual c ++ Tool
AndPocket
VPC 2003 SDK
. The Windows Mobile 2003 second edition simulator package enables you
Test your application on the second edition device. Note that the Pocket PC 2003 SDK does not support Microsoft Embedded Visual
Basic development. To build a Pocket PC 2003 hosting code application, you needVisual Studio
. NET 2003
AndPocket
VPC 2003 SDK
.

To build a Pocket PC mobile Web application, you can useVisual
ASP. NET mobile control in Studio. NET 2003

Q: Pocket PC 2002The application can Pocket PC 2003
Does the device work?

A: Pocket PC 2002 applications with well-functioning documentation APIs can run on the Pocket PC 2003 device without recompilation.

Q: Why? Pocket PC 2003Not Supported EVBDevelopment?

A: On the Pocket PC 2003 device, we will continue to support the EVB runtime as an installable Ram component, such as the old EVB
The application can run on a new device, but it leaves Visual Basic. net, Visual C #. net, and Microsoft. NET.
The Compact framework provides a more powerful and robust development experience. New EVB development for Pocket PC 2003 devices will not be supported.

According to customer feedback, the Pocket PC 2003 device will include. NET Compact framework in the Rom .. NET Compact
The framework is a subset of the complete. NET Framework and is designed specifically for smart devices. It is a type
2002 a more comprehensive and language-independent application engine provided by the device that is specific to the EVB runtime.

Q: How EVBMigrate Visual Basic. net ?

A: It is not easy to migrate from EVB to Visual Basic. net, but the benefits of migration far exceed the cost:

  • Richer data types: EVB only has 16-byte variant; Visual Basic. net uses. NET Framework generic type systems.

  • Faster execution: EVB needs to be explained; Visual Basic. Net compiles JIT (Real-Time) into local code before execution

  • Improved error handling: EVB only supports "on error"; Visual Basic. Net supports structured exception handling

  • Supported structure: EVB is not supported; Visual Basic. Net supports namespaces, classes, and structures.

  • Object-oriented: EVB is procedural; Visual Basic. Net supports full OOP (Object-Oriented Programming)

  • First-class citizens: EVB always wants to catch up with MFC; Visual Basic. NET is the core. net

  • XML support for local machines: EVB is not supported; Visual Basic. Net supports XML and XML Web Services for local machines.

  • Improved data model: Ado. Net far exceeds adoce; it is still the best data model

  • Safer and more reliable execution: EVB is a scripting language, and Visual Basic. Net is a hosted code.

  • There are many more!

At the same time, there are a variety of resources (from porting experiments to technical articles) to help developers with this transition. An example is an overview of how to migrate from EVB to Visual Basic.
