Developing Applications

Applications for the Dolphin 7400/7450 hand held computer are developed for the Microsoft

Windows CE environment.

Microsoft Windows CE is a compact, highly efficient, scalable operating system created for embedded systems and products. Its modular design allows developers flexibility to customize it for a variety of small footprint and mobile 32-bit devices. Windows CE supports various hardware peripherals, devices and networking systems. These include keyboards, touch screens, serial ports, Ethernet connections, and storage devices, such as PC cards.

The Windows CE kernel is the central module of the operating system. It is the part of the operating system that loads first, and it remains in main memory. Because it stays in memory, it is important for the kernel to be as small as possible while still providing all the essential services required by other parts of the operating system and applications. Data synchronization also is not supported as the Dolphin 7400/7450 terminal is not designed for use as a single target.

The Dolphin 7400/7450 terminal can be easily programmed with Microsoft eMbedded Visual Tools (contains CE versions of Visual C++ and Visual Basic) or Java. Dolphin 7400/7450 supports Insignia Solutions Jeode Java Virtual Machine to run Java-based applications on the terminal.

Windows CE also runs SQL Server™ CE, the powerful yet compact relational database that extends enterprise data management. SQL Server CE has the familiar feel of SQL Server, with tools, application programming interfaces (APIs), and Transact-SQL syntax that minimize development time.

To get started with developing applications for your Dolphin 7400/7450 terminal, see the electronic help file that comes with the SDK.
