-Net60, a .NET Compact Framework Version 1.0, introduces .NET programming to the
-great family of Symbian S60 smartphones. Now it is possible to run a managed .NET
-application, written for Windows Mobile, on S60 smartphones. Unfortunately,
-however, the .NET Compact Framework 1.0 does not provide any form of database
-support. This is first supported in the .NET Compact Framework 2.0 together
-with the SQL Server Compact Edition. This SQL Server only runs on Windows
-Mobile <span class=GramE>devices which means</span> another database system is
-needed to provide database functionality to Symbian devices. Enter SQLite for
-S60.<o:p></o:p></span></p>
-
-<p class=MsoNormal><span lang=EN-US style='mso-ansi-language:EN-US'>SQLite is a
-popular open source, stand-alone database system that was written in C and is
-available for Windows, Windows Mobile, OS2 and <span class=GramE>Unix</span> operating
-systems. It is ACID compliant and supports the SQL-92 standard. The Symbian OS at
-present does not provide a database system, however in the future Symbian OS
-Version 9.4 will support a SQLite implementation. <o:p></o:p></span></p>

-href="http://developer.symbian.com/wiki/display/oe/P.I.P.S.+Home">http://developer.symbian.com/wiki/display/oe/P.I.P.S.+Home</a>
-) for the S60 and UIQ platforms. P.I.P.S. is the implementation of the POSIX
-Interface for Symbian OS that provides C Libraries like STDIO or STDLIB. With
-the Open C SDK it is possible to port the SQLite library written in ANSI C to
-Symbian OS. To do such a conversion of an existing ANSI C project knowledge of
-programming for Symbian OS is needed. A good description of the conversion of
-SQLite to S60 is the article on Dr.Dobbs (<a
-href="http://www.ddj.com/mobile/198702204?pgno=2">http://www.ddj.com/mobile/198702204?pgno=2</a>)

-the SQLite project. <o:p></o:p></span></p>

-<p class=MsoNormal><span lang=EN-US style='mso-ansi-language:EN-US'>Note, the

-SQLite source could be completely compiled, the file IO operations had to be
-rewritten. This part of SQLite is not platform independent and uses the native
-OS operations to open, read and write files.<span style='mso-spacerun:yes'>
-</span>The first step was to rewrite the file operations with the STDIO
-implementation.<span style='mso-spacerun:yes'> </span>For example the <b
-style='mso-bidi-font-weight:normal'>OpenDatabase</b> method was modified to use
-the <b style='mso-bidi-font-weight:normal'>fopen</b> method of POSIX. Unfortunately
-this did not result in the outcome that was expected. <span

-not run. After analyzing this, it seems to be that the ANSI C file IO methods
-cause the error. <span style='mso-spacerun:yes'> </span>The Symbian API is an
-object oriented programming interface, therefore to use the native file IO <span
-class=GramE>classes,</span> the SQLite source must be converted from .C files
-to .CPP files. Renaming the files was easy, but after renaming the source files
-over 500 compiler errors were output. Most of these were language differences
-between C and C++ and could be solved quickly. After resolving these problems,
-programming the OS routines with the Symbian file IO classes could begin.<o:p></o:p></span></p>
-
-<p class=MsoNormal><span lang=EN-US style='mso-ansi-language:EN-US'>For this
-part a new file was created and added to the SQLiteS60 project
-(os_symbian.cpp). This file includes all methods that SQLite expects for file
-IO. The conversion of the existing C files of the SQLite project to CPP files
-makes the SQLiteS60 project very different from the main source. As a result of
-this, the implementations for the other OS operations, i.e. for OS2, Windows and
-Mac, were deleted from this project. SQLite uses a structure to reference the
-correct OS operations and is implemented in every OS implementation. Due to this
-practice, only a compiler switch is needed to generate a run-able SQLite library
-for the specific operating system. As this structure is not used in the S60
-conversion project, it has also been removed from the code and the Symbian IO
-methods are directly connected to the OS methods in the file os.cpp.<o:p></o:p></span></p>

-<p class=MsoNormal><span lang=EN-US style='mso-ansi-language:EN-US'>With this
-conversion of SQLite, it is now possible to create .NET applications with database
-support for the great family of Symbian S60 smartphones. With the upcoming release
-of version 9.4 the Symbian OS provides an implementation of SQLite but this
-version is not released yet and only new devices will get this database
-support. With this conversion all S60 3<sup>rd</sup> Edition devices will be able
-to use SQLite. Together with the Red Five Labs Net60 implementation of the .NET
-Compact Framework it is possible to run .NET applications on Symbian OS. Together
-with the ADO.NET provider for this SQLite implementation these applications can
-use database functionality like any other application on a personal computer.<o:p></o:p></span></p>

-Visual Studio 2005 together with the Carbide.vs Plugin (http://www.forum.nokia.com/main/resources/tools_and_sdks/carbide/<span

-SDK are required to compile the project. With the Carbide plug in it is
-possible to develop native Symbian applications in the Visual Studio IDE and to
-debug on the S60 emulator. To convert a S60 project (f.e. a BLD or MMP file) to
-a Visual Studio project, the Import Wizard of the carbide plugin could be used.
-It is located under the File menu. The user only has to select the s60 project
-and to assign an S60 SDK (f.e. maintenance release or FP1/FP2). The rest of the
-transformation does the wizard. So it is easy to convert existing projects to
-use the carbide plugin.<o:p></o:p></span></p>
