    .Net Native Interface Library for Delphi

    The best library to work with .Net Assemblies in Delphi.

    The .Net Native Interface Library (DotNetNativeInterface) is a native programming interface which provides a way for Delphi programming language to interact with applications and libraries written in any of the .Net languages (such as C#, VB.Net etc). Programmers can use DotNetNativeInterface native methods to access .Net 3rd party libraries or .Net Framework Libraries without the need for registry entries, COM registrations or changes to the .Net libraries. The following examples illustrate when you need to use DotNetNativeInterface native methods: 1. You want to access and use .Net Framework Class Library in your application. 2. You want to access and use 3rd party .Net Libraries in your application. Competitive Advantages: 1. Access to .Net Framework Class Library. 2. No COM registration of .Net Libraries is required when deployed. 3. Allows any programming language to consume .Net libraries as if they were native code.

    OXml

    The next generation XML library for Pascal (Delphi, FPC, Lazarus)

    OXml is the most versatile XML library in the Pascal world. Supported compilers: - Delphi (non-unicode): 5-2007 - Delphi (unicode) for Win32, Win64 and OSX: 2009+ - Delphi for ARC (iOS, Android): XE4+ - Lazarus for Win32, Win64, Linux, OSX: 1.0+ - corresponding C++Builder versions should be supported too (not tested though) Main benefits: - All on the target platform available single- and multi-byte codepages are automatically supported. - True unicode support on all platforms and compilers (also for Delphi 4-2007). - The XML parser is a standalone unit, making it possible to write different and user-defined XML interfaces. - Extremely fast thanks to clever buffering. Parsers included in OXml: - Basic standalone XML reader and writer. - DOM (W3C DOM Level 1.0 Specification). - Sequential DOM parser - SAX parser
