This sample project is created by the GroupDocs showcase team to demonstrate key benefits of an ASP.NET PDF viewer built using the commercial library – GroupDocs.Viewer for .NET. The viewer allows you to display PDF documents across all standard web-browsers (IE8+, Chrome, Mozilla Firefox, Safari 5+, Opera, etc.) without having to install any software or plugins on end-user machines. Another core feature – is the ability to display PDFs in a read-only mode, so that end users can’t download, print or copy original PDF files while viewing them in a browser. Please note that GroupDocs.Viewer for .NET is a paid library. In order to setup and run this project, you will need to download the GroupDocs.Viewer for .NET library from the GroupDocs website. For more details on the sample ASP.NET PDF viewer and to download the library, please read this article: > http://groupdocs.com/blog/asp-net-pdf-viewer-built-based-on-the-groupdocs-viewer-for-net-library

AlphaCentauri is a completely free office application, with various utilities resembling those distributed commercially on Windows. Functionalities are still quite limited compared to the commercial products, but more features will be added soon. Please note that update v1.1.0 has full featured programs, however you will see a watermark with "trial version" details. This is due to some features were used through Nevron's very useful and awesome libraries. Unfortunately, these libraries and dev tools are also very expensive. This should not interfere with working comfortably and saving clean docs. This is just a release version until I get my head around building those trialed features from scratch. If watermarks turn out annoying, one can always download the v.1.0.3 with basic features and UI.
