When building Windows services we often need a way to communicate with them. The natural way to communicate to service is to send signals to it. But this is very limited communication. Usually we need more powerful communication mechanisms with services. In this posting I will show you how to use service-hosted WCF web service to communicate with Windows service.
Excel with its file formats is not the only spreadsheet application that is widely used. There are also users on Linux and Macs and often they are using OpenOffice and other open-source office packages that use ODF instead of OpenXML. In this post I will show you how to read Open Document spreadsheet in C#.
I’m building web application for customer and there is requirement that users must be able to import data in different formats. Today we will support XLSX and ODF as import formats and some other formats are waiting. I wanted to be able to add new importers on the fly so I don’t have to deploy web application again when I add new importer or change some existing one. In this posting I will show you how to build generic importers support to your web application.
