While I am not sure of specific issues to do with Silverlight, in generating excel documents you could: - generate a CSV - there are plenty of free 3rd party .Net components for creating excel documents without reliance on other external things. This may overcome any dependency/security issues by writing a valid binary/xml file directly. - aspose have a decent excel component, but they are pricey. (Microway do a pretty good deal $$$) All the above 3 options would work with a server side solution too. While not recommended by microsoft, Excel Automation using a singleton pattern could be used, but there are a few issues that may arise (or may not) dependent on what you are trying to do. -- Les Hughes l...@datarev.com.au _______________________________________________ ozsilverlight mailing list ozsilverlight@ozsilverlight.com http://prdlxvm0001.codify.net/mailman/listinfo/ozsilverlight
