Hi, I couldn't find help doc for Build Action properties. In the drop down list, there are: None, Compile, Content and Embedded Resource, what are those mean and when to use which one? And how is this property related to property "Copy to output directory"? ------- If I have some files like xslt file, file based database(like access or sqlite) used by the application. I want them to be part of release. Must I copy them to project root folder? And must/can I include them as "resource" or just a file in project(I done by show all files in project and then use "Include in Project" cmd)? Can I "embed" any kind of resource? Thanks a lot! Ryan
