You can't pass a cursor. You can pass an object or a string. Which you decide to se depends on the nature of tha caller. In most cases, an ADO recordset would be perfect for this. You can download the VFPCOM utility from the MS VFP site- it has methods to convert a cursor to and from a REcordSet. But depending on what you want to do, XML might be a better choise for this- I recommend you download Rick Strahl's wwXML class from www.west-wind.com. It has methods taht convert VFP cursors (and objects) to and from XML documents, which can be passed around as strings throug hte COM interface.
