MS Office Forum / General MS InfoPath Questions / August 2006Base64Binary form publish error
I get the following error when I try to publish a form to my SharePoint 2007 beta 2 server: "the selected field cannot be promoted becasuse its data type is not supported: base64Binary" This only happens when I try to use a filed that is a file attachment and try to publish the column to my SharePoint server. This IS a supported control for the Web browser...so what gives????? Web-supported control is entirely different from SharePoint supporting the field as a promoted column. Sharepoint promoted field columns have limited datatype support and base64 is not one of those. You can use the field in your form... just don't promote it to a SharePoint column.

As per the datatype, the file is stored as a base64 string. The extraction would be to select this string, then covert back to an actual file and save it. I've seen code that does this sort of thing... you might be able to track some down. If not, the better place to ask for code to convert a base64 string back into a file would be in the C#, VB.NET or ASP.NET newsgroups. Good luck.
