Opening Files

[danarashad]

Is there a way I could use coldfusion so users could open up a file in an external program. Then have make changes and save it back to the server.

First part: easy. Use CFCONTENT and the MIME type.

Second part: hard to impossible. The downloaded file is a copy of the original, and because of security considerations the application can NOT save it back to the Web server directly. They would have to save locally, then use some sort of upload tool. If you're in an Intranet, it may be possible if you give users access to the document share. Externally, though, no way without an upload step.

There's a good reason why document collaboration systems are so expensive ;^)

This worked great for me, with a little modifying of course.

Works for text files. What about spreadsheets, documents, etc.?

Yes I am actually opening a style sheet. All you have to do is, change the javascript to add a file extension.
<cfscript>
variables.validFile = 1;
if (NOT reFindNoCase('.css$|.htm$|.html$|.cfm$|.cfml$', URL.file))
{
variables.validFile = 0;
}
</cfscript>
Or if you want to target one file like I do. change this javascript. to match what file you want.
<cfscript>
if (NOT structKeyExists(form, 'fileExt')) form.fileExt = "style.css";
</cfscript>

So long as your file is ASCII and can be edited in a textarea. This doesn't work for binary format files.
