Folks,

My application has streaming media with a download option.  The download button on the page is meant to open the file download dialog on the browser so you can save the media file locally.  I've wired my download link to the following code in the event:

            System.IO.FileInfo file = new System.IO.FileInfo("C:\\pathtomyfiles\\myfile.mp3");

            Response.Clear(); // clear the current output content from the buffer
            Response.AppendHeader("Content-Disposition", "attachment; filename=" + file.Name);
            Response.AppendHeader("Content-Length", file.Length.ToString());
            Response.ContentType = "application/octet-stream";
            Response.WriteFile(file.FullName);
            Response.End();

Adding the "Content-Disposition" header should make the file dialog pop up, but nothing happens.  Does DNN mess with the response headers?  Is there a more DNN-friendly way of making a file download link on a page?

Thanks for your help.

This is great, thanks.  I'd like to use LinkClick, but I've run into a little problem.

Early on, I found the standard file upload in DNN didn't provide a decent user experience for large file uploads.  I implemented Brettle NeatUpload, which gives me a progress bar, a cancel button and a more AJAXy feel.

But now I have a file full of media on the server that is not hooked in with the standard DNN file manager.  Are there APIs I can call on upload that can install my directory and files into the file manager and give me a FileID for the uploaded file?  Then I'll just store the FileID in my table, and I can use it in LinkClick.

Thanks!

PS: I will likely turn to Amazon S3 to store these files, eventually.  They're big.  Does the DNN file manager integrate easily with S3?

Thanks so much for your help.

I'm trying to figure out the right methods to call in FileSystemUtils and how to do it.  I'm guessing its something like the following, but this isn't working:

                FolderInfo fo = FileSystemUtils.GetFolder(PortalSettings.PortalId, "AudioFiles/");
                string result = FileSystemUtils.AddFile(Server.MapPath("~") + "\\Portals\\0\\AudioFiles\\" + file.FileName, PortalSettings.PortalId, true, fo);
 

At this point in the code, the audio file is already in the correct directory.  I'm just trying to get the DNN tables set up correctly.  The FolderInfo comes back correctly, but I've tried several ways of calling AddFile, and none of them are working.  Because it doesn't return a FileID, I'm not even sure this is the right method, but I can't find any that do.  What's the right method to call?
