Hi,

I have an ASP.Net app which displays data from a spreedsheet. This
spread sheet is located outside of the virtual directories.

I want to be able to give the user the option to download the
spreadsheet, without having to move it into the virtual directory.

Does anyone know how I can achive this?

Is there away I can grab the file and fire it to the users browser?

Many thanks in advance

Chris

You can use the HttpResonse.WriteFile method to write the file to the
reponse stream. Here is a simple example:

FileInfo myFileInfo=new FileInfo("MySpreedsheet.xls");
Response.WriteFile(myFileInfo.FullName,0,myFileInfo.Length);

Thanks Anders, I've tried that and it seems to write the actual
contents of the file to the Browser.

I am trying to give the user the option to download the file, so would
need it to pop up a Save, Open type dialogue.

TIA

Just provide a link to a page that uses HttpResponse.WrtieFile. You
should also add a "content-disposition" header with its value set to
"attachment; filename=myfile.xls" where myfile.xls is the actual name of
your Excel spreedsheet file to ensure that a file download dialog is
shown to the user.
The following code adds a "content-disposition" header:
Response.AddHeader("content-disposition",string.Format("attachment;
filename={0}",myFilename));
