You need to realise that you can't save a file to the C: drive from within a web browser without user intervention because of security issues.

You will *always* get the dialog box up asking what you want to do with the file, 'Open it' or 'Save it'.

Can you imagine the havoc that could be caused if this could be circumvented. :w00t:

You can either use the URL method you have been using, in which case you get the dialog to Save or Open the file, or use the Web Service method as previously mentioned. Although, if you use this method you will need to write a windows app to enable you to write to the users local disk. Using ASP.NET will only allow you to render the file on the server then serve it back to the user in the browser whereupon you will get the 'Open/Save' dialog again. Back to square one.
