Hello...
Lacking a few informations, I'll make a few guesses as to where you're
stuck.
By "Webform", I assume you're using ASP.NET.
Next, I assume you can retrieve your binary file from the database...
Then, when trying to send the file to the client, you have to specify
a few items in the Response... Something like
HttpContext.Current.Response.ContentType = "application/octet-stream"
'sending a file in binary format
Response.AddHeader("Content-Disposition", "attachment; filename=" &
filename) 'filename is quite explicit
HttpContext.Current.Response.BinaryWrite(bar) 'bar is the binary array
you load from your sql database
I hope useful to you...
