I want my webform to create a file on the users machine. How can I do this?
I tried this but it doesn't work...

Dim strFileName As String = "C:\Temp\MyFile.ABC"
Dim sw As New StreamWriter(strFileName)
sw.WriteLine(lblStartRun.Text)
sw.Close()
Response.Redirect(strFileName)

The ABC file extension is associated with a custom application on the users
local machine.

The error is "This page cannot be displayed..."

Thanks,
Robert
 
Try putting a try catch around and see what your error is..........

The problem is possible that that file path is not part of the web site and
will not be served by IIS
Try a path under the web directory eg c:\Inetpub\wwwroot\MyWeb\MyFiles\
or
write the file stream directly out to the browser without the overhead of
saving to disk first.
Set the file type ( doc, pdf , txt etc) in the header first.

I suspect you have a permissions problem. Perhaps the ASPNET user account
does not have write privilages to the temp folder you've specified.
One way to avoid such issues is to output the file directly to the user
without ever saving it to the server's hard drive.
Some code like this should do it:

Response.Clear();
Response.AddHeader("Content-Disposition","attachment;filename=myfile.abc");
Response.WriteFile("myfile.abc");

C:\Temp\MyFile.ABC is not a URL. What do you expect the user's browser to do
with this string?
