Saving textbox data as .txt file?

[Paul Evans]

Hi,

Can anyone help me?

I have two text boxes, one single-line and one multiline.
I wish to save the text within the multiline textbox as a txt file,
with a file name by the text in the single-line textbox.

Does that make sense?
If the single-line textbox is 'helpme', I wish to create a txt file of the
multiline textbox called helpme.txt

I have found cound so far as follows, but this only adds text from a textbox
to an existing file.

<%@ Import Namespace="System.IO" %>

<Script Runat="Server">

Sub Button_Click( s As Object, e As EventArgs )
Dim objStreamWriter As StreamWriter

objStreamWriter = File.CreateText( MapPath( "myFile.txt" ) )
objStreamWriter.WriteLine( txtInput.Text )
objStreamWriter.Close
End Sub

</Script>

Can anyone help please?

First, it is bad design practice to allow a user to submit data that
will be used in a filename path. This opens the door for attacks on your
system.

But, I'd imagine you'd want to change this line to the following:

objStreamWriter = File.CreateText( MapPath( SingleLineTextBox.Text &
".txt" ) )
That should work, but again that is extremely bad design practice.
