save file

Hi,
In my win application I use the following code to save the downloaded data into the necessary format

sw = File.CreateText(strPath & ".csv")

please not ethat .csv can be .xml instead

This works fine but what should I do in web (asp.net)?
I can not use the above line as it complains about the network path where the file should be installed.

If the best way is to get a dialog box to save as then how is it done please?
thanks

Something along the lines of...

(please not that this is in C# but you should be able to translate it easily)

Code:

---

private void cmdSelectOutputFile_Click(object sender, System.EventArgs e)
{
        SaveFileDialog sfd = new SaveFileDialog();
        sfd.OverwritePrompt = true;
        sfd.DefaultExt = "txt";
        sfd.Filter = "Text File (*.txt)|*.txt";
        sfd.ShowDialog();
        //public string...
        SavePath = sfd.FileName;
}
