Shawn,
This issue is very strange. I tried your code, and posted my result on your blog.
However, using the exact same configuration (WinXP Pro, Framework 1.0) I get no
problem by following Russell's test. I even tried overwriting that file that you
created (sfddebug). The issue seems to be the parameter to ShowDialog. Converting your
code into the following does the trick.
HTH,
Jason Hagar
using System;
using System.IO;
using System.Windows.Forms;
public class MainModule : Form
{
[STAThread]
static void Main()
{
Application.Run(new MainModule());
}
public MainModule()
{
// Create a dummy file in the cwd.
if (!File.Exists("sfdbug.txt"))
{
using (StreamWriter sw = File.CreateText("sfdbug.txt"))
{
sw.WriteLine("Overwrite me!");
}
}
// Now to demonstrate the bug -- when prompted, choose to overwrite sfdbug.txt!
SaveFileDialog sfd = new SaveFileDialog();
sfd.Title = "Try to overwrite sfdbug.txt -- I dare you!";
sfd.InitialDirectory = Environment.CurrentDirectory;
sfd.DefaultExt = "txt";
sfd.Filter = "Text files (*.txt)|*.txt|All files (*.*)|*.*";
// Uncomment the following line, and all is ok.
// sfd.OverwritePrompt = false;
// Here's the bug: dr==Cancel, even when we answer 'yes' to the
// overwrite prompt!?
//DialogResult dr = sfd.ShowDialog();
MessageBox.Show(sfd.ShowDialog(this).ToString());
//MessageBox.Show("You pressed: "+dr.ToString());
// Here's the workaround: ignore the DialogResult, and simply look at
// the SFD's FileNames property (it'll be a zero-length array, if the
// user chose not to overwrite the existing file.
//MessageBox.Show(String.Format("And SFD returned {0} filenames",
sfd.FileNames.Length));
}
}

Umm... did you actually try to overwrite a file, Russel? What OS?
I'm now officially not the only person to repro this!
http://weblogs.asp.net/savanness/posts/10446.aspx
(Thanks Scott...)
I've repro'd this bug on three flavors of XP -- Home, Pro, and Tablet -- all of the
machines' shell settings in various degrees of messiness. I haven't yet tried to
repro on a perfectly clean, freshly formatted machine. Or on W2k3 Server, for that
matter.
The workaround (looking at SFD.FileNames.Length) is trivial -- my goal here is
hopefully someone from MS will investigate this, and raid the bug. One never knows
when these kinds of things may be symptoms of some larger bug...?
Cheers,
