Hi, I'm using a bog standard OpenFileDialog with Mono 2.0 RC 1 (code below). When I run the app, everything is fine until I go to the directory which contains .spec files (these are plain text files used for packaging under Linux).. it then goes kabloom with the following throwback (from MD 1.9)
Unhandled Exception: System.ArgumentNullException: Argument cannot be
null.

The application was terminated by a signal: SIGHUP
Code which did the nasty....
8-->
private string createDialog()
{
OpenFileDialog filer = new OpenFileDialog();
filer.Filter = "spec files (*.spec)|*.spec";
filer.Title = "Select a spec file";
return ( filer.ShowDialog() == DialogResult.OK )
? filer.FileName : null;
}
private void button1Click(object sender, EventArgs e)
{
createDialog();
}
<--8
Nothing nasty, it just doesn't behave!
Any ideas?
TTFN
