This is a very interesting solution. Is this something that could also work with WPF Windows? Has anyone published a solution for WPF?

Comment on Explicit Interface Implementations in C# by Tuzo

Interesting article. As of .NET 4 it looks like RegistryKey no longer hides the Dispose method.

Interface hiding also explains why the expansion of a using statement’s finally block expands to:

if (resource != null) ((IDisposable)resource).Dispose();

If the resource was not cast to an IDisposable then, if the interface was hidden (implemented explicitly), it would not be possible to call Dispose on the resource object without the cast.

That’s an amazing solution. I second your statement about being as elegant as it can get.

Works like a charm.

Thanks heaps for that.

Comment on Apple Lossless decoder with 24-bit support. by Jim Avera

FYI the copyright date printed when running the 9/5/2009 version (from http://craz.net/programs/itunes/files/alac_decoder-0.2.0.tgz) still shows as 2005. Since the version is not embedded in the software, it is hard to tell which version one is looking at except from the name of the .tgz archive file.

You might want to embed the version number (e.g. 0.2.0) and include it in the help message, so people can tell what version of a binary they are running.

Thanks for a great piece of software!

Hello David!
Thanks for the code above. It’s perfect for me.
In my code I have included two more things:
1. MdiParent
2. BringToFront
The only thing I have changed is the GetInstance method:
public static T GetInstance(Form owner, params object[] args) where T : Form
{
if (!mTypeFormLookup.ContainsKey(typeof(T)))
{
Form f = (Form)Activator.CreateInstance(typeof(T), args);
mTypeFormLookup.Add(typeof(T), f);
f.Owner = owner;
f.MdiParent = owner;
f.FormClosed += new FormClosedEventHandler(remover);
}
else
{
Form f;
mTypeFormLookup.TryGetValue(typeof(T),out f);
f.BringToFront();
}
return (T)mTypeFormLookup[typeof(T)];
}
