And seriously, thanks again for the pointers, everyone. I appreciate this kind of feedback more than you may realize, and I want this series to be as interactive as possible. I’m not a real/professional developer and am learning as I go as well. Thanks.
As you may recall, I tried to implement a semi-reasonable clone of the Notepad dialog that appears when you try to exit with a document with unsaved changes. I assumed that this dialog was something provided not by the system because I couldn’t find anything like it in Visual Studio. But as and jhoersch pointed out, this dialog wasn’t created specifically for Notepad. Instead, it’s a system-provided feature called a Task Dialog that debuted alongside Windows Vista as a replacement for an extension to the capabilities provided by the Message Box dialog.
