I think you want something along these lines... public class Singleton : Component { private Singleton m_instance = null; private Singleton(){} // constructor is private so it can't be created externally public static Instance() { if(!m_instance) m_instance = new Singleton; return m_instance; } } Your instance counting and dispose logic should still work. To use it, you dont create a new Singleton, but rather use Singleton s = Singleton.Instance();. -pete

Yeah, what he said :-D -pete

There's a much easier way to debug this problem that doesnt (normally) require anything to be done to your clients machine. Use the .MAP file generated by the compiler. Look in the .MAP file for the next lowest function offset from the FAULT entry offset in the Dr. Watson log file. That will show you what function the fault is happening in. If you didn't have the .MAP file enabled when you built what's running on your customer's machine, you can enable it now and build it as long as everything else is the same. -pete

All you should have to do is use ::MoveFileEx(OldFolderName, NewFolderName, 0). There's nothing built into MFC that I'm aware of to do this. This doesn't kill the contents of the folder. It would probably be safest to use absolute paths for each paramter. If something in the folder is in use, you can specify a flag for the 3rd param to wait until reboot. -pete

You could set up an XML file containing the picture information: Then have an XSL or client-side script that represents the static parts of the page and renders the HTML with the contents of the XML file that you upload. Hope that helps... -pete
