SUMMARY

Unlike most Shell Extensions, Control Panel Property Page Extensions do not run in Windows Explorer's process and cannot be debugged by shutting down Windows Explorer and debugging it.

To debug a Control Panel Property Page Extension, the executable for the debug session should be set to:

   <windows dir>/rundll32.exe

And, the arguments should be:

   shell32.dll,Control_RunDLL <control panel your page is added to>.cpl

MORE INFORMATION

The technique described here is subject to change in future versions of Windows and is provided for debugging purposes only. If you want your application to launch control panel applications programmatically, you should use the control.exe program.
