// History (Date/Author/Description):
// ----------------------------------
//
// 2005/07/13: Daniel Bowen
// - Namespace qualify the use of more ATL and WTL classes.
//
// 2004/08/26: Daniel Bowen
// - Break out checkbox image creation
// - Have CDynamicDialogImpl automatically call ConstructDialogResource
//   after the constructor, but before the dialog is created
//
// 2004/06/28: Daniel Bowen
// - Support hiding the description and/or last modified columns
//   in the "save modified items" dialog.
//
// 2004/04/29: Daniel Bowen
// - Original implementation
