//	class CAutoDeletePropPage
//
//	This object is the backbone for property page
//	that will *destroy* itself when no longer needed.
//	The purpose of this object is to maximize code reuse
//	among the various pages in the snapin wizards.
//
//	INHERITANCE TREE (so far)
//	CAutoDeletePropPage - Base object
//		CChooseMachinePropPage - Dialog to select a machine name
//			CFileMgmtGeneral - Dialog to select "File Services" (snapin\filemgmt\snapmgr.h)
//			CMyComputerGeneral - Dialog for the "My Computer" (snapin\mycomput\snapmgr.h)
//		CChoosePrototyperPropPage - Dialog to select prototyper demo (NYI)
//	
//	HISTORY
//	15-May-1997		t-danm		Creation. Split of CChooseMachinePropPage
//					to allow property pages to have more flexible dialog
//					templates.

//	This object is a stand-alone property page used to

//
//	The object CChooseMachinePropPage can have its dialog
//	template replaced to allow a new wizard without any new code.
//	The object can also be inherited, allowing easy extentionability.
//
//	RESTRICTIONS:
//	If the user wishes to provide its own dialog template, here
//	are the dialog IDs that must present:
//		IDC_CHOOSER_RADIO_LOCAL_MACHINE - Select local machine.
//		IDC_CHOOSER_RADIO_SPECIFIC_MACHINE - Select a specific machine.
//		IDC_CHOOSER_EDIT_MACHINE_NAME - Edit field to enter the machine name.
//	There are also optional IDs:
//		IDC_CHOOSER_BUTTON_BROWSE_MACHINENAMES - Browse to select a machine name.
//		IDC_CHOOSER_CHECK_OVERRIDE_MACHINE_NAME - Checkbox to allow the machine name to be overriden by command line.
