// Coding Documentation
//
// [Hungarian Prefixes]
//	C			Class Object: Declares a class type or defines an object
//				of a class type. An object is an instance of a class.
//				eg:	class CMyObject
//	I			Interface that an object support.  It is called an interface
//				because it has a pure virtual function in it, so no instance
//				of this class can exist (ie, it must be inherited)
//				eg:	class IUnknown
//					class CDiscovery : public IUnknown
//	m_			Member variable of an object (eg: DWORD m_dwFlags)
//	s_			Static variable to a class (eg: static int s_cRefCount)
//
//	p			Generic Pointer (eg: CData * pData)
//	rg			Array with a known range (eg: CData rgData[100])
//	a			Dynamic array. Same as a pointer but pointing
//				to more than one element (eg: CData * aData)
//	sz			String terminated by a null-terminator (eg: char szName[20])
//	asz			Dynamic string
//	psz			Same as sz, however psz may be NULL
//	st			Pascal string (first byte is the length of the string)
//	stz			Pascal string with a null-terminator
//
//	f			Flag, typically a BOOL but can be a single bit (eg: BOOL fIsValid)
//	b			byte
//	ch			character
//	i			Index (not integer)
//	c			Counter (may be 8 bits, 16 bits, 32 bits or more)
//	n			Generic integer
//	l			Long integer
//	w			WORD	(16 bits)
//	dw			DWORD	(32 bits)
//	ib			Offset	(index to a byte)
//	msk			Mask	(eg: #define mskStyle	0x00FF)
//	mskf		Mask for a single bit (eg: #define mskfIsDirty	0x0100)
//	gr			Group   (eg: char grszName[] = "Foo\0Bar\0")
//
// [Useful Combinations]
//	pv			Pointer to void (eg: void * pvData)
//	cb			Count of byte (eg: int cbData)
//	cch			Count of characters (eg: int cchName)
//	rgch		Array of characters (somewhat similar to sz but not necessarily null-terminated)
//	rgb			Array of bytes (very similar to rgch)
//	rgsz		Array of strings (eg: char * rgszNames[] = { "Foo", "Bar" })
//
//
// [Hungarian Suffixes]
//	Max			Maximum value (not inclusive)
//	Most		Maximum value (inclusive). Most=Max-1
//	Last		Last item in a list (same as Most)
//	First		First item in a list (inclusive)
//	Min			Minimum value (inclusive)
//	T			Temporary value (eg: char szNameT[20])
//	Nil			Invalid value (eg: #define iItemSelectedNil	-1)
//	Null		Zero/empty/initial value
//
// [Resource IDs]
//	ID_ICON				Icon Resource
//	ID_MENU				Menu Resource
//	ID_BITMAP			Bitmap Resource
//	ID_CURSOR			Cursor Resource
//	IDR_				Custom Resource
//	IDC_EDIT			Edit Control
//	IDC_IPEDIT			IP Edit Control
//	IDC_LIST			ListBox Control
//	IDC_IPLIST			IpListBox Controls
//	IDC_BUTTON			Button Control
//	IDC_RADIO			RadioButton Control
//	IDC_CHECK			CheckBox Control
//	IDC_COMBO			ComboBox Control
//	IDC_STATIC			Static Control
//	IDC_				Generic (or Custom) Control
//
//	IDD_				Dialog Resource
//	IDD_PROP_			Property Sheet Dialog
//	IDD_PAGE_			Page of a Property Sheet
//	IDD_WIZ_			Wizard Sheet Dialog
//	IDM_				Menu Command Id
//	IDS_				String Id (From StringTable)
//	IDS_ERR				Error message
//	IDS_STATUS			Status bar message

// [Callback Procedures]
//	WndProc				WindowProc
//	DlgProc				DialogProc
//	DlgProcWiz			Dialog Procedure of a Wizard page
//	DlgProcProp			Dialog Procedure of a Property page
//	DlgProcPage			Dialog Procedure of a generic page

// [File Extensions]	
//	.INL		Inline functions
//  .DLG        Dialog Templates
