Hungarian Notation

• Basic Order:

[Prefix]-[BaseTag]-Name-[Suffix]

• [Prefix]:

m_
non-static class data members [ compound ]
s_
static data ( module/function scope ) [ compound ]
sm_
static class data members [ compound ]
g_
global variable [ compound ]

• [BaseTag]:

p
pointers [compound ]

pv
pointer to a void argument
pp
pointer to a pointer
ref
references [ compound ]
rg
array [ compound ]
c
count of items

h
HANDLE, abstract pointer
hr
HRESULT
b
BOOL / bool or other flag
bt
BYTE (unsigned char)
v
void
ch
char/TCHAR

s
short(16 bits)
i
int
l
long(32 bits)

w
WORD (unsigned short)
dw
DWORD (unsigned long)
u
any unsigned [ compound ]
ui
UINT
ul
ULONG
us
USHORT

f
float
d
double

sz
CHAR *, string (both null terminated and CString)
wsz
WCHAR*, Unicode string
tsz
TCHAR*, Flexible Unicode
bstr
BSTR/ bstr_t
var
VARIANT/variant_t
e
enum variable or parameter

vec
vector
mat
Matrix
lst
list

• [Suffix]:

_c
constant
_t
suffix for any type ( including enum’s)

• Remark.
-- Compound means the prefix or suffix is typically used in combination with additional notations. Combine prefixes in the order <reference/pointer><array><modifer><type>.
-- There is one notable case where Hungarian usually does not add to the readability of code and that is code doing mathematical computations. In this case, simple names such as x, y, z, i, j, k, etc. can be easier to read and are totally acceptable.

Member Function Names
We highly recommend using the following standard prefixes for member function names.
Function prefix
Type of function
F…
Query operations that return a bool
Get…
Gets a property.
Set… or Put…
Sets a property.
Create…
Dup…
Creates or duplicates a C++ object. Use “Duplicate” for a method that duplicates the object itself. Objects returned by these functions must be disposed with delete.
On…
After…
Protected notification methods usually overridden by clients. Where both On and After methods are provided, On is called prior to the event, and After is called after.
Draw…
Move…
Modifier operations (named with active verb phrases).
Swap
Swaps the contents of one object with the contents of another in a way guaranteed to succeed and not throw an exception.
