n  UINT  Unsigned value (size dependent on operating system)  nLength  
w  WORD  16-bit unsigned value  wPos  
l  LONG  32-bit signed integer  lOffset  
dw  DWORD  32-bit unsigned integer  dwRange  
p  *  Pointer  pDoc  
lp  FAR*  Far pointer  lpDoc  
lpsz  LPSTR  32-bit pointer to character string  lpszName

b or f—used as a prefix for booleans (f stands for flag).
c—used as a prefix to chars.1
n—used as a prefix to shorts.
h—used as a prefix for a handle. Handles in Win32 are numbers used to identify resources or
windows. They are not pointers or pointers to pointers. Think of them as ID numbers.
l—used as a prefix to a long.
w—used as a prefix to a word.
dw—used as a prefix to a double word.
s—used as a prefix to a string.
sz—used as a prefix to a null-terminated string.2
p—used as a prefix to a pointer.
lp—used as a prefix to a long pointer (this is the same as a pointer in Win32 and is a relic
from Win16).
fn—used as a prefix to function parameters.


m_—all member variables are preceded with an m_.
On—all message handlers function should be preceded with On (e.g., OnSize). Note
however, that not all functions that begin with On are true Win32 message handlers. For
example OnInitialUpdate is not a Win32 message handler, and there is no corresponding
WM_INITIALUPDATE Windows message.
