Windows Programming必须了解的naming-convention，下面解释每个前缀/缩略词的含义，如果含义的解释一行放不下的，就把解释放在一个引用框里
Prefix
Meaning
CS
Class style option
ps
eg: psText; a pointer to the character string,
DC
device context, The device context is really just a data structure maintained internally by GDI. A device context is associated with a particular display device, such as a video display or a printer. For a video display, a device context is usually associated with a particular window on the display.
rc
eg: rcPaint; a structure of type RECT, the RECT structure defines a rectangle with four fields named left , top , right , and bottom
MM
eg: MM_TEXT;
Windows has a variety of "mapping modes" that govern how the logical coordinates specified in GDI drawing functions are translated to the physical pixel coordinates of the display. The mapping mode is defined in the device context.
DT
Options related to DrawText function
SW
show window option
CW
Create window option
DT
Draw text option
IDI
ID number for an icon
IDC
ID number for a cursor
MB
Message box options
SND
Sound option
WM
Window message
SND
sound option
WS
Window style
UINT
unsigned int
PSTR
a pointer to a nonwide character string, that is, a char *
WPARAM/LPARAM
The origin of these names requires a bit of history. When Windows was a 16-bit system, thethird parameter to WndProc was defined as a WORD, which
was a 16-bit unsigned short integer, and the fourthparameter was defined as a LONG, which was a 32-bit signed long integer. That's the reason for the "W"
and "L"prefixes on the word "PARAM." In the 32-bit versions of Windows, however, WPARAM is defined as a UINT andLPARAM is defined as a LONG (which is still the C long data type), so both parameters to the window procedureare 32-bit values. This may be a little confusing because the WORD data type is still defined as a 16-bit unsignedshort integer in Windows 98, so the "W" prefix to "PARAM" creates somewhat of a misnomer.
WINAPI/CALLBACK
Both these identifiers are defined as __stdcall , which refers to a special calling
sequence for function calls that occur between Windows itself and your application.
MSG
Message structure
WNDCLASS
Window class structure
PAINTSTRUCT
Paint structure
RECT
Rectangle structure
HINSTANCE
Handle to an "instance"—the program itself
HWND
Handle to a window
HDC
Handle to a device context. A device context refers to a physical output device (such as a video display) and its device driver.
sz, eg: szCmdLine
string terminated by zero
h, eg: hPrevInstance
h stands for "handle"
i, eg: iCmdShow
i stands for integer
ui, eg: uiParam
ui stands for unsigned integer
c
char or WCHAR or TCHAR
by
BYTE (unsigned char)
n
short
i
int
x , y
int used as x-coordinate or y-coordinate
cx , cy
int used as x or y length; c stands for "count"
b or f
BOOL (int); f stands for "flag"
w
WORD (unsigned short)
l
LONG (long)
dw
DWORD (unsigned long)
fn
function
s
string
sz
string terminated by 0 character
h
handle
p
pointer
lpfn
long pointer to a function, Recall that in the Win32 API there is no distinction between long pointers and near pointers. This is a remnant of 16-bit Windows.
cb
stands for "count of bytes" and is often used for a variable that denotes a byte size
hbr
handle to a brush
lpsz
long pointer to a string terminated with a zero
np
near pointer, also a remnant of 16-bit windows
lpcwstr
long poiner to const wide character string (const wchar_t *)
