世界著名问题 2种语言 取词 返回值为何不同

[msfm]

vc]

typedef BOOL WINAPI (*TextOutANextHook_t)(HDC hdc, int nXStart, int nYStart, LPCSTR lpszString,int cbString);
TextOutANextHook_t TextOutANextHook = NULL;
typedef BOOL WINAPI (*TextOutWNextHook_t)(HDC hdc, int nXStart, int nYStart, LPCWSTR lpszString,int cbString);
TextOutWNextHook_t TextOutWNextHook = NULL;
typedef BOOL WINAPI (*ExtTextOutANextHook_t)(HDC hdc, int nXStart, int nYStart, UINT fuOptions, CONST RECT *lprc, LPCSTR

lpszString, UINT cbString, CONST INT *lpDx);
ExtTextOutANextHook_t ExtTextOutANextHook = NULL;
typedef BOOL WINAPI (*ExtTextOutWNextHook_t)(HDC hdc, int nXStart, int nYStart, UINT fuOptions, CONST RECT *lprc, LPCWSTR

lpszString, UINT cbString, CONST INT *lpDx);
ExtTextOutWNextHook_t ExtTextOutWNextHook = NULL;

static void IsInsidePointW(const HDC DC, int X, int Y, LPCWSTR Str, int Count)
{这里的X为什么与DELPHI中的XStart不同的值呢？
}


BOOL WINAPI TextOutWCallbackProc(HDC hdc, int nXStart, int nYStart, LPCWSTR lpszString, int cbString)
{
if (CurParams && CurParams->Active)
IsInsidePointW(hdc, nXStart, nYStart, lpszString, cbString);
这里的XnXStart什么与DELPHI中的XStart不同的值呢？
return TextOutWNextHook(hdc, nXStart, nYStart, lpszString, cbString);
}


BOOL WINAPI ExtTextOutWCallbackProc(HDC hdc, int nXStart, int nYStart, UINT fuOptions, CONST RECT *lprc, LPCWSTR lpszString,

UINT cbString, CONST INT *lpDx)
{
if (CurParams && CurParams->Active)
IsInsidePointW(hdc, nXStart, nYStart, lpszString, cbString);
return ExtTextOutWNextHook(hdc, nXStart, nYStart, fuOptions, lprc, lpszString, cbString, lpDx);
}

static void InstallTextOutHooks()
{
HookAPI("gdi32.dll", "TextOutW", (PROC)TextOutWCallbackProc, (PROC*)&TextOutWNextHook);
HookAPI("gdi32.dll", "ExtTextOutW", (PROC)ExtTextOutWCallbackProc, (PROC*)&ExtTextOutWNextHook);
}



[delphi]
function NewExtTextOutW(theDC: HDC; nXStart, nYStart: integer; toOptions:
Longint; rect: PRect;
Str: Pwidechar; Count: Longint; Dx: PInteger): BOOL; stdcall;
type
TExtTextOutW=function (theDC: HDC; nXStart, nYStart: integer; toOptions:Longint;
rect: PRect; Str: Pwidechar; Count: Longint; Dx: PInteger): BOOL; stdcall;

Hook[fExtTextOutW]:=THookClass.Create(Trap,@ExtTextOutW,@NewExtTextOutW);

nXStart 为何 返回值不同?

不是一家搞得。。。。。。。。。。。

Delphi进行了封装,JF

DELPHI对很多SDK API进行了封装

[WizardK]

不是SDK，是WIN API，类似于微软提供的PLATFORM SDK
