如何利用HOOK，截获中文输入

[vcdll]

我截获WM_CHAR消息
可是最终是乱码

[papaya_stone]

我也想知道如何截获这个字符！

WM_IME_CHAR
The WM_IME_CHAR message is sent to an application when the IME gets a character of the conversion result. Unlike theWM_CHAR message, this message can include double-byte as well as single-byte character values.

// for double-byte characters:
chCharCode1 = (char) wParam & 0xff;
chCharCode2 = (char) wParam >> 8;
// for Unicode:
chCharCode1 = (WORD) wParam;
lKeyData = lParam;

Parameters
chCharCode1 and chCharCode2
(For double-byte character sets) Single- or double-byte character value. For a double-byte character, chCharCode1 contains the lead byte.
chCharCode1
(For Unicode) Unicode character value.
lKeyData
Repeat count, scan code, extended-key flag, context code, previous key-state flag, and transition-state flag, as shown following: Bit Meaning
0 - 15 Repeat count: Since the first byte and second byte is continuous, this is always 1.
16 - 23 Scan Code: Scan code for a complete FE character.
24 - 28 Not used.
29 Context code.
31 Conversion state.


Remarks
If the WM_IME_CHAR message includes a double-byte character and the application passes this message to DefWindowProc, the IME converts this message into two WM_CHAR messages, each containing one byte of the double-byte character.

QuickInfo
Windows NT: Requires version 4.0 or later.
Windows: Requires Windows 95 or later.
Windows CE: Unsupported.
Header: Declared in imm.h.

WM_IMECHAR可以截获到

[zhuwenzheng]

use WM_IMECHAR

是啊，没有必要用HOOK,在MSDN里输入IMM,有很多函数和消息的

这个消息有时无效，比如在word里面就没有这个消息。

如果要处理的不是你自己的PROCESS, HOOK一定要用. 你不能处理WORD的IME MESSAGE.
首先需要用setwindowshookex把你的代码投入到要处理的PROCESS中去,然后可以直接处理WM_CHAR, 如果你要处理IME输入过程本身, 才需要WM_IMECHAR.

现在的问题根本不是怎么做钩子，而是现在就没有这个消息。

钩消息没有太大的用处，因为很多输入法在输入汉字时并不是都能触发WM_IMECHAR消息，有些输入法通过直接向INPUTCONTEXT结构写入汉字来达到
输出汉字的。
你可以通过钩子将你的代码注入所有进程，枚举每个进程装载的DLL,在DLL名称是*.ime的dll里将ImeToAsciiEx修改，
函数原型入下：
UINT WINAPI ImeToAsciiEx (UINT uVKey,UINT uScanCode,CONST LPBYTE lpbKeyState,LPDWORD lpdwTransKey,UINT fuState,HIMC hIMC)
其返回值是输入的汉字数，指针lpdwTransKey指向汉字消息串，通过修改
ImeToAsciiEx，你可以截获输入法输出的汉字
