HOOK截获中文输入后如何把取得的文字替换后再返回给原来的输入框?

Question

已经用HOOK取得输入的内容,,现在如何替换为我想要输出的字符串，如何将它发送到目标编辑器。是用SendMessage吗?? 看有人VB是这么写的,VC要怎样写呢,,我没转成.  Const   WM_IME_CHAR   =   &H286   
  Const   WM_IME_COMPOSITION   =   &H10F   
    
  Dim   str   As   String   
  str   =   "你好吗^_^"   
  For   i   =   1   To   Len(str)   
  PostMessage   hwnd,   WM_IME_COMPOSITION,   0,   &H800   
  SendMessage   hwnd,   WM_IME_CHAR,   Asc(Mid(str,   i,   1)),   ByVal   1&   
  Next 不明白VC怎搞,,高手指点一下。截获中文输入的贴子

Answer 1

CString str = _T("你好吗^_^");
PostMessage(hwnd, WM_IME_COMPOSITION, 0, 0x0800);
SendMessage(hwnd, WM_IME_CHAR, str[i], 1);

Answer 2

CString str = _T("你好吗^_^"); 
for(int i=1;i<=GetLen(str);i++)
{
PostMessage(hwnd, WM_IME_COMPOSITION, 0, 0x0800); 
SendMessage(hwnd, WM_IME_CHAR, str[i], 1);
}

Answer 3

会死循环的重复输入啊char*   str="bbbd";
int len = _tcslen(str);
for(int i=1;i<=len;i++) 
{ 
   PostMessage(pmsg->hwnd, WM_IME_COMPOSITION, 0, 0x0800); 
   SendMessage(pmsg->hwnd, WM_IME_CHAR, str[i], 1); 
}
完整的代码如下case WM_IME_COMPOSITION:
//MessageBox(NULL, "ImmGetContext3", "ImmGetContext3", MB_OK);
//m_hEditWnd = pmsg->hwnd;
//if   (m_hEditWnd   ==   pmsg->hwnd)
{
                HIMC hIMC;
                HWND hWnd=pmsg->hwnd;
                DWORD dwSize;
                //char ch;
                
                if(pmsg->lParam & GCS_RESULTSTR)
                {
                    //先获取当前正在输入的窗口的输入法句柄
                    hIMC = ImmGetContext(hWnd);
                    if (!hIMC)
                    {
                        MessageBox(NULL, "ImmGetContext", "ImmGetContext", MB_OK);
                    }                    // 先将ImmGetCompositionString的获取长度设为0来获取字符串大小.
                    dwSize = ImmGetCompositionString(hIMC, GCS_RESULTSTR, NULL, 0);                    // 缓冲区大小要加上字符串的NULL结束符大小,
                    //   考虑到UNICODE
                    dwSize += sizeof(WCHAR);                    memset(lpstr, 0, 20);                    // 再调用一次.ImmGetCompositionString获取字符串
                    ImmGetCompositionString(hIMC, GCS_RESULTSTR, lpstr, dwSize);
//char*   buf="bbbd";   
//SendMessage(pmsg->hwnd,WM_SETTEXT,0,(long)buf);
//ImmGetCompositionString(hIMC, CS_NOMOVECARET, "end", 3);
//SendMessage(hWnd,WM_SETTEXT,null,(long)buf); char*   str="bbbd";
int len = _tcslen(str);
for(int i=1;i<=len;i++) 
{ 
PostMessage(pmsg->hwnd, WM_IME_COMPOSITION, 0, 0x0800); 
SendMessage(pmsg->hwnd, WM_IME_CHAR, str[i], 1); 
}                    //现在lpstr里面即是输入的汉字了。你可以处理lpstr,当然也可以保存为文件...
                    //MessageBox(NULL, lpstr, lpstr, MB_OK); 
//SaveLog(lpstr); 
FILE* f1;
f1=fopen("c:\\report_cn.txt","a+");
//char ch1;
//ch1=(char)(pmsg->wParam);
fwrite(lpstr,_tcslen(lpstr),1,f1);
fclose(f1);
                    ImmReleaseContext(hWnd, hIMC);
                }
            }
            break;

已经可以了,这样就对了
char*   str="bbbd";
int len = _tcslen(str);
for(int i=1;i<=len;i++) 
{ 
//PostMessage(pmsg->hwnd, WM_IME_COMPOSITION, 0, 0x0800); 
SendMessage(pmsg->hwnd, WM_IME_CHAR, str[i], 1); 
}
