键盘钩...没有得到大写或大写字符

下面的功能是记录"0","z"和"1"确定...但它没有捕获"Z"(shift-z)...任何帮助将不胜感激...

__declspec(dllexport)
LRESULT CALLBACK HookProc (UINT nCode, WPARAM wParam, LPARAM lParam)
{
    if ((nCode == HC_ACTION) && (wParam == WM_KEYUP))
    {
        // This Struct gets infos on typed key
        KBDLLHOOKSTRUCT hookstruct = *((KBDLLHOOKSTRUCT*)lParam);

        // Bytes written counter for WriteFile()
        DWORD Counter;

        wchar_t Logger[1];

        switch (hookstruct.vkCode)
        {
        case 060: Logger[0] = L'0'; break;
        case 061: Logger[0] = L'1'; break;
        case 90: Logger[0] = L'z'; break;
        case 116: Logger[0] = L'Z'; break;
        }

        // Opening of a logfile. Creating it if it does not exists
        HANDLE  hFile = CreateFile(L"C:\\logfile.txt", GENERIC_WRITE,
            FILE_SHARE_READ, NULL,OPEN_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);

        // put the file pointer to the end
        SetFilePointer(hFile,NULL,NULL,FILE_END);

        // Write the hFile typed in logfile
        WriteFile(hFile,&Logger,sizeof(Logger),&Counter,NULL);

        //WriteFile(hFile,&hookstruct.vkCode,sizeof(hookstruct.vkCode),&Counter,NULL);
        // Close the file
        CloseHandle(hFile);
    }
}

键盘不发送字符.它发送密钥.无论您是键入z还是Z,您仍然按下相同的键,并且该键两次都具有相同的VK代码.

您还应该在按下或释放Shift键时收到通知.您可以使用这些通知将击键转换为字符.大写锁定状态也与此相关.您可能还会担心死锁.

您可以检查是否按下了Shift键.GetAsyncKeyState会告诉你钥匙的状态,现在,并GetKeyState会告诉你钥匙的状态,从消息队列中删除的最后一条消息的.

Z没有虚拟键码.尝试这样的事情:

            case 90:
                 if(GetKeyState(VK_LSHIFT|VK_RSHIFT)
                     Logger[0] = L'Z'; break;
                 else
                     Logger[0] = L'z'; break;
