从 Win32 编辑框获取输入[C++]

Question

大家好，我一直在尝试从 Win32 文本编辑框中获取输入，如下所示：

    char IP_ADDR[200];
    char NICK[200];
    #define Print(msg) print_line(*hwnd, msg)
    #define Println() Print("\r\n")


        Print("Welcome to Basic Client 0.01 Alpha!");
        Println();
        Print("Please enter your IP address");
        Println();
        for (;; Sleep(500))
        {
            if (IsKeyDown(VK_RETURN))
            {
                GetDlgItemText(*hwnd, IDC_MAIN_EDIT2, IP_ADDR, sizeof(IP_ADDR));
                SetDlgItemText(*hwnd, IDC_MAIN_EDIT2, "");
                break;
            }
        }
        Print("Please enter a nickname");
        Println();

        for (;; Sleep(500))
        {
            if (IsKeyDown(VK_RETURN))
            {
                GetDlgItemText(*hwnd, IDC_MAIN_EDIT2, NICK, sizeof(NICK));
                SetDlgItemText(*hwnd, IDC_MAIN_EDIT2, "");
                break;
            }
        }

但这不会进入循环或停止它，直到按下键它才会继续运行如果它有助于我有运行功能，这是代码来自一个新线程，以便它可以在管理这里的窗口消息是代码：

Client * c = new Client;
.....
int Run(HWND *hwnd)
{
    MSG msg = { 0 };
    while (msg.message != WM_QUIT)
    {
        if (PeekMessage(&msg, 0, 0, 0, PM_REMOVE))
        {

            TranslateMessage(&msg);
            DispatchMessage(&msg);
            _beginthreadex(0, 0, ClientThread, (void*)hwnd, 0, 0);

        }


    }

    return 1;
}

unsigned int __stdcall ClientThread(void*data)
{

    HWND *hwnd = (HWND*)data;


    c->Run(hwnd);
    return 0;
}

这里是 IsKeyDown 函数：

bool Client::IsKeyDown(int vk)
{
    return ((GetAsyncKeyState(vk) & 0x1) != 0)? true:false;
}

哇，我的坏人，我把 beginThread 放在消息循环中，正如退休忍者指出的那样，这就是导致所有问题的原因。
