016 EventDemo 5

小项目

● 拖拽控件

● 设置编辑框属性

● 程序逻辑

● 获取焦点的事件

void CEventDemoDlg::OnSetfocusEditText()
{
    // 获取焦点
    MessageBox(L"Hello");
}

● 启动以后会不停的弹 下消息框

● 解决办法多拖动一个按钮即可

初始化代码

    m_hEvent = CreateEvent(nullptr, TRUE,FALSE,nullptr);//设置位手动 设置无信号

实现代码

void CEventDemoDlg::OnSetfocusEditText()
{
    // 获取焦点
    //MessageBox(L"Hello");
    if(m_hThreadGetCount == INVALID_HANDLE_VALUE)
        m_hThreadGetCount = (HANDLE)_beginthreadex(nullptr, 0, ThreadGetCount, this, 0, nullptr);

    if (m_hIsURL == INVALID_HANDLE_VALUE)
        m_hIsURL = (HANDLE)_beginthreadex(nullptr, 0, ThreadGetCount, this, 0, nullptr);

    ResetEvent(m_hEvent);//Event设置位有信号状态
}
unsigned CEventDemoDlg::ThreadGetCount(void* lParam)
{
    CEventDemoDlg* pThis = (CEventDemoDlg*)lParam;
    WaitForSingleObject(pThis->m_hEvent, INFINITE);
    CString szEdit;
    //pThism_Edit.GetWindowText()
    int strLeng = pThis->GetDlgItemTextW(IDC_EDIT_TEXT, szEdit);
    pThis->SetDlgItemTextW(IDC_STATIC, (LPCTSTR)strLeng);
    return 0;
}
unsigned CEventDemoDlg::ThreadIsUrl(void* lParam)
{
    return 0;
}
