VC编写任务栏右下角图标程序

任务栏右下角图标程序：在CMainFrame头文件中定义变量：  NOTIFYICONDATA  nid;在OnCreate函数中或者初始化函数中：nid.cbSize = sizeof(NOTIFYICONDATA);nid.hWnd = m_hWnd;nid.uID = IDI_SYSTEMTRAY; //图标的IDnid.uFlags = NIF_MESSAGE|NIF_ICON|NIF_TIP;nid.uCallbackMessage = WM_SYSTEMTRAY; //图标对应的消息的IDnid.hIcon = AfxGetApp()->LoadIcon(IDI_SYSTEMTRAY);wcscpy_s(nid.szTip,10, L"桌面锁");::Shell_NotifyIcon(NIM_ADD,&nid);用ON_MESSAGE将WM_SYSTEMTRAY与消息函数绑定：LRESULT CMainFrame::OnSystemTray(WPARAM wParam, LPARAM lParam){    if(wParam == IDI_SYSTEMTRAY)    {        switch(lParam)        {        case WM_LBUTTONDOWN:            {                break;            }        case WM_RBUTTONDOWN:            {                break;            }        case WM_LBUTTONDBLCLK:            {                break;            }        }    }    return 0;}在程序退出之前还要：NOTIFYICONDATA nid;nid.cbSize = sizeof(NOTIFYICONDATA);nid.hWnd = m_hWnd;nid.uID = IDI_SYSTEMTRAY;nid.uFlags = 0;::Shell_NotifyIcon(NIM_DELETE, &nid);
