一，ALT+TAB切换时小图标的添加 1 Dlg类中添加变量 protected: HICON m_hIcon; #define IDR_MAINFRAME 128 ICON IDR_MAINFRAME,IDC_STATIC,11,17,20,20 // Icon with lowest ID value placed first to ensure application icon // remains consistent on all systems. IDR_MAINFRAME ICON DISCARDABLE "res\crtApp.ico" 2 构造函数中加载 m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME); 3 初始化 SetIcon(m_hIcon, TRUE); // Set big icon ALT+TAB SetIcon(m_hIcon, FALSE); // Set small icon 左上角小图标 4 使用 // Draw the icon dc.DrawIcon(100, 100, m_hIcon); // The system calls this to obtain the cursor to display while the user drags // the minimized window. Dlg::OnQueryDragIcon() { return (HCURSOR) m_hIcon; } 二 Dlg::OnInitDialog() 1 获取屏幕大小 int w = GetSystemMetrics(SM_CXSCREEN); int h = GetSystemMetrics(SM_CYSCREEN); 2 界面透明 SetWindowPos(&wndTopMost,0,300,30,150,SWP_SHOWWINDOW);
