ALT+TAB切换时小图标的添加 界面透明 屏幕大小 竖行字体 进程信息

一，ALT+TAB切换时小图标的添加
 Dlg类中添加变量
protected:
    HICON m_hIcon;

#define IDR_MAINFRAME                   128
ICON            IDR_MAINFRAME,IDC_STATIC,,,,
// Icon with lowest ID value placed first to ensure application icon
// remains consistent on all systems.
IDR_MAINFRAME           ICON    DISCARDABLE     "res\\crtApp.ico"

 构造函数中加载
m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);
 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

 使用
// Draw the icon
dc.DrawIcon(, , 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()
 获取屏幕大小
int w = GetSystemMetrics(SM_CXSCREEN);
int h = GetSystemMetrics(SM_CYSCREEN);
 界面透明
SetWindowPos(&wndTopMost,,,,,SWP_SHOWWINDOW); //移动界面位置
MoveWindow(,,,, TRUE); //移动界面位置
//VS2003以上版本
       //SetWindowLong(GetSafeHwnd(),GWL_EXSTYLE,GetWindowLong(GetSafeHwnd

(),GWL_EXSTYLE)|WS_EX_LAYERED);
       //SetLayeredWindowAttributes(0,200,LWA_ALPHA);
       //VS2003以下版本
       SetWindowLong(GetSafeHwnd(), GWL_EXSTYLE, GetWindowLong(GetSafeHwnd(), 

GWL_EXSTYLE) |0x00080000);
       HINSTANCE hInst = LoadLibrary(_T("User32.dll"));
       if (hInst)
       {
           typedef BOOL (WINAPI *MyFun)(HWND,COLORREF,BYTE,DWORD);
           MyFun myfun = NULL;
           myfun = (MyFun)GetProcAddress(hInst, "SetLayeredWindowAttributes");
           if (myfun)
               myfun(GetSafeHwnd(),,,);
           FreeLibrary(hInst);
       }
, //竖行字体
Dlg::OnPaint()
{

    CPaintDC dc(this);// device context for painting
    CRect rtClient;
    GetClientRect(rtClient); //获取客户区尺寸、位置信息

    /////// 利用CFont::CreateFont(...)函数实现竖写汉字////////

        , //字体显示角度=270°
        , //nOrientation=0
        , //字体磅数=10
        FALSE, //非斜体
        FALSE, //无下划线
        FALSE, //无删除线
        DEFAULT_CHARSET, //使用缺省字符集
        OUT_DEFAULT_PRECIS, //缺省输出精度
        CLIP_DEFAULT_PRECIS,//缺省裁减精度
        DEFAULT_QUALITY, //nQuality=缺省值
        DEFAULT_PITCH, //nPitchAndFamily=缺省值
        "@system"); //字体名=@system
    CFont *pOldFont=dc.SelectObject(&myFont);//选入设备描述表 

    //在客户区适当位置输出文字
    dc.TextOut(rtClient.Width()/+,, "单击返回主界面");
    dc.SelectObject(pOldFont); //将myFont从设备环境中分离
    myFont.DeleteObject(); //删除myFont对象
/*
    /////////// 利用LOGFONT结构实现竖写汉字//////////////
    LOGFONT lf; //定义字体结构
    lf.lfWeight=8; //字体磅数=10
    lf.lfHeight=20; //字体高度(旋转后的字体宽度)=56
    lf.lfWidth=10; //字体宽度(旋转后的字体高度)=20
    lf.lfUnderline=FALSE; //无下划线
    lf.lfStrikeOut=FALSE; //无删除线
    lf.lfItalic=FALSE; //非斜体
    lf.lfEscapement=2700; //字体显示角度=270°
    lf.lfCharSet=DEFAULT_CHARSET; //使用缺省字符集
    strcpy(lf.lfFaceName,"@system"); //字体名=@system
    CFont myLogFont; //定义字体对象
    myLogFont.CreateFontIndirect(&lf); //创建逻辑字体
    pOldFont=dc.SelectObject(&myLogFont);//选入设备描述表
    //在客户区适当位置输出文字
//    dc.TextOut(rtClient.Width()/2+5,rtClient.Height()/32, "点击返回主界面");
    dc.SelectObject(pOldFont); //将myFont从设备环境中分离
    myLogFont.DeleteObject(); //删除myLogFont对象
