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
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); //移动界面位置
MoveWindow(0,300,30,150, 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(),0,100,2);
FreeLibrary(hInst);
}
3, //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////////
CFont myFont; //创建字体对象
//创建逻辑字体
myFont.CreateFont(40, //字体高度(旋转后的字体宽度)=56
10, //字体宽度(旋转后的字体高度)=20
2700, //字体显示角度=270°
0, //nOrientation=0
6, //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()/2+8,2, "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
