为您找到与如何找出歌曲名相关的共32个结果:
在excel的使用中,你可以找出重复的内容,那可不可以找出不重复的内容呢?那小面跟小编一起去试试吧。
1.公司统计了各大区收到产品的人员信息。下表包含姓名、产品、地区、数量等等。
2.在E2单元格输入: =if(countif( ,就会显示相关函数的参数。
3.将公式输入完整: =IF(COUNTIF(A:A,A2)=1,A2,"") 关于COUNTIF函数的具体讲解,大家可以参考这篇教程:http://www.wordlm.com/Excel/2007/3517.html
4.回车,得到结果,是个空白,稍后作解释。然后利用单元格填充的方法,将整张表格填充完成。

excel一组数据中怎么能一下把最大找出来,就由小编来教你吧。
①启动Excel2013,选中表格数据区域,单击菜单栏--开始--条件格式--新建规则。
②选择使用公式确定要设置的单元格格式,输入下面的公式,如图所示:单击格式按钮。
③设置单元格格式,这里,我就简单的改变其颜色。
④确定之后,北京地区的最高销售额相关信息就出来了,不止这样,我们在A1单元格输入广东,也会显示出广东最高销售额的信息。

当excel中有大量的数据的时候,如果要求你找出其中的最大值和最小值,你可能非常的苦恼,如果单个进行查找那是很麻烦的,而且也浪费时间,那怎样才能快速的找到最大值和最小值呢?下面小编教你在excel中快速找出最大值和最小值的方法,希望对你有帮助!
①启动Excel2013,鼠标选中数据区域,单击菜单栏--插入--数据透视表。
②弹出创建数据透视表对话框,因为第一步中我们已经选中了数据区域,这里,直接确定即可。
③在右侧的数据透视表字段中,勾选地区和订购数量,右击求和项:订购数量,从弹出的右键菜单中依次选择值汇总依据,最大值。
④同上述步骤,在另外一个求和项:订购数量上右击,从弹出的右键菜单中依次选择值汇总依据,最小值。
⑤这样华东华南地区的最大最小值就显示出来了,复制,然后在另外一个表中,按下Ctrl+V粘贴就行了。

你想了解Linux基础:如何找出你的系统所支持的最大内存吗,下面,小编立即为您献上教程。
大多数情况下你可以从BIOS、产品目录或者干脆手动找出你的系统所持的最大内存。这里,我们介绍一种简单有用的技巧——使用dmidecode来找出系统支持的最大内存,这样你就无需打开机箱或者参照BIOS和产品目录了。
什么是 dmidecode?
就像你可能知道的一样, dmidecode是一个将计算机DMI(又名SMBIOS)表的内容转换为可读格式的工具。这个表包含了系统硬件组件的介绍以及其他一些如序列号和IOS版本等有用的信息。使用dmidecode你能够获取此项信息,而无需去探测真实的硬件。
找出你的系统所支持的最大内存
请确定你已经在系统中安装了dmidecode,我觉得你的操作系统应该已经自动安装过了,不过并不非常确定。
在基于Deb的系统中安装
1sudo apt-get install dmidecode
在基于RPM的系统中安装
1sudo yum install dmidecode
在SUSE/openSUSE中安装
1sudo zypper in dmidecode
好了,我们已经安装了dmidecode,接下来让我们找出支持的最大内存。输入以下命令:
1sudo dmidecode -t 16
输出样本
11# dmidecode 2.12
SMBIOS 2.6 present.
Handle 0x0014, DMI type 16, 15 bytes

Number Of Devices: 2
就像你看到的,我的系统支持最大内存到16G,并且有两个内存插槽,简单吧?
接下来,让我们找出现在已经安装的内存的详细信息。

大多数情况下你可以从BIOS、产品目录或者干脆手动找出你的系统所持的最大内存。这里,我们介绍一种简单有用的技巧——使用dmidecode来找出系统支持的最大内存,这样你就无需打开机箱或者参照BIOS和产品目录了。让我们一起去看看。
什么是 dmidecode?
就像你可能知道的一样, dmidecode是一个将计算机DMI(又名SMBIOS)表的内容转换为可读格式的工具。这个表包含了系统硬件组件的介绍以及其他一些如序列号和IOS版本等有用的信息。使用dmidecode你能够获取此项信息,而无需去探测真实的硬件。
找出你的系统所支持的最大内存
请确定你已经在系统中安装了dmidecode,我觉得你的操作系统应该已经自动安装过了,不过并不非常确定。
在基于Deb的系统中安装
sudo apt-get install dmidecode
在基于RPM的系统中安装
sudo yum install dmidecode
在SUSE/openSUSE中安装
sudo zypper in dmidecode
好了,我们已经安装了dmidecode,接下来让我们找出支持的最大内存。输入以下命令:
sudo dmidecode -t 16
输出样本
# dmidecode 2.12
SMBIOS 2.6 present.

就像你看到的,我的系统支持最大内存到16G,并且有两个内存插槽,简单吧?
接下来,让我们找出现在已经安装的内存的详细信息。
sudo dmidecode -t 17

就像上边输出的一样,我在插槽1里边安装了一个内存条。内存大小为4G,类型为DDR3,速度为1067 MHz。
同样的,我们可以通过下边命令得到完整的内存信息。
sudo dmidecode -t memory
sudo dmidecode -t memory | less
sudo dmidecode -t memory | more

电脑中毒了在哪个文件夹呢!当我们怎么找都找不到的时候,是不是想放弃!下面由读文网小编给你做出详细的电脑中毒文件夹查找介绍!希望对你有帮助!
打开我的电脑,上面菜单里选择工具--文件夹选项--查看--隐藏已知文件的扩展名,把这个勾上,再把显示所有文件和文件夹勾上,再把后缀为.exe的文件夹删除
你应该可以看见隐藏的真实的文件夹,然后对其右键属性,把隐藏勾掉改成只读就可以了,不需要什么专杀

面对着局域网中成百台电脑,一个一个地检测显然不是好办法。其实我们只要利用ARP病毒的基本原理:发送伪造的ARP欺骗广播,中毒电脑自身伪装成网关的特性,下面由读文网小编给你做出详细的找出ARP欺骗病毒母机的方法介绍!希望对你有帮助!
这种方法比较简便,不利用第三方工具,利用系统自带的ARP命令即可完成。当局域网中发生ARP欺骗的时候,ARP病毒电脑会向全网不停地发送ARP欺骗广播,这时局域网中的其它电脑就会动态更新自身的ARP缓存表
将网关的MAC地址记录成ARP病毒电脑的MAC地址,这时候我们只要在其它受影响的电脑中查询一下当前网关的MAC地址,就知道中毒电脑的MAC地址了,查询命令为 ARP -a,需要在cmd命令提示行下输入。输入后的返回信息如下:
Internet Address Physical Address Type
192.168.0.1 00-50-56-e6-49-56 dynamic
这时,由于这个电脑的ARP表是错误的记录,因此,该MAC地址不是真正网关的MAC地址,而是中毒电脑的MAC地址!这时,再根据网络正常时,全网的IP—MAC地址对照表,查找中毒电脑的IP地址就可以了。由此可见,在网络正常的时候,保存一个全网电脑的IP—MAC地址对照表是多么的重要。可以使用nbtscan工具扫描全网段的IP地址和MAC地址,保存下来,以备后用。

Excel经常会需要绘图来让工作表变得更好看,而07版本跟03版本的界面太不同,所以有很多用户都不太知道绘图工具在哪。接下来请欣赏读文网小编给大家网络收集整理的excel07版找出绘图工具的方法。
步骤1:首先我们打开一张空白的EXCEL2007图标,如图所示。
步骤2:然后点击”插入“选项卡,如图所示。
步骤3:不用管其它的,点击”形状“按钮,如图所示。
步骤4:然后在弹出的界面就会有各种各样的线条和箭头等图形,如图所示。
步骤5:我们随便选择一种,我们来画一个矩形,如图所示。
步骤6:这里是个有颜色的,如果我们要空白的怎么办呢?选中这个矩形,点击颜色填充,如图所示。
步骤7:选择白色,或者无填充颜色都可以,如图所示。
步骤8:是不是变成空白的矩形了呢,同样箭头和线条也可以选择颜色。

系统中同时运行的进程那么多,哪些是正常的系统进程,哪些是木马的进程,而经常被病毒木马假冒的系统进程在系统中又扮演着什么角色呢?下面由读文网小编给你做出详细的找出藏匿电脑病毒方法介绍!希望对你有帮助!
上文中提到了很多系统进程,这些系统进程到底有何作用,其运行原理又是什么?下面我们将对这些系统进程进行逐一讲解,相信在熟知这些系统进程后,就能成功破解病毒的“以假乱真”和“偷梁换柱”了。
svchost.exe
常被病毒冒充的进程名有:svch0st.exe、schvost.exe、scvhost.exe。随着Windows系统服务不断增多,为了节省系统资源,微软把很多服务做成共享方式,交由svchost.exe进程来启动。而系统服务是以动态链接库(DLL)形式实现的,它们把可执行程序指向scvhost,由cvhost调用相应服务的动态链接库来启动服务。我们可以打开“控制面板”→“管理工具”→服务,双击其中“ClipBook”服务,在其属性面板中可以发现对应的可执行文件路径为“C:WINDOWSsystem32clipsrv.exe”。再双击“Alerter”服务,可以发现其可执行文件路径为“C:WINDOWSsystem32svchost.exe -k LocalService”,而“Server”服务的可执行文件路径为“C:WINDOWSsystem32svchost.exe -k netsvcs”。正是通过这种调用,可以省下不少系统资源,因此系统中出现多个svchost.exe,其实只是系统的服务而已。
在Windows2000系统中一般存在2个svchost.exe进程,一个是RPCSS(RemoteProcedureCall)服务进程,另外一个则是由很多服务共享的一个svchost.exe;而在WindowsXP中,则一般有4个以上的svchost.exe服务进程。如果svchost.exe进程的数量多于5个,就要小心了,很可能是病毒假冒的,检测方法也很简单,使用一些进程管理工具,例如Windows优化大师的进程管理功能,查看svchost.exe的可执行文件路径,如果在“C:WINDOWSsystem32”目录外,那么就可以判定是病毒了。
explorer.exe
常被病毒冒充的进程名有:iexplorer.exe、expiorer.exe、explore.exe。explorer.exe就是我们经常会用到的“资源管理器”。如果在“任务管理器”中将explorer.exe进程结束,那么包括任务栏、桌面、以及打开的文件都会统统消失,单击“任务管理器”→“文件”→“新建任务”,输入“explorer.exe”后,消失的东西又重新回来了。explorer.exe进程的作用就是让我们管理计算机中的资源。
explorer.exe进程默认是和系统一起启动的,其对应可执行文件的路径为“C:Windows”目录,除此之外则为病毒。
iexplore.exe
常被病毒冒充的进程名有:iexplorer.exe、iexploer.exeiexplorer.exe进程和上文中的explorer.exe进程名很相像,因此比较容易搞混,其实iexplorer.exe是Microsoft Internet Explorer所产生的进程,也就是我们平时使用的IE浏览器。知道作用后辨认起来应该就比较容易了,iexplorer.exe进程名的开头为“ie”,就是IE浏览器的意思。
iexplore.exe进程对应的可执行程序位于C:ProgramFilesInternetExplorer目录中,存在于其他目录则为病毒,除非你将该文件夹进行了转移。此外,有时我们会发现没有打开IE浏览器的情况下,系统中仍然存在iexplore.exe进程,这要分两种情况:1.病毒假冒iexplore.exe进程名。2.病毒偷偷在后台通过iexplore.exe干坏事。因此出现这种情况还是赶快用杀毒软件进行查杀吧。
rundll32.exe
常被病毒冒充的进程名有:rundl132.exe、rundl32.exe。rundll32.exe在系统中的作用是执行DLL文件中的内部函数,系统中存在多少个Rundll32.exe进程,就表示Rundll32.exe启动了多少个的DLL文件。其实rundll32.exe我们是会经常用到的,他可以控制系统中的一些dll文件,举个例子,在“命令提示符”中输入“rundll32.exe user32.dll,LockWorkStation”,回车后,系统就会快速切换到登录界面了。rundll32.exe的路径为“C:Windowssystem32”,在别的目录则可以判定是病毒。
spoolsv.exe
常被病毒冒充的进程名有:spoo1sv.exe、spolsv.exe。spoolsv.exe是系统服务“Print Spooler”所对应的可执行程序,其作用是管理所有本地和网络打印队列及控制所有打印工作。如果此服务被停用,计算机上的打印将不可用,同时spoolsv.exe进程也会从计算机上消失。如果你不存在打印机设备,那么就把这项服务关闭吧,可以节省系统资源。停止并关闭服务后,如果系统中还存在spoolsv.exe进程,这就一定是病毒伪装的了。
限于篇幅,关于常见进程的介绍就到这里,我们平时在检查进程的时候如果发现有可疑,只要根据两点来判断:

在Excel中录入好数据以后为了补充说明都会画一些图进行说明,可能有些时候绘图工具隐藏了,需要我们找出来。下面是读文网小编带来的关于excel2013找出绘图工具的方法,希望阅读过后对你有所启发!
找出绘图工具步骤1:插入图形、艺术字等是绘图工具栏最常用的功能,这些命令被集中在excel2010的插入选项卡中。如下图所示。
找出绘图工具步骤2:编辑图片时需要调整线的颜色、粗线、形状。原来它们躲在“绘图工具”选项卡中,只是你只有选中插入的图片,这个选项卡才会出现。
找出绘图工具步骤3:当插入多个图形时,需要对它们进行对齐等操作,这些命令依旧在“绘图工具”选项卡中。
找出绘图工具步骤4:在绘图工具栏中还有一个命令:改变自选图形。通过它我们可以把单元格中的批注也设置成其他样式。但在默认的功能区们,我们找不到这个命令,它被excel2010雪藏了起来。
找出绘图工具步骤5:找回方法:文件 - excel选项 - 自定义功能区 - 查找到“更改图形”添加到右边的选项卡中。(选项卡或组需要是自定义的)

Win7右下角音量控制图标不见了,可以放出声音,在控制面板的调节系统音量里里可以调节音量,检查了声卡驱动也是正确的,下面读文网与大家分享下具体的找出方法Win7右下角音量控制图标。
一般情况下,我们只要重启桌面程序,声音图标就会回来了。操作如下:
(1)在任务栏右键, 选择“启动任务管理器”,如下图
(2)在进程标签页,选中explorer.exe,然后点击“结束进程”
结束完成后会是如下样子。
注意:如果这是不小心吧任务管理器关掉了,可以通过键盘Ctrl + Alt + Del 组合键,重新打开任务管理器。
(3)点击文件管理器的“文件”-“新建任务”
输入explorer或者explorer.exe. 然后确定
然后看声音图标是不是出现了

win7文件隐藏了怎么找出来?win7现在用的人越来越多,但win7界面和xp有很大不同,如果使用XP的方法,让win7显示隐藏文件夹不容易操作,下面读文网小编就给大家介绍下让win7显示隐藏文件夹的方法
1、选择“开始”→点击开始菜单栏中的“控制面板”。
2、选择控制面板中的“文件夹选项”,双击打卡,如图4所示:
3、剩下的步骤和方法一中的步骤3一样。
好啦!这样电脑中除了受保护的操作系统文件夹不能查看外,其他的文件、文件夹都通通无所遁形啦。

可能由于某些文件中了病毒,在杀毒软件查杀后,会将该文件所在的文件夹隐藏起来,不管自己怎么找都找不到。那么win7文件隐藏后怎么找出来呢?下面跟着读文网小编来一起了解下吧。
首先,打开“计算机”,在以前的XP中是叫“我的电脑”,从这点上看来MS也人性化了些了;
打开“计算机”后,点击“工具”菜单,从弹出的菜单中选择“文件夹选项”命令:
而对于没有菜单栏的WIN7系统中,我们可以按住ALT弹出菜单栏。或者点击“组织”,再选择“文件夹和搜索选项”命令:
接下来在打开的“文件夹选项”对话框中,单击“查看”,切换到“查看”选项卡中:
然后在下面的“高级设置”区域,取消“隐藏受保护的操作系统文件”前面的复选框;再选择下面的“显示隐藏的文件、文件夹和驱动器”单选项,如上图;
最后单击“确定”按钮保存设置既可;
我们再打开有隐藏文件的地方,可以发现,隐藏的文件已经显示出来了:
8当然,这些隐藏文件和正常的没有隐藏属性的文件是有区别的,隐藏的文件略有加白显示。

excel2003用函数找出数据最大值的方法
Excel中经常需要使用到函数进行寻找数据里最大值的记录,用函数具体该如何找出数据里的最大值记录呢?下面是读文网小编带来的关于excel2003用函数找出数据最大值的方法,希望阅读过后对你有所启发!
步骤1:我们打开excel,随便写一些数据,作为我们要查找最大值的操作对象,如下图所示:
步骤2:我们做一点修改,输入“最大的数”,然后把光标停留在“最大的数”后面的一个单元格中,点击红色方框中的“fx”,可以进入函数设置页面
步骤3:点击“fx”后,就进入“插入函数”的设置页面,如下图所示,我们就是在这里找我们要使用的函数
步骤4:我们要使用的max函数是属于“统计”类别的,所以我们需要在“选择类别”后面的下拉框中选择“统计”
步骤5:选择“统计”之后,在“选择函数”下面的函数列表中列出的都是关于“统计”的函数,我们选择我们要使用的“MAX”,之后点右下方的“确定”。
步骤6:完成第5步之后,就进入到“函数参数”的设置界面,我们删除Number1后面的内容,我们自己来选择我们的范围
步骤7:假设我们要查找的范围是本表格中的所有数据,那么我们要设置的第一个参数应该是表格中第一个数据,我们用鼠标点击第一个数据的值,会发现第一个参数就自动帮我们填入到Number1后面的输入框中了,如下图所示:
步骤8:之后我们在第一个参数后面手动输入冒号,冒号表示范围。如下图红色方框所示
步骤9:现在我们要做的是设置最后一个参数了,我们只要用鼠标点击一下表格最后面的一个数据就可以了,excel就会自动帮我们填写这个参数的值。
步骤10:所有的参数都设置好了,现在我们点“确定”按钮,就会关闭“函数参数”设置对话框,回到表格中,这是我们发现已经帮我们查找到最大的数值了。
