VC+++在ListView中添加右键菜单

使用弹出式菜单（PopMenu）弹出式菜单（PopMenu）大家都熟悉，在WIN98的桌面上单击鼠标右键弹出的菜单就是弹出式菜单。

通常情况下，弹出式菜单在鼠标右键单击时弹出，当然，也能够根据需要随时弹出。

在VC++5的MFC中，管理菜单的类叫CMenu。

下面我向大家介绍建立一个弹出式菜单的基本方法。

一、在资源编辑器中建立一个菜单资源新建一个菜单资源，比如把菜单的ID号为IDC_POPMENU。

此菜单有一项两层，即有一个可弹出的菜单项，而此菜单项的弹出内容即为将要建立的弹出式菜单的内容。

至于每一个菜单项的消息映射，和一般的菜单相同。

二、使用CMenu类对象CMenu类的成员函数较多，但建立弹出式菜单只需用到其中几个成员函数。

1、LoadMenu函数功能：从应用程式的可执行文档中加载菜单资源原型：BOOL LoadMenu( UINT nIDResource );其中nIDResource是菜单资源的ID号，这里用的是刚建立的IDC_POPMENU。

2、GetSubMenu函数功能：此函数用于得到子菜单的指针。

原型：CMenu* GetSubMenu( int nPos ) const;nPos为层数，0为第一层子菜单……以此类推。

由于我们需要的是“可弹出项”的第一层子菜单，因此用GetSubMenu(0)来得到第一层子菜单的类指针。

3、TrackPopupMenu函数功能：在指定位置显示弹出菜单，并跟踪所选择的项原型：BOOL TrackPopupMenu( UINT nFlags,int x,int y,CWnd* pWnd,LPCRECT lpRect = NULL );其中：nFlags为屏幕坐标属性和鼠标坐标属性屏幕坐标属性：TPM_CENTERALIGN 横向将菜单以x居中TPM_LEFTALIGN 横向将菜单以x左对齐TPM_RIGHTALIGN 横向将菜单以x右对齐鼠标按键属性（只在响应WM_CONTEXTMENU消息时有效）：TPM_LEFTBUTTON 连续按? 右键不会连续弹出菜单，鼠标右键不可用于选定菜单项TPM_RIGHTBUTTON 连续按鼠标右键会连续弹出菜单，鼠标右键可用于选定菜单项x，y均为屏幕坐标lpRect 菜单所占的区域。

在winform界面实现右键菜单功能

在winform界⾯实现右键菜单功能没接触之前,感觉模式⽐较困难,其实不然,其实只有短短的⼏部就可以实现呢!⼀、⾸先在页⾯新建contextMenuStrip 菜单项,然后再菜单⾥⾯添加你想要操作的步骤;⼆、就是补⾜⿏标右键事件；protected override void OnMouseUp(MouseEventArgs e){base.OnMouseUp(e);if (e.Button == MouseButtons.Right){contextMenuStrip.Show(this,e.Location);}}这样简单的⼏步就实现呢!当然这是简单的菜单项,如果想让你的菜单更加丰满炫丽,就要为菜单项添加样式呢！这⾥我也将某个菜单的样式代码附上,供⼤家参考!public class ToolStripRendererEx : ToolStripRenderer{private CaptureImageToolColorTable _colorTable;private static readonly int OffsetMargin = 24;private const string MenuLogoString = "";public ToolStripRendererEx() : base(){}public ToolStripRendererEx(CaptureImageToolColorTable colorTable): base(){_colorTable = colorTable;}protected virtual CaptureImageToolColorTable ColorTable{get{if (_colorTable == null){_colorTable = new

win8系统怎么给鼠标右键添加菜单功能

win8系统怎么给鼠标右键添加菜单功能
电脑平常操作中会通过鼠标右键菜单中的选项刷新、新建记事本、编辑图片或截图等等功能，在安装第三方软件时也是在鼠标“右键菜单”中新增功能，但有些功能需要用户自己去添加到菜单中才可以使用，那么你知道win8系统怎么给鼠标右键添加菜单功能吗?下面是店铺整理的一些关于win8系统给鼠标右键添加菜单功能的相关资料，供你参考。

win8系统给鼠标右键添加菜单功能的方法：
1、以Win8平台作为例子，把鼠标移动到屏幕的右下方，然后就直接打开Charm超级菜单，搜索并打开“运行”选项;
2、在运行命令框里面直接输入regedit字符，然后就手动打开注册表编辑器;
3、依次定位到HKEY_CLASSES_ROOTDirectoryBackgroundshell，在shell下面直接新建“项。

4、接着在上面的项目里面继续新建子“项”：command，双击这个键值，在里面手动输入QQ、截图以及记事本等各个应用程序的系统路径;
上面所有的操作都完整之后，就已经成功的给ghost win7、Win8.1右键菜单添加了QQ、记事本、截图工具以及滑动关机等多个功能，如下：

LabCVI常见问题及解决方法

LabCVI常见问题及解决方法1.使用CVI9.0调用由VC++6.0编写的DLL，该DLL在VC中调用是可以的，输出方式也是C语言的。

但是在CVI中调用该DLL时，总是提示missing prototype，如何解决？答：设置BUILD OPTION在options->Build optionsc language options中取消Require function prototypes的检测2.CVI中如何向设计好的word表格中添加文字和数据？答：先在表格中需要添加文字和数据的地方做一个“书签”，在CVI中打开该文档后，使用Word_GetProperty (currSelHandle, NULL, Word_SelectionBookmarks, CAVT_OBJHANDLE, &rangeHandle);获得“书签”信息，然后再向该“书签”处添加文字。

3.CVI中如何将波形图控件的图片放到剪贴板中？答：首先使用GetCtrlDisplayBitmap (panel, FORCEPANEL_GRAPH, 1, &bitmap);获得波形图控件的图片，然后使用ClipboardPutBitmap (bitmap);将图片放入到剪贴板中。

4.CVI中是否支持指向函数的指针，如何实现？答：可以实现，如下例：int(*pmax)(int a, int b);int x,y,z;pmax=max;printf("input two numbers:\n");scanf("%d%d",&x,&y);z=(*pmax)(x,y);5.CVI中如何使用非NI公司的硬件产品？该公司提供了一个fp文件。

答：一般来说通常可以调用产品销售商提供的动态链接库，有些大公司也提供fp文件，该文件可以直接使用，就可以达到使用硬件的目的了。

在使用前，可以直接将该文件添加入项目中，也可以在Library中定制fp文件的加载。

LabwindowsCVI鼠标右键实现菜单功能
（1）在主界面下，新建一个界面，菜单Create中，选择Panel..，直接就生成一个新的面板，双击新建的面板，修改参数。

图1 右键菜单面板参数设置界面
如图1所示，设置界面的名称代码，Constant name 为PANEL_MENU，面板名称Panel title 为“右键菜单”。

（2）为该面板新建菜单，有两种方法，一种是通过软件的菜单Create中Menu Bar...菜单进行新建菜单，一种方法是右键点击PANEL_MENU面板界面的空白处，选择“Menu Bar...”新建菜单。

如图2所示。

按照图中进行设置你需要的菜单内容。

图2 菜单设置界面
（3）在程序启动后，在main函数中添加代码，获取菜单所在界面的句柄，不用该界面。

其代码如下：
int menupanelHandle; //初始化界面句柄
if ((menupanelHandle = LoadPanel (1, "NaI_IEC.uir",
PANEL_MENU)) < 0) //获取界面句柄
return -1;
（4）在主界面中，设置回调函数，设置方式见第1节讲解。

然后在回调函数中添加鼠标右键点击事件。

并在该事件中添加右键菜单源代码，如下：
int a; //初始化菜单句柄变量
case EVENT_RIGHT_CLICK: //右键点击事件
a = GetPanelMenuBar(menupanelHandle); //获得菜单句柄
RunPopupMenu(a,MOR_MENU_MENU,panelHandle,eventData
1,eventData2,0,0,0,0);//显示右键菜单
break;
（5）编译，完成右键菜单功能，如图3所示。
