VC编程-隐藏某程序托盘的图标

VC中系统托盘图标的实现本文以实例代码的形式讲述了在VC中系统托盘图标的实现。

技术实现：在VC中实现系统托盘图标主要用到一个Shell_NotifyIcon系统API。

在本文中我们以对话框程序为例子实现系统托盘图标，步骤如下：1．在StdAfx.h中定义消息ID，如：#define MYWM_NOTIFYICON WM_USER+12．定义一个全局NOTIFYICONDATA变量，如：NOTIFYICONDATA g_nd;3．实现添加系统托盘图标函数，如：void CZTXClientDlg::AddSystrayIcon(){// 将图标放入系统托盘g_nd.cbSize = sizeof (NOTIFYICONDATA);g_nd.hWnd = m_hWnd;g_nd.uID = IDR_MAINFRAME;g_nd.uFlags = NIF_ICON|NIF_MESSAGE|NIF_TIP;g_nd.uCallbackMessage= MYWM_NOTIFYICON;g_nd.hIcon = m_hIcon;strcpy(g_nd.szTip, "知天下娱乐中心[V1.1]");Shell_NotifyIcon(NIM_ADD, &g_nd);}4．实现删除系统托盘图标函数，如：void CZTXClientDlg::DelSystrayIcon(){Shell_NotifyIcon(NIM_DELETE, &g_nd);5．重载WindowProc函数，如：LRESULT CZTXClientDlg::WindowProc(UINT message, WPARAM wParam, LPARAM lParam){// TODO: Add your specialized code here and/or call the base classswitch( message ){case MYWM_NOTIFYICON:if(lParam==WM_LBUTTONDBLCLK){AfxGetApp()->m_pMainWnd->ShowWindow(SW_SHOW);}else if(lParam==WM_RBUTTONDOWN){CMenu menu;//载入事先定义的选单menu.LoadMenu(IDR_TRADEMEMU);CMenu*pMenu=menu.GetSubMenu(0);CPoint pos;GetCursorPos(&pos);//加入SetForegroundWindow的目的为使用户点菜单之外时菜单可以消失::SetForegroundWindow(m_hWnd);pMenu->TrackPopupMenu(TPM_LEFTALIGN|TPM_RIGHTBU TTON,pos.x,pos.y,AfxGetMainWnd());}break;}return CDialog::WindowProc(message, wParam, lParam);6． OK，现在在我们的OnInitDialog函数中加入如下代码：AddSystrayIcon( );7．在窗口关闭函数中加入如下代码：DelSystrayIcon( );经测试可行!非常感谢!。

vc实现系统托盘图标Windows中，任务栏的右边(托盘)常驻有几个图标，如输入法切换图标、音量控制图标等系统图标，而一些在后台执行实时监控或其他任务的软件如金山词霸、瑞星杀毒软件等也只是在托盘上放一个小小的图标，几乎不占用本来就拥挤不堪的桌面，而且必要时我们还可以通过用鼠标点击图标对其进行菜单操作或激活其主窗口。

如果在我们编制的一些类似的在后台工作的实时监控软件里加入上述功能，无疑会使程序显得很有专业水准。

虽然有不少介绍系统托盘方面编程的文章，但大多是讲述如何在SDK下用Windows API编写的，这样做显然是非常烦琐的，本文以一个SDI（单文档界面）程序为例，讲述了在MFC框架程序中此类程序的实现过程。

[喝小酒的网摘]/a/1117.htm二、程序的设计思路在编制此类程序时，为了不干扰前台程序的运行界面和不显示不必要的窗口，应使其运行时的主窗口不可见。

同时，又要让用户知道该程序正在运行，并且能达到与用户进行交互的目的。

将一个图标显示在任务栏右端系统托盘区中并响应用户的鼠标动作是当前非常流行的方法。

要使程序的主窗口不可见，并且不在任务栏上出现任务按钮，需要分别设置主边框窗口的风格和扩展风格；另外，利用系统函数Shell_NotifyIcon可以将一个图标显示在任务栏的通告区中。

剩下的任务就是如何通过这个图标来响应用户的操作，可以象其他软件如WinAmp 一样通过弹出式菜单来完成同用户的交互。

三、程序的具体实现（一）主界面的隐藏前面已经提过，要求程序运行开始时主窗口不可见，同时也不出现在任务栏中，在SDK下是通过修改入口函数WinMain中的API函数 CreatWindow的参数来实现的，在MFC下已经对其进行了封装，使我们无法直接对WinMain函数内部进行访问与修改，不过可以通过MFC提供的另外一个接口--在主框架类的预创建窗口函数中设定主框架窗口的风格和扩展风格来实现之：BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs) {if( !CFrameWnd::PreCreateWindow(cs) )return FALSE;cs.style=WS_POPUP;cs.dwExStyle |=WS_EX_TOOLWINDOW;return TRUE;}其中，CREATESTRUCT结构中的style成员变量设定了主框架窗口的风格，在此设定为WS_POPUP；而dwExStyle成员变量则对主框架窗口的扩展风格做了描述，只需在原有基础上为其再增添一种WS_EX_TOOLWINDOW扩展属性即可使其不会出现在任务条上。

VC 实现显示、自动隐藏任务栏(SHAppBarMessage)VC 实现显示、自动隐藏任务栏(SHAppBarMessage)一、显示和隐藏任务栏要想对任务栏进行操作，首先当然需要获得任务栏的句柄，所以首先利用FindWindow 获取句柄，再操作示例代码：1、隐藏任务栏HWND hWnd = FindWindow(_T("Shell_TrayWnd"),NULL); ShowWindow(hWnd,SW_HIDE);2、显示任务栏HWND hWnd = FindWindow(_T("Shell_TrayWnd"),NULL);ShowWindow(hWnd,SW_SHOW); 二、自动隐藏任务栏和取消自动隐藏任务栏(隐藏于自动隐藏不同）需要利用一API 函数：SHAppBarMessage UINT_PTR SHAppBarMessage(DWORD dwMessage,PAPPBARDATA pData);参数说明：dwMessage 可以为下列参数ABM_ACTIVATEappbarABM_GETAUTOHIDEBAR 的appbar ABM_GETSTATE激活一个检索屏幕边缘检索最顶层的Microsoft Windows 任务栏ABM_GETTASKBARPOS 检索任务栏ABM_NEW 注册一个新的appbar ，该系统并发送一消息给appbarABM_QUERYPOS appbar 大小和屏幕位置ABM_REMOVE 取消注册一个appbar ，并从系统内部列表移出ABM_SETAUTOHIDEBAR 在屏幕边缘注册或取消注册appbarABM_SETPOS 设置appbar 的大小和屏幕位置ABM_SETSTATE appbar 为最顶层设置ABM_WINDOWPOSCHANGED 当appbar 得状态发送改变时向系统发送消息pData一个APPBARDATA 结构体示例代码：void AutoHideTaskBar(BOOL bHide){//这三句视情况加于不加#ifndef ABM_SETSTATE#define ABM_SETSTATE0x0000000a#endifLPARAM lParam;if(bHide == TRUE)lParam = ABS_AUTOHIDE;// 自动隐藏}else{lParam = ABS_ALWAYSONTOP;// 取消自动隐藏}APPBARDATA apBar;memset(&amp;apBar,0,sizeof(apBar));apBar.cbSize = sizeof(apBar); apBar.hWnd =FindWindow("Shell_TrayWnd",NULL);if(apBar.hWnd != NULL){apBar.lParam = lParam;SHAppBarMessage(ABM_SETSTATE,&amp;apBar); // 置任务栏自动隐藏}}调用AutoHideTaskBar(TRUE);//orAutoHideTaskBar(FALSE);//。

C#托盘应用详解一．托盘程序的主要步骤及解决方法：为什么说用Visual C#可以十分方便的做一个托盘程序，主要的原因是在.Net框架的软件开发包( .Net FrameWork SDK )中的WinForm组件中定义了一个专门用来开发托盘程序的组件--NotifyIcon组件。

下面就来介绍一下这个组件的具体用法和程序设计中的主要的技巧。

（1）.如何在程序运行后隐藏窗体：我们知道托盘程序运行后是无法看见主窗体的，他只会显示在工具栏上。

在用Visual C#设计此类程序的时候，可以用二种方法使得程序运行后不显示主窗体。

其中一种方法是重载主窗体中的OnActivated( )事件，OnActivated( )事件是在窗体激活的时候才触发的。

通过重载此事件可以达到隐藏主窗体的目的。

具体程序代码如下：protected override void OnActivated ( EventArgs e ){this.Hide ( ) ;}另外一种方法是在初始化主窗体的时候完成的，通过设定主窗体的属性来达到不显示的目的。

具体的程序代码如下：this.MaximizeBox = false ;this.MinimizeBox = false ;this.WindowState = System.Windows.Forms.FormWindowState.Minimized ;在本文介绍的程序中，使用了第二种方法。

（2）.如何为托盘程序设定显示图标：在NotifyIcon组件中有一个属性icon就是来设定托盘图标的，由于Visual C#是一个完全的OOP (面向对象)语言，在Visual C#中任何东西都可以作为对象来处理。

当然对应一个icon来说，也可以用对象的方法来处理他。

我们通过下列语句来得到一个icon对象：private Icon mNetTrayIcon = new Icon ( "Tray.ico" ) ;请注意：在编译好的程序中，必须要在同一个目录中有一个Tray.ico图标文件，否则程序运行时候会出错的。
