程序最小化到托盘

VC++6.0中实现将应用程序的图标加入到Windows的系统托盘中（就是为应用程序在桌面右下角添加一个图标，和QQ类似）有位老兄说我乱贴，可能这位老兄已经看得眼花缭乱了，Shell_NotifyIcon 是一个Windows SDK的一个函数，只要你在windows下编程，不管你是BCB、VC、VB，都可以调用它来实现托盘图标，只是调用方法不同罢了。

常常能见到一些优秀的软件在运行后会将其应用程序图标加入到系统托盘中。

如果能将自己编写的应用程序的图标也加入到系统托盘中，将会使你的程序显得很有专业水准。

其实这并不困难，与系统托盘通信的函数只有一个：Shell_NotifyIcon (UINT message, NOTIFYICONDATA &m_nid);首先看一下该函数的两个参数。

第一个参数message可以取以下值：NIM_ADD 向托盘中加入一个图标； NIM_MODIFY 修改托盘中的图标；NIM_DELETE 从托盘中删除一个图标；第二个参数m_nid是NOTIFYICONDATA结构的一个引用。

该结构的原型如下：typedef struct _NOTIFYICONDATA{DWORD cbSize;// 结构的大小，必须在程序中给出HWND hWnd; //是你程序中将要接收托盘消息的窗口句柄UINT uID; // 应用程序中定义的托盘图标ID，此参数用作标识UINT uFlags; //设置属性，低三位有意义，0--7,如下：//第一位//#define NIF_MESSAGE 0x1 // uCallbackMessage参数有效//第二位//#define NIF_ICON 0x2 // hIcon参数有效//第三位//#define NIF_TIP 0x4 // szTip参数有效UINT uCallbackMessage; // 自定义的消息ID值，一定不要与以有的消息ID相重。

任意窗口“缩身”托盘有办法

任意窗口“缩身”托盘有办法
作者：南溪
来源：《电脑爱好者》2018年第07期
首先，我们可以用TrayIt！软件来解决。

软件运行首先会出现英文向导界面（图1）。

点击OK按钮之后，可用多种方法，轻松地将任意窗口最小化到系统托盘上。

打开一个窗口后，按住Shift不放，再点窗口的最小化按钮，可将该窗口图标最小化到系统托盘区域。

上述方法可让窗口临时最小化到系统托盘。

若要将窗口图标永久驻留系统托盘，可在上述已置于系统托盘的图标上单击鼠标右键，然后在快捷菜单中选择“Place in System Tray”命令（图2）。

或者在TrtayIt！主窗口选中要永久驻留系统托盘的窗口条目，然后点击工具栏上的第四个按钮，效果相同（图3）。

此外，還可以右键单击窗口边框右上角的最小化图标，然后选择“Place in System Tray”命令（图4）。

要最大化地发挥作用，还需通过Options窗口进行必要的设置。

先选择“Load TrayIt！ at Startup”让软件随系统自动启动，选择“Always start minized”启动程序后自动最小化；将Grouping分组下的复选框选中，将同类程序图标分为一组；若选择“Hold instead of minizing a windows to the tray”，则以Shift键来代替Ctrl键，之后按下Shift键并点击最小化按钮，才可将图标最小化到系统托盘（图5）。

扩展阅读
我们还可以用DM2这个比较有特色的软件最小化窗口。

它不但可以将窗口最小化到系统托盘上，还可以将窗口最小化为浮动图标。

与此同时，还可以设置窗口的透明度和优先级。

最小化到托盘

Private Sub Form_Resize()
If Me.WindowState = vbMinimized Then
cSysTray1.InTray = True
Me.Visible = FalseEnd If
End SLeabharlann b 点击托盘图标后让程序显示出来，如下：
Private Sub cSysTray1_MouseDown(Button As Integer, Id As Long)
Me.WindowState = vbNormal
Me.Visible = True
cSysTray1.InTray = False
Me.SetFocus
End Sub
然后在自己的VB程序中添加改控件(工程-部件-浏览)。
最好把这个ocx放到C:\WINDOWS\system32。
改控件的属性InTray属性用来设置是否显示在托盘中，True为显示在托盘，False为不显示。TrayIcon属性是在托盘中显示的图标式样。TrayTip属性是鼠标移到改控件上面显示的提示文字。如果要使程序最小化时显示到托盘，如下：
单击“最小化”按钮（标题栏的右边）将窗口缩小为任务栏上右边的图标，同时隐藏原窗体。单击或者右键托盘化的图标，可以重现原窗体。
vb中有部分api可以实现将窗体最小化的功能，但是非常繁琐。这里有一个非常简单的办法：可以用微软封装好的控件来实现，不过该控件并不在VB安装目录中，需要找到VB的安装盘(不是安装以后的目录)的COMMON\TOOLS\VB\UNSUPPRT\SYSTRAY目录，将Systray目录拷到硬盘上面并编译为ocx控件（编译前记得要先把只读属性修改掉，有时候会提示要先保存，直接保存。），

最小化到托盘

系统最小化到托盘一、托盘简介所谓的“托盘”，在Windows系统界面中，指的就是下面任务条右侧，有系统时间等等的标志的那一部分。

在程序最小化或挂起时，但有不希望占据任务栏的时候，就可以把程序放到托盘区。

二、托盘编程相关函数其实，把程序放到托盘上的本质就是先在托盘区绘制一个图标，然后把程序隐藏不见，再对托盘的图标进行消息处理，就可以了。

绘制图标以及确定图标所传送消息的函数只有一个，WINSHELLAPI BOOL WINAPI Shell_NotifyIcon(DWORD dwMessage,PNOTIFYICONDATA pnid);这个函数负责向系统传递消息，以添加、修改或删除托盘区的图标。

她的返回值是个布尔类型的。

就是说，如果返回0才成功。

参数dwMessage 是表示这个函数的应用功能是哪一方面，是添加、删除，还是修改图标。

如果是添加，则它的值为NIM_ADD；删除则是NIM_DELETE；而修改是NIM_MODIFY。

参数pnid就是具体的和程序在托盘区的图标有关系的结构了。

它的定义如下：typedef struct _NOTIFYICONDATA {DWORD cbSize;HWND hWnd;UINT uID;UINT uFlags;UINT uCallbackMessage;HICON hIcon;char szTip[64];} NOTIFYICONDATA, *PNOTIFYICONDATA;下面就对该结构各个参数进行刨析：cbSize : 结构的长度，用“位”来做单位。

一般在程序中，我们用(DWORD)sizeof(NOTIFYICONDATA) 给它赋值。

HWnd : 一个句柄，如果对托盘中的图标进行操作，相应的消息就传给这个句柄所代表的窗口。

大多数情况下是this->m_hWnd。

uID : 在工程中定义的图标IDuFlags : 这个成员标志着其他哪些成员的数据是有效的，分别为NIF_ICON, NIF_MESSAGE, NIF_TIP，分别代表着数据有效的成员是hIcon, uCallbackMessage, szTip。

VB窗体如何缩小到系统任务栏

如何使用直接从 Visual Basic 系统任务栏本文演示了如何充分利用 Windows 系统送纸器或使用 Visual Basic 的任务栏通知区域。

它将您选择的图标放入任务栏通知区域时鼠标 rested 通过它，将还原应用程序时单击了，并将显示一个弹出式菜单将显示您选择的工具提示的时用鼠标右键单击。

这是所有可能引起的直接处理回调的 Visual Basic 的能力，因此利用完全Shell_NotifyIcon 函数的 Shell32.dll 由被导出。

利用VB实现系统托盘技术

利用VB实现系统托盘技术作者：赵汝苓来源：《中国新通信》2017年第05期【摘要】通过调用API函数实现系统托盘技术，主要涉及到API的几个常用函数的声明和调用，再结合VB本身的特征综合运用。

【关键词】 API 系统托盘消息机制系统托盘常指Windows任务栏的状态区域，系统时钟、音量控制等程序都在系统托盘中，一些应用程序在安装完后也将它们本身的图标放入了其中。

一般来说，系统托盘驻留程序是在计算机后台运行，如瑞星、MSN等。

系统托盘主要以特殊的小图标在任务栏右边时间的区域出现，作为程序运行的一个标志，我们可以通过使用小图标所弹出的菜单来控制应用程序状态，可实现修改该图标、窗口复位、最大化、最小化及关闭程序等功能。

利用VB调用API可以实现功能比较完整的托盘程序，牵涉到Shell_NotifyIcon、SendMassage、CallWindowProc、SetWindowLong等API函数，其中Shell_NotifyIcon是主要的函数，它用来添加、删除、更改系统托盘区的图标，SendMassage、CallWindowProc、SetWindowLong函数，通过WINDOWS操作系统的消息机制，实现对应用程序的控制。

一、先介绍相关的API函数、关键字1、Shell_NotifyIcon用于添加、删除、更改系统托盘区的图标；2、SendMassage用于将一条消息发给某个窗口；3、CallWindowProc用于发送消息到一个窗口过程；4、SetWindowLong 用于使窗口结构中为指定的窗口设置属性，SetWindowLong函数作用是取得默认窗口过程的地址，然后转向自定义的窗口过程的地址。

5、消息机制。

Windows消息控制中心一般是三层结构，其顶端就是Windows内核。

Windows内核维护着一个消息队列，第二季控制中心从这个消息队列中获取自己管辖的消息，后作出处理，有些消息直接处理掉，有些还要发送给下一级窗体或控件。

VB6.0实现窗体最小化时到系统托盘区

VB6.0将窗体最小化到系统托盘区使用说明:共有两个方法，经个人实际测试（环境:xpsp3 vb6.0）第二个控件法最有效果，第一个方法在启动时确实在右下角，但是弹出后再次最小化就跑到屏幕左下角了，无法最小化，不知道是啥原因，希望大家改进代码。

本人力荐第二种小巧有效简单的方法。

----------------------------------------------------------------------------------------------------方法一托盘，亦即程序最小化后程序图标隐藏到屏幕右下角的任务栏里。

这种最小化方法比普通的最小化节约空间，因此备受欢迎，很多软件都具有这样的功能。

在VB中，可用API 函数来实现托盘功能，但比较复杂,不太好操作。

相对而言采用一种非常简单易行的方法：控件法，才是最适合最方便的。

下面要使用已被微软封装好的控件:csystray1(名称可自定)。

说到控件，大家可能要皱眉头了：去哪找呀？放心！这个控件就躺在你的VB安装盘里（目录为:COMMON\TOOLS\VB\UNSUPPRT\SYSTRAY）！不过，得处理一下：请在Tool 文件夹里查找一个名叫Systray的目录，将它拷贝到硬盘，用VB打开该目录下的工程，必要的话可作些改进（如更换图标、添加功能等），然后编译成ocx控件，可以随意命名。

为方便使用起见，最好编译到Windows\System目录下。

好了，现在我们就可以在我们的程序中使用此控件来轻松实现托盘功能了。

vb中添加控件的方法就不用我说了吧？----------------------------------------------------------------------------------------------------------控件的属性和事件浅析:该控件的InTray属性是用来设置是否显示在托盘中，True为显示在托盘，False为不显示；该控件的TrayIcon属性是在托盘中显示的图标式样；该控件的TrayTip属性是鼠标移动到该控件上面时，显示的提示文字；该控件的重要事件是几个我们常用的鼠标事件：按下、放开、移动、双击，编程时就是利用这些事件达到在任务栏中控制程序的目的。

大白话系列-C#窗体最小化到托盘功能实现

大白话系列-C#窗体最小化到托盘功能实现大白话系列宗旨：打破自身基础高低的壁垒，用最简单白话的语言，让最低基础的童鞋也能轻松编程。

项目描述：在 C # 中，窗体的右上角分别为“最小化”、“最大化”、“关闭”，而在我们选择“最小化”的时候，常常需要的就是在电脑的右下角托盘上显示图标代表该窗体没有被关闭。

本项目旨在通过代码的添加实现窗体最小化到电脑托盘的功能。

环境：VS2010、一个ico图标详细步骤：【完整代码附在文档最后】一、新建C #项目1、找到并打开VS2010软件，新建项目。

2、在弹出的窗口中左侧选择Visual C#下的Windows，然后在右侧选择“Windows窗体应用程序”，然后在下侧修改项目名称。

点击确定，即创建了一个窗体Form1。

二、notifyIcon控件添加及属性修改1、向窗体中添加notifyIcon控件。

在主界面左侧找到工具箱（若无工具箱，可在主界面“视图”选项卡下选择“工具箱”即可显示），在工具箱中找到notifyIcon控件双击，即可添加控件，我们可以看到该控件添加之后不在窗体内部，而是在窗体下方的区域，这部分控件叫做后台控件。

该控件的作用是在电脑右下角任务区显示图标。

2、修改notifyIcon控件属性。

点击notifyIcon控件，在右侧属性栏中修改该控件的属性。

首先，修改控件的“Text”属性为“大白话系列”。

然后，修改控件的“Icon”属性，这表示窗体最小化之后需要在电脑右下角展示的图标，在此之前需要把我们之前准备ico图标放入所建立项目的文件夹中。

点击Icon属性右边的灰色方框，以选择准备好的ico图标。

三、进入代码编写【完整代码附在文档最后】1、给notifyIcon控件添加代码。

选中notifyIcon控件，在右侧属性部分点击事件按钮，然后，在下面的事件列表中双击“Click”右边的空白框，即进入了notifyIcon控件的Click事件代码编辑部分。

如何使程序最小化到系统托盘

如何使程序最小化到系统托盘VC编写的应用程序希望像qq，千千静听，暴风影音那样程序最小化时在系统托盘中显示而不是在任务栏中。

如下：1.在基于对话框的程序的头文件中添加成员变量NOTIFYICODATA m_nid2.自定义消息函数OnShowTask1)首先在头文件中定义 #define WM_SHOWTASK WM_USER+12)在头文件映射中在添加afx_msg LRESULT OnShowTask(WPARAM wParam,LPARAM lParam)3)在源文件中的消息映射队列中添加ON_MESSAGE （WM_SHOWTASK，OnShowTask)4)在原文件中添加自定义消息函数定义：LRESULT CMediaPlayerDialog::OnShowTask(WPARAM wParam,LPARAM lParam){if(wParam != IDR_MAINFRAME)return 1;switch(lParam){case WM_RBUTTONUP: // 右键起来时弹出菜单{LPPOINT lpoint = new tagPOINT;::GetCursorPos(lpoint); // 得到鼠标位置CMenu menu;menu.CreatePopupMenu(); // 声明一个弹出式菜单menu.AppendMenu(MF_STRING, WM_DESTROY, "退出(&X)");menu.TrackPopupMenu(TPM_LEFTALIGN,lpoint->x ,lpoint->y, this);HMENU hmenu = menu.Detach();menu.DestroyMenu();delete lpoint;}break;case WM_LBUTTONDBLCLK: // 双击左键的处理{this->ShowWindow(SW_SHOWNORMAL); // 显示主窗口}break;}return 0;}3.在程序的InitDialog函数中添加如下代码：//---------------------------托盘显示初始化---------------------------------//m_nid.cbSize = (DWORD)sizeof(NOTIFYICONDATA);m_nid.hWnd = this->m_hWnd;m_nid.uID = IDR_MAINFRAME;m_nid.uFlags = NIF_ICON | NIF_MESSAGE | NIF_TIP ;m_nid.uCallbackMessage = WM_SHOWTASK; // 自定义的消息名称m_nid.hIcon = LoadIcon(AfxGetInstanceHandle(),MAKEINTRESOURCE(IDR_MAI NFRAME));strcpy(m_nid.szTip, "自制播放器"); // 信息提示条为"服务器程序"Shell_NotifyIcon(NIM_ADD, &m_nid); // 在托盘区添加图标4.重载对话框程序的WM_SIZE消息void CMediaPlayerDlg::OnSize(UINT nType, int cx, int cy){CDialog::OnSize(nType, cx, cy);// TODO: Add your message handler code hereif(nType == SIZE_MINIMIZED){ShowWindow(SW_HIDE); // 当最小化时，隐藏主窗口}}5.重载WM_DESTROY消息，关闭程序时关闭托盘上的程序图标void CMediaPlayerDlg::OnDestroy(){CDialog::OnDestroy();// TODO: Add your message handler code here// 系统关闭时在托盘区删除图标Shell_NotifyIcon(NIM_DELETE, &m_nid);// return CDialog::DestroyWindow();}。

VB实现窗口最小化到任务栏

要实现窗口最小化必须满足以下条件:1:按下最小化按钮,窗体不可见2:最小化后,最小化窗体的图标必须出现在任务栏的通知区域中3:当双击通知区域中的图标时,窗体又显示出来,同时通知区域中的图标消失.要满足上面的条件:1:首先屏蔽窗体中系统自带的最小化图标,即Form.MinButton=False2:声明1个API函数:Public Declare Function Shell_NotifyIcon Lib "shell32.dll" Alias " Shell_NotifyIconA" (ByVal dwMessage As Long, lpData As NOTIFYICONDA TA) As Long注意:上面这个API函数在XP中没有别名,将别名去掉后为:Public Declare Function Shell_NotifyIcon Lib "shell32.dll"(ByVal dwMessage As Long, lpData As NOTIFYICONDA TA) As Long3:声明7个常数:Public Const NIM_ADD = &H0Public Const NIM_DELETE = &H2Public Const NIF_ICON = &H2Public Const NIF_MESSAGE = &H1Public Const NIF_TIP = &H4Public Const WM_MOUSEMOVE = &H200Public Const WM_LBUTTONDBLCLK = &H2034:定义1个NOTIFYICONDA TA类型Public Type NOTIFYICONDATAcbSize as LonghWnd as LonguId as LonguFlags as LonguCallBackMessage as LonghIcon as LongszTip as StringEnd Type5:声明一个nid的类型Public nid as NOTIFYICONDA TA思路清晰后,开始编写代码1:在窗体中画1个Command,它的Caption属性为:"最小化"2:将窗体Form的MinButton的属性设为:"False"3:在窗体中添加1个模块,模块中的代码为:Public Declare Function Shell_NotifyIcon Lib "shell32.dll"(ByVal dwMessage As Long, lpData As NOTIFYICONDA TA) As LongPublic Const NIM_ADD = &H0Public Const NIM_DELETE = &H2Public Const NIF_ICON = &H2Public Const NIF_MESSAGE = &H1Public Const NIF_TIP = &H4Public Const WM_MOUSEMOVE = &H200Public Const WM_LBUTTONDBLCLK = &H203Public Type NOTIFYICONDATAcbSize as LonghWnd as LonguId as LonguFlags as LonguCallBackMessage as LonghIcon as LongszTip as StringEnd TypePublic nid as NOTIFYICONDA TA4:编写Command的单击事件:Private Sub Command1_Click()nid.cbSize = Len(nid)nid.uId = vbNullnid.hWnd = Me.hWndnid.uFlags = NIF_TIP Or NIF_MESSAGE Or NIF_ICONnid.uCallBackMessage = WM_MOUSEMOVEnid.hIcon = Me.Iconnid.szTip = "窗体最小化"Shell_NotifyIcon NIM_ADD, nidMe.HideEnd Sub5:编写窗体的MouseMove事件:Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single) Dim msg As Longmsg = X / 15If msg = WM_LBUTTONDBLCLK ThenMe.ShowShell_NotifyIcon NIM_DELETE, nidEnd IfEnd Sub按F5启动,单击Command,看看通知区域中是不是多了个窗体的图标?双击该图标,窗体又显示出来了!如何做到当我们单击窗口的最小化按钮时，窗口先最小化到任务栏成为按钮，然后消失，图标显示到通知栏呢？大家熟悉的FoxMail能做到，我们也可以做到。

VB代码VB小程序：在系统托盘为程序添加图标

VB代码VB小程序：在系统托盘为程序添加图标当前位置：首页> VB小程序1-99 > 在系统托盘为程序添加图标20. 在系统托盘为程序添加图标本人原创，转载请注明出处：/100bd/blog/item/330b4d88ab0fa0b80e244455.html为程序在系统托盘中添加图标，要解决两个问题：一、调用 API 函数 Shell_NotifyIcon 添加图标，设置正确的参数。

程序结束时，从系统托盘删除添加的图标。

二、拦截窗口的回调函数，响应用户在系统托盘图标上的鼠标事件，一般是弹出快捷菜单。

自定义的回调函数不能放在窗体代码中，必须在模块中。

编写有关窗口回调函数的程序，最大的难点在于调试。

调试时，如果在窗口回调函数过程的执行期间设置断点，轻则影响窗口的自动重画，重则使程序停止响应。

因此，修改代码后应注意及时保存。
