VB.NET编写托盘程序

编写托盘程序
编写托盘程序
托盘程序作为一类特殊的窗体，其快捷图标显示在系统托盘中，窗体本身则隐藏不可见。

在.NET之前版本的VB中编写托盘程序是十分困难的，但是提供的新的NotifyIcon组件却使VB初学者也能轻松编写一个这样的程序：
新建“Windows应用程序”，设置主窗体Opacity属性为0，FormBorderStyle属性为None，ShowInTaskbar属性为False，这样窗体将在启动后隐藏。

在窗体上放置一个NotifyIcon组件NotifyIcon1，一个ContextMenu（弹出菜单）组件 ContextMenu1，并根据需要为ContextMenu1添加菜单项。

设置NotifyIcon1的ICON属性，这个图标就是应用程序出现在系统托盘中的快捷图标；设置NotifyIcon1的Text属性为“ 托盘程序”，这就是鼠标移动到托盘图标时弹出的文字说明；设置NotifyIcon1的ContextMenu属性为ContextMenu1，也就是右键单击快捷图标时的弹出菜单为 ContextMenu1。

OK，按F5运行！
几乎不用编写代码，一个托盘程序就这样轻松实现了。

VB教程网/VBjc/Vb.HTM编写趣味撞球小游戏文章来源：沐风经典文章作者：佚名Visual Basic是一个功能强大的工具，它有一大特点就是易学易用，下面我们就通过写一个“趣味撞球”的程序来初步体会一下。

首先启动VB5，新建一个标准的EXE工程。

此时可以看到，工程包括一个Form1框体。

在Form1边框的右下角按住鼠标左键不放，拖动鼠标把Form1的面积改为适当大小，比如6930×4320。

再在属性框中把Form1的ScaleMode 属性改为3－Pixel，表明我们将以像素为我们的坐标计算单位，把Form1的StartUpPosition 属性设为2－CenterScreen，使运行时窗体出现在屏幕正中。

现在，在控件面板上选取CommandButton（命令按钮）控件，为Form1添加Command1和Command2两个按钮控件，把它们的大小设为121×25，再在属性框中把Command1的Caption填为“＆GO”，把Command2的Caption填为“＆QUIT”，并把Command1放到框体的右上角，把Command2放到框体的右下角。

然后，在控件面板上选取Timer（时钟）控件，为Form1添加一个Timer1时钟控件。

再在属性框中把它的Enabled属性改为False，Interval属性改为50，前一个值表示该时钟控件是否激活，后一个值决定该时钟控件产生Timer事件的间隔时间，我们将用它来控制小球的移动频率。

到此为止，我们已经完成了全部的界面设计工作。

接下来要做的全部工作就是填入程序代码了。

Dim BallX As IntegerDim BallY As IntegerDim AddX As IntegerDim AddY As IntegerDim HitX As IntegerDim W As IntegerDim H As IntegerPrivate Sub Command1_Click()BallX=Int(Rnd(1)＊Form1.ScaleWidth/10)＊5＋25BallY=Int((Form1.ScaleHeight)/10)＊5AddX=－5AddY=－5Form_PaintTimer1.Enabled=TrueEnd SubPrivate Sub Command2_Click()EndEnd SubPrivate Sub Form_MouseMove(Button As Integer,Shift As Integer,X As Single,Y As Single) X=X－50If X<15 Then X=15If X>W－105 Then X=W－105HitX=XIf Timer1.Enabled=True ThenLine(16,H－5)－(W－6,H),＆HC0C0C0,BF Line(HitX,H)－(HitX＋100,H－5),0,BF End IfEnd SubPrivate Sub Form_Paint()ClsW=Int((ScaleWidth－140)/5)＊5H=Int((ScaleHeight－10)/5)＊5 BackColor=＆HC0C0C0Line(10,10)－(15,H),0,BFLine(W－5,10)－(W,H),0,BFLine(10,10)－(W,15),0,BFEnd SubPrivate Sub Timer1_Timer()Form1.Circle(BallX,BallY),4,＆HC0C0C0 BallX=BallX＋AddXBallY=BallY＋AddYForm1.Circle(BallX,BallY),4,0If BallX<=20 Then AddX=－AddXIf BallY<=20 Then AddY=－AddYIf BallX>=W－10 Then AddX=－AddXIf BallY>=H－10 ThenIf BallXHitX＋100 ThenTimer1.Enabled=FalseForm_PaintEnd IfAddY=－AddYEnd IfEnd Sub一旦程序代码输入完毕，你就可以按F5开始执行它，或是在File菜单里选取Make来生成EXE执行文件了，瞧，小球已经在你的屏幕上蹦来蹦去了。

vb系统托盘资料

VB托盘程序详解很多软件运行时会在系统托盘区(就是桌面右下角显示时间的区域)出现一个小图标，它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的状态。

本例就给出了一个功能比较完整的托盘程序，我们可以看到怎样用API函数Shell_NotifyIcon来添加、删除、更改托盘图标；而且例中还演示了为托盘图标添加右键菜单和浮动提示的方法。

程序(附后)用到了Shell_NotifyIcon、SendMessage、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(taskbar status area)的图标，所以我们先来看看这个函数的声明和参数：使用API函数之前必须先在程序中声明如下：Declare Function Shell_NotifyIcon Lib "shell32.dll" Alias "Shell_NotifyIconA"(ByVal dwMessage As Long, lpData As NOTIFYICONDATA) As Long其中各参数的意义如下表:参数：意义dwMessage 为消息设置值，它可以是以下的几个常数值：0、1、2NIM_ADD = 0 加入图标到系统状态栏中NIM_MODIFY = 1 修改系统状态栏中的图标NIM_DELETE = 2 删除系统状态栏中的图标LpData 用以传入NOTIFYICONDATA数据结构变量，其结构如下所示：Type NOTIFYICONDATAcbSize As Long 需填入NOTIFYICONDATA数据结构的长度 HWnd As Long 设置成窗口的句柄Uid As Long 为图标所设置的ID值UFlags As Long 设置uCallbackMessage,hIcon,szTip是否有效UCallbackMessage As Long 消息编号HIcon As Long 显示在状态栏上的图标SzTip As String * 64 提示信息End Type返回值 Long，非零表示成功，零表示失败在使用这个API函数之前我们应该先定义结构类型NOTIFYICONDATA：Public Type NOTIFYICONDATAcbSize As Long HWnd As LongUid As Long UFlags As LongUCallbackMessage As LongHIcon As LongSzTip As String * 64End Type然后定义一个NOTIFYICONDATA的变量TheData来记录设置托盘图标的数据Private TheData As NOTIFYICONDATA这时我们就可以使用这个函数来设置系统托盘图标了，具体方法如下：1、添加图标With TheData.Uid = 0.HWnd = frm.HWnd 'frm.HWnd是程序主窗体的句柄.cbSize = Len(TheData).HIcon = frm.Icon.Handle 'frm.Icon.Handle指向主窗体的图标.UFlags = NIF_ICON.UCallbackMessage = TRAY_CALLBACK'作用是允许返回消息，在下一节中会有详细解释。

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。

VB中控件拖放操作的教学研究

ＶＢ中控件拖放操作的教学研究在VB教学中，拖放操作是一个难点内容。

本文介绍在教学过程中如何讲解通过修改拖放坐标和使用API函数，实现在不同容器之间拖放控件的操作，并给出了实例程序。

关键词：VB；拖放；坐标；API函数在Visual Basic应用程序中，为了实现更加灵活的用户控制，时常需要由用户自己安排一些控件的位置。

在Windows操作系统中，经常使用拖动操作移动或复制文件；在一些应用程序中，可将工具栏中的控件按钮拖放到文档窗口中，实现插入对象操作；在Office软件中，还可以随意定制工具栏中的按钮。

在我多年的VB一线教学实践中，发现拖放操作的讲解难点在于拖放的目标位置设置。

在拖放控件时，根据源位置和目标位置的容器控件不同分为两种情况：在同一容器对象中拖放控件，在不同容器对象中拖放控件。

学生对于在不同容器中拖放控件有很多疑问，因此我在教学中采用了由浅入深、循序渐进的方法，分别讲解这两种情况的处理方法，并通过典型的实例让学生掌握拖放操作的相关概念和实现方法，收到了不错的效果，学生感觉比较容易理解，下面具体介绍一下这两种情况拖放操作的实现方法。

1在同一容器内部拖放控件在教学过程中，我首先讲解拖放操作的相关概念，然后举例介绍与拖放操作相关的属性、方法和事件。

拖放（Drag）操作是指在窗体中，将鼠标指针指向控件，按住鼠标按键移动鼠标，到达目标位置后松开鼠标按键，被拖放的控件移动到目标位置[1]。

在同一容器中拖放控件比较容易实现，可以通过设置控件的拖放属性，或调用控件的Drag方法来实现。

在教学过程中以命令按钮（CommandButton）控件为例，在窗体上添加一个命令按钮Command1，设置DragMode属性为1-Automatic （自动拖放），运行程序后用鼠标左键拖动命令按钮，可以看到拖动时显示灰色控件边框，但控件并不真正移动到目标位置。

若设置DragMode属性为0-Manual （手动拖放），则需要编写命令按钮的MouseDown事件调用其Drag方法，事件过程的代码如下：Private Sub Command1_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)Command1.Drag 1 …开始拖动控件End Sub运行程序时演示拖放操作，让学生看到两种设置方法的效果相同，使学生了解DragMode属性的含义和Drag方法的用法。

vb实现托盘(含程序)

VB托盘我按照下面的方法建了一个VB程序，可是在我自己的电脑上可以托盘，但换了电脑在别人的电脑上运行就没有托盘了，怎么回事啊！1、新建立一个VB6工程，将Form1的ShowInTaskBar属性设置为False2、菜单：工程--添加模块按“打开”这样就添加了一个新模块，名为Module1,保存为Module1.bas3、在Module1中写下如下代码：Option ExplicitPublic Const MAX_TOOLTIP As Integer = 64Public Const NIF_ICON = &H2Public Const NIF_MESSAGE = &H1Public Const NIF_TIP = &H4Public Const NIM_ADD = &H0Public Const NIM_DELETE = &H2Public Const WM_MOUSEMOVE = &H200Public Const WM_LBUTTONDOWN = &H201Public Const WM_LBUTTONUP = &H202Public Const WM_LBUTTONDBLCLK = &H203Public Const WM_RBUTTONDOWN = &H204Public Const WM_RBUTTONUP = &H205Public Const WM_RBUTTONDBLCLK = &H206Public Const SW_RESTORE = 9Public Const SW_HIDE = 0Public nfIconData As NOTIFYICONDATAPublic Type NOTIFYICONDATAcbSize As LonghWnd As LonguID As LonguFlags As LonguCallbackMessage As LonghIcon As LongszTip As String * MAX_TOOLTIPEnd TypePublic Declare Function ShowWindow Lib "user32" (ByVal hWnd As Long, ByVal nCmdShow As Long) As LongPublic Declare Function Shell_NotifyIcon Lib "shell32.dll" Alias "Shell_NotifyIconA" (ByVal dwMessage As Long, lpData As NOTIFYICONDATA) As Long'4、在Form1的Load事件中写下如下代码：Private Sub Form_Load()'以下把程序放入System Tray====================================System Tray BeginWith nfIconData.hWnd = Me.hWnd.uID = Me.Icon.uFlags = NIF_ICON Or NIF_MESSAGE Or NIF_TIP.uCallbackMessage = WM_MOUSEMOVE.hIcon = Me.Icon.Handle'定义鼠标移动到托盘上时显示的Tip.szTip = App.Title + "(版本" & App.Major & "." & App.Minor & "." & App.Revision & ")" & vbNullChar.cbSize = Len(nfIconData)End WithCall Shell_NotifyIcon(NIM_ADD, nfIconData)'=============================================================System Tray EndMe.HideEnd Sub'5、在Form1的QueryUnload事件中写入如下代码：Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer)Call Shell_NotifyIcon(NIM_DELETE, nfIconData)End Sub'6、在Form1的MouseMove事件中写下如下代码：Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)Dim lMsg As SinglelMsg = X / Screen.TwipsPerPixelXSelect Case lMsgCase WM_LBUTTONUP'MsgBox "请用鼠标右键点击图标!", vbInformation, "实时播音专家"'单击左键，显示窗体ShowWindow Me.hWnd, SW_RESTORE'下面两句的目的是把窗口显示在窗口最顶层'Me.Show'Me.SetFocus'' Case WM_RBUTTONUP'' PopupMenu MenuTray '如果是在系统Tray图标上点右键，则弹出菜单MenuTray'' Case WM_MOUSEMOVE'' Case WM_LBUTTONDOWN'' Case WM_LBUTTONDBLCLK'' Case WM_RBUTTONDOWN'' Case WM_RBUTTONDBLCLK'' Case ElseEnd SelectEnd Sub7、现在将程序保存起来运行看看系统托盘处是否增加了一个本工程的图标。

托盘程序

静态托盘程序的编写过程往NotifyIcon实例中添加菜单，首先要创建ContextMenu实例，此实例主要作用是表示快捷菜单，其中的菜单项是通过创建MenuItem实例来实现，托盘程序中的菜单有几个菜单项，就创建几个MenuItem实例。

然后把这些菜单项加入到ContextMenu实例，并把此实例赋值给NotifyIcon实例的ContextMenu属性，这样托盘程序右键点击弹出的菜单就完成了。

下面是具体代码：创建ContextMenu实例和MenuItem实例：FriendWithEventsContextMenu1 As System.Windows.Forms.ContextMenu FriendWithEventsMenuItem1 As System.Windows.Forms.MenuItem FriendWithEventsMenuItem2 As System.Windows.Forms.MenuItem FriendWithEventsMenuItem3 As System.Windows.Forms.MenuItem把这些菜单项加入到ContextMenu实例，并把ContextMenu实例赋值给NotifyIcon实例的ContextMenu属性：Me.MenuItem1=NewSystem.Windows.Forms.MenuItem()Me.MenuItem2=NewSystem.Windows.Forms.MenuItem()Me.MenuItem3=NewSystem.Windows.Forms.MenuItem()Me.NotifyIcon1.ContextMenu=Me.ContextMenu1Me.NotifyIcon1.Text="的托盘程序"Me.NotifyIcon1.Visible=True'设定托盘程序托盘区位置显示图标Me.NotifyIcon1.Icon=TrayIcon'在ContextMenu实例中加入菜单项Me.ContextMenu1.MenuItems.Add(Me.MenuItem1)Me.ContextMenu1.MenuItems.Add(Me.MenuItem2)Me.ContextMenu1.MenuItems.Add(Me.MenuItem3)Me.MenuItem1.Index=0Me.MenuItem1.Text="显示窗体"Me.MenuItem2.Index=1Me.MenuItem2.Text="隐藏窗体"Me.MenuItem3.Index=2Me.MenuItem3.Text="退出"当把ContextMenu实例赋值给NotifyIcon实例的ContextMenu属性后，托盘程序的缺省状态是当鼠标右击托盘图标，就会弹出对应的菜单。

VB实现托盘完整代码

VB托盘完整代码'VB最小化到托盘（含托盘菜单）的方法很多，这里介绍的是最简洁的做法，使用cSysTray控件，该控件需要自己编译并添加。

'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。

），使用安装包安装的用户，可在VB安装包里找到。

'以下是代码'API发送按键函数。

Private Declare Sub keybd_event Lib "user32" (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long) Const KEYEVENTF_KEYUP = &H2’托盘菜单-退出选项'tuichu 为一菜单的名称'此处用API函数发送ALT+F1指令调用窗体退出菜单，因此窗体菜单-退出选项需设置快捷键ALT+F1Private Sub tuichu_Click()cSysTray1.InTray = False主程序.WindowState = vbNormal主程序.Visible = True主程序.SetFocuskeybd_event vbKeyControl, 0, 0, 0keybd_event vbKeyF1, 0, 0, 0keybd_event vbKeyControl, 0, KEYEVENTF_KEYUP, 0End sub'托盘弹出菜单Private Sub cSysTray1_MouseDown(Button As Integer, Id As Long)If Button = 2 Then PopupMenu tuopan, 10End Sub'最小化后归托盘Private Sub Form_Resize()If Me.WindowState = vbMinimized ThencSysTray1.InTray = TrueMe.Visible = FalseElse: cSysTray1.InTray = TrueEnd If'托盘菜单弹出主界面'zhujiemian 为一菜单项的名称Private Sub zhujiemian_Click()主程序.WindowState = vbNormal主程序.Visible = TrueEnd Sub'双击托盘菜单弹出主界面Private Sub cSysTray1_MouseDblClick(Button As Integer, Id As Long)主程序.WindowState = vbNormal主程序.Visible = True主程序.SetFocusEnd Sub'单击关闭不退出程序Private Sub Form_Unload(Cancel As Integer)主程序.HideCancel = FalseEnd Sub'单击关闭不退出程序Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer) Cancel = 1主程序.HideEnd Sub’tui为窗体菜单-退出选项名称Private Sub tui_Click()’快捷键设ALT+F1EndEnd Sub'注："主程序"代表一个窗体(Form)，窗体菜单-退出选项需设置快捷键ALT+F1 '这个控件有一个小小的问题，如果托盘菜单有退出选项，不能直接用"End 语句"，否则在编译后运行期间用户选择退出后，操作系统会报错，以上使用发送按键方法避免出错，当然还有其他避免出错方法。

【摘要】Windows 95、Windows 98、Windows NT等操作系统的界面上都增加了Shell层的技术,这就为广大编程人员开辟了界面编程的新途径。

本文讲述的是如何用VB 5.0来编写托盘程序。

托盘程序主要解决两个问题:(1)创建、修改、删除托盘;(2)如何对托盘接收到的消息进行处理。

这就要用到几个Win32 API。

首先,Shell_NotifyIcon是用于托盘的Shell API。

该API用到一个NOTIFYICONDATA结构,该结构包括:hIcon(托盘图标指针)。

托盘程序详解(一)
很多软件运行时会在系统托盘区(就是桌面右下角显示时间的区域)出现一个小图标，它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的状态。本例就给出了一个功能比较完整的托盘程序，我们可以看到怎样用API函数Shell_NotifyIcon来添加、删除、更改托盘图标；而且例中还演示了为托盘图标添加右键菜单和浮动提示的方法。
