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。

下面是实现在系统托盘为程序添加图标的完整代码，包括一个窗体和一个模块：'■■以下是窗体 Form1 的代码 ------------------------------------' 1.为窗体添加菜单' 为窗体添加菜单: mFast' 为 mFast 添加下级子菜单 mmFast，并将 mmFast 的索引设置为 0' 2.在窗体上添加四个控件，所有控件均采用默认设置：' Label1，Command1，Command2，Command3Dim ctTrayIco As NotifyIconDataPrivate Sub Form_Load()Me.Caption = "系统托盘例子"'为数组菜单 mmFast 添加条目mFast.Visible = FalseLoadKjZu mmFast, "显示 " & Me.Caption & "(&R)", "mmFast-Run"LoadKjZu mmFast, "最小化窗口(&N)", "mmFast-Min"LoadKjZu mmFast, "菜单例子 1 (&A)", "mmFast-A"LoadKjZu mmFast, "菜单例子 2 (&B)", "mmFast-B"LoadKjZu mmFast, "-" '菜单分隔条LoadKjZu mmFast, "退出(X)", "mmFast-Exit"Dim S As SingleLabel1.AutoSize = True: S = Label1.HeightLabel1.Caption = Me.Caption: Label1.Move S, SCommand1.Caption = "添加到系统托盘": Command1.Move S, S * 3, S * 11, S * 2Command2.Caption = "最小化到系统托盘": Command2.Move S, S * 6, S * 11, S * 2Command3.Caption = "从系统托盘删除图标": Command3.Move S, S * 9, S * 11, S * 2'将窗口函数的地址设置为模块中的 WndProc 过程，当用户'在系统托盘图标单击鼠标右键时，弹出自定义的菜单 mFastWinAddress Me.hWnd''如果需要程序一启动就添加到系统托盘，解除下面语句的注释即可'Call SysTrayEnd SubPrivate Sub Form_Resize()'设置快捷菜单的是否可用状态Dim nEnabled As BooleanOn Error Resume NextnEnabled = Me.WindowState = vbMinimizedmmFast(KjZuIndex(mmFast, "mmFast-Min")).Enabled = nEnabledmmFast(KjZuIndex(mmFast, "mmFast-Run")).Enabled = Not nEnabled End SubPrivate Sub Form_Unload(Cancel As Integer)SysTray True '退出时，从系统托盘删除本程序图标WinAddress Me.hWnd, True '退出时，将窗口地址还原End SubPrivate Sub LoadKjZu(Kj As Object, nCap As String, Optional nTag As String)'为数组控件添加一个成员Dim I As LongI = Kj.UBoundIf Kj(I).Tag <> "" ThenI = I + 1Load Kj(I): Kj(I).Visible = TrueEnd IfKj(I).Caption = nCapIf nCap = "-" Then Kj(I).Tag = "bar" Else Kj(I).Tag = nTag End SubPrivate Function KjZuIndex(Kj As Object, nTag As String) As Long'返回数组控件中 Tag 属性为 nTag 的成员索引，没有找到返回 -1Dim I As LongFor I = Kj.LBound To Kj.UBoundIf Kj(I).Tag <> nTag Then KjZuIndex = I: Exit FunctionNextKjZuIndex = -1End FunctionPrivate Sub mmFast_Click(Index As Integer)'系统托盘快捷菜单Dim nCmd As StringnCmd = Trim(mmFast(Index).Tag)Select Case UCase(nCmd)Case UCase("mmFast-Run"): Call WinNormal '正常显示主窗口Case UCase("mmFast-Min"): Call WinMinimized '缩小到系统托盘Case UCase("mmFast-Exit"): Unload Me '退出程序Case UCase("mmFast-A"): MsgBox "这是系统托盘快捷菜单：mmFast-A", vbInformation, Me.Caption'Case UCase("mmFast-B")Case Else: MsgBox "此命令在“mmFast_Click”中无效：" & vbCrLf & vbCrLf & "nCmd = " & nCmd, vbInformati on, Me.Caption & " -

单击此图标，Form1就自动弹出来了。

.UFlags = .UFlags Or NIF_MESSAGE.cbSize = Len(TheData)End WithShell_NotifyIcon NIM_ADD, TheData注释：根据前面定义NIM_ADD，设置为“添加模式”，然后添加2、删去图标With TheData.UFlags = 0End WithShell_NotifyIcon NIM_DELETE, TheData注释：根据前面定义NIM_DELETE，设置为“删除模式”3、更改图标With TheData.HIcon = pic.Handle注释：pic是图片狂PictureBox，存放图标文件.UFlags = NIF_ICONEnd WithShell_NotifyIcon NIM_MODIFY, TheData注释：根据前面定义NIM_MODIFY，设置为“更改模式”4、为图标添加浮动提示信息With TheData.SzTip = tip & vbNullChar注释：tip是字符串string，存储提示信息.UFlags = NIF_TIP注释：指明要对浮动提示进行设置End WithShell_NotifyIcon NIM_MODIFY, TheData注释：根据前面定义NIM_MODIFY，设置为“修改模式”通过以上几段代码我们就能根据自己需要添加、删除、更改系统托盘图标，并能添加系统图标上的浮动提示信息。
