VB编写托盘图标实例
VB编写托盘图标有两个要点，一是使用 Shell_NotifyIcon 函数显示图标；二是向系统注册 TaskbarCreated 消息，以便explorer崩溃时恢复托盘的图标。
首先需要增加一个模块文件，内容如下：
Public Declare Function Shell_NotifyIcon Lib "shell32.dll" Alias "Shell_NotifyIconA" (ByVal dwMessage As Long, lpData As NOTIFYICONDATA) As Long
Public nfIconData As NOTIFYICONDATA
Public Const MAX_TOOLTIP As Integer = 64
' uFlags to NOTIFYICONDATA structure
Public Const NIF_MESSAGE = &H1
Public Const NIF_ICON = &H2
Public Const NIF_TIP = &H4
Public Const NIF_STATE = &H8
Public Const NIF_INFO = &H10
' dwMessage to Shell_NotifyIcon
Public Const NIM_ADD = &H0
Public Const NIM_MODIFY = &H1
Public Const NIM_DELETE = &H2
Public Const NIM_SETFOCUS = &H3
Public Const NIM_SETVERSION = &H4
Public Const WM_MOUSEMOVE = &H200 '当鼠标指针移至图标上
Public Const WM_LBUTTONDOWN = &H201 '鼠标左键按下
Public Const WM_LBUTTONUP = &H202 '鼠标左键弹起
Public Const WM_LBUTTONDBLCLK = &H203
Public Const WM_RBUTTONDOWN = &H204 '鼠标右键按下
Public Const WM_RBUTTONUP = &H205 '鼠标右键弹起
Public Const WM_RBUTTONDBLCLK = &H206
Public Const SW_RESTORE = 9
Public Const SW_HIDE = 0
Public Type NOTIFYICONDATA
cbSize As Long ' 结构大小(字节)
hwnd As Long ' 处理消息的窗口的句柄
uId As Long ' 唯一的标识符
uFlags As Long ' Flags
uCallBackMessage As Long ' 处理消息的窗口接收的消息
hIcon As Long ' 托盘图标句柄
szTip As String * 128 ' Tooltip 提示文本
dwState As Long ' 托盘图标状态
dwStateMask As Long ' 状态掩码
szInfo As String * 256 ' 气球提示文本
uTimeoutOrVersion As Long ' 气球提示消失时间或版本
' uTimeout - 气球提示消失时间(单位:ms, 10000 -- 30000)
' uVersion - 版本(0 for V4,

1.用Microsoft Internet Transfer Control 控件（在部件中添加），代码非常简单，如下（在form上添加一个Inet1和Text1和Command1）：
Private Sub Command1_Click()
Text1.Text = Inet1.OpenURL("http://www.vbgood.com/")
End Sub
2.如果是使用 W ......
Option Explicit
Private Declare Function GetSystemMenu Lib "user32" (ByVal hWnd As Long, ByVal bRevert As Long) As Long
Private Declare Function DeleteMenu Lib "user32" (ByVal hMenu As Long, ByVal nPosition As Long, Optional ByVal wFlags As Long = 0&) As Long
Private Declare Function DrawMenu ......
