VB最小化程序

VB怎样输入代码,按控制按钮就自动最小化到任务栏
追问:好多错误哦。不过我找出原因了,
答案:在Form中制作一个菜单,在窗体上点右键-菜单编辑器,标题随便,名称“F00”(不含引号,下同),去掉“可见”前的勾,“下一个”,标题“打开”,名称“F01”,点“右箭头”,“下一个”,标题退出,名称“F02”,点“右箭头”,“确定” 

以下是代码,效果是程序运行时不显示在托盘中图标,点最小化后显示在托盘图标并且不在任务栏中显示窗口,双击图标打开窗口,右键点图标弹出菜单


'-----------------------窗体中--------------------------
Dim WindowTop, WindowLeft

Function WindowStyle()
'以下把程序放入System Tray====================================System Tray Begin
With 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 = "已最小化到托盘" & vbNullChar
.cbSize = Len(nfIconData)
End With
Call Shell_NotifyIcon(NIM_ADD, nfIconData)
'=============================================================System Tray End
Me.Hide
End Function

Private Sub Form_Resize()
WindowTop = Me.Top
WindowLeft = Me.Left
If Me.WindowState = 1 Then
WindowStyle
End If
End Sub

Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
Dim lMsg As Single
lMsg = X / Screen.TwipsPerPixelX
Select Case lMsg
Case WM_LBUTTONDBLCLK '双击左键显示窗体,要改成其他的看模块里的定义
ShowWindow Me.hWnd, SW_RESTORE
Me.Top = WindowTop
Me.Left = WindowLeft
'Call Shell_NotifyIcon(NIM_DELETE, nfIconData)
Me.SetFocus
Case WM_RBUTTONUP '在托盘图标上点右键显示菜单
PopupMenu F00 '菜单名称为F00,做菜单时你可以改成别的,这里也得改成相应的
End Select
End Sub

Private Sub F01_Click()
ShowWindow Me.hWnd, SW_RESTORE
Me.Top = WindowTop
Me.Left = WindowLeft
Call Shell_NotifyIcon(NIM_DELETE, nfIconData)
End Sub

Private Sub F02_Click()
Call Shell_NotifyIcon(NIM_DELETE, nfIconData)
End
End Sub

Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer)
'退出程序时删除托盘图标
Call Shell_NotifyIcon(NIM_DELETE, nfIconData)
End Sub


'-----------------------模块中--------------------------
'在系统托盘显示图标的模块

Option Explicit
Public Const MAX_TOOLTIP As Integer = 64
Public Const NIF_ICON = &H2
Public Const NIF_MESSAGE = &H1
Public Const NIF_TIP = &H4
Public Const NIM_ADD = &H0
Public Const NIM_DELETE = &H2

Public Const SW_RESTORE = 9
Public Const SW_HIDE = 0
Public nfIconData As NOTIFYICONDATA
Public Type NOTIFYICONDATA
cbSize As Long
hWnd As Long
uID As Long

End Type
Public Declare Function ShowWindow Lib "user32" (ByVal hWnd As Long, ByVal nCmdShow As Long) As Long
Public Declare Function Shell_NotifyIcon Lib "shell32.dll" Alias "Shell_NotifyIconA" (ByVal dwMessage As Long, lpData As NOTIFYICONDATA) As LongPrivate Sub Command1_Click()
Form1.WindowState = 1
End Sub

窗体加一个按钮 command1 添加一下代码:

 

Private Sub Command1_Click()
Me.WindowState = vbMinimized
End Sub

Private Declare Function Shell_NotifyIcon Lib "shell32.dll" (ByVal dwMessage As Long, lpData As NOTIFYICONDATA) As Long
Const NIM_ADD = &H0
Const NIM_DELETE = &H2
Const NIF_ICON = &H2
Const NIF_MESSAGE = &H1
Const NIF_TIP = &H4
Const WM_MOUSEMOVE = &H200
Const WM_LBUTTONDBLCLK = &H203
Private Type NOTIFYICONDATA
cbSize As Long
hWnd As Long
uId As Long
uFlags As Long
uCallBackMessage As Long
hIcon As Long
szTip As String * 64
End Type
Dim tray As NOTIFYICONDATA
Private Sub Command1_Click()
tray.cbSize = Len(tray)
tray.uId = vbNull
tray.hWnd = Me.hWnd
tray.uFlags = NIF_TIP Or NIF_MESSAGE Or NIF_ICON
tray.uCallBackMessage = WM_MOUSEMOVE
tray.hIcon = Me.Icon
tray.szTip = "测试" & vbNullChar
Shell_NotifyIcon NIM_ADD, tray
Me.Hide
End Sub
Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
Dim msg As Long
msg = X / 15
If msg = WM_LBUTTONDBLCLK Then
Me.Show
Shell_NotifyIcon NIM_DELETE, tray
End If
End Sub

这就是托盘全代码 自己试试     记到给分哈

你想要工程的话邮我  5 4 6 7 3 6 8 7 5
