我想实现MDI窗口的托盘，普通FORM托盘的代码不适合使用。
盼各位分享一下代码，跪谢（如有托盘闪烁的更好）

这种求助帖就那么不受人待见吗？

实现MDI窗口托盘的意思是右下角只出现子窗口图标，而父窗口图标不显示？
“不受人待见”可能是因为大家各有各的事干，也可能因为情况比较特殊，可能性太多了。
把鼠标移动代码改为
Private Sub MDIForm_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
其它不变
...
模块

Public 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
Public Const NIM_ADD = &H0
Public Const NIM_MODIFY = &H1
Public Const NIM_DELETE = &H2
Public Const WM_MOUSEMOVE = &H200
Public Const NIF_MESSAGE = &H1
Public Const NIF_ICON = &H2
Public Const NIF_TIP = &H4
Public Const WM_LBUTTONDBLCLK = &H203 'Double-click
Public Const WM_LBUTTONDOWN = &H201 'Button down
Public Const WM_LBUTTONUP = &H202 'Button up
Public Const WM_RBUTTONDBLCLK = &H206 'Double-click
Public Const WM_RBUTTONDOWN = &H204 'Button down
Public Const WM_RBUTTONUP = &H205 'Button up

Public Declare Function Shell_NotifyIcon Lib "shell32" Alias "Shell_NotifyIconA" (ByVal dwMessage As Long, pnid As NOTIFYICONDATA) As Boolean

MDI窗体

Dim nid As NOTIFYICONDATA ' trayicon variable

Sub minimize_to_tray()
Me.Hide
nid.cbSize = Len(nid)
nid.hwnd = Me.hwnd
nid.uId = vbNull
nid.uFlags = NIF_ICON Or NIF_TIP Or NIF_MESSAGE
nid.uCallBackMessage = WM_MOUSEMOVE
nid.hIcon = Me.Icon ' the icon will be your Form1 project icon
nid.szTip = "blablabla text u want to show when mouse over tray iicon" & vbNullChar
Shell_NotifyIcon NIM_ADD, nid
End Sub

Private Sub MDIForm_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
Dim msg As Long
Dim sFilter As String
msg = X / Screen.TwipsPerPixelX
Select Case msg
Case WM_LBUTTONDOWN
Me.Show ' show form
Shell_NotifyIcon NIM_DELETE, nid ' del tray icon
Case WM_LBUTTONUP
Case WM_LBUTTONDBLCLK
Case WM_RBUTTONDOWN
Case WM_RBUTTONUP
Me.Show
Shell_NotifyIcon NIM_DELETE, nid
Case WM_RBUTTONDBLCLK
End Select

End Sub

Private Sub MDIForm_Unload(Cancel As Integer)
Shell_NotifyIcon NIM_DELETE, nid ' del tray icon
End Sub

Private Sub minimize_Click()
minimize_to_tray
End Sub

自己按需修改调整

多谢，我马上去试下
另外，下面这段，用RESIZE判断的话效果有没有区别？

我调整了之后放入，同时加入了托盘的右键菜单：显示窗口和退出
但是显示窗口点击时要点击两次才能反应，这是什么原因？

Dim nid As NOTIFYICONDATA ' trayicon variable
Sub minimize_to_tray()
Me.Hide
nid.cbSize = Len(nid)
nid.hwnd = Me.hwnd
nid.uId = vbNull
nid.uFlags = NIF_ICON Or NIF_TIP Or NIF_MESSAGE
nid.uCallBackMessage = WM_MOUSEMOVE
nid.hIcon = Me.Icon ' the icon will be your Form1 project icon
nid.szTip = "处理平台" & vbNullChar
Shell_NotifyIcon NIM_ADD, nid
End Sub
Private Sub MDIForm_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
Dim msg As Long
Dim sFilter As String
msg = X / Screen.TwipsPerPixelX
Select Case msg
Case WM_LBUTTONDOWN
Case WM_LBUTTONUP
Case WM_LBUTTONDBLCLK
Case WM_RBUTTONDOWN
Case WM_RBUTTONUP
  Me.PopupMenu Pomenu
Case WM_RBUTTONDBLCLK
End Select

End Sub
Private Sub MDIForm_Resize()
  If Me.WindowState = vbMinimized Then
    minimize_to_tray
  Else
    Shell_NotifyIcon NIM_DELETE, nid
  End If
End Sub

Private Sub MDIForm_Unload(Cancel As Integer)
Shell_NotifyIcon NIM_DELETE, nid ' del tray icon
End Sub
Private Sub MDIForm_Load()
Shell_NotifyIcon NIM_DELETE, nid ' del tray icon
End Sub

Private Sub MDIForm_QueryUnload(Cancel As Integer, UnloadMode As Integer)
Shell_NotifyIcon NIM_DELETE, nid ' del tray icon
Unload Me
End Sub

Private Sub showw_click()
  Me.Show
  Me.WindowState = vbNormal
End Sub
Private Sub quitp_click()
Unload Me
End Sub

定义一个变量
Dim MiniStatus As Boolean

Sub minimize_to_tray()
...
MiniStatus = True
End Sub

Private Sub maxmize_Click()
...
MiniStatus = False
End Sub

Private Sub MDIForm_Resize()
  If Me.WindowState = vbMinimized And MiniStatus = False Then
    minimize_to_tray
...
End Sub

OK，解决。
能说明一下原因么？

又有个问题出现。我在未最小化时用鼠标在窗口内部晃动一下，结果出现菜单了
毫无解决头绪，求助。

出现菜单是执行popupmenu?检查一下为什么会执行到这一句

就是下面这部分语句，而且我试过了，无论Me.PopupMenu Pomenu放到哪个条件，晃动鼠标还是会出现菜单
Select Case msg
Case WM_LBUTTONDOWN
Case WM_LBUTTONUP
Case WM_LBUTTONDBLCLK
Case WM_RBUTTONDOWN
Case WM_RBUTTONUP
  Me.PopupMenu Pomenu
Case WM_RBUTTONDBLCLK
End Select
