楼主：flion1985这个人我不认得，但他抄了我的答案，只是加几个注解就说是他答的了，你要为我做主啊。

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

Private Type NOTIFYICONDATA
cbSize As Long
hwnd As Long
uID As Long
uFlags As Long
uCallbackMessage As Long
hIcon As Long
szTip As String * MAX_TOOLTIP
End Type

Private Declare Function Shell_NotifyIcon Lib "shell32.dll" Alias "Shell_NotifyIconA" _
(ByVal dwMessage As Long, lpData As NOTIFYICONDATA) As Long
Private nfIconData As NOTIFYICONDATA

nfIconData.hwnd = Me.hwnd
nfIconData.uID = Me.Icon
nfIconData.uFlags = NIF_ICON Or NIF_MESSAGE Or NIF_TIP
nfIconData.uCallbackMessage = WM_MOUSEMOVE
nfIconData.hIcon = Me.Icon.Handle
nfIconData.szTip = "这是托盘图标" & vbNullChar
nfIconData.cbSize = Len(nfIconData)
Call Shell_NotifyIcon(NIM_ADD, nfIconData)

Call Shell_NotifyIcon(NIM_DELETE, nfIconData)
你试验一下，不行在找我。
