需要说明的是Shell_NotifyIcon这个api，微软自带的api浏览器下写的是错的
Public Declare Function Shell_NotifyIcon Lib "shell32.dll" Alias _
" Shell_NotifyIconA" (ByVal dwMessage As Long, lpData As NOTIFYICONDATA) As Long
" Shell_NotifyIconA" 多加了一个空格
调用的时候
Private Sub Form_Load()
AddIcon Picture1, "hello world..."
Me.Hide
App.TaskVisible = False
End Sub
Private Sub Picture1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
If Hex(X) = "1E3C" Then
Me.PopupMenu file
End If
End Sub
file是菜单，这个很简单自己随便写一个就成了，别忘了写个end退出
