现在的问题是：可以点放小 缩放到托盘区，但不能还原。 有大侠能解决一下吗？

Const NIF_ICON = &H2

Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
If Button = 1 And Me.WindowState = 1 Then
Me.WindowState = 0 '程序回复到Normal状态
Me.Visible = True '从任务栏中清除图标
Call Shell_NotifyIcon(NIM_DELETE, nfIconData) '退出图标
End If
End Sub
应该是把那个MouseMove改成MouseDown单击应该可恢复了，你的代码好像在哪见过？
那么在上述过程中加一条语句
ShowWindow Me.hwnd,SW_RESTORE
试试
