VB6.0。当程序在托盘运行时，怎样弹出消息？

当程序在托盘运行时，怎样弹出消息？（如图是某软件实现的效果）
大家不要介意我的托盘，空的只不过是我把它擦掉了。

Answer 1

新建一个模块
粘上以下代码

' Update the tray icon.
With ni

Shell_NotifyIcon NIM_MODIFY, ni
TrayInfo = ni.szTip
End Function

调用的方法如下：
TrayBalloon Form1, "当前状态:" & "导入数据完成" & "", App.Title, NIIF_INFO Or NIIF_NOSOUND

Answer 2

我有一个托盘控件，留下你的邮箱，我把控件发给你 

代码

Private Sub Command1_Click()

With EFMTrayIcon1

.Visible = True

.TimeOut = 0

.PopupBalloon Me, "你好!", "提示"

End With

End Sub

Private Sub Form_Load()

EFMTrayIcon1.Visible = True

End Sub

Private Sub Form_Unload(Cancel As Integer)

EFMTrayIcon1.Visible = False

End Sub

Answer 3

是不是在托盘被隐藏了？点击托盘-自定义-找到vb6.0设置显示图标和通知。另外可能是你装的vb有问题。

追问

不是隐藏，我是说怎么弹出消息！空的只不过是我把它擦掉了。

追答

能说明白一点吗？

追问

就是我的程序放到托盘里面之后想要提示用户时间，我只会用MsgBox，但假如用MsgBox就太直接了，摆在屏幕中间，用户还得点“确定”，我想问的就是怎样实现图中弹出的消息（就是系统默认的，不要自建窗体）。

追答

这个不知道，不好意思。

Answer 4

新增一个窗体FORM2用于放提示信息,定好位置
在原窗体上放一个Timer1,设置1秒中断一次:Tag = "0"
并加上下面的代码
Private Sub Timer1_Timer()
Tag = (Val(Tag) + 1) Mod 5
If Tag = "0" Then Form2.Show
If Tag = "1" Then Form2.Hide
End Sub

追问

忘了说了，不要新增窗体。
