关于vb.net调试网页的信息

vbnet如何在调试时如何选择英文界面

它会根据操作系统自动选择语言。

VB.NET实现多语言(根据操作系统自动选择语言)系统,可以实现中文,日文,英文界面,实现了多界面操作。

英语（English）是印欧语系-日耳曼语族下的语言，由26个字母组成，是欧盟以及许多国际组织以及英联邦国家的官方语言，亦是世界上使用最广泛的语言。它诞生于日德兰半岛和莱茵河流域，通过英国的殖民活动传播到了世界各地，后因英美两国经济、军事和政治的世界领先地位而成为一种国际语言。

VB.NET 向指定(网页或软件)的输入框内输入字符,如何实现?

假如Form1有个TextBox1，双击TextBox1填入123

Public Class Form1

Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Integer, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Integer

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

End Sub

Private Sub TextBox1_DoubleClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.DoubleClick

System.Windows.Forms.SendKeys.Send("123")

End Sub

End Class

看你的VB.NET 版本了

用 My.Computer.Keyboard.SendKeys("123", True) 代替 System.Windows.Forms.SendKeys.Send("123") 也可以

原码：

Public Class Form1

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

End Sub

Private Sub TextBox1_DoubleClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.DoubleClick

My.Computer.Keyboard.SendKeys("123", True)

End Sub

End Class

VB.NET,完整并调试程序

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim a() As Integer = {678, 45, 324, 528, 439, 387, 87, 875, 273, 823}

Dim i%, j%, n%, t%, k%

Label1.Text = ""

n = UBound(a)

For i = 0 To n - 1

For j = 0 To n - i - 1

If a(j) a(j + 1) Then

t = a(j)

a(j) = a(j + 1)

a(j + 1) = t

End If

Next j

For k = 0 To n - 1

Label1.Text = a(k) " "

Label1.Text = vbCrLf

Next i

End Sub

这是正确代码我已经调试过了。尽请放心

用vb.net做的校友录……（附所有源代码）

来源：不详作者佚名点击数：31 录入时间：07-12-17 15:21:39

想必大家都上过校友录吧，里面的功能虽然不是很强大，但是为我们这些毕业之后各奔西东的学子来说，到真是提供了一个好的聚集点，下面是我用vb.net做的校友录，当然也不能说是校友录了，只能说是我们班的学友录了：）不过只要你掌握了这种编程思想，校友录就不在话下了。这里我将重点谈一下关于管理员权限赋予。

以前有这个想法的时候，难就难在管理员身份的赋予上，开始想如果一般用户在被提升为管理员之后，我可以把他的信息转到另外一个表中，以后登陆的时候先检查manage表中是否有他就行了，这种办法我已经实现了，是不是有些笨……可是正在我要正式开工的时候，一个想法突然冒了出来，是什么呢？呵呵，就是在数据库中再增加一个字段了如果是第一次注册就让这个字段item(int)的值为0，要是被提升之后就update为1，班级创始人呢？当然了，在他申请时付给他一个班级id，然后先判断班级id为这个已经注册的人信息条数是否为0，如果是，那么就付给他item=2好了。下面的代码中，我没有实现这个功能，因为我做的是班友录的，当然了，我就是管理员喽：）

在这里，我使用的是checkboxlist(两个)，一个用来转换数据（visibe=fause），一个用来显示数据，还有一个checkbox用来写全部选中的事件。当然了还有两个按钮事件，一个是用来提升为管理员的，一个是用来降级为一般用户的，这两个按钮在判断为一般用户时

enable都是为fause的，只有当判断登录为管理员时才为true。当然了，如果你是班级创始人，是不可能被降级的：）

这里用来显示信息的我用的是一个datagrid，当判断为非管理员时，删除栏的visible将为fause，为管理员的时候，才为true，也就是说只有管理员才可以删除信息。而不是注册的用户是不能发言的所有的按钮控件的enable将都为fause。

代码如下：board.aspx

当然了，这里面还有好多不足的地方，恳求高手批评指正。

校友录还有一些其它的功能就很简单了，这里就不再探讨了。

vb.net 2008 怎样进入调试模式？怎样逐语句运行？怎样添加监视？

在VB环境中执行源代码，本身就是调试模式

按F8即可逐语句运行

点击语句左端空白处，将其背景色变为深红，就是添加断点，运行到该语句会停下来

可以在变量、对象等语句上点击右键，选择“添加监视”即可

VB.net2008调试运行时，界面与我设计中的界面有点不一样，请问是什么问题，如何解决？

我的理解应该是几个控件容器(如groupbox)不在同一层导致,在容器控件dock属性设置不是NONE时常会出现这样的问题,你可以在"布局"工具栏中把容器全设置成顶层,或用"文档大纲"查看各层的先后顺序.

控件容器大小有可能变化时,可以设置其中一个dock属性为fill

总之,设计时综合使用层与dock属性.
