vb点虐 动态添加 vb动态添加控件并绑定事件

我知道在VB和VB点虐 中怎样添加动态控件，可是我添加的这些控件怎样添加相应的事件呢？

Dim Text() As Object

在网站设计制作、成都网站制作过程中，需要针对客户的行业特点、产品特性、目标受众和市场情况进行定位分析，以确定网站的风格、色彩、版式、交互等方面的设计方向。创新互联建站还需要根据客户的需求进行功能模块的开发和设计，包括内容管理、前台展示、用户权限管理、数据统计和安全保护等功能。

Private Sub Form_Load()

Dim i As Integer

Dim nTop As Long

ReDim Text(1 To 10)

For i = 1 To 10

Set Text(i) = Controls.Add("VB.TextBox", "Text1" CStr(i))

Text(i).Height = 300

Text(i).Top = nTop

Text(i).Visible = True

nTop = nTop + 30 * 15

Next i

End Sub

添加动态控件。你可以自己试试看。 form1上什么都不加运行这个程序后会发现自动生成了10个text控件

VB.NET 用二维数组的方式动态加控制 例如在窗体上动态添加GroupBox，然后再在GroupBox里动态添加控件

下面这段代码完成，在窗体上用语句添加2个 GroupBox控件，且在每个GroupBox控件中添加4个 RadioButton 控件。

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

Dim i As Integer

'添加2个GroupBox

Dim MyGroupBox(2) As GroupBox

For i = 1 To 2

'将一个GroupBox控件加入到Form上

MyGroupBox(i) = New GroupBox

Me.Controls.Add(MyGroupBox(i))

'设置该GroupBox控件的属性

MyGroupBox(i).Height = 240

MyGroupBox(i).Width = 600

MyGroupBox(i).Top = (i - 1) * (240 + 20) + 20

MyGroupBox(i).Left = 20

'修改新加入控件的Text值

MyGroupBox(i).Text = "GroupBox" CStr(i)

Next

'每个GroupBox中添加4个单选按钮

Dim MyRadioButton1(4) As RadioButton

Dim MyRadioButton2(4) As RadioButton

For i = 1 To 4

MyRadioButton1(i) = New RadioButton

Me.Controls.Add(MyRadioButton1(i))

MyRadioButton1(i).Parent = MyGroupBox(1)

'设置该GroupBox控件的属性

MyRadioButton1(i).Height = 20

MyRadioButton1(i).Width = 120

MyRadioButton1(i).Top = (i - 1) * (20 + 20) + 40

MyRadioButton1(i).Left = 20

'修改新加入控件的Text值

MyRadioButton1(i).Text = "RadioButton1_" CStr(i)

Next

For i = 1 To 4

MyRadioButton2(i) = New RadioButton

Me.Controls.Add(MyRadioButton2(i))

MyRadioButton2(i).Parent = MyGroupBox(2)

'设置该GroupBox控件的属性

MyRadioButton2(i).Height = 20

MyRadioButton2(i).Width = 120

MyRadioButton2(i).Top = (i - 1) * (20 + 20) + 40

MyRadioButton2(i).Left = 20

'修改新加入控件的Text值

MyRadioButton2(i).Text = "RadioButton2_" CStr(i)

Next

End Sub

如何在vb点虐 里面动态添加控件

Private WithEvents NewTextBox As TextBox

'通过使用WithEvents关键字声明一个对象变量为新的命令按钮

Private Sub Command1_Click()

If NewTextBox Is Nothing Then

Set NewTextBox = Controls.Add("VB.TextBox", "cmdNew", Form1)

NewTextBox.Move 200, 200

NewTextBox.Width = Form1.Width - 450

NewTextBox.Height = Form1.Height - 1400

NewTextBox.Visible = True

End If

End Sub

Private Sub Command2_Click()

If NewTextBox Is Nothing Then

Exit Sub

Else

Controls.Remove NewTextBox

Set NewTextBox = Nothing

End If

End Sub

vb点虐 动态添加多个控件只能显示第一个？

你只有一个catcon，所以不行，你必须定义数组catcon()才可以显示多个
