vb.net程序执行时候发生算术运算中发生溢出或下溢，求求解决

[newyhj]

按F5运行提示如下
未处理的“System.ArithmeticException”类型的异常出现在 system.drawing.dll 中。

其他信息: 算术运算中发生溢出或下溢。

代码如下：
Public Class Form1
Inherits System.Windows.Forms.Form

#Region " Windows 窗体设计器生成的代码 "

Public Sub New()
MyBase.New()

'该调用是 Windows 窗体设计器所必需的。
InitializeComponent()

'在 InitializeComponent() 调用之后添加任何初始化

End Sub

'窗体重写 dispose 以清理组件列表。
Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
If disposing Then
If Not (components Is Nothing) Then
components.Dispose()
End If
End If
MyBase.Dispose(disposing)
End Sub

'Windows 窗体设计器所必需的
Private components As System.ComponentModel.IContainer

'注意: 以下过程是 Windows 窗体设计器所必需的
'可以使用 Windows 窗体设计器修改此过程。
'不要使用代码编辑器修改它。
Friend WithEvents Button1 As System.Windows.Forms.Button
Friend WithEvents Button2 As System.Windows.Forms.Button
Friend WithEvents TextBox As System.Windows.Forms.TextBox
<System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent()
Me.Button1 = New System.Windows.Forms.Button
Me.Button2 = New System.Windows.Forms.Button
**** Me.TextBox = New System.Windows.Forms.TextBox ***
Me.SuspendLayout()
'
'Button1
'
Me.Button1.Location = New System.Drawing.Point(32, 176)
Me.Button1.Name = "Button1"
Me.Button1.TabIndex = 0
Me.Button1.Text = "演示"
'
'Button2
'
Me.Button2.Location = New System.Drawing.Point(184, 176)
Me.Button2.Name = "Button2"
Me.Button2.TabIndex = 1
Me.Button2.Text = "退出"
'
'TextBox
'
Me.TextBox.Location = New System.Drawing.Point(56, 24)
Me.TextBox.Multiline = True
Me.TextBox.Name = "TextBox"
Me.TextBox.Size = New System.Drawing.Size(184, 104)
Me.TextBox.TabIndex = 2
Me.TextBox.Text = "TextBox1"
'
'Form1
'
Me.AutoScaleBaseSize = New System.Drawing.Size(6, 14)
Me.ClientSize = New System.Drawing.Size(292, 273)
Me.Controls.Add(Me.TextBox)
Me.Controls.Add(Me.Button2)
Me.Controls.Add(Me.Button1)
Me.Name = "Form1"
Me.Text = "welcome"
Me.ResumeLayout(False)

End Sub

#End Region

Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Text = "欢迎使用VB.NET开发工具"
TextBox.Text = "欢迎使用VB.NET开发工具"

End Sub

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

End Sub

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
End
End Sub
End Class

我编的很多程序以前都能运行。现在莫名其妙的都不能不能运行了，错误提示一样，重装VS也不行
有时候连空FORM也不行运行。上面打*号部分为中断部分。
给分是不多，但希望大家能帮我解决啊

你的强类命名肯定不行呀，与基类冲突
TextBox文本框的名称改为TextBox1就行了

Friend WithEvents TextBox As System.Windows.Forms.TextBox
Me.TextBox = New System.Windows.Forms.TextBox
↓↓↓↓↓↓↓↓改为

Friend WithEvents TextBox1 As System.Windows.Forms.TextBox
Me.TextBox1 = New System.Windows.Forms.TextBox

下面也一样改

同意楼上的朋友!

应该还有其他代码吗，应该是数值类型的溢出。

在98下面水晶报表也有此问题。

我改过来了还是不行啊。
问题还是一样呢。。。
