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
怎样用vb.net2008读写注册表?
（1）添加项
Dim reg As RegistryKey
reg = Registry.CurrentUser
reg = reg.OpenSubKey("Software\Microsoft\Internet Explorer\Main", True)
reg.SetValue("Window Title", Me.TextBox1.Text)
（2）读取项
Dim reg As RegistryKey
Dim regStr As String
reg = Registry.CurrentUser
reg = reg.OpenSubKey("Software\Microsoft\Internet Explorer\Main", True)
regStr = reg.GetValue("Window Title")
Me.TextBox1.Text = regStr
（3）删除项
Dim reg As RegistryKey
reg = Registry.CurrentUser
reg = reg.OpenSubKey("Software\Microsoft\Internet Explorer\Main", True)
reg.DeleteValue("Window Title")
VB.net 2008如何写用户控件？
参考：

#Region "变量"
Dim Down_Color As Color = Color.Blue
Dim UP_Color As Color = Color.Gray
Dim Mode As Short = 0
Dim flag As Boolean
Dim offset_X As Integer
Dim offset_Y As Integer
Dim Mouse_P As Point
#End Region
#Region "属性"
'按下颜色
Public Property _DownColor As Color
Get
Return Down_Color
End Get
Set(ByVal value As Color)
Down_Color = value
End Set
End Property
'弹起颜色
Public Property _UpColor As Color
Get
Return UP_Color
End Get
Set(ByVal value As Color)
UP_Color = value
End Set
End Property
'滑动模式 0-横 1-竖
Public Property _Mode As Short
Get
Return Mode
End Get
Set(ByVal value As Short)
Mode = value
End Set
End Property
#End Region
Private Sub UserControl1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Me.BackColor = UP_Color
End Sub
'鼠标按下
Private Sub UserControl1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseDown
Me.BackColor = Down_Color
Mouse_P = e.Location
flag = True
End Sub
'鼠标移动
Private Sub UserControl1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseMove
If flag = False Then Exit Sub
Select Case Mode
Case 0 '横向·
offset_X = e.X - Mouse_P.X
If Me.Location.X + offset_X + Me.Width = Me.ParentForm.Width Or Me.Location.X + offset_X = 0 Then
flag = False
Else
Me.Location = New Point(Me.Location.X + offset_X, Me.Location.Y)
End If
Case 1 '竖向·
offset_Y = e.Y - Mouse_P.Y
If Me.Location.Y + offset_Y + Me.Height + 30 = Me.ParentForm.Height Or Me.Location.Y + offset_Y = 0 Then
flag = False
Else
Me.Location = New Point(Me.Location.X, Me.Location.Y + offset_Y)
End If
End Select
End Sub
'鼠标弹起
Private Sub UserControl1_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseUp
Me.BackColor = UP_Color
