** 在VB.NET中去掉了Line控件，我们用.NET转换包含有Line控件的VB6的工程后，发现取而代之的是Label。 **
** 其实我们还可以有另一种画线的方法： **
Public Class Line
Inherits System.Windows.Forms.UserControl
Public TopLC As System.Drawing.Color = System.Drawing.Color.White '上线颜色
Public FootLC As System.Drawing.Color = System.Drawing.Color.Black '下线颜色
Public LineT As Type '直线类型
Public Enum Type
Tf '凸
Ft '凹
Flat '平面
End Enum
#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
'UserControl 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

'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。
