用vb.net編寫項(xiàng)目移動(dòng)。。。求高人指點(diǎn)。。。。

窗體是指由兩個(gè)列表框（ListBox1、ListBox2）和4個(gè)命令按鈕（Button1“”按鈕，Button2“”按鈕，Button3“”按鈕，Button4“”按鈕）所構(gòu)成的界面，代碼：

VB.NET中標(biāo)準(zhǔn)的實(shí)體類怎么寫的,請(qǐng)教VB高手指導(dǎo)

'代碼來(lái)源：代碼街codejie.net

'由于在vb.net里變量名不區(qū)分大小寫（StuName和stuname是一樣的），所以個(gè)別變量名需要修改

'在vb.net中,模塊級(jí)變量的命名原則是以m_開頭

Public Class Student

Private m_stuNo As String '學(xué)生號(hào)字段

Private m_stuName As String '學(xué)生姓名字段

Private m_stuAge As Integer '學(xué)生年齡字段

Private m_stuAddress As String '學(xué)生住址字段

'無(wú)參構(gòu)造方法

Public Sub New()

End Sub

'有參構(gòu)造方法

Public Sub New(ByVal stuNo As String, ByVal stuName As String, ByVal stuAge As Integer, ByVal stuAddress As String)

m_stuNo = stuNo

m_stuName = stuName

m_stuAge = stuAge

m_stuAddress = stuAddress

End Sub

'學(xué)生號(hào)屬性

Public Property StuNo() As String

Get

Return m_stuNo

End Get

Set(ByVal value As String)

m_stuNo = value

End Set

End Property

'學(xué)生姓名屬性

Public Property StuName() As String

Get

Return m_stuName

End Get

Set(ByVal value As String)

m_stuName = value

End Set

End Property

'學(xué)生年齡屬性

Public Property StuAge() As Integer

vb.net 集成開發(fā)的三種模式

設(shè)計(jì)模式：界面設(shè)計(jì)和代碼編輯

運(yùn)行模式：運(yùn)行應(yīng)用程序

中斷模式：暫時(shí)中斷運(yùn)行，調(diào)試程序

怎么利用VB.NET實(shí)現(xiàn)三維繪圖

數(shù)學(xué)上不是有斜二測(cè)畫法，算好坐標(biāo)即可畫出

或者用AnyCAD的.Net圖形控件

也可以調(diào)用matlab 實(shí)現(xiàn)
