VB.Net读取AutoCAD图纸
如果可以的话请把分给我
以下是cad2007版的，引用autocad 2007 type library 和autocad/objectdbx common 17如果是04或者版本更低的只要引用autocad 2007 type library，代码的话大同小异，思路是一样的
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
On Error Resume Next
Dim acadapp As Autodesk.AutoCAD.Interop.AcadApplication
acadapp = GetObject(vbNullString, "autoCAD.application")
Dim acaddoc As Autodesk.AutoCAD.Interop.AcadDocument
acaddoc = acadapp.ActiveDocument
Dim Ms As Autodesk.AutoCAD.Interop.Common.AcadModelSpace
Ms = acaddoc.ModelSpace
Dim acadObjectI As Autodesk.AutoCAD.Interop.Common.AcadObject
Dim Linei As Autodesk.AutoCAD.Interop.Common.AcadLine
Dim Circlei As Autodesk.AutoCAD.Interop.Common.AcadCircle
Dim Polylinei As Autodesk.AutoCAD.Interop.Common.AcadPolyline
Dim pt As Autodesk.AutoCAD.Interop.Common.AcadPoint
For Each acadObjectI In Ms
Debug.Print(acadObjectI.ObjectName)
Select Case acadObjectI.ObjectName
Case "AcDbLine"
Linei = acadObjectI
Debug.Print("X =" Linei.StartPoint(0).ToString)
Debug.Print("Y =" Linei.StartPoint(1).ToString)
Case ""
Case ""
End Select
Next
End Sub
求vb.net的源代码，最好说明其解决问题，越多越好，满意加50分。
下面这段代码，是我用来计算每个月存500元进银行，连续30年，最后连本带利能有多少钱。这里面涉及复利计算。界面中右边的文本框用来输出每一次计算的结果。
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim nianxian As Integer '年限变量
Dim dingcun As Integer '定存变量
Dim fuli_big As Long '大复利
Dim fuli_small As Long '小复利
Dim i As Integer '循环变量
Dim DATAstring As String '数据字符串
nianxian = Val(年限_TextBox.Text)
dingcun = Val(定存_TextBox.Text)
DATAstring = ""
For i = 1 To nianxian
fuli_small = dingcun * (1 + 0.1875)
dingcun = fuli_small
fuli_big = fuli_big + fuli_small
DATAstring = DATAstring + "[" + Trim(Str(i)) + "]" + Str(fuli_big) + Chr(13) + Chr(10)
'DATAstring = DATAstring + "[" + Trim(Str(i)) + "]" + Str(fuli_small) + Chr(13) + Chr(10)
Next
'fuli_big = fuli_small
TextBox1.Text = DATAstring
结果_TextBox.Text = Str(fuli_big) + "元"
End Sub
