vb.net连接cad vbnet odbc

vb.net打开cad画图的问题?

你去查查书吧,书上挺详细的,在这说不好说,你先在项目里引用。然后 Dim acadapp As AcadApplication Dim acaddoc As AcadDocument On Error Resume Next AcadApp = GetObject(, "AutoCAD.Application") If Err.Number Then Err.Clear() AcadApp = CreateObject("AutoCAD.Application") If Err.Number Then MsgBox("不能运行AutoCAD,请检查是否安装了AutoCAD") Exit Sub End If End If AcadApp.Visible = True '界面可视

VB.NET连接AutoCAD出错

这个是vb.net教材里面的吧,我也是前两天刚下的。遇到类似的问题,下面是我的解决办法

首先要参考引用Autodesk.AutoCAD.Interop.dll还有Autodesk.AutoCAD.Interop.Common.dll

然后代码有两处也需要相应修改,我用的是.NET 的 vb2008

'Dim AcadApp As AutoCAD.AcadApplication

Dim AcadApp As Autodesk.AutoCAD.Interop.AcadApplication

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Call 连接AutoCAD()

End Sub

Sub 连接AutoCAD()

On Error Resume Next

AcadApp = GetObject(, "AutoCAD.Application")

If Err.Number Then

Err.Clear()

AcadApp = CreateObject("AutoCAD.Application")

If Err.Number Then

MsgBox("不能运行AutoCAD,请检查是否安装了AutoCAD")

Exit Sub

End If

End If

AcadApp.Visible = True '界面可视

'AcadApp.WindowState = AutoCAD.AcWindowState.acMax '界面最大化

AcadApp.WindowState = Autodesk.AutoCAD.Interop.Common.AcWindowState.acMax

AppActivate(AcadApp.Caption) '显示AutoCAD界面

End Sub
