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
Private Function isopen() As AutoCAD.AcadApplication
Try
dim CADapp_temp AutoCAD.AcadApplication = GetObject(, "AutoCAD.Application"运氏)
return CADapp_temp
Catch ex As Exception
Return Nothing
End Try
End Function
'调用上面的旁稿散函数,如果敬亩为nothing表示没有打开，否则打开并返回对象
