相当于visual studio 2012 vb.net中的getobjectcontext()？

Question

我有一个vb6 COM对象,我正在转换为VB.Net 2012

我的示例代码如下所示:

Dim ObjContext ,objx ,objy As Object

Dim Rs As ADODB.Recordset

Set ObjContext = GetObjectContext

Set objx =ObjContext.CreateInstance("abc.class1")

Set Objy = ObjContext.CreateInstance("abcde.class2")


Set Rs = objx.getvalue(query)

 If Rs.EOF And Rs.BOF Then

      ObjContext.SetAbort
        Set objx = Nothing
        Set ObjContext = Nothing
        Set Objy = Nothing

  End If

VB 2012中GetObjectContext()和createinstance()的等价物是什么？

我怎样才能从.net中删除这个概念？

试试这个：
我想你想要这个

Dim ObjContext ,objx ,objy As Object

Dim Rs As ADODB.Recordset

Set ObjContext = GetObjectContext

Dim ObjContext As COMSVCSLib.ObjectContext

Dim objAppServer As New COMSVCSLib.AppServer

ObjContext = objAppServer.GetObjectContext()

Set objx =ObjContext.CreateInstance("abc.class1")

Set Objy = ObjContext.CreateInstance("abcde.class2")


Set Rs = objx.getvalue(query)

 If Rs.EOF And Rs.BOF Then

      ObjContext.SetAbort
        Set objx = Nothing
        Set ObjContext = Nothing
        Set Objy = Nothing

  End If
