錯誤而在ASP應用程序中使用DLL

Question

我開始一個項目，該項目顯示了我在下面描述與行的錯誤工作：

' VBScript 
Set lLogOn = Server.CreateObject("RuleEngine26.Transact") 
' They have a DLL named RuleEngine26.dll and are creating object out of it 
' They put functions like dbconnection inside of it 
' There is no source code for it, only the DLL is available 

' VBScript 
lprofile = lLogOn.PerformTxn(lChnlId, lAppId,"SignOn","",lUserId,lxmlrequest) 
' Here they are calling a function and it returns XML 
' The expected XML should contain 4 child nodes but I am getting none back 

如何解決這些問題？

Answer 1

如果「它返回一個XML」你的意思是PerformTxn方法返回一個XML對象，如MSXML2 DOM文檔或元素，那麼你缺少一個Set聲明： -

Set lprofile = lLogOn.PerformTxn(lChnlId, lAppId,"SignOn","",lUserId,lxmlrequest)
