在ASP应用程序中使用DLL时出错

Question

我开始研究一个项目，该项目显示了我在下面用线描述的错误：

' 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

如何解决这些问题？

Answer 1

如果通过“它返回一个xml”，你的意思是PerformTxn方法返回一个XML对象，如MSXML2 DOMDocument或Element，那么你就错过了Set语句： -

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