If you’re using Active Server Pages (ASP), you can use ByRef properties to find out what’s going on in your custom business object. Define a couple of variants in your ASP and send them ByRef to your business object. If you have an error in your object code, populate the fields with the err.number and err.description information. That way after the method calls, you can check the variable and display a message to the user.
<% Dim lErr, sErr Set MyObject = Server.CreateObject("MyProject.Cclass") MyObject.ReturnData lErr, sErr, sLocation if lErr = 0 then Session("FoundLocation") = True Else Response.Write "
" & sErr & "" end if%>
