This question is related to an earlier one that I posted. But the issue has been boiled down to its simpliest parts. I am sorry for posting to SoPW twice today about this, but I could use some help understanding this.

I've been working with rchiav and have produced a DLL and two ASPs with the following code.

VB ActiveX DLL 

Public Function CopyString(ByRef strTo, ByVal strFrom)

  strTo = strFrom
  
End Function

[download]

VB ASP 

<%@ Language='VBScript' %>

<%
  Dim strTo
  Dim strFrom
      strFrom = "This is my test string"

  Dim objDLLTest
  Set objDLLTest = Server.CreateObject("myTest.myClass")
  objDLLTest.CopyString strTo, strFrom
%>

<%=strTo%>

[download]

PerlScript ASP 

<%@ Language='PerlScript' %>

<%
  my $to;
  my $from = "This is my test string";

  my $DLLObject = $Server->CreateObject("myTest.myClass");
  $DLLObject->CreateBarChart($to, $from);
%>

<%=$to?"It is set":"It is not set"%><br>
<%=$to%>

[download]

The VB ASP result reads "This is my test string". The PerlScript ASP reads "It is not set".

How do I pass and return strings from a VB DLL?
