David Thomas Using PocketSOAP to call the SOAP API from VBScript/VB6
I'm after a recent working example (code) that I can prototype in VBScript and then pass onto my client, who needs to make a targeted change to a legacy VB6 app to make a real-time query against a Contact record in Salesforce. The query is currently against a SQL DB that is not part of the legacy app, but will be migrated to salesforce.com.
The code I'm using (below), fails on when trying to parse the response (e.parse t)
--> Error during parsing, no element found at line 1
--> Code: 80044240, PocketSOAP.Envelope.11:
This article (https://developer.salesforce.com/forums/ForumsMain?id=906F00000008rMBIAY) from 2004 with replies from the PocketSOAP creator @Superfell is useful, but doesn't quite have a full example.

One followup question ... do you recommend I use the Enterprise WSDL, or is the Partner WSDL also fine? Any gotchas I should be aware of?
(I did get the Partner WSDL working by changing the endpoint and namespace, and got a slightly different return result format.)
A good tip for readers on Windows 7 is to make sure you use the 32-bit version of cscript, i.e. c:\windows\syswow64\cscript.exe, to avoid automation errors.
Initially the script failed with the same Automation error, but I'd been running 64-bit cscript and hacking the registry to configure thunking (http://www.gfi.com/blog/32bit-object-64bit-environment/). As I only did the CoClasses in the CreateObject statements, I suspect I may have missed some dependent classes that were causing the failure.
Now that I have the VBS version working (no corporate firewall), I'll move onto the VB6 case from behind the firewall and introduce the proxy.
Nice coffee pic btw -- reminds me of my favourite roaster Campos here in Sydney. Let's do coffee if you're in town any time, my shout.
{urn:fault.partner.soap.sforce.com}UNSUPPORTED_CLIENT : UNSUPPORTED_CLIENT: TLS 1.0 has been disabled in this organization. Please use TLS 1.1 or higher when connecting to Salesforce using https.
Do we need to update the component? Highly appreciate your help.
