passing complex data types with vbscript?
gr...@apba.net
use complex data types for both incoming data and return data. We are
attempting to help another group access this web service from
vbscript/ASP. Is this possible? I have found a few posts scattered
around the internet saying complex data types aren't possible with
vbscript.
Is this true? Can I manually create my XML document in the vbscript,
pass it to the web service, then manually deconstruct the return XML?
Thanks,
Greg

The following uses JavaScript to call the web service, but the same exact
steps would apply for VBScript. You can concatenate a string, or you can
use the DOM model (more information at
http://support.microsoft.com/kb/893659/).
The following is an HTML file, no ASP.NET or anything involved here (nothing
but client code).

x.setRequestHeader("Content-Type", "text/xml; charset=utf-8");

x.send(envelope);
alert(x.responseText);

Probably a perfect example given by Kirk.
My 2cents...
You may want to look into the topic of XML Serialization and custom
attributes in case you have a really complex structure of data possibly with
arrays.

service, so I'm glad you included that in your example.
It looks like I will need to construct my SOAP message and body
manually, which is fine.
Thanks for the tip on XML Serialization, I'll look into that also.
