Hi, I am trying to pass an number from a classic asp webpage to a .NET
webservice.
Because my C# webservice expects an integer and classic ASP uses
variants I keep getting problems with object casts;
In my asp page I have the following code which works fine
HTTP.Open "GET","http ://myserver/myService.asmx/LogPerson?ID=10 0",
False
*IF* I do the following I get an error from the .NET webservice
"System.Argumen tException: Cannot convert to System.Int32. Parameter
name: type ---System.FormatEx ception: Input string was not in a
correct format"
Dim PersonID
PersonID=100
HTTP.Open "GET","http ://myserver/myService.asmx/LogPerson?ID=" &
PersonID, False
==========
My signature in the webservice is simply
[WebMethod]
public bool LogPerson(int PersonID)
{
/// some code
return true;
}
I have tried changing my signature to
public bool LogPerson(objec t PersonID)
and then casting etc but I keep getting casting errors
Any help appreciated
Thanks in advance

Hello,
If you wan't to read a web service from an asp.net page, you need to format
a soap request, it isn't possible to get an answer with a simple http call.
this is a good way to do it : http://www.eggheadcafe.com/articles/20011103.asp

That's not how web services work. Web services are not simple AJAX, they
are SOAP-encoded calls.
On the client, you need to create a POST request, and the request's body
must be compliant with SOAP. SOAP is a XML dialect, which encodes a
remote method call.
If you really want to do that, you need to study SOAP and create a
correctly encoded request. That's a lot of work (I did it for
JavaScript, and it needs a lot of study before getting it to work).
Nowadays, SOAP clients use proxy-generating code to make using web
services easier (.NET with Web references, JavaScript with ATLAS, etc...).
In your case, for something simple as that, I would recommend abandoning
web services and using a ASHX generic HTTP handler on .NET. Then it's
much, much easier to send GET requests to it. The ASHX handler can
return plain text, plain old XML, or whatever you can place into a Response.

Thanks for your help everyone.
In the end I just loaded the returned XML into an DOMObject
Set HTTP = CreateObject("M SXML2.XMLHTTP")
Set xmlDOC =CreateObject(" MSXML.DOMDocume nt")
HTTP.Open ...
xmlDOC.load(HTT P.responseXML)
and parsed the DOM object and it works a treat
again, thanks

How can you pass an entire XML Document to a webservice (do you do this with
a SOAP envelope body?). Say a supplier sends or posts the entire updated
product & price list to your webservice.
Also, how to access or "grab" the Document within the webmethod? Is it just
a parameter?
I'm also concerned with the size limitations for the XML being passed
Any documentation on this that would be great.
