ASP Classic XML GW Connection to ASP.NET

[Martin Hansen]

I have this code:
----------------------------
function funcLogin(orderType)
username = request.Form("username")
password = request.Form("password")
myxml = "<?xml version='1.0' ?>"
myxml = myxml & "<function>"
myxml = myxml & "<getlogin>"
myxml = myxml & "<username>" & username & "</username>"
myxml = myxml & "<password>" & password & "</password>"
myxml = myxml & "</getlogin>"
myxml = myxml & "</function>"
funcLogin = myxml
end function

set objXMLHttp = server.createobject("MSXML2.ServerXMLHTTP.3.0")
set objDOMDocument = server.createobject("MSXML2.DOMDocument.3.0")

dim requestXML

requestXML = funcLogin(OrderType)

objXMLHttp.Open "POST", "http://192.168.2.54/receive.asp", False
objDOMDocument.loadXML requestXML
objXMLHttp.Send objDomdocument

set objDOMDocumentResponse = server.createobject("MSXML2.DOMDocument.3.0")
objDOMDocumentResponse.loadXML objXMLHttp.responseText
-----------------

I need to write it, so it works in ASP.NET 3.5 (VB).

Someone who has an idea of what i'm doing wrong?

First off, using string concatenation in any year/technology is a horrible
way to create Xml.

........

Second....for something like this..you want to look at the XmlWriter class.

See
http://msdn2.microsoft.com/en-us/library/4d1k42hb(VS.71).aspx

as you migrate the code to dotnet, please don't repeat the string concat
mistake.

(I learned this the hard way too, so I'm not dogging you, just trying to
help).

......

Third.
Are you shipping hte xml off to a POST method?
See
http://samples.gotdotnet.com/quicks...s/clientPOST.src&file=CS\clientpost.cs&font=3
or
http://groups.google.com/group/microsoft.public.dotnet.framework.aspnet/msg/5d13224a77b89add


...

But please, abandon the string concatenation practice.

Hi Martin,

From your description, I understand you're using a classic ASP page to send
XMLHTTP request to an ASP.NET Web page(with some data in XML format) and
you found it not work, correct?

As for the problem, I'd like to confirm some further things:

**What's the detailed error you've got (if the response return, you can
check the response content to see what's the error at application level)

**For the ASP.NET page side, is the ASP.NET page developed by you and also
controlled by you? Or do you have the permission to modify it?

If you have control over the server-side page(or modify it), I suggest you
change the ASP.NET page to an httphander. This is because for HTTP POST
request, ASP.NET page will check the viewstate info, this is different from
other server document tech(such as classic asp, jsp, ....). Therefore, you
may need to provide the Viewstate info in your request also. See the
following article which mentioned this:

#Screen Scraping, ViewState, and Authentication using ASP.Net
http://odetocode.com/Articles/162.aspx

If you use httphandler, there is no viewstate checking.
