This thread is for discussions of XML SOAP.

Set objReq = Server.CreateObject("Microsoft.XMLDOM")
creates the object but for some reason objReq.SelectSingleNode says "Object Required"

changed above line to
Set objReq = Server.CreateObject("MSXML2.DOMDocument")
and everything  worked

Error in VB code. dblTax = objReturn.selectSingleNode(strQuery).Text
Return nothing becuase strQuery Xpath expression is case sensitive an its case doen not match whats been generated by ASP page . Eg return XML is "<soap.......
where as whats been checked in VB is <"SOAP............ A mismatch in Case

I am a beginner of SOAP & XML
I copy and save Soap.asp  to Win2000 Server wwwroot ,
then Copy Souce code of VB Client to run , but occure some error?

dblTax = objReturn.selectSingleNode(strQuery).Text

the strQuery is not correct format,what error?

I was wondering if someone could help me with my problem.  I am using code very similar to the XML Soap in my application and it communicates succesfully when used as a windows application and as an ASP.NET project but when I try and use the same method from my Windows Service I get the exception message QueryInterface for interface 'XMLHTTPRequest' has failed when I try to execute myobject.Open ...  The type of exception is an invalid cast exception even though the object was declared as new XMLHttpRequest.

Following suggestions from some web sites I put the line :
Threading.Thread.CurrentThread.ApartmentState = Threading.ApartmentState.STA

Apparently activex applications can't handle multi-threaded communication properly but this didn't stop my error from occurring.  The above line I placed in my On_start event and even tried in my New event with no success.  The time at which the XMLHttpRequest is fired off is after on_start in my timer_tick event.

Hi,

I Am New To SOAP Through VB. I am getting following error

" Method 'Send' Of 'IXMLHTTPRequest' Failed".

Error Number := -2146697211
.

I am sending you the code for consideration.

Option Explicit
  Dim objHTP As New MSXML.XMLHTTPRequest
  Dim strEnvelope As String
  Dim strreturn As String
  Dim objReturn As New MSXML.DOMDocument
  Dim dblTax As Double
  Dim strQuery As String
''Declaration Ends Here
Private Sub tax_cal()
'Create SOAP Envelope
strEnvelope = ""
strEnvelope = "<soap : envelope xmlns:soap=""urn:schemas-xmlsoap-org:soap.v1"">" & _
"<soap : header> </soap : header>" & _
"<soap : Body>" & _
"<m:getsalestax xmlns: m=""urn:myserver/soap:TaxCalculator"">" & _
"<salestotal>" & Val(txt_Sale.Text) & "<salestotal>" & _
"</m:getsalestax>" & _
"</Soap: Body>" & _
"</Soap: Envelope>"
'Setup To Post To Our Local Server
objHTP.open "post", "http://localhost/soap.asp", False
'Set A Standard SOAP / XML Header For The Content-Type
objHTP.setRequestHeader "Content-Type", "text/xml"
'Set A Header For The Method To Be Called
objHTP.setRequestHeader "SOAPMethodName", "urn:myserver/soap:Taxcalcultor#GetSalesTax"
'Make The SOAP Call
objHTP.send strEnvelope
'Get The Return Envelope
strreturn = objHTP.responseText
'Load The Return Envelope Into A DOM
objReturn.loadXML strreturn
'Query The Return Envelope
strQuery = "SOAP:Envelope/SOAP:Body/m:GetSalesTaxResponse/SalesTax"
dblTax = objReturn.selectSingleNode(strQuery).Text
txt_Tax.Text = dblTax
End Sub

I noticed that your code appears to have been written in VB6, if this is so then a possible cause of your issues is the declarations as new.  Try changing your as new statements to be just as classname and then before you use it say set myobject = new ServerXMLHTTPClass or whatever class you are creating.  VB6 handled the as new statement in a way which was not always reliable and this has caused me issues before.

Hi.
can u tell me how to fix the "dblTax = objReturn.selectSingleNode(strQuery).Text" error..pliz e.mail me

Hi all

to use this example with msxml 2.0 or higher
change

"msxml.xmlhttprequest"

to:

"msxml2.xmlhttp"
or
"msxml2.xmlhttp26"
or
"msxml2.xmlhttp30"
...
hth
bye

I copied all the code and followed all the instructions (including making sure the xml tags were all in the same case) and all I could get back from the soap request was ?????????????????????? etc etc with the odd † or - or = character thrown in.  2216 characters in all.  I'm using vb 6 and msxml4.
Any suggestions?  Did anyone get this to work?

Can any one help me to identify the references and dlls required to run this code.
I want to register the dlls required and then run this code in VB4.0.
I know i need msxml.dll and the other one is it mssoap1.dll ?
if thats the one where do i get it from?

thanks in advance.

if anyone knows the meaning of this, i could use the feedback.  my hunch is, that the SOAP server is not configured to handle the request properly.  but i dunno...  =)

Great work by ComponentSource and  they have very well explained VB 6.0 client and access to web service. I have a question here. How to monitor from where (mostly his/her web site URL not his/her machine IP) requester is consuming the web service? Techies, 'HTTP_REFERER' shows null  please, suggest any other possibilities.

Thanks

In .NET web services; How to monitor from where (mostly his/her web site URL but not his/her machine IP) requester is consuming the web service? Techies, 'HTTP_REFERER' and 'URLReferrer'  shows null  please, suggest any other possibilities.

I tried to copy the the code and add references to VB project and run the VB app. but get runtime error at the DOMDocument object accesing a single node.

Run time error 91.

MSXML2 and MTS Admin are the references I have added.


HELP!

Thanks ....
