Hello

i have a problem with classic asp page requests an asp.net web service

no exception triggered but no result appeared

I'm calling a method from the service "Process"

accepts string parameter called path

and returns nothing
my asp page code is:

<html>
<head>
<title>Calling a webservice from classic ASP</title>
</head>
<body>
<%
If Request.ServerVariables("REQUEST_METHOD") = "POST" Then
  Dim xmlhttp
  Dim DataToSend
  DataToSend="path="&Request.Form("text1")
  Dim postUrl
  postUrl = "http://..Server../service.asmx/Process"
  Set xmlhttp = server.Createobject("MSXML2.XMLHTTP")
  xmlhttp.Open "POST",postUrl,false
  xmlhttp.setRequestHeader "Content-Type", _
      "application/x-www-form-urlencoded"
  xmlhttp.send DataToSend
  Response.Write(xmlhttp.responseText)
End If
%>
<FORM method=POST name="form1">
Enter Values to be Added<br>
<INPUT type="text" value="String value to be send" name="text1">
<br><br>
<INPUT type="submit" value="Add" name="submit1">
</form>
</body>
</html>
</br></br></br>

also i tried the code with an asp.net page

<br />
MyService ss = new MyService();<br />
ss.Process(TextBox1.Text);<br />

and that worked correctly

please someone help what's wrong with it ?

VB

xmlhttp.send DataToSend
Response.Write(xmlhttp.responseText)

I'm not an expert in old-school ASP, but that looks suspect to me. I would expect the call to be asynchronous, so you are attempting to write out the response before you've received it. A better bet would be to use jQuery to call the site for you. I have an article here[^] that demonstrates how to do this in jQuery.
