You can use the XMLHTTP object which comes with MSXML, (see http://support.microsoft.com/default.aspx?kbid=290591) or if you prefer an OCX, try the Internet Transfer Control.

Surely its not that difficult to translate that little bit of js:
function XMLHTTPButton_onclick() {
    var DataToSend = "id=1";
    var xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
    xmlhttp.Open("POST","http://<%=Request.ServerVariables("Server_Name")%>/Receiver.asp",false);
    xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
    xmlhttp.send(DataToSend);
    alert(xmlhttp.responseXML.xml);
}

delete all trailing ;
var -> Dim
new ActiveXObject -> CreateObject
put Call in front of the next 3 lines
alert -> MsgBox

voila!

now the code i have tried is as follows but, it gives the statusText as 'Bad Request'. if print the responseXML.xml also it gives "". any problem in my code , please help

    Dim xmlhttp
    Set xmlhttp = New MSXML2.ServerXMLHTTP
    xmlhttp.Open "POST", "http://localhost:8080/logini.jsp", False
    xmlhttp.setRequestHeader "Content-Type", "application/x-www-form- urlencoded"
    xmlhttp.send DataToSend
    lblStatus.Caption = xmlhttp.statusText
    'lblStatus.Caption = xmlhttp.responseXML.xml
    Set xmlhttp = Nothing

<base href="http://localhost:8080/logini.jsp">
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML//EN">
<HTML>

  <HEAD>

  </HEAD>

  <BODY BGCOLOR="#eeeeff">

1. use the "XMLHTTP" object from VB, not the "ServerXMLHTTP" object
2. do you really have a space here "application/x-www-form- urlencoded"?
3. is there anything in "DataToSend" variable
4. have you looked at the webserver logs to see what the request looks like from that end? this may give additional clues.

Have you tried a GET instead of a POST? Are you actually POSTing anything?

ratheeshpkr · October 18th, 2004, 07:29 AM

i am really sorry. by using GET i am getting the correct result.
can i send data by POST in the same way ie

dataToSend="login=" & txtUserName & "&passwd=" & txtPassword

this way i am sending data in GET method
is it work

Thanks for your valuable inforamtions......
