I have a test program that is using a .dll i created. it works find when i access it form the program, like so:

Dim IE As HTMLParser.IE
Set IE = CreateObject("HTMLParser.IE")

txtResults.Text = IE.GetRequest(testvalue, testvalue)

This works find and puts the results in a textbox. Now, when I try to use the .dll from a webpage using jscript, i get the error "Object variable or With block variable not set" using the code below..

var IE = Server.CreateObject("HTMLParser.IE");
var result = IE.GetRequest(testvalue,testvalue);

what the heck am i doing wrong?

I think you should use the statement like this to create an object from the class in JScript(or JavaScript):

var var_name = new class_name;

wish it were that simple. i think it has something to do with MTS and running dll's in a transaction. I'm finding this is not so easy to do with PWS. i let you know if i ever get this thing working.

Take a look at this code. It is a changed version of my .asp page, which creates object from dll written by me.
It seems to work in general: creates object with javascript.
I commented vbscript statements to show the differences in declarations and usage of object variable:


<%@language=javascript%>
<html>
<head>
<title>Untitled</title>

</head>

<body>
<%
var stu;
stu = new ActiveXObject(&quot;Student.clsStudent&quot;);
var blnResult = false;
//set stu = server.CreateObject(&quot;Student.clsStudent&quot;)
//with stu
stu.StudentID = Request(&quot;StudentID&quot;);
stu.FName = Request.Form(&quot;FName&quot;);
stu.LName = Request.Form(&quot;LName&quot;);
stu.Course = Request.Form(&quot;Course&quot;);
stu.Payment = Request.Form(&quot;Payment&quot;);
stu.PaymentDone = Request.Form(&quot;PaymentDone&quot;);
//end with
blnResult = stu.Save();
if (blnResult) // = true then
Response.Write(&quot;<h2>Success!!!<br>Your information has
been added for processing!</h2>&quot;);
else
Response.Write(&quot;<h2>Operation failed!<br>Press 'Back'
button of your browser and try again. If the error
persists, call technical support!</h2>&quot;);
//end if
stu = null;//set stu = nothing

%>
</body>
</html>


At least, it doesn't give me a familiar error message.
Try to use the same approach and see what happens.

By the way, here's the link to the article, which helped to find the right syntax:

hi,

i am also facing the same problem. i wish to invoke a dll which is created in vb using active server pages library. even this simple component is not working, i am getting error. codings are given below. let me know how to solve. if u have some good samples please send me thr' mail. i will be helpful.

VB Coding

project name: car
class name: mycar

Private MyResponse As Response

Public Sub ProcessForm()
Dim strForm
strForm = &quot;<form name=frmCar action=MyCar.asp?qs=1 method=post>&quot;
strForm = strForm & &quot;Name: <input type=text name=txtName><BR>&quot;
strForm = strForm & &quot;Model: <input type=text name=txtModel><BR>&quot;
strForm = strForm & &quot;Color: <input type=text name=txtColor><BR>&quot;
strForm = strForm & &quot;Price: <input type=text name=txtPrice><BR>&quot;
strForm = strForm & &quot;<input type=submit value=Submit><BR>&quot;
strForm = strForm & &quot;</form>&quot;
MyResponse.Write (strForm)
End Sub

after compiled this program into a dll i called in asp using the following code. but i am getting an error if i run that asp file.


ASP Coding

<%
dim objCar
Set ObjCar = Server.CreateObject(&quot;Car.MyCar&quot;)
objCar.ProcessForm
%>


the error message is:
Car error '800a005b'
Object variable or With block variable not set
/portal/lenin/mycom/MyCar.asp, line 7

bye

If u want to use the object in your server side script you could use ActiveXObject or Server.CreateObject but u need to put the &quot;new&quot; word to your sintax:

var IE = new ActiveXObject(&quot;HTMLParser.IE&quot;);
var IE = new Server.CreateObject(&quot;HTMLParser.IE&quot;);

Personally i use the seccond one in my asp pages...
<%@ LANGUAGE=JSCRIPT %>
<%
var IE = new Server.CreateObject(&quot;HTMLParser.IE&quot;);
%>
