Strange behaving XMLHTTP

[kajol]

Hi everyone

I am trying to get the content of any webpage (URL) using XMLHTTP, and it
is working fine for me, but suddenly I have got

a URL "http://www.bizrate.com/" which is causing a system error and the
error is

System.Runtime.InteropServices.COMException(0xC00C E56E): System error:-
1072896658

here is the code, which I am using to get the content

''''''''''''''''''''''''''''''''''''''''''''''
Dim a As Object
a = CreateObject("Microsoft.XMLHTTP")
a.open("GET","http://www.bizrate.com/",False)
a.Send("")
TextBox1.Text = a.ResponseText
''''''''''''''''''''''''''''''''''''''''''''''

Can anybody help me to solve this problem, I have tried it using VB6 also,
and VB6 is also showing the same error.

One more thing I want to say about this, is that, I have got the content of
the URL "http://www.bizrate.com/" by typing the

address into the addressbar of the browser (IE), and got the HTML from
view->source, and then saved the HTML into my

localhost and changed the URL by "http://localhost/testpage.html and the
application worked for me, but it is not working

when the URL is used with XMLHTTP

Here is a snippet in C# that I extracted from a project on GotDotNet,
showing you how to do this using a .NET object, instead of a COM component.

Thanks for the reply
I have tested with this .NET object and it is working fine
for the URL I have spacified, but can u do the same thing
for me using XMLHTTP, because I have developed a lot of my
project by XMLHTTP and at this point I do not want to
change from XMLHTTP to webreq/res

IMHO, It would be easier to use a Facade pattern.

Create an internal object, of your own, that behaves just like XMLHTTP.
Give it the same properties and methods as XMLHTTP (but only the ones that
you actually use... don't bother with the rest). Within your own object,
call the .NET object to do the actual work.

Then, go through your code. In every place where you are creating an
XMLHTTP, create one of your internal objects instead. Change only the
declaration and the "create object" call. Leave the rest. When you
recompile your app, you will be free of XMLHTTP.

Sorry, I can't provide code to make XMLHTTP work. I haven't used that
object in about three years, and even then, only lightly. I'm no expert in
solving problems with it. If you are determined to stick with it, I can
provide only encouragement. Perhaps another responder on the NG can provide
some more detail.
