Strange Problem With Asp.Net WebService,Help Needed

[batista]

Hi there,


My problem is that, i've created a simple hello world web service
project, and then, when i run it to test the operation,the invoke
button does not open any window.

I mean there is no response when i click the invoke button, no window
containing the output opens.

It just does nothing, no error no exception nothing.

Just to clarify,

my web service url is this
http://localhost/TestWS/Service1.asmx, when i browse it,
it displays helloworld function
the url is

http://localhost/TestWS/Service1.asmx?op=HelloWorld, and it's written

"To test the operation using the HTTP POST protocol, click the 'Invoke'

button "

now when i click on the invoke button link it does nothing?
why?????????

But when i try to browse the url

http://localhost/TestWS/Service1.asmx/op=HelloWorld

it gives me the following exception:

System.InvalidOperationException: Request format is unrecognized

BTW, i'm using asp.net v1.1..

So now plz any help on this.....

Wats wrong in this.???????????

You might want to enable tracing. That way you will be able to find out if
Web Service is working fine on the server. If your web service fails, you
would not get error message if not programmed correctly.

I am having a similar problem, but only on one machine. On my desktop, the
web service (for testing purposes the template with "hello world" section
uncommented) works fine. On my notebook, the WSDL form works, as does the
?op=HelloWorld page. However, clicking on the "Invoke" button opens a blank
"the page cannot be displayed" generice IE error. I have tried reinstalling
IIS (no affect). I am VERY reluctant to reinstall .NET, as I have had no
other problems on this machine.

Both Desktop and Notebook are Windows XP Pro SP2 with all the latest
patches.

Thanks!

Did you ever figure out this problem> I have the exact same problem. On one
machine it works fine. On the other, it doesn't work at all.

I did find a solution to the problem, although I don't like it. I had to
uninstall ALL versions of visual studio, followed by uninstalling all
versions of .NET (which took SQL 2005 with it), then uninstalling IIS (in
windows components). After that was all cleaned out, I installed IIS +
FrontPage extensions again, rebooted, then installed everything I had removed
(VS 03 & 05). At that point, everything was working again (even if I had to
waste a day doing it).

Hope this helps!

nope. I moved the app to another machine (XP) where it works. Problem is on
my Win2000 machine. But I would like to know why its not working.
