web service returns blank page when invoking
 

Hi Everyone!

I am working on a project for a directed study class and am having
problems with webservices.

I have .NET Framework version 1.1.4322.573 with IIS and Frontpage
Extensions installed and Visual Studio 2003. These are all a fresh
install as I removed and re-installed to try and fix the problem to no
avail.

What Happens
============
In Visual Studio I can create a new Web Service project, say
WebService1, and all is created fine on IIS. I then open the default
file created by Visual Studio (service1.asmx) and uncomment the "Hello
World" web service.

[WebMethod]
public string HelloWorld()
{
return "Hello World";
}

I can then browse to http://localhost/WebService1/s ervice1.asmx and
click the link for the web method HelloWorld. I then click the Invoke
button.
A new window opens and it is blank, there is nothing there. On 1 other
machine I have seen this work on campus where XML was returned with the
"Hello World" text in it, but not here. When I try to view source in
Internet Explorer the text for "Source" in the view menu is grayed out.

On 2 machines I have tried to get this to work and I get the same
result. I really do not know where to go.

I am writing an Instant Messenger app for C# and Web Services but I am
at a wall here where I can't move further until I can get the web
services to respond.

Thanks in advance for any help you can send my way!

Did you rebuild the Web Service after making the change?

Re: web service returns blank page when invoking
 

Thanks Kevin for your response. I rebuilt the solution and web service
and I also created a new blank web serivice project in Visual Studio
that was just the default "HelloWorld" web service. Neither will work.
Thanks!

Sorry to disappoint you, David, but I'm mystified. I can't think of a reason
offhand. You might try using the Debugger to step through the code when you
run it using F5.

Re: web service returns blank page when invoking
 

Ok so I decided to load it in Mozilla instead of IE and Mozilla
displayed it but with an error: At the top of the page it reads:

"This XML file does not appear to have any style information associated
with it. The document tree is shown below."

Below it is:
<string>Hello World</string>

Re: web service returns blank page when invoking
 

Post the source code from Mozilla.

Re: web service returns blank page when invoking
 

Very odd. I copied and pasted this into NotePad, saved it as an XML file,
and opened it in IE, with no problems. Perhaps it is an IE setting that is
causing your problem.
