Hello and thank you for taking a moment. Let me say that I am brand new to Web Services. Please forgive my ignorance on some of these issues. I have created a web service in VS 2005.  When I go to run the code my web service description (test) pages come up fine.( These are the pages that give a description of the web service along with the available methods) I click on the name of one of the methods and come to the the page that lets me invoke that method.

When I click the 'invoke' button I receive a page not displayed error and when I refresh VS then throws me the following Error:

Request format is unrecognized for URL unexpectedly ending in '/GetEmployees'.

indeed the url of this page is http://localhost:1223/WebSite12/Service.asmx/GetEmployees

I just don't know what to do in order to get the method to give me the information I want. The book I am borrowing code from says it should work. Below is my asmx and codebehind. Any help you could provide would be greatly appreciated.- Jason

Service.asmx ( this is set as my start page of my project)

App_Code\Service.cs (CodeBehind)]

Hello and thanks again. I am assuming the strings you are referring to are my SQL expressions. I am not 100% what you mean by "visible'. Again ... I apologize for my ignorance. Do you mean that the expreesion can only be used when the particular method is called?

You said to work properly it must be accompanied by form data and web service headers.Not really sure what this means completely. Do you mean that I have to create an aspx with a form on it? I don't really know what Web Service Headers are?

One thing I didn't mention is that on my Invoke page for GetEmployees(). There is a message underneath my Invoke button that says this message:

Page cannot be displayed... Internal server error

Yes, probably just indicates that the variable scope issue we've already discussed generated an exception, regarding which the server knows more about but isn't telling.  It's your server, don't take that crap.  Turn on debugging for the project.  Also turn on in-client-browser error output for the web site.  The place to set these two items varies depending on the version you are using.  Turn it all back off before you put anything on the public 'net.

GetEmployeesCount()

You still didn't tell us if this other Invoke works.  I suspect it doesn't.

Ben74, thank you so much for posting this.  It is very easy to forget to add this in the web.config especially if you did not start the project as a webservice project. The error does not even give a clue that this is the issue.  I was pulling my hair out for a while with this error.  Adding the above lines to the web.config fixed the error for me.
