On my page I have a dropdown for country.
On my asmx service I want to get the value of the dropdownlist to filter the next input which will be state/providence.
My code on the asmx:
[Code]....
I want to add another clause to the WHERE statement to restrict Country = @Country so I will need to get that value to the web service.

I'm running a WebMethod when a user clicks a link and I want the service method to have access to the clients SessionID but when I try to initialise a new string it returns a null value.
So to clarify(an example):
[WebMethod]
public string myMethod()
{
string s = Session.SessionID.ToString();
//rest of method here...
}
string s is returning null value. The code works fine on a postback and the method works without SessionID but I really want/need to be able to use a callback and need to be able to use the SessionID

I am creating a Web Service, which will be used by a client to send data to our Database.The client will be sending close to 30 fields that will be updated to our table. If I write a Web method, I will need to have all these 30 fields as parameters to that method. Is there a better way than sending all of them as parameters?

I have a web service called service1. Is it possible to pass the parameter related to the service to a class library so for e.g.
Service1.service ws = new Service1.service();
Service1.UserDetails ud = null;
now if I call a method that exists in a class and pass ud. Cam i do that because I am trying to do this and I am getting an error. Do i need to add a web
reference to this service in the class library My method call is like this
authenticateUser.Authenticate(ud, UserName);
and in the class libary I have
public void Authenticate( Service1.UserDetails ud , string UserName)
{

I have a method in wcf which returns stream of custom object. I need to deserialize this stream at client side, but my custom class which is exposed as data contract is not visible through client proxy. When I add a dummy operation contract which returns the custome object I am able to get this custom class. I dont want to write this dummy method as there are many such custom classes.
Is there any way to expose data contract without writing any operation contract that returns or accepts data contract type object?

Rightnow I'm saving the values in an xml file and fetch the values in the windows application.But this is not practical when creating xml files with random numbers(Scan125.xml,Scan7867.xml,etc).

A customer reported that our asmx web service is continually increasing in memory (mem usage as well as private bytes). We are able to reproduce the problem in our lab with Windows 2003 Server SP2 (fully patched) on some of the machines. The customer is using Windows 2008.
We created a Hello World web service targeting the 2.0 framework built under VS2005 SP1 and a test client that continues to call it. The memory increases steadily - approximately 40K per client request. If the test app is paused, the memory remains the same. When it is closed, the memory drops. Explicit calling of GC.Collect does not drop the memory.
We have run the memory profiler on the service and the leak is all native memory. We have uninstalled/re-installed the Framework on one of the machines but no difference. To our knowledge all of the security and IIS settings are not modified. We have compared app pool, default web site and virtual directory properties to machines that have no problem and they are identical.

I have spent a couple of days on this one. I have an ASP.NET website that has Linkbuttons on
the Default.aspx page.. I added a WebService to the Website because later on the WebService will
subscribe to a Provider(Feed) of News, Sports and Weather and things like that. So when a Linkbutton
on the Default.aspx page is clicked it will connect to the link in the WebService which will load the News,
Sports or Weather onto the Default.aspx web page.
The problem is I can't get the LinkButton to execute the Link in the WebService. The link will call the page up
to where you see all of the Web References. But then if you want to execute one of those references you
have to click its link and the Invoke button that will follow. My questioh is how can the link on my Default.aspx
page execute the link in the WebService. Now I changed the LinkButton into an <a href> but I still can't execute
the link in the WebServices. I always use www.Microsoft.com as the link when testing and I wasn't sure about the return type
so I put "void" for an HTTPRequest, so below is the link from the Default.aspx web page and below that is he asmx file:

Im having problems passing a value through a querystring that is split by a '&' eg :
?value=Apples & Pears
Only the "Apples" part is being picked up by response.querystring("value"). I have other values which are split by a space eg:
?value=red shoes which I can successfully extract "red shoes".

In this answer to my question of how to insert data into SQL Server he mentioned passing parameters instead of string concatenation like I currently have.
Is this really necessary for security? If so, what exactly is passing parameters? When i google it I get a lot about stored procedures. Is that what I want, I do not know about stored procedures....yet.
EDIT:
Ok, here is what I got. It seems to update the database correctly and eventually I will change the hard coded ints to inputs from a label. confirm if how I did this is not vulnerable to any sql injection or hacks.

We have several web applications that create a shopping cart, save it to a database, then redirect to a centralized web application to process and accept payment for the shopping cart. Right now, we are using GUIDs for the shopping cart IDs and passing those GUIDs in the querystring to the payment application. We are using GUIDs so that a user cannot easily guess the shopping cart ID of another user and simply plug that ID into the URL.
Now, using GUIDs in the database is bad for indexing and using GUIDs in the URL does not truly prevent a user from accessing another cart. However, using passing integers around would make it too easy.
What is the best and most secure way to pass the IDs from the individual applications to the centralized payment application?
I know that some people may say, "Who cares if someone else wants to pay for someone else's shopping cart?" However, we have the same concern when passing IDs to the page that displays the receipt and that page includes the customer's name.

My students are working on an ASP.net VB application for a Web Programming competition and we are having problems with a page where we want an URL string to return all values from our database.
Here is the page:
[URL]
If you use the jobs by category menu on the left side, if you select a job category (ie retail) it will pull up all the jobs from that category. By using a query in the URL like this:
[URL]
What we need is the URL that would show all jobs regardless of the category. I'm not sure how to do this with asp.net VB. I'm sure it's probably not all that hard, we just don't know the syntax to make it happen.

I am probably totally missing the point here but....
How can I pass a 'var' into another method?
(I am using linq to load XML into an Enumerable list of objects).
I have differernt object types (with different fields), but the final step of my process is the same regardless of which object is being used.
XNamespace xmlns = ScehmaName;
var result = from e in XElement.Load(XMLDocumentLocation).Elements(xmlns + ElementName)
select new Object1
{
Field1 = (string)e.Element(xmlns + "field1"),
Field2 = (string)e.Element(xmlns + "field2")
};
var result2 = Enumerable.Distinct(result);
This code will vary for the different type of XML files that will be processed. But I then want to iterate though the code to check for various issues:
foreach (var w in result2)
{
if (w.CheckIT())
{
//do something
}
}
What I would love is the final step to be in a method in the base class, and I can pass the 'var' varible into it from each child class.
