I could really use some help on this one. I've been fighting it now for several days and we are supposed to start testing early next week.I am subscribing to 4 web services all hosted by the same company. The integration with 1, 2 and 3 all went fine, but on the fourth I keep getting the very unhelpful error:
System.Web.Services.Protocols.SoapException = {"Server was unable to process request. ---> Object reference not set to an instance of an object."}
[code]...

View 2 RepliesI have a website written in C# that was running fine on one server. We moved it to another server and have a couple issues. I am mainly a VB.NET coder but can do a few things in C#. This is not a project - it is a website and can open it in VS2008 no problem. This is an admin site for the whole website where the user can add customer comments, etc. When logging in, it works fine. I can go to one of the admin pages after logging in and works. If I go to two other different pages, I get this error:
Object reference not set to an instance of an object.
[Code]....
It turns out this is in the main.master page and it is used by the other pages that load fine. The ApplicationTitle variable is set right in the web.config file and like I said, it shows on the other pages.
My question is why would this code work fine for some pages and not two others? All of these admin pages are under a folder called Admin and the web.config file is in the root folder of the website. Its almost like these two pages cannot see the web.config file in the root folder? Why would that be if thats the case?
I have been using the code,

I am going to be receiving data in a web service. After I receive this data I will be mapping it to a data transfer object. I want to be able to catch exceptions if the data from the service is missing any of the required values, times out or any data is malformed.
What can I do to generally catch these exceptions?
I have an Asp.net web service that I created using Visual Studio 2005. I can acess the web service in my test environment, call methods and return data as expected. If this web service is published to the outside world (Outside of the company firewall), it will return a null why this might be happening? The same code is being used,against the same database. The only difference is that the published website is giving back the null reference exception. If I type in the URL for the web service "https://secure.theSiteGeist.com/wsIndigo.asmx" a list of methods for the web service is displayed in my browser. Yet if I try and call any methods on the web service I get back the null reference exception. Note that the URL I posted above is not the real name of my web service, but is just used for reference sake.

View 1 RepliesI am trying to read a string of xml into a dataset by using the following code
[Code]....
As I proceed to bind the 'dsParameters' to a gridview, I was thrown the 'The IListSource does not contain any data sources'. As I step through my code, I found that xmlSR is null. Any idea why is that so?
In my project I have have a query in my Webservice
cmd=new SqlCommand("Select * From Record ;",conn);
conn.Open();
DataReader reader=cmd.ExecuteQuery();
now I want to return this Extracted data which may contain various rows and column
How can it be sent.???
One way is to Send it as XML Document But I don't know how to do this i.e. How to convert this set of record in to XML Document. and then How to retrieve values from this Document in a GridView at the requesting side.
I am trying to handle the unhandled exceptions in my project.I tried with this following code in my web.config filebut it is not at all redirecting to an error page which i have created instead of that it is throwing an exception in my code itselef. How to print the error description over therein my custom error page.
---------------------------------------------------------------------------------------------------
<sys.web>......<customErrors mode="On" defaultRedirect="~/Error.aspx"></customErrors>...</sys.web>
---------------------------------------------------------------------------------------------------
And even i tried in Global.asax page in Application_Error() method like below
 Exception ex = Server.GetLastError();Response.Redirect("~/Error.aspx?errmsg="+ex.message);Server.ClearError();
And in my Error.aspx.cs page i have placed a label and i have written code like this
protected void Page_Load(object sender, EventArgs e)Â Â Â Â Â Â Â {
        Label1.Text=Request["errmsg"];
     }
But it is not getting redirected my error page and not displaying anything on it.
I have ObjectDataSource and GridView on one of the pages of my asp.net web project.
To initialize ObjectDataSource i use Init event:
protected void ObjectDataSource1_Init(object sender, EventArgs e)
{
ObjectDataSource1.EnablePaging = true;
ObjectDataSource1.TypeName = "CustomerDataSource";
ObjectDataSource1.DataObjectTypeName = "Customer";
ObjectDataSource1.SelectMethod = "GetCustomers";
ObjectDataSource1.UpdateMethod = "Update";
ObjectDataSource1.SelectCountMethod = "GetCustomersCount";
ObjectDataSource1.MaximumRowsParameterName = "maximumRows";
ObjectDataSource1.StartRowIndexParameterName = "startRowIndex";
}
Somewhere in DAL:
public static List<Customer> GetCustomers(int maximumRows, int startRowIndex)
{
try {
... some select to database here...
}
catch (Exception ex)
{
Utils.LogError(ex);
throw ex;
}
}
Now let's imagine that GetCustomers for some reason throws an exception. How could i catch this exception and handle it? I know i can use Application_Error, but i would like to catch this exception somehow on my page and show some friendly message to the user.
