Web Forms :: NullReference Exception Unhandled By User Code?
I'm working on having two forms that communicate together. In order to do this, I am passing public value from the source page. Here's how I did it:

In the source page I have:

Public ReadOnly Property CurrentCity() As String
Return txtboxfake.Text
End Get
End Property
Then under page_load of the page I have:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
txtteam.Text = PreviousPage.CurrentCity
txtboxdate.Text = Calendar1.SelectedDate
End Sub

For some reason I keep getting an error that says "NullReference exception unhandled by user code" that points to txtteam.text = PreviousPage.CurrentCity.

Error - System.NullReferenceException Was Unhandled By User Code
I am new to C#. I was doing pretty well, until I ran into the "System.NullReferenceException was unhandled by user code Message="Object reference not set to an instance of an object" error.

Here is the code:

String[] strRoutes;
int k = 0;
String GetRoute(String route)
strRoutes[k] = route;
return route;

Basically I have a gridview using ItemTemplate that calls this function. It may seem like a useless exercise the way it is written, but in the end I want to sort the array then grab the distinct routes in that array.

The gridview piece:

<asp:Label ID="Label4" runat="server"
Text='<%# GetRoute(Eval("OrderRoute").ToString()) %>'></asp:Label>

I don't think the problem is in gridview, it is stopping at the k++.

Installation :: Registry Value Doesn't Exist - HttpException Was Unhandled By User Code
I was researching an issue relating to Excel automation and one of the website recommended to modify the machine.config file. So following I took the following steps:

1. Browsed to folder "c:WINDOWSMicrosoft.NETFrameworkv2.0.50727".
2. Backed Up "machine.config" file.
3. Edited the machine. config file. Re-run the solution. It didn't work.
4. So I restored the machine.config file.

This is the only thing I did. So now whenever I'm running my solution, I get the following error: Unable to make the session state request to the session state server. Please ensure that the ASP.NET State service is started and that the client and server ports are the same. If the server is on a remote machine, please ensure that it accepts remote requests by checking the value of HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesaspnet_stateParametersAllowRemoteConnection.

If the server is on the local machine, and if the before mentioned registry value does not exist or is set to 0, then the state server connection string must use either 'localhost' or '' as the server name. The Build is succeed but the following code of global.asax.vb fire this error:

Application_Error(ByVal sender
As Object, ByVal e
As EventArgs)
Dim err As Exception = Server.GetLastError()
'Response.Write("<h1>" & err.InnerException.Message & "</h1>")
'Response.Write("<pre>" & err.ToString & "</pre>")
Dim vErr As
vErr = err.InnerException.Message.ToString()
Catch ex
As Exception
vErr = "Unknown Server Error"
End Try
'Response.Write("<h1>Polaris.Net Server Error.<BR>Please provide any helpful comments and click the [Submit] button to send details of this error to the systems department.</h1>")
Session("ServerError") = vErr
End Sub

I tried all the googled solutions but didn't work. I even copied the whole solution, including the new web.config file but to no avail.

DataSource Controls :: Reading Excel Files To Store Into Sqlserver Database - OleDbException Was Unhandled By User Code
i've got some problem reading excel files to store into sqlserver database. currently my code has a fileupload control and a button for me to save the excel file into a folder and read the data inside the excel file and write it into the sql database. The code works only if the excel sheet name is Sheet1.xlsx, however i tried upload a diff file named ImportUserFile.xlsx and it gave me the exception below. 'ImportUserFile$' is not a valid name. Make sure that it does not include invalid characters or punctuation and that it is not too long. i have also tried other file names and it seemed only Sheet1.xlsx works.

DataSource Controls :: Error Msg "Null Reference Was Unhandled By User Code"
I downloaded a sample Rolodex from here: [URL] the file to download is at the bottom of the page and it is called ' (6.71 kb)' So I changed the HTML to it points to my SQL Server DB. I changed the ConnectionString to this:

<add name="CustomersConnectionString" connectionString="Data Source=EXCEL-4J2W8KYNPSQLEXPRESS;Initial Catalog=Customers;Integrated Security=True"

Now, everything points to my DB! I thought, ok great, this should be pretty easy. However, when I debug, I get this error message: 'Null reference was unhandled by user code.

WCF / ASMX :: FaultException Was Unhandled By User Code - "Server Was Unable To Process Request"
I have created a web service that interacts with my DAL. It has the usual kind of methods, create, retrieve, update and delete. I have published this web service to our live Windows Server and I can see the web serice URL.The web service works on a few method calls but does not work specifically for one object. I am getting the following error: Fault Exception was unhandled by user code. "Server was unable to process request. ---> Data is Null. This method or property cannot be called on Null values."

To summarise: Web service is live, I can see it in my browser. Some method calls work. One specific one does not. I have verified that the method works (it is just calling a SQL stored proc that does return data).

Access :: Visual Studio Hang On MyConnection.Open() Error "OleDbException Was Unhandled By User Code"
I made and ASP.Net application with C# 2005 with Access database. In my development machine I could run my application and do some actions that connect to database. I use myConnection.Open() method to connecting to database. I also call myConnection.Close() method after each call to opening. But sometimes the application crashes and visual studio hang onmyConnection.Open()and show this error message : " OleDbException was unhandled by user code". I restart application but that problem remains and program hang on myConnection.Open() again.

After restarting IIS this problem disappears. But after some running, the problem appears again. I also see this on our host machine. I think that this is a conflict problem between IIS and Access database but why at most time its running fine and occasionally crash occurs? My system is WinXP with SP2 and IIS 5.1.

Web Forms :: User Controls Are Null When Referenced Inside The Code Behind For The User Control?
I have an ASP.NET4.0 applicationwith some simpleuser controls. The user controls work fine on the design surface (VS.NET 2010), but when they're loaded during application execution,nothing shows up.

Futhermore, the various child controls of the user controlsare null when referenced inside the code behind forthe user control.

The code behind for the user control executes as expected, butany reference to child controlsare null.

It's like ASP.NET isnever parsing the ASCX to create the instances of the child controls.
