DataSource Controls :: Reading Excel Files To Store Into Sqlserver Database - OleDbException Was Unhandled By User Code
Feb 1, 2010i'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"
Jan 16, 2010I downloaded a sample Rolodex from here: [URL] the file to download is at the bottom of the page and it is called 'RolodexDatalist.zip (6.71 kb)' So I changed the HTML to it points to my SQL Server DB. I changed the ConnectionString to this:
<connectionStrings>
<add name="CustomersConnectionString" connectionString="Data Source=EXCEL-4J2W8KYNPSQLEXPRESS;Initial Catalog=Customers;Integrated Security=True"
providerName="System.Data.SqlClient" />
</connectionStrings>
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. Object reference not set to instance of an object. Troubleshooting Tips: use the "new" keyword to set an instance of an object.' This line is yellow:

DataSource Controls :: SqlException Not Getting Sent Back To C# Code?
Jan 22, 2010I have a straight forward SP that throws a divide by zero error like:
[Code]....
Note that even though I am calling RAISEERROR() its not getting returned back to my code if I use this try catch. When I remove the try catch like above it returns fine. I made sure that the severity level is >= 11 so it's not ignored. At this point I'm out of ideas because everything I can find published seems to say that this should work.
FYI my C# code is pretty straight forward I don't think it has anything to do with it as I have a wide open Exception catch and it's never getting called so I'm not posting it to keep this message brief.

Forms Data Controls :: Throw The Exception Back To Page_Load Error: ArgumentNullException Was Unhandled By User Code
Nov 19, 2010I'm trying to throw the exception back to Page_Load but the throw statement causes error: ArgumentNullException was unhandled by user code. How can that be fixed? Also, I can't see Label1.Text displayed on the page after the ArgumentNullException occurs because the page is not re-load. If there is no exception, it's fine to not reload the page. How can I see the Label1.Text displayed?
protected void Page_Load(object sender, EventArgs e)
{
try
{
...do something here...
}
catch (ArgumentNullException ae)
{
System.Diagnostics.Debug.Write(ae.Message);

Web Forms :: NullReference Exception Unhandled By User Code?
Mar 18, 2011I'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
Get
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.

DataSource Controls :: SqlException Timeout Expired?
Jun 9, 2010We are seeing the following timeout error being logged into our Event Viewer every now and then. We are using LINQ to connect to the SQL Server 2008 and the connection string is defined in the web.config file.One wierd thing I noticed is that the .NET framework is timing out trying to detect if this is SqlCe connection string. Why is it trying to waste time and then timing out when we have a SQL Server 2008 as the database?
What can I do to fix this problem?
