It is hard to say what the problem is, but I would suggest that you put a break point in the code. Then check the objects to figure out which object is still set to Nothing. Once you figure out which object is set to Nothing then you might have a better idea of what is going on. If for some reason the code is getting executed in the load event the text boxes would not exist yet. Anyway, just a thought, hope it helps.

Usually this error will come when you are trying to use an object that is not been initialized yet. Make sure all objects are initialized before you use them.

My codes is shown below. Hopefully it should create a dataset. But how do I create a dataset in code using these values. Something like
<br />
Dim NewDataSet AS Dataset MadData.Cusomer_Lookup(Parameters here)
?
Public Class MadData<br />
'get application settings<br />
<br />
<br />
<br />
<br />
Public connectionString As String = ConfigurationManager.ConnectionStrings("MADConnectionString").ConnectionString<br />
<br />
Public Function Customer_Lookup(ByVal CustomerType As Integer, ByVal CustomerForename As String, ByVal CustomerSurname As String, ByVal LimitedTradingName As String, ByVal NonTradingName As String, ByVal AddressMobile As String, ByVal Records As Integer, ByVal Query As String) As DataSet<br />
<br />
'get the entity name to use for the DataSet table<br />
Dim dbConnection As New SqlConnection(connectionString)<br />
Dim dbDataSet As New DataSet<br />
<br />
Try<br />
'Create Command object for sp<br />
Dim dbCommand As SqlCommand = New SqlCommand("Customer_Lookup", dbConnection)<br />
dbCommand.CommandType = CommandType.StoredProcedure<br />
<br />
'input parameter variables - CustomerType<br />
Dim dbParameter As SqlParameter = dbCommand.Parameters.Add("@CustomerType", SqlDbType.Int)<br />
dbParameter.Direction = ParameterDirection.Input<br />
dbParameter.Value = CustomerType<br />
<br />
'input parameter variables - CustomerForename<br />
Dim dbParameter1 As SqlParameter = dbCommand.Parameters.Add("@CustomerForename", SqlDbType.VarChar)<br />
dbParameter1.Direction = ParameterDirection.Input<br />
dbParameter1.Value = CustomerForename<br />
<br />
'input parameter variables - CustomerSurname<br />
Dim dbParameter2 As SqlParameter = dbCommand.Parameters.Add("@CustomerSurname", SqlDbType.VarChar)<br />
dbParameter2.Direction = ParameterDirection.Input<br />
dbParameter2.Value = CustomerSurname<br />
<br />
'input parameter variables - LimitedTradingName<br />
Dim dbParameter3 As SqlParameter = dbCommand.Parameters.Add("@LimitedTradingName", SqlDbType.VarChar)<br />
dbParameter3.Direction = ParameterDirection.Input<br />
dbParameter3.Value = LimitedTradingName<br />
<br />
'input parameter variables - NonTradingName<br />
Dim dbParameter4 As SqlParameter = dbCommand.Parameters.Add("@NonTradingName", SqlDbType.VarChar)<br />
dbParameter4.Direction = ParameterDirection.Input<br />
dbParameter4.Value = NonTradingName<br />
<br />
'input parameter variables - AddressMobile<br />
Dim dbParameter5 As SqlParameter = dbCommand.Parameters.Add("@AddressMobile", SqlDbType.VarChar)<br />
dbParameter5.Direction = ParameterDirection.Input<br />
dbParameter5.Value = AddressMobile<br />
<br />
'input parameter variables - Records<br />
Dim dbParameter6 As SqlParameter = dbCommand.Parameters.Add("@Records", SqlDbType.Int)<br />
dbParameter6.Direction = ParameterDirection.Input<br />
dbParameter6.Value = Records<br />
<br />
'input parameter variables - Query<br />
Dim dbParameter7 As SqlParameter = dbCommand.Parameters.Add("@Query", SqlDbType.VarChar)<br />
dbParameter7.Direction = ParameterDirection.Input<br />
dbParameter7.Value = Query & "%"<br />
<br />
'open the Connection; run the sp; transform to a DataSet<br />
Dim dbDataAdapter As SqlDataAdapter = New SqlDataAdapter(dbCommand)<br />
dbDataAdapter.Fill(dbDataSet)<br />
<br />
Catch ex As System.Exception<br />
<br />
Throw ex<br />
<br />
<br />
Finally<br />
'tidy up<br />
dbConnection.Close()<br />
dbConnection.Dispose()<br />
<br />
End Try<br />
<br />
Return dbDataSet<br />
<br />
End Function<br />
<br />
End Class

The screen real estate, good user experience of the application and Memory alone would dictate this limit right?

Hi,
I'm wondering how to do this, I'm working on the on a datagrid and I'm using windows authentication. I managed to get username on to a login form, but I want it to be stored into the database.The code of web config looks like:
authentication mode="Windows"
identity impersonate="true"
And the Login page looks like on(Page_load):
Response.Write(Page.User.Identity.Name);
Thanks.

|
|
What exactly is ur problem??
If u want to get the windows login name then use:
HttpContext.Current.User.Identity.Name
or else tell us what is the exact problem.
All the Best...

|
|
Thanks,
I want is when any one uses the website the Windows Login name should appear in a particular datagrid column automatically.
Thanks.
|
|
|
|
|
Your problem is solved or not????
|
|
|
|

Not yet solved. When I try using: HttpContext.Current.User.Identity.Name; I get error: Only assignment, call, increment, decrement, and new object expressions can be used as a statement.
Thanks

When you post code in a forum you need to check the box below that says Ignore HTML tags in this message (good for code snippets)
Otherwise the code gets removed and we won't see it.
Thanks,

Check the datatype of the data what you are sending from front end to the database.

Your code will fail with this sort of error whenever your strings contain a single-quote (e.g. "Fred's Project"). Try searching for "SQL Injection" or look at Parametorized SQL[^].

use the ToShortDateString() method...
DateTime dt = new DateTime();
string str = dt.ToShortDateString();
