Trouble creating an array of a class I created

What am I doing wrong? I made a class and want to create an array of that class and I keep getting "object reference not set ot an instance of an object" when the code hits line 4. Tile is the class I made

1private void usrTurnTile_Load(object sender, EventArgs e)2{3Tile[] objTile =new Tile[20];4objTile[3].Visible =false;5}

adding this fixed it...

for (int i23 = 0; i23 < 20; i23++)

objTile[i23] =newTile();

adding this fixed it...

for (int i23 = 0; i23 < 20; i23++)

objTile[i23] =newTile();

adding this fixed it...

for (int i23 = 0; i23 < 20; i23++)

objTile[i23] =newTile();

Trouble opening a connection to SQL 2000 DB

I'm developing an intranet site in ASP.NET 2.0 but I can't seem to
connect to the DB from within my code. I've created a .vb class that
houses a private Connection() that other functions within the class can
call to connect to the database. In the calling function, I've declared
my connection object and called the "Open" method on the object.
However, when I attempt to execute the stored procedure command by
calling the "ExecuteScalar" method, I get the following error:
"ExecuteScalar requires an open and available Connection. The
connection's current state is closed."
Here's the code from my class:
Imports System.Data
Imports System.Data.SqlClient
Namespace Encompass
Public Class EncompassSecurity
Public Shared Function GetHRIDByNTUserID(ByVal strNTUserID) As String
Dim strHRID As String
'Create command object
Dim cmd As New SqlCommand("usp_Get_HRID_By_NTUserID", Connection())
cmd.CommandType = CommandType.StoredProcedure
'Open DB connection
Dim DBConnection As SqlConnection = Connection()
DBConnection.Open()
'Input parameters
Dim inNTUserParam As New SqlParameter("@dotnet.itags.org.NT_UserID", SqlDbType.VarChar)
inNTUserParam.Direction = ParameterDirection.Input
inNTUserParam.Value = strNTUserID
cmd.Parameters.Add(inNTUserParam)
'Output parameters
Dim outHRIDParam As New SqlParameter("@dotnet.itags.org.HRID", SqlDbType.Int)
outHRIDParam.Direction = ParameterDirection.Output
cmd.Parameters.Add(outHRIDParam)
'Run stored procedure
strHRID = cmd.ExecuteScalar()
Return (strHRID)
'Close DB connection
DBConnection.Close()
End Function
Private Shared Function Connection() As SqlConnection
Dim strConnectionString As String
strConnectionString = ConfigurationManager.ConnectionStrings(
"Conn").ConnectionString
Return New SqlConnection(strConnectionString)
End Function
End Class
End

Manuel Garr, MCPYou have created a Commad object with a connection object which is not open
yet.
Dim DBConnection As SqlConnection = Connection()
DBConnection.Open()
Dim cmd As New SqlCommand("usp_Get_HRID_By_NTUserID", DBConnection)

A command object can be created without the connection being opened.
However, your code is partially correct. The only thing that needs to
be changed is the call to DBConnection.Open() should be made right
before the cmd.ExecuteScalar() call.

A command object can be created without the connection being opened.
However, your code is partially correct. The only thing that needs to
be changed is the call to DBConnection.Open() should be made right
before the cmd.ExecuteScalar() call.

Troubles reference this pointer in external class file

I'm wanting to reference page controls from a cs file in the app_code
directory. I'm getting a _Defaullt could not be found, missing
directive or assembly reference error. Very simple example below.
Default.aspx.cs:
using System;
using System.Web.UI;
public partial class _Default : Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
Class1.UpdateButtonText(this);
}
}
Class1.cs
using System;
public class Class1
{
public Class1()
{
}
public static void UpdateButtonText(_Default global_Default)
{
}
}

http://peterkellner.netThis is impossible as the App_Code directory is compiled prior to your aspx
files.

Thanks,
Makes sense to me now. When I moved Class2 directly into the aspx.cs
file it of course worked. Hadn't really thought about the order of
compilation.
