Hi,

I've just read the article about Data Access (http://www.asp.net/learn/dataaccess/default.aspx?tabid=63). Now I'm trying to create a DAL my self. But I get lots of errors (18 of them).
Error examples:

--------------------------------

Error 1 'string' does not contain a definition for 'Convert' c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\folder\462f30a9\7f7f39b4\App_Code.mxcujrb-.2.cs 8362 

[System.Diagnostics.DebuggerNonUserCodeAttribute()]
public void SetIPNull() {
    this[this.tableVisitors.IPColumn] = System.Convert.DBNull; <-- Line 8362
}

--------------------------------

Error 5 'string' does not contain a definition for 'DBNull' c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\folder\462f30a9\7f7f39b4\App_Code.mxcujrb-.2.cs 13882 

if ((IP == null)) {
    this.Adapter.InsertCommand.Parameters[1].Value = System.DBNull.Value; <-- Line 13882
}
else {
    this.Adapter.InsertCommand.Parameters[1].Value = ((string)(IP));
}

--------------------------------

Error 9 'string' does not contain a definition for 'Data' c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\folder\462f30a9\7f7f39b4\App_Code.mxcujrb-.2.cs 13907 

this.Adapter.InsertCommand.Parameters[5].Value = ((System.DateTime)(CreatedDate));
System.Data.ConnectionState previousConnectionState = this.Adapter.InsertCommand.Connection.State;
if (((this.Adapter.InsertCommand.Connection.State & System.Data.ConnectionState.Open) != System.Data.ConnectionState.Open)) { <-- Line 13907
    this.Adapter.InsertCommand.Connection.Open();
}

--------------------------------

Thanks!
