hi,
i am using seaparte connection class.

{
internal static string conn;
internal SqlConnection cnUniversal;
internal SqlCommand cmdUniversal;
internal SqlDataAdapter daUniversal;
public string ConnectionString
{
set { conn = value; }
}
public ConncetionClass()
{
conn = System.Configuration.ConfigurationManager.ConnectionStrings["ss"].ToString();
}
public virtual void Initialize()
{
try
{
cnUniversal = new SqlConnection(conn);
daUniversal = new SqlDataAdapter();
cmdUniversal = new SqlCommand();
cmdUniversal.CommandType = CommandType.StoredProcedure;
cmdUniversal.Connection = cnUniversal;
}
catch (Exception e)
{
ErrorLog("dbBasis initialization", e);
}
}
public virtual void Close()
{
if (cnUniversal.State != System.Data.ConnectionState.Closed)
cnUniversal.Close();
}
protected virtual void ErrorLog(string strMessage, Exception e)
{
Exception oException = new Exception(e.InnerException.Message + " \n\n Details:" + strMessage);
throw oException;
}
