SqlConnection con = null;
try
{
con = new SqlConnection(cs);
SqlCommand cmd = con.CreateCommand();
con.Open();
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "WEB_Login ";
cmd.Parameters.Add( "@userName ", SqlDbType.VarChar, 50).Value = user.UserName;
cmd.Parameters.Add( "@userPwd ", SqlDbType.VarChar, 50).Value = user.UserPwd;
object o = cmd.ExecuteScalar();
if (o != null)
{
int iCount = Int32.Parse(o.ToString());
if (iCount == 0)
{
return true;
}
