Hi all,
I am trying to use a Stored Procedure which takes two parameters (login, pw) and returns the user info.
If I execute the SP manually, I get
Session_UID User_Group_Name Sys_User_Name
------------------------------------ -------------------------------------------------- -
NULL Administrators NTMSAdmin
No rows affected.
(1 row(s) returned)
@RETURN_VALUE = 0
Finished running [dbo].[p_SYS_Login].
But with the code below, I only get the return value.
do you know how to get the other values shown above like
Session_UID, User_Group_Name, and Sys_User_Name ?
if you see the commented part below code. I tried to add some output parameters but it doesn't work with incorrect number of parameters error.
string strConnection = Settings.Default.ConnectionString;
using (SqlConnection conn = new SqlConnection(strConnection))
{
using (SqlCommand cmd = new SqlCommand())
{
SqlDataReader rdr = null;
cmd.Connection = conn;
cmd.CommandText = "p_SYS_Login";
//cmd.CommandText = "p_sys_Select_User_Group";
cmd.CommandType = CommandType.StoredProcedure;
SqlParameter paramReturnValue = new SqlParameter();
paramReturnValue.ParameterName = "@RETURN_VALUE";
paramReturnValue.SqlDbType = SqlDbType.Int;
paramReturnValue.SourceColumn = null;
paramReturnValue.Direction = ParameterDirection.ReturnValue;
//SqlParameter paramGroupName = new SqlParameter("@User_Group_Name", SqlDbType.VarChar, 50);
//paramGroupName.Direction = ParameterDirection.Output;
//SqlParameter paramUserName = new SqlParameter("@Sys_User_Name", SqlDbType.VarChar, 50);
//paramUserName.Direction = ParameterDirection.Output;
cmd.Parameters.Add(paramReturnValue);
//cmd.Parameters.Add(paramGroupName);
//cmd.Parameters.Add(paramUserName);
cmd.Parameters.AddWithValue("@Sys_Login", textUserID.Text);
cmd.Parameters.AddWithValue("@Sys_Password", textPassword.Text);
try
{
conn.Open();
object result = cmd.ExecuteNonQuery();
int returnValue = (int)cmd.Parameters["@RETURN_VALUE"].Value;
if (returnValue == 0)
{
Hide();
Program.MapForm.Show();
}
else if (returnValue == 1)
{
MessageBox.Show("The username or password you entered is incorrect", "NTMS Login", MessageBoxButtons.OK, MessageBoxIcon.Warning);
}
else if (returnValue == 2)
{
MessageBox.Show("This account is disabled", "NTMS Login", MessageBoxButtons.OK, MessageBoxIcon.Warning);
}
else
{
MessageBox.Show("Database error. Please contact administrator", "NTMS Login", MessageBoxButtons.OK, MessageBoxIcon.Warning);
}
}
catch (Exception ex)
{
string message = ex.Message;
string caption = "MAVIS Exception";
MessageBoxButtons buttons = MessageBoxButtons.OK;
MessageBox.Show(
message,
caption,
buttons,
MessageBoxIcon.Warning,
MessageBoxDefaultButton.Button1);
}
}
}
Thanks for your help.
