Hi my name is vishal for past 2 days i have been breaking my head on how to have list users only created by that manager when the same manager enters into the form in c# windows forms with sql server 2008.
So i have also created a form for registering normal user named:
frmUser and given below is my
c# code of that form:
namespace Mini_Project
{
public partial class frmUser : Form
{
public frmUser()
{
InitializeComponent();
}
private void btnCreate_Click(object sender, EventArgs e)
{
SqlConnection conn = new SqlConnection("Data Source=NPD-4\\SQLEXPRESS;Initial Catalog=Task;Integrated Security=true");
if (conn.State != ConnectionState.Open)
{
conn.Open();
}
SqlCommand cmd = new SqlCommand();
cmd.Connection = conn;
cmd.CommandType = CommandType.Text;
int autoGenId = -1;
cmd = new SqlCommand("Insert into [dbo].[UserDetail2](user_first_name,user_last_name,user_dob,user_sex,email,username,password,status,row_upd_date,created_by,LoginAttempts)" + "Values(@user_first_name,@user_last_name,@user_dob,@user_sex,@email,@username,@password,@status,GetDate(),@created_by,@LoginAttempts); Select @autoGenId=SCOPE_IDENTITY();", conn);
cmd.Parameters.AddWithValue("@user_first_name", txtFName.Text);
cmd.Parameters.AddWithValue("@user_last_name", txtLName.Text);
cmd.Parameters.AddWithValue("@user_dob", dtDOB.Value);
if (cboSex.SelectedIndex == 0)
{
cmd.Parameters.AddWithValue("@user_sex", "Male");
}
else if (cboSex.SelectedIndex == 1)
{
cmd.Parameters.AddWithValue("@user_sex", "Female");
}
else if (cboSex.SelectedIndex == 2)
{
cmd.Parameters.AddWithValue("@user_sex", "Transgender");
}
cmd.Parameters.AddWithValue("@email", txtEmailID.Text);
cmd.Parameters.AddWithValue("@username", txtUsername.Text);
cmd.Parameters.AddWithValue("@password", txtPassword.Text);
cmd.Parameters.AddWithValue("@status", 1);
cmd.Parameters.AddWithValue("@Created_by", 1);
cmd.Parameters.AddWithValue("@LoginAttempts", 0);
cmd.Parameters.Add("@autoGenId", SqlDbType.Int).Direction = ParameterDirection.Output;
cmd.ExecuteNonQuery();
autoGenId = Convert.ToInt32(cmd.Parameters["@autoGenId"].Value);
((MDIParent1)this.MdiParent).updateUserActivities(autoGenId, 1, txtFName.Text + "User detail was added successfully");
MessageBox.Show("User Detail was added successfully", "Task", MessageBoxButtons.OK, MessageBoxIcon.Information);
conn.Close();
this.Close();
}
The above code works
Fine!
i have login form(
frmLogin) given below is c# code of
frmLogin:
namespace Mini_Project
{
public partial class frmLogin : Form
{
public frmLogin()
{
InitializeComponent();
}
private bool ManagerUser(string username, string password)
{
bool success = false;
SqlConnection conn = new SqlConnection("Data Source=NPD-4\\SQLEXPRESS;Initial Catalog=Task;Integrated Security=true");
SqlCommand cmd = new SqlCommand();
cmd.Connection = conn;
cmd.CommandType = CommandType.Text;
cmd = new SqlCommand("Select @count = Count(*) from [dbo].[ManagerDetail2] where username=@username and password=@password and LoginAttempts< 3", conn);
cmd.Parameters.AddWithValue("@username", txtUsername.Text);
cmd.Parameters.AddWithValue("@password", txtPassword.Text);
cmd.Parameters.Add("@count", SqlDbType.Int).Direction = ParameterDirection.Output;
conn.Open();
cmd.ExecuteNonQuery();
if (Convert.ToInt32(cmd.Parameters["@count"].Value)>0)
{
success = true;
cmd = new SqlCommand("Update [dbo].[ManagerDetail2] set LoginAttempts=0 where username='" + txtUsername.Text + "'", conn);
cmd.ExecuteNonQuery();
}
else
{
success = false;
cmd = new SqlCommand("Update [dbo].[ManagerDetail2] set LoginAttempts=LoginAttempts+1 where username='" + txtUsername.Text + "'", conn);
cmd.ExecuteNonQuery();
}
conn.Close();
return success;
}
private bool ValidateUser(string username, string password)
{
bool success = false;
SqlConnection conn = new SqlConnection("Data Source=NPD-4\\SQLEXPRESS;Initial Catalog=Task;Integrated Security=true");
SqlCommand cmd = new SqlCommand();
cmd.Connection = conn;
cmd.CommandType = CommandType.Text;
cmd = new SqlCommand("Select @count = Count(*) from [dbo].[UserDetail2] where username=@username and password=@password and LoginAttempts< 3", conn);
cmd.Parameters.AddWithValue("@username", txtUsername.Text);
cmd.Parameters.AddWithValue("@password", txtPassword.Text);
cmd.Parameters.Add("@count", SqlDbType.Int).Direction = ParameterDirection.Output;
conn.Open();
cmd.ExecuteNonQuery();
if (Convert.ToInt32(cmd.Parameters["@count"].Value)>0)
{
success = true;
cmd = new SqlCommand("Update [dbo].[UserDetail2] set LoginAttempts=0 where username='" + txtUsername.Text + "'", conn);
cmd.ExecuteNonQuery();
}
else
{
success = false;
cmd = new SqlCommand("Update [dbo].[UserDetail2] set LoginAttempts=LoginAttempts+1 where username='" + txtUsername.Text + "'", conn);
cmd.ExecuteNonQuery();
}
conn.Close();
return success;
}
private void btnLogin_Click(object sender, EventArgs e)
{
if ((txtPassword.Text == "password") && (txtUsername.Text.ToLower() == "admin"))
{
Module.AUser_ID=1;
MDIParent1 h = new MDIParent1();
h.Show();
this.Close();
}
else
{
string username = txtUsername.Text;
string password = txtPassword.Text;
bool validUser = ValidateUser(username, password);
bool validmanager = ManagerUser(username, password);
if (validUser)
{
Module.User_ID = 1;
MDIParent1 m = new MDIParent1();
m.Show();
this.Close();
}
if (validmanager)
{
Module.MUser_ID = 1;
MDIParent1 g = new MDIParent1();
g.Show();
this.Close();
}
else
{
MessageBox.Show("Invalid user name or password. Please try tomorow ", "Task", MessageBoxButtons.OK, MessageBoxIcon.Warning);
txtUsername.Focus();
}
}
}
private void btnCancel_Click(object sender, EventArgs e)
{
Application.Exit();
}
The above code works
Fine!
I have form named:
frmTask which enabled manager to assign a task to a user which he has created/registered into the application.
Given below is my c# code of
frmTask:
private void frmTask_Load(object sender, EventArgs e)
{
dtAssignDate.MinDate = dtAssignDate.Value;
string user=("Select u.user_id as user_id,(u.user_first_name+' '+u.user_last_name+'|'+right('000'+convert(varchar,u.user_id),5)) as Name from UserDetail2 u where u.status=1");
DataTable mt = new DataTable();
SqlConnection cont = new SqlConnection("Data Source=NPD-4\\SQLEXPRESS;Initial Catalog=Task;Integrated Security=true");
if (cont.State != ConnectionState.Open)
{
cont.Open();
}
SqlCommand hcr = new SqlCommand(user, cont);
mt.Load(hcr.ExecuteReader());
lstUsers.DataSource = mt;
lstUsers.ValueMember = "user_id";
lstUsers.DisplayMember = "Name";
lstUsers.SelectedValue = 0;
}
The above code works to some extent and not the way i want!
The problem i am facing is i am getting all users from table:UserDetail2 into listbox(
lstUsers).
What i want is when a
manager(has username and password) enters into application,registers/add new users to application. When that same manager has entered into that application and when he enters into
frmTask i want only list of
users created by
him only in a
listbox?
Can anyone help me please!
Can anyone tell me what modifications must i need to do in my c# code and where? Can anyone help me/guide me to solve my problem?! Any help/guidance in solving of this problem would be greatly appreciated!
