How to set individual page open in WPF C#

Question

1.00/5 (3 votes)

See more:

string uname, pwd, pri, employee_id;
uname = txtUsername.Text;
pwd = txtPassword.Password;
pri = cmboSelectUser.Text;
employee_id = "";
DataSet ds = Globalvariables.Globals.select("select username,password,privilege,usertype,employee_id from add_user where username ='"+ uname + "' and password = '"+pwd+"'");
if (ds != null && ds.Tables[0].Rows.Count > 0)
{

}

What I have tried:

string uname, pwd, pri, employee_id;
                uname = txtUsername.Text;
                pwd = txtPassword.Password;
                pri = cmboSelectUser.Text;
                employee_id = "";
                DataSet ds = Globalvariables.Globals.select("select username,password,privilege,usertype,employee_id from add_user where username ='"+ uname + "' and password = '"+pwd+"'");
                if (ds != null && ds.Tables[0].Rows.Count > 0)
                {

}

Your code is vulnerable to SQL Injection[^]. NEVER use string concatenation/interpolation to build a SQL query. ALWAYS use a parameterized query.

You're storing your users' passwords in plain text. Don't do that!

Beyond those obvious critical security errors, you haven't actually asked a question.
