Question

See more:

i have a user table in the SQL Server in which the fields are:
UserID --> Int,
Username --> Varchar(40),
Password --> Varchar(50),
UserType --> Varchar(10),
IsSuperUser --> Bool,
EmailAddress --> Varchar(255)

when a user signin in his account there i was checking failure attempts for three times. But the user is a IsSuperUser then he can signin several times otherwise the user gets the alert message for first, second and third attempts and later on the user will be locked. Now the IsSuperUser handles and unlocks the locked user. how can i achieve this please anybody help me

What I have tried:

if (ObjUser.IsSuperUser)
    Response.Redirect("~/Signin.aspx", false);
else
    Reaming users count code here... // <-- Everything works fine here.

Here ObjUser is business class object having property IsSuperUser get and set;
If i enter username capital letters then the user is not considering the user as IsSuperUser. For this i have i have converted to lower but no chance how can i achieve this

Absolutely nothing to do with the question!

And be warned: you'll need to provide a lot more information than you have here if you want anyone to help you.

Solution 2

using Matrix = MathNet.Numerics.LinearAlgebra.Matrix<double>;

And again, absolutely nothing to do with the question!

Why have you posted the same non-solution twice?

Solution 3

My solution is

ObjUser.IsSuperUser = (dr["UserName"].ToString() == uname.ToLower() && Convert.ToBoolean(dr["IsSuperUser"]) == true) ? true : false;

That's terrible! First you compare a Boolean value against true, then you use a conditional operator to convert it to what is was to start with!
