[MCPD]

if u mean

Session ["abc"] =0;

i know that the session variable cant be increased

i cant do this

Session["abc"]+=1;

[radcaesar]

A Session variable retains the value until its destroyed or the browser is closed.

Refer ASP .NET tutors for more informations.

Debug this code line by line. It never works, if you approach like this.

What that mean
if (Datareader1.Read()) ?

Debug and check whether it searches for correct username and password.

DataReader.Read() thats my datareader
and it check if the command is return something from the sql
and this is what containt the datareader1

Datareader1 = MyCom1.ExecuteReader();

And MyCom1 Is

MyCom1 = new SqlCommand("select * from Users where UserName='" + TextBox1.Text + "'", MyCon);
