Create data table in sql server by the following query
create table tblUser(
id int identity(1,1) primary key,
u_Name nvarchar(200),
u_Password nvarchar(200),
u_Email nvarchar(200)
)
Now create the store procedure for register the user and check the user name already exists.
create proc SP_Register
@u_Name nvarchar(200),
@u_Password nvarchar(200),
@u_Email nvarchar(200)
as
begin
Declare @Count int
Declare @ReturnCode int
select @Count=COUNT(u_Name)
from tblUser
where u_Name=@u_Name
if @Count>0
begin
set @ReturnCode=-1
end
else
begin
set @ReturnCode=1
insert into tblUser values(
@u_Name,@u_Password,@u_Email)
end
select @ReturnCode as ReturnCode
end
Add the connection string into web.config file
<appSettings>
<add key="ConnectionString" value="Data Source=LAPTOP-ISNBQ76D;Initial Catalog=tutorial;Integrated Security=True"/>
</appSettings>
Now add the Register.aspx web page for register the user and add the following code.
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<div>
<table>
<tr>
<td>User Name:</td>
<td><input type="text" id="txtUserName" runat="server" /> </td>
</tr>
<tr>
<td>Password:</td>
<td><input type="password" id="txtPassword" runat="server" /> </td>
</tr>
<tr>
<td>Email:</td>
<td><input type="email" id="txtEmail" runat="server" /> </td>
</tr>
<tr>
<td colspan="2">
<asp:Label ID="lblError" runat="server"></asp:Label>
</td>
</tr>
<tr>
<td><asp:Button ID="btnRegister" runat="server" Text="Register" OnClick="btnRegister_Click" /></td>
<td><asp:Button ID="btnCancel" runat="server" Text="Cancel" /></td>
</tr>
</table>
</div>
</div>
</form>
</body>
</html>
Now add the following code into the Register.aspx.cs file
using System;
using System.Collections.Generic;
using System.Configuration;
using System.Data.SqlClient;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.Security;
namespace authenticate
{
public partial class Register : System.Web.UI.Page
{
public static string StringCon = null;
SqlConnection conn = null;
protected void Page_Load(object sender, EventArgs e)
{
StringCon = ConfigurationSettings.AppSettings["ConnectionString"];
conn = new SqlConnection(StringCon);
}
protected void btnRegister_Click(object sender,EventArgs e)
{
try
{
string sql = "SP_Register";
SqlCommand cmd = new SqlCommand(sql,conn);
string encriptedPass = FormsAuthentication.HashPasswordForStoringInConfigFile(txtPassword.Value, "SHA1");
cmd.CommandType = System.Data.CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@u_Name",txtUserName.Value);
cmd.Parameters.AddWithValue("@u_Password", encriptedPass);
cmd.Parameters.AddWithValue("@u_Email", txtEmail.Value);
conn.Open();
int returnValue = (int)cmd.ExecuteScalar();
if (returnValue == -1)
{
lblError.Text = "User Name Already Exist! Please Try Another One!";
}
else
{
Response.Redirect("Login.aspx");
}
}
catch(Exception ex)
{
}
finally
{
conn.Close();
}
}
}
}
