    Create a database in MSAccess and save database as Studentrecords.mdb. Now add a table to the database using the following format
    Code:
    StudentNO  Text
    FName      Text
    SurName    Text
    Password   Text
    Save the table as tblStudent.

    Now create a new file and name it login.asp
    Code:
    <html>
    
    <head>
    <title>Home</title>
    </head>
    <body bgcolor="#003366">
    <center>
    <%
    'StudentNo Of Logged in user
    Dim Username
    'Retrieving Username
    Username=Request.QueryString("username")
    'Invalid Username password
    if UserName <> "" then
    	Response.Write "<font color='#FFAA00'>"
    	Response.Write "<font face='Verdana' size=2>"
    	Response.Write"Invalid UserName Password. Please Re-login"
    	Response.Write "</font></font>"
    end if
    %>
      <form method="POST" action="verify.asp">
      <table border="1" cellspacing="1" bordercolor="#111111" id="AutoNumber1" height="82">
        <tr>
          <td height="23"><font color="#FFFFFF" face="Verdana" size="2">Student Number</font></td>
          <td width="148" height="23">
            <p align="center">
            <font face="Verdana" color="#FFFFFF">
            <input type="text" name="username" size="20" value=""><font size="2">
            </font></font>
          </td>
        </tr>
        <tr>
          <td height="22"><font color="#FFFFFF" face="Verdana" size="2">Password</font></td>
          <td width="148" height="22">
          <p align="center"><font color="#FFFFFF" face="Verdana"><input type="password" name="password" size="20"></font></td>
        </tr>
        <tr>
          <td width="210" colspan="2" height="22">
          <p align="center"><font face="Verdana"><font color="#FFFFFF">
          <input type="checkbox" name="rememberme" value="ON"></font><font size="2" color="#FFFFFF">Remember 
          Me</font></font></td>
        </tr>
        <tr>
          <td width="210" colspan="2" height="22">
          <p align="center"><font face="Verdana" color="#FFFFFF"><input type="submit" value="LogIn" name="B1"><font size="2">&nbsp;</font><input type="button" value="New User" name="B2" onClick = "location.href('signup.asp');"></font></td>
        </tr>
      </table>
      </form>
      </center>
    </div>
    </body>
    </html>
    
    Now create another file and name it verify.asp
    Code:
    <body bgcolor="#003366">
    <%
    
    'Connection String
    Dim Conn

    	end if
    else
    	'Invalid User
    	Response.Redirect "login.asp?UserName=blank"
    end if
    %>
    
    Upload the all the 3 files viz login.asp, verify.asp and Studentrecords.mdb in the current folder and you are ready to go.

    StudentNO can behave as that. The concenptually article will explain how to go about it and it can always be extended for the custom fields in the database.

    Still my answer remains the same but i will add something more.

    If one verification process fails you can go with the other but you can also test if the username contains some predefined valid email format and then go for email validation or the username one.

    There is a check for blank username and password and so see if it is executed correctly and if not it should display the message
    Code:
    if UserName <> "" or Password <> "" then
    .
    .
    .
    else
        'Invalid User
        Response.Redirect "login.asp?UserName=blank"
    end if

    For check box / radio button there is a value attribute which will be set if that is selected and you can determine which one is selected provided you have unique values for each and then you can update the database accordingly.

    Dear shabbir,

    Your code is working perfect, thank you for sharing this.

    But i have a question.

    I would like to direct diffent users to diffent pages.
    Like this:
    -> User A has to redirect to page welcome1.asp
    -> User B has to redirect to page welcome2.asp
    -> User C has to redirect to page welcome3.asp
    -> User D has to redirect to page welcome1.asp
    and so on...

    Can you tell me how to implement this in you code.

    Thank you very much
    Peter

    Just redirect after validating. You need to check the type of user which is also fetched when validating the user and then use the ASP's redirect function.

    I want to keep my database in a separate folder but the script won't work.

    connStr = connStr + server.MapPath("/private/mrecords.mdb")

    Hey Shabbir, great code!!

    I implemented it to check a MS Access field for an email address. The problem is I set it up so that if a user accidentally types in the wrong address, they are re-directed to a page that allows them to re-enter the address again. If they re-enter the correct Email from that page, they get this message: “ADODB.Recordset error '800a0e78' Operation is not allowed when the object is closed”.


    I looked into the problem and I believe it is a syntax issue, ref: http://databases.aspfaq.com/database/what-should-my-connection-string-look-like.html

    Thanks so much!

    Yes its a syntax issue and you need to have the Recordset open to execute the SQL.
