问题:

I am a beginner in HTML and ASP and I should write a program that when username and password are admin and user click on the button, the program opens a new ASP page in otherwise the program shows invalid username or password in table.

I write this code but always when I click on the Button, the program shows new ASP page! I write this code in notepad.

<html>
<body>

<form method="post" action="Exam1.asp">
    <table cellpadding="20" border="1" align="center" style="text-align:left;">
        <colorgroup>
        <col style="background-color:pink">
            <col style="background-color:pink">
        </colorgroup>

        <tr>
            <td>
                <p>UserName:</p>
                <p>Password:</p>
            </td>
            <td>
                <input type="text" name="Username">
                <br>
                <br>
                <input type="password" name="Password">
            </td>
        </tr>
        <tr>
            <td><input type="submit" value="Button"></td>
            <td>
                <%If Session("Username")="admin"&Session("Password")="admin" Then%>
                    <form method="post" action="Exam1.asp">
                    </form>
                <%Else%>
                    Invalid username or password.
                <%End If%>
            </td>
        </tr>
    </table>
</form>

</body>
</html>

Thanks for help. Cheers

When you click on the submit button named Button, it will take you to Exam1.asp and send it the information the user typed into the form. Sesson("Username") and Sesson("Password") are not yet defined in your code, but in Exam1.asp they will hold the data that the user typed.
