I want to create a login page with access database connection.
All I want to do is, In asp.net page I want to add username,
password textbox and also submit button. Once I click the submit button I want to see whether the username and password are existing in the access database(Table name-UserTable) or not. If it exists in the databse then redirect to some other asp.net page. If it is not then stay in the same page with error message.

I am new in the .Net , It may be a silly question.

Since I am not familier with syntax and C# also.

I want to use C# and asp.net....

Please give me some ideas and solution for this issue.

Pls help me out!

Thanks in Advance,

You can also put the connection string in web.config file. Web.config file is not downloable from the web.

This week I created a secure login page so I can do some database administration online by passing SQL statements. I didn't want anyone else to have access except me. I did what you describe but in vb.net and my password is hardwired in the code right now. I just created another directory and set the permissions in the web.config of the new directory to deny all users as follows:


<configuration>
<system.web>
<authorization>
<deny users="?" /> <!-- deny all users -->
</authorization>
</system.web>
</configuration>

The web.config in the root directory should have something like this


<authentication mode="Forms" >
<forms name ="SQLadmin" loginUrl = "logon.aspx" protection="All" timeout="60" />
</authentication>

<authorization>
<allow users="*" /> <!-- Allow all users -->
</authorization>

When someone tries to access the page in the directory where you have denied permissions you are redirected to a logon.aspx page that you have to create that has something like this:

Private Sub bntLogin_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles bntLogin.Click
If Page.IsValid Then
If txtUN.Text = "your username" And txtPW.Text = "yourpassword" Then
'redirects to the originally requested page
FormsAuthentication.RedirectFromLoginPage(txtUN.Text, True)
Else
lblMessage.Visible = True
lblMessage.Text = "Invalid Login. Try Again"
End If
End If
End Sub

In the place of my hardwired username and password, you simple put in code to lookup it up in your database.

You click a button and you are authenicated by your code and you are then redirected to the origally requested source by
FormsAuthentication.RedirectFromLoginPage. If the second parameter is set to true as shown above a persistent cookie is set so you will not have to login again from the same brower. If set to false you have to login with each new browser session.

I found the key to making this work in getting parameters set correctly in root directory web.config and the protected directory web.config files.

It is pretty simple and I hope the wrapping does not make this unreadable.

Hope this helps. It seems to work great.
