Hi Mike,

I would review the tutorial section at the top of this thread for the step by step procedure, but bascially the imports are placed at the top of the code behind page or top of the script section at the top of the page. Depending on the method you are using. ASP.NET 1.0 or 1.1 specifically.

Quote ...

b.Code the "meat" of the Login in page.
- Mine is in the code behind rather than a script block, but the principles are the same.
- Add the following Imports to your code behind, just above the class declaration.
Code:
Imports System.Web.Security ' ||||| Required Class for Authentication
Imports System.Data ' ||||| DB Accessing Import
Imports System.Data.OleDb ' |||||| Access Database Required Import!

Imports System.Configuration ' |||||| Required for Web.Config appSettings |||||

This will provide the library imports you need for Authentication, accessing an OleDB (i.e. Access), and accessing the web.config file (contains your connection string)

Hi Mike,

Visual Web Develper or Visual Studio 2005 is in ASP.Net 2.0 and not 1.1. So some modification of this code would need to be done, as there are some differences which makes this code non-functional.

I highly recommend you go to this link and watch and walkthrough the tutorial videos.

I plan to post a ASP.Net 2.0 login tutorial very soon, now that my work project has concluded.

Thanks

Re: Updated : Simple ASP.Net Login Page

Hi Paladine, that tutorial worked great and my login is now working from my Access DB

I don't know if i'm allowed to ask this question here, but here goes!

When the user has logged in and they are taken to the Default.aspx page i would like a 'Welcome [UserName goes here]' feature showing who they have successfully logged in as

I'm a complete newbie to ASP.Net and i'm sure it will be very easy for you to tell me

Thanks again

Rich

No worries Rich,

Good question. See page 2 of this tutorial on how to do just what you asked.

Re: Updated : Simple ASP.Net Login Page

Paladine, thanks for your help so far. As of now, my login pages load in Visual QWeb Developer Express (Only validation works, and when i login with user id and pw, the page just reloads with the pw text field blank again. I dont get an error connecting to database or anything). However, when I check it out on the server, i get a big configration error. It is something like :

Configuration Error

Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Parser Error Message: It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.

Source Error:

Line 6: Line 7: <system.web>Line 8: <roleManager enabled="true" />Line 9: <authentication mode="Forms" />Line 10: <compilation defaultLanguage="vb" debug="true" />

Below is my full web.config file. (not as same as yours, but does it need to be just with the source file location changed?)



<configuration>

<appSettings>

<addkey="strnConn"value="PROVIDER=Microsoft.Jet.OLEDB.4.0;DATA SOURCE=D:\Inetpub\wwwroot\students\teamg\IUser\teamg.mdb;User ID=Admin;Password=;" />

</appSettings>

<system.web>

<roleManagerenabled="False" />

<authenticationmode="Forms" />

<compilationdefaultLanguage="vb"debug="true" />

<customErrorsmode="Off" />

<traceenabled="true"requestLimit="10"pageOutput="true"traceMode="SortByTime"localOnly="false" />

</system.web>

<connectionStrings>

<addname="myConnection"connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\Inetpub\wwwroot\students\teamg\IUser\teamg.mdb;Persist Security Info=True"

 

providerName="System.Data.OleDb"/>

</connectionStrings>

</configuration>

I have used your query for MS access, your same form code, and same functions in my login.aspx.vb file, (mostly cut and paste

). Im not sure what is causing this error?

Also, I would like to redirect a validaded user from my Acess Database to my menu.aspx page Any help would be appreciated
