CIS 407 A – ILAB 6 OF 7
i L A B O V E R V I E W
Scenario/Summary
In this week's lab, we will create a login form, validate a user based on their login name and password,
and allow them to access the system or not. We will assign a session variable to determine the level of
security the user has and allow certain functions to be displayed or not displayed in the existing
frmPersonnel form depending on the assigned security level. (NOTE: In some cases the instructions for
this lab will be less specific than in earlier labs, because you are expected to apply what you have learned
in earlier weeks. Refer to the detailed instructions in previous weeks' labs if you need to do so.)

Deliverables
When you try to log in, if you use User Name = Mickey and Password = Mouse, the frmMain form should
open with all links visible. If you use User Name = Minnie and Password = Mouse, the frmMain form
should open with only the Salary Calculator, View Personnel, and Search options should be available.
You will have a new option called Manage Users that will allow you to add new users and remove or
update existing users. Once you have verified that it works, save your website, zip up all files, and submit
in the Dropbox.
Note on database connections: We are using a SQLDataSource control for the Edit employees feature
we added. You should be using the connection string stored in the web.config file for your database
connection for this control. Rather than creating a new connection each time, just use this connection. If
you change the folder where your website is (e.g., you copy each week's work to a new location), you will
need to update the web.config. The advantage of using the database connection in the web.config is that
you only have to set the configuration in one location.
Before starting this week's lab, make sure everything is working and that all database connections are
properly configured.

STEP 1: Login Form (10 points)
1. Open Microsoft Visual Studio.NET 2008.
2. 2. Click the ASP.NET website named PayrollSystem to open it.
3. Create a new web form named frmLogin.
4. Drop a login control onto the form.
5. Set the properties of the login control as follows:
PROPERTY VALUE
DestinationPageUrl frmMain.aspx
TitleText
Please enter your UserName
and Password in order to log
into the system
6. Add the CoolBizProductions, Inc. logo to the frmLogin form. Do not hylerlink the logo.
7. Highlight everything in the form, then click Format, Justify, Center. Save your work.
8. Go to the Solution Explorer, right-click on frmLogin, and left-click on Set As Start Page. Then run
the website to check if the web form appears correctly.

STEP 2: Login Check (10 points)
9. Create a new DataSet called dsUser. Use the table tblLogin as the database table for this
dataset. Do this in the same way you added datasets in the previous labs.
10. Open the clsDataLayer and add the following function:
// This function verifies a user in the tblUser table
public staticdsUserVerifyUser(string Database, stringUserName, stringUserPassword)
{
// Add your comments here
dsUser DS;
OleDbConnectionsqlConn;
OleDbDataAdaptersqlDA;
// Add your comments here
sqlConn = newOleDbConnection("PROVIDER=Microsoft.Jet.OLEDB.4.0;" +
"Data Source=" + Database);
3. // Add your comments here
sqlDA = newOleDbDataAdapter("Select SecurityLevel from tblUserLogin " +
"where UserName like '" + UserName + "' " +
"and UserPassword like '" + UserPassword + "'", sqlConn);
// Add your comments here
DS = newdsUser();
// Add your comments here
sqlDA.Fill(DS.tblUserLogin);
// Add your comments here
return DS;
}
11. Double-click on the login control you added. Add the following code to the login control
Authenticate event handler:
// Add your comments here
dsUserdsUserLogin;
// Add your comments here
stringSecurityLevel;
// Add your comments here
dsUserLogin = clsDataLayer.VerifyUser(Server.MapPath("PayrollSystem_DB.mdb"),
Login1.UserName, Login1.Password);
// Add your comments here
if (dsUserLogin.tblUserLogin.Count< 1)
{
e.Authenticated = false;
return;
}
// Add your comments here
SecurityLevel = dsUserLogin.tblUserLogin[0].SecurityLevel.ToString();
// Add your comments here
switch (SecurityLevel)
{
case"A":
// Add your comments here
e.Authenticated = true;
Session["SecurityLevel"] = "A";
break;
case"U":
// Add your comments here
e.Authenticated = true;
Session["SecurityLevel"] = "U";
break;
4. default:
e.Authenticated = false;
STEP 3: Test and Submit (10 points)
12. Open the frmPersonnel form and add the following code to its Page_Load() function:
// Add your comments here
if (Session["SecurityLevel"] == "A") {
btnSubmit.Visible = true;
//Add your comments here
} else {
btnSubmit.Visible = false;
}
13. Set the start page as frmLogin.aspx. Run the website. Try to log in with both User Name = Mickey
and Password = Mouse and User Name = Minnie and Password = Mouse. Any other user ID and
password should not allow you to log in.
14. When the user logs in we want to restrict what they can see and do based on their user role. The
role is stored in the database table tblUserLogin. Mickey Mouse has all privileges whereas Minnie
Mouse has read only privileges. We want to control the visibility of the links on the frmMain page.
15. Initially we did not set the ID of any of the Link Button or Image Button controls that we used on
frmMain. In order to make our code more maintainable we will change the IDs as follows:
Option Link Button ID Image Button ID
Annual
Salary
Calculator
linkbtnCalculator imgbtnCalculator
Add New
Employee
linkbtnNewEmployee imgbtnNewEmployee
View User
Activity
linkbtnViewUserActivity imgbtnViewUserActivity
View
Personnel
linkbtnViewPersonnel imgbtnViewPersonnel
Search
Personnel
linkbtnSearch imgbtnSearch
Edit
Employees
linkbtnEditEmployees imgbtnEditEmployees
16. Modify the main form so that the following options are turned off for nonadmin users:
o Add New Employee
o View User Activity
o Edit Employees
17. You now have a web application that honors the role of the logged in user. We don't have a way
of managing the user roles and users in the system.
5. 18. Add a new form called frmManageUsers that will allow the user to add new users. The user will
also need to be able to view all users and modify or delete any of the users in the database. Add
a main form option called Manage Users that is only accessible to admin users. Add the link and
image buttons as we have done in the past. Add the CoolBiz logo that is hyperlinked as you did in
previous assignments.
o For the security level of the user, use a dropdown list control to allow the user to select
from A or U.
o Name the controls with names that make sense.
o Add code as appropriate to the code behind and clsDataLayer.
19. Hints:
o Make sure you reestablish your database connection if you copied the files from a
previous lab.
o Update any DataSource controls you added with the new Payroll database location.
o You can turn a control on or off by setting it's Visible property.
o You can add a data entry form for new users and a grid displaying all users all on the
same form.
o To force a gridView to refresh call its DataBind method.
o In order to use the Advanced SQL Generation option (allowing you to update/delete
records) there must be a primary key defined on the table you are generating SQL for.
tblUserLogin needs to have a primary key set on the UserID column. You can do this in
Access.
20. Test your application to make sure you are logging in with an invalid user id. Try to log in with
both Minnie and Mickey and make sure the UI adjusts by the role properly. Make sure you can
utilize the Manage Users functionality to add/modify/delete and view user information. Once you
have verified that everything works, save your project, zip up all files, and submit in the Dropbox.
NOTE: Make sure you include comments in the code provided where specified (where the " //
Your comments here" is mentioned); also, any code you write needs to be properly commented,
or else a five point deduction per item (form, class, function) will be made.
