Scenario/Summary
In this lab, we will demonstrate how to save user activity data in a database. We will be creating a new form to display
the user activity data, a new dataset to contain the data, a data access class to structure the code, and a function within
the data access class to save users’ activity data when users visit the Personnel form page (frmPersonnel.aspx). We
will also be adding server side validation to the frmPersonnel for you added in the previous lab and update or main
menu for the new functionality.
Instructions for Week 3 iLab: “User Activity Monitoring”
Click on the link above to view the tutorial.
This video will show you how to set up user activity monitoring using Visula Studio and C#.
The tutorial has audio.
Deliverables
All files are located in the subdirectory of the project. The project should function as specified: When you visit the
Personnel form page (frmPersonnel.aspx), a record should be saved in the tblUserActivity table with the IP address,
form name accessed (frmPersonnel), and the date accessed. When you click the “View Activity” button, you should see
at least one record with this information. When the user goes to the frmPersonnel web form and enters data the following
business rules are to be enforced:
• Fields may not be empty or filled with spaces. If any field is empty, turn that field background color to yellow and
add to/create an error message to be shown in the error label.
• The end date must be greater than the start date. If the end date is less than the start date turn both date fields
yellow and add to/create an error message to be shown in the error label.
If all fields validate properly, then the session state items should be set properly and the user should see the
frmPersonnelVerified form with all the values displayed. You will also add a new item to frmMain that will take the user
to the new frmUserActivity form you added. Add the proper link and a hyperlinked image to allow the user to select this
new option. Once you have verified that everything works, save your website, zip up all files, and submit in the Dropbox.

STEP 1: Data Connection, Dataset and Data Access Class (10 points)
1. Open Microsoft Visual Studio.NET 2008.
2. Open the PayrollSystem website by clicking on it in the Recent Projects list, or by pulling down the File menu,
selecting Open Website, navigating to the folder where you previously saved the PayrollSystem, and clicking Open.
3. Download the PayrollSystem_DB.MDB file from Doc Sharing and save it on your local computer. (Note: your
operating system may lock or block the file. Once you have copied it locally, right click on the file and select Properties
and then Unblock if available). Then add it to the PayrollSystem website as follows: In Visual Studio, in the Solution
Explorer click Website, Add Existing Item, then navigate to the PayrollSystem_DB.MDB file you downloaded and click
the Add button.
4. Now we need to create a new connection to the PayrollSystem_DB.MDB. To begin, click View Server Explorer.
5. When the Server Explorer toolbox appears, click the Connect to Database button.
6. When the Add Connection dialog appears, click the Change button. In the “Change Data Source” dialog, select
MS Access Database File; Uncheck Always use this Selection; then click OK.

7. Click the Browse button to navigate to the PayrollSystem_DB.mdb file in your website folder, then click “Open”.
(NOTE: Be sure you select the PayrollSystem_DB.mdb file in your PayrollSystem website folder, not the one you
originally downloaded from Doc Sharing!) Click Test Connection. You should receive a message that the test
connection succeeded. Click OK to acknowledge the message, then click “OK” again to close the Add Connection
dialog.
8. The PayrollSystem_DB.mdb should be added to the Server Explorer. Expand the database, then expand the
Tables entry under the database until you see tblUserActivity. Leave the Server Explorer window open for now as you
will be returning to it in a moment.

9. Create a new dataset by selecting Website Add New Item. Under Templates, select the Dataset item. Enter
dsUserActivity.xsd for the name. Click Add.

Add Data Set
10. Click here for text discription of this image.
11.
12. If the following message appears, select Yes. You want to make this dataset available to your entire website.
13. If the TableAdapter Configuration Wizard dialog appears, click Cancel. (We will be configuring a Data Adapter for
this dataset later in C# code, so we do not need to run this wizard.)
14. Drag-and-drop the tblUserActivity table from the Server Explorer window into the dsUserActivity dataset in the
editor window.
NOTE: If you see a message that says your connection uses a local data file that is not in the current project, that
indicates you did not select the correct PayrollSystem_DB.mdb file when you created your data connection. To fix this
problem, click No, then right-click on PayrollSystem_DB.mdb in the Server Explorer window and choose Modify
Connection. Click the Browse button, navigate to the PayrollSystem_DB.mdb file that is in your PayrollSystem website
folder, and click Open. Test the connection, then click OK.
15. Click the Save icon on the toolbar to save the dsUserActivity.xsd dataset.
Click on image to enlarge.
Dataset Saved
16. Click here for text discription of this image.
17. (You can now close the Server Explorer window if you wish.)

18. Create a new class to contain the C# code that will access this dataset. To do so, click Website, Add New Item.
In the Add New Item dialog, select the Class template, and enter clsDataLayer for the name. Make sure the Language
is set to Visual C#. Click “Add”.
Click on image to enlarge.
Add DataLayer Class
19. Click here for text discription of this image.
20. If the following message appears, select Yes. You want to make this class available to everything in your solution.
21. Add the following to the top of your class, below any other using statements created for you by Visual Studio:
// Add your comments here
using System.Data.OleDb;
using System.Net;
using System.Data;
22. Add the following three functions inside the squiggly braces for the “public class clsDataLayer” class, above the
beginning of the “public clsDataLayer()” constructor:
// This function gets the user activity from the tblUserActivity
public static dsUserActivity GetUserActivity(string Database)
{// Add your comments here
dsUserActivity DS;
OleDbConnection sqlConn;
OleDbDataAdapter sqlDA;
// Add your comments here
sqlConn = new OleDbConnection(“PROVIDER=Microsoft.Jet.OLEDB.4.0;” +
“Data Source=” + Database);
// Add your comments here
sqlDA = new OleDbDataAdapter(“select * from tblUserActivity”, sqlConn);
// Add your comments here
DS = new dsUserActivity();
// Add your comments here
sqlDA.Fill(DS.tblUserActivity);
// Add your comments here
return DS; }
// This function saves the user activity
public static void SaveUserActivity(string Database, string FormAccessed)
{// Add your comments here
OleDbConnection conn = new OleDbConnection(“PROVIDER=Microsoft.Jet.OLEDB.4.0;” +
“Data Source=” + Database);
conn.Open();

OleDbCommand command = conn.CreateCommand();
string strSQL;
strSQL = “Insert into tblUserActivity (UserIP, FormAccessed) values (‘” +
GetIP4Address() + “‘, ‘” + FormAccessed + “‘)”;
command.CommandType = CommandType.Text;
command.CommandText = strSQL;
command.ExecuteNonQuery();
conn.Close(); }
// This function gets the IP Address
public static string GetIP4Address()
{string IP4Address = string.Empty ;
foreach (IPAddress IPA in
Dns.GetHostAddresses(HttpContext.Current.Request.UserHostAddress)) {
if (IPA.AddressFamily.ToString() == “InterNetwork”) {
IP4Address = IPA.ToString();
break; } }
if (IP4Address != string.Empty) {
return IP4Address; }
foreach (IPAddress IPA in Dns.GetHostAddresses(Dns.GetHostName())) {
if (IPA.AddressFamily.ToString() == “InterNetwork”) {
IP4Address = IPA.ToString();
break;} }
return IP4Address; }
STEP 2: frmUserActivity, frmPersonnel, frmMain (10 points)
18. Create a new Web form called frmUserActivity. Switch to Design Mode and add a Label and GridView (found
under the Toolbox, Data tab) having the following properties:
Property
Value
Label – Text
User Activity
GridView – (ID)
grdUserActivity
19. Go to the Page_Load method and add the following code:
if (!Page.IsPostBack) {
// Declares the DataSet
dsUserActivity myDataSet = new dsUserActivity();
// Fill the dataset with what is returned from the function
myDataSet = clsDataLayer.GetUserActivity(Server.MapPath(“PayrollSystem_DB.mdb”));
// Sets the DataGrid to the DataSource based on the table
grdUserActivity.DataSource = myDataSet.Tables["tblUserActivity"];

Binds the DataGrid
grdUserActivity.DataBind(); }
20. Open the frmMain form, add a new link button and image button to point to the new frmUserActivity. Find an
image to use for the image button and add the new option as View User Activity.
21. Go to the frmMain Page_Load and add the following code:
// Add your comments here
clsDataLayer.SaveUserActivity(Server.MapPath(“PayrollSystem_DB.mdb”), “frmPersonnel”);
22. On the frmUserActivity form, add the CoolBiz logo hyperlinked logo at the top of the page so that when clicked
the user is returned to frmMain.
23. In the Solution Explorer, right click on the frmMain.aspx form and select Set As Start Page. Run your project.
When you open the project, a record should be saved in the tblUserActivity table with the IP address, form name
accessed (frmPersonnel), and the date accessed. When you click the View Activity button, you should see at least one
record with this information.
24. You will now add server side validation code to the frmPersonnel page. Currently, when the Submit button is
pressed, the frmPersonnelVerified page is displayed. This is because the frmPersonnelVerified page is set as the
Submit button’s PostBackUrl property. Instead of having the page go directly to the frmPersonnelVerified page when
the Submit button is pressed, we want to do some server side validation. If any of the validation rules fail, we will
redisplay the frmPersonnel page with the fields in question highlighted in yellow with an error message displayed.
First, it is important to understand what is currently happening when the submit button is pressed. This is causing a
postback of the form to the frmPersonnelVerified form. When this postback happens, all of the data in the fields on the
frmPersonnel form are sent to the frmPersonnelVerified form as name value pairs. In the Page_Load code of
frmPersonnelVerified these values are picked up from the Request object and displayed. Each name value pair will be
in the Request object as the ID of the control containing the value and the value itself. We can pass data between
pages by using Session state instead. In order to do validation on the values but still have the values visible on the
frmPersonnelVerified page, we will need to change not only the PostBack URL of the frmPersonnel page but also how
the frmPersonnelVerified form is getting the data – it will need to get it from Session state rather than from the Request
object.
Make the following changes:
1. Clear the Submit button PostBackURLProperty on the frmPersonnel form.
2. In the btnSubmit_Click event handler get each value from the data entry fields and set Session state items for
each.
3. Change the frmPersonnelVerified code behind to get the values from the Session state items you created in the
previous step.
When you are done with these steps, you should be able to enter data on the frmPersonnel data entry form and then
click the Submit button. The frmPersonnelVerified page should then be displayed with the values that were in the data
entry fields on frmPersonnel.
Make sure this is all working before proceeding to the next steps.
25. Add a label to the frmPersonnel form with an ID of lblError. Do not place the label to the right or left of any of the
controls on the form. Add it below the controls or above the controls. The text property of this label should be set to an
empty string.
26. Add code to perform server side validation in response to the submit button being clicked. Here are the business
rules we want to enforce (remember this will be server C# code in the frmPersonnel code behind): Fields may not be
empty or filled with spaces. If any field is empty, turn that field background color to yellow and add to/create an error
message to be shown in the error label. The end date must be greater than the start date. If the end date is less than
the start date, turn both date fields yellow and add to/create an error message to be shown in the error label. If all fields
validate properly then the session state items should be set properly and the user should see the frmPersonnelVerified
form with all the values displayed.
27. Lab Hints: To set a value in session state do the following:

Session["txtFirstName"] = txtFirstName.Text;
28. “txtFirstName” is the key and txtFirstName.Text is the value.
29. To get this same value back from the session we use the key and the Session object as follows:
Session["txtLastName"].ToString()
30. There is a Trim method on the string object that will automatically remove spaces from the beginning and end of
a string. Remember, you can turn an object like a Session item object into a string using the Convert class or just using
it’s ToString() method.
31. You may want to create variables to work with for validation rather than using the Request item objects directly.
32. To turn a string into a DateTime object you can use the DateTime method Parse. If you had a date value stored
in a string called strDate, you could turn it into a DateTime object like this:
DateTime myDateTimeObject = DateTime.Parse(strDate);
33. You can compare two DateTime objects by using the DateTime.Compare method. If you had two DateTime
objects called dt1 and dt2 you can check to see if dt1 is greater than dt2 by doing this:
if (DateTime.Compare(dt1,dt2) > 0)
34. DateTime.Compare will return a 0 if the two dates are equal, a 1 if dt1 is greater than dt2, and a -1 if dt1 is less
than dt2.
35. If you put in an invalid date for either of the date fields, you will get an exception/server error when trying to parse
the values. We will address this in a later lab – for now make sure you enter valid dates (valid meaning a date in the
form of mm/dd/yyyy).
36. If I had a TextBox control that was called txtAge and you wanted to set it’s background color you could do this:
txtAge.BackColor = System.Drawing.Color.Yellow;
37. Remember to clear the PostBackURL property of the submit button!
STEP 3: Verify and submit (10 points)
28. View the video above on what functions your lab should have so far.
29. Run your project. When you open the project, and go to the main menu form a record should be saved in the
tblUserActivity table with the IP address, form name accessed (frmPersonnel), and the date accessed. When you click
the View Activity button you should see at least one record with this information. The validation and error display should
work for entering data. All navigation and hyperlinks should work.
Once you have verified that it 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) and for any code you write, or else a five point deduction per item (form, class, function) will be made.
You basically put two forward slashes, which start the comment; anything after the // on that line is disregarded by the
compiler. Then type a brief statement describing what is happening in following code. Comments show professionalism
and are a must in systems. As a professional developer, comments will set you apart from others and make your life
much easier if maintenance and debugging are needed
