2. You use Visual Studio .NET to create an application that will process telephone orders.
Your application uses an XML Web service for credit card verification. It also uses several Microsoft SQL Server stored procedures. The XML Web service contacts a third-party credit card processing service to authorize credit card charges. You have access to the source code for the XML Web service and the stored procedures, which were created by your company and are used by several other applications.
Before you deliver your application for comprehensive testing, you need to perform unit testing to ensure that the application performs as expected.
Which three actions should you include in your unit test plan? (Each correct answer presents part of the solution. Choose three.)
A. Use the T-SQL Debugger to step through each stored procedure used by your application and ensure that each one is functioning properly.
B. Add the source code for the XML Web service to your Visual Studio .NET solution. Use the Visual Studio debugger to step through calls to this code.
C. Step through the source code for your application and ensure that it is functioning properly given various application parameters.
D. Examine and validate the input parameters, output parameters, and results from each call to the stored procedures.
E. Examine and validate the values sent to and received from the XML Web service.
F. Contact the third-party credit card processing service to verify that credit card charges issued by your application are being delivered properly by the XML Web service.
Answer: CDE
3. You develop a Windows-based application that accesses a Microsoft SQL Server database. The application includes a form named CustomerForm, which contains a Button control named sortButton. The database includes a table named Customers.
Data from Customers will be displayed on CustomerForm by means of a DataGrid control named DataGrid1. The following code segment is used to fill DataGrid1:
The primary key for Customers is the CustomerID column.
You must ensure that the data will be displayed in ascending order by primary key when the user selects sortButton.
What should you do?
A. Set the Sort property of the DataView object to an empty string.
B. Set the ApplyDefaultSort property of the DataView object to False.
C. Include an ORDER BY clause in the SELECT statement when you create the DataAdapter object.
D. Set the RowFilter property of the DataView object to CustomerID.
Answer: A
4. You develop a Windows-based order entry application. The application uses a DataSet object named customerDataSet to manage client data while users edit and update customer records. The DataSet object contains a DataTable object named creditAuthorizationDataTable. This object contains a field named MaxCredit, which specifies the credit limit for each customer.
Customer credit limits cannot exceed $20,000. Therefore, your application must verify that users do not enter a larger amount in MaxCredit. If a user does so, the user must be notified, and the error must be corrected, before any changes are stored permanently in the database.
You create a procedure named OnRowChanged. This procedure sets the DataTable.Row.RowError property for each row that includes an incorrect credit limit. OnRowChanged will run each time a user changes data in a row. OnRowChanged contains the following code segment:
Before updating the database, your application must identify and correct all rows that are marked as having an error. Which code segment should you use?
A. For Each myRow In _ creditAuthorization
¡¡DataTable.GetErrors()
MessageBox.Show("CustID = " & _
myRow("CustID").ToString() & " " & _
¡¡"Error = " & myRow.RowError)
¡¡Next
¡¡B. For Each myRow In _
¡¡CreditAuthorization
¡¡DataTable.HasErrors()
¡¡MessageBox.Show("CustID = " & _
¡¡myRow("CustID").ToString() & " " & _
¡¡"Error = " & myRow.RowError)
¡¡Next
¡¡C. Dim vw As DataView = New DataView( _
¡¡customerDataSet.Tables("CreditAuthorization"), _
¡¡DataViewRowState.ModifiedCurrent) MessageBox.Show("CustID = " & vw("CustID") _
¡¡.ToString() & " Error"
¡¡D. Dim vw As DataView = New DataView( _
¡¡customerDataSet.Tables("CreditAuthorization"), _
¡¡DataViewRowState.ModifiedOriginal)
¡¡MessageBox.Show("CustID = " & vw("CustID") _
¡¡.ToString() & " Error"
Answer: A
5. You use Visual Studio .NET to create a Windows-based application. On the main application form, you create a TextBox control named textConnectionString. Users can enter a database connection string in this box to access customized data from any database in your company.
You also create a Help file to assist users in creating connection strings. The Help file will reside on your company intranet.
Your application must load the Help file in a new browser window when the user presses the F1 key, but only if textConnectionString has focus. You must create this functionality by using the minimum amount of code.
In which event should you write the code to display the Help file?
A. textConnectionString_KeyPress
B. textConnectionString_KeyDown
C. textConnectionString_KeyUp
D. textConnectionString_GiveFeedback
E. textConnectionString_HelpRequested
Answer: E
6. Your development team is creating an accounting application for your company. Your team uses Visual Studio .NET to write code, and it stores new code immediately by using Microsoft Visual SourceSafe.
You develop a component that uses classes created by another developer on your team. You need to perform unit testing on your component to ensure that it functions properly. However, the classes used by your component are checked out by another developer and are incomplete.
You need to perform unit testing as soon as possible. You must not cause any loss of time or resources to your development team.
What should you do?
A. Get the latest version of the classes used by your component. Write new code in the classes to ensure that they behave in the expected manner. Perform unit testing of the component against your revised version of the classes.
B. Get the latest version of the classes used by your component. Begin your unit test. When you encounter areas of the called classes that are not functioning properly, comment out that portion of the code in your component. Complete the unit test when the classes are checked in.
C. Create classes that simulate the classes used by your component. Ensure that the simulated classes accept and return parameters that match those of the current version of the classes.
D. Wait until the classes used by your component are completed. Perform your unit test with the completed classes.
Answer: C
7. You develop a kiosk application that enables users to register for an e-mail account in your domain. Your application contains two TextBox controls named textName and textEmail.
Your application is designed to supply the value of textEmail automatically. When a user enters a name in textName, an e-mail address is automatically assigned and entered in textEmail. The ReadOnly property of textEmail is set to True.
Your database will store each user's name. It can hold a maximum of 100 characters for each name. However, the database can hold a maximum of only 34 characters for each e-mail address. This limitation allows 14 characters for your domain, @proseware.com, and 20 additional characters for the user's name.
If a user enters a name longer than 20 characters, the resulting e-mail address will contain more characters than the database allows. You cannot make any changes to the database schema.
You enter the following code segment in the Leave event handler of textName:
textEmail.Text = textName.Replace(" ",".") _ &
"@proseware.com"
Now you must ensure that the automatic e-mail address is no longer than 34 characters. You want to accomplish this goal by writing the minimum amount of code and without affecting other fields in the database.
What should you do?
A. Set the textName.Size property to "1,20".
B. Set textEmail.Size property to "1,34".
C. Set textName.AutoSize property to True.
D. Set textEmail.AutoSize property to True.
E. Set textName.MaxLength property to 20.
F. Set textEmail.MaxLength property to 34.
G. Change the code in textName_Leave to ensure that only the first 20 characters of textName.Text are used.
H. Use an ErrorProvider control to prompt for a revision if a user enters a name longer than 20 characters.
Answer: G
8. You develop an application that will be sold commercially. You create a Visual Studio .NET setup project to distribute the application. You must ensure that each user accepts your license agreement before installation occurs.

B. Open the user interface designer for your setup project. Select the Welcome dialog box from the Start object and add your license agreement to the CopyrightWarning property.
C. Save your license agreement in Rich Text Format and add the file to your setup project. Open the property pages for the setup project and set the Certificate file to the name of your Rich Text file.
D. Save your license agreement in Rich Text Format and add the file to your setup project. Open the user interface designer for the setup project. From the Start object, select the License Agreement dialog box and set the LicenseFile property to the name of your Rich Text file.
Answer: D
9. You use Visual Studio .NET to create an accounting application. Within this application, you are debugging a function named CreditCardValidate. This function contains several dozen variables and objects. One of the variables is named bValidationStatus.
You create a breakpoint at the top of CreditCardValidate and run the application within the Visual Studio .NET IDE. As you step through the code in CreditCardValidate, you need to view the contents of the bValidationStatus variable. However, you want to avoid seeing the contents of the other variables and objects in the function. You also need to complete the debugging process as quickly as possible.
What should you do?
A. Open the Locals window.
B. From the Command window, print the contents of bValidationStatus by using bValidationStatus.
