QUESTION NO: 49(part 2)
You are debugging a financial application for TKGreenBack Inc. You notice that when blnOverdue
changes the total charge is incorrect. You want execution to pause at a breakpoint if the value of a
variable has changed.
Which of the following actions should you perform to stop execution? (Select the best choice.)
A. Set an assertion.
B. Set a watch for the variable.
C. Set a watch for the method which contains the variable.
D. Use a Stop statement.
E. Stop execution of the code immediately.
F. Set a breakpoint with a condition.
Answer: D

Breakpoints are used to break execution while code is running in the Visual Studio .NET IDE. You can set
conditions on breakpoints so that execution will pause only if a given condition is met. One of the conditions
that you can set is whether a variable's value has changed. If the value has changed since the last time that
the breakpoint was encountered, execution will stop on the line of code with the breakpoint that contains the
variable. Setting a watch allows you to view the value of a variable as code executes.
А вот мне кажется ответ F . Причем они здесь дали ответ B , а объяснения на ответ выглядят, как-будто они объясняют про ответ F .

You use Visual Studio .NET to create a Windows Form named TestKingForm. You add a custom
control named BarGraph, which displays numerical data. You create a second custom control named
DataBar. Each instance of DataBar represents one data value in BarGraph.
BarGraph retrieves its data from a Microsoft SQL Server database. For each data value that it
retrieves, a new instance of DataBar is added to BarGraph. BarGraph also includes a Label control
named DataBarCount, which displays the number of DataBar controls currently contained by
BarGraph.
You must add code to one of your custom controls to ensure that DataBarCount is always updated
with the correct value.
What are two possible ways to achieve this goal? (Each correct answer presents a complete solution.
Choose two)
A. Add the following code segment to the ControlAdded event handler for DataBar:
this.DataBarCount.Text = this.Controls.Count;
B. Add the following code segment to the ControlAdded event handler for DataBar:
this.DataBarCount.Text = Parent.Controls.Count;
C. Add the following code segment to the ControlAdded event handler for BarGraph:
DataBarCount.Text = this.Controls.Count;
D. Add the following code segment to the constructor for BarGraph:
this.Parent.DataBarCount.Text = this.Controls.Count;
E. Add the following code segment to the constructor for DataBar:
this.Parent.DataBarCount.Text = this.Controls.Count;
F. Add the following code segment to the AddDataPoint method of BarGraph:
DataBarCount.Text = this.Controls.Count;
Answer: C, E
Почему E? Строкой this.Parent.DataBarCount.Text = this.Controls.Count; мы обращаемся к родителю, вытаскиваем у него DataBarCount.Text и почему то устанавливаем равным кол-ву элементов в коллекции дочернего компонента.
А у дочернего компонента эта коллекция пуста. Поэтому как мне кажется в случае ответа E будет кол-во будет все время установлено все время в 0.

You use Visual Studio .NET to create an accounting application called TestKingAccounting, which
includes a function named CreditCardValidate. This function contains several dozen variables and
objects.
To debug CreditCardValidate, you create a breakpoint at the top of the function. You run the
accounting application within the Visual Studio .NET IDE and step though the code for
CreditCardValidate. You need to examine the contents of the variables and objects in scope on each
line of code. However, you want to avoid seeing the contents of all variables and objects within
CreditCardValidate. You also need to complete the debugging process as quickly as possible.
What should you do?
A. Use the Autos window.
B. Use the Locals window.
C. Use the QuickWatch window.
D. From the Command window, print the contents of each variable that you want to examine by using
the following code segment:

You use Visual Studio .NET to develop a Microsoft Windows-based application. Your application
contains a form named CustomerForm, which includes the following design-time controls:
• SQLConnection object named TestKingConnection
• SQLDataAdapter object named TestKingDataAdapter
• DataSet object named CustomerDataSet
• Five TextBox controls to hold the values exposed by CustomerDataSet
• Button control named saveButton
At design time you set the DataBindings properties of each TextBox control to the appropriate column
in the DataTable object of CustomerDataSet.
When the application runs, users must be able to edit the information displayed in the text boxes. All
user changes must be saved to the appropriate database when saveButton is executed. The event
handler for saveButton includes the following code segment:
TestKingDataAdapter.Update(CustomerDataSet);
You test the application. However, saveButton fails to save any values edited in the text boxes.
You need to correct this problem.
What should your application do?

A. Call the InsertCommand method of TestKingDataAdapter.
B. CALL THE Update method of TestKingDataAdapter and pass in TestKingConnection.
C. Before calling the Update method, ensure that a row position change occurs in CustomerDataSet.
D. Reestablish the database connection by calling the Open method of TestKingConnection.
Answer: B
Дело в том, что такой перегруженной ф-ии, берущей такие параметры нет.
Удивительно, что в TestKing'e они не подумали, прежде чем написать такую окалесицу.
Вообще все варианты мне кажется не правильными, но из-за того, что на голосовании большинство ответили C, буду все таки за него.

You develop a Windows-based order entry application TestKingEntry by using Visual Studio .NET.
TestKingEntry includes a DataSet object. When a customer order exceeds the number of items
currently available in stock, TestKingEntry must create two separate entries in a database.
The first entry specifies the total number of items in the customer order, as well as the number of
items that can be supplied immediately from available stock. The second entry records backorder
information, and specifies the number of items that must be supplied when new stock becomes
available.
Backorder processing is handled by a separate component. You must ensure that all order
information in the DataSet object is captured and passed to this component. To do so, you need to
create a new DataSet object.
Which method should you use?
A. DataSet.Clone
B. DataSet.Copy
C. DataSet.Merge
D. DataSet.GetChanges
Answer: D
Здесь мне кажется ответ правильным - B, но почему то многие, в том числе и TestKing отвечают D. Некоторые на флрумах этот объясняют, как вопрос с подвохом: типо когда здесь говорят в вопросе все данные имеют ввиду измененные.

You develop a Windows-based application to manage inventory for TestKing inc. The application
calls a Microsoft SQL Server stored procedure named sp_UpdatePrices.
sp_UpdateTKPrices performs a SQL UPDATE statement that increases prices for selected items in an
inventory table. It returns an output parameter named @totalprice and a result set that contains all of
the records that were updated. @totalprice contains the sum of the prices of all items that were
updated.
You implement a SqlCommand object that executes sp_UpdateTKPrices and returns the results to a
SqlDataReader object. The SqlDataReader object gives you access to the data in the result set. Which
is displayed in a list box on your Windows Form.
The value of @totalprice must also be displayed in a text box on your Windows Form. You need to
write code that will retrieve this value.
Which code segment should you use?
A. while (reader.Read() {
TextBox1.Text =
com.Parameters[“@totalprice”].Value.ToString();
}
reader.Close();
B. do {
TextBox1.Text =
com.Parameters[“@totalprice”].Value.ToString();
}
while (reader.Read());
reader.Close();
C. TextBox1.Text =
com.Parameters[“@totalprice”].Value.ToString();
reader.Close();
D. reader.Close();
TextBox1.Text =
com.Parameters[“@totalprice”].Value.ToString();
Answer: C
Ну здесь однозначно они ошиблись. :)
Сначало надо закрыть соединение, а потом читать. Поэтому ответ D.(даже спорить нечего, потому что это неоспаримо)
