1. You need to write a code segment that will add a string named strConn to the connection string section of the application configuration file. Which code segment should you use?
A. System::Configuration::Configuration^ myConfig = ConfigurationManager::OpenExeConfiguration( ConfigurationUserLevel::None);myConfig->ConnectionStrings->ConnectionStrings->Add( gcnew ConnectionStringSettings("ConnStr1", strConn));myConfig->Save();
B. System::Configuration::Configuration^ myConfig = ConfigurationManager::OpenExeConfiguration( ConfigurationUserLevel::None);myConfig->ConnectionStrings->ConnectionStrings->Add( gcnew ConnectionStringSettings("ConnStr1", strConn));ConfigurationManager::RefreshSection("ConnectionStrings");
C. ConfigurationManager::ConnectionStrings::Add( gcnew ConnectionStringSettings("ConnStr1", strConn));ConfigurationManager::RefreshSection("ConnectionStrings");
D. ConfigurationManager::ConnectionStrings::Add( gcnew ConnectionStringSettings("ConnStr1", strConn));System::Configuration::Configuration^ myConfig = ConfigurationManager::OpenExeConfiguration( ConfigurationUserLevel::None);myConfig->Save();
Answer: A

2. You create an application to send a message by e-mail. An SMTP server is available on the local subnet. The SMTP server is named smtp.contoso.com. To test the application, you use a source address, me@contoso.com, and a target address, you@contoso.com. You need to transmit the e-mail message. Which code segment should you use?
A. MailAddress addrFrom("me@contoso.com", "Me");MailAddress addrTo("you@contoso.com", "You");MailMessage message(%addrFrom, %addrTo);message.Subject = "Greetings!";message.Body = "Test";message.Dispose();
B. String^ strSmtpClient = "smtp.contoso.com";String^ strFrom = "me@contoso.com";String^ strTo = "you@contoso.com";String^ strSubject = "Greetings!";String^ strBody = "Test";MailMessage msg(strFrom, strTo, strSubject, strSmtpClient);
C. MailAddress addrFrom("me@contoso.com");MailAddress addrTo("you@contoso.com");MailMessage message(%addrFrom, %addrTo);message.Subject = "Greetings!";message.Body = "Test";SmtpClient client("smtp.contoso.com");client.Send(%message);
D. MailAddress^ addrFrom = gcnew MailAddress("me@contoso.com", "Me");MailAddress^ addrTo = gcnew MailAddress("you@contoso.com", "You");MailMessage^ message = gcnew MailMessage(addrFrom, addrTo);message->Subject = "Greetings!";message->Body = "Test";SocketInformation info;Socket^ client = gcnew Socket(info);System::Text::ASCIIEncoding^ enc = gcnew System::Text::ASCIIEncoding();array<unsigned char>^ msgBytes = enc->GetBytes(message->ToString());client->Send(msgBytes);
Answer: C

3. You are developing a utility screen for a new client application. The utility screen displays a thermometer that conveys the current status of processes being carried out by the application. You need to draw a rectangle on the screen to serve as the background of the thermometer as shown in the exhibit. The rectangle must be filled with gradient shading. (Click the Exhibit button.) Which code segment should you choose?
A. Rectangle^ rectangle = gcnew Rectangle(10, 10, 450, 25); LinearGradientBrush^ rectangleBrush = gcnew LinearGradientBrush(rectangle, Color::AliceBlue, Color::CornflowerBlue, LinearGradientMode::ForwardDiagonal); Pen^ rectanglePen = gcnew Pen(rectangleBrush); Graphics^ g = this->CreateGraphics(); g->DrawRectangle(rectanglePen, rectangle);
B. Rectangle^ rectangle = gcnew Rectangle(10, 10, 450, 25); LinearGradientBrush^ rectangleBrush = gcnew LinearGradientBrush(rectangle, Color::AliceBlue, Color::CornflowerBlue, LinearGradientMode::ForwardDiagonal); Pen^ rectanglePen = gcnew Pen(rectangleBrush); Graphics^ g = this->CreateGraphics(); g->FillRectangle(rectangleBrush, rectangle);
C. RectangleF^ rectangle = gcnew RectangleF(10f, 10f, 450f, 25f); array<Point^>^ points = gcnew array<Point^>^ {gcnew Point(0, 0), gcnew Point(110, 145)}; LinearGradientBrush^ rectangleBrush = gcnew LinearGradientBrush(rectangle, Color::AliceBlue, Color::CornflowerBlue, LinearGradientMode::ForwardDiagonal); Pen^ rectanglePen = gcnew Pen(rectangleBrush); Graphics^ g = this->CreateGraphics(); g->DrawPolygon(rectanglePen, points);
D. RectangleF^ rectangle = gcnew RectangleF(10f, 10f, 450f, 25f); SolidBrush^ rectangleBrush = gcnew SolidBrush(Color::AliceBlue); Pen^ rectanglePen = gcnew Pen(rectangleBrush); Graphics^ g = this->CreateGraphics(); g->DrawRectangle(rectangleBrush, rectangle);
Answer: B

4. You are developing an application that will deploy by using ClickOnce. You need to test if the application executes properly. You need to write a method that returns the object, which prompts the user to install a ClickOnce application. Which code segment should you use?
A. return ApplicationSecurityManager::ApplicationTrustManager;
B. return AppDomain::CurrentDomain::ApplicationTrust;
C. return gcnew HostSecurityManager();
D. return SecurityManager::PolicyHierarchy();
Answer: A

5. You are using the Microsoft Visual Studio 2005 IDE to examine the output of a method that returns a string. You assign the output of the method to a string variable named fName.
You need to write a code segment that prints the following on a single line
The message: "Test Failed: "
The value of fName if the value of fName does not equal "John"
You also need to ensure that the code segment simultaneously facilitates uninterrupted execution of the application. Which code segment should you use?
A. Debug::Assert(fName == "John", "Test Failed: ", fName);
B. Debug::WriteLineIf(fName != "John", fName, "Test Failed");
C. if (fName != "John") { Debug::Print("Test Failed: "); Debug::Print(fName);}
D. if (fName != "John") { Debug::WriteLine("Test Failed: "); Debug::WriteLine(fName);}
Answer: B
