as the requirements for the project, items to be tested, test deliverables, environmental needs, and so forth. A test specification document is also prepared to help the testers check the application. The test specification document lists the specifications for testing the application.

The Execution Phase

This is the final phase in the DLC of the application. After the application has been successfully tested, it needs to be distributed so that all departments in the institute have access to the project. The development team of the application has the responsibility of providing constant support in terms of installation and debugging errors, if any, to all faculty members using the application.

Coding the Application

As discussed in the previous section, the Easy Tool application comprises a number of screen elements. Before delving deep into the code behind the application, let me first explain how to create a Managed C++ application and the interface elements of the application (the menus and the toolbar). After discussing the creation of these elements, I will discuss how to programmatically add functionality to these elements.

Creating the Application

To create a Managed C++ application, follow these steps:

1.Choose File, New Project.

2.From the list of projects displayed, select Managed C++ Application and enter the name of the application. By default, the environment creates the <app name>.cpp file, the AssemblyInfo.cpp file, and the stdafx.cpp and .h files.

3.Add the required files to the project based on your requirements.

Creating the User Interface Form

In a number of instances in an application, user input has to be accepted. You can accept user input using forms and the Windows controls that are placed on these

Button Class

As previously discussed, the Button class encapsulates the functionality associated with creating and displaying a button. Table 12-2 lists the important methods of the Button class.

TextBox Class

The TextBox class is used to accept user input. Some of the important properties of the TextBox class are listed in Table 12-3.

Table 12-3 Properties of the TextBox Class

button2->Size = System::Drawing::Size(75, 23); button2->TabIndex = 6;

button2->Text = “Cancel”;

TextBox* textBox1 = new TextBox();

textBox1->Location = System::Drawing::Point(120, 36); textBox1->Text = pActiveDoc->nThinWidth.ToString(); textBox1->TabIndex = 1;

textBox1->Size = System::Drawing::Size(64, 20);

TextBox* textBox2 = new TextBox();

textBox2->Location = System::Drawing::Point(120, 76); textBox2->Text = pActiveDoc->nThickWidth.ToString(); textBox2->TabIndex = 2;

textBox2->Size = System::Drawing::Size(64, 20);

Label* label1 = new Label();

label1->Location = System::Drawing::Point(16, 36); label1->Text = “Thin Pen Width:”;

label1->Size = System::Drawing::Size(88, 16); label1->TabIndex = 3;

Label* label2 = new Label();

label2->Location = System::Drawing::Point(16, 76); label2->Text = “Thick Pen Width:”;

label2->Size = System::Drawing::Size(95, 16); label2->TabIndex = 4;

f->FormBorderStyle = FormBorderStyle::FixedDialog;

//Set the MaximizeBox to false to remove the maximize box. f->MaximizeBox = false;

//Set the MinimizeBox to false to remove the minimize box. f->MinimizeBox = false;

//Set the accept button of the form to button1.

f->AcceptButton = button1;

// Set the cancel button of the form to button2. f->CancelButton = button2;
