Field “ Resource:” defines the name of resource, which corresponds the class from field “ Class Name:“.5. Window MS Visual Studio and panel Solution Explorer.After performing steps, the window of panel “ Solution Explorer” has the view as shown in Figure 9.As you see in Figure 9, there are two files “ Form2.h” and “ Form2.cpp” in the list of files. In the previously window you can see, that to three previously classes is added class CForm2. Creating a new class CForm2 and new resource IDD_FORM2We do the click on button “ Finish“. Automatically all the other fields will be filled with the exception of field “ Base class:“.In the field “ Base class:” is specified base class CDialog.The name of resource is set to IDD_FORM2.Header file and implementation file are named “ Form2.h” and “ Form2.cpp“.Fig. To set values of fields, you need enter text “ CForm2” in the field “ Class Name:“. IDD_MFC_APP_DIALOG – resource of main window of application.To call a needed resource, you need do the double click by mouse. IDD_FORM2 – resource of newly created dialog box IDD_ABOUTBOX – resource of dialog box of About window Calling the resources names list of applicationAs result, we get the list of available resources: To do it, in Solution Explorer, you need do the double mouse click on the file “ MFCApp.rc” of tab “ Resources” (Fig. Calling the dialog box of class CForm2 as resource.To begin forming new dialog box (class CForm2) you need to call it as a resource. The event programming of click at the button “ Form2” of main window of application.Using “ Solution Explorer” and resource file “ MFCApp.rc” (see p.7) we are proceeding to resource IDD_MFCAPP_DIALOG of main window of application (Fig.12).In the “ Properties” window we select the button with identifier IDC_BUTTON1.

The selection of event BN_CLICKED and calling the handling event OnBnClickedButton1As a result, the window of file “MFCAppDlg.cpp” with the selected code of handling event OnBnClickedButton1 will be opened. Then we select the button of selection of drop-down menu and select “ OnBnClickedButton1” (Fig. List of events from tab “ Control Events” of control IDC_BUTTON1In the list of events we find the event named BN_CLICKED.
