1. Create the menu command; see Creating Menus or Menu Items.

2. Create the dialog box; see Starting the Dialog Editor.

3. Add a class for your dialog box. See Adding a Class for more information.

4. In Class View, select the document class (CDisplayDialogDoc). In the Properties window, click the Events button. Double-click the ID of the menu command (ID_VIEW_TEST) in the left pane of the Properties window and select Command. In the right pane, click the down arrow and select <Add> OnViewTest.

   If you added the menu command to the mainframe of an MDI application, select the application class (CDisplayDialogApp) instead.

5. Add the following include statement to CDisplayDialogDoc.cpp (or CDisplayDialogApp.cpp) after the existing include statements:

   Copy

   #include "TestDialog.h"
   

6. Add the following code to OnViewTest to implement the function:

   Copy

   CTestDialog testdlg;
   testdlg.DoModal();
   

1. Do the first four steps to display a modal dialog box, except select the view class (CDisplayDialogView) in step 4.

2. Edit DisplayDialogView.h:

   • Declare the dialog box class preceding the first class declaration:

     Copy

     class CTestDialog;
     

   • Declare a pointer to the dialog box after the Attributes public section:

     Copy

     CTestDialog* ptestdlg;
     

3. Edit DisplayDialogView.cpp:

   • Add the following include statement after the existing include statements:

     Copy

     #include "TestDialog.h"
     

   • Add the following code to the constructor:

     Copy

     ptestdlg = NULL;
     

   • Add the following code to the destructor:

     Copy

     delete ptestdlg;
     

   • Add the following code to OnViewTest to implement the function:

     Copy

     ptestdlg = new CTestDialog(this);
     ptestdlg ->Create(CTestDialog::IDD,this);
     ptestdlg ->ShowWindow(SW_SHOW);
