  3. Save the class and close the Class Designer.
  4. Create a class myPage2 with the code below: 
          CREATE CLASS myPage2 OF myclib AS myPage1 FROM myclib
  5. When the Class Designer appears, set the Pagecount to three.
  6. Save the class and close the Class Designer.
  7. Create a form and place each of the classes, myPage1 and myPage2, onto the form.

    NOTE: Both PageFrames are not visible.
  8. Run the Form.

    NOTE: Both the PageFrames are still not visible.
  9. Click in the area on the form where the PageFrame SubClass should be and it becomes visible.
The PageFrame SubClass, myPage2, should be visible at design and run-time.
