Changing The Active Tab using PageUp/PageDown

I produce a custom database application, that has some windows with lots of tabs / CPropertyPages within them. My customer wanted a way to quickly and easily change the selected tab, without using the mouse. He said "In the old DOS version we changed the current window using Page-Up and Page-Down....". Ahh those were the days! So what the customer wants, the customer gets, and here is the result : Page-Up / Page-Down will select the next / previous tab. It's so easy, it's simple...

Basically sub-class your CPropertySheet. Then using the class wizard, create the PreTranslateMessage() function, and insert the text below...

if (pMsg->message == WM_KEYUP && pMsg->wParam == VK_NEXT)
{
    if(GetPageCount() > 1)  // Ignore if only one CPropertyPage
    {
       if(GetActiveIndex() == 0)  //If first page active, select last page
          SetActivePage(GetPageCount() - 1);
       else
          SetActivePage(GetActiveIndex() - 1);  //else select the previous page
    }
}

if (pMsg->message == WM_KEYUP && pMsg->wParam == VK_PRIOR)
{
    if(GetPageCount() > 1)  // Ignore if only one CPropertyPage
    {
       if(GetActiveIndex() == (GetPageCount() - 1))  //If last page active, select the first page
          SetActivePage(0);
       else
          SetActivePage(GetActiveIndex() + 1);  //else select the next page
    }
}
