CWizardPage - an MFC Convenience Class for Wizard Dialogs

Environment: VC++ 6

In one of my last projects I had to use several wizard dialogs, meaning that I had CPropertyPage objects within a CPropertySheet and set the style to wizard mode before calling DoModal, e.g.

   dlg.SetWizardMode();
   if ( dlg.DoModal() == ID_WIZFINISH )
      ; //do something appropriate

It felt quite painful to override every page's OnSetActive() method in order to show or hide the BACK, NEXT, FINISH and other buttons, so I did put all this into a tiny yet handy class. The class, CWizardPage, derives from CPropertyPage and is quite easy to use: Simply design your property page's dialog resource as you always do and create a CPropertyPage derived class with VC++'s class wizard.

Now include the header via

   #include "WizardPage.h"

into your class's header file.

Replace every occurance of the word "CPropertyPage" with "CWizardPage".

Now supply your page's constructor with a parameter ( SheetPos posPositionOnSheet = Middle ) that designates the page's position in the wizard and change the call to the base class constructor to my class's like in

   CYourPage::CYourPage( SheetPos posPositionOnSheet ) :
      CWizardPage( posPositionOnSheet, CYourPage::IDD )
   {}

Note: You HAVE to supply the default value as MFC requires a standard constructor for your class. At the place where you use your wizard you have to supply this parameter when constructing your pages like in

   CYourPage pageFirst( CWizardPage::First );
   CYourPage pageSecond( CWizardPage::Middle );
   CYourPage pageThird( CWizardPage::Middle );
   CYourPage pageFourth( CWizardPage::Last );

where the value CWizardPage::Only means that you have a degenerated wizard with only one page, i.e. the Back button is grayed and the Finish button is shown.

"En passant" my class corrects a known MFC bug by calling UpdateData() when you click the Finish button.

I hope that some of you find this class useful. If so, I'd like to hear about your experience with it as well as any bug reports and suggestions for future versions.
