Wizard Property Sheets and Pages

I made these two classes to add an often used feature to the property sheets/pages provided by the MFC. The new classes allow you, to easily skip certain pages when viewing the tabbed dialog. This is very usefull for installation or assistent wizards.

You can now also access the the property sheet from every page using the m_pPropSheet protected member.

Using the Classes

These classes work only in wizard mode, which is set by default, so there's no need to set it by hand. There's no way to use the extra functionlity of these classes while not in Wizard mode.

To use the CWizPropertyPage, just implement your pages as decendents of CPropertyPage and then use the replace functionality of the editor to exchange every CPropertyPage with CWizPropertyPage.

To skip pages, you can either disable these page directly, or tell the WizPropertySheet to disable a whole range:

	// I'm assuming that CPage1 - CPage3 are derived from
	// CWizPropertyPage
	CPage1 page1;
	CPage2 page2;
	CPage3 page3;
	CWizPropertySheet sheet;
	
	sheet.Add(page1);
	sheet.Add(page2);
	sheet.Add(page3);
	
	// Disable page 1 and 2
	page1.Enable(FALSE);	
	page2.Enable(FALSE);
	
	// Enable them via the sheet
	sheet.EnablePages(TRUE,1,2);	// NOTE: zero based index

CWizPropertySheet

This class is derived from CPropertySheet and does add a single method:
    void EnablePages(BOOL bEnable, int nStart, int nEnd = -1);
  • If bEnable is TRUE the pages get enabled, if FALSE they will be disabled
  • nStart specifies the first page to enable or disable.
  • nEnd specifies the last page to enable/ disable. If omitted, only the page with the index nStart will be changed.
All constructors are changed to set wizard mode, Add() sets a protected varible within CWizPropertyPage, so the pages know to which sheet they belong.


CWizPropertyPage

This class is derived from CPropertyPage, and adds these methods:
	BOOL Enable(BOOL bEnable=TRUE);
	BOOL IsEnabled(void);
	virtual LRESULT GetNextPage(BOOL forward = TRUE); // protected
and these data members:
    BOOL m_bEnabled; // protected CWizPropertySheet *m_pPropSheet;// protected
Use Enable() to enable a page, and Enable(FALSE) to disable a page.
IsEnabled() returns the TRUE if the pages is enabled, else FALSE is returned.

m_pPropSheet allows you to access the sheet the page got added to.
