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.
