12.3.3..Property Sheets....................................................................................

To implement its functionality, the property pages are put together and kept as an entity

by an object called a property sheet. The property sheet acts as their parent. Like other

controls, we will see that the property pages must be added to a property sheet.

There is no resource to create for a property sheet. A property sheet is based on the

CPropertySheet class, which is not based on CDialog but it provides the same

functionality as dialog. Therefore, a property sheet is sometimes called, or referred to as,

a dialog box. Instead, CPropertySheet is based on the CWnd class. Therefore, to

implement your property page(s), you can simply declare a CPropertySheet variable and

use it to display the application or you can programmatically derive a class from

CPropertySheet. The CPropertySheet class is declared in the afxdlgs.h header file.

If you decide to directly use the CPropertySheet class, declare a variable for it where the

application will need to be displayed or instantiated, which could be in the

CWinApp::InitInstance() event. To display the property sheet, call its DoModal()

method. This could be done as follows:

BOOL CMyApp::InitInstance()

{

CPropertySheet MySheet;

MySheet.DoModal();

}
