Property Sheet Title and Page Labels
You specify the title of a property sheet in the PROPSHEETHEADER structure used to create the property sheet. If the dwFlags member includes the PSH_PROPTITLE value, the property sheet adds the "Properties for" prefix to the specified title string. An application can change the title after a property sheet is created by using the PSM_SETTITLE message.
By default, a property sheet uses the name string specified in the dialog box template as the label for a page. You can override the name string by including the PSP_USETITLE value in the dwFlags member of the PROPSHEETPAGE structure that defines the page. When PSP_USETITLE is specified, the pszTitle member must contain the address of the label string for the page.
