// Internal data structures for property sheet support.

//
// Sigh. Wiz97 underwent a redesign between IE4 and IE5
// so we have to treat them as two unrelated wizard styles that happen to
// have frighteningly similar names. So prsht.h contains both
// PSH_WIZARD97IE4 and PSH_WIZARD97IE5, and defines PSH_WIZARD97 to be
// the one appropriate to the version of the header file being included.
//
// We redefine PSH_WIZARD97 to mean "Any form of Wizard97",
//

// The history of PROPSHEETHEADER
//
// PROPSHEETHEADERSIZE_BETA
//
// This is the property sheet header that shipped in an early
// Win95 beta (sometime between Sep 1993 and Sep 1994, maybe M5).
//
// It is just like the shipping Win95 property sheet header,
// except that it lacks the PFNPROPSHEETCALLBACK at the end.
// We grudgingly accept it but don't publicize the fact.
//
// For some reason, we have always supported this wacky
// ancient unreleased PROPSHEETHEADER, so there's no point
// in dropping support for it now... If you think it's not
// worth retaining support for this ancient structure,
// feel free to nuke it. But you become responsible for the
// potential app compat bugs from Norton Utilities for
// Windows 95 v1.0.
//
// PROPSHEETHEADERSIZE_V1
//
// This is the property sheet header that shipped in Win95,
// NT4, and IE3. It is documented and lots of people use it.
//
// PROPSHEETHEADERSIZE_V1a
//
// This is an interim property sheet header that never shipped.
// Support for it has been broken for a long time, so I dropped
// the support altogether for IE5.
//
// PROPSHEETHEADERSIZE_V2
//
// This is the property sheet header that shipped in IE4.

// Shell32 prior to IE5 knows the internal structure of the HPROPSHEETPAGE,
// so we have to give it what it wants. (shell32\bitbuck.c, docfind2.c)
//
// Win95 Golden - Shell32 expects the HPROPSHEETPAGE to be equal to
// the lParam that is passed to the dialog proc's WM_INITDIALOG.
// No special flags are passed in the PROPSHEETPAGE to indicate
// that this assumption is being made.
//
// Win95 IE4 Integrated - Same as Win95 Golden, except that
// the shell sets the PSP_SHPAGE bit in the PROPSHEETPAGE.dwFlags
// to indicate that it wants this wacky behavior.
//
// WinNT Golden - Shell32 expects the HPROPSHEETPAGE to be equal
// to a pointer to the internal PSP structure used by WinNT golden.
// The internal PSP structure looked like a PROPSHEETPAGE, except
// that it had two fields stuck in front. (One DWORD and one pointer.)
// The NT shell passes the PSP_SHPAGE flag.
//
// WinNT IE4 Integrated - Same as WinNT Golden.
//
// Furthermore, all versions of Shell32 prior to IE5 call the internal
// CreatePage function (shell32\docfind2.c)

// --------- ------- -------------
// 95 Gold ANSI
// 95/IE4 * ANSI
// NT Gold * UNI *
// NT/IE4 * UNI *
//
// Note that Win95 Gold does not set the PSP_SHPAGE flag, so we have
// to assume that any ANSI caller might be a Win95 Gold shell32.
//
// WinNT is easier. We return the WinNT Golden UNICODE version of
// the PSP if (and only if) the PSP_SHPAGE flag is set.
//
// The PSP_SHPAGE flag has been removed from the header file so nobody
// can pass it ever again.
//
// So our structures look like this. The bracketed section is the
// the memory block passed by the app to CreatePropertySheetPage
// and whose layout cannot be altered.

// \ | |
// \+---------------+
//
// Are we confused yet? Let's try to explain.
//
// REQUIREMENT
//
// The app goo must be kept in the structure
// corresponding to the character set of the application.
//
// Notice that if the application is ANSI, then the app goo
// is kept with the ANSI version of PROPSHEETPAGE. If the
// application is UNICODE, then the app goo is kept with the
// UNICODE version of the PROPSHEETPAGE.
//
// It doesn't hurt to "accidentally" put a copy of the app goo
// on the version the app doesn't use; that just wastes memory.
//
// REQUIREMENT
//
// If a UNICODE app passed PSP_SHPAGE, then the hpage must
// point to the CLASSICPREFIX structure.
//
// To simplify matters (like HPROPSHEETPAGE validation), we
// apply this rule even if the app didn't pass PSP_SHPAGE.
//
// DESIGN
//
// If the app is ANSI and we support UNICODE, then we create
// a UNICODE copy of the ANSI property sheet structure,
// and the ANSI PROPSHEETPAGE becomes a "shadow".
// The UNICODE copy does not need to carry the app goo
// since it will never be seen by the app.
//
// REQUIREMENT
//
// If an ANSI app creates a property sheet page, then the hpage
// must point to the ANSI version of the PROPSHEETPAGE.
// (Because the app might be shell32.)
//
// >> CAUTION <<
//
// The requirements on hpages rule means that any time an hpage
// comes in from the outside world, we need to sniff it and decide
// if it's the UNICODE version or the ANSI version; if it's
// the ANSI version, then we switch the pointer to point to
// the UNICODE version instead.
//
// REMARK
//
// Internally, we use only the UNICODE version of the PROPSHEETPAGE.
// (Unless we're building Win95 ANSI-only, duh.) The ANSI version
// (the "shadow") is just for show to keep the app happy. It is
// the UNICODE version that is authoritative.
//
// Only the authoritative PROPSHEETPAGE needs to have the PAGEPREFIX,
// but we put one on both sides to simplify memory management,
// because it means that all PROPSHEETPAGEs look the same (both
// authoritative and shadow).
#define PSP_SHPAGE 0x00000200 // Ewww; see above
//
// CLASSICPREFIX
//
// This structure is allocated ahead of the PROPSHEETPAGE when we
// create an HPROPSHEETPAGE. See the diagrams above. Sometimes
// the HPROPSHEETPAGE points to this structure, sometimes it doesn't.
// See the diagrams above.
//
// This structure can never change, due to backwards compatibility
// constraints described above. (Okay, you can change it once you
// decide to drop support for versions of NT less than 5, like that'll
// ever happen.)
//

// there is no shadow copy.
