Kako Win XP postavlja XP style na kontrole?

Pisao sam neke programcice za Win jos pre Win XP i sada kada ih pokrenem na XP-u uz dodatni fajl ImePrograma.exe.manifest XP ume lepo da doda style i na stare programcice. Kako se to radi? Da li je komplikovano napisati skin engine sa nekim osnovim mogucnostima (bez alphablendinga, bez nepravilnih oblika prozora...)?

Sto se tice menjanja stylova postoje interesantni programcici koji to rade recimo:

TGTSoft StyleBuilder i sl ...

Zaseban skin u programu (u odnosu na ostatak sistema) je vec druga tema ...

Znam za funkcije koje iscrtavaju Win XP style, ali kako WinXP sam iscrtava komponente u programima koje sam pisao za Win98. Onda nisam ni znao za te funkcije i sigurno ih nisam koristio u programu. Samo sam u folderu gde je moj programcic ubacio Firma.exe.manifest i XP je sam sredio da kontrole imaju XP style. Uopste mi nije jasno kako to uspeva... jedino sto mi pada na pamet je da je ili subclass-ovao moje komponente ili ubacio neki WinHook koje je presretao WM_PAINT poruke i ko zna jos koje.

EKSTREMNO UPROSCENO :

ti si pozivao windows da ti iscrtava sve kontrole (i iz starih, a radis to i iz novih programa)
windows je ranije to radio preko common controls 5.xxx (stari izgled) a sada to radi tako sto ima dva common controls dll-a (5.xxx i 6.xxx) pa ako nemas manifest dobijes onaj stari (5.xxx sa starim izgledom) a ako imas manifest podmetne ti novi dll (6.xxx sa novim izgledom)

Hmmmm... mislio sam da XP to drugacije radi, ali dobro. Kako to rade drugi programi kao sto je www.windowblinds.net Oni mogu da promene izgled bilo kog programa koji koristi standardne komponente i u Win 98 i u Win XP. Nije mu bitno koja je verzija comctrls-a. Hteo bih da napravim neki jednostavan skin engine koji bi mogao da radi nesto slicno.
