Реестр

Всезнающий All!
Может кто подскажет, как работать с реестром?
Надо записать ветку и прочитать? На С, Delphi
знаю, а с VB не работал, но очень надо!

а при чём тут C,Delphi и VB ?
стандартные API функции работы с реестром работают в любом компиляторе.

Как записать\прочитать ключ в реестр

Использование:
sUser = RegGetValue(HKEY_LOCAL_MACHINE, "Software\Microsoft\Windows\CurrentVersion", "RegisteredOwner")
RegSetValue HKEY_LOCAL_MACHINE, "Software\Microsoft\Windows\CurrentVersion", "RegisteredOwner", "Darth Vader"
