#220 - RegEdit

Ett litet program som man kan ställa in tre saker i registret (Än så länge), OBS, Innan du testar så ha detta i bakhuvudet, DU kan bara testa programet 2 gånger, sedan kan du ej trycke på "Vekställ"

Jag är på chaten idag den 02-04-19, så du kan fråga mej så får du reda på hur man "Resetar" programet så du kan pröva igen:)

SÅ här är det gjort:

I Modul:

Public Const HKEY_CLASSES_ROOT = &H80000000
Public Const HKEY_CURRENT_USER = &H80000001
Public Const HKEY_LOCAL_MACHINE = &H80000002
Public Const HKEY_USERS = &H80000003
Public Const HKEY_PERFORMANCE_DATA = &H80000004
Public Const ERROR_SUCCESS = 0&

End Function


Sen använder du följade kommandon för:

Spara en nyckel:
Call savestring(Valfri nyckel, "Undernyckel", "Ange namn", "Ange värde här"

För att hämta ett värde:

strString = getstring(Nyckel, "Undernyckel", "Ange namn")
