Q: How can I access the registry?
A: The ATL provides the class 'CRegKey()' containing the following members which can be used in MFC without any problems:
Code:
// Methods
CRegKey()
void Attach(HKEY hKey)
LONG Close()
LONG Create(HKEY hKeyParent,
LPCTSTR lpszKeyName,
LPTSTR lpszClass = REG_NONE,
DWORD dwOptions = REG_OPTION_NON_VOLATILE,
REGSAM samDesired = KEY_ALL_ACCESS,
LPSECURITY_ATTRIBUTES lpSecAttr = NULL,
LPDWORD lpdwDisposition = NULL)
LONG DeleteSubKey(LPCTSTR lpszSubKey)
LONG DeleteValue(LPCTSTR lpszValue)
HKEY Detach()
LONG Open(HKEY hKeyParent,
LPCTSTR lpszKeyName,
REGSAM samDesired = KEY_ALL_ACCESS)
LONG QueryValue(DWORD& dwValue, LPCTSTR lpszValueName)
LONG QueryValue(LPTSTR szValue, LPCTSTR lpszValueName, DWORD* pdwCount)
LONG RecurseDeleteKey(LPCTSTR lpszKey)
LONG SetKeyValue(LPCTSTR lpszKeyName,
LPCTSTR lpszValue,
LPCTSTR lpszValueName = NULL)
LONG SetValue(DWORD dwValue, LPCTSTR lpszValueName)
LONG SetValue(LPCTSTR lpszValue, LPCTSTR lpszValueName = NULL)
LONG SetValue(HKEY hKeyParent,
LPCTSTR lpszKeyName,
LPCTSTR lpszValue,
LPCTSTR lpszValueName = NULL)
// Operators
operator HKEY() const
