#define	SAVE_PREFS_TO_REGISTRY
Functions
BOOL	InitRegistry ()
	In the debug version makes sure the registry contains all the items the installed normally puts in there. Also gets the handle to the key where app state information is stored. Under Win32s does nothing.
BOOL	DeInitRegistry ()
	Shuts down the Camelot registry system, releasing any keys it holds.
HKEY	CreateRegKey (HKEY hKey, LPCTSTR lpcszSubKey, LPTSTR lpszClass=NULL)
	Creates a new subkey(s) under the given key. Returns NULL if something goes wrong.
HKEY	OpenRegKey (HKEY hKey, LPCTSTR lpcszSubKey)
	Opens a registry sub-key without creating it if it doesn't exist.
HKEY	OpenRegKeyReadOnly (HKEY hKey, LPCTSTR lpcszSubKey)
	Opens a registry sub-key without creating it if it doesn't exist.
BOOL	CloseRegKey (HKEY hKey)
	Closes a previously-opened handle to a registry key.
BOOL	GetRegValue (HKEY hKey, LPTSTR szValueName, LPDWORD pdwType, LPVOID pvBuf, LPDWORD pdwBufSize)
	Retrives a named value from a registry (sub)key.
BOOL	SetRegValue (HKEY hKey, LPCTSTR lpcszValueName, DWORD dwType, const VOID *pcData, DWORD cbData)
	Write the given value to the given key.
BOOL	SetRegDword (HKEY hKey, LPCTSTR lpcszValueName, DWORD Value)
	Write the given value to the given key.
BOOL	SetRegInt (HKEY hKey, LPCTSTR lpcszValueName, INT32 Value)
	Write the given value to the given key.
BOOL	SetRegBool (HKEY hKey, LPCTSTR lpcszValueName, BOOL Value)
	Write the given value to the given key.
BOOL	SetRegString (HKEY hKey, LPCTSTR lpcszValueName, String_256 *str)
	Write the given string to the given key.
BOOL	SetRegString (HKEY hKey, LPCTSTR lpcszValueName, TCHAR *str)
	Write the given string to the given key.
INT32	GetRegInt (HKEY hKey, LPCTSTR szValueName)
	Retrieves an INT32 value form the registry.
BOOL	GetRegBool (HKEY hKey, LPCTSTR szValueName)
	Retrieves a bool value form the registry.
DWORD	GetRegDword (HKEY hKey, LPCTSTR szValueName)
	Retrieves a DWORD value form the registry.
BOOL	GetRegString (HKEY hKey, LPCTSTR szValueName, String_256 *pOut)
	Retrieves a string from the registry. If you need more control over errors you should use the general GetRegValue function.
BOOL	GetRegString (HKEY hKey, LPCTSTR szValueName, TCHAR *str, UINT32 str_len=256)
	Retrieves a string from the registry. If you need more control over errors you should use the general GetRegValue function.
BOOL	DeleteRegKey (HKEY hKey, LPCTSTR szSubKey)
	Deletes a sub-key from the registry. To be compatible with Windows NT you may only delete a sub-key that has no sub-keys itself.
BOOL	DeleteRegKeyAndSubKeys (HKEY hKey, LPCTSTR szSubKey)
	Deletes a sub-key and all the sub- keys of that from the registry. This is to be compatible with Windows NT as this can only delete a sub-key that has no sub-keys itself. It assumes that there are only sub-keys of the specified one i.e. it does not recursively delete the sub-keys.
String_256	GetProgramNameRegistryKey ()
	Returns the name that should be used as the key when accessing the registry. It should be mapped into HKEY_CURRENT_USER as the base by the OS. Used in CCamApp::InitPreferencesFilename() in the SetRegistryKey so that we load and save data out to the registry instead of to ini files.
BOOL	CheckForRegistryEntry (TCHAR *SubKeyName)
BOOL	ConvertCLSIDToString (const CLSID &ID, StringBase *const pString)
	Converts a CLSID to a StringBase (39 characters if you've got it).
Registry *	GetLocalRegistry ()
	Provides a proper interface to Registries and stuff.
Variables
TCHAR	szCamelotAppRegistryID []
TCHAR	szCamelotExePath [_MAX_PATH]
HKEY	hAppStateRegKey
const String_8	NullString
typedef	CATID
	Allows us to whizz through a component category picking out all the registry entries for it. At present, this class is only ever associated with the local registry.
