VaToolBxReadKeyValueNum

This function is used to read the numerical value (NUM_E or NUM_P format) associated with an attribute for a given key in the registry.

NUM_BIN_2	KeySet	Value describing the subset of keys stored in the registry. Two key subsets are available: HKEY_CLASSES_ROOT: value "0", HKEY_CURRENT_USER: value "1", HKEY_LOCAL_MACHINE: value "2", HKEY_CURRENT_CONFIG: value "3", HKEY_USERS: value "4".
ALPHA(n)	KeyName	Path leading to the key in which the AttributeName attribute is to be read. A path is a series of key names separated by "\" characters. Each key in the path will be a subkey of the key preceding it. The first key in the path will be the highest-level key in the specified key subset.
ALPHA(n)	AttributeName	Character string describing the attribute associated with the KeyName key .
NUM_E(Ln,NbDecimals) AttributeValue or NUM_P(Ln,NbDecimals) AttributeValue		Result variable associated with the AttributeName attribute.
NUM_BIN_2	Ln	Length of the AttributeValue parameter.
NUM_BIN_2	NbDecimals	Number of decimal places in the AttributeValue parameter.
BOOL	ReturnCode	Return code for the operation: TRUE if the operation was successful. FALSE if the key or attribute is not present in the specified subset.
