RegistryGet

Description

Gets a value from the Windows system registry.

Syntax

RegistryGet ( key, valuename, { valuetype }, valuevariable )

Argument	Description
key	A string whose value names the key in the system registry whose value you want. To uniquely identify a key, specify the list of parent keys above it in the hierarchy, starting with the root key. The keys in the list are separated by backslashes.
valuename	A string containing the name of a value in the registry. Each key can have one unnamed value and several named values. For the unnamed value, specify an empty string.
valuetype	A value of the RegistryValueType enumerated datatype identifying the datatype of a value in the registry. Values are: RegString! – A null-terminated string RegExpandString! – A null-terminated string that contains unexpanded references to environment variables RegBinary! – Binary data ReguLong! – A 32-bit number ReguLongBigEndian! – A 32-bit number RegLink! – A Unicode symbolic link RegMultiString! – An unbounded array of strings
valuevariable	A variable corresponding to the datatype of valuetype in which you want to store the value obtained from the system registry for the specified key and value name.

Returns

Integer. Returns 1 if it succeeds and -1 if an error occurs. An error is returned if the datatype of valuevariable does not correspond to the datatype specified in valuetype.

Usage

Long string values (more than 2048 bytes) should be stored as files and the file name stored in the registry. For more information about keys and value names in the system registry, see RegistrySet.
