RegistryGet

PowerScript function

Description

Gets a value from the Windows system registry.

Syntax

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

  • RegLongLong! — A 64-bit number which is the longlong
    type ranging from 0 – 9,223,372,036,854,775,807, because the
    registry key value cannot accept a negative 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.

Return value

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.

Examples

This statement obtains the value for the name Title and stores it in
the string ls_titlefont:

This statement obtains the value for the name NameOfEntryNum and
stores it in the long ul_num:
