RegWrite Method

Creates a new key, adds another value-name to an existing key (and assigns it a value), or changes the value of an existing value-name.

object.RegWrite(strName, anyValue [,strType])

Arguments

object: WshShell object.
strName: String value indicating the key-name, value-name, or value you want to create, add, or change.
anyValue: The name of the new key you want to create, the name of the value you want to add to an existing key, or the new value you want to assign to an existing value-name.
strType: Optional. String value indicating the value's data type.

Remarks

Specify a key-name by ending strName with a final backslash. Do not include a final backslash to specify a value name. The RegWrite method automatically converts the parameter anyValue to either a string or an integer. The value of strType determines its data type (either a string or an integer). The options for strType are listed in the following table.

Converted to	strType
String	REG_SZ
String	REG_EXPAND_SZ
Integer	REG_DWORD
Integer	REG_BINARY

Note The REG_MULTI_SZ type is not supported for the RegWrite method.

Tip RegWrite will write at most one DWORD to a REG_BINARY value. Larger values are not supported with this method.

Fully qualified key-names and value-names are prefixed with a root key. You may use abbreviated versions of root key names with the RegWrite method. The five root keys are listed in the following table.

Root key Name	Abbreviation
HKEY_CURRENT_USER	HKCU
HKEY_LOCAL_MACHINE	HKLM
HKEY_CLASSES_ROOT	HKCR
HKEY_USERS	HKEY_USERS
HKEY_CURRENT_CONFIG	HKEY_CURRENT_CONFIG

The four possible data types you can specify with strType are listed in the following table.

Type	Description	In the Form of
REG_SZ	A string	A string
REG_DWORD	A number	An integer
REG_BINARY	A binary value	An integer
REG_EXPAND_SZ	An expandable string (e.g., "%windir%\\calc.exe")	A string

Example

The following code creates a key and two values, reads them, and deletes them.

[VBScript]

Dim WshShell, bKey
Set WshShell = WScript.CreateObject("WScript.Shell")

WshShell.RegWrite "HKCU\Software\ACME\FortuneTeller\", 1, "REG_BINARY"
WshShell.RegWrite "HKCU\Software\ACME\FortuneTeller\MindReader", "Goocher!", "REG_SZ"

bKey = WshShell.RegRead("HKCU\Software\ACME\FortuneTeller\")
WScript.Echo WshShell.RegRead("HKCU\Software\ACME\FortuneTeller\MindReader")

WshShell.RegDelete "HKCU\Software\ACME\FortuneTeller\MindReader"
WshShell.RegDelete "HKCU\Software\ACME\FortuneTeller\"
WshShell.RegDelete "HKCU\Software\ACME\"

[JScript]

var WshShell = WScript.CreateObject("WScript.Shell");

WshShell.RegWrite ("HKCU\\Software\\ACME\\FortuneTeller\\", 1, "REG_BINARY");
WshShell.RegWrite ("HKCU\\Software\\ACME\\FortuneTeller\\MindReader", "Goocher!", "REG_SZ");

var bKey =    WshShell.RegRead ("HKCU\\Software\\ACME\\FortuneTeller\\");
WScript.Echo (WshShell.RegRead ("HKCU\\Software\\ACME\\FortuneTeller\\MindReader"));

WshShell.RegDelete ("HKCU\\Software\\ACME\\FortuneTeller\\MindReader");
WshShell.RegDelete ("HKCU\\Software\\ACME\\FortuneTeller\\");
WshShell.RegDelete ("HKCU\\Software\\ACME\\");
