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])

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.

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.

Note Note:

The REG_MULTI_SZ type is not supported for the RegWrite method.

Tip 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.

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

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\"
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\\");
