SetMultiStringValue method of the StdRegProv Class

Applies to: desktop apps only

The SetMultiStringValue method sets the data value for a named value whose data type is REG_MULTI_SZ.

This topic uses Managed Object Format (MOF) syntax. For more information about using this method, see Calling a Method.

Syntax

uint32 SetMultiStringValue(
  [in]  uint32 hDefKey = HKEY_LOCAL_MACHINE,
  [in]  string sSubKeyName,
  [in]  string sValueName,
  [in]  Variant sValue[]
);

Parameters

hDefKey [in]

A registry tree, also known as a hive, that contains the sSubKeyName path. The default value is HKEY_LOCAL_MACHINE.

Note that HKEY_DYN_DATA is a valid tree for computers running Windows 95 and Windows 98 only.

The following trees are defined in Winreg.h.

HKEY_CLASSES_ROOT (2147483648 (0x80000000))

HKEY_CURRENT_USER (2147483649 (0x80000001))

HKEY_LOCAL_MACHINE (2147483650 (0x80000002))

HKEY_USERS (2147483651 (0x80000003))

HKEY_CURRENT_CONFIG (2147483653 (0x80000005))

HKEY_DYN_DATA (2147483654 (0x80000006))

sSubKeyName [in]

A key that contains the named value to be set.

sValueName [in]

A named value whose data value you are setting. You can specify an existing named value (update) or a new named value (create). Specify an empty string to set the data value for the default named value.

sValue [in]

An array of string data values.

Return value

In C++, the method returns a uint32 value that is 0 (zero) if successful. If the function fails, the return value is a nonzero error code that is defined in Winerror.h. In C++, use the FormatMessage function with the FORMAT_MESSAGE_FROM_SYSTEM flag to get a generic description of the error. You can also look up return values under the WMI Error Constants.

In scripting or Visual Basic, the method returns an integer value that is 0 (zero) if successful. If the function fails, the return value is a nonzero error code that you can look up in WbemErrorEnum.

Examples

For script code examples, see WMI Tasks for Scripts and Applications and the TechNet ScriptCenter Script Repository. Other examples are in books and articles listed in Further Information.

For C++ code examples, see WMI C++ Application Examples.

The following VBScript code example shows how to write an array of new values to the REG_MULTI_SZ value that is located in HKEY_LOCAL_MACHINE\SOFTWARE\NewKey\MultiValueName.

const HKEY_LOCAL_MACHINE = &H80000002
strKeyPath = "SOFTWARE\NewKey"
MultValueName = "Example Multistring Value"
strComputer = "."
iValues = Array("string1", "string2")
Set oReg=GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & _
   strComputer & "\root\default:StdRegProv")
oReg.CreateKey HKEY_LOCAL_MACHINE,strKeyPath
oReg.SetMultiStringValue HKEY_LOCAL_MACHINE,strKeyPath,_
    MultValueName,iValues
WScript.Echo "Set registry value HKLM\SOFTWARE\NewKey\Example" _
    & " MultiString Value to string1 string 2"
