SetDWORDValue method of the StdRegProv class

The SetDWORDValue method sets the data value for a named value whose data type is REG_DWORD.

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

Syntax

uint32 SetDWORDValue(
  [in]  uint32 hDefKey = HKEY_LOCAL_MACHINE,
  [in]  string sSubKeyName,
  [in]  string sValueName,
  [in]  uint32 uValue
);

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.

uValue [in]

A DWORD data value.

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 create HKEY_LOCAL_MACHINE\SOFTWARE\NewKey\Example DWORD Value and write a value of type REG_DWORD to it. If NewKey already exists then the value is added to it. You can use a registry editor such as regedt32 to view the results of the script.

const HKEY_LOCAL_MACHINE = &H80000002
strComputer = "."
Set oReg=GetObject( _
    "winmgmts:{impersonationLevel=impersonate}!\\" &_ 
    strComputer & "\root\default:StdRegProv")
strKeyPath = "SOFTWARE\NewKey"
strValueName = "Example DWORD Value"
oReg.SetDWORDValue _ 
    HKEY_LOCAL_MACHINE,strKeyPath,strValueName,250
If Err = 0 Then
   oReg.GetDWORDValue _
       HKEY_LOCAL_MACHINE,strKeyPath,strValueName,dwValue
   WScript.Echo _
       "HKEY_LOCAL_MACHINE\SOFTWARE\NewKey\Example DWORD Value " _
      & "contains " & dwValue
Else 
   WScript.Echo "Error in creating key" & _
       " and DWORD value = " & Err.Number
End If
