Question

Hi I am using WMI to change the remote registry value for USBSTOR. I want to change the value of start attribute to 4 or 3 for enabling and disabling. But the datatype for Start attribute in registry is DWORD, if i can the datatype to size it does not work . I need to keep the Datatype to DWORD. Can someone please tell me how to setDWORDValue using WMI, following is the piece of code that i tried, it worked succesfully but still the value of start field is unchanged in registry.

const uint HKEY_LOCAL_MACHINE = 0x80000002;

ManagementBaseObject methodParams = registryTask.GetMethodParameters(typeOfValue);

methodParams["hDefKey"] = HKEY_LOCAL_MACHINE;// BaseKey;
methodParams["sSubKeyName"] = @"SYSTEM\CurrentControlSet\Servic\USBSTOR";
methodParams["sValueName"] = "Start";

try
{
    methodParams["sValue"] = "3";
}
catch
{
    methodParams["uValue"] = (UInt32)Convert.ToInt32("3");
}

ManagementBaseObject exitValue = registryTask.InvokeMethod(typeOfValue, methodParams, null);

简单的解决办法使用假日。

import wmi
import win32api,_winreg

c = wmi.WMI()

# To get the binary value of particular subkey
# Please note that 0x80000002 represents HKEY_LOCAL_MACHINE 
ReturnValue, uValue = c.StdRegProv.GetBinaryValue(0x80000002,"AFD","SYSTEMCurrentControlSetServices")

# To get the list of all the subkeys available in particular key
ret, subKeys = c.StdRegProv.EnumKey (0x80000002, "SYSTEMCurrentControlSetServices")
print ret
for key in subKeys:
  print key

ReturnValue=c.StdRegProv.SetDWORDValue(0x80000002,"Type","SYSTEMCurrentControlSetServicesUSBSTOR",0x4)

#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))

是的。此处指该微软的密码:link/a>和。用你想要使用的新价值取代389,并根据需要改变关键价值:

const HKEY_LOCAL_MACHINE = &H80000002
strComputer = "."
 Set StdOut = WScript.StdOut
Set oReg=GetObject( _
    "winmgmts:{impersonationLevel=impersonate}!\" &_ 
    strComputer & "
ootdefault:StdRegProv")
strKeyPath = "SYSTEMCurrentControlSetControlTerminal ServerWinStationsRDP-Tcp"
strValueName = "PortNumber"

  Display old value
oReg.GetDWORDValue HKEY_LOCAL_MACHINE,strKeyPath,strValueName,dwValue
WScript.Echo "Old RDP value=" & dwValue

  Set new value
dwValue= 3389
oReg.SetDWORDValue HKEY_LOCAL_MACHINE,strKeyPath,strValueName,dwValue
If Err = 0 Then
   oReg.GetDWORDValue _
       HKEY_LOCAL_MACHINE,strKeyPath,strValueName,dwValue
   WScript.Echo "New RDP Value =" & dwValue
Else 
   WScript.Echo "Error in creating key" & _
       " and DWORD value = " & Err.Number
End If
