Re: Setting registry data

What you are doing is wrong.
You are creating a class object by giving class name. This will try to
create a new object instance for win32_registry and as you pass UPDATE_FLAG
only and so it will always fail and will never work.

What you should do is do either
1. Execquery on win32_registry or
2. Pass the exact path of win32_registry object ( you can enumurate
instances in wbemtest of this class and see the path of that object )

and then follow with the modification,put and putinstance.

Hi Manbinder,

I have used spawninstanc, put instance, Still i am not able to see the
modification happening...
I have attached the code for reference. Please let me know where i am
going
wrong.

void setProposedSize(long theProposedSize){

VARIANT vtProp;
VariantInit(&vtProp);

//This function will connect to server
if( Registry::isInitialised == 0 )
Registry::initialize();

//This getServiceObj will return IWbemServices object
IWbemServices* pSvc = getSeviceObj();
BSTR ClassName = SysAllocString(L"Win32_Registry");

IWbemClassObject* pClass = NULL;
HRESULT hres = pSvc->GetObject(ClassName, 0, NULL, &pClass, NULL);

IWbemClassObject* pClassInstance = NULL;
hres = pClass->SpawnInstance(0, &pClassInstance);


V_VT(&vtProp) = TYPE_UINT;
vtProp.uintVal = (unsigned int)theProposedSize;

cout<<"Setting proposed size :" << theProposedSize<<endl ;

HRESULT hr = pClassInstance->Put(L"ProposedSize", 0, &vtProp, 0);


switch(hr)
{
case WBEM_S_NO_ERROR:
cout<<"suceeded";
break;
case WBEM_E_FAILED:
cout<<"WBEM_E_FAILED";

break;
case WBEM_E_TYPE_MISMATCH:
cout<<"WBEM_E_TYPE_MISMATCH";
break;
}


IWbemCallResult* pResult = 0;
IWbemContext* pCtx = 0;
IWbemObjectSink *pSink = 0;
hr =
pSvc->PutInstance(pClassInstance,WBEM_FLAG_UPDATE_ONLY,NULL,&pResult);

cout<< "pResult:" << pResult << endl;
if (FAILED(hr))
{
cout<<endl<<"failed sadly"<<endl;

}
switch(hr)
{
case WBEM_E_ACCESS_DENIED:
cout<<"WBEM_E_ACCESS_DENIED";
break;

case WBEM_E_NOT_FOUND:
cout<<"WBEM_E_NOT_FOUND";
break;
}

SysFreeString(ClassName);
pClass->Release();
VariantClear(&vtProp);

}

You should first make a new object using IWbemClassObject SpawnInstance

and then you put various property values in that instance using Put
method.
These is uncommited instance. In order to finaly put it you should use
PutInstance method of IWemservice.

Hi,
I tried using the VBScript and it is working fine. I tried the example
C++
code.
The value is not getting set with C++ code. I have a query here -
Which is the equivalent C++ call to Put_ method in VBScript ? Is it the
Put() method of IWbemClassObject or PutInstance() method of
IWbemServices
?
Regards,
Sandhya

Sandhya,

I knew there was another example and luckily I found it, here:

http://groups.google.de/group/microsoft.public.win32.programmer.wmi/browse_t
hread/thread/5f6976ad37f0b51c/6c6b3ba6b003e730?lnk=st&q=&rnum=1&hl=de#6c6b3b
a6b003e730

Again, this example shows how to read values from the registry but I
hope
this shows the way to go.

Hi,

I am using C++ code. Can you please let me know how this can be done.

You can do something like this: (modify the ProposedSize to what
you
require)

strComputer = "."
Set objLocator = CreateObject("WbemScripting.SWbemLocator")
Set objService = objLocator.ConnectServer(strComputer, "root\cimv2")
objService.Security_.ImpersonationLevel = 3
Set Registry = _
objService.ExecQuery("SELECT * FROM Win32_Registry")

For each Reg in Registry

WScript.Echo "Old Size: " & Reg.ProposedSize

Reg.ProposedSize = 77 '<--Change this...
Reg.Put_

WScript.Echo "New Size: " & Reg.ProposedSize
Next

Hi,
Thanks for the reply. What I want to set is proposed size parameter
of
win32_registry.
Please let me know how I can go about doing this.

Look at the stdregprov class

Hi,

I am using WMI to read the data through WQL. I want to set the

Can I use WMI to do the same ?
