Problem in using EnableStatic....

[santosh]

Hi All ,
I am facing a problem while using EnableStatic Method. The error
messages in Win2k and Win3k are as follows

1)In Win3k

ExecMethod hr = 0
EnableStatic method output :
instance of __PARAMETERS
{
ReturnValue = 2147786788;
};


2)In Win2k
ExecMethod hr = 0
EnableStatic method output :
instance of __PARAMETERS
{
ReturnValue = 94;
};


I am using the code as below
SetIPAddress(CComBSTR InstancePath , vecString IPAddress , vecString
SubnetMask)
{
IWbemClassObject *pMethod = NULL;
IWbemClassObject *pOutInst = NULL;
IWbemClassObject *pInInst = NULL;

CComBSTR methodName = _T("EnableStatic");
CComBSTR ArgIPAddress = _T("IPAddress");
CComBSTR ArgSubnetMask = _T("SubnetMask");
HRESULT hr;

do {
// Get the method we want to use in this class
hr = m_pClass->GetMethod(methodName, 0, &pMethod, NULL);
if (FAILED(hr))
{
Trace(_T("Failed pClass->GetMethod"));
break;
}

// Spawn an instance of the method so we can set it up
(parameters)
hr = pMethod->SpawnInstance(0, &pInInst);
if (FAILED(hr))
{
Trace(_T("Failed pMethod->SpawnInstance"));
break;
}

// Insert the ip address and subnetmask into an array
// EnableStatic() expects to receive the args in an array

hr = _PutArgInMethod(pInInst, ArgIPAddress, &IPAddress);
if(FAILED(hr))
{
Trace(_T("Failed to insert parameter %s into method"),
ArgIPAddress.m_str );
break;
}

hr = _PutArgInMethod(pInInst, ArgSubnetMask, &SubnetMask);
if(FAILED(hr))
{
Trace(_T("Failed to insert parameter %s into method"),
ArgIPAddress.m_str );
break;
}

// finally we get to call the actuall method we want
(EnableStatic())
hr = m_pNameSpace->ExecMethod(InstancePath, methodName, 0,
NULL, pInInst, &pOutInst, NULL);

#if _DEBUG
BSTR bstrText;
pOutInst->GetObjectText(0, &bstrText);
Trace(bstrText);
#endif

} while (FALSE);

RELEASE_AND_NULLIFY_REF(pMethod);
RELEASE_AND_NULLIFY_REF(pInInst);
RELEASE_AND_NULLIFY_REF(pOutInst);

return hr;
}

Is there any problem with the above code?? or is there any dependency
for using it??
If anyone has success in using EnableStatic , can u post the working
code snippet??
All the help will be very much appreciated..
Thanks

In W2K3 the EnableStatic uses the same interfaces used by the
NetworkConnection UI
for uniformity of behaviors and errors. Your error below is

#define NETCFG_E_NO_WRITE_LOCK
MAKE_HRESULT(SEVERITY_ERROR, FACILITY_ITF, 0xA024)

that is normally caused by one other application holding the write lock in
the TCP notify object.
Do you have the NetworkProperties page opened ?
