XML-RPC

[WaZZu]

Hello,

I'm trying to create a C++ class from nsIXmlRpcClient under win32,
using MSVC and getting following compilation error:
[...]\xml-rpc\nsIXmlRpcClient.h(158): error C2528: 'uuid' : pointer to
reference is illegal
and
line 158: NS_IMETHOD CreateType(PRUint32 type, nsIID & *uuid, void *
*result) = 0;

I was wondering if anybody has experienced this problem before, or is
it just my compiler can't handle this code.
Any help is appreciated.
Thanks.

OK, I've tried to call Mozilla XML-RPC scriptable from C++ source.
When I do AsynCall, my return result is
NS_E_SET_DISK_UID_FAILED(0x80570021).

Could somebody point me out, if I'm doing anything wrong?
Thanks.

Here is the source code I used:

////////////////////////////////////////////////////////////////////////////
// XML-RPC Client Listener implementation
////////////////////////////////////////////////////////////////////////////
class CXMLRPCListener : public nsIXmlRpcClientListener
{
public:
NS_DECL_ISUPPORTS
NS_DECL_NSIXMLRPCCLIENTLISTENER
CXMLRPCListener(){}
};

NS_IMPL_ISUPPORTS1(CXMLRPCListener, nsIXmlRpcClientListener)

NS_IMETHODIMP CXMLRPCListener::OnResult(nsIXmlRpcClient *client,
nsISupports *ctxt, nsISupports *result)
{
nsresult rv;
nsCOMPtr<nsISupportsPrimitive> resSup(do_QueryInterface(result));
nsCOMPtr<nsISupportsCString> p(do_QueryInterface(resSup));
nsCAutoString data;
p->GetData(data);


return NS_OK;
}

NS_IMETHODIMP CXMLRPCListener::OnError(nsIXmlRpcClient *client,
nsISupports *ctxt, nsresult status, const PRUnichar *errorMsg)
{
return NS_OK;
}

NS_IMETHODIMP CXMLRPCListener::OnFault(nsIXmlRpcClient *client,
nsISupports *ctxt, nsIXmlRpcFault *fault)
{
return NS_OK;
}

//////////////////////////////////////////////////////////////////////

nsresult rvRpc;
nsCOMPtr<nsIXmlRpcClient> xmlRpc = do_CreateInstance("@mozilla.org/xml-

xmlRpc->Init("http://betty.userland.com/RPC2");
nsCOMPtr<nsISupportsPRInt32> element = do_CreateInstance("@mozilla.org/

element->SetData(47);
nsCOMPtr<nsISupportsArray> ary;
NS_NewISupportsArray(getter_AddRefs(ary));
ary->AppendElement(element);

CXMLRPCListener *listener = new CXMLRPCListener;
rvRpc = xmlRpc->AsyncCall(listener, nsnull, "examples.getStateName",
getter_AddRefs(ary), 1);
