IDispatch and word CheckSpelling problem   

Hi,
I'm trying to use CheckSpelling method and have some problems.
I use code below:
CLSID clsid;
    CLSIDFromProgID(L"Word.Application", &clsid);

    IUnknown* pUnk;
    HRESULT hr = ::CoCreateInstance( clsid, NULL, CLSCTX_SERVER,
                                     IID_IUnknown, (void**) &pUnk);
    IDispatch* pDispApp;
    hr = pUnk->QueryInterface(IID_IDispatch, (void**)&pDispApp);

    // Get IDispatch* for the Documents collection object
    szFunction = OLESTR("Documents");
    hr = pDispApp->GetIDsOfNames (IID_NULL, &szFunction, 1,
                                  LOCALE_USER_DEFAULT, &dispid_Docs);
    hr = pDispApp->Invoke (dispid_Docs, IID_NULL,
                           LOCALE_USER_DEFAULT, DISPATCH_PROPERTYGET,
                           &dpNoArgs, &vResult, NULL, NULL);
    pDispDocs = vResult.pdispVal;That way I can open word, write text to it,
save it, but have no idea how to call CheckSpelling, when I do this
GetIDsOFNames return some ID but when I callinvoke I'm geting error:
IDispatch* pDispSpell;
    szFunction = OLESTR("CheckSpelling");    hr =
pDispDocs->GetIDsOfNames(IID_NULL, &szFunction, 1,
                                  LOCALE_USER_DEFAULT,
                                  &dispSpell);    hr = pDispApp->Invoke
(dispSpell, IID_NULL,
                           LOCALE_USER_DEFAULT, DISPATCH_PROPERTYGET,
                           &dpNoArgs, &vResult, NULL, NULL);All examples on
the net are with VB, very little with C++, any tip how to use that spell
check object?thanks

CheckSpelling is not a property, it's a method. Try with DISPATCH_INVOKE 
in place of DISPATCH_PROPERTYGET.
