GeneralIDispatch Property Setting Pin

When setting the property of a COM object via IDispatch::Invoke() using DISPATCH_PROPERTYPUT, it is important to set the following :

* DISPPARAMS.rgdispidNamedArgs must point to a DISPID whose value is
DISPID_PROPERTYPUT (-3).

* DISPPARAMS.cNamedArgs must be equal to 1.

If this is not done, IDispatch::Invoke() will return DISP_E_PARAMNOTFOUND. The following is a sample IDispatch::Invoke() call used to set a long property to value 202:

void InvokeProperty(IDispatch* dispatch)
{
DISPPARAMS dp;
long nError = 0;
long nWarning = 0;
DISPID dPutID;

memset(&dp, 0, sizeof(DISPPARAMS));
dp.cArgs = 1; // Number of arguments to Invoke() remains 1.

// This is important.
dPutID = DISPID_PROPERTYPUT;
dp.rgdispidNamedArgs = &dPutID;
dp.cNamedArgs = 1;

VARIANTARG* pArg = new VARIANTARG[dp.cArgs];
dp.rgvarg = pArg;
memset(pArg, 0, (sizeof(VARIANT))*(dp.cArgs));

V_VT(&(dp.rgvarg[0])) = VT_I4;
V_I4(&(dp.rgvarg[0])) = 202;

VARIANTARG vr;
VariantInit(&vr);

//Finally making the call
UINT nErrArg;
HRESULT hr = S_OK;

hr = dispatch -> Invoke(0x03, IID_NULL, LOCALE_SYSTEM_DEFAULT, DISPATCH_PROPERTYPUT, &dp, &vr, 0, &nErrArg);

return;
}


By the way, I also checked up MFC's implementation codes for
COleDispatchDriver. It does the same thing, i.e. set
DISPPARAMS.rgdispidNamedArgs to DISPID_PROPERTYPUT and DISPPARAMS.cNamedArgs
to 1 before calling Invoke().
