复制代码 代码如下:

}

// Variables used

// Get DISPID for name passed

if (FAILED(hr))
{
wprintf(L"IDispatch::GetIDsOfNames(\"%s\") failed w/err 0x%08lx\n",
ptName, hr);
_exit(0);
return hr;
}

// Allocate memory for arguments
VARIANT *pArgs = new VARIANT[cArgs + 1];
// Extract arguments...
for(int i=0; i < cArgs; i++)
{
pArgs[i] = va_arg(marker, VARIANT);
}

// Build DISPPARAMS
dp.cArgs = cArgs;
dp.rgvarg = pArgs;

// Handle special-case for property-puts
if (autoType & DISPATCH_PROPERTYPUT)
{
dp.cNamedArgs = 1;
dp.rgdispidNamedArgs = &dispidNamed;
}

// Make the call
hr = pDisp->Invoke(dispID, IID_NULL, LOCALE_SYSTEM_DEFAULT,
autoType, &dp, pvResult, NULL, NULL);
if (FAILED(hr))
{
wprintf(L"IDispatch::Invoke(\"%s\"=%08lx) failed w/err 0x%08lx\n",

_exit(0);
return hr;
}

// End variable-argument section
