    // PROPERTYGET _and_ METHOD to be set. With only one of these set the call
    // fails.

    // need to be compatible with VisualBasic which does not distingish methods
    // and property getters and will set both flags always.
    //
    // The MSDN article advises this behaviour: "[...] Some languages cannot 
    // distinguish between retrieving a property and calling a method. In this 
    //case, you should set the flags DISPATCH_PROPERTYGET and DISPATCH_METHOD.
