I was puzzled by it for long.
I want to get CAN messages from an application, which has already support COM activeX api and can return one message after each call(it directly return variables ,not a cluster).
but this method,one by one, is much too slow ,I want to get the messages by mass.
but , it seems that , ActiveX can not support Cluster array return value, a proper way may be variant.
I check the EXCEL activeX call , and find it is indeed using variant, to return string array, which is a little similar of Cluster array. see as below:

So , I want to get an example ,showing what should I do in C codes and Labview code , so as to get Cluster array by variant.
great thanks .
