Hi All,
I have an application where I store the data in a cluster. Suppose this is my ver. 1 of the application and the cluster consists of 3 I32. and I ship this application to the customer.
Now for the ver 2 I want to store a string to the cluster so I updated my cluster to 3 I32 and 1 String. But this ver 2 should also be able to read ver 1. just like MS Word 2007 is able to read .doc files
In my design, I am stroing the version number and data(as variant) in a cluster and convert that cluster to variant and do a 'variant to flattened string' before saving it to a file.
I am attaching my desing protoype here so you get a better idea of what I am talking about and suggest me if you think it can be done in a better way.
Thanks,
Ritesh
