I have a problem reading variant data from an unflattened string. It worked fine in LV5.1, but returns NULL data in LV6.0.2.

I am sending data via a C++ activeX component. In LV5.1, the string was parsed correctly. In LV6.0.2, I get null values for the second part of the string. I am wondering if there is a data type change. The code is enclosed.

Did you mean to post this question in the LabVIEW newsgroup? Your chances of getting a response will be grealty increased in the LV group

There have not been any data type changes that I'm aware of. Are you sure everything is the same as you had it in 5.1. Do you mean that you're getting NULLS from the variant conversion? Are you sure your variant types match correctly? Sometimes it helps to view the flattened string in HEX code to see if you are recieving what you think you are.
