I'm using variants to save configuration data for an application that I'm building. Specifically, the configuration data is packaged in a cluster of a cluster and an array of clusters. Within the first cluster is an image path, two doubles and two ints, and each element within the array of clusters is a string and two doubles.
I convert this cluster to a variant and then the variant into its pieces (Variant To Flattened String.vi), convert the array of I16's to strings, concatenate the array of strings with the data string into another array, and then save that array to a spreadsheet file in a text file. I close the text file as soon as this is done.
The exact opposite procedure is done to get the cluster out of the text file.
This VI executes within the scope of a much larger program with other things concurrently happening. The process works most of the time. I can both save to and load from the text file. However, sometimes, and I am really at a loss as to when, this process fails because there is a failure translating the variant. The text file is then corrupt and can no longer be read. Has this problem ever been seen before, or does anyone have any idea where I can start in debugging this?
Thanks.
