Hi,
If you are using a OLE interface I think you will be using the Active X Automation adaptor.
TestStand Active X Automation Adaptor automatically converts BSTR when it store the data in a TestStand variable.
Then you should be able to use the regular string functions which are available in TestStand to parse the strings.
Please let me know if you have any more questions.
