<p>I have a base class object array into which I have typecasted many different child class objects and am passing it to a sub vi. Is there any way by which I can find out the original type of the object of each individual elements in the array?</p>

<p>Thanks ...</p>

NI has a good
overview of LVOOP
that is a must-read, since OO is implemented in a unique way for LabVIEW.
Have you tried the '
to more generic class
' and '
to more specific class
' functions, on the application control palette?
