Hi,I`m new here and I want to sorry first for my english^^I have a similar problem as Daryl before. I have an array of cluster. The cluster is a Typedef with one string, two numerics, a boolean and a combo box.The entries for the array I get from an .ini file. Every line of the array is filled with different values, so also the Combo boxes have to be filled with different values.I have tried the example above, but where the "to more specific class" VI with ListBox connected is, I become an error with: Possible reason(s):LabVIEW: Type mismatch: Object cannot be cast to the specified type.I don`t know, what I do wrong. The index of controls[] array is the right one.
