Two phase process:
Traverse the FP for controls (I assume you are familiar with the Traverse for References VI). Cast the references to Control class, use the TypedefVI property to find the Type Definition. If it is a valid reference (Not Not-A-Reference), the use the VI Name property to get the TypeDef name, compare to your target. You can build an array of references this way.
Similarly traverse the BD for constants, other than casting to Constant, the rest of the code is the same.
