This example demonstrates how to retrieve the data type of all front panel objects through the use of VI Server, Property Nodes & Scripting Property Nodes.
LabVIEW has no direct way for determining the data types of the objects on the Front Panel, this example scans through the Front Panel Objects and returns their datatype to an output array. The output array is ordered based on the control index of the Front Panel Object.
It does this by analyzing the general class name for the object, and then determining whether further evaluation is required. For e.g. an object with the class name of Boolean could be put straight into the array; However an object with the class name of Array would require further investigation to determine the representation of the elements in the array.
For determining the exact type of numeric/refnum/cluster etc., a variety of Scripting property nodes, standard property nodes and lookup tables are used where required.
While most data types are relatively straight forward to determine through this method of searching for representations or checking lookup tables, it is worth noting that clusters require a recursive method due to the ability to place clusters within clusters.
All of the code is documented; However if anything is unclear (or errors are spotted), feel free to comment and I'll be happy to discuss it further.
