Hi Due, Here's what I tried and it all worked well on my computer:
1) File >> New VI 2) Placed an Automation refnum control on the front panel. 3) Right-click on the refnum >> Select ActiveX class >> Browse >> Microsoft Forms 2.0 Object Library version 2.0 >> ListBox 4) Place an invoke node on the block diagram. Select "Add Item". 5) Wire numeric data to the input of the method. Please follow these steps and let me know how it goes. Sincerely, Feroz National Instruments
