How to make common control?

Hi Dusk,

 

why are you creating several subVIs which contain the very same content? (Atleast it seems so from a quick glance at them.)

They are calling some DLL functions: either the DLL supports multithreading, then you should set your VI reentrant - or they don't support multithreading, then you should call them one after the other…

 

Anyway the problem is in your main VI: Learn to use autoindexing and learn, how to handle arrays!

Both are basic LabVIEW concepts and you should know about them, before handling DLL calls…

Best regards,
GerdW
