(sorry for my english) I use nidaq with hard real-time acquisistion in win2000, in double-buffered mode. Sometimes, my application, don't read the halfbuffer and 10846 code (is plus, is a warning) occur. After, every check of DAQ_DB_HalfReady return 10846 code, and i can't see if another failure in read occur. How can i reset the status code? Thanks, Piero.
