Hello to all. I would like to know how I can close my program ordely. I mean... I have 4 whiles in my program so when user clicks a "stop" botton close ordely: while 1 and when it is finished then close while 2 then close while 3.... How can I do that just with a stop botton? Thanks a lot.

Hi all, I have an error that doesn't affect the functionality of my program, so for the moment I'm just ignoring it, but anyway I would like to know what is its cause and how can I solve it, or if it's safe to ignore it. I have a program that makes some tests and stores the data in some clusters, and then when the job is done it writes everything in a database. Then it asks if you want to start another job or end the program. Up to there everything works perfect. But if you choose to start another job without closing the program, after you complete it there's an error at the end of the database writing. The error is this: Error 505 occurred at NI_Database_API.lvlib:DB Tools Close Connection.vi->Escritura DB.vi->Interfaz Principal.vi Possible Reason: Open Command Object. ADO Error: 0x000001F9 As you can see in the attached image, in my database writing subVI I only open connection, use two "Insert Data" blocks and then close connection. I don't have any command references to use the Free Object block, so I don't know what's wrong. Thanks in advance for any help.
