Hi,I'm trying to make a LabView application that creates threads, which set andunset digital lines. For some reason I can't include attachments to my posts,but I'll try to explain what I have done so far.I have a one VI that runs forever in a while loop and sets a digital line to 1 or 0every 500 ms. This VI is defined to be reentrant. From this VI I would like to havenumerous of instances with different digital lines. This VI is supposed to be thebase from the threads. The digital port is the only thing that is different in eachthread.I use another VI to create these threads with Invoke Method. First this VI usesOpen VI Reference. Then I use Invoke Method to get the type descriptor of thecontrol I want to change in the VI. Next I call Invoke Method to set the digital portto be used with parameters gotten from the previous Invoke Method. And finallyI call Invoke Method: Run VI.I get an error that states "Memory or data structure corrupt". The source is in theset value.Hopefully this makes at least some sense and someone can give me some tipson how to do this.Thanks.P.S. I'm trying add files to my posts from the "Browse..." button that is located atthe bottom of this message writing page, but for some reason the attachmentsdoes not show. Am I doing something wrong?

Thank you Felix for your reply.

I might need to use that Open Vi Reference technique you mentioned for implementing
callbacks. I'll play around with it to see what can I do and then come back with the questions.
Propably in a new thread, so keep your eyes open for that
