Hello,

take a look to this discussion that offers some concept and solutions.

Thank you very much! I have solved my problem through PostDeferredCallToThread.

First, I get the mainthreadID with function FmtGetMainThreadID, and then call the function PostDeferredCallToThread, and I can return where I define my CVICALLBACK function.
