imaqSetWindowThreadPolicy

Usage

int imaqSetWindowThreadPolicy(WindowThreadPolicy policy);

Purpose

Determines the thread in which NI Vision creates windows. By default, NI Vision uses IMAQ_CALLING_THREAD. This policy creates windows in the thread that makes the first display function call for a given window number. If that thread does not process messages, set the window thread policy to IMAQ_SEPARATE_THREAD. Using this policy, NI Vision creates windows in a separate thread and processes messages for the windows automatically.
