I have .VI file that was working fine under Labview 6.1. However, after Labview 7.0 is installed, some of the subvis are not working. When I clicked into my .VI, it says it is searching for AI Read One Scan.vi. I also have AO in the .VI. So far, I could not find the new name or function of these two? Is there any way, I can have smooth transition from version 6.1 to 7.0? I do not want to find each question mark in the older version .vi to convert the new version of module. Any help, appreciated.
