Comparing VIs

[jvh75021]

Sometimes I would like to compare the current VI to a previous version. The compare tools only compares VIs in memory and two VIs in memory cannot have the same name. So I save the current version as desktop:\temp.vi and then open the previous version from CD. 

After running Tools > Compare > Compare VIs and then closing the VIs many dependencies are fouled up and then LabView and TestStand are trying to load VIs from CD or complain about dependencies.

Is there a convention for renaming files and running VI comparisons that doesn't cause problems.

thanx,

jvh

Towards the bottom it talks about it.

Comparing Two VIs with the Same Name

You can compare two VIs with the same name, but these VIs must reside in different LabVIEW projects, and you must open these VIs from the project.

After you open the VIs, select Tools»Compare»Compare VIs to compare the two VIs. Refer to the beginning of this document for more information

Thanks, Bryan.

This is a good little article.

 Unfortunately the 2nd reference at the bottom of your post would not open for me.

If you go to the linked page and read the section "Comparing Two VIs with the Same Name" that is the part I pasted into my post.  So the 2nd link just takes you to the top of the linked page.  I guess when I copied the info it was kept as a link.
