Use the Compare VI Hierarchies tool to compare two hierarchies of VIs. LabVIEW compares any file with the same name in both hierarchies and categorizes them as being the same or different. VIs with the same name and path are considered shared VIs. All other VIs are categorized as added or deleted from the first VI hierarchy. After the comparison completes, the Compare VI Hierarchies dialog box displays a summary of the differences. The VIs in Hierarchies listbox displays the VIs and a symbol that indicates how they are categorized. You can select a set of VIs that have differences and visually compare them using the Compare VIs tool.
Because LabVIEW cannot compare two files with the same name, the Compare VI Hierarchies tool renames one of the VIs for comparison. The first VI is left as is, and the second VI is moved to the temporary directory with a cmp. prefix. Because the Compare VI Hierarchies tool does not rename the subVIs, the renamed VI links to the subVIs loaded by the first VI.
Complete the following steps to use the Compare VI Hierarchies tool.
You can click the Read Hierarchies button to categorize the VIs in the hierarchy. VIs that need to be compared are categorized as not compared. You can selectively compare individual VIs by double-clicking an item or clicking the Show Differences button.
Press the <Ctrl-period> keys to abort comparisons of large VI hierarchies.
