Select Tools»Compare»Compare VI Hierarchies to display this window.

Use this window to compare two VI hierarchies.

This window includes the following components:

• First VI Hierarchy—Indicates the top-level VI of the first hierarchy that you want to compare.
• Browse Files—Browses to the top-level VI of the first hierarchy that you want to compare.
• Browse Memory—Launches the Select a VI dialog box so you can select a VI in memory.
• Second VI Hierarchy—Indicates the top-level VI of the second hierarchy that you want to compare.
• Browse Files—Browses to the top-level VI of the second hierarchy that you want to compare.
• Browse Memory—Launches the Select a VI dialog box so you can select a VI in memory.
• Read Hierarchies—Reads and analyzes the two VI hierarchies. LabVIEW determines whether the VIs are new, deleted, shared, and so on.
• Compare Hierarchies—Compares the two VI hierarchies. If you did not click the Read Hierarchies button, LabVIEW reads and analyzes the hierarchies before comparing them.
• Save to File—Saves the differences between the two VI hierarchies to a text file.
• Compare—Indicates the attributes you want to compare.
  • VI attributes—Compares attributes of the two VIs using the settings in the VI Properties dialog box.
  • Front panel—Compares objects on the front panel.
    • Position/size changes—Compares the position and size of the objects on the front panel.
  • Block diagram—Compares the functional differences on the block diagrams.
    • Cosmetic changes—Compares changes on the block diagrams that do not affect the execution of the VI, such as color changes, visible subdiagrams in Case and Stacked Sequence structures, format and precision of constants, and Event structures.
    • Position/size changes—Compares the position and size of the objects on the block diagram.
• VIs in Hierarchies—Lists all the VIs in the two hierarchies.
• Description—Describes the differences in the VI selected in the VIs in Hierarchies field.
• Show Differences—Compares the VIs that you select in the VIs in Hierarchies field and displays the differences in the Differences window.
• Legend—Describes the symbols used in the VIs in Hierarchies field and the Description field.
  • different—Indicates that the VI has one or more differences.
  • same—Indicates that the VI does not have any differences.
  • added to first hierarchy—Indicates that the VI exists in the first hierarchy but not in the second.
  • deleted from first hierarchy—Indicates that the VI exists in the second hierarchy but not in the first.
  • not compared—Indicates that LabVIEW has not compared the VI.
  • shared VI—Indicates that both hierarchies share the VI.
• Done—Closes the dialog box.
