You also can access the Differences dialog box by clicking the Show Differences button in the Compare VI Hierarchies dialog box.

The Differences dialog box lists out the differences and details of each selected difference. When you open the dialog box, the first difference in the list is selected and highlighted by default.

If a difference or detail involves only front panel or block diagram cosmetic changes, it appears italicized in the list.

Complete the following steps to selectively find differences between two compared VIs.

1. Click an item in the differences list or the details list to highlight it. A checkmark indicates that you have viewed an item.
2. Use the Include: checkboxes to filter VI attribute, front panel, front panel position/size, block diagram, and block diagram cosmetic differences.
3. Click More commands and select Tile Left and Right or Tile Up and Down to tile the windows of the two VIs.
4. To swap the positions of the two VIs, select Swap VI Positions in the More commands menu.
5. If you make edits after comparing your VIs, some of the differences might no longer exist. Click Update to compare the two VIs again and update the differences list.

Click More commands and select Highlight Differences to display a red rectangle around the object or objects that have changed. When you highlight a difference, objects that are part of the difference are selected. The following illustration shows an example of a block diagram difference.
