How do I compare two VIs in LabVIEW?
In LabVIEW, you easily can compare two VIs with different names using the Compare VIs dialog box to compare two VIs that are open in LabVIEW (in memory). If no VIs are in memory, LabVIEW grays out the Compare VIs menu item.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.
Note: To compare VIs using a third-party source control provider or the command line, use LVCompare.exe (LabVIEW 2011 Help: Configuring Source Control with LVCompare.exe).
Complete the following steps to compare two VIs that are open in LabVIEW.
Select Tools»Compare»Compare VIs to display the Compare VIs dialog box.
In the dialog box, select the VIs you want to compare. Choose which items from the VI you would like to compare by placing a checkmark next to those items. After you select the VIs to compare and the attributes to compare, click the Compare button. LabVIEW shows the two VIs side-by-side, along with the Differences dialog box.
Click a difference in the left pane to see its details. The details describe what type of difference each item refers to. Place a checkmark in the Circle Differences checkbox to place a red circle around the item in each VI that a particular difference refers to. If you highlight a difference and click the Show Difference button, LabVIEW highlights and places a red circle around the item in each VI that contains that difference, as shown in the following block diagram.
Some differences can contain multiple details. When you click the Show Detail button, LabVIEW highlights the particular detail you have selected for a particular difference.
You can use this tool while you edit VIs, but you must click the Update button to populate the Differences pane with the current differences between the two VIs. For more information about the Compare VIs (LabVIEW 2011 Help: Comparing VIs and VI Hierarchies) and the Show Differences (LabVIEW 2011 Help: Differences Window) functionality, refer to the LabVIEW Help.
