Difference in UNDO behavior while closing the file

[Mathan]

Kindly follow these steps. Please explain whether it is the expected behavior.

1) Select a new VI and drop any function in the BD and UNDO the operation. Close the file, LabVIEW prompts "Save changes before closing?"

2) Select a new VI and drop a vi using "Select VI" and UNDO the operation. Close the file, LabVIEW will close without any changes notification.

If you make 1 change and then undo that single change, wouldn't you expect that 0 changes have been made (1-1=0)? I see nothing abnormal about this behavior.

Thanks for the response Dennis sir, the above point is OK for case 2. But in case 1 when in a new VI , i placed a for loop and UNDO that and when i closed the file, it asks for saving changes. ????

Okay, sorry I missed the first part.

I actually sometimes see the behavior when using the select function as well. Don't see any reason for this but I would be hard pressed to call it an actual bug. What version of LabVIEW are you using?

[Mathan]

Thanks for the response. Am using LabVIEW 2009 f2.

Any explanation for this bahavior from blue people? Is it a bug or not? I will close this thread based on any feedback from blue people.
