Hi all, I have written some code which monitors three digital multimeters and appends the data to a csv file. Users of my code were telling me that they were getting this error (attached), and then they would click continue and it would start recording again data again. This happened twice. I tried recreating the problem by opening the file and it happened (obviously). It would not let me continue until I closed the file, of course. However, the other users said that they did not have to close any file and that no file was ever opened. I am not sure how long the error message was open for when they were running the code. Are there any ideas why this might happen other than the file being open? I attached the error message. In my code, I write a header file using the Write to Spreadsheet.VI and as it is recording data, I am just appending to the spreasheet using the save VI. I took a picture of where it is being appeneded to rather than attaching my project (it is really big), but if you need to see more, let me know. Thank you!

Natalie, You might also try using the basic text file tools rather than the spreadsheet file VI. For each call to this particular VI, it opens the file reference, appends the data, and closes the file. If you are writing many samples very quickly, the better solution would be to open the file once, write to it as needed and then close the file when finished. This would guarantee that your code has sole access to the file.

Solved!

See attached VI updated to use a text file.

Thank you so much!

I got it working with shift registers for the time being.

I have learned a lot from your advice and will make those improvements soon. 🙂
