Let me lay out the scene: My application logs data in a .csv file. The file is created with R/W permissions through the "Open/Replace/Create File" VI. Then it uses the "Write to Binary File" to log the data, keeps the reference opened all along, and only close the file at the end. https://lavag.org/topic/18316-opening-file-in-read-only-in-excel-causes-lv-write-permission-error/ So far everything works perfectly. If I double click on the file in Windows Explorer, Excel sees that the file is being opened in LabVIEW and shows the typical message giving me the following choice: Read-only, Notify, or Cancel. If I cancel, Excel closes and things keep on going fine. However, if I do click "Read only", the "Write to Binary File" function in my LabVIEW application throws an error 8: File permission error. Somehow opening the file as read-only in Excel steals the write permission of LabVIEW. Have you ever experienced this? What could be happening?

In a similar situation, I wrote code that closed the file after every write and immediately set the Read-Only flag on the file, so that Excel would always open it Read-Only. When I needed to append to the file, it cleared the Read-Only flag and immediately opened it with write access. Kind of inelegant, but it worked. The user could open the file in Excel at (almost) any time and see the most recent result

Try: chmod 600 jmxremote.password Plus I suggest you'll make your own password file and run it with -Dcom.sun.management.jmxremote.password.file=pwFilePath All explained here. share|improve this answer edited Mar 28 at 20:23 PastPawn 465 answered Oct 7 '13 at 8:55 Elad Tabak 584415 Thanks, that did it! –Black Magic Oct 7 '13 at 12:33 2 Windows users, check this answer to another question: stackoverflow.com/a/6501127/1143126 –RobertG Mar 21 '14 at 9:54 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password
