read numbers from a constantly updated file

[william879]

Dear All,

I am a newbie in labVIEW. Currently I am facing a probrom with reading a number from a .LVM file.

One VI is constantly write the values in a file. I want to read the last number on that file and displace it on another VI simultanously.

The "read Measurement file" seems can only read all numbers at the same time.

Please help!!!!!!!!!!!!!!!!Thank you!!!!!!!!!!

Hi william879,

are both vi´s from you? If yes i think a better solution is to send the last of the saved values to the other vi by using queues or notifier. If you need to read from the file you can use the LabView functions "Open File, Set File Position, Read From Binary File, Close File" to read only a part of it.

Hope it helps.

Mike
