read binary file

[Alann]

Can LabVIEW only read the binary file written by LabVIEW??

 Actually I am trying to read a binary file written by a C++ program and it gives error of truncated data. May be that's because there is no data size information at the beginning. (which I think is appended by Write Binary File VI in LabVIEW).

You can read any kind of binary file with LabVIEW, but you need to know the structure of the file (data type, byte order (little endian vs. big endian) etc.).

Can you tell us a bit more what the file contains? Can you attach a small file sample?

I saw this issue a little while ago, when someone was trying to transfer binary data between LabVIEW and Matlab.
The issue (as Altenbach suggested) ended up being the endianness. Check if c++ writes/reads using little endian or big endian.

LabVIEW has a function to convert back and forth between little and big
