I am using LabVIEW 2009 SP1 on Win XP OS system. I am reading and writing data to a text file whose size does not exceed 50 MB. whenever i try to set file position to a value of say 128 bytes from the start of file, the function does not show an error. But when i try to read back the file position using get file position function, the value shows a very high number. I am not able to do a random access read of the file data. Please help.
