How to read fixed position/length string -
I have a bunch of files that i need to read line by line, and for each line I need to read the characters (in a group) by position into a table, such as position 1 -5 is a group, 6-10 is a group, etc. These are ach nacha files if you know what those are. I'm not familiar enough with vb.net to know what my options are. I was thinking I could use a streamreader to read each line. and I found readblock, but I haven't found anything as far as an example that I could understand how it works, or how I could make it work for what I need. Any suggestions would be greatly appreciated.
