I would like to ask about I/O in vb.NET
Suppose i have a txt file contains "12345678"
how can i get "2" then replace "a" Without Load all data into a string or
This depends on if you know where in the file the number is located.

'BinaryWriter', 'StreamReader', 'StreamWriter'), and their 'Read' and
'Write' methods.
