How to delete data on .txt file in VB6?

[noielen]

actually after i read the line and before i delete it, i store that line into access db. coz now has many calls, and if i didn't delete the old lines in a file, my program will load slow coz my code is to read all the lines and check if that is new call(s).

and access db now contains all old and new data lines or calls.
so what i want to know now is how to delete a (particular) line in a file? tnx...
