Hi

I am currently working on file handling to insert or remove data from the same file, depending upon the choice. So i need to do like this

IP Address (one tab space) MACAddress (one tab space) Starttime (one tab space)Endtime
192.xxx xxxxx xxxx xxxx

in that fashion i shld go on adding ip , mac address etc.

the adding or deleting is upon our choice. while deleting i shld delete the last entry made to the row. and while adding ,its normal and if suppose its after a deletion of that row. i shld add it in the same row i deleted.

Can anyone help me with this?
