post an example of the textfile, and we can go from there. The concept is fairly simple, however. You open the text file, and while you are reading in all the contents, compare each line with whatever you are looking for (say, the persons social security number), and then if they do not match, add that line to a string (or to another, temp file), and if they DO match, simply don't add it to the new file (or the string variable).

2005/11/11 17:50:58, Event:Access, Door:entry, Card No.:2345, Description:266:55732

thanks

Read each line
If it contains "Event:Access, Door:entry, Card No.", write it to the file
If not, don't
If not at end-of-file, go back to read the next line

thanks to your reply,but sir a want a sample code..thanks

Please sir, first answer these questions:
1) do you know how to open a file?
2) Do you know how to read the file one line at a time?
3) Do you know how to check if a line (string) contains specific substring?

And finally
4) Are you trying to learn how to program, or have the program written for you?
