small question

Actually there were two jumps first comes on the first digit of ANSI text string of IP address (was fixed for 14 bytes) and second jump landed just after this string.there fore I was unable to change the length of string.Anyway I found out solution and the programme is working very good.

Delphi string can be a short string, long string or a PChar type (null terminated). In your case, I guess it is a short string or a long string. If they are, the dword preceding will contain the length of string. So you need change it from 14 to 15 (0E to 0F). The Delphi long string need a null char (00) at the end of string content.
