I am new to this forum like i am new in VB. I've some questions. I searched forum for answers but i can't find reasonable answers. So here are my questions.

1.) How can i hide the strings and numbers using in VB from being debugged without using encryptions like the serial numbers are hidden in softwares.

2) How can i convert the strings to ASCII or HEX codes and vice versa.

3) How can i check the existence of another file say a text file, and to read that file. Or to create a new file if is not there.

Can anyone help me by providing with code or some tutorial link or some links to another post of the same nature.

Hi and welcome to the forum :-)
A few answers:
1) Use the ASCII numbers for your strings rather than holding them in the code.
Example:

dim pwd as string dim i as integer i=64 pwd = pwd & chr$(i) i=65 pwd = pwd & chr$(i) i=66 pwd = pwd & chr$(i) ' comment - remove this line - pwd = @AB

However, this is a lot of code and may be more trouble than downloading some decent encryption.
2) To convert decimal to hex, use the HEX function - see help for usage. I also found this http://www.freevbcode.com/ShowCode.asp?ID=6741 from www.google.com for conversion
3) To check if a file exists:

if dir$("c:\foo\bar\myfilepath.txt")<>"" then 'file exists end if

Hope this helps,
Kieron
