How do i read a text/notepad file using VISUAL BASIC? If possible ,can i add data to the existing text file?

Answer 1

to read the file:

OPEN "some\path\to\file.txt" for Input as #1
Input #1, Varnames
Close #1

To write to the file

Open "some\path\to\file.txt" for APPEND As #2
Print #2, varnames
Close #2

This is using VB-6, since you didn't specify a version of the language.

Every programming/scripting language has the basic File I/O Stuff attached. Its there in C,C++,COBOL ,FORTRAN,VB,VB Script, Java JavaScript et all.The question is where do you find them and how badly you need them.

Based on that your problem is solved. :)
