Hello all

Sorry but I haven't got any code yet because I first have to know it is possible (didn't find much interesting on google). My problem: reading bits from a file and manipulate them. So I have to get the 0's and the 1's from a file in an array or something, adjust them and make a file again with them. Is this possible? You guys could help me with some example code or some useful function names. I would really appreciate that smile.gif

thx
Jasper

System.IO.StreamReader and System.IO.StreamWriter or two good places to start once you read the file in you can manipulate the data and then write it back to the file

reading the file isn't the problem, but I want the bits from the file, for example from a zip archive.

So you want to take a file out of a zip or rar file edit it and then place the newly edited file back in the zip or rar

maybe the zip archive example wasn't good. but.. every file is build of bytes, you can see that when you check the filesize. Well.. I want to manipulate those bytes no mather from what file. I hope that's possible

for example if the first byte is: 10010010 i want to change this to 01101101
