Playing with text

[greifedc]

Hello,
I am a new user, Not just to .net but to development all
together. I appriciate everyones patience eith my very
beginer questions. I need to manipulate large (10m) text
files. I have written some code to do this useing
streamreader to load file contents into a listbox then
manipulateing the text with the stringBuilder class. This
is veeeery slow. reading and manipating takes way to long.
Am I going about this all wrong?

I dont have time to look at your code, but the listbox is almost certainly the biggest slowdown in your code. Why do you need it?

I need to be able to display the text for user verification and input. Should I not be useing listbox?

TextBox would be more suited, surely?
