i make mods for a pc game using the publisher's downloadable tools that are available to everyone. the modding process is very tedious and long, since i have to look through long text files and change values, and hope that i don't make a mistake somewhere.

i have also recently starting learning c++. i know just the basics. i want to make a program that can help me out and help other modders out there. i know i will need a GUI, be able to read from a text file line-by-line and recognize a bank of keywords and display selected settings, and i will also need to go to specific lines in a text file by finding keywords and changing the corresponding values to the user input.

i'll do the learning i'm just asking for a nudge in where to start or if anyone has any basic source code examples that deals with reading, writing, deleting specific values in a text file.
