Dude,
This seems way over your head.......................

you would have to clearly define how those certain command will be stored in your file or if it is predefined you will have to understand them how you can extract the command and understand the certain command.

Even If it is the simplest command I must say you will have to go through parsing.

Do some research on a substring command.
You need to check each line for a specific character / group of characters and then read the next x characters or read until another pattern is matched e.g. if the commands you are looking for could begin with then you search for

How you do this is a question of design. Assuming one useful command per line, then you can left trim everything before the command and right trim to get rid of everything after it. Whats left is your usable command.

If there are multiple commands per line then you will have to tackle SubStr.

First, you need to learn how to use google.

Next, here's a link I found when I googled "MFC open text file":

I already know how to open and write text files, which I do not know how to read a string in a text file and execute certain commands
