Executing Commands from a Command Line to External Program

[workboy]

Hello,

I am trying to input lines of code into a command line for a program from C++. I have read up on the system command, however, my main problem is once I open the command prompt, I would like to pass a line of code to the command prompt from the C++ code. My algorithm is as follows:

1. Open command prompt using C++
2. Start the executable program file using C++
3. Pass a file name from C++ code to the command prompt of the executable to open the file within the external program.

If there are any suggestions, as always I would be very grateful. Thank you.

Why not use a function like CreateProcess() ?

Hi Zaita, I'm not sure how to use CreateProces(). Can you expand on it for me? Thank you
