Does anyone know how to get the output of a DOS program in C++. I have an old program that I use in DOS and I need to get the data it outputs, but I havn't found a good way to do it yet. So if anyone knows please let me know

Dunno if this helps. Can you manage to redirect STDOUT to your program? I think the stream libs supports this. Again, it's only a suggestion. I'm not too familiar with C++.

Hi Scott Just a thought The dos program that you are trying to pick up the output from Is it a program that you have writted ? Is it possable to redirect the output to a file ? e.g > text.doc
or does the information get displayed on the screen from within the program ?
if it is posble to re-drect the output to a file you may be able to read this information into the c++ program as normal
hope it helps
regards Richard

The program is not one that I have written. It displays the information on the screen as part of the program. When I call my program and it runs the dos program it will not let me capture the output using a cin command. After the dos program I get my prompt for input in my program. So I am wondering if there is a screen capture command that would read the screen and put it into some sort of string, from which I could get the needed information Scott

No, what the other guy meant was just do this at the dos prompt:
program.exe >>log.txt
just replace the program.exe with the name of the program you run, it will pipe the output to log.txt. use just > to make a new log.txt everytime.
