console input/outpu

**keeper** · 03-11-2006

Hi,

I search for an example how to interact with the cmd of windows. all commands I sent to my programm should go to the cmd and the response from the cmd back to my programm and so back to the user.

So when I type in my programm dir c:\ this command should go to the cmd and the response (the dir listing) back to my prog.

Thx for any ideas?

One way would be to pipe the output of cmd to a file.

To build off of your example:
When you type
dir c:\
in a command-prompt you will get a big list of all the directorys right. Now if you type this instead:
dir c:\ > c:\result.txt
You wont see anything. The output will be stored in a textfile for you.

This way you can then in your own program read all that in and do whatever you want. To do this in a program you can do something like this:
system("dir c:\ > c:\result.txt");

There are probably better ways but this should get you started.

Code:

system("dir c:\ > c:\result.txt");

->

Code:

system("dir c:\\ > c:\\result.txt");

If you don't mind running your program from a command prompt, you can do this (which redirects the output of one program, dir, into the input of another, program):

Code:

C:\>dir *.c | program

Then you just read from the standard input (ie, cin).

For example I have an console application and I use this pipe thing then my programm get startet with the output of the other programm, so I can use it. But my application is a dll

, any ideas how to do it in that case? And the application under which my dll runs I can't change so theres no way to get the output to the exe and then to the dll!

Well then look at my first example. Or better yet use opendir()+readdir()+closedir() to achive what you want. http://faq.cprogramming.com/cgi-bin/...&id=1044780608
