Receiving console output

Question

Is there a way to execute a program and receive the console output in c++ instead of displaying the console window? I am trying to do a command line call but provide a GUI instead of the console output.

Answer 1

You can do this on most systems using popen (or on some compilers _popen). If that isn't versatile enough for your purposes, you'll probably have to do something platform specific (e.g., fork on a POSIX-like system, or CreateProcess on Windows).

Answer 2

You can write stdout to a file instead, and display the file in your GUI. One method for doing that is freopen.

int main ()
{
  freopen ("myfile.txt","w",stdout);
  printf ("This sentence is redirected to a file.");
  fclose (stdout);
  return 0;
}

This redirects stdout to myfile.txt.
