Re: [Dev-C++] capture command line output

Hi Noorez,
 
This is a case of redirecting cout (stdout) and/or cerr (stderr) to an input stream.  This is something I've never tried, to be honest.

A simple way would be to output redirect (>) the output of the command line program to a temporary text file, then import and display the text file in your GUI, deleting the text file after capture.
 
BTW: insight.exe probably uses this capability, as it's actually a GUI shell for GDB.  So it's source may be helpful.
