Hi, I'm trying to write a program in C++ using VS 2008 that will do some file processing, then call a program called scip (http://scip.zib.de/) and get scip to use a temporary file I have generated. The problem I am having is that once my program has called scip, scip then 'takes control' of the window; when I do this: string scip ("C:\\zimpl\\scip\\scip.exe"); system(scip.c_str()); cout<<"read\"stableset.lp\""<<"\n"; the line sent by cout doesnt appear until I type 'quit' and scip returns control back to my program, which then dumps 'read"stableset.lp"' on the screen. I don't know if it's relevant or not,but when you run scip in the command prompt, the prompt changes from 'C:\zimpl\scip>' to SCIP\> If anyone knows how I can then send commands to scip using my C++ program I'd be very grateful. Thank you.

The problem I am having is that once my program has called scip, scip then 'takes control' of the window That's how system() works, yes. get scip to use a temporary file I have generated Does this 'scip' have a command-line argument to specify this temporary file? If anyone knows how I can then send commands to scip using my C++ program If it uses stdin, I can throw up an example, but it's kind of a pain.

Hi, you can't start up scip with an argument unfortunately, you have to enter commands. I actually need to send it the following: read"stableset.lp" optimize display results as three separate commands. Is there a way to do that? Do I perhaps need to start a separate thread? Thanks

Have found a way round this now (using scip), thanks for your help.
