Hi, I am trying to get input from another program, text, then have my program use that to go on from there. How would you get the input from the other program tho? I tried but never got it to work by using "<iostream>" but I didnt get it to work right on my end b/c I only know how to get it from a file.
just pipe the data to your program from the command prompt:
C:\prompt> producer | consumer
Is there another way? I never did much with the command prompt, I do mean in c++ also. I am getting what I say from another program, not one I made.
Create a windowless application, and then just get and parse whatever is given via the message loop
if the producer is sending it's output to stdout, you could use popen (often deprecated as _popen) to read the data from stdin using standard C calls (fgets, etc).
You could use an intermediary process to create the two processes and monitor the sending / recieving data between both applications. There's another idea for you.
You could create a file with this data you want to send (a temp file), and then have the second application read from that file. You could convert the data to a char array and just pass that data into the program (via the pipe operator Sebastiani was talking about, which I highly suggest you spend time -learning- that operator because it will save you an ungodly amount of time), and that will put it into the char *argv[] array, should be *argv[1] if I remember right. You could put the pathname of the temp file you created and pipe the pathname into *argv[1]. Basically...there's a ton of ways you could do this, each with their own special little advantages.
You could initiate the IInd program from the first and pass inputs as parameters to it. Theres some thing in the FAQ.
