pipeline in c++

I don't get you, what do you mean by pipeline here, run another process along with a running one? Use threads for that purpose?

Ipc ?

in other words call another prog fron one(exe only)

Click to expand...

If you just want to execute one program from inside another, use the system() call.

Auto Gordian Knot is best example of what i want to say....it calls several other progs one after another.i want something like that...say i want to start winamp from my prog how would i do it?


As for using system() is it through "cmd"?

One after another is easy. Yes, use system() call, system("command -args")

Where command can of course, be any executable on Windows. Even Winamp, just give the full path to it.

system(call thatfile.exe)

ok....thanks a lot...
