Horrible hacky way:

Yes, when you want to run the program, set it up instead to run:

cmd /c myapp.exe < data.in > result.out

or if you're using the older family of 32 OS's then do

dosprmpt /c myapp.exe < data.in > result.out

and that should do the trick - you need to use the part of the "run"
dialog that allows you to execute an arbitrary executable.

You'l have trouble debuggin your own app.

Nice pleasant way:

get your program to take command line parameters, and get it to do the
file I/O itself.
