It really depends on how the program is being run, since the runner is the
one that does the mapping. If you are running it from another program you
can use CreateProcess. A goggle search will turn up several examples of i/o
redirection using CreateProcess. As a general solution, you could have the
app parse the command line and do its own redirection.

This with Host application works, 
but i missed somethig in my prev post... i want to be able to set
breakpoints in my code. With host application the execution doesnt
stop at setted breakpoints.

so... to resume 
Is there a way, my app to get its standard input from file, and yet to
be able to set and use breakpoint.

PS: I could load the external file with AssignFile(File, FileName),
and replace all "ReadLn(myVar)" with "ReadLn(File, myVar)", but my app
expect its input to be redirected to it and i want to test this case

Have you tried Attach to Process? (in the Run menu)

HTH,

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.
