I have the same problem. I would like to run debugger with input file (like program.exe < test.in).
When I put "< test.in" into programs' arguments and run the program (in c::b), then
"c:\...\program.exe" < test.in
is executed but with no effect (like there is no input). Maybe the problem is with that quota " after program.exe.
Maybe someone knows if it is possible in c::b to run program with input file?
