    It was my understanding that spawn simply did not close any files that were open in the parent, but I haven't read anywhere that it can pass the handles of files, just command line arguments that your child process can run. I guess in this way you could pass file names from your parent, but not inherit handles.

    so, is there any other functions i can use to run exe file that inherit handles from its parent prog.

    currently i'm using CreateProcess() to do it but the program won't stop running until user press ENTER button for a couple of times. the program that i've been working on is use to run another EXE file with the list of inputs being supply by the 'input.dat' file and then output from the EXE file will be redirected to 'output.dat' file. hope this can help you out to understand what i'm trying to do.

    so i think maybe i should try other functions to make my program works.
