    Question Background Processes

    Hi! This question has two parts. It involves Visual C++ 6.0 to
    create a program that will be run on various types of Windows
    platforms.

    1. I'm looking for a way to run an executable as a background
    process from inside the program. execl() won't allow this, I
    believe.

    2. I'm looking for a way to stop that same background process
    from inside the program.

    I haven't found anything yet and any help any of you might give
    would be appreciated.

    Thanks!

    one simple way is to pass an HWND as a command line parameter and PostMessage back and forth between windows (the background window can be hidden).

    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    Unfortunately the executable we are using is proprietary
    software. I can't modify the handle of this program. It's
    already set up to be a windows app.

    It wouldn't be so much of an issue if we could trust
    everyone not to kill it....

    Ok, I'm going to try that and see if it will work with this
    App.

    Thanks much!

    CreateProcess worked wonderfully. Of course now I can't get rid of the process I created. It creates two processes:

    VCSPAWN.exe and
    <program.exe>

    VCSPAWN.exe goes away when the program exits but the
    other program stays.

    I've tried ExitProcess, TerminateThread ( I know to stay away
    from TerminateProcess). The only thing I get out of
    GetExitCodeProcess and GetExitCodeThread is the number 259.
    Doesn't matter what I do. The examples I've seen when using
    ExitProcess have been in the 0 - 1 range. Something is very
    wrong here.

    Help!
