  2. IP Configuration Batch File

    This is a batch file I use to automatically reconfigure my Ethernet port when I move from one network to another.
    It starts by finding and displaying the current address of the card and then displays a menu of IP addresses from which you can select. Once you have selected the address you want from the menu (1-5 for this file), it changes to that address and then verifies the new address and displaying it. If you enter an invalid selection, it will dump and start over without changing anything.
    This utility is based off of Microsoft's NETSH and SET commands.
    I keep this file, along with all my other batch files, in the subdirectory C:\Batch Files. I then have a shortcut on my desktop to call it.
    To modify, I prefer right-clicking on the batch file and selecting "Edit". For me, this brings up Notepad (my default editor) and make for easy modifications. Obviously you will need to update it to match your IP addresses, but you may need to modify the reference to "Local Area Connection" to the specific adapter name on your laptop.
    FYI - I am currently running this on WinXP.

  3. AutoPlay for CDs (autorun.inf)

    if you have tried to make own cd with autoplay you may have noticed that
    AUTORUN.INF only works on executables (exe or bat for example) but what if
    discs with data you want to share with customers for example only contains documents
    like presentations spreadsheets PDFs etc.?
    one can easily make BAT file with START "MY_DOCUMENT" but the downside is
    that command line box shows up during loading etc.
    there are numerous programs on the internet that can take care of that but
    all i was able to find was not free (well it could be there i didn't look too hard).
    this is why this little program is made. it is based on ShellEx API
    it's simple to use simply specify inside INI file what document you want to open when disc is inserted
    and edit AUTORUN.INF to be something like this:
    [AutoRun]
    OPEN=AutoPlay.exe
    ICON=Icon.ico
    note that AutoPlay.exe looks in AutoPlay.ini for line OPEN=
    and file name should be enclosed by quotation marks
    for example OPEN="My Presentation.ppt" or "New Developments.pdf"
    also AUTOPLAY.INI must be in same folder as AUTOPLAY.EXE
    to make your disc start properly when inserted you need:
    1. AUTORUN.INF
    2. AUTOPLAY.EXE
    3. AUTOPLAY.INI
    4. end user PC that don't have autoplay feature turned off (sorry can't control everything)
    and before i forget:
    AutoPlay.exe does not handle your files. it simply tells Windows to open them.
    in other words target pc should have installed software to handle specified file type or
    the moment of glory will be...well without glory...
    good luck
