    Joining files

    Hi group,

    I have an app that streams files over the network. What I want to be
    able to do now is select a folder and stream the entire contents of
    that folder over the network. I could simply just loop through each
    file and transmit them one at a time but I would rather somehow stream
    all the files into a single file and then transmit this one file. Upon
    receipt, then "un-stream" all these files. Something similar to the
    TAR command on unix. Compression as well would be a plus but I am not
    that bothered.

    However, my problem is that I am distributing the .exe without any
    install. Because of this I cannot use any third party DLL's or
    add-ins, so all/any code must be VB and compiled into my .exe

    I saw that there is zip library made in C# which is no good because I
    cannot add a C# project to my solution, nor include an extra DLL. Does
    anyone know if this project was translated to VB? If not, any ideas,
    help at all?

    TIA,
    Hugh

    p.s. I am using VB.NET 2003. I read somewhere that .NET 2.0 framework
    has a class for this but I am stuck with version 1.1 !

      Hi,

      If you use the sharpziplib you would not have to register the
      dll just copy it to the directory with your exe. A setup program would not
      be needed.

          Thanks Ken, I had originally thought of this but one of the
          requirements of the app is that it is all contained in 1 exe and has no
          dependencies at all. So that rules sharpziplib out I am afraid.
          I am guessing I want to stream the contents of all the files into 1 big
          file. And then work out how to get this info back out. Is this even
          feasible? I am totally stumped on this problem.

              Maybe you could 'read' all the files into one big byte array, then create a
              memory stream from this byte array.... just a thought, but watch out for
              memory usages.
