    Synchronized Scrolling between C# applications

    What is the best way using C# .NET 1.1 to have two (or more)
    applications perform a "synchroniz ed" scrolling? These applications
    will all be C# .NET and will be on the same machine. The effect I need
    to create is if one program enables this "sync" feature, other
    instances of this application will scroll in sync while the base one's
    scroll bar is moved. Is remoting the best way to do this? Or is there
    another way? I'm just concerned about the amout of messages that occur
    on a scroll event.
    Thanks in advance.

      If this is only supposed to sync one way then it would be possible to on
      scroll, send a windows message to the other application to cause it to scroll
      too. I'm not sure exactly what the code would look like but it sounds
      reasonable to me. I'm sure there are some people more familiar with Win32 to
      shed some light.

          So, is it possible to use windows messaging via .NET? That was
          something I was wondering about.

              Hi,

              It is possible, but you need to use one of the SendMessage or PostMessage API
              functions, AFAIK:

              [DllImport("user 32.dll")]
              public static extern int SendMessage(Int Ptr window, uint message, IntPtr
              wparam, IntPtr lparam);
