    Very large string

    I'm reading the response to the DOS "FIND" command into a string. Until
    now it has worked just fine. Now it's returning so much data that the
    string seems to be full. Here's a snippet of the last few lines:

    ---------- C:\PROGRA~1\VER ITAS\BACKUP~1\N T\DATA\BEX22845 .XML: 0
    ---------- C:\PROGRA~1\VER ITAS\BACKUP~1\N T\DATA\BEX22851 .XML: 0
    ---------- C:\PROGRA~1\VER ITAS\BACKUP~1\N T\

    How much can a string hold? Will a StringBuilder hold more? How would I
    use a string builder in this case?

    Thanks.

      Hello Terry,

      Speaking out my ass here, so be sure to research what I say.. But I believe
      the string data type is limited in capacity only by the amount of available
      memory. However, strings are immutable.. so modifying them, especially large
      ones, is quite expensive. A string builder will certainly increase the speed
      with wich you can modify strign contents.

      Looking up string builder in the MSDN docs will get you started in their use.

          How do you build the string?

              As addition to Boo,

              And therefore will a sentence as

              A = A

              Direct a memory overflow as A is longer than half of the memorysize (as long
              as this inside the 2Gb area of course in 32Bit systems).

              Just something I was thinking of reading Boo's message.

                  Using the Tivoli RemoteExec service on the remote server. I connect via TCP,
                  send the DOS command, and the response is returned. Like so:

                  dim str as string
                  str = RmtExec.Send("F IND /C /I "Text to find" c:\directory\*. xml)
