Stream in Stream?

| Hello. I've been meaning to improve file packer and module to read faster. Right now I read a file from a stream and store it in a bank stream. Then I read the contentment's of the file from that bank into a resource. That's BAD.. and slow. I was wondering if there is anyway to create a stream out of another stream knowing the position and the length. Sort of substream:TStream = stream.SubStream(pos,length) Could anyone help me out with this? |

CopyBytes?
Local stream1:TStream = OpenFile("test.txt")'make sure it's got something to read
Local bank:TBank = createbank(1024)
Local stream2:TBankStream = TBankStream.create(bank)
stream1.seek(100)
CopyBytes(stream1, stream2, 1024)
stream2.seek(0)
print readString(stream2,1024)
print stream2.size()

| Nope that's just as bad since the copying is there. I want the second stream to read from the same source. If it helps in any way I just need reading not writing. |

| I'm a little confused by the request then. If you want to read from the same source, can't you just use the same stream? |

| I'm guessing he wants to "separate" the "pack" stream into multiple "file" streams, thus avoiding the copying of the data into separate streams. Not sure if it's possible. |

| Might be possible with a TStreamWrapper? *EDIT* In fact, it looks like ziggy was looking to do something similar: http://blitzbasic.com/Community/posts.php?topic=75366#842156 Last edited 2011 |

| Oh yeah. That's perfect :D Now just gotta figure a way to implement to compression and encryption in that but that's not top priority. Thank a lot guys. |
