I'm wanting to make a program to rip dvd's but more importantly to store them so the user can watch them when they want. To keep the cpu's memory down I figured I can compress the dvds when the person just has them sitting there and then decompress them when the user wants to play them. I've kinda looked into gzipstream, but would that really work? Should I take a different route?
View 6 RepliesI'm currently working on a utility software, file compression, with VB.Net. And using an open source library to compress and decompress files - DotNetZip - and already running.
My friend told to make it unique and not traditional, that I make the output compressed files cannot be opened with other compression software. Now my question is... is it possible that way? Using an open source library which the output format is ".zip"?
I first thought that changing the file extension of the compressed file to unknown format so it can't be opened when you try to decompress it, unfortunately, using the "Open With..." function of windows it could still be decompressed.
Is it really possible? OR what other features can I add that WinZIP doesnt have yet? I compared my work to WinZip since the same output is ".zip".

Alternatively, code to conditionally redirect to the same page on another site (could create another virtual site with compression disabled) but need to pass all parameters (GET/POST).

View 9 RepliesI have a WCF Windows service that provides data to 250+ PDAs via compressed datasets and was looking to redevelop both the service and the mobile application to use Entity Framework 4.x models. In order to keep performance acceptable when sending/receiving data on the PDA I need to keep the data size as small as possible and was wondering if its possible to compress a IEnumerable from the WCF windows service? From previous experience with the datasets I got a 80%+/- compression rate and even decompressing the data on the PDA achieved an overal 50% performance importment so retaining similar levels of performance is critical. Could I use a binary serializer and then compress the stream?

2 List all of the data from Results.txt in the Listbox (use the same Listbox as in 1 above).Include suitable headings. Note that you cannot assume that the file contains onlyresults for the first 3 weeks of the season. Your program should be able to process a results file with more or fewer results.
3 List all of the data from Results.txt in the Listbox. However, in this case the actual team names should be output (your program will need to get this data from Teams.txt. The data should be formatted so that it is aligned correctly. Include suitable headings.
The output might look as follows:

I am using VB for our entire company. Recently, we have had a need to dial into a VT220 to retrieve information from our customers. We are using ZOC terminal and it has a .dll for Visual C that lets us automate ZOC without needing a human interfacing with it.
Does anyone know anyway for a VB application to run a VC file? I highly doubt it and no one here has ever tried something like this, nor have I ever heard of anyone try this before. Just trying to see if this is even possible and if so - how...
Limitation: -We cannot restructure our company using VC (way too large)
Reason: -We import data on a daily basis but do not want to have to have someone remember everyday to run ZOC. In addition, our imports are done before anyone is in house.
