Asp.net - Disable GZIP Compression For IE6 Clients?
May 5, 2009
We need to conditionally disable GZIP compression if user's browser is IE6 (it hangs browser for 5min) in few pages of larger site. Server is IIS7 and has compression for static content turned on - want that compression left working if user agent is not Mozilla/4.0. ASPX code sample anyone? 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).

I am running a website using IIS6 and i wrote a simple generic handler which return smaller images when it receive image url as query string. My problem is that the server is applying gzip to some file types such as .aspx and .ashx.And that made my response image from the handler appear with lower quality because they are compressed

How do I create 7-Zip archives with .NET?
I'm looking for ways to do compression and decompression in 7z format via code in VB.NET and C#. Is there any library or .Net code for this purpose?
I know there are GZipStream and DeflateStream in .Net but I want 7z format for better compression ratio.

I'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".

I'm trying to compress a file in .NET, but having some trouble. The zip file is created, but it's only 1KB and no files are within the zip file. Basically, it's not working for some reason and I'm not sure why.
Public Sub CompressFile(ByVal fileName As String)
Dim strOutput As Stream = File.Create("zippedFile.zip")
Try
Using (strOutput)
Dim strInput As Stream = File.OpenRead(fileName)
Using (strInput)

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?

How can I make a program that stores multiple files in one big file (for transporting). There is no need for compression(takes too long).
also, would it be able to open them in this same program (like a windows explorer folder)?

I 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?

I am confused what will happen, when I disable a timer. Will it finish the process and then disable or will it immediately disable without completing process? for example
[Code]....
I want to run getMessage from somewhere else, so I need to disable timer during that time to be asured not to override anything and also before timer disable it should complete that function code.

can we unzip a zipped folder using microsoft APIs or namespaces perhaps System.IO.Compression. However, it seems to be cumbersome to use them. With a thrid party dll file it works perfectly fine, however i dont want to use it as we dont know what is actually happening inside. Can we have a piece of code which unzips a zipped folder.

XML is used as one of our main integration points. it comes over by many clients at a time but too many clients importing at the same time can slow down our database to a crawl. Someone has to have solved a problem like this. I am basically using VB to parse through the data and import what i want and don't want.

I'm developing an application, which will have a common db in a server (SQLServer db) and the client PCs will have my program installed - in a LAN.
So, my question is, when the users in the client PC wants to pass some messages (for eg: one of the user got a message from his boss that all of them are requested to meet him). That is, I want to implement a communication system through my app. It will be a common message system. That is, just like a shoutbox.
So, do I have to use a TCP based communication system or just use a timer to check the db for any new messages and display them ?

(Using vb 2008 express.)
I am trying to create a server to send clients text on request. I am using a tcp listener to accept clients then send each client to a thread in a threadpool which deals with each client's request then closes the client connection. It seems to work fine but I would like to know how it works. Using the listen loop below I cant help feeling I should be sending some values to the threaded sub. How does it know which client each thread is dealing with?
Sub ListenLoop()
Looop:
Client = Server.AcceptTcpClient

with XP and Outlook it works perfect, with Vista it does not.
Any chance to get it running on all clients? The source is very simple.
Trying to send some Input data using mailto.
Always works, but on some clients everything is in the subjet and not in the body! Other clients seem to be ok.[code....]
