im making a packet analyzer tool. im using sharppcap for packet capturing. the problem is i cant decompress Content-encoding:Gzip data from the packet. when i try to decompress the packet using gzipstream it gives me magic number in header is incorrect.
View 1 RepliesI have a device with an embedded webserver that accepts URL-based commands and queries. The device provides a user-privilege schema, so I have administrative accounts, operator accounts, and plain user accounts. Certain commands and queries require authorization via username and password to establish the privilege level available.

I'm looking at a website using Internet Explorer and Firefox. In each browser I select view source and see the website's URL in the links. These links were concatenated together using HttpContext.Current.Request.Url.Host in the code behind. However, when I use netcat or Burp Suite v1.3.03, looking at the same links I see the servername instead of the website's URL.
My question is - Why does view source in the browser display different links in the page source than what netcat or Burp Suite outputs? Is the browser rewriting stuff? My thought to correct is to have a web.config setting which is used to create the links. Next question - Does anyone know of a configuration change to make to IIS to return the URL instead of the server name or a .NET function that I should be calling instead to get the URL that the website is running as.
Background: I have read a bunch of techniques to handle compression. I don't think SmartZipLib handles 7z. System.OS.compression does not seem to handle rar or 7z. I am trying to find one approach for all.The tools within Windows XP seem to handle them all from inside the file manager (at least on my computer).Question: how can I decompress all these files using the windows utility? I am guessing it is some sort of Shell command. Alternatively, is there another option?
View 2 RepliesI 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
View 1 RepliesWe 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).

This is the first time I am working on compressing and decompressing data. I have a byte array(a dataset before compression) which is an already compressed data and I want to decompress it. But the decompression is to be done in .Net Compact framework 2.0 and this framework doesn't have System.IO.Compression library to use GZipStream or DeflateStream.
View 1 RepliesI would like to decompress/compress text files in zlib format.
Here's what I tried:

This files are textfiles created from flash with ActionScript 3.0, but compressed, using the ByteArray class's compress() method. I know Flash uses zlib algorithm for this, and I would like to open and use this file from vb.net.

FileOpen(1, OpenMapDialog.FileName, OpenMode.Binary, OpenAccess.ReadWrite)
Dim a() As Byte = {}
FileGet(1, a)

How do I decompress a zlib compressed file with byte arrays?
I am just experimenting with loading images into a picture box. I have a modest size image (1024 x 768). If I time how long it takes to load some images from disk and display into a picturebox diagnostics.stopwatch) it takes less than half the time to load a bitmap than a jpeg. The jpeg is 50k or so and the bitmap about 2 meg in size. So the read time from disk would be slower for the bitmap but decompressing the jpeg is obviously the really taxing part for my machine. Nvidia cards and the like have some really fancy hardware on them so I am wondering if there is a way to offload the jpeg decompression into the graphics card's expensive gpu making the whole process quicker: faster read from disk and faster displaying of the image. I had a look at a direct x tutorial that simply loaded an image as a sprite and it took ages. I am obviously approaching it from the wrong point of view.
View 5 RepliesI'm coding in vb.net, and I haven't in forever so I'm a little rusty now.I want to be able to post data to a website, it can be anything as long as it can call the url (without being in a browser).[URL]
View 1 RepliesI have developed an application for Windows Mobile Devices using Visual Basic 2008. One feature of the application, allows users to view records that are stored online, on the device. The application sends encoded data to an API, which is simply part of a server. The process I am using to send the data to the API is extremely simple. When you press the "Send" button in the application, it pulls the information needed, encodes that information in base64, and then attaches that information to the end of a URL. For example, it would look exactly like this when it was ready to send.
[URL]
The data is then sent out by simply loading it into a webbrowser control. Once the data hits the API, the API Then sends a response back. And this is where my issue is coming into play. The API either sends a message back saying "Pass" or "Fail". If it Fails, It includes and Error Message. If it passes, it includes a "URL" which then has to be opened in a browser or in a webbrowser control.
I need to know: HOW DO I CAPTURE THE RESPONSE THAT THE API IS SENDING BACK. More Specifically, I need to know how to capture the URL that is being sent back from the API, so that I can open it in a webbrowser control.
Now, I feel like I need to be more specific as to what is going on. I am able to send the data to the API, and it is being sent exactly as it needs to be. It has been confirmed on the API side, that the response is being sent back to me. The only problem I am having, is trying to figure out what to do with the response, more specifically, how to view the response period. I'm extremely new to the entire API Deal. Without being able to view the URL That is being sent back, the feature doesn't work of course.

I am using Async socket class to handle HTTP data. The OnRecieve event handler looks like this:
Private Sub sck_onDataArrival(ByVal sData() As Byte, ByVal BytesTotal As Integer) Handles sck.onDataArrival
Try
Dim ms As New IO.MemoryStream(sData)
Dim returnImage As Image = Image.FromStream(ms)
Picturebox1.Image = returnImage
Catch ex As Exception
Debug.Print(ex.ToString)
End Try
End Sub
I realize this will not work because the byte array still contains the header information from the response from the server. How to strip this data without converting the byte array to a string. I need to strip the header response information and just be left with the image data and from there convert that data into a stream so the stream can be loaded into an image and displayed in my picturebox.
I have a program, and a string is generated. something like:
TAG POS=1 TYPE=INPUT:TEXT FORM=NAME:NoFormName ATTR=NAME:movie_imdb CONTENT= [URL]
TAG POS=1 TYPE=INPUT:TEXT FORM=NAME:NoFormName ATTR=NAME:movie_urls[] CONTENT=[URL]
Now I need this to be:
TAG POS=1 TYPE=INPUT:TEXT FORM=NAME:NoFormName ATTR=NAME:movie_imdb CONTENT=[URL]
TAG POS=1 TYPE=INPUT:TEXT FORM=NAME:NoFormName ATTR=NAME:movie_urls[] CONTENT=[URL]
v=ACFXQPGT
I know this might look easy, but I already trid so much but it doesn't work.
Now I was trying a regex:
Dim pattern As String = "CONTENT=|?http"
For Each m As Match In Regex.Matches(Data, pattern)
MsgBox(m)
Next
But I don't know what the "|?" or pattern should be.
I have coded very simple asp pages to return an image when requested. But I need to do this from a vb.net application. So I assume I need to create a mini http web server. I have code for some that does not support asp or anything like that. Is there another method to return an image? Anyone have an example of this? Or again, do I need to find a web server control or app to use?

My application was designed in Visual Basic 08. There is a feature in the application that allows users of the app, to view a "Recording" page from the application, and works with a Soap API. Once the application sends the requested data to the API, the API responds with a custom URL, which must then be opened in a browser.How do I capture the response, or to be more specific, the URL that is being sent back from the API? Below, I have included the full parameters of the api, as well as the code that I have so far. What I really need to do, is figure out how to caputure the URL that is being sent back from the API to a text box. This will allow me to then transfer that text to the browser. But again, I have listed the full specifications, or parameters of the api below, as well as the code that I have so far. In case it helps, the app was designed for Windows Mobile using Visual Basic 08. [code] I am able to send the correct information to the api, but when the api returns the response, with the URL in it, I am unable to obtain that URL, and therefore unable to open that URL in a web browser, which has to be done as you can see from the API specs.
