  • What's the BPF for HTTP?

    - by Gtker
    The definition can be seen here. The candidate answer may be tcp and dst port 80,but can tcp and dst port 80 guarantee it's HTTP traffic and includes all HTTP traffic? It seems not,because some site can be visited by specifying a different port other than 80 this way: http://domain.name:8080 So my question is: what's the exact BPF for HTTP?

  • What's special about mouse capture and middle mouse button in WPF?

    - by Scott Bilas
    When I call CaptureMouse() in response to a MouseDown from the middle mouse button, it will capture and then release the mouse. Huh? I've tried using Preview events, setting Handled=true, doesn't make a difference. Am I not understanding mouse capture in WPF? Here's some minimal sample code that reproduces the problem. // TestListBox.cs using System.Diagnostics; using System.Windows.Controls; namespace Local { public class TestListBox : ListBox { public TestListBox() { MouseDown += (_, e) => { Debug.WriteLine("+MouseDown"); Debug.WriteLine(" Capture: " + CaptureMouse()); Debug.WriteLine("-MouseDown"); }; MouseUp += (_, e) => { Debug.WriteLine("+MouseUp"); ReleaseMouseCapture(); Debug.WriteLine("-MouseUp"); }; GotMouseCapture += (_, e) => Debug.WriteLine("GotMouseCapture"); LostMouseCapture += (_, e) => Debug.WriteLine("LostMouseCapture"); } } } Generating a default WPF app that has this for its main window will use the test class: <Window x:Class="Local.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:Local" Title="MainWindow" Height="350" Width="525"> <local:TestListBox> <ListBoxItem>1</ListBoxItem> <ListBoxItem>2</ListBoxItem> <ListBoxItem>3</ListBoxItem> <ListBoxItem>4</ListBoxItem> </local:TestListBox> </Window> Upon clicking the middle button down, I get this output: +MouseDown GotMouseCapture LostMouseCapture Capture: True -MouseDown So I'm calling CaptureMouse, which in turn grabs and then releases capture, yet returns true that capture was successfully acquired. What's going on here? Is it possible that this is something with my Logitech mouse driver doing something goofy, trying to initiate 'ultrascroll' or something?

  • Is it possible to tie nested generics?

    - by Michael Deardeuff
    Is it possible to tie nested generics/captures together? I often have the problem of having a Map lookup of class to genericized item of said class. In concrete terms I want something like this (no, T is not declared anywhere). private Map<Class<T>, ServiceLoader<T>> loaders = Maps.newHashMap(); In short, I want loaders.put/get to have semantics something like these: <T> ServiceLoader<T> get(Class<T> klass) {...} <T> void put(Class<T> klass, ServiceLoader<T> loader) {...} Is the following the best I can do? Do I have to live with the inevitable @SuppressWarnings("unchecked") somewhere down the line? private Map<Class<?>, ServiceLoader<?>> loaders = Maps.newHashMap();

  • Capturing system command output as a string

    - by dreeves
    Perl and PHP do this with backticks. For example: $output = `ls`; This code returns a directory listing into the variable $output. A similar function, system("ls"), returns the operating system return code for the given command. I'm talking about a variant that returns whatever the command prints to stdout. (There are better ways to get the list of files in a directory; the example code is an example of this concept.) How do other languages do this? Is there a canonical name for this function? (I'm going with "backtick"; though maybe I could coin "syslurp".)

  • Possibility of initiating playback of flash video on headless server through the terminal

    - by brendan morrison
    Hey so I have a website which has video's gathered from places around the web, primarily youtube but a few other's as well. Now I am wondering if there is some way to check link's to make sure they are still available through a unix shell. (My idea is to run a cron to check videos are still available and if not delete them.) I am aware i could use user to do this but it always bothered me and was wondering if there is somehow to check the playback of a flash video though the terminal . Any insight into this would be awesome as I haven't found much on the web. Also note ideally the tech. will work on all video type's including html5. update So it's occured to me that through the you tube api, I could check the status of the video's coming from youtube (which is a start). But I would love to know if there's something else that is not player specific but rather just calls the video to play similar to how a user would.

  • java packets byte

    - by user303289
    Guys, I am implementing a protocol in one of the wireless project. I am stucked at one point. In of the java file i am suppose to receive a packet and that packet is 12 byte packet and I have to write different functions for reading different parts of packets and convert it to diferent type. Like I want first four byte in one of the function and convert it to int, next two bytes in string. and again next two in string, last two hop in string and followed by last two int. I want follwing function to implement: // here is the interface /* FloodingData should use methods defined in this class. */ class FloodingPacket{ public static void main(String arg[]){ byte FloodingPack[]; // just for example to test in code FloodingPack=new byte[12]; interface IFloodingPacket { // Returns the unique sequence number for the packet int getSequenceNumber() ; // Returns the source address for the packet String getSourceAddress(); // Returns the destination address for the packet String getDestinationAddress(); // Returns the last hop address for the packet String getLastHopAddress(); // Sets the last hop address to the address of the node // which the packet was received from void updateLastHopAddress(); // Returns the entire packet in bytes (for sending) byte[] getBytes(); // Sets the bytes of the packet (for receiving) void setBytes(byte[] packet); }

  • How can I edit a js file sent by the server before it gets to my browser?

    - by pstone
    During a normal browsing session I want to edit a specific javascript file before the browser receives since once it gets there it's impossible to edit. Is there are any tool for this? For what I need it I can't just save it and edit it on my disk. I'm ready to learn how to program it myself but if anyone can point out more or less what I have to do I'd be very grateful. I'd have to intercept the packets until I have the whole file while blocking the browser from receiving it any part of it, then edit it manually and forward it to the same port. I don't think I can do this by just using pcap, I've read a bit about scapy but I'm not sure if it can help me either. Thanks in advance.

  • Detecting video playing in browser from a screenshot -- OpenCV

    - by Jon
    I would like to draw a rectangle around a video playing on my screen. For example, I am watching a YouTube video in my browser. I would like to be able to take a screenshot, analyze that screenshot, and then draw a rectangle around where the YouTube video is playing. I have just started looking into how I might be able to to this. I came across OpenCV. I understand that OpenCV covers many computer vision techniques. Would any of them be particularly well suited for this task? Also, is this something that can be done in real time? Finally, is there a technique that would work for both in browser and full screen? Thanks!

  • Which regex flavors support captures (as opposed to capturing groups)?

    - by Tim Pietzcker
    As I just learned from this question, .NET regexes can access individual matches within a repeated capturing group. I. e., if I apply a regex like \b(\w+\s*)+ to a string of words, only the last word will be stored in \1 or Match.Groups(1).Value, but using Match.Groups(1).Captures I get access to all the individual matches the regex iterated over. Are there other regex flavors that support this besides .NET?

  • How to Generate Spritesheet from a 'problematic' animated Symbol in Flash Pro CS6?

    - by Arthur Wulf White
    In the new Flash Pro CS6 there is an option to generate spriteheet from a symbol. I used these tutorials: http://www.adobe.com/devnet/flash/articles/using-sprite-sheet-generator.html http://tv.adobe.com/watch/cs6-creative-cloud-feature-tour-for-web/generating-sprite-sheets-using-flash-professional-cs6/ And it works really well! An artist I'm working with created a bunch of assets for a game. One of them is a walking person as seen from a top-down view. You can find the .fla here: https://docs.google.com/folder/d/0B3L2bumwc4onRGhLcGNId1p2Szg/edit (If this does not work let me know, it is the first time I used Google Drive to share files) 1 .When I press ctrl+enter I can see it is moving. When I look for the animation, I do not seem to find it. When I select to create a spritesheet, flash suggest creating a spritesheet with one frame in the base pose and no other (animation) frames. What is causing this and how do I correct it? 2 .I want to convert it to a sprite sheet for 32 angles of movement. Is there any magical easy way to get this done? Is there a workaround without using Flash CS6 to do the same thing?

  • VMWare Lab Manager: What's the difference between Capture to Library and Archive to Library?

    - by mcohen75
    On a configuration in my workspace I have two options, Capture to Library and Archive to Library. What's the difference between the two? The Lab Manager User's Guide isn't very useful here: Archive a Workspace Configuration to the Library You can preserve the exact state of a configuration in the configuration library. Archived configurations are read-only, but you can clone, export, and delete them. Sounds like what Capture to Workspace does.

  • How to capture the screen in DirectX 9 to a raw bitmap in memory without using D3DXSaveSurfaceToFile

    - by cloudraven
    I know that in OpenGL I can do something like this glReadBuffer( GL_FRONT ); glReadPixels( 0, 0, _width, _height, GL_RGB, GL_UNSIGNED_BYTE, _buffer ); And its pretty fast, I get the raw bitmap in _buffer. When I try to do this in DirectX. Assuming that I have a D3DDevice object I can do something like this if (SUCCEEDED(D3DDevice->GetBackBuffer(0, 0, D3DBACKBUFFER_TYPE_MONO, &pBackbuffer))) { HResult hr = D3DXSaveSurfaceToFileA(filename, D3DXIFF_BMP, pBackbuffer, NULL, NULL); But D3DXSaveSurfaceToFile is pretty slow, and I don't need to write the capture to disk anyway, so I was wondering if there was a faster way to do this

  • When debugging on WinCE, how can I set Visual Studio to always load symbol files it knows about?

    - by tsellon
    I'm debugging a WinCE, C++ program in Visual Studio across an ActiveSync connection. Every time I start the process it fails to load symbol information. However, if I right click on the module and hit 'Load Symbols' it correctly locates the symbol information without any further prompting from me. Is there a way that I can set Visual Studio to either: (a) automatically load this symbol information, or (b) automatically break the process into the debugger once it's loaded (similar to what windbg does)? I'm guessing there's a setting somewhere, but I've yet to find it. Update: I forgot to mention in the original question that I'm not debugging with the instance of Visual Studio that created the exe.

  • How do you update the server name in source indexed symbol file?

    - by Keith Hill
    With the Debugging Tools for Windows you can run SSIndex.cmd against your symbol files and it will embed the command to retrieve each source code file from the TF server. We have a bunch of indexed files and recently our IT migrated our TFS 2008 installation to TFS 2010 and in the process changed the server name. Question is, how can I update all these symbol files to point to the new server? I thought SSindex used an alternate data stream named 'srcsrv' but SysInternals' streams.exe shows nothing on these symbol files even though srctool.exe shows the data.

  • Why a revert a file in EGit, but the dirty symbol '<' still exist in the project view?

    - by Happier
    I try EGit revert for several days, It's very confuse that when I revert the file following the user guide, and I still got the file dirty symbol in the related file. http://wiki.eclipse.org/EGit/User_Guide#Reverting_Changes I choose 'Replace with' - 'File in Git Index', it works, the content has been revert, but the symbol stays the same, sometimes, the symbol will disappear after a while, but sometimes, it didn't disappear. I'm using eclipse on windows, I'm not sure it's about the '\r\n' character. But I use 'Compare with ' - 'File in Git Index', two files look the same. Hope someone can tell me why, I think it can be a bug? Thank you in advance.
