  • Differnce between linux write and sendfile syscall

    - by JosiP
    Hi Im programming webserver (C), which should send big files. My question is: What are the main differneces in two syscalls: write and sendfile. Does sendfile depends on size of socket system buffer ? I noticed that write often writes less then i requested. For example, if got many requests for one file: should i open it, copy into memory and use 'write', or maybe i can do 'sendfile' for each client ? thx in advance for all answers

  • Unable to Access Localhost after starting Xampp

    - by user7370
    OS: Windows XP Professional, SP 2. Few days back i had xampplite 1.7.1 installed and was able to access localhost and phpmyadmin through browser...... Today it suddenly stopped working. In firefox after i type http://localhost/ nothing happens, just blank white screen. I removed all the files in xampplite folders and re-installed ver 1.7.1 again, it's of no use. Then i installed xampplite 1.7.2 (latest), which i had downloaded from xampp website, again it's of no use. Apache and MySql are running though. I tried using locally installing wordpress, as i have a theme ready and want to convert that design to wordpress, test it and start using it online. Running 'Port-check' on xampp control panel showed this -- RESULT ------ Service -- -- Port -- -- Status -- --------------------------------------------------- Apache (HTTP) -- 80 -- C:\xampplite\apache\bin\httpd.exe Apache (WebDAV) -- 81 -- free Apache (HTTPS) -- 443 -- C:\xampplite\apache\bin\httpd.exe MySQL -- 3306 -- C:\xampplite\mysql\bin\mysqld.exe FileZilla (FTP) -- 21 -- free FileZilla (Admin) -- 14147 -- free Mercury (SMTP) -- 25 -- free Mercury (POP3) -- 110 -- free Mercury (IMAP) -- 143 -- free Mercury (HTTP) -- 2224 -- free Mercury (Finger) -- 79 -- free Mercury (PH) -- 105 -- free Mercury (PopPass) -- 106 -- free Tomcat (AJP/1.3) -- 8009 -- free Tomcat (HTTP) -- 8080 -- free --------------------------------------------- I also Have skype installed but it's not using 'Port 80' (as i have read, this was the issue, but checked under skype option the port is 65013). And when i run file:///C:/xampp/htdocs/index.php - it shows "Something is wrong with the XAMPP installation :-( " Please help with this problem. thanks Sharath kumar

  • Capture Highlighted Text from any window using C#

    - by dineshrekula
    How to read the highlighted/Selected Text from any window using c#. i tried 2 approaches. Send "^c" whenever user selects some thing. But in this case my clipboard is flooded with lots of unnecessary data. Sometime it copied passwords also. so i switched my approach to 2nd method, send message method. see this sample code [DllImport("user32.dll")] static extern int GetFocus(); [DllImport("user32.dll")] static extern bool AttachThreadInput(uint idAttach, uint idAttachTo, bool fAttach); [DllImport("kernel32.dll")] static extern uint GetCurrentThreadId(); [DllImport("user32.dll")] static extern uint GetWindowThreadProcessId(int hWnd, int ProcessId); [DllImport("user32.dll") ] static extern int GetForegroundWindow(); [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = false)] static extern int SendMessage(int hWnd, int Msg, int wParam, StringBuilder lParam); // second overload of SendMessage [DllImport("user32.dll")] private static extern int SendMessage(IntPtr hWnd, uint Msg, out int wParam, out int lParam); const int WM_SETTEXT = 12; const int WM_GETTEXT = 13; private string PerformCopy() { try { //Wait 5 seconds to give us a chance to give focus to some edit window, //notepad for example System.Threading.Thread.Sleep(5000); StringBuilder builder = new StringBuilder(500); int foregroundWindowHandle = GetForegroundWindow(); uint remoteThreadId = GetWindowThreadProcessId(foregroundWindowHandle, 0); uint currentThreadId = GetCurrentThreadId(); //AttachTrheadInput is needed so we can get the handle of a focused window in another app AttachThreadInput(remoteThreadId, currentThreadId, true); //Get the handle of a focused window int focused = GetFocus(); //Now detach since we got the focused handle AttachThreadInput(remoteThreadId, currentThreadId, false); //Get the text from the active window into the stringbuilder SendMessage(focused, WM_GETTEXT, builder.Capacity, builder); return builder.ToString(); } catch (System.Exception oException) { throw oException; } } this code working fine in Notepad. But if i try to capture from another applications like Mozilla firefox, or Visual Studio IDE, it's not returning the text. Can anybody please help me, where i am doing wrong? First of all, i have chosen the right approach?

  • Get audience members using web services in SharePoint

    - by Robert MacLean
    Using the SharePoint API (the one with the assemblies you add, but requires you to run on the server) it is easy to get audience members: using (SPSite site = new SPSite("http://localhost")) { ServerContext svrContext = ServerContext.GetContext(site); AudienceManager audManager = new AudienceManager(svrContext); foreach (Audience audience in audManager.Audiences) { ArrayList people = audience.GetMembership(); if (people != null) { foreach (UserInfo user in people) { Console.WriteLine("send email to " + user.Email); } } } However I can not find a web service to do the same thing?

  • Is it possible to email the contents of vim using HTML

    - by brianegge
    I like to view the current differences in the source files I'm working on with a command like: vim <(svn diff -dub) What I'd really like to be able to do is to email that colorized diff. I know vim can export HTML with the :TOhtml, but how do I pipeline this output into an html email? Ideally. i'd like to be able to send an html diff with a single shell script command.

  • How to use Broadcast Receiver in different Applications in Android?

    - by Sebi
    Hi I have here two applications in two different projects in eclipse. One application (A) defines an activity (A1) which is started first. Then i start from this activity the second activity (B1) in the second project (B). This works fine. I start it the following way: Intent intent = new Intent("pacman.intent.action.Launch"); intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP); startActivity(intent); Now i want to send intents bewtween the two activities by using broadcast receivers. In activity A1 i send the intents the following way: Intent intent = new Intent("pacman.intent.action.BROADCAST"); intent.putExtra("message","Wake up."); sendBroadcast(intent); The part of the manifest file in activity A1 that is responsible for this broadcast is the following: <activity android:name="ch.ifi.csg.games4blue.games.pacman.controller.PacmanGame" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> <intent-filter> <action android:name="android.intent.action.BROADCAST" /> </intent-filter> </activity> In the receiving activity, I define the receiver the following way in the manifest file: <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".PacmanGame" android:label="@string/app_name" android:screenOrientation="portrait"> <intent-filter> <action android:name="pacman.intent.action.Launch" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> <receiver android:name="ch.ifi.csg.games4blue.games.pacman.controller.MsgListener" /> </activity> </application> The class message listener is implemented this way: public class MsgListener extends BroadcastReceiver { /* (non-Javadoc) * @see android.content.BroadcastReceiver#onReceive(android.content.Context, android.content.Intent) */ @Override public void onReceive(Context context, Intent intent) { System.out.println("Message at Pacman received!"); } } Unfortunately, the message is never received. Although the method in activity A1 is called, i never receive an intent in B1. Any hints how to solve this? Thanks a lot!

  • Filtered Router Interface

    - by jviotti
    I'm having some problems with a Scientific-Atlanta DPR2320R2. In specific with the WIFI. A few months ago I changed its password and username and now I can't remember. So I tried cracking it with Hydra but it drove things worse. Content of webadmin was rendered partial, and threw lot of errors. I then reseted the router. I found myself abled to browse the web with ethernet-connected pc. Wifi is configured by registering the device's MAC Address, and indeed the router has been reseted and register MAC address were lost. No device could connect to wifi. In fact, the device does not even recognize the network. I tried the pointing to 192.168.0.1 to restablish the MAC's. But I couldn't connect to the router access point. Tried listing up hosts: $ nmap -sP 192.168.0.0/24 Starting Nmap 5.00 ( http://nmap.org ) at 2012-12-11 01:18 ART Host 192.168.0.1 is up (0.0018s latency). Host 192.168.0.11 is up (0.00025s latency). Nmap done: 256 IP addresses (2 hosts up) scanned in 59.62 seconds Then checked 192.168.0.1 was really up by sending pings. It responded to all my pings. I quick-scanned the access point: $ nmap 192.168.0.1 Starting Nmap 5.00 ( http://nmap.org ) at 2012-12-11 01:08 ART Interesting ports on 192.168.0.1: Not shown: 999 closed ports PORT STATE SERVICE 80/tcp filtered http Nmap done: 1 IP address (1 host up) scanned in 6.73 seconds Look the state of the port 80: FILTERED. I'm pretty confused now. Any suggestion would be appreciated. Thanks in advance.

  • iphone Three20 TTMessageController Address Book

    - by Ward
    Hey there, I'm trying to use the TTMessageController from Three20 to send messages through a custom web service. I'm not clear on how I can incorporate contacts from the user's address book. I see the model mock address book in the sample app, but the sample only contains names. Is there a way to set the datasource of TTMessageController to be the address book? Thanks, Howie

  • boost::asio buffer impossible to convert parameter from char to const mutable_buffer&

    - by Ekyo777
    visual studio tells me "error C2664: 'boost::asio::mutable_buffer::mutable_buffer(const boost::asio::mutable_buffer&)': impossible to convert parameter 1 from 'char' to 'const boost::asio::mutable_buffer&' at line 163 of consuming_buffers.hpp" I am unsure of why this happen nor how to solve it(otherwise I wouldn't ask this ^^') but I think it could be related to those functions.. even tough I tried them in another project and everything worked fine... but I can hardly find what's different so... here comes code that could be relevant, if anything useful seems to be missing I'll be glad to send it. packets are all instances of this class. class CPacketBase { protected: const unsigned short _packet_type; const size_t _size; char* _data; public: CPacketBase(unsigned short packet_type, size_t size); ~CPacketBase(); size_t get_size(); const unsigned short& get_type(); virtual char* get(); virtual void set(char*); }; this sends a given packet template <typename Handler> void async_write(CPacketBase* packet, Handler handler) { std::string outbuf; outbuf.resize(packet->get_size()); outbuf = packet->get(); boost::asio::async_write( _socket , boost::asio::buffer(outbuf, packet->get_size()) , handler); } this enable reading packets and calls a function that decodes the packet's header(unsigned short) and resize the buffer to send it to another function that reads the real data from the packet template <typename Handler> void async_read(CPacketBase* packet, Handler handler) { void (CTCPConnection::*f)( const boost::system::error_code& , CPacketBase*, boost::tuple<Handler>) = &CTCPConnection::handle_read_header<Handler>; boost::asio::async_read(_socket, _buffer_data , boost::bind( f , this , boost::asio::placeholders::error , packet , boost::make_tuple(handler))); } and this is called by async_read once a packet is received template <typename Handler> void handle_read_header(const boost::system::error_code& error, CPacketBase* packet, boost::tuple<Handler> handler) { if (error) { boost::get<0>(handler)(error); } else { // Figures packet type unsigned short packet_type = *((unsigned short*) _buffer_data.c_str()); // create new packet according to type delete packet; ... // read packet's data _buffer_data.resize(packet->get_size()-2); // minus header size void (CTCPConnection::*f)( const boost::system::error_code& , CPacketBase*, boost::tuple<Handler>) = &CTCPConnection::handle_read_data<Handler>; boost::asio::async_read(_socket, _buffer_data , boost::bind( f , this , boost::asio::placeholders::error , packet , handler)); } }
