  • Get String Instead of Source - Xcode Cocoa

    - by Kevin
    Hello everyone, I have a program that will scan the contents of a website, and display it in a textbox. The problem is that it shows the html source. For example if my html code was: <html> <body> <p>Hello</p> </body> </html> instead of just showing hello, it'll show the code above... How can I get my objective c program to just read the hello, and not the html source.. I was assuming that it was the encoding when reading the website, but I might be possibly wrong.. I would greatly appreciate it if someone could give me a reasonable answer.. Best Regards, Kevin

  • closing MQ connection

    - by OakvilleWork
    Good afternoon, I wrote a project to Get Park Queue Info from the IBM MQ, it has producing an error when attempting to close the connection though. It is written in java. Under application in Event Viewer on the MQ machine it displays two errors. They are: “Channel program ended abnormally. Channel program ‘system.def.surconn’ ended abnormally. Look at previous error messages for channel program ‘system.def.surconn’ in the error files to determine the cause of the failure. The other message states: “Error on receive from host rnanaj (10.10.12.34) An error occurred receiving data from rnanaj (10.10.12.34) over tcp/ip. This may be due to a communications failure. The return code from tcp/ip recv() call was 10054 (X’2746’). Record these values.” This must be something how I try to connect or close the connection, below I have my code to connect and close, any ideas?? Connect: _logger.info("Start"); File outputFile = new File(System.getProperty("PROJECT_HOME"), "run/" + this.getClass().getSimpleName() + "." + System.getProperty("qmgr") + ".txt"); FileUtils.mkdirs(outputFile.getParentFile()); Connection jmsConn = null; Session jmsSession = null; QueueBrowser queueBrowser = null; BufferedWriter commandsBw = null; try { // get queue connection MQConnectionFactory MQConn = new MQConnectionFactory(); MQConn.setHostName(System.getProperty("host")); MQConn.setPort(Integer.valueOf(System.getProperty("port"))); MQConn.setQueueManager(System.getProperty("qmgr")); MQConn.setChannel("SYSTEM.DEF.SVRCONN"); MQConn.setTransportType(JMSC.MQJMS_TP_CLIENT_MQ_TCPIP); jmsConn = (Connection) MQConn.createConnection(); jmsSession = jmsConn.createSession(false, Session.AUTO_ACKNOWLEDGE); Queue jmsQueue = jmsSession.createQueue("PARK"); // browse thru messages queueBrowser = jmsSession.createBrowser(jmsQueue); Enumeration msgEnum = queueBrowser.getEnumeration(); commandsBw = new BufferedWriter(new FileWriter(outputFile)); // String line = "DateTime\tMsgID\tOrigMsgID\tCorrelationID\tComputerName\tSubsystem\tDispatcherName\tProcessor\tJobID\tErrorMsg"; commandsBw.write(line); commandsBw.newLine(); while (msgEnum.hasMoreElements()) { Message message = (Message) msgEnum.nextElement(); line = dateFormatter.format(new Date(message.getJMSTimestamp())) + "\t" + message.getJMSMessageID() + "\t" + message.getStringProperty("pkd_orig_jms_msg_id") + "\t" + message.getJMSCorrelationID() + "\t" + message.getStringProperty("pkd_computer_name") + "\t" + message.getStringProperty("pkd_subsystem") + "\t" + message.getStringProperty("pkd_dispatcher_name") + "\t" + message.getStringProperty("pkd_processor") + "\t" + message.getStringProperty("pkd_job_id") + "\t" + message.getStringProperty("pkd_sysex_msg"); _logger.info(line); commandsBw.write(line); commandsBw.newLine(); } } Close: finally { IO.close(commandsBw); if (queueBrowser != null) { try { queueBrowser.close();} catch (Exception ignore) {}} if (jmsSession != null) { try { jmsSession.close();} catch (Exception ignore) {}} if (jmsConn != null) { try { jmsConn.stop();} catch (Exception ignore) {}} }

  • How to force programs out of swap file when a resources-intensive batch finishes?

    - by sharptooth
    We use employees' desktops for CPU-intensive simulation during the night. Desktops run Windows - usually Windows XP. Employees don't log off, they just lock the desktops, switch off their monitors and go. Every employee has a configuration file which he can edit to specify when he is most likely out of office. When that time comes a background program grabs data for simulation from the server, spawns worker processes, watches them, gets results and sends them to the server. When the time specified by the employee elapses simulation stops so that normal desktop usage is not interfered. The problem is that simuation consumes a lot of memory, so when the worker processes run they force other programs into the swap file. So when the employee comes all the programs he left are luggish and slow until he opens them one by one so that they are unswapped. Is there a way the program can force other programs out of swap file when it stops simulation so that they again run smoothly?

  • Hiding the console window in a system() call

    - by Justen
    Continuing from this question With each system call, the function constructs a set of parameters and sends them off to another program that is just console-based. Is there a way I can make it so that no console window pops up for each call? I've done a search but the ones that aren't a linker issue just aren't working for me. For instance, I tried the _execl call and System::Diagnostics::Process^ myProcess = gcnew System::Diagnostics::Process; but they aren't working. The _execl will bring a console window up, scroll a bunch of stuff (from the program I called I guess), then close the my app and not even do what it was supposed to do. The System::Diagnostics::Process^ myProcess = gcnew System::Diagnostics::Process; doesn't seem to execute what I want either because the output folder that should contain files, contains nothing. So I'm open for ideas.

  • Writing a telnet client

    - by MAC
    HI, I have a device that exposes a telnet interface which you can log into using a username and password and then manipulate the working of the device. I have to write a C program that hides the telnet aspect from the client and instead provides an interface for the user to control the device. What would be a good way to proceed. I tried writing a simple socket program but it stops at the login prompt. My guess is that i am not following the TCP protocol. Has anyone attempted this, is there an opensource library out there to do this? Thanks

  • Considering getting into reverse engineering/disassembly

    - by Zombies
    Assuming a decent understanding of assembly on common CPU architectures (eg: x86), how can one explore a potential path (career, fun and profit, etc) into the field of reverse engineering? There is so little educational guides out there so it is difficult to understand what potential uses this has today (eg: is searching for buffer overflow exploits still common, or do stack monitoring programs make this obselete?). I am not looking for any step by step program, just some relevant information such as tips on how to efficiently find a specific area of a program. Basic things in the trade. As well as what it is currently being used for today. So to recap, what current uses does reverse engineering yield today? And how can one find some basic information on how to learn the trade (again it doesn't have to be step-by-step, just anything which can through a clue would be helpful).

  • What format do I use to store a relatively small amount of user data

    - by wcm
    I am writing a small program for our local high school (pro bono). The program has an interface allows the user to enter school holidays. This is a simple stand alone Windows app. What format should I use to store the data? A big relational data is obviously overkill. My initial plan was to store the data in an XML file. Co-workers have been suggesting that I use JSON files, Access Databases, SQL Lite, and SQL Server Express. There was even a suggestion of old school INI files.

  • How to check code is compatible with Windows 7

    - by Julen
    Hello, We are developing using Visual C# 2008 Express a program based on WPF under Windows XP machines (32 bits). The thing is that we have tried to run the program in two Windows 7 machines, one is 32 bits Windows 7 and the other is 64 bits Windows 7. Under Windows XP everything is fine. In Windows 7 machine, it launches in the 32 bits version altough there is an error when running one functionality (it does not happen in XP). In W7 64 bits it even does not launch. Is this normal? Is not possible to run 32 bit programs under W7 64-bits,even if they execute slower?? How can we check the code is compatible with Windows 7? Thank you very much in advance. Julen.

  • Intercept windows open file

    - by HyLian
    Hello, I'm trying to make a small program that could intercept the open process of a file. The purpose is when an user double-click on a file in a given folder, windows would inform to the software, then it process that petition and return windows the data of the file. Maybe there would be another solution like monitoring Open messages and force Windows to wait while the program prepare the contents of the file. One application of this concept, could be to manage desencryption of a file in a transparent way to the user. In this context, the encrypted file would be on the disk and when the user open it ( with double-click on it or with some application such as notepad ), the background process would intercept that open event, desencrypt the file and give the contents of that file to the asking application. It's a little bit strange concept, it could be like "Man In The Middle" network concept, but with files instead of network packets. Thanks for reading.

  • how to debug MySql stored procs without breaking control flow from application

    - by M.Taha Masood
    Is there a way to do the following: I have a MySQL DB , and there are many stored procs written in it as well. I use MySQL client library in C to connect to this DB and amongst other things , call the stored procedures. Is there a way to set breakpoints in the stored procedures such that when the call is made from C program ( using mySql client library ) into the stored proc , then control flow is halted in the C program and we can step into the stored proc called to whatever level of nesting and insspecting variables etc ( like any decent C debugged provides )? Is there ANY way to do the above ? Through some third party tool or the like if not through plain MySql . Help is appreciated. thanks

  • Is there a way to access the locale used by gettext under windows ?

    - by phtrivier
    I have a program where i18n is handled by gettext. The program works fine, however for some reason I need to know the name of the locale used by gettext at runtime (something like 'fr_FR') under win32. I looked into gettext sources, and there is a quite frightening function that computes it on all platforms (gl_locale_name, in a C file called "localename.h/c"). However, this file does not seem to be installed alongside gettext or libintl, so I can't seem to call the function. Is there another function provided by gettext to get this value ? Or in another package (boost, glib, anything ?) (On a related note, there is a thing called std::locale in the C++ standard library, and according to the doc calling std::locale("") should create a locale with the settings of the system, unless I am mistaken ... but then the name is 'C' under windows. Is it a viable way of getting the locale name ? What I am doing wrong ?)

  • Python, how to tell if screen is running.

    - by Joe Spoon
    Hello, I am very new to programming and am trying to run a python code to see if the screen program is running and if it is then to not run the rest of the code. This is what I have and it's not working. !/usr/bin/python import os var1 = os.system ('screen -r /root/screenlog/screen.log') fd = open("/root/screenlog/screen.log") content = fd.readline() while content: if content == "There is no screen to be resumed.": os.system ('/etc/init.d/tunnel.sh') print "The tunnel is now active." else: print "The tunnel is running." fd.close() I know there are probably several things here that don't need to be and quite a few that I'm missing. I will be running this program in cron. Thanks for any help.

  • Threading and pcap issues.

    - by cftmon
    I have a GUI program that allows a user a scan a network, the issue is that when the pcap_loop function is called, my GUI program becomes unresponsive.(the pcap_loop blocks the current thread). When i try to use pthreads, i got a SIGSEGV fault at the pcap_loop function.Why?It's as if the thread can't see the procPacket function itself. void procPacket(u_char *arg, const struct pcap_pkthdr *pkthdr, const u_char *packet) { //show packets here } void* pcapLooper(void* param) { pcap_t* handler = (pcap_t*) param; pcap_loop(handler, 900 ,procPacket, NULL ); } //some function that runs when a button is pressed //handler has been opened through pcap_open_live pthread_t scanner; int t = pthread_create(&scanner,NULL,&pcapLooper, &handler ); if(t) { std::cout << "failed" << std::endl; } pthread_join(scanner,NULL); //do other stuff.

  • static library vs dynamic libraries

    - by user295030
    Can someone please explain in easy terms what is static library linking vs dynamic library linking other one has a larger memory map than the other or that the static library is used to compile/link with the program that will use it versus being loaded at runtime? I also need to create a static library of a program that I made in vs2008 and give one function interface to access the library. one of the requirements reads as such " * API should be in the form of static library. company xxx will link the library into a third party application to prevent any possible exposure of the code(dll)" how can they say both static and dll at the same time. I have never works with static library before. So please any help would be nice.

  • Same code... but warning!Any ideas?

    - by FILIaS
    I've a question for a warning message that i get. For this line,using qsort: qsort(catalog, MAX ,sizeof catalog, struct_cmp_by_amount); I get this warning: warning: passing argument 4 of ‘qsort’ makes pointer from integer without a cast struct_cmp_by_amount is another function on the program. BUT,for another program with the same code, with the same exactly struct_cmp_by_amount function, i dont get that warning for the 4th argument! qsort(structs, structs_len, sizeof(struct st_ex), struct_cmp_by_price); I'm wandering about why that;s happening. Have you any idea?

  • New instruction sets in CPU

    - by Tomek Tarczynski
    Every new generation of CPU introduces some sets of new instruction, ie.: MMX,3DNOW,SSE and so on. I've got few general questions about them: 1) If some program uses for example SSE instruction can it be run on CPU that doesn't support SSE? 2) If yes , does it mean that those instuction will be changed to some greater number of simpler instuctions? 3) If not, does it mean that the real perfomance impact of such new instructions will be after few years when most CPU will support such technology (so there won't be any incompatibilities)? 4) When I compile a C++ program with optimizations does it mean that it'll use some of this new instructions? (I know that it depends on many factors, especcialy on the code, but I want some general answer) Or are they reserved mostly for programs written in asm?

  • While Loop Taking Alot of CPU Usage

    - by CuriousUser
    I am creating a keystroke logger for my personal interest, as well wanting to know how to capture and use them as functions (like key shortcuts). I got the code to learn how keylogger and GetAsyncKeyState() work: http://www.rohitab.com/discuss/index.php?showtopic=9931 I got it to run under Code::Blocks, but the weirdest things is that when I check my task manager, my CPU Usage rises to 100%. When I close the program, it goes back down, and goes back up to 100 when I turn it back on. I presume it's because of the infinite while loop, constantly checking for inputs, but I wanna know if there's anyway to decrease the CPU usage, without losing function. P.S How would I make a key shortcut? Like press (Ctrl + E) to make the program exit?

  • Xcode: How-to bind a key that triggers application to appear (background daemon)

    - by Shyam
    Hi, I am struggling to create a certain kind of application my Mac, using Xcode and Interface Builder (RubyCocoa). As I am a nuby (but understand some Ruby), I would like to know how I could let my interface appear only if a key is pushed (a toggle), while the program is running in the background. Similar behavior like when I'd press the F4-key to show Dashboard. Really neat would be if the program wouldn't be showing as running in the Dock, but as a funky icon in the top bar, like well "Growl". Thank you so much for your help, comments and feedback!

  • How to create an application which embeds and runs Python code without local Python installation?

    - by Robert
    Hello fellow software developers. I want to distribute a program which is scriptable by embedding the Python interpreter. What I don't want is that the user has to install Python first. So I'm looking for a solution where I distribute only the following components: my program executable and its libraries the Python library (dll/so) a ZIP-file containing all necessary Python modules and libraries. How can I accomplish this? Do you have a step-by-step recipe for me? The solution should be suitable for both Windows and Linux. Thanks in advance.
