  • Need help INSERT record(s) MySQL DB

    - by JM4
    I have an online form which collects member(s) information and stores it into a very long MySQL database. We allow up to 16 members to enroll at a single time and originally structured the DB to allow such. For example: If 1 Member enrolls, his personal information (first name, last name, address, phone, email) are stored on a single row. If 15 Members enroll (all at once), their personal information are stored in the same single row. The row has information housing columns for all 'possible' inputs. I am trying to consolidate this code and having every nth member that enrolls put onto a new record within the database. I have seen sugestions before for inserting multiple records as such: INSERT INTO tablename VALUES (('$f1name', '$f1address', '$f1phone'), ('$f2name', '$f2address', '$f2phone')... The issue with this is two fold: I do not know how many records are being enrolled from person to person so the only way to make the statement above is to use a loop The information collected from the forms is NOT a single array so I can't loop through one array and have it parse out. My information is collected as individual input fields like such: Member1FirstName, Member1LastName, Member1Phone, Member2Firstname, Member2LastName, Member2Phone... and so on Is it possible to store information in separate rows WITHOUT using a loop (and therefore having to go back and completely restructure my form field names and such (which can't happen due to the way the validation rules are built.)

  • 'For' Loop Within a 'For' Loop and Then Another?

    - by BenjaminFranklin
    This has confused me quite a bit, but it's also really interesting! I want to loop through a grid of 9 elements in an array, multiply them all by 1/9. Then, I want to find the sum of those 9 elements and replace each individual element's with the value calculated as the sum. After I've done this, I want to move on to the next nine elements. To clarify, I want all 9 elements to be changed to myVal, in the code below. So far I've got the loop within a loop bit, but I don't know how to then go back and replace each of the values with the sum of all of them combined. Here's my code:- previousx = 0; previousy= 0; for (int x = previousx; x < previousx+4; x++) { for(int y = previousy; y < previousy+4; y++) { y = y*(1/9); yVal += y; } } Any advice would, of course, be greatly appreciated.

  • Calculations coming out to 0.0?

    - by Nick Gibson
    A simple percentage calculation. It wont return a value except 0.0 and I think once or twice it returned 100.0%. Other than that it won't do a thing. I have tried playing with the code in several different ways and it just wont work. for (int loop = 1; loop < loopCount; loop++) { aa = r.nextInt(10+1); abc = (int) aa; String[] userAnswer = new String[x]; int totalQues = (correctAnswer + wrongAnswer), actualQues = (totalQues - 1); if(abc < x) { userAnswer[abc] = JOptionPane.showInputDialog(null,"Question "+quesNum+"\n\n"+questions[abc]+"\n\nA: "+a[abc]+"\nB: "+b[abc]+"\nC: "+c[abc]+"\nD: "+d[abc]+"\nCorrect Answers: "+correctAnswer+"\nWrong Answers: "+wrongAnswer+"\nTotal Questions: "+totalQues); if(userAnswer[abc].equals(answers[abc])) { correctAnswer++; } else { wrongAnswer++; }//else if(actualQues == x); { score = (correctAnswer / actualQues) * 100; JOptionPane.showMessageDialog(null,"The test is finished."); JOptionPane.showMessageDialog(null,"You scored "+score+"%"); }//if }//if }//for

  • run two thread at the same time in java

    i have used timertask to schedule my java program. now when the run method of timertask is in process, i want to run two threads which run at the same time and do different functions. here is my code.. please help me.. import java.util.Calendar; import java.util.Date; import java.util.Timer; import java.util.TimerTask; public class timercheck extends TimerTask{ // my first thread Thread t1 = new Thread(){ public void run(){ for(int i = 1;i <= 10;i++) { System.out.println(i); } } }; // my second thread Thread t2 = new Thread(){ public void run(){ for(int i = 11;i <= 20;i++) { System.out.println(i); } } }; public static void main(String[] args){ long ONCE_PER_DAY = 1000*60*60*24; Calendar calendar = Calendar.getInstance(); calendar.set(Calendar.HOUR_OF_DAY, 12); calendar.set(Calendar.MINUTE, 05); calendar.set(Calendar.SECOND, 00); Date time = calendar.getTime(); TimerTask check = new timercheck(); Timer timer = new Timer(); timer.scheduleAtFixedRate(check, time ,ONCE_PER_DAY); } @Override // run method of timer task public void run() { t1.start(); t2.start(); } }

  • Why doesn't this for loop work?

    - by evilsoup
    This is on Ubuntu 12.04 I'm trying to figure out how to get ffmpeg to do a batch conversion of FLACs to MP3, recursively. If I cd into a directory and use for f in *.flac; do ffmpeg -i "$f" -c:a libmp3lame -q:a 2 "${f/%flac/mp3}"; done that works perfectly fine. However, when I try this, it doesn't work: for f in "$(find . -type f -name *.flac)"; do ffmpeg -i "$f" -c:a libmp3lame -q:a 2 "${f/%flac/mp3}"; done It doesn't even throw up any useful errors (but here is the output anyway, no need to complain): evilsoup@enchantment:~/Music/Jean Sibelius$ for f in "$(find . -type f -name *.flac)"; do ffmpeg -i "$f" -c:a libmp3lame -q:a 2 "${f/%flac/mp3}"; done ffmpeg version git-2012-12-18-b7e085a Copyright (c) 2000-2012 the FFmpeg developers built on Dec 18 2012 19:23:11 with gcc 4.6 (Ubuntu/Linaro 4.6.3-1ubuntu5) configuration: --enable-gpl --enable-libfaac --enable-libfdk-aac --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-librtmp --enable-libtheora --enable-libvorbis --enable-libvpx --enable-x11grab --enable-libx264 --enable-nonfree --enable-version3 libavutil 52. 12.100 / 52. 12.100 libavcodec 54. 80.100 / 54. 80.100 libavformat 54. 49.102 / 54. 49.102 libavdevice 54. 3.102 / 54. 3.102 libavfilter 3. 28.100 / 3. 28.100 libswscale 2. 1.103 / 2. 1.103 libswresample 0. 17.102 / 0. 17.102 libpostproc 52. 2.100 / 52. 2.100 ./Symphonies 1, 2, 3 & 5 (Oslo Philharmonic Orchestra Conducted by Mariss Jansons) Disc 1/02.

  • Why does my game loop speed vary on different platforms with the same hardware?

    - by Sri Harsha Chilakapati
    I've got a serious issue with my game loop. This loop varies in time with the platform and with the same hardware. This is a list of FPS achieved: - Windows ======= 140 to 150 - Linux ======= 120 to 125 - Windows(WINE) ======= 125 to 135 And since my game loop is fixed timestep, the speed of the game is not stable. Here's my game loop. public final void run() { // Initialize the resources Map.initMap(); initResources(); // Start the timer GTimer.startTimer(); GTimer.refresh(); long elapsedTime = 0; // The game loop while (running) { // Update the game update(elapsedTime); if (state == GameState.GAME_PLAYING) { Map.updateObjects(elapsedTime); } // Show or hide the cursor if (Global.HIDE_CURSOR) { setCursor(GInput.INVISIBLE_CURSOR); } else { setCursor(Cursor.getDefaultCursor()); } // Repaint the game and sync repaint(); elapsedTime = GTimer.sync(); Toolkit.getDefaultToolkit().sync(); } } The timer package How could I improve it?

  • What are the pros and cons of a non-fixed-interval update loop?

    - by akonsu
    I am studying various approaches to implementing a game loop and I have found this article. In the article the author implements a loop which, if the processing falls behind in time, skips frame renderings and just updates the game in a loop (the last variant called "Constant Game Speed independent of Variable FPS"). I do not understand why it is acceptable to call update_game() in a loop without making sure the update function is called at a particular interval. I do not see any value in doing this. I would think that in my game I want to be sure the game is updated periodically with a known period. So maybe it is worthwhile to have two threads, one would call update periodically, and the other one would redraw the game, also periodically? Would this be a good and practical approach? Of course I would need to synchronise the threads.

  • VBA nested Loop flow control

    - by PCGIZMO
    I will be brief and stick to what I know. This code for the most part works as it should. The only issue is in the iteration of the x and z loop. these to loops should set the range and yLABEL for the Y loop. I can get through a set and come up with the correct range after that things go bonkers. I know some of it has to do with not breaking out of x to set z and then back to x update the range. It should work z is found then x. the range between them is set for y. then next x but y stays then rang between y and x is set for y.. so on and so forth kinda like a slinky down the stairs. or a slide rule depending on how I set the loops either way I end up all over the place after a couple iterations. I have done a few things but each time I break out of x to set z , X restarts at the top of the range. At least that's what I think I am seeing. In the example sheet i have since changed the way the way the offset works with the loop but the idea is still the same. I have goto statements at this time i was going to try figuring out conditional switches after the loops were working. Any help direction or advice is appreciated.

  • Lockless queue implementation ends up having a loop under stress

    - by Fozi
    I have lockless queues written in C in form of a linked list that contains requests from several threads posted to and handled in a single thread. After a few hours of stress I end up having the last request's next pointer pointing to itself, which creates an endless loop and locks up the handling thread. The application runs (and fails) on both Linux and Windows. I'm debugging on Windows, where my COMPARE_EXCHANGE_PTR maps to InterlockedCompareExchangePointer. This is the code that pushes a request to the head of the list, and is called from several threads: void push_request(struct request * volatile * root, struct request * request) { assert(request); do { request->next = *root; } while(COMPARE_EXCHANGE_PTR(root, request, request->next) != request->next); } This is the code that gets a request from the end of the list, and is only called by a single thread that is handling them: struct request * pop_request(struct request * volatile * root) { struct request * volatile * p; struct request * request; do { p = root; while(*p && (*p)->next) p = &(*p)->next; // <- loops here request = *p; } while(COMPARE_EXCHANGE_PTR(p, NULL, request) != request); assert(request->next == NULL); return request; } Note that I'm not using a tail pointer because I wanted to avoid the complication of having to deal with the tail pointer in push_request. However I suspect that the problem might be in the way I find the end of the list. There are several places that push a request into the queue, but they all look generaly like this: // device->requests is defined as struct request * volatile requests; struct request * request = malloc(sizeof(struct request)); if(request) { // fill out request fields push_request(&device->requests, request); sem_post(device->request_sem); } The code that handles the request is doing more than that, but in essence does this in a loop: if(sem_wait_timeout(device->request_sem, timeout) == sem_success) { struct request * request = pop_request(&device->requests); // handle request free(request); } I also just added a function that is checking the list for duplicates before and after each operation, but I'm afraid that this check will change the timing so that I will never encounter the point where it fails. (I'm waiting for it to break as I'm writing this.) When I break the hanging program the handler thread loops in pop_request at the marked position. I have a valid list of one or more requests and the last one's next pointer points to itself. The request queues are usually short, I've never seen more then 10, and only 1 and 3 the two times I could take a look at this failure in the debugger. I thought this through as much as I could and I came to the conclusion that I should never be able to end up with a loop in my list unless I push the same request twice. I'm quite sure that this never happens. I'm also fairly sure (although not completely) that it's not the ABA problem. I know that I might pop more than one request at the same time, but I believe this is irrelevant here, and I've never seen it happening. (I'll fix this as well) I thought long and hard about how I can break my function, but I don't see a way to end up with a loop. So the question is: Can someone see a way how this can break? Can someone prove that this can not? Eventually I will solve this (maybe by using a tail pointer or some other solution - locking would be a problem because the threads that post should not be locked, I do have a RW lock at hand though) but I would like to make sure that changing the list actually solves my problem (as opposed to makes it just less likely because of different timing).

  • Weird vps server issue

    - by anon-user0
    I have an unmanaged linux vps Ubuntu 11.10 (Oneiric Ocelot). I have LNMP installed. Also php-fpm php-apc, varnish, memcache. I have (or rather had) several live sites on it. under normal load the server uses ~700 mb memory. But since last night its using only 20mb~ memory and a lot of the services seems to be down (according to htop) I only see nginx working and mysql starts up and goes does every few minutes on a loop. Here are some information on the server that might help you help me: root@server:~# uname -a Linux server 2.6.18-308.el5.028stab099.3 #1 SMP Wed Mar 7 15:56:00 MSK 2012 i686 i686 i386 GNU/Linux - root@server:~# ifconfig -a lo Link encap:Local Loopback LOOPBACK MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) venet0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:127.0.0.2 P-t-P:127.0.0.2 Bcast:0.0.0.0 Mask:255.255.255.255 UP BROADCAST POINTOPOINT RUNNING NOARP MTU:1500 Metric:1 RX packets:12515 errors:0 dropped:0 overruns:0 frame:0 TX packets:9541 errors:0 dropped:1 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:7191214 (7.1 MB) TX bytes:536726 (536.7 KB) venet0:0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:176.31.158.78 P-t-P:176.31.158.78 Bcast:0.0.0.0 Mask:255.255.255.255 UP BROADCAST POINTOPOINT RUNNING NOARP MTU:1500 Metric:1 - root@server:~# netstat -l Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 *:http-alt *:* LISTEN tcp 0 0 *:ssh *:* LISTEN tcp6 0 0 [::]:http-alt [::]:* LISTEN tcp6 0 0 [::]:ssh [::]:* LISTEN Active UNIX domain sockets (only servers) Proto RefCnt Flags Type State I-Node Path unix 2 [ ACC ] STREAM LISTENING 9307368 @/com/ubuntu/upstart - htop: http://i.stack.imgur.com/NHKYX.png EDIT: Stressed. mind was not working adding log: root@server:~# less /var/log/syslog Jun 27 05:27:42 server syslogd 1.5.0#6ubuntu1: restart.

  • Use the Twitter API to run a script every time I post a new tweet

    - by Mathias Bynens
    I have a PHP script on my server that I want to run every time I post a new tweet to Twitter. Is there a way to automate this? I could of course set up a cron job to run the script every five minutes, or run the script manually every time after tweeting, but neither of those is instant — and that’s exactly what I’m looking for. Is it possible to use the Twitter API to run a script / get a URL every time my timeline is updated?

  • PHPUnit won't run tests by directory

    - by Frank Schwieterman
    I'm new to PHP, trying to get multiple tests to run at once. I was hoping to just run all tests in a directory, which seemed to work awhile (instead of using a phpunit.xml). I am able to run a test individually like so: phpunit FirstUnitTest sites\all\modules\experiment\unit-tests\FirstUnitTest.lua But when I try to run the same test by directory, its not found. I try using: phpunit sites\all\modules\experiment\unit-tests Does anyone know why this may not work?

  • SBT run differences between scala and java?

    - by Eric Cartner
    I'm trying to follow the log4j2 configuration tutorials in a SBT 0.12.1 project. Here is my build.sbt: name := "Logging Test" version := "0.0" scalaVersion := "2.9.2" libraryDependencies ++= Seq( "org.apache.logging.log4j" % "log4j-api" % "2.0-beta3", "org.apache.logging.log4j" % "log4j-core" % "2.0-beta3" ) When I run the main() defined in src/main/scala/logtest/Foo.scala: package logtest import org.apache.logging.log4j.{Logger, LogManager} object Foo { private val logger = LogManager.getLogger(getClass()) def main(args: Array[String]) { logger.trace("Entering application.") val bar = new Bar() if (!bar.doIt()) logger.error("Didn't do it.") logger.trace("Exiting application.") } } I get the output I was expecting given that src/main/resources/log4j2.xml sets the root logging level to trace: [info] Running logtest.Foo 08:39:55.627 [run-main] TRACE logtest.Foo$ - Entering application. 08:39:55.630 [run-main] TRACE logtest.Bar - entry 08:39:55.630 [run-main] ERROR logtest.Bar - Did it again! 08:39:55.630 [run-main] TRACE logtest.Bar - exit with (false) 08:39:55.630 [run-main] ERROR logtest.Foo$ - Didn't do it. 08:39:55.630 [run-main] TRACE logtest.Foo$ - Exiting application. However, when I run the main() defined in src/main/java/logtest/LoggerTest.java: package logtest; import org.apache.logging.log4j.Logger; import org.apache.logging.log4j.LogManager; public class LoggerTest { private static Logger logger = LogManager.getLogger(LoggerTest.class.getName()); public static void main(String[] args) { logger.trace("Entering application."); Bar bar = new Bar(); if (!bar.doIt()) logger.error("Didn't do it."); logger.trace("Exiting application."); } } I get the output: [info] Running logtest.LoggerTest ERROR StatusLogger Unable to locate a logging implementation, using SimpleLogger ERROR Bar Did it again! ERROR LoggerTest Didn't do it. From what I can tell, ERROR StatusLogger Unable to ... is usually a sign that log4j-core is not on my classpath. The lack of TRACE messages seems to indicate that my log4j2.xml settings aren't on the classpath either. Why should there be any difference in classpath if I'm running Foo.main versus LoggerTest.main? Or is there something else causing this behavior? Update I used SBT Assembly to build a fat jar of this project and specified logtest.LoggerTest to be the main class. Running it from the command line produced correct results: Eric-Cartners-iMac:target ecartner$ java -jar "Logging Test-assembly-0.0.jar" 10:52:23.220 [main] TRACE logtest.LoggerTest - Entering application. 10:52:23.221 [main] TRACE logtest.Bar - entry 10:52:23.221 [main] ERROR logtest.Bar - Did it again! 10:52:23.221 [main] TRACE logtest.Bar - exit with (false) 10:52:23.221 [main] ERROR logtest.LoggerTest - Didn't do it. 10:52:23.221 [main] TRACE logtest.LoggerTest - Exiting application.

  • QLogic QLE8152 won't link up with a fiber loop

    - by Mike Pennington
    I have a Dell R710 running Debian Linux 6.0 (Squeeze). I installed a QLogic QLE8152 CNA in the PCI-E riser today and I have been trying to get the CNA's ethernet layer to come up after I put a fiber loop on it; I also scoped it with a light meter, and the SFP+ transceiver is getting the correct amount of light. The whole time I have been working on this problem, the lights on the CNA are blinking green at a rate of about 1 flash every 3 seconds. When I plug the fiber into a Juniper EX4500 10GE in a rack next to it, the Juniper's link stays down as well. I have to confess that this is my first wrangling with a CNA, so perhaps I'm doing something fundamentally wrong, but here is what I have found so far... First the basics...

  • Run a perl script as a windows 7 service

    - by reptile
    I have a perl script which is compiled using pp, to be run as a windows service on windows 7 machines. I looked at the thread http://www.perlmonks.org/index.pl?node%5Fid=230377 but of little use because most of them weren't clear and the solutions suggested in that were to create executables and not actually for running as a windows 7 service. I tried putting my compiled exe in the scheduled tasks of windows but I think its not able to run for some reason. How do I debug this?

    - by Shahryar G. Hashemi
    Hi, We have a Windows 2008 cluster with several SQL 2008 instance. We would like to run a script that modifies 4 registry keys prior to the startup of SQL. I do not know if there is a way to have a script run through Windows 2008 clustering that does that. I have a VBS script to do it and tried to add a Generic Script to an existing cluster group, but it failed saying it could not be registered. Any ideas?

Try installing the program again using the original installation media or contact your system administrator or the software vendor for support I've uninstalled and reinstalled the application but it just won't work. Any clues/suggestions? Office 2010 which i installed prior is working fine.

  • Adding to App Paths for 'Run' as a non-admin

    - by Cooper
    Is there a way to add a new App Path (for adding commands to Start-Run) without needing Admin? With admin, you can add an App Path to HKLM\Software\Microsoft\Windows\CurrentVersion\App Paths. I tried adding one under HKCU with no effect. I've added a new (user-writable) location to my user's PATH environment variable which lets me launch things from Start-Run, but the nerd in me still wants to know about the App Paths.
