  • Overlap of the variable in mysql, my column are set to my query result

    - by foodil
    The question is not clear , let me clarify it: try{ $sql = ' SELECT UserID <==== (***********Used here for query ******) FROM user WHERE Rights != ?'; $stmt = $conn->prepare($sql); $stmt->execute(array('admin')); $result= $stmt->fetchAll(); } catch(PDOException $e) { die ($e->getMessage().'<a href="add.php"> Back</a>'); } foreach ($result as $set) { if ($set['UserID']==$_SESSION['username']) $rights='edit'; else {$rights=$_POST[$set['UserID']];} if (($rights != 'default' || $set['UserID']==$_SESSION['username']) && $_POST['public']==0 ) { $user=$set['UserID']; try { $query="INSERT INTO user_list(UserID <==== (***********Used here for insert ******),ListID,UserRights) VALUES ($user,$lastID,$rights)"; $stmt = $conn->prepare($query); $stmt->execute(); } catch(PDOException $e) { die ($e->getMessage().'<a href="add.php"> Back</a>'); $conn->rollBack(); } } } As you can see the UserID is a query result but it is also the column i need to insert, so when i insert into the table it will casued an error SQLSTATE[42S22]: Column not found: 1054 Unknown column 'UserA_ID' in 'field list' because the column is modify by my query result from: $query="INSERT INTO user_list(UserID,ListID,UserRights) VALUES ($user,$lastID,$rights)"; to: $query="INSERT INTO user_list(query_result_id,ListID,UserRights) VALUES ($user,$lastID,$rights)"; How to fix it ?Thank you.

  • Why is my system freezing when I switch users

    - by ZeroDivide
    Hello I've recently upgraded from 13.04 to 13.10 64bit. I'm running AMD graphics with the proprietary drivers. I have two user accounts. Mine(administrator) and my girlfriend's(standard) My girlfriend clicks "switch user" from my lock screen and logs in fine. I then try to click "switch user" from her lock screen and everything goes black. Then the monitor blinks on and off with just a single cursor. I have no way to access the terminal, the system is unresponsive and I have to hit the power button. Even ctrl + alt + f4 or ctrl + alt + t doesn't get me a terminal. When I press the power button on my system, it does start printing out the shutdown sequence on the monitor. Here is my .xsession-errors Script for ibus started at run_im. Script for auto started at run_im. Script for default started at run_im. Here is hers: init: at-spi2-registryd main process ended, respawning init: at-spi2-registryd main process ended, respawning init: at-spi2-registryd main process ended, respawning init: at-spi2-registryd main process ended, respawning init: at-spi2-registryd main process ended, respawning init: at-spi2-registryd main process ended, respawning init: at-spi2-registryd main process ended, respawning init: at-spi2-registryd main process ended, respawning init: at-spi2-registryd main process ended, respawning init: at-spi2-registryd main process ended, respawning init: at-spi2-registryd respawning too fast, stopped init: logrotate main process (4726) killed by TERM signal init: upstart-dbus-session-bridge main process (4865) terminated with status 1 init: gnome-settings-daemon main process (4843) terminated with status 1 init: gnome-session main process (4852) terminated with status 1 init: unity-panel-service main process (4863) killed by KILL signal I found some advice in a forum to look for at-spi2-registryd in my system logs. Perhaps it will be useful. executing this: sudo grep -r at-spi2-registryd /var/log/* produces this: /var/log/lightdm/x-1-greeter.log:** (at-spi2-registryd:4384): WARNING **: Failed to register client: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files /var/log/lightdm/x-1-greeter.log:** (at-spi2-registryd:4384): WARNING **: Unable to register client with session manager /var/log/lightdm/x-2-greeter.log.old:** (at-spi2-registryd:7447): WARNING **: Failed to register client: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files /var/log/lightdm/x-2-greeter.log.old:** (at-spi2-registryd:7447): WARNING **: Unable to register client with session manager /var/log/lightdm/x-0-greeter.log:** (at-spi2-registryd:1378): WARNING **: Failed to register client: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files /var/log/lightdm/x-0-greeter.log:** (at-spi2-registryd:1378): WARNING **: Unable to register client with session manager /var/log/lightdm/x-0-greeter.log.old:** (at-spi2-registryd:1357): WARNING **: Failed to register client: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files /var/log/lightdm/x-0-greeter.log.old:** (at-spi2-registryd:1357): WARNING **: Unable to register client with session manager Any ideas what is going on?

  • wordpress woocommerce php variable usage %1$s

    - by tech
    I am using wordpress with woocommerce and I am trying to manipulate a copy of myaccount.php The default code uses some variables of some sort that I am not familiar with nor have I been able to find documentation on. The variables in question are %1$s, %2$s and %s <p class="myaccount_user"> <?php printf( __( 'Hello <strong>%1$s</strong> (not %1$s? <a href="%2$s">Sign out</a>).', 'woocommerce' ) . ' ', $current_user->display_name, wp_logout_url( get_permalink( wc_get_page_id( 'myaccount' ) ) ) ); ?> <?php printf( __( 'From this page you can view your recent orders, manage your shipping and billing addresses and <a href="%s">edit your password and account details</a>.', 'woocommerce' ), wc_customer_edit_account_url() ); ?> </p> How can I identify the variables, what they represent and how to use them? Thank you.

  • Creating a level editor event system

    - by Vaughan Hilts
    I'm designing a level editor for game, and I'm trying to create sort of an 'event' system so I can chain together things. If anyone has used RPG Maker, I'm trying to do similar to their system. Right now, I have an 'EventTemplate' class and a bunch of sub-classed 'EventNodes' which basically just contain properties of their data. Orginally, the IAction and IExecute interface performed logic but it was moved into a DLL to share between the two projects. Question: How can I abstract logic from data in this case? Is my model wrong? Isn't cast typing expensive to parse these actions all the time? Should I write a 'Processor' class to execute these all? But then these actions that can do all sorts of things need to interact with all sorts of sub-systems.

  • Creating a Template Like System in cPanel

    - by clifgray
    I am creating a medium sized website using cPanel and their File Manager system and the majority of my pages are going to be the same with a different title and content section and I wanted to see if there is a system for making one general template file and then having all the other pages inherit from that file so all I have to do is have a content and title section and the rest of the links, headers, and whatnot can be changed throughout the site by just changing one file. Is there anything like this? I have used Jinaj2 in python and a few other systems for other server scripting languages but I am not sure how to implement it with cPanel.

  • Linking one uniform variable to many shaders

    - by Winged
    Let's say, that I have 3 programs, and in each of those programs there is a view matrix uniform, which should be the same in all those programs. Right now, when my camera moves, I need to re-upload the modified matrix to every program separately. Is it possible to create some kind of global uniforms which are constant for all programs linked to it, so I could just upload the matrix once? I tried creating a globalUniforms object which looked kinda like this: var globalUniforms = { program: {}, // (...) vMatrixUniform: null, // (...) initialize: function() { vMatrixUniform = gl.getUniformLocation(this.program, 'uVMatrix'); } }; So I could just link it to proper programs like this: program.vMatrixUniform = globalUniforms.vMatrixUniform;, and then pass the matrix like this: if (camera.isDirty.viewMatrix !== false) { camera.isDirty.viewMatrix = false; gl.uniformMatrix4fv(globalUniforms.vMatrixUniform, false, camera.viewMatrix.element); } but unfortunately it throws an error: Uncaught exception: gl.INVALID_VALUE was caused by call to: getUniformLocation called from line 272, column 2 in () in mysite/js/mesh.js: vMatrixUniform = gl.getUniformLocation(this.program, 'uVMatrix'); Summing up: is there a more efficient way of managing shaders which follows my logic?

  • XNA 4.0 2D sidescroller variable terrain heightmap for walking/collision

    - by JiminyCricket
    I've been fooling around with moving on sloped tiles in XNA and it is semi-working but not completely satisfactory. I also have been thinking that having sets of predetermined slopes might not give me terrain that looks "organic" enough. There is also the problem of having to construct several different types of tile for each slope when they're chained together (only 45 degree tiles will chain perfectly as I understand it). I had thought of somehow scanning for connected chains of sloped tiles and treating it as a new large triangle, as I was having trouble with glitching at the edges where sloped tiles connect. But, this leads back to the problem of limiting the curvature of the terrain. So...what I'd like to do now is create a simple image or texture of the terrain of a level (or section of the level) and generate a simple heightmap (of the Y's for each X) for the terrain. The player's Y position would then just be updated based on their X position. Is there a simple way of doing this (or a better way of solving this problem)? The main problem I can see with this method is the case where there are areas above the ground that can be walked on. Maybe there is a way to just map all walkable ground areas? I've been looking at this helpful bit of code: http://thirdpartyninjas.com/blog/2010/07/28/sloped-platform-collision/ but need a way to generate the actual points/vectors.

  • How to play the sound of an object sliding on another object for a variable duration

    - by Antoine
    I would like to add sound effects to a basic 2D game. For example, a stone sphere is rolling on wood surface. Let's say I have a 2 second audio recording of this. How could I use the sample to add sound for an arbitrary duration ? So far I have two solutions in mind: a/ record the sound for an amount of time that is greater than the maximum expected duration, and play only a part of it; b/ extract a small portion of the sample and play it in a loop for the duration of the move; however I'm not sure if it makes sense with an audio wave.

  • 2D basic map system

    - by Cyril
    i'm currently coding a 2D game in Java, and I would like to have some clues on how-to build this system : the screen is moving on a grander map, for instance, the screen represent 800*600 units on a 100K*100K map. When you command your unit to go to another position, the screen move on this map AND when you move your mouse on a side or another of the screen, you move the screen on the map. Not sure that i'm clear, but we can retrieve this system in most RTS games (warcraft/starcraft for example). I'm currently using Slick 2D. Any idea ? Thanks.

  • Fixed Sized Buffer or Variable Buffers with C# Sockets

    - by Keagan Ladds
    I am busy designing a TCP Server class in C# that has events and allows the user of the class to define packets that the server can send a receive by registering a class that is derived from my "GenericPacket" class. My TCPListener uses Async methods such as .BeginReceive(..); My issue is that because I am using the .BeginReceive(); I need to specify a buffer size when I call the function. This means I cant read the whole packet if one of my defined packets is too big. I have thought of creating a fixed sized Header that gets read using .BeginRead(); and the read the rest using Stream.Read(); but this will lead to the whole server having to wait for this operation to complete. I would like to know if anyone has come across this before and I would appreciate any suggestions.

  • Render 3d object to 2d surface (embedded system)

    - by Martin Berger
    i am working on an embedded system of a sort, and in some free time i would like to test its drawing capabilities. System in question is ARM Cortex M3 microcontroller attached to EasyMX Stellaris board. And i have a small 320x240 TFT screen :) Now, i have some free time each day and i want to create rotating cube. Micro C PRO for ARM doesnt have 3d drawing capabilities, which means it must be done in software. From the book Introduction to 3D Game Programming with DirectX 10 i know matrix algebra for transformations but that is cool when you have DirectX to set camera right. I gues i could make 2d object to rotate, but how would i go with 3d one? Any ideas and examples are welcome. Although i would prefer advices. I'd like to understand this.

  • 1 to 1 Comparison and Ranking System

    - by David
    I'm looking to create a comparison and ranking system which allows users to view 2 items, click on the one that they feel is the better one and then get presented with 2 more random items and continue to do this until they decide to stop. In the background, I want the system to use these wins and loses to rank each item in an overall ranking table so I can then see what is #1 and what isn't. I haven't got a clue where to begin with the formula, but I image I need to log wins and loses. Any help/direction appreciated!

  • Plan variable and call dependencies

    - by Gerenuk
    I'd like to write down the design of my program to understand the dependencies and calls better. I know there are class diagrams which show inheritance and attribute variables. However I'd also like to document the input parameters to method functions and in particular which calls the methods function executes inside (e.g. on the input parameters). Also sometimes it might be useful to show how actual objects are connected (if there is a standard structure). This way I can have a better understanding of the modules and design before starting to program. Can you suggest a method to do this software design? It should be one-to-one to programming code structure so that I really notice all quirks beforehand (instead of high-level design where thing are hard to implement without further work). Maybe some special diagram or tool or a combination? It is static dependency and call design rather than time dependent execution monitoring. (I use Python if you have any specialized recommendations).

  • Orthographic Projection with variable FOV

    - by cubrman
    We are building agame with orthographic view. The problem we face is the fact that with different resolution you can see different area of the game world. E.g. if you have higher resolution you can see more around you. To solve this we currently use a common scale factor that every model is scaled by, depending on resolution. But this has drawbacks when drawing shadows - I cannot set a higher view angle for the orthographic shadow camera, while when using the perspective shadow camera I get significantly worse shadow quality. So the question is is there any way to controll FOV when using orthographic projection, or, more specifically, what is the easiest way to scale the world uniformly up or down with orthographic projection matrix? I saw that in 3ds MAX you can control FOV for an orthographic camera I wonder how they implemented it.

  • How to convert an XFS file system to HFS+

    - by user219350
    I have repeatedly convinced of the reliability of the XFS file system , and I was more than satisfied . I was happy with everything in Ubuntu 14.04 ( great software) , but there is a little "but ! " Basically, I work on OSX-Mavericks 10.9.3, which sees very Windows 8.1 and works wonders with NTFS, but does not see Ubuntu! Briefly describe the equipment: ASRock B75 Pro3-M i5 3330 GeForce GTX 650 Ti SATA 500GB running OS X Mavericks + Clover - a boot disk Toshiba 2TB running Windows 8.1 (x64) and Ubuntu 14.04 (amd64) If you boot from the Toshiba (where there is Ubuntu and boot Windows + GRUB) after restart boot from Clover, it is impossible. Tried a lot of options - as Clover installation and boot priority, and various settings for GRUB, but have not found an acceptable option and have no desire to reinstall again Clover (Mavericks reboots 20 seconds - excellent!) So please help on the file system - how to convert from XFS to HFS+ journaled. Mavericks to saw it all synced on Mac. Thank you for the sensible answer and help! Originally in Russian.

  • I need help installing Ubuntu 11.10 to multi-drive system

    - by CookyMonzta
    I have a machine with 3 hard drives; the primary, which is 750GB (drive 0), and 2 others, each of which is 640GB (drives 1 and 2). On the last screen before the actual installation begins, this is how my hard drive configuration looks: /dev/sda [DISK0, 750GB] /dev/sda1 ntfs 104MB [Win7 System Reserved] /dev/sda2 ntfs 499,997MB [Windows 7 Pro] free space 250,052MB [This space intended for Windows 8] /dev/sdb [DISK1, 640GB] /dev/sdb1 ntfs 400,085MB [Windows XP Pro] free space 240,049MB [This space intended for Ubuntu] /dev/sdc [DISK2, 640GB] [This drive intended for various backups] free space 160,033MB /dev/sdc5 ntfs 480,101MB [Acronis Secure Zone] As you can see, I have 3 drives, all SATA. I have Win7 on my first drive (0), WinXP on my second drive (1) and a secure zone for daily backups on my third drive (2). I want to put Ubuntu 11.10 Oneiric Ocelot on the drive that also has XP. I've already used 400GB for XP and I have 240GB remaining, for which, my intention was to create a 4GB swap file and use the rest for Ubuntu itself. This is what my second hard drive looked like, for my intended setup before installation: /dev/sdb /dev/sdb5 swap 4,095MB [Linux swap] /dev/sdb6 ext4 235,951MB [Ubuntu 11.10] Needless to say, this is only the second time I have attempted to install Linux. I managed to get 7.10 Gutsy Gibbon working on an old machine. I have two problems with this installation: Ubuntu asks for a location to install the boot loader (i.e., "Device for Boot Loader Installation"). I already have a boot loader; namely, Acronis OS Selector (from Acronis Disk Director 11). So I decided to put the Ubuntu boot loader in /dev/sdb6 (where I intend to install Ubuntu), to keep it from interfering with my Acronis OS Selector. Once I hit "Install now", I ended up with the following error: "No root file system is defined. Please correct this from the partitioning menu." What am I missing? Did I attempt to put the boot loader in the wrong place? I assume I did, because as I am writing this entry, I am looking at LinuxIdentity.com's Ubuntu 11.04 Natty Narwhal magazine, and I see a screenshot (Figure 7 on Page 13) that implies that the boot loader can be installed anywhere, including the first hard drive (in the MBR, which would obviously force me to reinstall the Acronis OS Selector) or even on a floppy. But why do I get an undefined root file system error? I thought /dev/sdb6 was the root file. Obviously I'm missing something in the installation procedure. Should I try installing it in Windows using the WUBI Installer? I assume that, if I attempt to install Ubuntu from WinXP (on the second drive), it will automatically install Ubuntu on the empty partition alongside XP. But will I have the option of creating a swap partition? And what if the WUBI Installer searches all of my drives and decides to install Ubuntu on my first drive's empty partition (which I have left empty for Win8 upon its release)?

  • Clear Linux file system after shutdown / start

    - by user35443
    I have very specific task. I need to clear the desktop, downloads, documents and so on after every shutdown or finish. For example, if anyone downloads something using Google Chrome, he will work with it and then he'll shutdown the computer for next use. And when second user sits for working on the computer, he'll find a clear file system without the data downloaded by the first user. On Windows, I used to work with Returnil Virtual System, but it doesn't have support for Linux. Can anybody tell me if is it possible and, if so, how? I was also thinking of using Wine for this program, but don't think it will be the best idea.

  • Calculating WPM given a variable stream of input

    - by Jaxo
    I'm creating an application that sits in the background and records all key presses (currently this is done and working; an event is fired every keydown/keyup). I want to offer a feature for the user that will show them their WPM over the entire session the program has been running for. This would be easy if I added a "Start" and "End" button to activate a timer, but I need to detect only when the user is typing continuously - ignoring all one-time keyboard shortcuts and breaks the user takes from typing. How in the world do I approach this? Is this even realistically & accurately possible?

  • plotting histograms in ROOT with varying variable names

    I am not sure how to phrase this question correctly, but this is what I am trying to do. A single histogram can be plotted using cern ROOT with a following command, (TH1F*)electron->Draw(); But I have tens of histograms named in a sequence, such as electron1, elecron2, electron3, etc, and I want to write a simple loop to plot them all. I tried using sprintf and a simple for loop, but ROOT doesn't like it. char name[20]; (TH1F*)electron->Draw(); for(int j=0;j<5;j++){ sprintf(name, "%s%d","electron",j); (TH1F*)name->Draw("same"); } What am I doing wrong? Thanks in advance.

  • Guide to installing a fully encrypted file system?

    - by Michael Stum
    I have a little Netbook on which I want to install Ubuntu 10.10 (32-Bit) on. However, since it is a portable PC I want to completely encrypt the file system (in case of theft). Currently it runs Windows 7 Starter and I use TrueCrypt which installs a custom boot loader that asks for the password. I remember from the past that Linux can do that as well by putting /boot on it's own, unencrypted partition. Since it's been ages since I last worked with file system encryption (I remember setting up LVM and a custom patched grub to ask for the password) I wonder how that would work nowadays and if there is a step-by-step how-to for it?
