  • javascript/jquery input fields cleanup

    - by user271619
    I've created a few input fields, that I am cleaning up as the user types. So, I'm using a keystroke detection event, like .keyup() It's all working very well, but I do notice one thing that's rather annoying for the users. While the script is cleaning the data as they type, their cursor is being sent to the end of the input field. So, if you want to edit the middle of the value, you're cursor immediately goes to the end of the box. Does anyone know of a way to maintain the cursor's current position inside the input field? I'm not holding my breath, but I thought I'd ask. Here's the cleanup code I'm using: $(".pricing").keyup(function(){ // clean up anything non-numeric **var itemprice = $("#itemprice").val().replace(/[^0-9\.]+/g, '');** // return the cleaner value back to the input field **$("#itemprice").val(itemprice);** });

  • How to send a signal SIGINT from script to script ? BASH

    - by debugger
    I want to trap a signal send from Script-A.sh to Script-B.sh so in Script-A.sh i use the command (Send SIGINT to Script-B.sh) kill -2 $PID_Script-B.sh And in Script-B.sh i catch the signal and call function Clean trap 'Clean' 2 It does not work, instead the Script-B.sh is killed right away without performing the Clean !! What i notice also is that if i want to send SIGINT from terminal to any script that traps it, a ctrl-c will be catched correctly, but not if i specify the signal via the command kill -2 $pid_of_script Any idea about the difference between the two method to send the SIGINT (ctrl-c VS kill -2 $pid_of_script), and how i can send a SIGINT from a script to another ? Regards, Debugger

  • AudioQueueOfflineRender returning empty data

    - by hyn
    I'm having problems using AudioQueueOfflineRender to decode AAC data. When I examine the buffer after the call, it is always filled with empty data. I made sure the input buffer is valid and packet descriptions are provided. I searched and found that a few others have had the same problem: http://lists.apple.com/archives/Coreaudio-api/2008/Jul/msg00119.html Also, the inTimestamp argument doesn't make sense to me. Why should the renderer care where in the audio the beginning of the buffer corresponds to? The function throws an error if I pass in NULL, so I pass in the timestamp anyway.

  • Java replace slow?

    - by cpf
    Hi StackOverflow, I have a Java application that makes heavy use of a large file, to read, process and give through to SolrEmbeddedServer (http://lucene.apache.org/solr/). One of the functions does basic HTML escaping: private String htmlEscape(String input) { return input.replace("&", "&amp;").replace(">", "&gt;").replace("<", "&lt;") .replace("'", "&apos;").replaceAll("\"", "&quot;"); } While profiling the application, the program spends roughly 58% of the time in this function, a total of 47% in replace, and 11% in replaceAll. Now, is the Java replace that slow, or am I on the right path and should I consider the program efficient enough to have its bottleneck in Java and not in my code? (Or am I replacing wrong?) Thanks in advance!

  • AS3: Weak Listener References Not Appropriate During Initialization?

    - by TheDarkIn1978
    as i currently understand, if an event listener is added to an object with useWeakReference set to true, then it is eligible for garbage collection and will be removed if and when the garbage collection does a sweep. public function myCustomSpriteClass() //constructor { this.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownListener, false, 0, true); this.addEventListener(MouseEvent.MOUSE_UP, mouseUpListener, false, 0, true); } in this case, is it not appropriate to initialize an object with weak references event listeners, incase the garbage collector does activate a sweep removing the objects event listeners since they were added during initialization of the object? in this case, would it only be appropriate to create a type of deallocate() method which removes the event listeners before the object is nullified?

  • changing Python code in the debugger

    - by max
    Is there any debugger that allows Python code to be changed while debugging? In other words: run-time exception occurs, debugger stops, I change the code any way I like, and tell the program to continue. I am aware of the problems with this approach, such that references to functions would still point to the old definitions if I redefine the function on the fly, and so on. I am ok with that, since I just want to be able to make small fixes in very simple circumstances. On the other hand, I'm also interested in whether it's theoretically possible to allow changes to Python code without running into these problems: i.e., somehow update all the references to the objects that changed, etc. I'm nearly sure the answer to the second question is no, but if I'm wrong, I'd like to know. EDIT: If my goal (changing the code interactively when an exception occurred, and then continuing execution), is achievable without a debugger - that would be good as well. I don't need to use the debugger.

  • Perl equivalent to Java's "throws" clause

    - by Konerak
    Is there a way in Perl to declare that a method can throw an error (or die)? EDIT: What interests me the most is a way to get the compiler or IDE to tell me I have an unchecked exception somewhere in my code. I always loved how in Java, a method could handle an Exception and/or throw it. The method signature allows to put "throws MyException", so a good IDE/compiler would know that if you use said method somewhere in your code, you'd have to check for the Exception or declare your function to "throws" the Exception further. I'm unable to find something alike in Perl. A collegue of mine wrote a method which "dies" on incorrect input, but I forget to eval-if($@) it... offcourse the error was only discovered while a user was running the application. (offcourse I doubt if there is any existing IDE that could find these kind of things for Perl, but atleast perl -cw should be able to, no?)

  • Aborting jQuery().load()

    - by Daniel I-S
    The .load() function of the jQuery library allows you to selectively load elements from another page (subject to certain rules). I would like to know whether it is possible to abort the load process. In our application, a user can browse a list of items. They may choose to click a button which loads and displays additional information about an item from another document (which can take some time). If they choose a different item in the list whilst a .load() is still happening, I would like the loading to be aborted. Is this possible? Is it even worth it? Any ideas? Dan

  • Issue reading packets from a pcap file. dpkt module. What gives?

    - by Chris
    I am running the following test script to try to read packets from a sample .pcap file I have downloaded. It won't seem to run. I have all of the modules, but no examples seem to be running. import socket import dpkt import sys pcapReader = dpkt.pcap.Reader(file("test1.pcap", "rb")) for ts, data in pcapReader: ether = dpkt.ethernet.Ethernet(data) if ether.type != dpkt.ethernet.ETH_TYPE_IP: raise ip = ether.data src = socket.inet_ntoa(ip.src) dst = socket.inet_ntoa(ip.dst) print "%s -> %s" % (src, dst) For some reason, this is not being interpreted properly. When running it, I get KeyError: 138 module body in test.py at line 4 function __init__ in pcap.py at line 105 Program exited. Why is this? What's wrong?

  • PostGIS - can't create spatially-enabled database

    - by itgorilla
    I'm using Ubuntu 10.10, PostgreSQL 9.0 and PostGIS 1.5. I've installed PostGIS 1.5 from: https://launchpad.net/~ubuntugis/+archive/ubuntugis-unstable I used PPA first then the command: sudo apt-get install postgis to install postgis. I've been following these instructions to create a spatially-enabled database: http://ostgis.refractions.net/docs/ch02.html#id2630100 I got to the point where it's saying: Now load the PostGIS object and function definitions into your database by loading the postgis.sql definitions file (located in [prefix]/share/contrib as specified during the configuration step). psql -d [yourdatabase] -f postgis.sql Well, there is no postgis.sql on my server after the installation. I did an sudo updatedb to make sure I can find postgis.sql but it's not there. Any ideas? Thank you!

  • Passing methods/functions as args in Objective C

    - by Baishampayan Ghose
    Hello, I am new to Objective C and I am trying to implement an async library which works with callbacks. I need to figure out a way to pass callback methods as args to my async methods so that the callback can be invoked when the task is finished. What is the best way to achieve this in Objective C? In Python, for example I could easily pass a function, but in Objective C it seems selectors are the way to go(?). Can anyone point me to an example from where I can get some ideas? Thanks in advance.

  • Odd compiler error on if-clause without braces

    - by DisgruntledGoat
    The following Java code is throwing a compiler error: if ( checkGameTitle(currGame) ) ArrayList<String> items = parseColumns( tRows.get(rowOffset+1), currGame, time, method ); checkGameTitle is a public static function, returning a boolean. The errors are all of the type "cannot find symbol" with the symbols being variable ArrayList, variable String and variable items. However, if I add {curly braces} then the code compiles with no errors. Why might this be? Is there some ambiguity on the if clause without them?

  • Calling SetWindowsHookEx inside VS2008 debugger always returns NULL

    - by SoMoS
    we're working on a .Net application that does a low level keyboard hook. When we call the SetWindowsHookEx running inside the debugger the call always fail. When running from the compiled executable everything works fine. If we attach to the processs the the SetWindowsHookEx has been called everything works too. I've read somewhere (I can not remember) that VS already does a low level keyboard hook but this shouldn't be a problem as there is the CallNextHook function. Someone knows what's happening? EDIT: The code is pretty straigfoward, the exception is thrown inside debugger but not outside. Public Sub New() m_callback = New NativeMethods.KeyboardHookDelegate(AddressOf KeyboardCallback) End Sub Public Sub Start() m_handle = NativeMethods.SetWindowsHookEx(NativeMethods.HookType.WH_KEYBOARD_LL, m_callback, Marshal.GetHINSTANCE(Reflection.Assembly.GetExecutingAssembly().GetModules()(0)).ToInt32, 0) If m_handle = 0 Then Throw New Exception() End If End Sub

  • Trying to compile MobileSubstrate addon - Undefined symbol

    - by eWolf
    Hi! I went through this tutorial to create a MobileSubstrate addon. I could compile the example hook without errors. But as soon as I add #import <SpringBoard/SBAwayController.h> in ExampleHookProtocol.h and SBAwayController *awayController = [SBAwayController sharedAwayController]; in ExampleHookLibrary.mm (as the first line of the __$ExampleHook_AppIcon_Launch function) I get the following error message when attempting to make (triggered by the latter change): Undefined symbols: "_OBJC_CLASS_$_SBAwayController", referenced from: __objc_classrefs__DATA@0 in ExampleHookLibrary.o ld: symbol(s) not found collect2: ld returned 1 exit status make: *** [ExampleHook.dylib] Error 1. The header file for SBAwayController is located in /var/toolchain/sys30/usr/include/SpringBoard, just like SBApplicationIcon.h, which is used by the ExampleHook. I'm compiling on my iPod touch 2G. Can anyone help me? Thanks in advance, Eric

  • how to pass an xml file to lxml to parse?

I have seen someone suggest using the latex function from the hmisc package to manually iterate over the table and write it out in latex manually, including the newline, but this seems like a bit of a faf !

  • Why this structure should have 48 bytes

  • Proper way of utilizing gearman with my php application.

    - by luckytaxi
    For now I just want to use Gearman for background processing. For example, I need to email a recipient that they have a private message waiting for them once the sender submits their message into the DB. I assume I can run the worker/client and server on my primary server but I have no problems offloading some of the tasks to a different web server. Anyways, my question is how do I handle multiple "functions?" Let's say I need a job that handles the email portion and a job to handle image manipulation. Can I have multiple functions in the worker? I've followed a couple of examples I found online but each example only shows one function being initialized. Do I have to start up multiple "workers" to handle multiple functions?
