• JavaScript - Is it possible to get height from div in separate page?

  - by Kenny Bones

  Hi, I'm wondering, is it possible to collect the height of a specific div container from a separate page with JavaScript? I'm using jQuery btw and I'm in need of comparing heights of div containers. Edit: To clarify a bit more, I load content from a specific div in a separate page using jQuery. This content is faded into a different container with dynamic height. But in the small fraction of time before the content arrives, it shrinks down to it's min-height. What I've done so far is collecting the height of the container before and after the load. But it only works after I've loaded content once. Because I don't have the height before it's been loaded the first time.

• How do you make the script wait for the status of an Ajax get request before continuing?

  - by codeninja

  Basically what I'm doing is checking for the existence of an object, if it's not found, the script will try to load the source file using getScript. I only want to check this once though then return true or false to the function that calls fetch() fetch:function(obj){ ... isReady = false; $.getScript(obj.srcFile,function(){ isReady=true; warn("was able to load object "+key); }); return isReady; } but return kicks in before the script loads =/ later the script is loaded but the function returned false. This is the beauty of asynchronous I suppose... What's the best way to handle this... Maybe I could check again at some other point if the object exists? Or maybe there's a better way to do this where I dont have to potentially lock the browser?

• Rebind a unbind click

  - by Antonio Ortiz

  I am using this library that allows you to create a more elegant alert box (you can even use images!); I used it with a click function and it works! A nice container opens with a close button, GREAT! I noticed if you happen to click more than once on the link you assigned, it keeps firing. So multiple images begin to propagate. I used the unbind method, but it cancels the link permanently (until refresh etc.). I was surprised to see the library doesn't compensate for this little problem, so I am wondering if you could rebind the click when you close the image window so it starts from the beginning. $(".shopFrag").click(function(){ Messi.img("_images/wishlist.jpg"); $(".shopFrag").unbind('click'); });

• Pygame single push event

  - by Miller92Time

  in Pygame i am trying to translate an image by 10% in each direction using each arrow key. right now the code i am using moves the image as long as the key is pushed down, what I want is for it to move only once regardless if the key is still pushed down or not. if event.type == KEYDOWN: if (event.key == K_RIGHT): DISPLAYSURF.fill((255,255,255)) #Clears the screen translation_x(100) draw(1) if (event.key == K_LEFT): DISPLAYSURF.fill((255,255,255)) #Clears the screen translation_x(-100) draw(2) if (event.key == K_UP): DISPLAYSURF.fill((255,255,255)) #Clears the screen translation_y(100) draw(3) if (event.key == K_DOWN): DISPLAYSURF.fill((255,255,255)) #Clears the screen translation_y(-100) draw(4) is there a simpler way of implementing this besides using time.sleep

• converting ip to long string in mysql command !

  - by Mac Taylor

  hey guys I'm trying to use ip2country technique to show my users'flags simple thing to do is to write a sql statement and show users from session table and then query to see if their ip is in what range and show their flags it simple but dengerous becuase when showing 300 users online and fetching from session table and then query once again ip2country table to get the flags there will be surelly memory overusage problem now i wrote a query to make it in one query : SELECT s.session_ip,ipc.* FROM session s left join ip2country ipc ON ipc.ip_lo<=s.session_ip AND ipc.ip_hi>=s.session_ip WHERE s.session_time > '".( time() - 60) )."' now its clear above query is wrong cause ips saved in ip2country table is long string 1000013824 and ips saved in session table are real ip e.g. 193.169.0.0 now i know how to convert from ip to long in php ip2long() but is there any command in mysql to do it with out building another query !?

• When configuring daily backups, which files should I include to be sure I have the MySQL db's

  - by user575599

  I have a dedicated LAMP server with cpanel hosting 100 websites (some of them have MySQL db's). I am currently using the Jungle Disk Server Edition to backup our files from our LAMP server to Amazon S3. Once a week were are backing up the entire cpanel which is an enormous strain on resources but that is a separate issue. Now, what I want to do is to set up a daily job to backup just the HTML files and the MySQL db's. If I just backup the "public_html" folder will my MySQL database info be stored in that directory? Would backing up the public_html folder be enough to recover the db? I can find plenty of resources online about how to manually backup MySQL db's but with a 100 sites, I need it automated. I'm hoping for an easy solution where I can just grab a folder to backup each day.

• How to register a VB.Net User Control with jQuery

  - by BornReady

  Greetings and thank you in advance for the help. I created a user control in VB.NET that uses a jQuery datepicker. I am at an impasse. The code I have works for one datepicker control on the page but because I can only register the client script once, it will not work for multiple instances/datepickers on the same page. What is the best way to go about initiating the jQuery script for this control so I can use it multiple times on one page? Can I append to ClientScript.RegisterStartupScript? Thanks again.

• Modify input stream data on the fly

  - by Frizi

  I would like to implement a std::stream modifier/parser, that is doing data manipulation on the fly. Is it possible to create it in form of stream manipulator? For example, i want to strip all the line comments (from any // to the end of line) out of the stdin and pass it to stdout. string str; istream strippingCin = cin >> stripcomments; while(strippingCin.good()) { strippingCin >> str; cout << str; } There may be also a large file input instead of cin, so i don't want to load full stream data into memory at once. Is it possible without writing my own stream class? Maybe is there another route i should take instead?

• wpf get access to other classes

  - by Calvin

  I am currently working on a wpf application. There are some methods in other classes in which I want to trigger to do some work instead of trying to figure out how to rewrite them in. How is it that I can get to those classes? Would I have to for example instantiate the class? If so, once I instantiate it, how would I be able access them. Keep in mind that these classes have abstract classes on top of abstract classes.

• Is there an efficient way to figure out the headers, cookies, and get/post data being passed to a si

  - by kryptobs2000

  More specifically I'm looking for something, perhaps an add-on for firefox, once enabled it logs all of this information as it's passed to and from the server. I'm doing some web scripting and this would be really handy. If anyone is wondering specifically what I'm doing currently I'm trying to make a script to repost my craigslist ad every 2 days since I handle a few things on there. Might even go so far as to make a simple gui to manage the submissions. I do suspect this goes against the ToS, for that reason I don't plan to release the code. Besides cl is already bad enough with spam, I'm not trying to contribute further to it, figured I'd say what I'm doing for the sake of being honest though. I don't have any bad intentions with this, just some things I've been trying to sell an ad for my pc repair business. I've been reposting some things for months now and so often I just forget to do it.

• setText() without calling onTextChanged()

  - by user1537779

  Is there a way I can set text to an EditTextView, but not trigger its onTextChanged() or afterTextChanged(). In onTextChanged(), I am making a server call to get autocompletes. But once the user selects from the dropdown, I want to set text to the EditTextView, but it again calls the server and shows the dropdown. While I can have a flag not to make server call when selected from dropdown, using the onItemClick() on dropdown(ListView). How can I remove the flag again, if the user tried to edit the text later.

• Grabbing Just The Top Entry From A LINQ Query

  - by Soo

  I basically have a lot of poorly designed code to do something that, I'm sure, can be done far more elegantly. What I'm trying to do is grab the last date from a database table. var Result = from a in DB.Table orderby a.Date descending select new {Date = a}; foreach(var Row in Result) { LastDate = Row.Date.Date; break; } Basically, there's a foreach loop that is designed to run only once. Crappy code! What's a "best practice" way to accomplish the same thing?

• Any Problems Using Samba as a Windows Domain Controller?

  - by maxam

  We're looking to run a Windows domain using Samba+OpenLDAP on Ubuntu as a domain controller. The documentation out there is a bit spotty and out of date, especially when it comes to installation, which features are supported, and how well. Once this is set up, we hope to be able to use integrated authentication of our IIS sites (including Sharepoint) against the domain controller. Anyone out there who has done this already? Anything specific we should watch out for? Or is it not worth the hassle of trying to set up?

• Archiving rows dynamically

  - by Serge

  I was wondering what would be the best solution to dynamically archive rows. For instance when a user marks a task as completed, that task needs to be archived yet still accessible. What would be the best practices for achieving this? Should I just leave it all in the same table and leave out completed tasks from the queries? I'm afraid that over time the table will become huge (1,000,000 rows in a year or less). Or should I create another table ie task_archive and query that row whenever data is needed from it? I know similar questions have been asked before but most of them where about archiving thousands of rows simultaneously, I just need to know what would be the best method (and why) to archive 1 row at a time once it's been marked completed

• Need help with some C# Counting Code

  - by kaywai

  Hi, I'm trying to code a counter in Ninjatrader which uses C# as its programming language. I would like this counter to commence counting upon the completion of the first counter and once it commences counting to consider only the new condition when counting. So, the first counter commences when Close[0] < Close[4]. The second counter commences ONLY after the first counter has reached 9 and its condition for counting is Close[0] <= Low[2]. I don't know how to write the part of the code where the second counter commences counting and its counts are independent of the first counter reaching 9.

• Anyone know how you can get a Google dev phone to make Android apps?

  - by Bobafett

  Hi there, I am thinking about converting my web apps into Android apps to reach the Android market. I do not have an Android phone. Can someone tell me how I can possibly get a Google developer phone (other than going to Google I/O, etc)? I realize this is somewhat of a ridiculous request but I have read blogs of people being enticed by google and offered a free phone to convert their web apps into Android apps. So I figure there is no harm in asking. Any insight would be helpful. Thanks I am also wondering what the cost of the developer phone is once you pay your $25 to enter the android market place as a developer through the developer account.

• R looking for the wrong java version

  - by Veit

  Hi, I installed/uninstalled java jre/jdk now many times and finally installed the older version 1.6.0_17 which is now located at "C:\Program Files\Java\jre6\bin". Now after all if I call 'java -version' within R i can see that R is looking for Java at the old path which is now wrong. The question is: Why is R looking for Java at the wrong path even so the windows path is set correctly? There are no double entrys within the windows path as far as I can see and I restarted R as well as Windows more then once since then. Any Ideas where R takes the wrong path from? On windows shell: $set [..] OS=Windows_NT Path=C:\Program Files\Java\jre6\bin; [..] $ java -version java version "1.6.0_17" Java(TM) SE Runtime Environment (build 1.6.0_17-b04) Java HotSpot(TM) 64-Bit Server VM (build 14.3-b01, mixed mode) within R: $system("java -version") Error: could not open `C:\Program Files (x86)\Java\jre6\lib\i386\jvm.cfg'

• WPF Button on or off coloured state

  - by wonea

  I'm trying to create a set of button which have an off or on state, much a checkbox without the check. Ideally I want the colour to change to represent the two different states off(red), green(on). I've tried setting a control template but this only changes the colour for a selection, then reverts back to it's original colour once the mouse leaves the button's vicinity. <ControlTemplate.Triggers> <Trigger Property="IsPressed" Value="True"> <Setter Property="Background" TargetName="Background" Value="Green"/> </Trigger> </ControlTemplate.Triggers>

• find: missing argument to -exec

  - by Abs

  Hello all, I was helped out today with a command, but it doesn't seem to be working. This is the command: find /home/me/download/ -type f -name "*.rm" -exec ffmpeg -i {} -sameq {}.mp3 && rm {}\; The shell returns find: missing argument to `-exec' What I am basically trying to do is go through a directory recursively (if it has other directories) and run the ffmpeg command on the .rm file types and convert them to .mp3 file types. Once this is done, remove the .rm file that has just been converted. I appreciate any help on this.

• How can I save/print values in my WATCH list in Visual Studio 2008?

  - by Rising Star

  When I attach the Visual Studio 2008 debugger to my web server process, I sometimes browse a large amount of data in my watch list. Suppose I have an array of string variable that I expand to show 20 entries. It seems that the only way to save these values is to copy and paste them one at a time. I have gone so far as to do a screen-shot in order to have a record of what the values were (to refer to later or print a hard copy). Is there an easy way to save and print these values? I am familiar with the new "IntelliTrace" feature in Visual Studio 2010 Ultimate, but it seems overkill for this purpose. I just want to take something like an array of strings and save it for later reference once I've stopped the debugger. What's a good way to do this?

• Getting information about where c++ exceptions are thrown inside of catch block?

  - by tfinniga

  I've got a c++ app that wraps large parts of code in try blocks. When I catch exceptions I can return the user to a stable state, which is nice. But I'm not longer receiving crash dumps. I'd really like to figure out where in the code the exception is taking place, so I can log it and fix it. Being able to get a dump without halting the application would be ideal, but I'm not sure that's possible. Is there some way I can figure out where the exception was thrown from within the catch block? If it's useful, I'm using native msvc++ on windows xp and higher. My plan is to simply log the crashes to a file on the various users' machines, and then upload the crashlogs once they get to a certain size.

• Continuously reading from a stream in C#?

  - by Damien Wildfire

  I have a Stream object that occasionally gets some data on it, but at unpredictable intervals. Messages that appear on the Stream are well-defined and declare the size of their payload in advance (the size is a 16-bit integer contained in the first two bytes of each message). I'd like to have a StreamWatcher class which detects when the Stream has some data on it. Once it does, I'd like an event to be raised so that a subscribed StreamProcessor instance can process the new message. Can this be done with C# events without using Threads directly? It seems like it should be straightforward, but I can't get quite get my head around the right way to design this.
