  • JQuery - Iterate through SELECT options

    - by user208662

How do I use JQuery to display the value and text of each option in a SELECT element? I just want to display them in an alert() box. Thank you!

  • Mysql console slow on import of huge sql files

    - by Kennethvr
    My import of sql via the mysql console is rather slow and as our sql file is increasing every day I would like to know if there are any alternatives on how to import a sql file faster. Changing to oracle or other systems is no option, the configuration has to stay the same. Currently the sql file is: 1.5 Gb I'm on Wamp with Apache 2.2.14, PHP 5.2.11 and MySQL 5.1.41. Any suggestions?

  • Copying files and dirs on remote server while excluding some of them

    - by llaskin
    Server 1 is connected to Server 2 via SSH. We know this: I can execute a command such as " ssh server2 "cp -rv /var/www /tmp" " which will copy the entire /var/www dir to /tmp. However inside of /var/www we have the following structure(sample LS output below) $ ls /web1 /web2 /web3 file1.php file2.php file3.php How can I execute a cp command that will exclude /web1, /web3, file1.php and file3.php (obviously just copying web2 and file2 is not an option since there are significantly more files than just 6)

  • How to script a URL screenshot without X?

    - by cwopen
    I'd like to automate a 'screenshot' of arbitary URL's using a Linux build that doesn't have X installed. There appears to be some (costly) web services to do this, but I specifically want something I can do locally. Tried imagemagick without much success, though Mozilla used to have a command line option to do it?

  • Efficient quaternion angular velocity

    - by user3736210
    I have an orientation expressed with a quaternion and an angular velocity expressed as either a quaternion or a number (radians per second around the original orientation). I understand how to do this using conversion to axis-angle but that method is rather computationally expensive and is not a realistic option. How would I go about modifying the orientation quaternion given a time interval (in seconds)? I need a solution for both cases (the quaternion and the number).

  • Drupal 7: Rename files on upload (via filefield)

    - by Eugene
    Looking for a way to rename files that are uploaded by users through a filefield. For example, rename user profile photos using uniqid. I found a good solution for D6 here: http://www.wesjones.net/home/2011/03/drupal-6-how-to-change-filename-on-upload but can't find anything for D7. Another option is to use File (Field) Paths, but (1) the module causes warnings on my setup and (2) seems to be a bit of an overkill to install a general module for a very specific purpose.

  • What's the quickest way to dump & load a MySQL InnoDB database using mysqldump?

    - by Josh Schwartzman
    I would like to create a copy of a database with approximately 40 InnoDB tables and around 1.5GB of data with mysqldump and MySQL 5.1. What are the best parameters (ie: --single-transaction) that will result in the quickest dump and load of the data? As well, when loading the data into the second DB, is it quicker to: 1) pipe the results directly to the second MySQL server instance and use the --compress option or 2) load it from a text file (ie: mysql < my_sql_dump.sql)

  • Autorun a removable device in Linux

    - by Zloy Smiertniy
    I have a removable device setup so it autoruns when plugged into a Windows machine and pops up a message giving the owner's information, so it can be returned if lost. Is there a way to do this in Linux as well? It doesn't need to be complex, it can be an option in a right-click menu, or a splashscreen, or anything.

  • How to set user environment variables in Windows Server 2008 R2 as a normal user?

    - by likm
    In older versions of Windows, it was just open the Control Panel, select the System applet, select the Advanced tab, and then hit the Environment variables button. As a normal user, you could edit the "User variables" but not the "System variables". In Windows Server 2008 R2, if I try to hit the Advanced System settings option in the System applet, it prompts for the Administrator password.

  • Debugging on the production server in Rails

    - by ming yeow
    how do you effectively debug on live server in rails, whether on a beta/production server? I tried modifying the file directly on the server, and restarting the app, but the changes does not seem to take effect, or takes a long time to (caching?) I also tried to do "script/server production" locally, but that is very slow The other option is to code and deploy, but that is very inefficient. Anyone has any insights as to how they do this efficiently?

  • How can I tell the number of replacements in a formatter string?

    - by sdanna
    Given the following method: (real method has a few more parameters, but the important ones are below...) public string DoSomething(string formatter, params string[] values) { // Do something eventually involving a call to String.Format(formatter, values); } Is there a way to tell if my values array has enough objects in it to cover the formatter, so that I can throw an exception if there aren't (short of doing the string.Format; that isn't an option until the end due to some lambda conversions)?

  • ETA on Smart Device Projects for Visual Studio 2010

    - by Vaccano
    I really want to upgrade to Visual Studio 2010. But since I do a lot of development for the Pocket PC version of Windows Mobile I cannot. (I develop for a Symbol device that does not support Windows Phone 7, so that is not a option.) Does any one know any kind of time frame of when Microsoft plans to add support for Smart Device Projects into Visual Studio 2010

  • Maximum capabilities of MySQL

    - by cdated
    How do I know when a project is just to big for MySQL and I should use something with a better reputation for scalability? Is there a max database size for MySQL before degradation of performance occurs? What factors contribute to MySQL not being a viable option compared to a commercial DBMS like Oracle or SQL Server?

  • Javascript returns Nan in IE, FF ok

    - by user350184
    im very new to javascript, and writing this script to add up a shopping cart and print out subtotals and totals. it works in FF but not in IE. this function is called by onclick of one of three select options with a value of 0-25. it is in a js file called in the head. what it does is get the selected values as variables, parseint them, adds and multiplies, and changes the innerHTML of the table to reflect the subtotals, and total. FF does it great, but IE gives Nan. ive tried rewriting it a number of different ways, and many translations still work in FF but not IE8. ive made sure the variables and form id's arent repeated. function gen_invoice() { var scount = parseInt(document.shopcart.studentcount.value, 10); var ycount = parseInt(document.shopcart.youthcount.value, 10); var fcount = parseInt(document.shopcart.facultycount.value, 10); //html output source is 3 selects like this, with diff ids and names: //<select name="studentcount" id="studentcount"> //<option onclick="gen_invoice()" value="0">0 </option></select> var cardcost = parseInt(document.shopcart.cardprice.value, 10); //cardcost comes from hidden input value: //<input type="hidden" id="cardprice" name="cardprice" value="25"> var totalsum = scount + ycount + fcount; var grandtotal = totalsum * cardcost; document.getElementById('s_price').innerHTML = scount * cardcost; document.getElementById('y_price').innerHTML = ycount * cardcost; document.getElementById('f_price').innerHTML = fcount * cardcost; document.getElementById('grand').innerHTML = grandtotal; //.... } ...after this there are 3 long loops for writing out some other forms, but they dont work in IE either because they depend on the selected values to be an integer. this part happens first and returns Nan, so im sure the problem is here somwhere. I have literally hit my head on the table over this. You can imagine how frustrating it is to be able to write the entire rest of the site beautifully, but then fail at adding 3 numbers together. help please!

  • Toggling between states on 3 containers in jQuery

    - by Saif Bechan
    Hello, i have an php/mysql/ajax auction application application. Now there is a section that can have 3 states. State one, the user can place a bid.(Bid button is shown) State two, the user has to wait before he can place a new bid(number of sec is shown) State three, the user has an auto bidding system enabled.(The price maximum and amount ate shown). Now i get these values trough jquery ajax, and i want to present the user the right section. Now the code i have is as follows: if(data[i].bidwait >= 0 && data[i].amount == ''){ // In this section the user has no autobiddings, and can place a bidding $(productContainer+' .bid-wrapper').removeClass('none'); $(productContainer+' .bidwait-wrapper').addClass('none'); $(productContainer+' .autobid-wrapper').addClass('none'); }else if(data[i].bidwait < 0 && data[i].amount == ''){ // In this section the user has to wait the amount of sec to place a new bid $(productContainer+' .bid-wrapper').addClass('none'); $(productContainer+' .bidwait-wrapper').removeClass('none'); $(productContainer+' .autobid-wrapper').addClass('none'); $(productContainer+' .bidwait-text').text(data[i].bidwait * -1); }else{ // In the last section the user has the auto bidder enabled, so that is shown $(productContainer+' .bid-wrapper').addClass('none'); $(productContainer+' .bidwait-wrapper').addClass('none'); $(productContainer+' .autobid-wrapper').removeClass('none'); $(productContainer+' .amount').html(data[i].amount == 0 ? '&#8734;' : data[i].amount); $(productContainer+' .maxprice').html(data[i].maxprice == 0 ? '&#8734;' : data[i].maxprice); } This looks like an awful lot of code for something so small. I was wondering if there is an easier method to accomplish such a thing. Speed is a huge issue for me because this has to run every second in the users browser. If there is no other option i am just going to remove this option and go with a no ajax approuch. If you have been, thank you for reading!

  • What is the command-line input to produce the javadoc?

    After writing all the comments inside the code about the javadoc such as /** * This method compares the student's answer to the standard answer * @param ans The student's answer * @return True for correct answer; False for incorrect answer */ boolean compareAnswer(int ans); I guess it starts with : javadoc [optionss] [packages|files] I'm not sure what is the regular or default [option] and how can I say to produce it in my current home directory?
