  • Form variable does not refresh with ajax call

    - by ChrisOPeterson
    I'm building a simple email sending form and wanted to make it with ajax. The form submits correctly the first time but if you make any subsequent changes to the text in the form and then submit again then jquery does not pick up on the changes and posts the old data. Whats going on? <script type="text/javascript"> var $j = jQuery.noConflict(); $j(document).ready(function() { var submit_url = "mail_submit.php"; var send_email = $j("#sendemail"); send_email.click(function() { var form = $j("#post"); $j.post(submit_url, form.serialize(), function(data) { alert(data); }); }); });

  • Getting ftp_put progress

    - by Billiam
    I have a php script on a web server that uploads a file to another remote server via ftp_put. How can I display the current upload progress to the user? The only similar system I've seen is for file uploads from the user, with ajax requests to check the local size of the uploaded file on the server. The equivalent system would be ajax requests to the web server, that then checked file sizes on the remote server and returned that data to the user's clientscript. This seems horribly inefficient to me. Is there a better way?

  • Is it possible to talk to the iPhone simulator/device.

    - by Plumenator
    I need to automate the build/deploy process for my iphone applications from a script. I can use xcodebuild to build the project, then use Applescript to deploy and debug/run the application. Assuming the application will stop by itself after a while, I need to collect the generated logs for verification. But the problem is I have no way to know when the application ended from outside of the application itself. If the running time is fixed, I can again use Applescript to stop the application (Cmd+Shift+Enter). So there has to be a way to connect to the device/simulator and wait on the application somehow.

  • How can I efficiently retrieve a large number of database settings as PHP variables?

    - by Steven
    Currently all of my script's settings are located in a PHP file which I 'include'. I'm in the process of moving these settings (about 100) to a database table called 'settings'. However I'm struggling to find an efficient way of retrieving all of them into the file. The settings table has 3 columns: ID (autoincrements) name value Two example rows might be: 1 admin_user john 2 admin_email_address [email protected] The only way I can think of retrieving each setting is like this: $result = mysql_query("SELECT value FROM settings WHERE name = 'admin_user'"); $row = mysql_fetch_array($result); $admin_user = $row['value']; $result = mysql_query("SELECT value FROM settings WHERE name = 'admin_email_address'"); $row = mysql_fetch_array($result); $admin_email_address = $row['value']; etc etc Doing it this way will take up a lot of code and will likely be slow. Is there a better way? Thanks.

  • Shorter GUIDs than hashing a user id?

    - by Alex Mcp
    I'm wondering how Instapaper (bookmarklet that saves text) might generate URLs for their bookmarklet. Mine has a script src of something similar to www.instapaper.com/j/AnJHrfoDTRia The quality of these URLs is that they need to never collide, and not be really guessable (so other people can't save to your account). I know a simple approach might be to MD5 their email address (presumed to have been checked on signup for uniqueness), but then I'd end up with a super long string. This isn't a huge issue, but I'm wondering what techniques there are for shorter GUIDs that won't collide too often (this is obviously the tradeoff, but 12 characters above is pretty short in my opinion)

  • git - how do we verify commit messages for a push?

    - by shovas
    Coming from CVS, we have a policy that commit messages should be tagged with a bug number (simple suffix "... [9999]"). A CVS script checks this during commits and rejects the commit if the message does not conform. The git hook commit-msg does this on the developer side but we find it helpful to have automated systems check and remind us of this. During a git push, commit-msg isn't run. Is there another hook during push that could check commit messages? How do we verify commit messages during a git push?

  • Creating a custom categories widget

    - by Scott B
    The code below is an attempt to take the WP_Widget_Categories class and use it as the basis for a custom categories widget based on the default categories widget.

  • How do I get MSBuild Task to generate XML Documents when building a solution?

    - by toba303
    I have a solution with lots of projects. Each project is configured to generate the XML documentation file when building in Debug-Mode (which is default). That works when I build in Visual Studio 2008. In my build script on my integration server I advise MSBuild to build the whole solution, but it won't generate the documentation files. What can I do? I already tried to explicitly give the Debug-Condition to the build process, but it makes no difference. <Target Name="BuilSolution"> <MSBuild Projects="C:\Path\To\MySolution.sln" targets="Build" Properties="SolutionConfigurationPlatforms='Debug|Any CPU'"/> </Target> There seem to be some ideas to solve this problem when building single projects, but I can't afford to do this, so I need a hint for doing it this way. Thanks in advance!

  • How can I make this run on all my files automatically? YUI Compressor for Visual Studios

    - by chobo2
    Hi So I found this page http://blog.lavablast.com/post/2009/05/YUI-Compressor-for-Visual-Studio.aspx and how to put YUI compressor into Visual studios(I am using visual studios 2010 express). So it got me thinking can I somehow set it in my project to always take my "development scripts" and minify them automatically. Right now if I make a change to my script I have to remember to minify it once I am done otherwise I could be using a out to day version. So it would be cool if I could just set up like so when I build it takes all my development scripts and then minifys them. How could I do something like this?

  • Figuring out Host's Top Domain with Javascript

    - by timeitquery
    Is there a way to figure out what the top domain for the hostname of the current page is? The problem I have is that the script could be on .com domain, or in an international domain like .co.uk So for: jobs.telegraph.co.uk - top domain is:telegraph.co.uk jobs.nytimes.com - top domain is nytimes.com The problem is that location.hostname , and the document.domain give the entire domain. One route is to have a list of all TLDs (too much to carry around) and parse based on that. Another route was if 2 characters after last ".", than internationaltion - hence last two are the TLD, but that does not hold true for all international domains.

  • How do I specify the regular expression to disable the use of underscores after the '@' sign in php for email validation?

    - by Qlidnaque
    Currently the following email in the script validates even though there are no underscores indicated in the second part of the regular expression validation after the '@' sign. How do I make underscores invalid in the second part of the email? <?php $email = 'firstname.lastname@a_aa.bbb.co_m'; $regexp = "/^[^0-9][A-z0-9_]+([.][A-z0-9_]+)*[@][A-z0-9]+([.][A-z0-9]+)*[.][A-z]{2,4}$/"; if (preg_match($regexp, $email)) { echo "Email address is valid."; } else { echo "Email address is <u>not</u> valid."; } ?>

  • Pre-loading external files (CSS, JavaScript) for other pages

    - by Jason Young
    I'm curious if there is an efficient way to wait for the front page of a site to load, and then pre-load CSS and script files that I know will likely be needed for the other pages on the site. I want the front page of the site to be as fast as possible (lean and mean). It's likely that the user will not immediately click on a link. Since there will likely be some idle time, this seems like an opportune time to pre-load some of the external assets. Pre-loading should cause them to become cached. When the user does click on another page, the only request needed will be for the content and possibly some images, etc. Has anyone done this? Is it a bad idea? Is there an elegant way to implement it?

  • Unity 2D Instantiating a prefab with it's components

    - by TazmanNZL
    I have some block prefabs that I add to an array of game objects: public GameObject[]blocks; Each prefab has a BoxCollider2D, Script & Rigidbody2D components. But when I try to instantiate the prefab in the scene it doesn't appear to have the components attached? Here is how I am instantiating the prefab: for (int i = 0; i < 4; i++) { for (int j = 0; j < gridWidth; j++) { blockClone = Instantiate (blocks [Random.Range (0, blocks.Length)] as GameObject, new Vector3 (j, -i-2, 0f), transform.rotation) as GameObject; } } What am I doing wrong?

  • Eclipse + CVS use custom commit

    - by WizKiranPuttur
    Hi All, My admin has set up the "cvs commit" in a very non traditional way, instead of typing "cvs commit" I use the admin provided "scriptname modified file" to checkin the file to CVS. I am using Eclipse to my day to day work and till now I am using the Eclipse CVS Plugin to checkout the repo,update,compare,etc and use the command line to checkin. I am getting annoyed by having to go to command line to do the commit, is there any way I can make Eclipse accept when I say commit it invokes the admin script instead of "cvs commit" ? I spoke to Admin and moving the under the cvs pre-commit hooks is not an option. What can I do ? I know fair amount of "Java" I am willing to do some changes to CVS plugin if I know how and where. Thanks

  • How do I change the Unit:Characters in Matlab?

    - by Jonas
    For portability, I set the units of my GUIs to 'characters'. Now I have a user who wants to use Matlab on his netbook, and the GUI window is larger than the screen (and thus cropped at the top). I think I could try and write something in the openingFcn of the GUI that measures screen size and then adjusts the GUI accordingly, but I'd rather avoid that, because I then need to deal with text that is bigger than the text boxes, etc. What I'd rather like to do is somehow adjust the unit 'character' on his Matlab installation. None of the font sizes in the preferences seem to have an effect on unit:character, though. Does anyone know whether there's a setting for that, which can be changed from within Matlab (I don't mind if it's something that is reset at every reboot, since I can just put it into the startup script)?

  • SQL Server Express: Failed to add primary key after creating a database table

    - by Syd
    Scenario: I have created a database table. And when I tried to add a primary key (using the SQL Server Management Studiio) to the table, it failed with an error message "Saving changes is not permitted. The changes you have made requrie the following tables to be dropped and re-created. You have either made changes to a table that can't be recreated or enabled the option Prevent savign changes that require the table to be re-created." The environment is Windows 7. I have earlier installed it on a Windows XP SP2 and it worked. And yes, my table is empty (freshly created). My current workaround is to run the "Drop and Create" script. The other alternative is to create the primary key before I save the table. Is this a bug or a limitation with the Express version?

  • Replacing emty csv column values with a zero

  • Something wrong with deinstallation of GIT in Windows...

    - by Stef Joosten
    I tried to remove GIT on my windows-XP, by means of the Windows/Configuration/Software menu. After some error message (which I cannot remember), it removed all files. I checked it, and there are no files with ptp in the name left on the entire system. A problem remained however: each time I opened windows-explorer, a nasty error message came calling for a dll file that wasn't there anymore. Anyone know what is going on here? A wild guess: could there be any interference between svn and git, if certain files are linked to both git and svn? Personally, I went to the registry. I found that many traces to GIT are left in the registry after deinstalling GIT the "windows-way". I removed each one carefully by hand, which seems to have solved my problem. This is of course a dangerous path, but I had no choice. Perhaps it is a good idea to look into the Windows-deinstallation script very carefully.

  • Changing a project's files based on solution in Visual Studio 2008

    - by emddudley
    In one C# solution I have several projects that share a CommonAssemblyInfo.cs file, so that certain assembly attributes are shared across all projects. This works fine so long as I only have one CommonAssemblyInfo.cs file. However I have several solutions (applications) which use these projects, and each solution has its own version of CommonAssemblyInfo.cs. How can I make the projects use a different CommonAssemblyInfo.cs file depending on which solution they are in? In the end I want my assemblies to have attributes specific to the solution they were compiled from. I don't think I can make them files Solution files because they can't all be in the same directory with the same filename. I can't use pre-build events because I don't have a particular project which is always built first. I would prefer not to use a build script because I would like to be able to build and run the solutions through the Visual Studio environment.

  • MatLab plot part of surface

    - by Kristian
    Say I have the following script: u = -5:.2:5; [X,Y] = meshgrid(u, u); Z = cos(X).*cos(Y).*exp(-sqrt(X.^2 + Y.^2)/4); surf(X,Y,Z); Is there anyway that I can make MatLab plot only parts of the surface? Say, for instance, I just want to plot a single point, or a single grid, what can I do? I thought perhaps to plot a single point I could use: surf(X(1,1), Y(1,1), Z(1,1)) But then I get the error message: ??? Error using ==> surf at 78 Data dimensions must agree. I would really appreciate some input/help here. Thanks in advance :)
