  - by Jason

  Hello, I am quite a newbie to jQuery/ajax but am having a problem with my site that im making. Basically at first the page loads fine. On the boxes is a fade caption, when the title of the caption is clicked you are brought to an ajax page. Once you use the 'Back' button on browser, or the 'Back to list' button i've made the caption fade plugin no longer works and the box i had previously clicked is no longer clickable. can anyone help? heres my website: http://www.jcianfrone.com/testing jquery: h**p://www.jcianfrone.com/testing/script.js HTML: <div id="pageContent"> <div class="item"><a href="#page6"><img src="images/wrk-kd.jpg" width="286" height="200" alt="Koodikkki"></a><span id="caption"><a href="#">Title</a><p>Description</p></span></div> <div class="item"><a href="#page7"><img src="images/wrk-kd.jpg" width="286" height="200" alt="Koodikkki"></a><span id="caption"><a href="#">Title</a><p>Description</p></span></div> <div class="item"><a href="#page8"><img src="images/wrk-kd.jpg" width="286" height="200" alt="Koodikkki"></a><span id="caption"><a href="#">Title</a><p>Description</p></span></div> <div class="item"><a href="#page9"><img src="images/wrk-kd.jpg" width="286" height="200" alt="Koodikkki"></a><span id="caption"><a href="#">Title</a><p>Description</p></span></div> </div> Many thanks in advance

• Using MSBuild 4 command line to publish ASP.NET web application

  - by meandmycode

  In previous msbuild we used the target '_CopyWebApplication' in order to build and convert the source of a project into a published site, this worked OK, but wasn't ideal. In .NET 4, the publishing process is somewhat more sophisticated and additionally seems a bit of a black box to understand. Whilst packages look great, I cannot fully understand how they can be harnessed by a build server, the build server would not get any manifest information, and equally, something (msbuild?) is CREATING this manifest information FROM the project file. In our build server, I ideally want to say, here is my csproj file, deploy it by the package configuration 'x'. I'm trying to understand the workflow I need to make this happen. Right now when I use _CopyWebApplication, the result is different to doing a publish from visual studio 2010, primarily that web.config transforms aren't processed, and obviously msdeploy isn't involved at all. Can somebody point me in the right direction, I believe I need to get msbuild to do the equiv of 'Build Deployment Package', and then use msdeploy to deploy this from our build server to our CI testing environments. I know this is a very vague post, but I hope somebody can give me some hints, I'll be continuing research also, so if I make any progress, I'll post my findings here. Thanks in advance, Stephen.

• How to use an Audio Unit on the iPhone

  - by CodeToaster

  I'm looking for a way to change the pitch of recorded audio as it is saved to disk, or played back (in real time). I understand Audio Units can be used for this. The iPhone offers limited support for Audio Units (for example it's not possible to create/use custom audio units, as far as I can tell), but several out-of-the-box audio units are available, one of which is AUPitch. How exactly would I use an audio unit (specifically AUPitch)? Do you hook it into an audio queue somehow? Is it possible to chain audio units together (for example, to simultaneously add an echo effect and a change in pitch)? EDIT: After inspecting the iPhone SDK headers (I think AudioUnit.h, I'm not in front of a Mac at the moment), I noticed that AUPitch is commented out. So it doesn't look like AUPitch is available on the iPhone after all. weep weep Apple seems to have better organized their iPhone SDK documentation at developer.apple.com of late - now its more difficult to find references to AUPitch, etc. That said, I'm still interested in quality answers on using Audio Units (in general) on the iPhone.

• Jquery/YUI - Find image and set CSS to display:none

  - by danit

  I have the following image in a CMS that I want to hide, I dont really want to change source code but would like to hide a specific image which does not have a class applied. Here is the HTML: <td class="right side"> <a title="Show only topic 1" href="view.php?id=3&topic=1"> <img alt="Show only topic 1" src="http://vl3.co.uk/iphone/pix/i/one.gif"/> </a> <br/> </td> I want to hide the <a> and the <img>, bare in mind the title and alt tag can be different so cant use that as an identifier. I presume I could use .find() and then use .parent() to set the <a> to display: none; thus hiding the img? Im inlcuding the jQuery library, however the CMS has YUI included out of the box so if anyone has a YUI method it would be appreicated.

• FormMethod.Get and query string parameters

  - by parminder

  Hi Experts, I am working on a website in asp.net mvc. I have to show a view where user put some search values like tags and titles to search. I want to use the same Index method for that. I have make my form to use formMethod.Get to send the parameters as querystring. so here is the method [HttpGet] public ActionResult Index(string title, string tags, int? page) { if (string.IsNullOrEmpty(title) return View(null); var list = GetSomeData(); return View(list); } here is my view <div id="searchBox"> <% using (Html.BeginForm(null, null, FormMethod.Get)) { %> <table> <tr> <td> <input type="hidden" id="isPosted" name="isPosted" value="1" /> I am looking for <%=Html.TextBox("Title")%> Tags: <%=Html.TextBox("Tags")%> <input id="search" type="submit" value="Search" /> </td> </tr> </table> <% } %> So when the user first visit the page, he will see only two text boxs and a button. but when he types something in the title and tags and click the search button i will load the view with some data. Now the problem is when i type something in title and tags box and click search, they are received in the method, but are not visible in the url. Is there anything i m doing wrong. help will be appreciated. Regards Parminder

• Debugging in VS 2008 locks a stored procedure

  - by larryq

  Hi everyone, I've got a strange one here. I have a .Net executable that, under the hood, calls a few stored procedures. For whatever reason, one of the stored procs hangs when I'm debugging. If I run the executable outside of visual studio things go fine, including this stored proc. It's when I'm debugging that this hangs, and it really hangs. If I stop the debugging session the IDE freezes and I have to kill it via taskmanager. I know which stored procedure has the trouble, as well as the actual statement within it that's the problem. It's calling an update statement that doesn't stand out as particularly special. I can run the identical statement (and the stored procedure itself) from SQL management studio wtih no problem. And, as I mentioned, the exe runs just fine outside the debugger. If I use the SQL activity monitor to see why things are hanging, the wait type says PREEMPTIVE_DEBUG. I'm not sure if that's helpful but if you need more info I'll try to get it to you. I've rebooted my machine (the SQL Server in question is on this box as well) and that didn't do anything, nor did rebuilding the executable. I'm scratching my head on this one and if you have any ideas what to check on next, I'm be happy to listen. Thanks!

• Send document to printer from web page

  - by FiveTools

  I have a webpage that activates a print job on a printer. This works in the localhost environment but does not work when the application is deployed to the webserver. I'm using the PrintDocument class from the .net System.Drawing.Print namespace. I'm now assuming the printer has to be available to the application on the remote server? Any suggestions on how I would get this to work? PrintDocument pd = new PrintDocument(); PaperSource ps = new PaperSource(); pd.DefaultPageSettings.PaperSize = new System.Drawing.Printing.PaperSize("Custom", 1180, 850); pd.PrintPage += new PrintPageEventHandler (this.pd_PrintPage); // Set your printer's name. Obtain from // System's Printer Dialog Box. pd.PrinterSettings.PrinterName = "Okidata ML 321 Turbo/D (IBM)"; //PrintPreviewDialog dlgPrintPvw = new PrintPreviewDialog(); //dlgPrintPvw.Document = pd; //dlgPrintPvw.Focus(); //dlgPrintPvw.ShowDialog(); pd.Print();

• JavaScript problems in one IIS server but not another

  - by DanyW

  Hi everyone, I have a problem that only occurs in one environment. On this particular page, somewhere in the top half of the element, an array is created and populated. This is later used in the onfocus event handlers of various controls. I use Firebug to debug the page and discovered the problem. In our dev environment the array is indeed created and populated. In our staging environment this block of script is not executed! I put a break point where the array is instantiated and it's never hit in staging, but is hit in dev. I'm really puzzled what aspects of the two environments can possibly affect this? We use aptimize on the staging box but it has been turned off for this particular website. I compared the page sources and they're identical! The only difference is bits of content since they are served by a CMS. Any ideas please? I'm quite stuck on this. Cheers, Dany.

• How do I disable the network connection from .Net without needing admin priveledges?

  - by Brad Mathews

  I may be SOL on this but I thought I would give throw it out for possible solutions. I am writing a computer access control service to help me control my kids' computer use. Plan on open sourcing it when I have it working. It is written in VB.Net and needs to work on XP through 7. I am running into all sorts of security and desktop access issues on Windows 7. The service needs to run as admin to execute the NetSh command to disable the network. But I cannot interact with the desktop from the service so I IPC to a UI to handle other stuff, but I still cannot detect from the service if the desktop is locked. Argghh! I could get it all working from a hidden windows form app if I could just lick the one piece that needs admin permissions: disabling the network. It does no good if a kid logs on and denies the popup asking if the program should run as administrator and he says no. Also windows 7 will not start a program set to run as admin using HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run Anyone know how to get this working? Or have an outside the box solution? Thanks! Brad

• How to make a small flash swf with ComboBox in Actionscript 3?

  - by Sint

  I have a pure Actionscript 3 project, using flash.* libraries, compiles down to about 6k (using mxmlc). Program handles about 1k shapes, a few sprites, a sockets connection, works great (tastes less filling). Now, how would I add a ComboBox control without incurring excessive bloat? More specificially, I would like to keep the size under 100k. So far I have tried: Adobe mx.controls ComboBoxexample - simple mxml example compiles to 200+k both on my main Linux Box using mxmlc and in Windows using Flash Builder 4 Yahoo Astra - uses mx libraries underneath(so as bloated as Adobe?), plus does not contain exact ComboBox Keith Peter's MinimalComps - seems small, but far from providing ComboBox functionality SPAS (Swing Package for Actionscript) - compiles to 130k, but alpha version of ComboBox does not let me adjust height... asuilib - compiles to 40k, unfortunately this ComboBox does not provide for scrolling items...if it does not fit on screen no way to scroll to it Now my questions: Is there a way to lower size for projects importing mx.controls ? Maybe there is a way to fix SPAS or asuilib ComboBoxes? Perhaps, there are some other libraries which provide a ComboBox(or DropList)?

• as3 tracking number value of variables

  - by Wade D Ouellet

  Hi, I have a bunch an as3 game going. In my game when newCrag hits egg_mc the score gets added. // Add the score var newScore:score_mc; newScore = new score_mc(); addChild(newScore); newScore.x = 20; newScore.y = 20; newScore.score_txt.text='0/15'; var score:Number=0; function getEggs(event:Event):void { if(event.target.hitTestObject(MovieClip(root).newCrag) && event.target is egg_mc) { sndEgg.play(); if(event.target.stage) { event.target.parent.removeChild(event.target); } // Increase score score++; newScore.score_txt.text = "" + score + '/15'; } } I am trying to refer to the number value of the score using if statements. I need to change the speed variables based off the number that is inside the score box. var speed:Number if(score > 10 || score == 10) { speed=20; trace("speed3"); } else if(score > 5 || score == 5 && score < 10) { speed=18; trace("speed2"); } else { speed=14; trace("speed1"); } However, this part of the code is not working. Any help would be much appreciated. Thanks, Wade

• How to gray out HTML form inputs?

  - by typoknig

  What is the best way to gray out text inputs on an HTML form? I need the inputs to be grayed out when a user checks a check box. Do I have to use JavaScript for this (not very familiar with JScript) or can I use PHP (which I am more familiar with)? EDIT: After some reading I have got a little bit of code, but it is giving me problems. For some reason I cannot get my script to work based on the state of the form input (enabled or disabled) or the state of my checkbox (checked or unchecked), but my script works fine when I base it on the values of the form inputs. I have written my code exactly like several examples online (mainly this one) but to no avail. None of the stuff that is commented out will work. What am I doing wrong here? <label>Mailing address same as residental address</label> <input name="checkbox" onclick="disable_enable() "type="checkbox" style="width:15px"/><br/><br/> <script type="text/javascript"> function disable_enable(){ if (document.form.mail_street_address.value==1) document.form.mail_street_address.value=0; //document.form.mail_street_address.disabled=true; //document.form.mail_city.disabled=true; //document.form.mail_state.disabled=true; //document.form.mail_zip.disabled=true; else document.form.mail_street_address.value=1; //document.form.mail_street.disabled=false; //document.form.mail_city.disabled=false; //document.form.mail_state.disabled=false; //document.form.mail_zip.disabled=false; } </script>

• How to decode a html string using xslt

  - by John ClearZ

  I am trying to style an rss feed using xslt. I want to display an image that is stored in the tag on the feed. The problem is it is encoded to display as text on the page instead of being rendered. The following is an example of part of the string. 1). <description>&lt;img src="http&amp;#58;&amp;#47;&amp;#47;buavhw.blu.livefilestore.com&amp;#47;y1ppCokLxFJSG2cmyPdvg... I had to add extra coding to the string above to get it to appear properly here. The string below is how it appears when I paste it directly into the text box. 2). <description><img src="http&#58;&#47;&#47;buavhw.blu.livefilestore.com&#47;y1ppCokLxFJSG2cmyPdvg... If I copy and paste it again from the preview window it only then becomes the following string. 3). <description><img src="http://buavhw.blu.livefilestore.com/y1ppCokLxFJSG2cmyPdvg...

• Make Ant's delete task fail when a directory exists and is not deleted but not when it doesn't exist

  - by Tim Visher

  I have tho following clean function in my build script and I'd like to know how I can improve it. <target name="clean" description="Clean output directories."> <!-- Must not fail on error because it fails if directories don't exist. Is there really no better way to do this? --> <delete includeEmptyDirs="true" failonerror="false"> <fileset dir="${main.build.directory}" /> <fileset dir="dist" /> <fileset dir="${documentation.build.directory}" /> <fileset dir="/build-testing" /> </delete> </target> Specifically regarding my comment, I'm unhappy with the fact that I can't run this on a fresh box because the directory structure hasn't been set up yet by the other targets. We run the build in such a way that it entirely recreates the structures necessary for testing and deployment every time to avoid stale class files and such. With the way that delete currently is set up, a failure to delete a file does not fail the build and I'd like it to. I don't want it to fail the build if the file doesn't exist though. If it doesn't exist then what I'm asking it to do has already happened. Thoughts?

• Full Text Index type column is empty

  - by RemotecUk

  I am trying to create an index on a VarBinary(max) field in my SQL Server 2008 database. The steps I am taking are as follows: Table: dbo.Records Right click on table and select "Full Text Index" Then select "Define Index..." I choose the primary key which is the PK of my table (field name Id, type UniqueIndentifier). I then get the screen with the options Available Columns, Language for Word Breaker and Type Column I select my VarBinary(max) field called Chart as the Available Column by ticking the box. I select "English" as the Language for Word Breaker field. Then... I try to select the Type Column but there are no entries in here. I cannot proceed by clicking "Next" until this column is populated. Why are there no entries in this column for selection and what should be in there? Note 1: The VarBinary(max) field is linked to a file group if that makes any difference. Note 2: Also noticed that in the table designer I cannot set the full text option on that same field to "Yes" - its permanently stuck on "No". Thanks.

• Solr associations

  - by Tom

  Hi all, The last couple of days we are thinking of using Solr as our search engine of choice. Most of the features we need are out of the box or can be easily configured. There is however one feature that we absolutely need that seems to be well hidden (or missing) in Solr. I'll try to explain with an example. We have lots of documents that are actually businesses: <document> <name>Apache</name> <cat>1</cat> ... </document> <document> <name>McDonalds</name> <cat>2</cat> ... </document> In addition we have another xml file with all the categories and synonyms: <cat id=1> <name>software</name> <synonym>IT<synonym> </cat> <cat id=2> <name>fast food</name> <synonym>restaurant<synonym> </cat> We want to associate both businesses and categories so we can search using the name and/or synonyms of the category. But we do not want to merge these files at indexing time because we should update the categories (adding.remioving synonyms...) without indexing all the businesses again. Is there anything in Solr that does this kind of associations or do we need to develop some specific pieces? All feedback and suggestions are welcome. Thanks in advance, Tom

• Why does the Chrome spacing work in one JS file and not the other?

  - by Matrym

  If you highlight and copy the text in the first paragraph on this page, then paste it into a rich text editor (dreamweaver or gmail in rich text mode), you will see that some of the text is automagically linked. Basically, it works: http://seox.org/link-building-pro.html -- http://seox.org/lbp/old-pretty.js I'm trying to build a second version, but somewhere along the way I broke it. If you go along with the same process on this new url, spacing before and after the link are removed in Chrome: http://seox.org/test.html -- http://seox.org/lbp/lb-core.js Why does the spacing work correctly in the first one, but not in the second? More importantly, how do I fix the second one so that it doesn't bug out? I asked a variation of this question before, and got a helpful and interesting answer, but hopefully I've asked the question with full detail this time around. Thanks in advance for your time! Edit: I've added a bounty to this post, and would greatly appreciate precise instructions on how to fix the bug (rather than general suggestions. To better illustrate the bug, I've copied the gray box (from the second page) below.

• How to install DBD::mysql on OS X server?

  - by Zoran Simic

  Trying to install DBD::mysql on OS X Server 10.6 (mac mini server). But I'm missing the mysql headers apparently. Since mysql is already part of OS X Server 10.6, I would like to NOT install anything else (no fink or darwin ports installs), just whatever's needed to get DBD::mysql installed and working. Do you know how I could do that? Do I have to install the headers somewhere? And if so, where? (again: I don't want to install another version of mysql on the box, want to use the version it came with). Is there a way to install DBD::mysql without compiling any C files? This is the error I get (the actual error is much longer, but these are the most meaningful bits, this is the first error reported). Checking if your kit is complete...

• Does HttpListener work well on Mono?

  - by billpg

  Hi everyone. I'm looking to write a small web service to run on a small Linux box. I prefer to code in C#, so I'm looking to use Mono. I don't want the overhead of running a full web server or Mono's version of ASP.NET. I'm thinking of having a single process with a thread dealing with each client connection. Shared memory between threads instead of a database. I've read a little on Microsoft's version of HttpListener and how it works with the Http.sys driver. Alas, Mono's documentation on this class is just the automated class interface with no discussion of how it works under the hood. (Linux doesn't have Http.sys, so I imagine it's implemented substantially differently.) Could anyone point me towards some resources discussing this module please? Many thanks, Bill, billpg.com (A little background to my question for the interested.) Some time ago, I asked this question, interested in keeping a long conversation open with lots of back-and-forth. I had settled on designing my own ad-hoc protocol, but people I spoke to really wanted a REST interface, even at the cost of the "Okay, send your command now" signal. So, I wondered about running ASP.NET on a Linux/Mono server, but stumbled upon HttpListener. This seemed ideal, as each "conversation" could run in a separate thread. The thread that calls HttpListener in a loop can look for which thread each incomming connection is for and pass the reference to that thread. The alternative for an ASP.NET driven service, would be to have the ASPX code pick up the state from a database, and write back the new state when it finishes. Yes, it would work, but that's a lot of overhead.

• RFC: Whitespace's Assembly Mnemonics

  - by Noctis Skytower

  Request For Comment regarding Whitespace's Assembly Mnemonics What follows in a first generation attempt at creating mnemonics for a whitespace assembly language. STACK ===== push number copy copy number swap away away number MATH ==== add sub mul div mod HEAP ==== set get FLOW ==== part label call label goto label zero label less label back exit I/O === ochr oint ichr iint In the interest of making improvements to this small and simple instruction set, this is a second attempt. hold N Push the number onto the stack copy Duplicate the top item on the stack copy N Copy the nth item on the stack (given by the argument) onto the top of the stack swap Swap the top two items on the stack drop Discard the top item on the stack drop N Slide n items off the stack, keeping the top item add Addition sub Subtraction mul Multiplication div Integer Division mod Modulo save Store load Retrieve L: Mark a location in the program call L Call a subroutine goto L Jump unconditionally to a label if=0 L Jump to a label if the top of the stack is zero if<0 L Jump to a label if the top of the stack is negative return End a subroutine and transfer control back to the caller exit End the program print chr Output the character at the top of the stack print int Output the number at the top of the stack input chr Read a character and place it in the location given by the top of the stack input int Read a number and place it in the location given by the top of the stack What is the general consensus on the following revised list for Whitespace's assembly instructions? They definitely come from thinking outside of the box and trying to come up with a better mnemonic set than last time. When the previous python interpreter was written, it was completed over two contiguous, rushed evenings. This rewrite deserves significantly more time now that it is the summer. Of course, the next version of Whitespace (0.4) may have its instructions revised even more, but this is just a redesign of what originally was done in a few hours. Hopefully, the instructions make more sense to those new to programming jargon.

• JQuery Autocomplete Where the Results are Links

• How do you reenable a validation control w/o it simultaneously performing an immediate validation?

  - by Velika2

  When I called this function to enable a validator from client javascript: `ValidatorEnable(document.getElementById('<%=valPassportOtherText.ClientID%>'), true); //enable` validation control the required validation control immediately performed it validation, found the value in the associated text box blank and set focus to the textbox (because SetFocusOnError was set to true). As a result, the side effect was that focus was shifted to the control that was associated with the Validation control, i teh example, txtSpecifyOccupation. <asp:TextBox ID="txtSpecifyOccupation" runat="server" AutoCompleteType="Disabled" CssClass="DefaultTextBox DefaultWidth" MaxLength="24" Rows="2"></asp:TextBox> <asp:RequiredFieldValidator ID="valSpecifyOccupation" runat="server" ControlToValidate="txtSpecifyOccupation" ErrorMessage="1.14b Please specify your &lt;b&gt;Occupation&lt;/b&gt;" SetFocusOnError="True">&nbsp;Required</asp:RequiredFieldValidator> Perhaps there is a way to enable the (required) validator without having it simultaneously perform the validation (at least until the user has tabbed off of it?) I'd like validation of the txtSpecifyOccupation textbox to occur only on a Page submit or when the user has tabbed of the required txtSpecifyoccupation textbox. How can I achieve this?

• Pinyin Character entry on a touchscreen keyboard

  - by mmr

  The app I'm developing requires that it be deployed in China, which means that it needs to have Pinyin and Chinese character handling. I'm told that the way that our customers handle character entry is like so: Enter in the pinyin character, like 'zhang' As they enter the characters, a list of possible Chinese (Mandarin?) characters are presented to the user, like: The user will then select '1' to enter the family name that is roughly translated to 'zhang' How can I hook such programs (I believe one is called 'mspy.exe', from Microsoft, which I'm lead to believe comes with Microsoft versions of XP) into a WPF text box? Right now, the user can enter text either by using their keyboard or by using an on-screen keyboard, so I will probably need to capture the event of a keypress from either source and feed it to some OS event or to MSPY.exe or some similar program. Or is there some other way to enter pinyin and have it converted to Mandarin? Is there a program other than MSPY I should look at? EDIT: For those of you who think that this should 'just work', it does not. Chinese character entry will work just fine if entering text into notepad or the start-run menu or whatever, but it will not work in WPF. That's the key to this question: how do I enable WPF entry? There's the Google Pinyin and Sogou pinyin, but the websites are in Mandarin or Chinese or something similar and I don't read the language.

• F# and statically checked union cases

  - by Johan Jonasson

  Soon me and my brother-in-arms Joel will release version 0.9 of Wing Beats. It's an internal DSL written in F#. With it you can generate XHTML. One of the sources of inspiration have been the XHTML.M module of the Ocsigen framework. I'm not used to the OCaml syntax, but I do understand XHTML.M somehow statically check if attributes and children of an element are of valid types. We have not been able to statically check the same thing in F#, and now I wonder if someone have any idea of how to do it? My first naive approach was to represent each element type in XHTML as a union case. But unfortunately you cannot statically restrict which cases are valid as parameter values, as in XHTML.M. Then I tried to use interfaces (each element type implements an interface for each valid parent) and type constraints, but I didn't manage to make it work without the use of explicit casting in a way that made the solution cumbersome to use. And it didn't feel like an elegant solution anyway. Today I've been looking at Code Contracts, but it seems to be incompatible with F# Interactive. When I hit alt + enter it freezes. Just to make my question clearer. Here is a super simple artificial example of the same problem: type Letter = | Vowel of string | Consonant of string let writeVowel = function | Vowel str -> sprintf "%s is a vowel" str I want writeVowel to only accept Vowels statically, and not as above, check it at runtime. How can we accomplish this? Does anyone have any idea? There must be a clever way of doing it. If not with union cases, maybe with interfaces? I've struggled with this, but am trapped in the box and can't think outside of it.
