  • PHP script works fine until I send a parameter from HTTPService in Flash Builder 4?

    - by ben
    I'm using a PHP script to read an RSS feed in my Flex 4 app. The script works when I put the url of the feed in the actual script, but I can't get it to work when I try to send the URL as a parameter from a HTTPService in Flex. Can anyone tell me what I'm doing wrong? Here is the HTTPService from Flex 4 that I'm using: <mx:HTTPService url="http://talk.6te.net/proxy.php" id="proxyService" method="POST" result="rssResult()" fault="rssFault()"> <mx:request> <url> http://feeds.feedburner.com/nah_right </url> </mx:request> </mx:HTTPService> This is the script that works: <?php $ch = curl_init(); $timeout = 30; $userAgent = $_SERVER['HTTP_USER_AGENT']; curl_setopt($ch, CURLOPT_URL, "http://feeds.feedburner.com/nah_right"); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); curl_setopt($ch, CURLOPT_USERAGENT, $userAgent); $response = curl_exec($ch); if (curl_errno($ch)) { echo curl_error($ch); } else { curl_close($ch); echo $response; } ?> But this is what I actually want to use, but it doesn't work: <?php $ch = curl_init(); $timeout = 30; $userAgent = $_SERVER['HTTP_USER_AGENT']; curl_setopt($ch, CURLOPT_URL, $_REQUEST['url']); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); curl_setopt($ch, CURLOPT_USERAGENT, $userAgent); $response = curl_exec($ch); if (curl_errno($ch)) { echo curl_error($ch); } else { curl_close($ch); echo $response; } ?> Here is the request and response output of the HTTPService from the network monitor in Flash Builder 4 (using the PHP script that doesn't work): Request: POST /proxy.php HTTP/1.1 Host: talk.6te.net User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Content-type: application/x-www-form-urlencoded Content-length: 97 url=%0A%09%09%09%09%09http%3A%2F%2Ffeeds%2Efeedburner%2Ecom%2Fnah%5Fright%0A%20%20%20%20%09%09%09 Response: HTTP/1.1 200 OK Date: Mon, 10 May 2010 03:23:27 GMT Server: Apache X-Powered-By: PHP/5.2.13 Content-Length: 15 Content-Type: text/html <url> malformed I've tried putting the URL in " " in the HTTPService, but that didn't do anything.

  • ASP.NET MVC, Webform hybrid

    - by Greg Ogle
    We (me and my team) have a ASP.NET MVC application and we are integrating a page or two that are Web Forms. We are trying to reuse the Master Page from our MVC part of the app in the WebForms part. We have found a way of rendering an MVC partial view in web forms, which works great, until we try and do a postback, which is the reason for using a WebForm. The Error: Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster. The Code to render the partial view from a WebForm (credited to "How to include a partial view inside a webform"): public static class WebFormMVCUtil { public static void RenderPartial(string partialName, object model) { //get a wrapper for the legacy WebForm context var httpCtx = new HttpContextWrapper(System.Web.HttpContext.Current); //create a mock route that points to the empty controller var rt = new RouteData(); rt.Values.Add("controller", "WebFormController"); //create a controller context for the route and http context var ctx = new ControllerContext( new RequestContext(httpCtx, rt), new WebFormController()); //find the partial view using the viewengine var view = ViewEngines.Engines.FindPartialView(ctx, partialName).View; //create a view context and assign the model var vctx = new ViewContext(ctx, view, new ViewDataDictionary { Model = model }, new TempDataDictionary()); //ERROR OCCURS ON THIS LINE view.Render(vctx, System.Web.HttpContext.Current.Response.Output); } } My only experience with this error is in context of a web farm, which is not the case. Also, I understand that the machine key is used for decrypting the ViewState. Any information on how to diagnose this issue would be appreciated. A Work-around: So far the work-around is to move the header content to a PartialView, then use an AJAX call to call a page with just the Partial View from the WebForms, and then using the PartialView directly on the MVC Views. Also, we are still able to share non-tech-specific parts of the Master Page, i.e. anything that is not MVC specific. Still yet, this is not an ideal solution, a server-side solution is still desired. Also, this solutino has issues when working with controls that have more sophisticated controls, using JavaScript, particularly dynamically generated script as used by 3rd party controls.

  • Calculating multiple column average in SQLite3

    - by Benjamin Oakes
    I need to average some values in a row-wise fashion, rather than a column-wise fashion. (If I were doing a column-wise average, I could just use avg()). My specific application of this requires me ignore NULLs in averaging. It's pretty straightforward logic, but seems awfully difficult to do in SQL. Is there an elegant way of doing my calculation? I'm using SQLite3, for what it's worth. Details If you need more details, here's an illustration: I have a a table with a survey: | q1 | q2 | q3 | ... | q144 | |----|-------|-------|-----|------| | 1 | 3 | 7 | ... | 2 | | 4 | 2 | NULL | ... | 1 | | 5 | NULL | 2 | ... | 3 | (Those are just some example values and simple column names. The valid values are 1 through 7 and NULL.) I need to calculate some averages like so: q7 + q33 + q38 + q40 + ... + q119 / 11 as domain_score_1 q10 + q11 + q34 + q35 + ... + q140 / 13 as domain_score_2 ... q2 + q5 + q13 + q25 + ... + q122 / 12 as domain_score_14 ...but i need to pull out the nulls and average based on the non-nulls. So, for domain_score_1 (which has 11 items), I would need to do: Input: 3, 5, NULL, 7, 2, NULL, 3, 1, 5, NULL, 1 (3 + 5 + 7 + 2 + 3 + 1 + 5 + 1) / (11 - 3) 27 / 8 3.375 A simple algorithm I'm considering is: Input: 3, 5, NULL, 7, 2, NULL, 3, 1, 5, NULL, 1 Coalesce each value to 0 if NULL: 3, 5, 0, 7, 2, 0, 3, 1, 5, 0, 1 Sum: 27 Get the number of non-zeros by converting values 0 to 1 and sum: 3, 5, 0, 7, 2, 0, 3, 1, 5, 0, 1 1, 1, 0, 1, 1, 0, 1, 1, 1, 0, 1 8 Divide those two numbers 27 / 8 3.375 But that seems like a lot more programming than this should take. Is there an elegant way of doing this that I'm not aware of? Update: Unless I'm misunderstanding something, avg() won't work for this. Example of what I would want to do: select avg(q7, q33, q38, ..., q119) from survey; Output: SQL error near line 3: wrong number of arguments to function avg()

  • Conceal packet loss in PCM stream

    - by ZeroDefect
    I am looking to use 'Packet Loss Concealment' to conceal lost PCM frames in an audio stream. Unfortunately, I cannot find a library that is accessible without all the licensing restrictions and code bloat (...up for some suggestions though). I have located some GPL code written by Steve Underwood for the Asterisk project which implements PLC. There are several limitations; although, as Steve suggests in his code, his algorithm can be applied to different streams with a bit of work. Currently, the code works with 8kHz 16-bit signed mono streams. Variations of the code can be found through a simple search of Google Code Search. My hope is that I can adapt the code to work with other streams. Initially, the goal is to adjust the algorithm for 8+ kHz, 16-bit signed, multichannel audio (all in a C++ environment). Eventually, I'm looking to make the code available under the GPL license in hopes that it could be of benefit to others... Attached is the code below with my efforts. The code includes a main function that will "drop" a number of frames with a given probability. Unfortunately, the code does not quite work as expected. I'm receiving EXC_BAD_ACCESS when running in gdb, but I don't get a trace from gdb when using 'bt' command. Clearly, I'm trampimg on memory some where but not sure exactly where. When I comment out the *amdf_pitch* function, the code runs without crashing... int main (int argc, char *argv[]) { std::ifstream fin("C:\\cc32kHz.pcm"); if(!fin.is_open()) { std::cout << "Failed to open input file" << std::endl; return 1; } std::ofstream fout_repaired("C:\\cc32kHz_repaired.pcm"); if(!fout_repaired.is_open()) { std::cout << "Failed to open output repaired file" << std::endl; return 1; } std::ofstream fout_lossy("C:\\cc32kHz_lossy.pcm"); if(!fout_lossy.is_open()) { std::cout << "Failed to open output repaired file" << std::endl; return 1; } audio::PcmConcealer Concealer; Concealer.Init(1, 16, 32000); //Generate random numbers; srand( time(NULL) ); int value = 0; int probability = 5; while(!fin.eof()) { char arr[2]; fin.read(arr, 2); //Generate's random number; value = rand() % 100 + 1; if(value <= probability) { char blank[2] = {0x00, 0x00}; fout_lossy.write(blank, 2); //Fill in data; Concealer.Fill((int16_t *)blank, 1); fout_repaired.write(blank, 2); } else { //Write data to file; fout_repaired.write(arr, 2); fout_lossy.write(arr, 2); Concealer.Receive((int16_t *)arr, 1); } } fin.close(); fout_repaired.close(); fout_lossy.close(); return 0; } PcmConcealer.hpp /* * Code adapted from Steve Underwood of the Asterisk Project. This code inherits * the same licensing restrictions as the Asterisk Project. */ #ifndef __PCMCONCEALER_HPP__ #define __PCMCONCEALER_HPP__ /** 1. What does it do? The packet loss concealment module provides a suitable synthetic fill-in signal, to minimise the audible effect of lost packets in VoIP applications. It is not tied to any particular codec, and could be used with almost any codec which does not specify its own procedure for packet loss concealment. Where a codec specific concealment procedure exists, the algorithm is usually built around knowledge of the characteristics of the particular codec. It will, therefore, generally give better results for that particular codec than this generic concealer will. 2. How does it work? While good packets are being received, the plc_rx() routine keeps a record of the trailing section of the known speech signal. If a packet is missed, plc_fillin() is called to produce a synthetic replacement for the real speech signal. The average mean difference function (AMDF) is applied to the last known good signal, to determine its effective pitch. Based on this, the last pitch period of signal is saved. Essentially, this cycle of speech will be repeated over and over until the real speech resumes. However, several refinements are needed to obtain smooth pleasant sounding results. - The two ends of the stored cycle of speech will not always fit together smoothly. This can cause roughness, or even clicks, at the joins between cycles. To soften this, the 1/4 pitch period of real speech preceeding the cycle to be repeated is blended with the last 1/4 pitch period of the cycle to be repeated, using an overlap-add (OLA) technique (i.e. in total, the last 5/4 pitch periods of real speech are used). - The start of the synthetic speech will not always fit together smoothly with the tail of real speech passed on before the erasure was identified. Ideally, we would like to modify the last 1/4 pitch period of the real speech, to blend it into the synthetic speech. However, it is too late for that. We could have delayed the real speech a little, but that would require more buffer manipulation, and hurt the efficiency of the no-lost-packets case (which we hope is the dominant case). Instead we use a degenerate form of OLA to modify the start of the synthetic data. The last 1/4 pitch period of real speech is time reversed, and OLA is used to blend it with the first 1/4 pitch period of synthetic speech. The result seems quite acceptable. - As we progress into the erasure, the chances of the synthetic signal being anything like correct steadily fall. Therefore, the volume of the synthesized signal is made to decay linearly, such that after 50ms of missing audio it is reduced to silence. - When real speech resumes, an extra 1/4 pitch period of sythetic speech is blended with the start of the real speech. If the erasure is small, this smoothes the transition. If the erasure is long, and the synthetic signal has faded to zero, the blending softens the start up of the real signal, avoiding a kind of "click" or "pop" effect that might occur with a sudden onset. 3. How do I use it? Before audio is processed, call plc_init() to create an instance of the packet loss concealer. For each received audio packet that is acceptable (i.e. not including those being dropped for being too late) call plc_rx() to record the content of the packet. Note this may modify the packet a little after a period of packet loss, to blend real synthetic data smoothly. When a real packet is not available in time, call plc_fillin() to create a sythetic substitute. That's it! */ /*!

  • DataContractSerializer and XSLT not Serializing Class Properties

    - by Russ Clark
    I've written a simple Employee class that I'm trying to serialize to an XDocument and then use XSLT to transform the document to a page that displays both the properties (Name and ID) from the Employee class, and an html form with 2 radio buttons (Approve and Reject) and a submit button. Here is the Employee class: [Serializable, DataContract(Namespace="XSLT_MVC.Controllers/")] public class Employee { [DataMember] public string Name { get; set; } [DataMember] public int ID { get; set; } public Employee() { } public Employee(string name, int id) { Name = name; ID = id; } public XDocument GetDoc() { XDocument doc = new XDocument(); var serializer = new DataContractSerializer(typeof(Employee)); using (var writer = doc.CreateWriter()) { serializer.WriteObject(writer, this); writer.Close(); } return doc; } } And here is the XSLT file: <?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" > <xsl:output method="html" indent="yes"/> <xsl:template match="/"> <html> <body> <xsl:value-of select="Employee/Name"/> <br /> <xsl:value-of select="Employee/ID"/> <br /> <form method="post" action="/Home/ProcessRequest?id={Employee/ID}"> <input id="Action" name="Action" type="radio" value="Approved"></input> Approved <br /> <input id="Action" name="Action" type="radio" value="Rejected"></input> Rejected <br /> <input type="submit" value="Submit"></input> </form> </body> </html> </xsl:template> </xsl:stylesheet> When I run this, all I get is the html form with the 2 radio buttons and the submit button, but not the properties from the Employee class. I saw a separate StackOverflow post that said I need to change the <xsl:template match="/"> to match on the namespace of my Employee class like this: <xsl:template match="/XSLT_MVC.Controllers"> but when I do that, now all I get are the Employee properties, and not the html form with the 2 radio buttons and the submit button. Does anyone know what needs to be done so that my transform will select and display both the Employee properties and the html form?

  • How to produce precisely-timed tone and silence in C#

    - by Bob Denny
    I have a C# project that plays Morse code for RSS feeds. I write it using Managed DirectX, only to discover that Managed DirectX is old and deprecated. The task I have is to play pure sine wave bursts interspersed with silence periods (the code) which are precisely timed as to their duration. I need to be able to call a function which plays a pure tone for so many milliseconds, then Thread.Sleep() then play another, etc. At its fastest, the tones and spaces can be as short as 40ms. It's working quite well in Managed DirectX. To get the precisely timed tone I create 1 sec. of sine wave into a secondary buffer, then to play a tone of a certain duration I seek forward to within x milliseconds of the end of the buffer then play. I've tried System.Media.SoundPlayer. It's a loser because you have to Play(), Sleep(), then Stop() for arbitrary tone lengths. The result is a tone that is too long, variable by CPU load. It takes an indeterminate amount of time to actually stop the tone. I then embarked on a lengthy attempt to use NAudio 1.3. I ended up with a memory resident stream providing the tone data, and again seeking forward leaving the desired length of tone remaining in the stream, then playing. This worked OK on the DirectSoundOut class for a while (see below) but the WaveOut class quickly dies with an internal assert saying that buffers are still on the queue despite PlayerStopped = true. This is odd since I play to the end then put a wait of the same duration between the end of the tone and the start of the next. You'd think that 80ms after starting Play of a 40 ms tone that it wouldn't have buffers on the queue. DirectSoundOut works well for a while, but its problem is that for every tone burst Play() it spins off a separate thread. Eventually (5 min or so) it just stops working. You can see thread after thread after thread exiting in the Output window while running the project in VS2008 IDE. I don't create new objects during playing, I just Seek() the tone stream then call Play() over and over, so I don't think it's a problem with orphaned buffers/whatever piling up till it's choked. I'm out of patience on this one, so I'm asking in the hopes that someone here has faced a similar requirement and can steer me in a direction with a likely solution. Thanks in advance...

  • EJB client can't find a DataSource that tests successfully in WebLogic admin console

    - by suszterpatt
    Disclaimer: I'm completely new to JEE/EJB and all that, so bear with me. I have a simple EJB that I can successfully deploy using JDeveloper 11g's integrated WebLogic server and a remote database connection (JDBC). I have a DataSource named "PGY2" defined in WebLogic, and I can test it successfully from the admin console. Here's the code of the client I'm trying to test it with (generated entirely by JDev except for the three method calls on adminManager): public class AdminManagerClient { public static void main(String [] args) { try { final Context context = getInitialContext(); AdminManager adminManager = (AdminManager)context.lookup("Uran-AdminManager#hu.elte.pgy2.BACNAAI.UranEJB.AdminManager"); adminManager.addAdmin("root", "root", "Kovács Isten"); adminManager.addStudent("BACNAAI", "matt", "B Cs", 2005); adminManager.addTeacher("SIPKABT", "patt", "S P", "numanal", "Dr."); } catch (Exception ex) { ex.printStackTrace(); } } private static Context getInitialContext() throws NamingException { Hashtable env = new Hashtable(); // WebLogic Server 10.x connection details env.put( Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory" ); env.put(Context.PROVIDER_URL, "t3://127.0.0.1:7101"); return new InitialContext( env ); } } But when I try to run this, I get the following error on the line with adminManager.addAdmin (that is, after the lookup): javax.ejb.EJBException: EJB Exception: ; nested exception is: Exception [EclipseLink-4002] (Eclipse Persistence Services - 1.0.2 (Build 20081024)): org.eclipse.persistence.exceptions.DatabaseException Internal Exception: java.sql.SQLException: Internal error: Cannot obtain XAConnection Creation of XAConnection for pool PGY2 failed after waitSecs:30 : java.sql.SQLException: Data Source PGY2 does not exist. Why can't the client find the data source, and how do I make it find it? EDIT: I took a closer look at WebLogic's output during deployment, and I found this. I have no idea what it means, but it may be relevant: <2010.05.20. 0:50:43 CEST> <Error> <Deployer> <BEA-149231> <Unable to set the activation state to true for the application 'PGY2'. weblogic.application.ModuleException: at weblogic.jdbc.module.JDBCModule.activate(JDBCModule.java:349) at weblogic.application.internal.flow.ModuleListenerInvoker.activate(ModuleListenerInvoker.java:107) at weblogic.application.internal.flow.DeploymentCallbackFlow$2.next(DeploymentCallbackFlow.java:411) at weblogic.application.utils.StateMachineDriver.nextState(StateMachineDriver.java:37) at weblogic.application.internal.flow.DeploymentCallbackFlow.activate(DeploymentCallbackFlow.java:74) Truncated. see log file for complete stacktrace weblogic.common.ResourceException: is already bound at weblogic.jdbc.common.internal.RmiDataSource.start(RmiDataSource.java:387) at weblogic.jdbc.common.internal.DataSourceManager.createAndStartDataSource(DataSourceManager.java:136) at weblogic.jdbc.common.internal.DataSourceManager.createAndStartDataSource(DataSourceManager.java:97) at weblogic.jdbc.module.JDBCModule.activate(JDBCModule.java:346) at weblogic.application.internal.flow.ModuleListenerInvoker.activate(ModuleListenerInvoker.java:107) Truncated. see log file for complete stacktrace >

  • Difficulties getting GraphViz working as a library in C++

    - by DistortedLojik
    Am working on a program that will allow a graph of nodes to be displayed and then updated visually as the nodes themselves are updated.

  • Faster Matrix Multiplication in C#

    - by Kyle Lahnakoski
    I have as small c# project that involves matrices. I am processing large amounts of data by splitting it into n-length chunks, treating the chucks as vectors, and multiplying by a Vandermonde** matrix. The problem is, depending on the conditions, the size of the chucks and corresponding Vandermonde** matrix can vary. I have a general solution which is easy to read, but way too slow: public byte[] addBlockRedundancy(byte[] data) { if (data.Length!=numGood) D.error("Expecting data to be just "+numGood+" bytes long"); aMatrix d=aMatrix.newColumnMatrix(this.mod, data); var r=vandermonde.multiplyBy(d); return r.ToByteArray(); }//method This can process about 1/4 megabytes per second on my i5 U470 @ 1.33GHz. I can make this faster by manually inlining the matrix multiplication: int o=0; int d=0; for (d=0; d<data.Length-numGood; d+=numGood) { for (int r=0; r<numGood+numRedundant; r++) { Byte value=0; for (int c=0; c<numGood; c++) { value=mod.Add(value, mod.Multiply(vandermonde.get(r, c), data[d+c])); }//for output[r][o]=value; }//for o++; }//for This can process about 1 meg a second. (Please note the "mod" is performing operations over GF(2^8) modulo my favorite irreducible polynomial.) I know this can get a lot faster: After all, the Vandermonde** matrix is mostly zeros. I should be able to make a routine, or find a routine, that can take my matrix and return a optimized method which will effectively multiply vectors by the given matrix, but faster. Then, when I give this routine a 5x5 Vandermonde matrix (the identity matrix), there is simply no arithmetic to perform, and the original data is just copied. ** Please note: What I use the term "Vandermonde", I actually mean an Identity matrix with some number of rows from the Vandermonde matrix appended (see comments). This matrix is wonderful because of all the zeros, and because if you remove enough rows (of your choosing) to make it square, it is an invertible matrix. And, of course, I would like to use this same routine to convert any one of those inverted matrices into an optimized series of instructions. How can I make this matrix multiplication faster? Thanks! (edited to correct my mistake with Vandermonde matrix)

  • CSS text-decoration rule ignored

    - by Ferdy
    I have found similar questions to mine but none of the suggestions seems to apply to my situation, so here goes... I have a webpage with a buch of images on them. Each image has a title which in markup is between h2 tags. The title is a link, so the resulting markup is like this: <ul class="imagelist"> <li> <a href=""><h2>Title 1</h2></a> <a href=""><img src="" /></a> </li> <li> Image 2, etc... </li> </ul> All I want is for the title links to not be underlined. I tried to address this like this: .imagelist li a h2 { color:#333; text-decoration:none; } It completely ignores the text-decoration rule, yet respects the color rule. From other questions I learned that this could be because a child element cannot overrule the text-decoration of any of its parents. So, I went looking for the parent elements to see if any explicit text-decoration rules are applied. I found none. This is driving me crazy, any help? For the sake of completeness, here is the Firebug CSS output, which shows the full inheritance and such. Probably more than you want, but I cannot see anything conflicting here. .imagelist li a h2 { color:#333333; text-decoration:none; } main.css (line 417) h2 { font-size:14px; } main.css (line 40) h1, h2, h3, h4, h5, h6 { display:block; font-weight:bold; margin-bottom:10px; } main.css (line 38) h1, h2, h3, h4, h5, h6 { font-size:100%; font-weight:normal; } reset-min.css (line 7) body, div, dl, dt, dd, ul, ol, li, h1, h2, h3, h4, h5, h6, pre, code, form, fieldset, legend, input, textarea, p, blockquote, th, td { margin:0; padding:0; } reset-min.css (line 7) Inherited froma /apps/ju...mage/745 a { color:#0063E2; } main.css (line 55) Inherited fromli .imagelist li { list-style-type:none; } main.css (line 411) li { list-style:none outside none; } reset-min.css (line 7) Inherited fromul.imagelist .imagelist { border-collapse:collapse; font-size:9px; } main.css (line 410) Inherited frombody body, form { color:#333333; font:12px arial,helvetica,clean,sans-serif; } main.css (line 36) Inherited fromhtml html { color:#000000;

  • Can I Number a GroupTemplate or ItemTemplate?

    - by Atomiton
    I would like to use a GroupTemplate to separate a list of items into groups. However, I need each Group to be numbered sequentially so I can link to them and implement some JS paging. I'm binding to an IEnumerable Here's some pseudo code. I would like the output to look like this: <a href="#group1">Go to Group 1<a> <a href="#group2">Go to Group 2<a> <a href="#group3">Go to Group 3<a> <ul id="group1"> <li>Item</li> <li>Item</li> <li>Item</li> </ul> <ul id="group2"> <li>Item</li> <li>Item</li> <li>Item</li> </ul> <ul id="group3"> <li>Item</li> <li>Item</li> <li>Item</li> </ul> Is this easy to do in a ListView, using GroupTemplate and ItemTemplate? <asp:ListView ID="lv" runat="server" GroupPlaceholderID="groupPlaceholder"> <LayoutTemplate> <asp:PlaceHolder ID="groupPlaceholder" runat="server"></asp:PlaceHolder> </LayoutTemplate> <GroupTemplate> <ul id="<!-- group-n goes here -->"> <asp:PlaceHolder ID="itemPlaceholder" runat="server"></asp:PlaceHolder> </ul> </GroupTemplate> <ItemTemplate> <li>Item</li> </ItemTemplate> </asp:ListView> I can get the number of groups to do the links at the top from the Datasource and basic math, but how do I get id="groupN" number into the template?

  • php if clause inside foreach not retrieving data correctly

    - by Mike
    Here's my issue: In my controller, I want to grab user input from a form. I then parse the input, and compare it to database values to ensure I'm grabbing the correct input. I simply want to match the user's answers to the question, grab the user ID, the question ID, and then determine if the answer applies to a multiple choice or checkbox question, or something else. I take those values and insert them into the answer table. Ignore the waiver stuff. I'll test that once I get the answers input correctly. // add answers and waiver consent records try { $answerArray = array(); $waiverArray = array(); // retrieve answers, waiver consents, and the question ID's from form object foreach ($formData as $key => $value) { $parts = explode("_", $key); if ($parts[0] == 'question') { array_push($answerArray, $value); } if ($parts[0] == 'waiverTitle') { array_push($waiverArray, $value); } } $questions = new Model_DbTable_Questions(); $questionResults = $questions->getQuestionResults($session->idEvent); foreach ( $questionResults as $qr ) { if ($qr ['questionType'] == 'multipleChoice' || $qr ['questionType'] == 'checkBox') { foreach ( $answerArray as $aa ) { $answerData = $answers->addAnswer ( $lastUserID, $qr ['idQuestion'], null, $aa ); echo count ( $answerData ) . ', ' . $qr ['questionType'] . ', ' . $aa . '<br />'; } } else { foreach ( $answerArray as $aa ) { $answerData = $answers->addAnswer ( $lastUserID, $qr ['idQuestion'], $aa, null ); echo count ( $answerData ) . ', ' . $qr ['questionType'] . ', ' . $aa . '<br />'; } } } } catch (Zend_Db_Statement_Exception $e) { $e->getMessage(); throw $e; } From my test data, I expect to get 2 records that match the multiple choice and checkbox criteria, and 1 record for text in the ELSE clause like this: 3, checkbox, 1 3, multipleChoice, 1 3, text, question_2 What I get is a 3x3 Cartesian product, 3 question elements each with the 3 possible answers like this output from the echo statements: 4, checkBox, 1 4, checkBox, 1 4, checkBox, question_2 4, multipleChoice, 1 4, multipleChoice, 1 4, multipleChoice, question_2 4, text, 1 4, text, 1 4, text, question_2 I've tried placing the IF clause inside the inner foreach, but I get the same results. I've been staring at this problem for way too long and cannot see what I'm doing wrong. Your kind assistance would be greatly appreciated. Please let me know if my request requires more clarification.

  • Lightbox image / link URL

    - by GSTAR
    Basically I have a slightly non-standard implementation of FancyBox. By default you have to include a link to the large version of the image so that the Lightbox can display it. However, in my implementation, the image link URLs point to a script rather than directly to the image file. So for example, instead of: <a href="mysite/images/myimage.jpg" rel="gallery"> I have: <a href="mysite/photos/view/abc123" rel="gallery"> The above URL points to a function: public function actionPhotos($view) { $photo=Photo::model()->find('name=:name', array(':name'=>$view)); if(!empty($photo)) { $this->renderPartial('_photo', array('photo'=>$photo, true)); } } The "$this-renderPartial()" bit simply calls a layout file which includes a standard HTML tag to output. Now when the user clicks on a thumbnail, the above function is called and the large image is displayed in the Lightbox. Now if the user right clicks on the thumbnail and selects "open in new tab/window" then the image is displayed in the browser as per normal, i.e. just the image. I want to change this so that it displays the image within a layout. In the above code I can include the following and put it in an IF statement: $this->render('photos', array('photo'=>$photo)); This will call the layout file "photos" which contains the layout to display the image in. I have a specific limitation for this - the image URL must remain the same, i.e. no additional GET variables in the URL. However if we can pass in a GET variable in the background then that is OK. I will most likely need to change my function above so that it calls a different file for this functionality. EDIT: To demonstrate exactly what I am trying to do, check out the following: http://www.starnow.co.uk/KimberleyMarren Go to the photos tab and hover over a thumbnail - note the URL. Click the thumbnail and it will open up in the Lightbox. Next right click on that same thumbnail and select "open in new tab/new window". You will notice that the image is now displayed in a layout. So that same URL is used for displaying the image in the Lightbox and on its own page. The way StarNow have done this is using some crazy long JavaScript functionality, which I'm not too keen on replicating.

  • Add rss xmlns namespace definition to a php simplexml document?

    - by talkingnews
    I'm trying to create an itunes-valid podcast feed using php5's simplexml: <?php $xml_string = <<<XML <?xml version="1.0" encoding="UTF-8"?> <channel> </channel> XML; $xml_generator = new SimpleXMLElement($xml_string); $tnsoundfile = $xml_generator->addChild('title', 'Main Title'); $tnsoundfile->addChild('itunes:author', "Author", ' '); $tnsoundfile->addChild('category', 'Audio Podcasts'); $tnsoundfile = $xml_generator->addChild('item'); $tnsoundfile->addChild('title', 'The track title'); $enclosure = $tnsoundfile->addChild('enclosure'); $enclosure->addAttribute('url', 'http://test.com'); $enclosure->addAttribute('length', 'filelength'); $enclosure->addAttribute('type', 'audio/mpeg'); $tnsoundfile->addChild('itunes:author', "Author", ' '); header("Content-Type: text/xml"); echo $xml_generator->asXML(); ?> It doesn't validate, because I've got to put the line: <rss xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd" version="2.0"> as per http://www.apple.com/itunes/podcasts/specs.html. So the output SHOULD be: <?xml version="1.0" encoding="UTF-8"?> <rss xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd" version="2.0"> <channel> etc. I've been over and over the manual and forums, just can't get it right. If I put, near the footer: header("Content-Type: text/xml"); echo '<rss xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd" version="2.0">'; echo $xml_generator->asXML(); ?> Then it sort of looks right in firefox and it doesn't complain about undefined namespaces anymore, but feedvalidator complains that line 1, column 77: XML parsing error: :1:77: xml declaration not at start of external entity [help] because the document now starts: <rss xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd" version="2.0"><?xml version="1.0" encoding="UTF-8"?> and not <?xml version="1.0" encoding="UTF-8"?><rss xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd" version="2.0"> Thank you in advance.

  • OSGI classcast exception on felix

    - by Nico
    Hi, i'm fairly new to osgi and am trying to get a functional proof of concept together. The setup is that my common api is created in a bundle creatively named common-api.jar with no bundle activator, but it exports all it's interfaces. the one of interest in this situation is DatabaseService.java. I then have a Second bundle called systemx-database-service. That implements the database service interface. this works fine as in the activator of the implementation bundle i test the connection to the database and select some arbitraty values. I also register the service i want to be available to the other bundle's like so: context.registerService(DatabaseService.class.getName(), new SystemDatabaseServiceImpl(context), new Properties()); The basic idea being when you look for a service reference for a Database service you'll get back the SystemDatabaseService implementation. When i do a inspect service the output it this: -> inspect s c 69 System Database Service (69) provides services: ---------------------------------------------- objectClass = za.co.xxx.xxx.common.api.DatabaseService service.id = 39 which would lead me to believe that if i do this in a test bundle: context.getService(context.getServiceReference(DatabaseService.class)); i should get back an instance of DatabaseService.class, but alas no such luck. it simply seems like it cannot find the service. stick with me here my story gets stranger. figuring there is no where to go but up i wrote this monstrosity: for (Bundle bundle : bundles) { if (bundle.getSymbolicName().equals("za.co.xxx.xxx.database-service")) { ServiceReference[] registeredServices = bundle.getRegisteredServices(); for (ServiceReference ref : registeredServices) { DatabaseService service = (DatabaseService) context.getService(ref); // use service here. } } } } now i can actually see the service reference, but i get this error java.lang.ClassCastException: za.co.xxx.xxx.database.service.impl.SystemDatabaseServiceImpl cannot be cast to za.co.xxx.xx.common.api.DatabaseService which is crazy since the implementation clearly implements the interface! Any help would be appreciated. Please keep in mind i'm very new at the osgi way of thinking so my whole approach here might be flawed. oh. if anyone wants the manifests i can post them. and i'm using the maven-bnd-plugin to build and executing on felix. thanks Nico

  • create text inside a rectangle using inkscape

    I've put some text inside a rectangle using inkscape so the tree is like <svg:rect><svg:text><svg:tspan>text.... The problem is, I can't see the text.

  • Need to add an array into another array at a specified key value

    - by sologhost
    Ok, I have an array like so, but it's not guaranteed to be laid out in this order all of the time... $array = array( 'sadness' => array( 'info' => 'some info', 'info2' => 'more info', 'value' => 'value', ), 'happiness' => array( 'info' => 'some info', 'info2' => 'more info', 'value' => 'the value', ), 'peace' => array( 'info' => 'some info', 'info2' => 'more info', 'value' => 'the value', ) ); Ok, and I'd like to throw in this array right after the happiness key is defined. I can't use the key of "peace" since it must go directly after happiness, and peace might not come after happiness as this array changes. So here's what I need to add after happiness... $another_array['love'] = array( 'info' => 'some info', 'info2' => 'more info', 'value' => 'the value of love' ); So the final output after it gets inputted directly after happiness should look like this: $array = array( 'sadness' => array( 'info' => 'some info', 'info2' => 'more info', 'value' => 'value', ), 'happiness' => array( 'info' => 'some info', 'info2' => 'more info', 'value' => 'the value', ), 'love' => array( 'info' => 'some info', 'info2' => 'more info', 'value' => 'the value of love', ), 'peace' => array( 'info' => 'some info', 'info2' => 'more info', 'value' => 'the value', ) ); Can someone please give me a hand with this. Using array_shift, array_pop, or array_merge doesn't help me at all, since these go at the beginning and at the end of the array. I need to place it directly after a KEY position within $array. Thanks :)

  • Rotation Matrix calculates by column not by row

    - by pinnacler
    I have a class called forest and a property called fixedPositions that stores 100 points (x,y) and they are stored 250x2 (rows x columns) in MatLab. When I select 'fixedPositions', I can click scatter and it will plot the points. Now, I want to rotate the plotted points and I have a rotation matrix that will allow me to do that. The below code should work: theta = obj.heading * pi/180; apparent = [cos(theta) -sin(theta) ; sin(theta) cos(theta)] * obj.fixedPositions; But it wont. I get this error. ??? Error using == mtimes Inner matrix dimensions must agree. Error in == landmarkslandmarks.get.apparentPositions at 22 apparent = [cos(theta) -sin(theta) ; sin(theta) cos(theta)] * obj.fixedPositions; When I alter forest.fixedPositions to store the variables 2x250 instead of 250x2, the above code will work, but it wont plot. I'm going to be plotting fixedPositions constantly in a simulation, so I'd prefer to leave it as it, and make the rotation work instead. Any ideas? Also, fixed positions, is the position of the xy points as if you were looking straight ahead. i.e. heading = 0. heading is set to 45, meaning I want to rotate points clockwise 45 degrees. Here is my code: classdef landmarks properties fixedPositions %# positions in a fixed coordinate system. [x, y] heading = 45; %# direction in which the robot is facing end properties (Dependent) apparentPositions end methods function obj = landmarks(numberOfTrees) %# randomly generates numberOfTrees amount of x,y coordinates and set %the array or matrix (not sure which) to fixedPositions obj.fixedPositions = 100 * rand([numberOfTrees,2]) .* sign(rand([numberOfTrees,2]) - 0.5); end function obj = set.apparentPositions(obj,~) theta = obj.heading * pi/180; [cos(theta) -sin(theta) ; sin(theta) cos(theta)] * obj.fixedPositions; end function apparent = get.apparentPositions(obj) %# rotate obj.positions using obj.facing to generate the output theta = obj.heading * pi/180; apparent = [cos(theta) -sin(theta) ; sin(theta) cos(theta)] * obj.fixedPositions; end end end P.S. If you change one line to this: obj.fixedPositions = 100 * rand([2,numberOfTrees]) .* sign(rand([2,numberOfTrees]) - 0.5); Everything will work fine... it just wont plot.

  • PHP Form POST to external URL with Redirect to another URL

    - by Marlon
    So, what I am trying to accomplish is have a self-posting PHP form, POST to an external page (using CURL) which in turn redirects to another page. Currently, what is happening is that once I click "Submit" on the form (in contact.php) it will POST to itself (as it is a self-posting form). The script then prepares the POST using CURL and performs the post. The external page does its processing and then, the external page is supposed to redirect back to another page, in a referring domain. However, what happens instead, is that it seems like the contact.php page loads the HTML from the page the external page redirected to, and then, the contact.php's HTML loads after that, ON THE SAME PAGE. The effect, is what looks like two separate pages rendered as one page. Naturally, I just want to perform the POST and have the browser render the page it is supposed to redirect to as specified by the external page. Here is the code I have so far: <?php if(isset($_POST['submit'])) { doCURLPost(); } function doCURLPost() { $emailid = "2, 4"; $hotel = $_POST['hotel']; //you will need to setup an array of fields to post with //then create the post string $data = array ( "recipient" => $emailid, "subject" => "Hotel Contact Form", "redirect" => "http://www.localhost.com/thanx.htm", "Will be staying in hotel: " => $_POST['hotel'], "Name" => $_POST['Name'], "Phone" => $_POST['Phone'], "Comments" => $_POST['Comments']); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, "http://www.externallink.com/external.aspx"); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); curl_setopt($ch, CURLOPT_HTTPHEADER, array("Referer: http://www.localhost.com/contact.php")); $output = curl_exec($ch); $info = curl_getinfo($ch); curl_close($ch); } ?>

  • problem with filtering the dropdownlist in scroll window

    - by Rahul
    Hi all, Problem with filtering Dropdown list. The scenario is : in scroll window there are two fields Document types and type id: Document type is Dropdown list: As per document type selection type id look should display the values. For ex. If I select quote type from document type and if I open type id look up it should display only quotation in the look window. It should work for all the values of document type drop down list values. Its working fine. The item in the document types are: Quote, Order, Invoice, Return, BackOrder. The problem is after saving the data when I am displaying the same record in scroll window, suppose after displaying document type is QUOTE and document id is QTOARD, and in this position I am changing the document type from dropdown QUOTE to ORDER at this time warning message should c ome this range entered is in valid. Because in database table there is no document QTOARD for ORDER type. The same should work for all the condition. The table name is SOP_ID_Setp and key is SOP Type and DocumentID. For that I have written the Stored procedure : create procedure DocTypeFilter @DocumentType as int, @DocumentID as varchar(30) as --declare --@documentype int, --@documentID varchar(30), select * from sop40200 where soptype=@DocumentType and docid=@DocumentID and I have called this SP in Dropdownlist change event. local long retcode; range clear table SOP_ID_SETP; clear field 'SOP Type' of table SOP_ID_SETP; clear field 'Document ID' of table SOP_ID_SETP; range start table SOP_ID_SETP; fill field 'SOP Type' of table SOP_ID_SETP; fill field 'Document ID' of table SOP_ID_SETP; range end table SOP_ID_SETP; if err()=OKAY then call DocTypeFilter,retcode,'Document Type' of window 'Is_Document Type Site_Scroll','Document ID' of window 'Is_Document Type Site_Scroll'; else warning "The range entered is invalid"; clear window 'Is_Document Type Site_Scroll'; fill window 'Is_Document Type Site_Scroll' table is_sop_site_line_temp; end if; Above code not giving the expected output any help pls.
