  • Check variable if explode-able in PHP

    - by ZaneDeFazio
    Not sure if there is a way to check a variable if it is explode-able or not... I have a database of city names some are one word cities and some are multiple word cities EX: Chicago, Los Angeles I keep getting an error when use "implode" when a city name is one word, so I tried using "count" and using an if statement... not having any luck $citi = explode(' ', $row['city']); $count = count($citi); if ($count > 1) { $city = implode('+', $citi); } else { $city = $citi; }

  • How to scan for available networks for Blackberry device from application?

    - by amsiddh
    Hi All, Is there any RIM API available which will help to get the list of available network service or only Wi-Fi networks for a device and set selected network access point for any network communications? Is it possible programmatically to disable the Mobile networks like GPRS, WAP, etc? For Ex: When a application is started it should scan for WiFi connections (even if there are no previous WiFi network access points are set on device) and list the available WiFi connection. Then user will select the appropriate WiFi connection to connect for any network communication. Outside the application any internet communication (like browser or any other application) should done through same selected WiFi connection. The scanning for WiFi and setting the connection is almost similar to Blackberry WiFi Setup. If anyone know how to implement this using available RIM API and let me know its possible or not. Please share if anyone have any code snippet related to this. I am looking for OS v4.5, 4.7, and 5.0. Thanks, siddh.

  • Does XAML design mode support more color than code view?

    - by Rahul Soni
    While working with SilverLight using Visual Studio 10, I found that in design mode XAML allows a wide plethora of colors. For ex. Lime is a valid color in XAML. <LinearGradientBrush EndPoint="1,0.5" StartPoint="0,0.5"> <GradientStop Color="Yellow" Offset="0" /> <GradientStop Color="Lime" Offset="1" /> While working with code though, I found that Lime and many other colors are missing... GradientStop blueGS = new GradientStop(); blueGS.Color = Colors.Lime; What am I missing? Both of these colors belong to System.Windows.Media.Colors.

  • jquery.validation - how to ignore default values when validating mandatory fields

    - by jack
    I am using jquery validation plugin to validate a registration form. Each text input field has instructions pre-filled as values in the input box ex: for a text-input box id='Name', the default value will be set to 'Enter Your Name'. I have pasted below sample code: <input type="text" id="Name" value="Enter Your Name" onfocus="if(this.value == 'Your Name'){this.value = '';}" type="text" class="required" onblur="if(this.value == ''){this.value='Your Name';}" size="25" /> What I need to know is how to specify in the validation rule such that the plugin throws a required field error if the input box contains either the default message or empty values. Help much appreciated.

  • spring mvc forward to jsp

    - by jerluc
    I currently have my web.xml configured to catch 404s and send them to my spring controller which will perform a search given the original URL request. The functionality is all there as far as the catch and search go, however the trouble begins to arise when I try to return a view. <bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver" p:order="1"> <property name="mediaTypes"> <map> <entry key="json" value="application/json" /> <entry key="jsp" value="text/html" /> </map> </property> <property name="defaultContentType" value="application/json" /> <property name="favorPathExtension" value="true" /> <property name="viewResolvers"> <list> <bean class="org.springframework.web.servlet.view.BeanNameViewResolver" /> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value="" /> </bean> </list> </property> <property name="defaultViews"> <list> <bean class="org.springframework.web.servlet.view.json.MappingJacksonJsonView" /> </list> </property> <property name="ignoreAcceptHeader" value="true" /> </bean> This is a snippet from my MVC config file. The problem lies in resolving the view's path to the /WEB-INF/jsp/ directory. Using a logger in my JBoss setup, I can see that when I test this search controller by going to a non-existent page, the following occurs: Server can't find the request Request is sent to 404 error page (in this case my search controller) Search controller performs search Search controller returns view name (for this illustration, we'll assume test.jsp is returned) Based off of server logger, I can see that org.springframework.web.servlet.view.JstlView is initialized once my search controller returns the view name (so I can assume it is being picked up correctly by the InternalResourceViewResolver) Server attempts to return content to browser resulting in a 404! A couple things confuse me about this: I'm not 100% sure why this isn't resolving when test.jsp clearly exists under the /WEB-INF/jsp/ directory. Even if there was some other problem, why would this result in a 404? Shouldn't a 404 error page that results in another 404 theoretically create an infinite loop? Thanks for any help or pointers! Controller class [incomplete]: @Controller public class SiteMapController { //-------------------------------------------------------------------------------------- @Autowired(required=true) private SearchService search; @Autowired(required=true) private CatalogService catalog; //-------------------------------------------------------------------------------------- @RequestMapping(value = "/sitemap", method = RequestMethod.GET) public String sitemap (HttpServletRequest request, HttpServletResponse response) { String forwardPath = ""; try { long startTime = System.nanoTime() / 1000000; String pathQuery = (String) request.getAttribute("javax.servlet.error.request_uri"); Scanner pathScanner = new Scanner(pathQuery).useDelimiter("\\/"); String context = pathScanner.next(); List<ProductLightDTO> results = new ArrayList<ProductLightDTO>(); StringBuilder query = new StringBuilder(); String currentValue; while (pathScanner.hasNext()) { currentValue = pathScanner.next().toLowerCase(); System.out.println(currentValue); if (query.length() > 0) query.append(" AND "); if (currentValue.contains("-")) { query.append("\""); query.append(currentValue.replace("-", " ")); query.append("\""); } else { query.append(currentValue + "*"); } } //results.addAll(this.doSearch(query.toString())); System.out.println("Request: " + pathQuery); System.out.println("Built Query:" + query.toString()); //System.out.println("Result size: " + results.size()); long totalTime = (System.nanoTime() / 1000000) - startTime; System.out.println("Total TTP: " + totalTime + "ms"); if (results == null || results.size() == 0) { forwardPath = "home.jsp"; } else if (results.size() == 1) { forwardPath = "product.jsp"; } else { forwardPath = "category.jsp"; } } catch (Exception ex) { System.err.println(ex); } System.out.println("Returning view: " + forwardPath); return forwardPath; } }

  • OutputDebugString + DebugView = not tabs!

    - by Steve
    I am dumping \t delimited data using using OutputDebugString and then use ex-Sysinternals DebugView to capture it. The problem is that all the data in DebugView appear to be space delimited, hence I need to perfrorm CTRL+H "\x20" "t" to replace spaces with the tabs before I can use it (I really need tab delimited data). Is there anyway to tell DebugView not to replace tabs with spaces? Or maybe there is a better tool available to capture output of the OutputDebugString function? Any ideas are very welcome!

  • Is it ok to return a reference of a function scope static variable?

    - by kartik
    I wanted to know if that has any ill effects under any circumsatnce. For ex: Ex1: void* func1() { void* p_ref = NULL; //function scope static variable static int var1 = 2; p_ref = &var1; return p_ref; } Ex2: //file scope static variable static int var2 = 2; void* func2() { void* p_ref = NULL; var2 = 3; p_ref = &var2; return p_ref; } So in the above two cases what is the difference apart from the fact that var1 is function scope and var2 is file scope. Thanks in advance.

  • ExceptionHandling with Spring 3

    - by mjf
    I have this controller: @RequestMapping(value = "*.xls", method = RequestMethod.GET) public String excel(Model model) { return "excel"; The excel wiew opens actually a ExcelViewer, which is build in method protected void buildExcelDocument(Map<String, Object> map, WritableWorkbook ww, HttpServletRequest hsr, HttpServletResponse hsr1) throws Exception { Class.writecontent Class.writeMoreContent Called methods write content to the Excel sheet and they can throw e.g biffException.

  • Python 3.0 - Dynamic Class Instance Naming

    - by Jon
    I want to use a while loop to initialize class objects with a simple incremented naming convention. The goal is to be able to scale the number of class objects at will and have the program generate the names automatically. (ex. h1...h100...h1000...) Each h1,h2,h3... being its own instance. Here is my first attempt... have been unable to find a good example. class Korker(object): def __init__(self,ident,roo): self.ident = ident self.roo = roo b = 1 hwinit = 'h' hwstart = 0 while b <= 10: showit = 'h' + str(b) print(showit) #showit seems to generate just fine as demonstrated by print str(showit) == Korker("test",2) #this is the line that fails b += 1 The errors I get range from a string error to a cannot use function type error.... Any help would be greatly appreciated.

  • How do I create a user history?

    - by ggfan
    I want to create a user history function that allows shows users what they done. ex: commented on an ad, posted an ad, voted on an ad, etc. How exactly do I do this? I was thinking about... in my site, when they log in it stores their user_id ($_SESSION['user_id']) so I guess whenever an user posts an ad(postad.php), comments(comment.php), I would just store in a database table "userhistory" what they did based on whenever or not their user_id was activate. When they comment, I store the user_id in the comment dbc table, so I'll also store it in the "userhistory" table. And then I would just queries all the rows in the dbc for the user to show it Any steps/improvements I can make? :)

  • How do I make php page return a 503 error (or anything non-200).

    - by Benju
    A former developer wrote or client-server api in PHP. It simply sends messages as xml using post/response in a very simplistic fashion. The problem is that even when there is an error (ex: invalid arguments passed into the server side) we get a HTTP 200 response with a page like this <h4>Unknown error!</h4> In firebug I can see that the actually HTTP response is a 200. How can we send a different response (ie:503) when we programatically detect in our php code that it is appropriate to do so.

  • Why does "xsd:date" of XML Schema Type mapped "javax.xml.datatype.XMLGregorianCalendar" When Schema-to-Java Mapping of JAXB does.

    - by Take
    I don't know why does "xsd:date" of XML Schema Type mapped "javax.xml.datatype.XMLGregorianCalendar" When Schema-to-Java Mapping of JAXB does. Why does "xsd:date" of XML Schema Type mapped "java.util.Date" ? I guess that JAXB intentionally does its mapping. I want to know that reason if any. And if exists it, how to change "xsd:date" of XML Schema Type to "java.util.Date" of Java class without using annotation(ex.@XmlJavaTypeAdapter). I want to do mashalling and unmarshalling without all annotations.

  • Joomla Session Variable as Plugin Parameter

    - by dosboy
    I have a Joomla plugin which takes varying parameters. I need to retrieve one of these parameters from the current session. I've tried using Jumi and a little PHP snipped to retrieve the value and output it in the plugin's parameter list, but the Joomla plugin parser only handles the outter-most set of curly braces. ex. {fabrik view=table id=62 resetfilters=1 fab_tours_ro___tour_id=[tour_id]} [tour_id] I need to retrieve from the current session. I've tried {fabrik view=table id=62 resetfilters=1 fab_tours_ro___tour_id={jumi [scripts/get_tour_id.php]}} In that case the {jumi} tag never gets parsed. I could hack the {fabrik} plugin, but I'd prefer to do this without making any core or component changes, especially since I update Fabrik quite regularly via svn.
