  • feedparser - various errors

    - by Eiriks
    I need feedparser (se http://www.feedparser.org) for a project, and want to keep third party modules in a separate folder. I did this by adding a folder to my python path, and putting relevant modules there, among them feedparser. This first attempt to import feedparser resulted in import feedparser Traceback (most recent call last): File "", line 1, in File "/home/users/me/modules/feedparser.py", line 1 ed socket timeout; added support for chardet library ^ SyntaxError: invalid syntax I found the text "socket timeout; added..." in the comments at the bottom of the file, removed these comments, and tried again: import feedparser Traceback (most recent call last): File "", line 1, in File "/home/users/me/modules/feedparser.py", line 1 = [(key, value) for key, value in attrs if key in self.acceptable_attributes] ^ IndentationError: unexpected indent Ok, so some indent error. I made sure the indent in the function in question where ok (moved some line breaks down to no-indent). And tried again: import feedparser Traceback (most recent call last): File "", line 1, in File "/home/users/me/modules/feedparser.py", line 1 , value) for key, value in attrs if key in self.acceptable_attributes] ^ SyntaxError: invalid syntax As much I google, I cannot find anything wrong with the syntax: def unknown_starttag(self, tag, attrs): if not tag in self.acceptable_elements: if tag in self.unacceptable_elements_with_end_tag: self.unacceptablestack += 1 return attrs = self.normalize_attrs(attrs) attrs = [(key, value) for key, value in attrs if key in self.acceptable_attributes] _BaseHTMLProcessor.unknown_starttag(self, tag, attrs) Now what? Is my approach all wrong? Why do I keep producing these errors in a module that seems so well tested and trusted?

  • Generated signed X.509 client certificate is invalid (no certificate chain to its CA)

    - by Genady
    I use Bouncy Castle for generation of X.509 client certificates and sing them using a known CA. First I read the CA certificate from the certificate store, generate the client certificate, sign it using the CA. Validation of the certificate is failed doe to the following issue A certificate chain could not be built to a trusted root authority. As I understand this is due to the certificate not being related to the CA. Here is a code sample: public static X509Certificate2 GenerateCertificate(X509Certificate2 caCert, string certSubjectName) { // Generate Certificate var cerKp = kpgen.GenerateKeyPair(); var certName = new X509Name(true,certSubjectName); // subjectName = user var serialNo = BigInteger.ProbablePrime(120, new Random()); X509V3CertificateGenerator gen2 = new X509V3CertificateGenerator(); gen2.SetSerialNumber(serialNo); gen2.SetSubjectDN(certName); gen2.SetIssuerDN(new X509Name(true,caCert.Subject)); gen2.SetNotAfter(DateTime.Now.AddDays(100)); gen2.SetNotBefore(DateTime.Now.Subtract(new TimeSpan(7, 0, 0, 0))); gen2.SetSignatureAlgorithm("SHA1WithRSA"); gen2.SetPublicKey(cerKp.Public); AsymmetricCipherKeyPair akp = DotNetUtilities.GetKeyPair(caCert.PrivateKey); Org.BouncyCastle.X509.X509Certificate newCert = gen2.Generate(caKp.Private); // used for getting a private key X509Certificate2 userCert = ConvertToWindows(newCert,cerKp); if (caCert22.Verify()) // works well for CA { if (userCert.Verify()) // fails for client certificate { return userCert; } } return null; } private static X509Certificate2 ConvertToWindows(Org.BouncyCastle.X509.X509Certificate newCert, AsymmetricCipherKeyPair kp) { string tempStorePwd = "abcd1234"; var tempStoreFile = new FileInfo(Path.GetTempFileName()); try { // store key { var newStore = new Pkcs12Store(); var certEntry = new X509CertificateEntry(newCert); newStore.SetCertificateEntry( newCert.SubjectDN.ToString(), certEntry ); newStore.SetKeyEntry( newCert.SubjectDN.ToString(), new AsymmetricKeyEntry(kp.Private), new[] { certEntry } ); using (var s = tempStoreFile.Create()) { newStore.Save( s, tempStorePwd.ToCharArray(), new SecureRandom(new CryptoApiRandomGenerator()) ); } } // reload key return new X509Certificate2(tempStoreFile.FullName, tempStorePwd); } finally { tempStoreFile.Delete(); } }

  • cxf jaxws with spring on gwt 2.0

    - by Karl
    Hi, I'm trying to use an application which uses cxf-jaxws in bean definition: <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:sec="http://cxf.apache.org/configuration/security" xmlns:jaxws="http://cxf.apache.org/jaxws" xmlns:util="http://www.springframework.org/schema/util" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://cxf.apache.org/configuration/security http://cxf.apache.org/schemas/configuration/security.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-2.0.xsd"> however in combination with the jetty from gwt 2.0 development shell my context doesn't load and I get this exception: org.springframework.web.context.ContextLoader: Context initialization failed org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://cxf.apache.org/jaxws] enter code hereOffending resource: class path resource [bean_definition.xml] My project is maven-based and I got cxf-rt-frontend-jaxws which contains the namespacehandler and spring.handlers on the classpath.

  • Problems with MediaRecorder class setting audio source - setAudioSource() - unsupported parameter

    - by arakn0
    Hello everybody, I'm new in Android development and I have the next question/problem. I'm playing around with the MediaRecorder class to record just audio from the microphone. I'm following the steps indicated in the official site: http://developer.android.com/reference/android/media/MediaRecorder.html So I have a method that initializes and configure the MediaRecorder object in order to start recording. Here you have the code: this.mr = new MediaRecorder(); this.mr.setAudioSource(MediaRecorder.AudioSource.MIC); this.mr.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP); this.mr.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); this.mr.setOutputFile(this.path + this.fileName); try { this.mr.prepare(); } catch (IllegalStateException e) { Log.d("Syso", e.toString()); e.printStackTrace(); } catch (IOException e) { Log.d("Syso", e.toString()); e.printStackTrace(); } When I execute this code in the simulator, thanks to logcat, I can see that the method setAudioSource(MediaRecorder.AudioSource.MIC) gives the next error (with the tag audio_ipunt) when it is called: ERROR/audio_input(34): unsupported parameter: x-pvmf/media-input-node/cap-config-interface;valtype=key_specific_value ERROR/audio_input(34): VerifyAndSetParameter failed And then when the method prepare() is called, I get the another error again: ERROR/PVOMXEncNode(34): PVMFOMXEncNode-Audio_AMRNB::DoPrepare(): Got Component OMX.PV.amrencnb handle If I start to record bycalling the method start()... I get lots of messages saying: AudioFlinger(34):RecordThread: buffer overflow Then...after stop and release,.... I can see that a file has been created, but it doesn't seem that it been well recorderd. Anway, if i try this in a real device I can record with no problems, but I CAN'T play what I just recorded. I gues that the key is in these errors that I've mentioned before. How can I fix them? Any suggestion or help?? Thanks in advanced!!

  • SmartGWT TreeGrid Selection

    - by wonderbread988
    I have a SmartGWT webapp that uses a TreeGrid with a dataSource. I would like this treeGrid to preselect values saved in a cookie. I have gotten the value to be saved in the cookie correctly, however I have tried several different methods of getting the treeGrid to select these values and I can not get it to work. I am attempting to do this in the onmoduleLoad method in my entry point. I have tried: Cookies.setCookie( "selectedUnit", TreeGrid.getSelectedPaths() ) to set the cookie and then when the page is reloaded: TreeGrid.setSelectedPaths( Cookies.getCookie("selectedUnit" ) When I could not get that to work, I tried storing just the id of the item selected: Cookies.setCookies( "selectedUnit", TreeGrid.getSelected().getAttribute("id") ) and then onLoad attempting to find that record and select it: TreeGrid.selectRecord( TreeGrid.getTree().find("id", Cookies.getCookie("selectedUnit") ) ) This did not work either, so finally I tried storing TreeGrid.getSelectedState() and upon retrieving that value form the cookie onLoad, passing it to TreeGrid.setSelectedState() similar to my first attempt, but passing state instead of path. I could not get any of these things to work. Can I not tell the TreeGrid to select an item in the 'OnmoduleLoad' method? Is this action only valid after the TreeGrid has been drawn? If that is the case where and how can I do this? Thank you in advance for any help you can give.

  • How to control the download url for dotNetFx35setup.exe without using the Visual Studio bootstrapper

    - by tronda
    Previously I've used to Visual Studio 2008 setup.bin to generate a bootstrapper. I had some issues with it which were difficult to resolve and turned to dotNetInstaller. One great thing with the VS 2008 generated bootstrapper, was that I was able to control the download location for the .NET framework. By using the MSBuild task I could specify the componentsLocation: <GenerateBootstrapper ApplicationFile="$(TargetFileName)" ApplicationName="MyApp" ApplicationUrl="http://$(InstallerHost)$(DownloadUrl)" BootstrapperItems="@(BootstrapperFile)" CopyComponents="True" ComponentsLocation="Relative" OutputPath="$(OutputPath)" Path="C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bootstrapper\" /> Here I'm able to use the ComponentsLocation="Relative" and the bootstrapper would download from our own web server - which is what I want. When I no longer have the VS 2008 bootstrapper, I would like to have the same feature. The new boostrapper downloads the dotNetFx35setup.exe from a defined server, but the problem is that this ".NET bootstrapper" connects to Microsoft's servers for downloading the needed packages. Trying to run the following command: dotNetFx35setup.exe /? did not show any options to control the download location. The web server will contain the package structure which the Windows SDK (v6.0A) has within the Bootstrapper\Packages directory. The structure looks like this: Packages DotNetFX DotNetFX30 DotNetFX35 DotNetFx35Client DotNetFx35SP1 ..... When I state a dependency to the .NET Framework 3.5, the DotNetFX35 directory structure gets copied into the bin/Debug directory. I've copied this directory onto the web server and it looks like this: DotNetFX35 dotNetFX20 dotNetFX30 dotNetFX35 x64 netfx35_x64.exe x86 netfx35_x86.exe dotNetMSP dotNetFx35setup.exe The other directories contains mainly MSI, MSP and MSU files. So any pointers on how to control downloading of the .NET framework. Shouldn't I use the dotNetFx35setup.exe file? If not - which should I use?

  • Cannot connect to a SQL Server 2005 Analysis Services cube after installing SQL Server 2008 SP1.

    - by Luc
    I've been developing an application that talks directly to an SSAS 2005 OLAP cube. Note that I also have SQL Server 2008 installed, so the other day I did a Windows Update and decided to include SQL Server 2008 SP1 in my update. After doing that, my SSAS 2005 cube is no longer accessible from my application. I'm able to browse the data just fine within SQL Server 2005 BI Studio Manager, but I'm not able to connect to the cube from my application. Here is my connection string that used to work: Data Source=localhost;Provider=msolap;Initial Catalog=Adventure Works DW Here is the error message I get: Either the user, [Server]/[User], does not have access to the Adventure Works DW database, or the database does not exist.

  • Integrating CKFinder with InnovaStudio WYSIWYG Editor

    - by Sonny
    I use InnovaStudio WYSIWYG Editor, and I am trying to replace InnovaStudio's Asset Manager with CKFinder. There's a line in the editor configuration for what URL to use for the asset manager. I have pointed it at CKFinder. The part I can't get to work is getting the field to populate with the double-clicked file's path from CKFinder. It appears to use the 'func' parameter to specify the callback function. The URL I'm calling is: /common/ckfinder/ckfinder.html?action=js&func=setAssetValue The InnovaStudio WYSIWYG Editor provides the setAssetValue(v) callback function for setting the field value. The v parameter should hold the URL. CKFinder pops up as expected when it's invoked, but neither double-clicking the thumbnails nor using the "select" option in the context menu works. The normal/expected behavior is that CKFinder closes and the target field is populated with the URL for the selected asset. Additional Info: The InnovaStudio WYSIWYG Editor has a "popup" for adding an image or flash file to the content. This pop-up is in an iframe. When it calls CKFinder (or it's own asset manager), that is also in an iframe. It appears that CKFinder is looking in the scope of the main window rather than the image/flash iframe that actually contains the field that needs to be populated.

  • Crystal Reports Images not loading in ASP.NET MVC

    - by Ryan Shripat
    I'm using Crystal Reports in a Webform inside of an MVC application. Images in the reports are not being displayed, however, on both the ASP.NET Development Server and IIS 7 (on Win7x64). I know from a number of other questions similar to this that the CrystalImageHandler HTTP Handler is responsible for rendering the image, but I've tried all of the usual solutions to no avail. So far, I have Added the following to my appSettings (via http://www.mail-archive.com/[email protected]/msg26882.html) <add key="CrystalImageCleaner-AutoStart" value="true" /> <add key="CrystalImageCleaner-Sleep" value="60000" /> <add key="CrystalImageCleaner-Age" value="120000" /> Added the following httpHandler to system.web/httpHandlers (via http://stackoverflow.com/questions/2253682/crystal-report-viewer-control-isnt-loading-the-images-inside-the-report) <add verb="GET" path="CrystalImageHandler.aspx" type="CrystalDecisions.Web.CrystalImageHandler, CrystalDecisions.Web, Version=12.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"/> Added the following to my Global.asax.cs (via http://stackoverflow.com/questions/2006011/crystal-reports-images-and-asp-net-mvc) routes.IgnoreRoute("{resource}.aspx/{*pathInfo}"); and routes.IgnoreRoute("CrystalImageHandler.aspx"); Any ideas as to why the images still 404?

  • Code Golf: Collatz Conjecture

    - by Earlz
    Inspired by http://xkcd.com/710/ here is a code golf for it. The Challenge Given a positive integer greater than 0, print out the hailstone sequence for that number. The Hailstone Sequence See Wikipedia for more detail.. If the number is even, divide it by two. If the number is odd, triple it and add one. Repeat this with the number produced until it reaches 1. (if it continues after 1, it will go in an infinite loop of 1 -> 4 -> 2 -> 1...) Sometimes code is the best way to explain, so here is some from Wikipedia function collatz(n) show n if n > 1 if n is odd call collatz(3n + 1) else call collatz(n / 2) This code works, but I am adding on an extra challenge. The program must not be vulnerable to stack overflows. So it must either use iteration or tail recursion. Also, bonus points for if it can calculate big numbers and the language does not already have it implemented. (or if you reimplement big number support using fixed-length integers) Test case Number: 21 Results: 21 -> 64 -> 32 -> 16 -> 8 -> 4 -> 2 -> 1 Number: 3 Results: 3 -> 10 -> 5 -> 16 -> 8 -> 4 -> 2 -> 1 Also, the code golf must include full user input and output.

  • Need help replicating directory structure with ColdFusion and jsTree

    I am using this new jQuery plugin called jsTree www.jstree.com and using the HTML datasource. I am also using ColdFusion 7 with cfdirectory and filtering out files, so just dirs. I need to recreate the directory structure in the image, well any dir structure I give it actually. I am having a heck of a time with the logic. variables.imageDirectoriesLen = 8 in this scenario cause I am outputting from the middle of the actual file path, not from begining. Thanks for the help.

  • spring-mvc binding arraylist in form

    - by Mike
    In my controller I added an ArrayList to my model with the attribute name "users". Now I looked around and this is the method I found (including a question here): <form:form action="../user/edit" method="post" modelAttribute="users"> <table> <c:forEach var="user" items="${users}" varStatus="counter"> <tr> <td> <form:input path="users[${counter.index}].age"/> </td> <td><button type="submit" name="updateId" id="Update" value="${user.id}">Update</button></td> </tr> </c:forEach> </table> </form:form> But when I load the JSP page I get: .springframework.beans.NotReadablePropertyException: Invalid property 'projects[0]' of bean class [java.util.ArrayList]: Bean property 'users[0]' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter? So apparantely this isn't the way to go, but in that case how do I bind an arraylist so I can edit the values?

  • Need content in UIWebView to display quickly

    - by leftspin
    Part of my app caches web pages for offline viewing. To do that, I am saving the HTML fetched from a site and rewriting img urls to point to a file on the local store. When I load the html into a UIWebView, it loads the images as expected and everything's fine. I am also caching stylesheets in this fashion. The problem is that when I put the phone into airplane mode, loading this cached html causes the UIWebView to display a blank screen and pause for a while before displaying the page. I've figured out that it's caused by non-cached URLs referenced from the original HTML doc that the web view is trying to fetch. These other URLs include images within the cached stylesheets, content in iframes, and javascript that opens a connection to fetch other resources. The pause happens when the UIWebView tries to fetch these resources, and the web page only appears after all these other fetches have timed out. My questions is, how can I make UIWebView just display the stuff I've cached immediately? Here are my thoughts: write even more code to cache these other references. This is potentially a ton more code to catch all the edge cases, etc., especially having to parse the Javascript to see what it loads after the page is loaded force UIWebView to time out immediately so there's no pause. I haven't figured out how to do this. somehow get what's already loaded to display even though the external references haven't finished fetching yet strip the code of all scripts, link tags and iframes to "erase" the external references. I've tried this one, but for some sites, the resultant page is severely messed up Can anyone help me here? I've been working on this forever, and am running out of ideas.

    Hello, im trying to use the jQuery UI autocomplete to communitate with a webservice with responseformate JSON, but i am unable to do so. My webservice is not even executed, the path should be correct since the error message does not complain about this. What strikes me is the headers, response is soap but request is json, is it supposed to be like this? Response Headersvisa källkod Content-Type application/soap+xml; charset=utf-8 Request Headersvisa källkod Accept application/json, text/javascript, */* Content-Type application/json; charset=utf-8 The error message i get is as follows (sorry for the huge message, but it might be of importance): soap:ReceiverSystem.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Xml.XmlException: Data at the root level is invalid.

  • Help with stock ticker style scrolling using Core Animation

    - by Glen Harding
    Hi, I'm looking for some guidance on the best way to implement stock ticker style right-to-left scrolling of CALayers in Core Animation on OSX. I'm pretty new to Cocoa and don't know the best way to implement this. I have a continuous stream of news items and stock details that I turn into CALayers (made up of 1 image and a CATextLayer) and I want to animate the CALayers from right to left of my custom view. The news and stock information is constantly updating so I would like to add 1 item at a time to the view, scroll it right to left until the right-most point of the CALayer is showing, then add another CALayer to the view and start scrolling that as well. I would like to do this dynamic updating instead of taking a big snapshot of all my data, turning it into a big horizontal CALayer and scrolling that. I'm looking for guidance on how to achieve this sort of effect - do I manually animate each new CALayer along a path in the view? Or should I be using CAScrollLayer to achieve this effect? Many thanks Glen.

  • Zend Studio Debugger returns Application Error

    - by Keyne
    When I run debug for my public/index.php I got an application error as output. I've seen that it occurs at this line: foreach($feed->findFeedEntries($entriesLimit) as $entry) If I put a breakpoint before this, all works as expected, I mean, the error is after the line above. If I remove findFeedEntries() method, I can perform debugging without erros. To clarify, this method is in my row object as described bellow: This is the error <?php class Model_DbTable_FeedEntries extends Zf_Db_Table { public function fetchNewEntries($feed_id) { $Feeds = new Model_DbTable_Feeds(); $Feed = $Feeds->getById($feed_id); // ERROR IS HERE! The colum doesn't exists! // And this is only on zend-debugger!!! var_dump($Feed->link) // ... } } I'm completely lost about what's happening, once my application has no errors, the problem is with zend-debugger. The error is: An error occurred Application error Exception information: Message: Specified column "link" is not in the row Stack trace: #0 C:\Program Files\xampp\htdocs\desenvolvimentistas\application\models\DbTable\FeedEntries.php(75): Zend_Db_Table_Row_Abstract->__get('link') #1 C:\Program Files\xampp\htdocs\desenvolvimentistas\application\models\DbTable\FeedEntries.php(50): Model_DbTable_FeedEntries->fetchNewEntries('1') #2 C:\Program Files\xampp\htdocs\desenvolvimentistas\application\models\DbTable\Row\Feed.php(15): Model_DbTable_FeedEntries->getAllByFeedId('1', 1) #3 C:\Program Files\xampp\htdocs\desenvolvimentistas\application\modules\default\controllers\IndexController.php(41): Model_DbTable_Row_Feed->findFeedEntries(1) #4 C:\Program Files\xampp\htdocs\ZendFramework-1.10.0-minimal\library\Zend\Controller\Action.php(513): IndexController->indexAction() #5 C:\Program Files\xampp\htdocs\ZendFramework-1.10.0-minimal\library\Zend\Controller\Dispatcher\Standard.php(289): Zend_Controller_Action->dispatch('indexAction') #6 C:\Program Files\xampp\htdocs\ZendFramework-1.10.0-minimal\library\Zend\Controller\Front.php(954): Zend_Controller_Dispatcher_Standard->dispatch(Object(Zend_Controller_Request_Http), Object(Zend_Controller_Response_Http)) #7 C:\Program Files\xampp\htdocs\ZendFramework-1.10.0-minimal\library\Zend\Application\Bootstrap\Bootstrap.php(97): Zend_Controller_Front->dispatch() #8 C:\Program Files\xampp\htdocs\ZendFramework-1.10.0-minimal\library\Zend\Application.php(366): Zend_Application_Bootstrap_Bootstrap->run() #9 C:\Program Files\xampp\htdocs\desenvolvimentistas\public\index.php(54): Zend_Application->run() #10 C:\Users\RAPOSO\AppData\Local\Temp\dummy.php(1): include('C:\Program File...') #11 {main} I've notice that when I get the row object my colums names are not right. Instead of have "title", "link", ... I have "feeds", "desenvolvimentistas" (projectname), and so on...

  • Webforms MVP Passive View - event handling

    - by ss2k
    Should the view have nothing event specific in its interface and call the presenter plain methods to handle events and not have any official EventHandlers? For instance // ASPX protected void OnSaveButtonClicked(object sender, EventArgs e) { _Presenter.OnSave(); } Or should the view have event EventHandlers defined in its interface and link those up explicitly to control events on the page // View public interface IView { ... event EventHandler Saved; ... } // ASPX Page implementing the view protected override void OnInit(EventArgs e) { base.OnInit(e); SaveButton.Click += delegate { Saved(this, e); }; } // Presenter internal Presenter(IView view,IRepository repository) { _view = view; _repository = repository; view.Saved += Save; } The second seems like a whole lot of plumbing code to add all over. My intention is to understand the benefits of each style and not just a blanket answer of which to use. My main goals is clarity and high value testability. Testability overall is important, but I wouldn't sacrifice design simplicity and clarity to be able to add another type of test that doesn't lead to too much gain over the test cases already possible with a simpler design. If a design choice does off more testability please include an example (pseudo code is fine) of the type of test it can now offer so I can make my decision if I value that type of extra test enough. Thanks!

  • C# Assembly.GetTypes() - ReflectionTypeLoadException

    - by Veskechky
    We implement a plugin framework for our application and load plugin assemblies using Assembly.Loadfrom. We then use GetTypes() and further examine the types with each plugin file for supported Interfaces. A path for the plugins is provided by the user and we cycle through each of the files in the folder to see if it (the plugin) supports our plugin interface. If it does, we create an instance, if not we move onto the next file. We build two versions of software from the one code base (appA_1 and appA_2). Loading the plugins works well when the plugins are loaded by the application that was built at the same time as the plugin file. However if we build appA_2 and point to the plugin folder of appA_1, we get an exception when GetTypes() is called. A basic version of our code is; var pluginAssembly = Assembly.LoadFrom(FileName); foreach (var pluginType in pluginAssembly.GetTypes()) { We get a "ReflectionTypeLoadException" exception. This is concerning because we want our application to be able to load the types of any plugin, built by anyone. Is there something we are missing?

  • dbExpress error in Delphi 2010

    The below code works in Delphi 2007, but it gives me this error in Delphi 2010: --------------------------- Error --------------------------- Cannot load oci.dll library (error code 127). The oci.dll library may be missing from the system path or you may have an incompatible version of the library installed. --------------------------- OK Details >> --------------------------- The exception is raised when I set "connected" to "true". I have tried placing a copy of "oci.dll" in the same folder as the .exe file, but I get the same message. I also get this message when using the form designer and a visible TSQLConnection component. Any thoughts? function TDBExpressConnector.GetConnection(username, password, servername: string) : TSQLConnection; begin //take a username, password, and server //return a connected TSQLConnection try FSqlDB := TSQLConnection.Create(nil); with FSqlDB do begin Connected := False; DriverName := 'Oracle'; GetDriverFunc := 'getSQLDriverORACLE'; KeepConnection := True; LibraryName := 'dbxora30.dll'; ConnectionName := 'OracleConnection';; Params.Clear; Params.Add('DriverName=Oracle'); Params.Add('DataBase=' + servername); Params.Add('User_Name=' + username); Params.Add('Password=' + password); Params.Add('RowsetSize=20'); Params.Add('BlobSize=-1'); Params.Add('ErrorResourceFile='); Params.Add('LocaleCode=0000'); Params.Add('Oracle TransIsolation=ReadCommited'); Params.Add('OS Authentication=False'); Params.Add('Multiple Transaction=False'); Params.Add('Trim Char=False'); Params.Add('Decimal Separator=.'); LoginPrompt := False; Connected := True; end; Result := FSqlDB; except on e:Exception do raise; end; //try-except end;

  • Recursion in an ASP.NET MVC view

    - by Dennis Palmer
    I have a nested data object for a set of items within categories. Each category can contain sub categories and there is no set limit to the depth of sub categories. (A file system would have a similar structure.) It looks something like this: class category { public int id; public string name; public IQueryable<category> categories; public IQueryable<item> items; } class item { public int id; public string name; } I am passing a list of categories to my view as IQueryable<category>. I want to output the categories as a set of nested unordered list (<ul>) blocks. I could nest foreach loops, but then the depth of sub categories would be limited by the number of nested foreach blocks. In WinForms, I have done similar processing using recursion to populate a TreeView, but I haven't seen any examples of using recursion within an ASPX MVC view. Can recursion be done within an ASPX view? Are there other view engines that include recursion for view output?

  • Version control a content management system?

    - by Mike
    I have the following directory structure in the CMS application we have written: /application /modules /cms /filemanager /block /pages /sitemap /youtube /rss /skin /backend /default /css /js /images /frontend /default /css /js /images Application contains code specific to the current CMS implementation, i.e code for this specific cms. Modules contain reusable portions of code that we share across projects, such as libraries to work with youtube or rss feeds. We include these as git submodules, so that we can update the module in any website and push the changes back across all other projects. It makes it really easy to apply a change to our code and distribute it. We wanted to turn the CMS into a module so we get the same benefit - we can run the entire project under source control, then update the cms as required through a git-submodule. We have run into a problem however: the cms requires javascript/images/css in order for it to work correctly. Things we have thought about: We could create 2 submodules, one for cms-skin and one for cms, but this means you cannot "git pull" one version without having some idea of which versions of skin work with which versions of cms. i.e version 1.2.2 CMS might have issues with 1.0.3 CMS-Skin We could add the skin to the cms module but this has the following problems: Skin should be available on the document root, module code shouldn't be, and if it is it should probably be secured via .htaccess It doesn't seem to make any sense bundling assets with php code We could create a symlink between /skin/backend/ to go to /modules/cms/skin but does this cause any security problems, and do we want to require something like a symlink for the application to work? We could create a hook for git or a shell script that copies files from modules/cms/skin to skin/backend when an update occurs, but this means we lose the ability to edit CMS core files in a project then push them back How is this typically done in large scale cms's? How is it possible to get the source code for a cms under version control, work on the application for a client, then update the sourcecode as releases and given by the vendor? How do applications like Magento or Drupal do this?
