  • Calling 32 bit unmanaged dlls from C# randomly failing

    - by Bert
    Hi, I'm having an issue when calling 32 bit delphi dll's from c# web site. The code generally runs fine, but occasionally I get an error Unable to load DLL '': The specified module could not be found. (Exception from HRESULT: 0x8007007E). This issue persists until I recycle the app pool for the site, and then it works fine again. On the same server, there is also a web service that is calling the same set of dlls. This web service doesn't seem to have the same issue that the web site has. Both applications are using .net framework 3.5, separate app pools on IIS. Here is the code I'm using to wrap the dlls: public sealed class Mapper { static Mapper instance = null; [DllImport("kernel32.dll")] private static extern bool SetDllDirectory(string lpPathName); private Mapper() { SetDllDirectory(ConfigManager.Path); } public static Mapper Instance { get { if (instance == null) { instance = new Mapper(); } return instance; } } public int Foo(string bar, ref double val) { return Loader.Foo(bar, ref val); } } public static class Loader { [DllImport("some.dll", CallingConvention = CallingConvention.StdCall, CharSet = CharSet.Unicode, EntryPoint = "foo")] public static extern int Foo(string bar, ref double val); } Then I call it like this: double val = 0.0; Mapper.Instance.Foo("bar", ref val); Any ideas as to why it would "randomly" Unable to load DLL '': The specified module could not be found. (Exception from HRESULT: 0x8007007E). The other problem is that I haven't been able to replicate the issue in the development environment. I thought that due to 2 applications calling the same dlls, that there could be some locks occurring. To replicate this, I created an app that spawned multiple threads and repeatedly called the 32bit dlls, and then used the web site to call these same dlls. I still couldn't replicate the issue. Some possible fixes that I can think of: Wrap the 32 bit dlls in web service (because the webservice doesn't seem to suffer from the same problem). But this may be worthless if it turns out that the web service also fails. Set up state server for the session state and periodically recycle the app pool for the site.This isn't fixing the problem, only avoiding it. Wrap the dll's in exe, and call that exe. Then I shouldn't get the same issue. But this also seems like a hacky solution. Implement the mapper class differently ? But how else should I be doing the call? The other draw back is that other applications are using this mapper, so I'd need to change there code too. Thanks

  • Sinatra on Passenger always fails on first attempt

    - by fatnic
    I have a small Sinatra app I'm running on a shared hosting account using Passenger. However, the first time the app is accessed after a while, I get a Passenger error page saying the application could not be started. Usually because Sinatra could not be found. I am assuming this is just a normal delay from when a new instance is spawned. However, is there a way to delay trying to load Siantra until it Passenger has fully loaded?

  • Loading a page into memory in Rails

    - by titaniumdecoy
    My rails app produces XML when I load /reports/generate_report.xml. On a separate page, I want to read this XML into a variable and save it to the database. How can I do this? Can I somehow stream the response from the /reports/generate_report.xml URI into a variable? Or is there a better way to do it since the XML is produced by the same web app?

  • Is there an easy way to get the hostname in Symfony

    - by greg0ire
    I have been searching for an easy way to get the hostname of the machine where Symfony runs in Symfony (so that my app adapts when it is used on a host with a different ServerName), but I couldn't find one. I created a variable in app.yml and I fetch it, but I still wonder if there is no easier way to do this. How are you doing this? I'm using Symfony 1.2 and 1.4 on different projects.

  • Magento set Store Id - customer login - but still logged out

    - by user3564050
    I've got an overridden AccountController in which i set the current store to an other as currently running (example: Customer is in website default and store default, going to login page, click login, my loginPostAction sets the store to id "2" (on website 2) and then executes the parent code loginPostAction. The store is set, of course, but after the login and the redirect to home, the customer is not logged in anymore... Customer-sendlogindata-myaccountcontroller sets store-original account controller logs in without errors (cause $session customer is set)-redirect to home-customer is not logged in anymore... i set the store with Mage::app()-setCurrentStore($id); . And in index.php i've got an extra where the store is set to the right id (2) too and this works... but the customer is not logged in anymore.. is that an issue with the session cause different websites ? I don't want to globally share customer.. each website has his own customers, but every customer has to be able to login on default store. AccountController.php overridden: public $Website_Ids = array( array("code" => "gerstore", "id" => "3", "website" => "ger"), array("code" => "ukstore", "id" => "2", "website" => "uk"), array("code" => "esstore", "id" => "4", "website" => "es"), array("code" => "frstore", "id" => "5", "website" => "fr") ); public function loginPostAction() { $login = $this->getRequest()->get('login'); if(isset($login['username'])) { $found = null; foreach($this->Website_Ids as $WebsiteId) { $customer = Mage::getModel('customer/customer'); $customer->setWebsiteId($WebsiteId['id']); $customer->loadByEmail($login['username']); if(count($customer->getData()) > 0) { $found = $WebsiteId; } } if($found != null && Mage::app()->getStore()->getId() != $found['id']) { /* found, so set currentstore to id */ Mage::app()->setCurrentStore($found['id']); $_SESSION['current_store_b2b'] = $found; } /* not found, doesn't matter cause mage login exception handling */ } parent::loginPostAction(); } Index.php : session_start(); $session = $_SESSION['current_store_b2b']; if($session != null || $session != "") { Mage::app()->setCurrentStore($session['id']); Mage::run($session['code'], 'store'); } else { /* Store or website code */ $mageRunCode = isset($_SERVER['MAGE_RUN_CODE']) ? $_SERVER['MAGE_RUN_CODE'] : ''; /* Run store or run website */ $mageRunType = isset($_SERVER['MAGE_RUN_TYPE']) ? $_SERVER['MAGE_RUN_TYPE'] : 'store'; Mage::run($mageRunCode, $mageRunType); } Whats the matter ? Thanks.

  • iphone uiwebview inital white view

    - by BahaiResearch.com
    My app's main view has a uiwebview. It is white for a split second before it has time to render the HTML the app generates. Is there a way to make the uiwebview black, or another color, before it renders? The flash of white isn't part of my plan for a smooth visual transition. Objective-C or MonoTouch answers are fine, I am bi-lingual.

  • Access Denied when using popen - Python

    - by RadiantHex
    Hi folks, I'm using popen in order to send a few commands within a Django app. Problem is that I'm getting [Error 5] Access Denied, apparently I have no access to cmd.exe, which popen seems to use. WindowsError at /test/cmd/ [Error 5] Access is denied: 'C:\WINDOWS\system32\cmd.exe /c dir' I reckon this is because the app sits behind a web server which has limited privileges. Is there anything we can do about it? Help would be awesome!

  • Android ACTION_SEND Attached File

    - by Sean
    When you attach a file to an e-mail using the ACTION_SEND intent (with the extra EXTRA_STREAM) does the e-mail app copy that attached file to its own location? My app creates a file and attaches it to an email, but this can happen many times and I would like to be able to delete this file when it is no longer needed (so it doesn't flood the user's storage with junk data). Is the file safe to delete after the e-mail intent has started?

  • UITableView: Handle cell selection in a mixed cell table view static and dynamic cells

    - by AlexR
    I am trying to mix dynamic and static cells in a grouped table view: I would like to get two sections with static cells at the top followed by a section of dynamic cells (please refer to the screenshot below). I have set the table view contents to static cells. Edit Based on AppleFreak's advice I have changed my code as follows: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell; if (indexPath.section <= 1) { // section <= 1 indicates static cells cell = [super tableView:tableView cellForRowAtIndexPath:indexPath]; } else { // section > 1 indicates dynamic cells CellIdentifier = [NSString stringWithFormat:@"section%idynamic",indexPath.section]; cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath]; } return cell; } However, my app crashes with error message Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'UITableView dataSource must return a cell from tableView:cellForRowAtIndexPath:' for section 0 and row 0. The cell returned from cell = [super tableView:tableView cellForRowAtIndexPath:indexPath] for section 0 and row 0 is nil. What is wrong with my code? Could there be any problems with my outlets? I haven't set any outlets because I am subclassing UITableViewController and supposedly do not any outlets for tableview to be set (?). Any suggestions on how to better do it? Edit II I have recreated my scene in storyboard (please refer to my updated screen shot above) and rewritten the view controller in order to start from a new base. I have also read the description in Apple's forum as applefreak suggested. However, I run in my first problem with the method numberOfSectionsInTableView:tableView, in which I increment the number of static sections (two) by one. - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return [super numberOfSectionsInTableView:tableView] + 1 ; } The app crashed with the error message: Terminating app due to uncaught exception 'NSRangeException', reason: '* -[__NSArrayI objectAtIndex:]: index 2 beyond bounds [0 .. 1]' Why is this code not working for me even though I followed Apple's and applefreak recommendations? It is possible that the tableView has changed a bit in iOS 6? Solution: I got this to work now using AppleFreaks code sample in his answer below. Thank you, AppleFreak! Edit III: Cell Selection: How can I handle cell selection in a mixed (dynamic and static cells) cell table view? When do I call super and when do I call self tableView? When I use [[super tableView] selectRowAtIndexPath:indexPath animated:NO scrollPosition:UITableViewScrollPositionNone] and try to check for the selected index paths with: UITableView *tableView = [super tableView]; if ( [[tableView indexPathForSelectedRow] isEqual:customGrowthIndexPath] ) { .. } I get an return value of nil. As I can't find the source of my error, I really would appreciate your help

  • Error Handling for Application in PHP

    - by Zubair1
    I was wondering if someone can show me a good way to handle errors in my PHP app, that i am also easily able to reuse in my codes. So far i have been using the following functions: Inline Errors function display_errors_for($fieldname) { global $errors; if (isset($errors[$fieldname])) { return '<label for="' .$fieldname. '" class="error">' . ucfirst($errors[$fieldname]). '</label>'; } else { return false; } } All Errrors function display_all_errors($showCounter = true) { global $errors; $counter = 0; foreach ($errors as $errorFieldName => $errorText) { if ($showCounter == true) { $counter++; echo '<li>' . $counter . ' - <label for="' .$errorFieldName. '">' .$errorText. '</label></li>'; } else { echo '<li><label for="' .$errorFieldName. '">' .$errorText. '</label></li>'; } } } I have a $errors = array(); defined on the top of my global file, so it is appended to all files. The way i use it is that if i encounter an error, i push a new error key/value to the $errors array holder, something like the following: if (strlen($username) < 3) { $errors['username'] = "usernames cannot be less then 3 characters."; } This all works great and all, But i wondering if some one has a better approach for this? with classes? i don't think i want to use Exceptions with try/catch seems like an overkill to me. I'm planning to make a new app, and i'll be getting my hands wet with OOP alot, though i have already made apps using OOP but this time i'm planning to go even deeper and use OOP approach more extensively. What i have in mind is something like this, though its just a basic class i will add further detail to it as i go deeper and deeper in my app to see what it needs. class Errors { public $errors = array(); public function __construct() { // Initialize Default Values // Initialize Methods } public function __destruct() { //nothing here too... } public function add($errorField, $errorDesc) { if (!is_string($errorField)) return false; if (!is_string($errorDesc)) return false; $this->errors[$errorField] = $errorDesc; } public function display($errorsArray) { // code to iterate through the array and display all errors. } } Please share your thoughts, if this is a good way to make a reusable class to store and display errors for an entire app, or is getting more familiar with exceptions and try/catch my only choice?
