• Uploading files wont work on production server

  - by Camran

  I have a php script which uploads images to a temporary folder on the server. This works on my local computer with the local (virtual) server. (wampserver). However, on the production server (linux) I cant get it working. Everything is loading as it should, except for that the file doesn't show up on the server. My Q is, is there anything I should think about when moving to a production server with uploading images or files? I have set permissions on the folder where the images are supposed to go to 777 and also the php-code which uploads them to 777. Thanks

• Find the period of over speed ?

  - by Vimvq1987

  Just something interesting come in my mind. Assume that we have a table (in SQL Server) like this: Location Velocity Time What is the best way to determine over speed periods (speed barrier is defined) ? My first idea was loading the table into an array, and then iterate over array to find these periods: (Pseudo C# code) bool isOverSpeed = false; for (int i =0;i<arr.Length;i++) { if (!isOverSpeed) if (arr[i].Velocity > speedBarrier) { #insert the first record into another array. isOverSpeed = true; } if(isOverSpeed) if (arr[i].Velocity < speedBarrier) { #insert the record into that array isOverSpeed = false; } } It works, but somewhat "not very effectively". Is there a "smarter" way, such as a T-SQL query or another algorithm to do this?

• Magento get loaded collection

  - by Zertalx

  Hey guys I got an issue in magento when listing products. $_productCollection = array(); $key = 'product_collection_'.Mage::app()->getRequest()->getRequestUri(); $_productCollection = Mage::helper('cache')->getDataInCache($key); if (empty($_productCollection)) { $_productCollection=$this->getLoadedProductCollection(); Mage::helper('cache')->setDataInCache($key,$_productCollection,'front_end_collection'); } That's my code, i'm loading the collection and saved in cache, the problem is that I added new products from the admin panel but they are not showing up in the listing. I have refreshed cache, reindex all the data and checke that the products were in stock. Also check the visibility because i understand that the collection gets just the visible products, am i correct? I'm using magento enterprise 1.9 I'm new in magento and i'm having troubles understanding how the Collections works, i hope somebody can help me. Thanks

• sIFR 3 - sifr-config.js possibly not running? Not sure what's wrong.

  - by nukegara

  Hi, I've been messing with this for a few hours, and I just can't get the text to be replaced at all. I really can't believe it's taking so long, especially because I did this a few months ago and got it to work in minutes. Anyway, here is my site I'm working on: http://www.moreheadplanetarium.org/regeneration/test/vision.php and I want to replace the h1 tag (Morehead's Vision). I don't know what's wrong, since I've done everything I know to do. I'm jumping back into web design and using Firebug, and when I check the scripts it only has sifr.js and sifr-debug.js in the list, so I'm assuming the config isn't loading but I have no idea what could be the hold up... How do you get the debug to work btw? thanks!

• Zend Framework: How to handle exceptions in Ajax requests?

  - by understack

  Normally when an exception is thrown, Error controller takes command and displays error page with regular common header and footer. This behavior is not wanted in Ajax request. Because in case of error, whole html page is sent over. And in cases where I'm directly loading the content of http response in a div, this is even more unwanted. Instead in case of Ajax request, I just want to receive 'the actual error' thrown by exception. How can I do this? I think, one dirty way could be: set a var in ajax request and process accordingly. Not a good solution.

• An efficient way to store view counts for objects?

  - by Nick Brooks

  I maintain an application where users are able to store images, and then share them. The system is powered by MongoDB at the back end. Most of the image depiction pages are cached as flat HTML files, but I can run some code just before loading the file. I've decided to implement a view count for the system. I am wondering what is the best storage place for that. It should be like Memcached but it should save the viewcounts every hour or so, so even if our server has to be restarted we won't lose the view counts. What is the best solution for that (preferably with a PHP extension as a client)?

• How do i generate random data with RSA?

  - by acidzombie24

  After loading my RSACryptoServiceProvider rsa object i would like to create a key for my AES object. Since i dont need to store the AES key (i only need it to decrypt on my prv side) i figure i dont need to store it and i can generate it with my public key. I thought doing rsa.Encrypt(byte[] with 4 hardcoded bytes); would generate the data i need. It turns out everytime i call this function even with the same data i get different results. So theres no way for me to recreate the AES key if its different everytime. How can i generate data with RSA in a way that i can recreate anytime i need?

• Callback exception/error handling for ASP TreeView OnTreeNodePopulate?

  - by MHutchinson

  We're using an asp:TreeView configured with lazy loading. The callback method assigned for OnTreeNodePopulate throws an exception if the user has been logged out since the page was loaded. What we want to do is to direct the user to the login page. First attempt was to catch the exception on the server and try Response.Redirect(...), but that doesn't work because you can't redirect within a callback. I've tried various other approaches, including using ClientScript.RegisterStartupScript(...) but that doesn't seem to work for OnTreeNodePopulate. If there was some way we could hook into the callback event handling on the client side then it would be easy, but the TreeView doesn't seem to offer anything here. Suggestions?

• Why does my ConfirmButtonExtender cause full postbacks after I've toggled its parent usercontrol's v

  - by zk812

  Hello all, I have a series of usercontrols on a page that are displayed based on a selection. Each usercontrol contains a Delete button with a ConfirmButton/ModalPopupExtender combo attached to it. This works great when first loading any of the usercontrols--clicking delete shows my Confirm Modal popup and hitting yes or no causes an async postback to perform the operation. But if I move away from the usercontrol and come back to it, the Confirm Modal Popup appears but clicking yes or no now causes a full postback (the operation does still take place). Why does changing the visible property cause this?

• Targeting an iFrame once with jQuery

  - by user275074

  Hi, I have a series of frames (4) which are used in a page to create loading of dynamic content through Ajax calls. In each of these frames I target parent level elements and update them with there respective content e.g. $("#loadingGrid1",top.document).show(); $("#frameSkills",top.document).hide(); In jQuery is there a way to instead of targeting specific elements on the parent page multiple times, simply target the page once into a variable e.g. var parentPage=$('#frameSkills',top.document); And then use this variable to apply content like $(parentPage #loadingGrid1).hide() Hope I've explained what I'm after enough. Basically, I'm having to call "top.document" in every jQuery selector I make and it seems like a waste of energy.

• IE Hanging on jQuery code

  - by OrangeRind

  Here's another clichéd problem, but I couldn't find an exact match to this. I haven't posted any source here, as you can freely see all that is there on the link. :-) Statement:I have a web page at http://agrimgupta.com/antaragni/ Disclaimer: Pardon me for the pathetic coding on that page. ;-) It was done on a very short interval. Improvements will be done at a later stage. Observation: This page is functioning normally on my localhost on all browsers. Problem: IE 8 is crawling (nearly hanging) while loading this page from the website. Although it is working fine on localhost. When on the website, It fails to render the mouseover effects, doing them in almost what seems like a minute. Question: How to resolve this stuck up of IE? It is necessary to resolve this. Thanks in Advance

• Waiting for DialogActivity to return before continuing executing of the main thread

  - by jax

  How would I force the current thread to wait until another has finished before continuing. In my program the user selects a MODE from an AlertDialog, I want to halt executing of the program before continuing as the mode holds important configuration for the gameplay. new AlertDialog.Builder(this) .setItems(R.array.game_modes, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { switch (which) { case 0: setMode(TRAINING_MODE); case 1: setMode(QUIZ_MODE); default: setMode(TRAINING_MODE); break; } //continue loading the rest of onCreate(); contineOnCreate(); } }) .create().show(); If this is impossible can anyone give a possible solution?

• InvalidCastException: System.Web.UI.PartialCachingControl -> MyCustomControl when OutputCaching

  - by marcinn

  The problem: I am unable to use OutputCaching with my controls which derives from MyCustomControl. Controls are loaded dynamically using definitions from database with Page.LoadControl method. When I add to ascx <%@ OutputCache VaryByParam="*" Duration="3600"% the "InvalidCastException: System.Web.UI.PartialCachingControl - MyCustomControl" exception is thrown. I am unable to modify assembly witch contains dynamic loading controls logic. Is there any way to fix it in derived controls? The second question is about iis7 and native output caching - is it resolves this problem? (I tried to set up several performance counters and I saw that cache wasn't hit...)

• Feed char array into stdin

  - by Brian Lindsey

  I am writing a parser for a mini scripting language. Some of my grammar rules require jumping to a different location in the file to obtain information. There doesn't seem to be a straightforward way to accomplish this. So, I was thinking about loading my data files into a char array array and parsing line by line. This will allow me to jump all over the array with ease. My question is, is it possible to feed char arrays (i.e. char *) into stdin, so I can easily invoke the yyparse() function as needed.

• MVC more specified models should be populated by more precise query too?

  - by KevinUK

  If you have a Car model with 20 or so properties (and several table joins) for a carDetail page then your LINQ to SQL query will be quite large. If you have a carListing page which uses under 5 properties (all from 1 table) then you use a CarSummary model. Should the CarSummary model be populated using the same query as the Car model? Or should you use a separate LINQ to SQL query which would be more precise? I am just thinking of performance but LINQ uses lazy loading anyway so I am wondering if this is an issue or not.

• assembly.GetTypes() does not return all types

  - by meta

  I try to lead the types from an .dll (which is also referenced in the executing project). I call: public static void LoadPlugin(string pluginFile) { Assembly assembly = Assembly.LoadFrom(pluginFile); foreach (Type type in assembly.GetTypes()) { // play with it } } It loads just a few of them: public partial class Mathematics : UserControl, IMathematics, IPortable and public partial class Welcome : UserControl but the next one, and some others, are ignored: public partial class Test : UserControl, ITest, IPortable They all stand in the same assembly, under the same namespace. The public static void LoadPlugin(string pluginFile) method is located in other assembly that is also referenced in the executing project. No exceptions are thrown. What could be the issues for not loading all the types? Any ideas?

• Retrieving GET variable via PHP, send to SWF on same script?

  - by letseatfood

  Is it possible to retrieve a GET variable within a PHP script and subsequently send the variable data to an SWF on the same script/document? I want the user to select an item on a PHP document and then use a Flash application I am developing to manipulate that data. I know how to load data from a PHP script into an SWF via URLLoader, but only by initiating the loading process from within the SWF. So, I am asking if it's possible to send the PHP data to the SWF from external source. Would the SWF need to listen in some manner? Is Javascript necessary here? Any advice is greatly appreciated!

• Android app display different blocks of text using the same views.

  - by user465131

  I am sure there is a better way to do what I am doing in my apps. The current one I am trying to improve is a list of military cadences. The way I am doing it now is by loading html files in a web view. What I would like to be able to do is have one view set up and just be able to add the text portion of what I would be displaying with the html file. What would be the best method. I know this is probably a pretty simple thing to do with a sting or array but I am at the very beginner level and would need to be pointed in the right direction to do it.

• Implementing prompts in text-input

  - by AntonAL

  Hi, I have a form with some text-inputs: login, password. If user sees this form the first time, input-texts should "contain" prompts, like "enter login", "enter password". If user clicks text-input, it's prompt should disappear to allow typing. I have seen various examples, that uses background image with prerendered text on it. Those images are appearing with following jQuery: $("form > :text").focus(function(){ // hide image }).blur(function(){ // show image, if text-input is still empty if ( $(this).val() == "" ) // show image with prompt }); This approach has following problems: localization is impossible need to pre-render images for various textual prompts overhead with loading images How do you overcomes such a problems ?

• How to extract data from Google Analytics and build a data warehouse (webhouse) from it?

  - by nkaur301

  I have click stream data such as referring URL, top landing pages, top exit pages and metrics such as page views, number of visits, bounces all in Google Analytics. I am required to build a data warehouse from scratch(which I believe is known as web-house) from this data. My questions are:- 1)Is it possible? Every day data increases (some in terms of metrics or measures such as visits and some in terms of new referring sites), how would the process of loading the warehouse go about? 2)What ETL tool would help me to achieve this? Pentaho I believe has a way to pull out data from Google Analytics, has anyone used it? How does that process go? Any references, links would be appreciated besides answers.

• Portrait vs Landscape Launch Images

  - by andrewx

  An iPad app can support inclusion of launch images in both orientations; presumably, if your app supports auto-rotation, then this would suggest to me that if the user launches an app while the device is in Landscape mode, then the Landscape launch image is used. But in all the apps I've built and released, this has never been the case. Never once has the Landscape launch image appeared, only the Portrait. After loading, the app will auto-rotate to whatever orientation the device is in, but at launch, it assumes you are in Portrait. Always. Why? I have seen many other apps in the store that behave this way, but then there are some seem to always automatically know immediately at first launch, from that first launch image, that you are in Landscape, if that's the case. How is this done?

• Arrays and application data

  - by s0mmer

  Hello everyone, At the moment i'm making an application where it is possible to make profiles with different settings. Which datatypes would you recommend me saving these information in? I have a table which is showing the profile name and the version number. But for each profile there need to be stored more information. Therefore the idea i'm working on have 2 arrays. 1 for all the profile information and 1 who is being made when loading the information. The second array is the one going to be showed in the table. Because the table doesnt show all the stored information. .. but this seems kinda stupid. Is there a more suitable method for saving the information in like 1 array, and just pass part of the data to the tableview?
