  • CodeIgniter - Image Validation & Thumbnailing

    - by Sebhael
    I'm currently trying to create a function that validates and creates thumbnails for images on upload - but I'm quite lost on what I'm doing. I'm assuming I'm off on my terminology so I'm not really getting any search results to help point me in the right direction. My playground is a form with 6 upload fields that are required. One of these fields is for a simple 32x32 icon image, another a portrait orientation (most likely) photo, and then 4 standard desktop screenshots -- and I'm using CodeIgniter as my framework. I would like to create a function that validates/thumbnails images, and only have to call it on the validation if at all possible. I know I can achieve this per-image, since the documentation for CI is quite through on this - but to reduce redundancy I'm looking for the better option. Outside of that, I don't even actually understand in full how to manipulate images unless it's just $this-input-post('field') - then calling all functions onto this? I don't know, I'm confused and posting on the actual CI forums has yielded me nothing - so all I'm really looking for is a point in the right direction to understanding what I'm trying to achieve here. This also all might not make any sense, I know it doesn't to me - but I can explain more if needed. Thanks in advance.

  • How to play music on site preventing direct file download

    - by Hugo Palma
    I'm starting a blog with a hosted wordpress instance and i would like to be able to stream music using a flash player on some posts. The problem is that every player i find uses a simple param to get the file url which makes it very easy for someone to find that url and just download the file. A server side solution can be implemented as i have full access to the server.

  • even small file upload stops activity on apache/rails

    - by Pavel K.
    on my rails(2.3.5) app(currently 50-70rpm, maximum response time around 0.7s), uploading even 700k file(using paperclip plugin) locks up the server for web requests for everyone for 2 minutes! (other apps on same server work normally) does anyone have a clue why that might be happening? i am using some mysql transactions which lock the database also if that might be an issue i read http://www.therailsway.com/2009/4/23/uploading-files but it couldn't be locking server for 2 minutes for a small file, could it?!

  • Automate downloads from password protected website

    - by Andrew
    I need some help with a work project I have been assigned. At the moment we manually go to the site, logon and then download 2 excel files from a supplier's website every month. The files are then loaded into SQL. We want to automate this process. Now the loading of the files into SQL I can do, but I am not sure how I can automate logging onto the website entering my user details and collecting the files. I mostly deal with SQL and have very little .NET experience, so any code samples would be most appreciated.

  • Detect the file size of a link's href using JavaScript

    - by noblethrasher
    Hi, Would like to write a script to detect the file size of the target of a link on a web page. Right now I have a function that finds all links to PDF files (i.e. the href ends with '.pdf') and appends the string '[pdf]' to the innerText. I would like to extend it so that I can also append some text advising the user that the target is a large file (e.g. greater than 1MB). Thanks

    - by Vara Prasad.M
    I having an XML file and that file is under the Documents folder. If I actually give the entire path in C# then I am able to retrieve the XML values, but if I give the project path then it is not getting the values. For example: string fileNamePath=ConfigurationManager.AppSettings["XMLDocPath"].ToString() + fileName; m_xmld.Load(fileNamePath); It is throwing a runtime error.

  • Write file at a specific value and line

    - by user2828891
    I want to write data at a specified value in a text file from a text box. Here is a example: item_begin etcitem 3344 item_type=etcitem is first line and item_begin weapon 3343 item_type=weapon is second. Well i want to replace item_type=weapon at second line with item_type=armor. Here is code so far: var data2 = File.WriteAllLines("itemdata.txt") .Where(x => x.Contains("3343")) .Take(1) .SelectMany(x => x.Split('\t')) .Select(x => x.Split('=')) .Where(x => x.Length > 1) .ToDictionary(x => x[0].Trim(), x => x[1]); But returns error at WriteAllLines. Here is the readline part code: var data = File.ReadLines("itemdata.txt") .Where(x => x.Contains("3343")) .Take(1) .SelectMany(x => x.Split('\t')) .Select(x => x.Split('=')) .Where(x => x.Length > 1) .ToDictionary(x => x[0].Trim(), x => x[1]); //call values textitem_type.Text = data["item_type"]; And want to write the same value I change on textitem_type.Text after read. I used this to reaplace but replaces all values with same name from line and returns me in text only 1 line. Code: private void button2_Click(object sender, EventArgs e) { var data = File .ReadLines("itemdata.txt") .Where(x => x.Contains(itemSrchtxt.Text)) .Take(1) .SelectMany(x => x.Split('\t')) .Select(x => x.Split('=')) .Where(x => x.Length > 1) .ToDictionary(x => x[0].Trim(), x => x[1]); StreamReader reader = new StreamReader(Directory.GetCurrentDirectory() + @"\itemdata.txt"); string content = reader.ReadLine(); reader.Close(); content = Regex.Replace(content, data["item_type"], textitem_type.Text); StreamWriter write = new StreamWriter(Directory.GetCurrentDirectory() + @"\itemdata.txt"); write.WriteLine(content); write.Close(); }

  • PHP issue json_decode echo array

  • exit /B 0 does not work...

    - by murxx
    Hi, I have the following problem: I have created a batch script which calls itself in there (for being able to write a log in parallel). In the script I start another process (like start startServer.bat) which starts up a java process and keeps opened up all the time. In my original script I wait 30 seconds, check if the process is running and do an: exit /B 0 Unfortunately that does not work, the window shows that the exit /B 0 is being evaluated, but the window still keeps open. When I close the window with the other process (meaning the "child" processes started up in my .bat) my script continues its run. So: scriptA.bat - in there I call: start startServer.bat - wait 30 seconds - check is server is started - exit /B 0 Process hangs up! What's very odd, if I wrap another script around, like: scriptB.bat - call scriptA.bat ----- in there I call: start startServer.bat ----- wait 30 seconds ----- check is server is started ----- exit /B 0 - scriptA.bat continues without any hangup! I also tried the same with exit 0 (without /B) also, same result! In the first case it hangs up, in the second case my window closes as expected... Has anyone of you ever had such a problem before and knows what's wrong here? Process hangs up!

  • How to copy files without slowing down my app?

    - by Kevin Gebhardt
    I have a bunch of little files in my assets which need to be copied to the SD-card on the first start of my App. The copy code i got from here placed in an IntentService works like a charm. However, when I start to copy many litte files, the whole app gets increddible slow (I'm not really sure why by the way), which is a really bad experience for the user on first start. As I realised other apps running normal in that time, I tried to start a child process for the service, which didn't work, as I can't acess my assets from another process as far as I understood. Has anybody out there an idea how a) to copy the files without blocking my app b) to get through to my assets from a private process (process=":myOtherProcess" in Manifest) or c) solve the problem in a complete different way Edit: To make this clearer: The copying allready takes place in a seperate thread (started automaticaly by IntentService). The problem is not to separate the task of copying but that the copying in a dedicated thread somehow affects the rest of the app (e.g. blocking to many app-specific resources?) but not other apps (so it's not blocking the whole CPU or someting) Edit2: Problem solved, it turns out, there wasn't really a problem. See my answer below.

  • What does a DependencyReplicator.xml file look like?

    I am trying to get started using Dependency Replicator http://www.codeplex.com/tfsdepreplicator. There is no documentation in place and therefore no example of a DependencyReplicator.xml file which I need in order to take my experiment further.
