S3 file Uploading from Mac app though PHP?

- by Ilija Tovilo

I have asked this question before, but it was deleted due too little information. I'll try to be more concrete this time. I have an Objective-C mac application, which should allow users to upload files to S3-storage. The s3 storage is mine, the users don't have an Amazon account. Until now, the files were uploaded directly to the amazon servers. After thinking some more about it, it wasn't really a great concept, regarding security and flexibility. I want to add a server in between. The user should authenticate with my server, the server would open a session if the authentication was successful, and the file-sharing could begin. Now my question. I want to upload the files to S3. One option would be to make a POST-request and wait until the server would receive the file. Problems here are, that there would be a delay, when the file is being uploaded from my server to the S3 servers, and it would double the uploading time. Best would be, if I could validate the request, and then redirecting it, so the client uploads it directly to the s3-storage. Not sure if this is possible somehow. Uploading directly to S3 doesn't seem to be very smart. After looking into other apps like Droplr and Dropmark, it looks like they don't do this. Btw. I did this using Little Snitch. They have their api on their own web-server, and that's it. Could someone clear things up for me? EDIT How should I transmit my files to S3? Is there a way to "forward" it, or do I have to upload it to my server and then upload it from there to S3? Like I said, other apps can do this efficiently and without the need of communicating with S3 directly.

C#; On casting to the SAME class that came from another assembly

- by G. Stoynev

For complete separation/decoupling, I've implemented a DAL in an assebly that is simply being copied over via post-build event to the website BIN folder. The website then on Application Start loads that assembly via System.Reflection.Assembly.LoadFile. Again, using reflection, I construct a couple of instances from classes in that assembly. I then store a reference to these instances in the session (HttpContext.Current.Items) Later, when I try to get the object stored in the session, I am not able to cast them to their own types (was trying interfaces initially, but for debugging tried to cast to THEIR OWN TYPES), getting this error: [A]DAL_QSYSCamper.NHibernateSessionBuilder cannot be cast to [B] DAL_QSYSCamper.NHibernateSessionBuilder. Type A originates from 'DAL_QSYSCamper, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' in the context 'Default' at location 'C:\Users\dull.anomal\AppData\Local\Temp\Temporary ASP.NET Files\root\ad6e8bff\70fa2384\assembly\dl3\aaf7a5b0\84f01b09_b10acb01\DAL_QSYSCamper.DLL'. Type B originates from 'DAL_QSYSCamper, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' in the context 'LoadNeither' at location 'C:\Users\dull.anomal\Documents\Projects\QSYS\Deleteme\UI\MVCClient\bin\DAL_QSYSCa mper.DLL'. This is happening while debugging in VS - VS manages to stop into the source DAL project even though I've loaded from assembly and the project is not refferenced by the website project (they're both in the solution). I do understand the error, but I don't understand how and why the assembly is being used/loaded from two locations - I only load it once from the file and there's no referrence to the project. Should mention that I also use Windsor for DI. The object that tries to extract the object from the session is A) from a class from that DAL assembly; B) is injected into a website class by Windsor. I will work on adding some sample code to this question, but wanted to put it out in case it's obvious what I do wrong.

Specifying SOAP Headers for a Zend_Soap Service

- by Stephen

I have a generally straight forward web service that I've written (converting code to ZF from a Java implementation of the same service and trying to maintain the same wsdl structure as much as possible). The service loads a PHP class, rather than individual functions. The PHP class contains three different functions within it. Everything seems to be working just fine, except that I can't seem to figure out how to specify that a given function parameter should be passed as a SOAP header. I've not seen any mention of SOAP headers in the Server context, only how to pass header parameters with a client to a server. In addition to the standard parameters for the function that would be sent in the SOAP body and detailed in the docblock, I would like to specify two parameters (a username and password) that would be sent in a SOAP header. I have to assume this is possible, but haven't been able to find anything online, nor have I had any responses to a similar post on Zend's forum. Is there something that can be added in the docblock area to specify a parameter as a header (maybe in a similar fashion to using WebParam?)? Any suggestions/examples on how to get this accomplished would be greatly appreciated!

SIlverlight Navigate: how does it work? How would you implement in f# w/o VS wizards and helpers?

- by akaphenom

After a nights sleep the problem can be stated more accurately as I have a 100% f# / silverlight implementation and am looking to use the built in Navigation components. C# creates page.xaml and page.xaml.cs um - ok; but what is the relationship at a fundamental level? How would I go about doing this in f#? The applcuation is loaded in the default module, and I pull the XAML in and reference it from the application object. Do I need to create instances / references to the pages from within the application object? Or set up some other page management object with the proper name value pairs? When all the Help of VS is stripped away - what are we left with? original post (for those who may be reading replies) I have a 100% silverlight 3.0 / f# 2.0 application I am wrapping my brain around. I have the base application loading correctly - and now I want to add the naigation controls to it. My page is stored as an embedded resource - but the Frame.Navigate takes a URI. I know what I have is wrong but here it is: let nav : Frame = mainGrid ? mainFrame let url = "/page1.xaml" let uri = new System.Uri(url, System.UriKind.Relative) ; nav.Navigate uri Any thoughts?

Server side aggregation using Spring MVC Controllers

- by Venu

Hi! We have a web site with multiple pages each with lot of AJAX calls. All the Ajax calls go to a data proxy layer written in Spring 3 MVC application. In order to reduce the load on the server we are planning to aggregate calls on the client and send to the proxy layer. For ex: we have two calls /controller1/action1 and /controller2/action2 in different controllers. I want to write an aggregate controller and call it from the client instead of making two calls to the individual controllers. Something like /aggregatecontroller/aggregate (and we will post the information regarding which calls are being aggregated and required parameters). Is there any way we can call another controller/action from a controller/action and get output? The flow will be something like this: a. Call /aggregatecontroller/aggregate with info regd call1 and call2 b. aggregate action understands that it needs to aggregate call1 and call2 c. it calls /controller1/action1 and gets the response d. it calls /controller2/action2 and gets the response e. it merges both in a json response and sends it back to browser. Please let me know if you have any suggestion regd how to do this or if you think there is a better approach to do the server side aggregation. Thanks for your time.

Java string to double conversion.

- by wretrOvian

Hi, I've been reading up on the net about the issues with handling float and double types in java. Unfortunately, the image is still not clear. Hence, i'm asking here direct. :( My MySQL table has various DECIMAL(m,d) columns. The m may range from 5 to 30. d stays a constant at 2. Question 1. What equivalent data-type should i be using in Java to work (i.e store, retrieve, and process) with the size of the values in my table? (I've settled with double - hence this post). Question 2. While trying to parse a double from a string, i'm getting errors Double dpu = new Double(dpuField.getText()); for example - "1" -> java.lang.NumberFormatException: empty String "10" -> 1.0 "101" -> 10.0 "101." -> 101.0 "101.1" -> 101.0 "101.19" -> 101.1 What am i doing wrong? What is the correct way to convert a string to a double value? And what measures should i take to perform operations on such values?

Cross-browser method for getting width and height of a DIV?

- by thinkthank

This is my first post, so please go easy on me. I'm sure I'm doing everything wrong. However, I couldn't find any posts that answered the question above. I use jQuery. I'm trying to find a way to get the current width and height of a DIV element, even if they're set to "auto". I've found many ways to do this, but no method returns the same width in IE. It is important that this method is cross-browser, as it will break the layout of the page if different numbers are returned in different browsers. .width() and .height() do not work because in IE, padding is subtracted (e.g. width() returns 25 where width is 30 and padding is 5). .outerWidth() and .outerHeight() are not consistent either. While they work IE (believe it or not) in FF, the padding is added again to the full width (e.g. outerWidth() returns 110 in FF where width is 100px and padding is 10px). Is there any way out of this mess without writing complex browser checks? Thanks!

Invalid Argument javascript error only on certain computers

- by Jen

Getting an error whenever we click a particular button/link on our site. It is generating a javascript "Invalid Argument" error. I know in the other posts it is typically because it is a syntax error in the javascript however it only just seems to have started happening and it doesn't happen on all pcs. ie. in our client's environment if I remote onto their web server and view the uat website I get the javascript error. If I remote onto their sql server and view the uat website I don't get the javascript error. If it was a syntax error then I would always get the error wouldn't I? both browsers are the same version of IE6 (yeah I know...) :) I have tried deleting temporary internet files - including viewing the files and deleting them myself - but no joy. client uses citrix.. and they're all getting the error :( Any ideas would be appreciated - Thanks! :) Update - Sorry I haven't posted specific code as there is too much to post (and I'm not sure where the error is occurring). The "button" launches a new window which in turn opens up a couple of aspx pages and calls lots of javascript. So the window opens ok, and there's a function that gets called to resize the window - but before it calls the resizing of the window/content it throws the invalid argument error. Am busy trying to get alerts to trigger to see if I can see where it's falling over but so far no luck. Again not sure why this error doesn't occur when I use a particular PC (same browser version)

S.redirectTo leads always to a blank screen

- by Jaime Ocampo

I am now playing a little bit with lift (2.8.0), and all the features in LiftRules work as intended. But I haven't been able to use S.redirectTo at all. I always ends with a blank screen, no matter what. No error messages at all! As an example, I have the following form: ... <lift:logIn.logInForm form="post"> <p><login:name /></p> <p><login:password /></p> <p><login:submit /></p> </lift:logIn.logInForm> ... And the code is: object LogIn extends helper.LogHelper { ... def logInForm(in: NodeSeq): NodeSeq = { var name = "" var password = "" def login() = { logger.info("name: " + name) logger.info("password: " + password) if (name == "test1") S.redirectTo("/example") if (name == "test2") S.redirectTo("/example.html") if (name == "test3") S.redirectTo("example.html") S.redirectTo("/") } bind("login", in, "name" -> SHtml.text(name, name = _), "password" -> SHtml.password(password, password = _), "submit" -> SHtml.submit("Login", login)) } } The method 'login' is invoked, I can check that in the log information. But as I said, no matter which name I enter, I always end with a blank screen, although 'examples.html' is available when being accessed directly in the browser. How should I invoke S.redirectoTo in order to navigate to 'examples.html'? Also, why don't I receive an error message (I am logging at a debug level)? I think all the configuration in Boot is correct, since all LitRules examples (statelessRewrite, dispatch, viewDispatch, snippets) work fine.

how to run the async task at specific time? (I want to run it every 2 mins) I tried using post delayed but it's not working? tvData.postDelayed(new Runnable(){ @Override public void run() { readWebpage(); }}, 100); In the above code readwebpage is function which calls the async task for me.. Right now below is the method which I am using public void onCreate(Bundle savedInstanceState) { readwebapage(); } public void readWebpage() { DownloadWebPageTask task = new DownloadWebPageTask(); task.execute("http://www.google.com"); } private class DownloadWebPageTask extends AsyncTask<String, Void, String> { @Override protected String doInBackground(String... urls) { String response1 = ""; response1=read(); //read is my another function which does the real work response1=read(); super.onPostExecute(response1); return response1; } protected void onPostExecute(String result) { try { Thread.sleep(100); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } TextView tvData = (TextView) findViewById(R.id.TextView01); tvData.setText(result); DownloadWebPageTask task = new DownloadWebPageTask(); task.execute(new String[] { "http://www.google.com" }); } } This is what I my code is and it works perfectly fine but the big problem I drains my battery?

Autoscale Font in a TextBox Control so that its as big as possible and still fits in text area bound

- by blak3r

I need a TextBox or some type of Multi-Line Label control which will automatically adjust the font-size to make it as large as possible and yet have the entire message fit inside the bounds of the text area. I wanted to see if anyone had implemented a user control like this before developing my own. Example application: have a TextBox which will be half of the area on a windows form. When a message comes in which is will be approximately 100-500 characters it will put all the text in the control and set the font as large as possible. An implementation which uses Mono Supported .NET libraries would be a plus. Thanks in advance. If know one has implemented a control already... If someone knows how to test if a given text completely fits inside the text area that would be useful for if I roll my own control. Edit: I ended up writing an extension to RichTextBox. I will post my code shortly once i've verified that all the kinks are worked out.

ajax call success function never called

The following code is a very simple ajax call to server that alerts back on success and complete events. From a reason I cannot understand on my development machine it works fins and alerts on success and complete but on server it never alerts on success. WHY ??? ** <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> <script src="Scripts/jquery-1.7.1.min.js" type="text/javascript"></script> <script type="text/javascript"> function dummy() { $.ajax({ url: 'services/chatEngine.asmx/dummy', async: true, type: "POST", complete: function () { alert('Done'); }, success: function (a, b, c) { alert('Success'); } }); } </script> </head> <body> <form id="form1" runat="server"> <div> <ajaxToolkit:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server"> </ajaxToolkit:ToolkitScriptManager> <div id="userList">Users:<br /></div> <input id="Button3" type="button" value="dummy" onclick="dummy()" /> </div> </form> </body> </html> ** The server side dummy function returns nothing, code follows - Public Function dummy() As String Return "" End Function

Wrapper background image gets cut off at the top

- by dq7133

My site has a wrapper with three background images. A static top and bottom image and a third image that repeats along the y axis. For some reason the top background image is getting cut off and I can't figure out way. Here is a link to the live site: http://storrepictures.weebly.com/projects.html I have offset the top and bottom images so you can see what they look like. You can see that the top one is cut off. I've tried messing around with some of the div padding settings but can't seem to get it to work. One interesting note: The background images used to be JPEGs (I switched to PNG files because I needed transparency). When I was using JPEGs this was not a problem - the three images lined up perfectly. Let me know if it would help to have the actual code posted. From what I've been reading on this forum, people seem to like looking at the live site and I didn't want to make the post too long. Thanks a lot for all your help.

Short snippet summarizing a webpage?

- by Legend

Is there a clean way of grabbing the first few lines of a given link that summarizes that link? I have seen this being done in some online bookmarking applications but have no clue on how they were implemented. For instance, if I give this link, I should be able to get a summary which is roughly like: I'll admit it, I was intimidated by MapReduce. I'd tried to read explanations of it, but even the wonderful Joel Spolsky left me scratching my head. So I plowed ahead trying to build decent pipelines to process massive amounts of data Nothing complex at first sight but grabbing these is the challenging part. Just the first few lines of the actual post should be fine. Should I just use a raw approach of grabbing the entire html and parsing the meta tags or something fancy like that (which obviously and unfortunately is not generalizable to every link out there) or is there a smarter way to achieve this? Any suggestions? Update: I just found InstaPaper do this but am not sure if it is getting the information from RSS feeds or some other way.

Overriding Code Igniter 2.14's global_xss_filtering settting

- by user2353007

I have created the following file at: application/core/MY_Security.php <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed'); /* * Does not work with global xss */ class MY_Security extends CI_Security { function xss_clean($str, $is_image = FALSE) { $CI =& get_instance(); $CI->load->library('My_cleaner'); return $CI->my_cleaner->clean_html($str); } } this works great for $this-input-post('post_var', TRUE); and $this-security-xss_clean($input); It is working very well except when I go into application/config/config.php and change $config['global_xss_filtering] = FALSE; to $config['global_xss_filtering] = TRUE; in that case, I just get a white page on every controllers action/function. Does anybody know what else I have to change to get global_xss_filtering = TRUE; to work when overriding the xss_clean function in system/core/Security.php through application/core/MY_Security.php? I'm guessing it might be something with the loader but I'm not sure where to start. The next option is to just replace the function in the system/core/Security.php file which I am trying to avoid. Thanks.

Please help with IFrame callback

- by Code Sherpa

Hi - thanks for clicking. I am trying to get status feedback using an IFrame for file uploads. I am not trying to get progress or percentages - just when a file is done uploading and if it was a success or failure. THE PROBLEM is that I can't seem to get the server response to appear on the client. I have to following design: I have an iframe on my page: <iframe id="target_frame" src="" style="border:0px; width:0px; height:0px"></iframe> The form tag points to it: <form enctype="multipart/form-data" id="fileUploadForm" name="fileUploadForm" action="picupload.aspx" method="post" target="target_frame"> And the submit button starts a file upload via the iframe: <input id="submit" type="submit" value="upload" /> In the picupload.aspx.cs file, I have a method that returns dynamic data. I then send it to the client: message = data; Response.Write(String.Format("<script language='javascript' type='text/javascript'>window.parent.handleResponse('{0}');</script>", message)); On the client, I have a response handler: function handleResponse(msg) { document.getElementById('statusDiv').innerHTML = msg; } My intent is to see the msg value change for each uploaded file but I never see anything appear in statusDiv, let alone dynamically changing messages. Can somebody please help??

download file, without saving in server

Hi, Or possible for users to download the file without saving it on the server? I am getting data from the database, and I want to save them .doc (MS Word) file. if(isset($_POST['save'])) { $file = "new_file2.doc"; $stringData = "Text text text text...."; //This data put in new Word file $fh = fopen($file, 'w'); fwrite($fh, $stringData); fclose($fh); header('Content-Description: File Transfer'); header('Content-type: application/msword'); header('Content-Disposition: attachment; filename="'.$file.'"'); header('Content-Transfer-Encoding: binary'); header('Expires: 0'); header('Cache-Control: must-revalidate, post-check=0, pre-check=0'); header('Pragma: public'); header('Content-Length: ' . filesize($file)); ob_clean(); flush(); readfile($file); unlink($file); exit; } How should the code look like without this: " $fh = fopen($file, 'w'); fwrite($fh, $stringData); fclose($fh);" and this "unlink($file);" I hope to understand what I need enter code here
