  • What is the easiest way to get an embedded upload progress bar using Ruby/Sinatra/Haml/Passenger/ngi

    - by mmr
    I have a website where people can upload 30+mb of data in a single block, and I want to be able to show them the progress of their upload without causing the web page to become unresponsive, similar to how flash uploads work in gmail. There's this question here, but I don't know if that progress bar is embedded in the page or if it's using the browser's progress bar. I'm also a bit of a web newb, so I'm not sure if it's the 'easiest'. I asked the swfupload guys how to do this here, and the answer I got is 'this tool requires some knowledge to use it' without giving me much help in figuring out where to get started. I also asked this question on ServerFault, and got no response, so maybe that was the wrong place to ask. I'm all for learning new things and so forth, but there are a lot of potential pathways to take here. Where should I start, and what do I need to know to make everything work with sinatra, haml, ruby, passenger, and nginx? Thanks!

  • WebClient DownloadStringCompleted Never Fired in Console Application

  • Del.icio.us get xml of all posts

    - by Marvin
    Im trying to get all of my posts in a delicious account to an MySql DB. Since delicious exports xml I think it wont be too complicated, but being new to it I cant really make sense of the api... I believe I have to query it as so: https://api.del.icio.us/v1/posts/all? But one catch is that im using an yahoo id for that account which I need to do it as follows: "To access data from accounts created using a Yahoo! ID, use the same API's as below, but change the path to /v2, and make HTTP requests using OAuth as provided by the Yahoo! Developer Network." I cant understand how to do it, can someone please help. Thanks. EDIT Although I still have the same doubt I figured out I can export the whole thing from the settings in my account, now I just need to get the html export in a xml file :) Also the yahoo method for accessing data, really is no good.

  • free geolocation geoip, are they viable?

    - by brett
    I'm trying to get a visitor's location based on their IP, pretty common stuff. My research so far shows that there's a database from MaxMind that costs $370 + $90/month... not the type of cost I can afford. Then there's a free version called GeoLite City. Anyone used these before? Drop a quick line here please. Why is one free and the answer so expensive. Is the free one usable, is it not as accurate, what's the catch? P.S. Any other suggestions are welcome.

  • Does throwing an exception in an EvalFunc pig UDF skip just that line, or stop completely?

    - by Daniel Huckstep
    I have a User Defined Function (UDF) written in Java to parse lines in a log file and return information back to pig, so it can do all the processing. It looks something like this: public abstract class Foo extends EvalFunc<Tuple> { public Foo() { super(); } public Tuple exec(Tuple input) throws IOException { try { // do stuff with input } catch (Exception e) { throw WrappedIOException.wrap("Error with line", e); } } } My question is: if it throws the IOException, will it stop completely, or will it return results for the rest of the lines that don't throw an exception? Example: I run this in pig REGISTER myjar.jar DEFINE Extractor com.namespace.Extractor(); logs = LOAD '$IN' USING TextLoader AS (line: chararray); events = FOREACH logs GENERATE FLATTEN(Extractor(line)); With this input: 1.5 7 "Valid Line" 1.3 gghyhtt Inv"alid line"" I throw an exceptioN!! 1.8 10 "Valid Line 2" Will it process the two lines and will 'logs' have 2 tuples, or will it just die in a fire?

  • Problem reading from the StandarOutput from ftp.exe. Possible System.Diagnostics.Process Framework b

    - by SoMoS
    Hello, I was trying some stuff executing console applications when I found this problem handling the I/O of the ftp.exe command that everybody has into the computer. Just try this code: m_process = New Diagnostics.Process() m_process.StartInfo.FileName = "ftp.exe" m_process.StartInfo.CreateNoWindow = True m_process.StartInfo.RedirectStandardInput = True m_process.StartInfo.RedirectStandardOutput = True m_process.StartInfo.UseShellExecute = False m_process.Start() m_process.StandardInput.AutoFlush = True m_process.StandardInput.WriteLine("help") MsgBox(m_process.StandardOutput.ReadLine()) MsgBox(m_process.StandardOutput.ReadLine()) MsgBox(m_process.StandardOutput.ReadLine()) MsgBox(m_process.StandardOutput.ReadLine()) This should show you the text that ftp sends you when you do that from the command line: Los comandos se pueden abreviar. Comandos: ! delete literal prompt send ? debug ls put status append dir mdelete pwd trace ascii disconnect mdir quit type bell get mget quote user binary glob mkdir recv verbose bye hash mls remotehelp cd help mput rename close lcd open rmdir Instead of that I'm getting the first line and 3 more with garbage, after that the call to ReadLine block like if there was no data available. Any hints about that?

  • MVC - Calling Controller Methods

    - by JT703
    Hello, My application is following the MVC design pattern. The problem I keep running into is needing to call methods inside a Controller class from outside that Controller class (ex. A View class wants to call a Controller method, or a Manager class wants to call a Controller method). Is calling Controller methods in this way allowed in MVC? If it's allowed, what's the proper way to do it? According to the version of MVC that I am following (there seems to be so many different versions out there), the View knows of the Model, and the Controller knows of the View. Doing it this way, I can't access the controller. Here's the best site I've found and the one describing the version of MVC I'm following: http://leepoint.net/notes-java/GUI/structure/40mvc.html. The Main Program code block really shows how this works. Thanks for any answers.

  • How to specify argument attributes in CFscript? (CF9)

    - by Henry
    In CF9 doc: Defining components and functions in CFScript, it says: /** *Comment text, treated as a hint. *Set metadata, including, optionally, attributes, in the last entries *in the comment block, as follows: *@metadataName metadataValue ... */ access returnType function functionName(arg1Type arg1Name="defaultValue1" arg1Attribute="attributeValue...,arg2Type arg2Name="defaultValue2" arg2Attribute="attributeValue...,...) functionAttributeName="attributeValue" ... { body contents } How do you specify arg1Attribute? I tried this: public void function setFirstname(string firstname="" displayName="first name"){} but it does NOT work. Also, how do you translate this to script-style? <cffunction name="setPerson"> <cfargument name="person" type="com.Person"/> </cffunction> I tried: function setPerson(com.Person person){} and it does NOT work either. "You cannot use a variable reference with "." operators in this context" it says.

  • I am having trouble using FileReader to write a txt file to an array (Java), what am I doing wrong?

    - by deliriumtremens
    Scanner s = null; try { s = new Scanner(new BufferedReader(new FileReader("rates.txt"))); for (int i=0; i<9; i++){ while(s.hasNext()){rates[i] = s.next();} System.out.println(rates[i]); } }catch (IOException e){ System.out.println(e); } finally { if (s != null) { s.close(); } } When I run this code, it reads the last chunk of characters in my txt file, places them in rates[0], sticks null in 1-8, then puts that same last chunk in rates[9]. I'm not sure why it's reading the end of my file first. The contents of the txt are below.. USD 1.34 EUR 1.00 JPY 126.28 GBP 0.88 INR 60.20 It reads the 60.20, which is all it is recording in the array. Any help would be appreciated.

  • computing "node closure" of graph with removal

    - by Fakrudeen
    Given a directed graph, the goal is to combine the node with the nodes it is pointing to and come up with minimum number of these [lets give the name] super nodes. The catch is once you combine the nodes you can't use those nodes again. [first node as well as all the combined nodes - that is all the members of one super node] The greedy approach would be to pick the node with maximum out degree and combine that node with nodes it is pointing to and remove all of them. Do this every time with the nodes which are not removed yet from graph. The greedy is O(V), but this won't necessarily output minimum number super nodes. So what is the best algorithm to do this?

  • How to obtain the native stacktrace from native exceptions caught in managed code

    - by aaa
    I have some managed code that calls to a method inside some native DLL(i have the appropriate symbol files). Sometimes, that native method throws an exception which I catch in my managed code. However, when i print the stacktrace from my caught exception, I see only managed code (the last frame is the call to the native code .. but it don't see the stacktrack within the native code). How can I obtain the native callstack as well? *When i'm debugging the code, i am able to step into the native code, and see the actuall call stack.

  • Marshaling an array of IntPtrs in C#

    - by mcoolbeth
    From safe, managed code in C#, I would like to call a function in a C API that receives an array of pointers (void**). I have the corresponding managed array of IntPtr objects, but the Marshal methods advertised in the documentation at MSDN do not seem sufficient to provide and IntPtr to an unmanaged block of memory with the correct content. I had hoped to obtain an IntPtr with 'Marshal.AllocHGlobal' and then assign the correct content using 'Marshal.Copy', but it seems the function has not been overloaded for an array of IntPtr. Any thoughts on the best way to do this? Thanks in advance.

  • What does msvc 6 throw when an integer divide by zero occurs?

    - by EvilTeach
    I have been doing a bit of experimenting, and have discovered that an exception is being thrown, when an integer divide by zero occurs. #include <iostream> #include <stdexcept> using namespace std; int main ( void ) { try { int x = 3; int y = 0; int z = x / y; cout << "Didn't throw or signal" << endl; } catch (std::exception &e) { cout << "Caught exception " << e.what() << endl; } return 0; } Clearly it is not throwing a std::exception. What else might it be throwing?

    Hi, I am using the flex datagrid to allow the user to edit some data. My update process relies on a CollectionEvent of type update. Basically I catch this event package the values and update the database. However, if the user edits a cell then moves to edit a cell in the same row the value is updated but a collection event is not fired. Only when clicking out of the row the event is fired. Has anyone had experience with this. I have heard the datagrid is a little quirky is this one of those quirks or am I doing this all wrong? Any help appreciated.

  • SVN post commit stucks while starting process

    - by Oded
    Hi, I've built a script in VS that receives the 2 arguments sent by post-commit hook. The script runs SVN LOG to retrieve data about the revision (author, date, files). When I run the solution from VS with constant vars for the arguments, it runs perfectly. When I execute the exe file, also runs perfectly. When I implement the hook script, it fails where it should read from the process. process.Start(); process.WaitForExit(); str = process.StandardOutput.ReadToEnd(); process.WaitForExit(); if (!process.HasExited) { try { process.Kill(); } catch (Exception e3) { // process is terminated } // Write Errors } Thanks. EDIT: The commit window stucks and never completes the commit. I write the code in C#.... there is no errors shown...

  • HTML + CSS dynamic render in flash?

    - by Ole Jak
    I have HTML + CSS text. I need some lib with simple function like "Render String Var conteining HTML" So no external files (like in flash lib called HTMLwraper you just have to play your SWF on top of HTML). dinamic! I give it string it renders It into some conteiner (not as a bitmab but as if it was real HTML dynamically rendered in flash). (And I need real HTML + CSS support not what normal rich text block gives us) I am going to use it in with Flex (Flash Builder) so I like MXML component model but even pure flash AS3 will workout. It should be Free and Opensource (any license like GPL, LGPL etc will be ok). So Is out there such flash\flex library for HTML + CSS dynamic rendering (rfom given String or XML)?

  • 100% width bg images not extending on horizontal scroll

    - by Fuego DeBassi
    I'm noticing this issue. I made a quick screen capture to demonstrate: http://dl.dropbox.com/u/904456/2010-06-14_2323.swf Basically when you have a min-width set and the viewport goes under that constraint, a horizontal scroll bar appears. Pretty much what you would expect, but when you scroll over horizontally all elements that are suppose to extend across the entire width of the page and have background images/colors different from the body do not extend. If you resize the viewport it seems to catch up. Is this a known issue? You can see it on a lot of sites, http://gowalla.com for example. Any ideas?

  • Send custom headers with UIWebView loadRequest

    - by Thomas Clayson
    I want to be able to send some extra headers with my UIWebView loadRequest method. I have tried: NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://www.reliply.org/tools/requestheaders.php"]]; [req addValue:@"hello" forHTTPHeaderField:@"aHeader"]; [self.theWebView loadRequest:req]; I have also tried subclassing the UIWebView and intercepting the - (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType method. In that method I had a block of code which looked like this: NSMutableURLRequest *newRequest = [request mutableCopy]; for(NSString *key in [customHeaders allKeys]) { [newRequest setValue:[customHeaders valueForKey:key] forHTTPHeaderField:key]; } [self loadRequest:newRequest]; But for some unknown reason it was causing the web view to not load anything (blank frame) and the error message NSURLErrorCancelled (-999) comes up (all known fixes don't fix it for me). So I am at a loss as to what to do. How can I send a custom header along with a UIWebView request? Many thanks!
