• Android ListView Item Visibility

  - by user1478754

  I'm trying to create a screen that displays multiples items. For this, I've created a listview but I'm not sure how to approach how to add/remove items from it. Since I'm using custom listview items, I've created my own listadapter but now I need a way to add items on a button click. Is there a way to create listview that can take an indefinite amount of items (instead of passing it in an fixed length array of View objects)? Also what's the best way to remove items from listviews? setVisibility?

• Strange Array#each Ruby behaviour

  - by with a dot.

  The question is a bit vague, but I am not really sure why this happens: I have the following code: p user.room.users.length user.room.users.each {|usr| puts "b" } user.room.users.each {|usr| puts "a"; usr.enter(Room[Config::entrance]) } which outputs: 5 b b b b b a a a I also made User#enter count how many times it's been called and it returns 3! I am completely baffled by this behaviour. I doubt the code within User#enter is the cause, but if someone thinks it might be relevant I can provide it (I don't want to clutter the question unnecessarily). Edit If it's relevant I am using ruby-1.9.3-p125

• Efficient retrieval of lists over WebServices

  - by Chris

  I have a WCF WebService that uses LINQ and EF to connect to an SQL database. I have an ASP.NET MVC front end that collects its data from the webservice. It currently has functions such as List<Customer> GetCustomers(); As the number of customers increases massively the amount of data being passed increases also reducing efficiency. What is the best way to "page data" across WebServices etc. My current idea is to implement a crude paging system such as List<Customer> GetCustomers(int start, int length); This, however, means I would have to replicate such code for all functions returning List types. It is unfortunate that I cannot use LINQ as it would be much nicer. Does anyone have any advice or ideas of patterns to implement that would be "as nice as possible" Thanks

• R scatterplot overplotting color

  - by rgeekay

  So far I have this: qplot(df[[1]], as.numeric(rownames(df)), group=df[[2]], color=df[[2]], ylab="") I want to use different colors for the points in the 2 groups - perhaps a lighter shade for the what's in black now and a darker - say, red for what's in blue. Also, I want to use hexbin kind of thing for group=0 but not for group=1. I'm not able to get the syntax to get this working. In the current plot 0 is in black and 1 is in blue. Added: I worked on it some more, and by using factor and scale_colour_manual, I got the grey color for 0 and red for 1: > palette1 [1] "grey" "red" "blue" "violet" "black" fy=factor(y, labels=c('grey', 'red')) qplot(x, seq(1:length(x)),col=fy, ylab="") + geom_point() + scale_colour_manual(values=palette1) Pending questions are: How to first plot all the grey and then red on top (some of the red is now hidden because the grey is plotted over). How to apply the hexbin logic for group0 i.e. the grey points only and not for the red.

• networkstream always empty!

  - by ALEX

  hey I'm writing on an Server-Client program but when my client sends something, it never reaches my server! I'm sending like this: public void Send(string s) { char[] chars = s.ToCharArray(); byte[] bytes = chars.CharToByte(); nstream.Write(bytes, 0, bytes.Length); nstream.Flush(); } and Receiving in a background thread like this void CheckIncoming(object dd) { RecievedDelegate d = (RecievedDelegate)dd; try { while (true) { List<byte> bytelist = new List<byte>(); System.Threading.Thread.Sleep(1000); int ssss; ssss = nstream.ReadByte(); if (ssss > 1) { System.Diagnostics.Debugger.Break(); } if (bytelist.Count != 0) { d.Invoke(bytelist.ToArray()); } } } catch (Exception exp) { MSGBOX("ERROR:\n" + exp.Message); } } the ssss int is never 1 whats happening here???

• Compare images to find differences

  - by _simon_

  Task: I have a camera mounted on the end of our assembly line, which captures images of produced items. Let's for example say, that we produce tickets (with some text and pictures on them). So every produced ticket is photographed and saved to disk as image. Now I would like to check these saved images for anomalies (i.e. compare them to an image (a template), which is OK). So if there is a problem with a ticket on our assembly line (missing picture, a stain,...), my application should find it (because its image differs too much from my template). Question: What is the easiest way to compare pictures and find differences between them? Do I need to write my own methods, or can I use existing ones? It would be great if I just set a tolerance value (i.e. images can differ for 1%), put both images in a function and get a return value of true or false :) Tools: C# or VB.NET, Emgu.CV (.NET wrapper for OpenCV) or something similar

• How to identify/handle text file newlines in Java?

  - by rafrafUk

  Hi Everyone! I get files in different formats coming from different systems that I need to import into our database. Part of the import process it to check the line length to make sure the format is correct. We seem to be having issues with files coming from UNIX systems where one character is added. I suspect this is due to the return carriage being encoded differently on UNIX and windows platform. Is there a way to detect on which file system a file was created, other than checking the last character on the line? Or maybe a way of reading the files as text and not binary which I suspect is the issue? Thanks Guys !

• .Net MVC - Restful URL's - The specified path, file name, or both are too long. The fully qualified

  - by Truegilly

  Hello, im creating a MVC application thats following a restfull URL approach Im am experiencing the following error... "The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters." This error occurs when my URL length = 225 chars. Surly I can have much longer URL's without this problem and doesn’t this relate to file paths rather than URL's ? Im sure some of you MVC guys have experienced this ;) is there a way round it ?? where am i going wrong ?? thank you for your time Truegilly

• How to track when my application has unexpectedly shut down?

  - by Vilx-

  I'm writing an application whose purpose involves a lot of logging of different events. Among those I would also like to have an event that the application was shut down - even if unexpectedly like because of a power loss. Naturally, when the power goes out I don't get a chance to write anything anywhere. So my idea was to continuously write a timestamp in some known location (say, once per minute), and when the application was next run, it could determine the approximate time of the unexpected shutdown. A precision of 1 minute would be acceptable for me. However I'm worried that caching at the OS and disk level might interfere with this approach. Is there a better way or if not - how to make sure that the data I just wrote is REALLY written out to the physical medium? Added: Oh, almost forgot the buzzword line: Windows XP and above; .NET 3.5; C#.

• Only strip commas surrounded by numbers in a string

  - by overlook77

  I am using StreamReader to read each line of a CSV file into a string. As I am processing each line, I need to strip out any commas that ONLY are surrounded by other numbers. For example, if the string was: "textfield1", "textfield2", "100.00", "1,070.00" I would need to only take the comma out of "1,070.00" from this entire string, resulting in: "textfield1", "textfield2", "100.00", "1070.00" Each string read from the CSV file can differ in number of fields, length, etc., so I need to use something (Regular Expressions maybe?) that looks at the entire string without hardcoding a location or blanket removal of all commas. Here is the approach I have been trying: StreamReader sr = new StreamReader(strInputFile); string nextLine = sr.ReadLine(); try { while ((nextLine = sr.ReadLine()) != null) { string rawtext = nextLine.Replace("[0-9]"+","+"[0-9]" , "[0-9]"+"[0-9]"); // ....rest of code } } This obviously doesn't work because I don't understand how to do this :) I am new at C# and inexperienced in Regex, so hopefully this is relatively simple.

• How can I format numbers as money in JavaScript?

  - by Daniel Magliola

  I would like to format a price in JavaScript. Basically, I have a float variable, and I'd like to have a function that will receive that variable, and output: "$ 2,500.00" What's the best way to do this? EDIT: OK, since I haven't gotten any answers better than the code I implemented, plus my own answer has been voted down and I can't put my own answer as the right one... Here it is... var DecimalSeparator = Number("1.2").toLocaleString().substr(1,1); var AmountWithCommas = Amount.toLocaleString(); var arParts = String(AmountWithCommas).split(DecimalSeparator); var intPart = arParts[0]; var decPart = (arParts.length > 1 ? arParts[1] : ''); decPart = (decPart + '00').substr(0,2); return '£ ' + intPart + DecimalSeparator + decPart;

• Using regular expressions with Dojo data.fetch?

  - by Dfowj

  I'm trying to use the below code to fetch a regular expression like this /[computer]{3,8}/(what i think is any words containing the letters in computer ranging from 3 to 8 letters long) from a database (which i know is being loaded correctly). When i fetch, i get 10 results, all the same word... "Adenauer" var base = "computer"; var baseRE = '/[' + base + ']{' + this.minLength + ',' + base.length + '}/'; this.dict.fetch({query: {word:baseRE}, onComplete: onLoadWords, onError: function(err) { console.log(err); }}); Any ideas what im doing wrong?

• can not find out if the div element is already set in body in chrome extension

  - by alpham8

  in my chrome extension I got an div, which I will add to the body of the current tab. I am listening to chrome.tabs.onUpdated. If this event is called, I execute a script inside content_scripts. In this function there I´ll wait till the document is ready with jQuery $(document).ready(...). I try to access $("#div").length and sometimes it returns 1 and sometimes 0. It should added to the body, if it´s not already there. For some strange reasons, the onUpdated event is called twice on each page reload. Actually I found no way to check safely if the div was already added.

  - by sajjadlove

• Is it possible to exclude folders from a web application project in vs 2010?

  - by JL

  I had previously asked this question. At the time I was working with VS 2008. To restate the question. I have a web application that generates 1000's of small xml files in a certain directory. I would like to exclude this directory from the web application project in visual studio 2010. With vs 2008 it was not possible. Has anything changed? Besides the general wait for VS to iterate through this directory and add an item in the solution explorer for each file, it also strains my system resources, so I would like to exclude it from the project, but the dir and files need to physically exist on disk, because they are part of the application. Any OOB VS 2010 solutions, or any good workarounds? Thanks Update: This also sums up the issue nicely http://forums.asp.net/t/1179077.aspx

• Rewrite Registry File in Windows

  - by Vulcan Eager

  I have been trying to find a way to "defragment" the registry on my Windows machine. Firstly, does this make sense? Any benefits in doing this? (Not much love on superuser.com) Secondly, I am looking for a way to rewrite the registry using C/C++ with Windows API. Is there a way to read the registry and write it to a new file getting rid of unused bytes along the way? (I might have to write the new file and then boot into another OS/disk before I can overwrite the original... but I am willing to take that risk.)

• Recommand a Perl module to persist a large object for re-use between runs?

  - by Alnitak

  I've got a large XML file, which takes 40+ seconds to parse with XML::Simple. I'd like to be able to cache the resulting parsed object so that on the next run I can just retrieve the parsed object and not reparse the whole file. I've looked at using Data::Dumper but the documentation is a bit lacking on how to store and retrieve its output from disk files. Other classes I've looked at (e.g. Cache::Cache) appear designed for storage of many small objects, not a single large one. Can anyone recommend a module designed for this?

• Getting req.params in order in Express JS

  - by Adam Terlson

  In Express, is there a way to get the arguments passed from the matching route in the order they are defined in the route? I want to be able to apply all the params from the route to another function. The catch is that those parameters are not known up front, so I cannot refer to each parameter by name explicitly. app.get(':first/:second/:third', function (req) { output.apply(this, req.mysteryOrderedArrayOfParams); // Does this exist? }); function output() { for(var i = 0; i < arguments.length; i++) { console.log(arguments[i]); } } Call on GET: "/foo/bar/baz" Desired Output (in this order): foo bar baz

• Simple Communication between 2 instances of application

  - by KyleGobel

  I have a WPF application that can take a few optional command line arguments. This application is also a single instance application (using a mutex to close any instances if one is already open). What I want for it to do though, is if something tries to open the application with some cmd line args, that the application will do what it's suppose to do with those (in my application it opens different dialogs based on the cmd line). What is the easiest way to achieve this? In psedo code here is what i'm looking for protected override void OnStartup(StartupEventArgs e) { bool mutexIsNew; using (System.Threading.Mutex m = new System.Threading.Mutex(true, "MyApplication", out mutexIsNew)) { //if this is not the first instance of the app if (!mutexIsNew) { //if there is some cmd line args if (e.Args.Length > 0) { //send the args to the older instance so it can handle them SendToOtherInstance(e.Args); //shutdown this new instance Application.Current.Shutdown(); } } } base.OnStartup(e); }

• jQuery AJAX & an ASP.NET web service works locally but not remotely

  - by Alex

  Interesting one here. I have an ASP.NET 1.1 project that contains a web service in it. I'm using jQuery's AJAX functionality to call some services from the client. This is what my code looks like: $.ajax({ type: "POST", url: 'foo.asmx/functionName', data: 'foo1=' + foo1 + '&foo2=' + foo2, dataType: "xml", success: function(xml) { //do something with my xml data }, error: function(request, error){ //handle my error } }); This works great when I run the site from my IDE on localhost. However, when I deploy this site to any other server I get a parsererror error from jQuery. It does not appear to even call my service as I dropped in some code to write a log file to disk and it's not making it there. The same exact XML should be returned from both my localhost and the server I deployed to. Any ideas?
