  • Access asp:CheckBox inner input from jQuery

    - by abatishchev
    I have a jQuery array acting on each control having corresponding class: function Foobar() { $('.foo').each(function() { // do something with $(this) } } I can access client-side controls like <input class="foo"> and server-side controls like asp:TextBox CassClass="foo"> But setting CssClass for asp:RadioButton doesn't make a sense. Here is generated code: <span class="foo"> <input type="radio" /> </span> How to set class for inner input or another way gather it using jQuery?

  • Disk IO Performance Limitations based on numbers of folders/files

    - by Josh
    I have an application where users are allowed to upload images to the server. Our Web Server is a windows 2008 server and we have a site (images.mysite.com) that points to a shared drive on a unix box. The code used to do the uploading is C# 3.5. The system currently supports a workflow where after a threshold is met a new subfolder can be generated. The question we have is how many files and/or subfolders can you have in a single folder before there is a degredation in performance - in serving the images up through IIS 7 and reading/writing through code?

  • Why do values in the row I insert not match the values in the insert query?

    - by user202411
    I just can't understand why is my database (mysql) behaving like this! My console shows that the record is created properly (please, notice the "remote_id" value): Tweet Create (0.3ms) INSERT INTO `tweets` (`remote_id`, `text`, `user_id`, `twitter_account_id`) VALUES (12325438258, 'jamaica', 1, 1) But when I check the record, it shows that the remote_id is 2147483647 intead of the provided value (12325438258 in the example above)... This table has many entries, but this field is always written with 2147483647... It was supposed to fill this space with an unique id (which I guarantee you is being generated properly).

  • Wrapping pre-made elements using GWT?

    - by user246114
    Hi, I've been working with GWT for awhile, I can't find a way to integrate it with a preexisting website which is a real downer. My page content is already generated for me using jsp, like: <div id='A'></div> <div id='B'></div> etc. there is no way for me to do something like this though: public void onModuleLoad() { SimplePanel spA = new SimplePanel( Document.getElementById("A")); spA.add(new Label("hello")); SimplePanel spB = new SimplePanel( Document.getElementById("B")); spB.setWidth("200px"); etc .. } seems like there's no way to just wrap a pre-existing element. Is this true, or am I missing how to do this? I need be able to wrap a bunch of elements like this, to manipulate them later on. I see TextBox, Button, a few other classes have wrap() methods, however nothing like that exists for elements, Thanks

  • WPF: Creating instances of resources?

    - by oakskc
    I'm brand spanking new to WPF and am trying to play around with projects to better understand what I'm reading. My understanding of a resource is that it is the instance, you can't use it like a factory and create instances of it. For example, a XAML-defined rectangle. You can reference it, but you can't have numerous instances of it all over the surface. In WPF, what would be the way to do that? If I define a Rectangle as a resource with specific properties and wanted to have multiple instances of that within a dynamically-generated grid, how should I be going about it? Or is there a different way I should be trying to do this? Purely academic exercise with no real-world application.

  • Map a struts2 action result to a controller instead of a jsp

    - by Jim
    Hello, I'm working on on a site built using struts2. The vast majority of our targets generate xml, so mapping the result to a jsp page makes sense. A couple of our targets actually generated binaries. I'm wondering if there is a convenient way to say that the result should come from a servlet/controller instead of a jsp. Obviously this could be done by modifying the web.xml so the struts filter doesn't apply to those targets and mapping those targets as servlets, but this is non-ideal. Currently, the struts filter applies to the entire site, and we would like to keep it that way. Ideas? Thanks!

  • Adding a subview larger than cellHeight to a UITableViewCell?

    - by MathieuK
    I'm trying to add a subview to a UITableViewCell and the design that I'm working from demands that this particular subview (an image) needs to be larger than the actual UITableViewCell and thus partly overlap its siblings. So I've set up my table cell, generated my image and added it to the cell's contentView: // rowHeight for the UITableView is 45.0f UIImage *image = [self createCellThumbnail: someImage]; UIImageView *thumbView = [[UIImageView alloc] initWithFrame: CGRectMake(150, -5, 55,55)]; thumbView.transform = CGAffineTransformMakeRotation(0.1f); thumbView.image = image; cell.clipsToBounds = NO; cell.contentView.clipsToBounds = NO; [cell.contentView addSubview: thumbView]; While the image will 'overflow' into the cell below it, the top of the image is always clipped, as demonstrated here: http://imgur.com/WDsAx . Does anyone know if what I'm trying to do is possible with the current approach or should I just figure out a way to draw these images onto the UITableView after all the cells are drawn (it's a non-scrollable tableview, so that would work and be fairly easy).

  • strsplit in R with metacharacter

    - by user1429852
    I have received a large amount of data where the delimiter is a backslash (obviously a bad choice). I'm processing it in R for computation, and having a hard time finding how to split the string since the backslash is a metacharacter. For example, a string would look like this: "1128\0019\XA5\E2R\366\00=15" and I want to split it along the "\" character, but when I run the strsplit command: strsplit(tempStr, "\") Error in strsplit(tempStr, "\") : invalid regular expression '\', reason 'Trailing backslash' When I try to used the "fixed" option, it does not run because it is expecting something after the backslash: strsplit(tempStr, "\", fixed = TRUE) Unfortunately, I can't preprocess the data with another program because the data is generated daily. Please help and thanks!

  • Pop up window dialogs

    - by Omega
    In Cocoa, my application's main window has a button. How can I make it so when you click it, a new window will be generated and set focus to such window so that the main window can not be clicked or interacted with at all? This new window will have a textfield and a submit button. You click it and the window is supposed to close and send the textfield's data back to the main window (and it will recover focus as well). I found this: How to open a new window on button click in Cocoa Mac Application? But the answer doesn't seem to be working for me. The function showWindow doesn't seem to be recognized...

  • Why does this program require MSVCR80.dll?

    - by Runner
    #include <gtk/gtk.h> int main( int argc, char *argv[] ) { GtkWidget *window; gtk_init (&argc, &argv); window = gtk_window_new (GTK_WINDOW_TOPLEVEL); gtk_widget_show (window); gtk_main (); return 0; } I tried putting various versions of MSVCR80.dll under the same directory as the generated executable(via cmake),but none matched. Is there a general solution for this kinda problem? UPDATE Some answers recommend install the VS redist,but I'm not sure whether or not it will affect my installed Visual Studio 9, can someone confirm?

  • What's the easiest way to implement background downloading in Wicket?

    - by David Moles
    I've got a simple Wicket form that lets users select some data and then download a ZIP file (generated on the fly) containing what they asked for. Currently the form button's onSubmit() method looks something like this: public void onSubmit() { IResourceStream stream = /* assemble the data they asked for ... */ ; ResourceStreamRequestTarget target = new ResourceStreamRequestTarget(stream); target.setFileName("download.zip"); RequestCycle.get().setRequestTarget(target); } This works, but of course the request stops there and it's impossible to display any other feedback to the user. What I'd like to have is something like the typical "Your requested download [NAME] should begin automatically. If not, click this link." Ideally, still displaying the same page, so the user can immediately select some different data and download that as well. I imagine it's possible to do this using Wicket's Ajax classes, but I've managed to avoid having to use them so far, and it's not immediately obvious to me how. What's my quickest way out, here?

  • Apache Axis web service clients vs plain SOAP requests.

    - by Andy Pryor
    I'm looking for the best way to consume a Java web service that returns rather large and complex objects. I am currently using Apache Axis clients generated from the wsdl, (using eclipse "generate web service client" tool). We have concerns about performance of this. The service proxy objects are not thread safe, and they are rather heavy to instantiate, 2-3 MB on the JVM. The other alternative is making HTTP connections and building a String SOAP requests. I would have to interpret the response, and build objects from the XML. Would this be a better alternative to the heavy axis objects? I searched for good reading on this, if any one had any links I would greatly appreciate it.

  • Deterministic random number generator with context?

    - by user653133
    I am looking for a seeded random number generator that creates a pool of numbers as a context. It doesn't have to be too good. It is used for a game, but it is important, that each instance of the Game Engine has it's own pool of numbers, so that different game instances or even other parts of the game that use random numbers don't break the deterministic character of the generated numbers. Currently I am using rand() which obviously doesn't have this feature. Are there any c or objective-c generators that are capable of doing what I want? Best regards, Michael

  • having problems in running my java program..

    - by Tarun
    I'm a beginner in java so this question might seem a little stupid, my jdk and jre are installed in C:\program files, I write my program and save it in in my folder G:\start, now my program compiles without any error(the .class file is also generated), but when i run my program it says "unable to locate G:\lib\amd64\jvm.cfg", so i copy the 'lib' folder from my jdk folder and paste it in G:, again program compiles without any error, but when i run it,it gives my a new error saying "unable to locate G:\bin\server\jvm.dll",so i copy the 'bin' folder to g:, but now when i run, it gives me the same error again "unable to locate G:\bin\server\jvm.dll",where am I going wrong?

  • sequentially-consistent atomic load on x86

    - by axe
    Hello all, I'm interested in sequentially-consistent load operation on x86. As far as I see from assembler listing, generated by compiler it is implemented as a plain load on x86, however plain loads as far as I know guaranteed to have acquire semantics, while plain stores are guaranteed to have release. Sequentially-consistent store is implemented as locked xchg, while load as plain load. That sounds strange to me, could you please explain this in details? added Just found in internet, that sequentially-consistent atomic load could be done as simple mov as long as store is done with locked xchg, but there was no prove and no links to documentation. Do you know where can I read about that? Thanks in advance.

  • Hudson: where to download file and stop specific builds running ?

    - by Kim Jong Woo
    I have a file that is generated inside (hudson server) /var/lib/hudson/jobs/jobtitle/1/out.txt I need to fetch this file, but doing a GET request for http://myhudson:8090/job/jobtitle/1/out.txt doesn't actually locate the file. Basically, I have another box that will grab this file from the hudson server. This box will make the out.txt file available for download. Another challenge is the build number directories. How would I be able to use the hudson API to stop or delete the specific builds running ? I am forced to do iterate through all build numbers to send STOP or DELETE api call in php using wget to do the REST API call. This is not very efficient. for ($i=0; $i < 3000; $i++){ exec('wget -O /dev/null "http://myhudson:8090/job/' . 'jobtitle' . '/$i/stop"'); }

  • How to find (or generate) thousands of company names for test/demo purposes

    - by schefdev
    Ok, so this is rightfully a testing question more than a development question, but the two should go hand in hand :) So, I've got a system I'm building which includes business contact information. Pretty common no doubt. My test/demo database currently has randomly generated individual's names loaded (thanks to a handy IRS spreadsheet I found). This has worked great for internal testing and review purposes, but it looks really odd when shown to prospective customers. So.... Does anyone know where I can grab or find a listing of thousands of business names (address information too would be nice)? I've tried various online public information sources (e.g. EDGAR, and county based property records searches), but these all require me to manually stitch together the results in blocks of 50 names or so at a time. I could do this, but was really hoping for a search service or data store out there that had this type of information readily searchable and retrievable in very large batches. Thanks!

  • Pseudorandom Number Generation with Specific Non-Uniform Distributions

    - by carnun
    Hello all, I'm writing a program that simulates various random walks (with differing distributions). At each timestep, I need randomly generated, two dimensional step distances and angles from the distribution of the random walk. I'm hoping someone can check my understanding of how to generate these random numbers. As I understand it I can use Inverse Transform Sampling as follows: If f(x) is the pdf of our random walk that has a non-uniform distribution, and y is a random number from a uniform distribution. Then if we let f(x) = y and solve to find x then we have a random number from the non-uniform distribution. Is this a feasible solution?

  • How to add response headers based on Content-type; getting Content-type before the response is commi

    - by Bozho
    I want to set the Expires header for all image/* and text/css. I'm doing this in a Filter. However: before calling chain.doFilter(..) the Content-type is not yet "realized" after calling chain.doFilter(..) the Content-type is set, but so is content-length, which forbids adding new headers (at least in Tomcat implementation) I can use the extensions of the requested resource, but since some of the css files are generated by richfaces by taking them from inside jar-files, the name of the file isn't x.css, but is /xx/yy/zz.xcss/DATB/.... So, is there a way to get the Content-type before the response is committed.

  • Model's method not being recognized when called

    - by Brian Roisentul
    I'm using ruby on rails 2.3.2 and also using the acts_as_taggable_on puglin. That generated me two db tables: tags and taggings. As I didn't need anything more from those, I didn't create a Tag model, for example. Now the project is more mature, I need to create some methods for tags, so I created a Tag model with some methods in it. The model looks something like this: class Tag < ActiveRecord::Base def self.get_parent parent = Tag.find(self.parent_id) return parent end end When I call it from a controller, it won't find the method. This is the code: tag = Tag.find(tag_id) the_parent = tag.get_parent This will throw an error saying: undefined method `get_parent' for #<Tag id: 13, name: "Historia", parent_id: 12> I don't know what's wrong. Any help will be appreciated.

  • What is the recommended way to split messages in send pipelines?

    - by ToxicAvenger
    I need to split a bizTalk message in the send pipeline. This is easy with disassemblers in receive pipelines, but doesn't work in send pipelines (makes sense). So what is the recommended way to do it? The only easy way to do it is to write the outbound message to file, then reprocess it using a receive pipeline with a disassembler, and then send the generated messages through a outbound pipeline. Honestly, I don't need the additional roundtrip through the message box, but I don't want to create a custom send adapter. Any other suggestions? Any easy way to save messages with multiple parts using the ootb file adapter?

  • What should be contained in a global Subversion ignore pattern for Visual Studio 2010?

    - by Chris Simmons
    After installing and using Visual Studio 2010, I'm seeing some newer file types (at least with C++ projects ... don't know about the other types) as compared to 2008. e.g. .sdf, .opensdf, which I guess are the replacement for ncb files with Intellisense info stored in SQL Server Compact files? I also notice .log files are generated, which appear to be build logs. Given this, what's safe to add to my global ignore pattern? Off the bat, I'd assume .sdf, .opensdf, but what else?
