  • Continuous Progress Bar in Javascript

    - by Goro
    Hello, I am trying to find the best option to create a simple progress bar that I need to be triggered periodically from within another JavaScript script. Every few minutes, a timer would cause the progress bar to start going from 0 to 100%. Once it reaches 100%, the bar would reset to 0. I am trying to implement a smooth animated version of the bar, like this one: http://www.webappers.com/progressBar/. (I tried adapting this particular one but I could not get it to work the way I described) I am looking into the jQuery UI ProgressBar: Is it possible to use it in the manner I have described? Thank you.

  • CAN Controller DLL with Java Application. Unable to open CAN port.

    - by Joseph Lim
    I am creating a Java application that controls a Controller Area Network (CAN) controller via a vendor-supplied can.dll file. can.dll contains a function bool openPort(DWORD memAddr) that allows the application to establish connection with the CAN controller. I wrote a C++ test application, loaded can.dll via LoadLibrary and found this function to be working as it should, i.e. it returns true. However, in my Java application, calling this via JNI or JNA returns false. I hope someone can help me with this problem as I have been trying to fix this problem for more than a week. Thanks :) JL

  • How to increse performance of raster scrolling on Mac ?

    - by Max
    I have a game with a big raster map Now we are using jpeg (4900x4200) And durring the game we need to scroll through this map. We use the following: Class Map extends mx.containers.Canvas and mx.controls.Image on it In constructor we have: public function Map() { super(); image.source = ResourceManager.interactiveManager.map;//big image addChild(image); ...... } for scrolling we are use: if(parentAsCanvas==null){ parentAsCanvas = (parent as Canvas); } parentAsCanvas.verticalScrollPosition = newX; parentAsCanvas.horizontalScrollPosition = newY; In windows, we have very good performance. In Linux and Mac in flashplayer we have a good performance too. But in browsers performance is quite slow! What can we do to resolve it?

  • Javascript image change causes embeded UserControls to flicker

    - by Sam Barham
    I have a n html page being displayed in IE. It has some buttons made up of images with mouseover/mouseout events on them in JavaScript, and a bunch of embedded .Net UserControls. When the mouseover/mouseout events fire, I change the images src to something else (simple rollover effect). The problem is that the UserControls often (but not always) flicker when this happens. To be clear, the images don't flicker, and the rest of the page doesn't flicker, just the embedded controls. This page is local, not coming from a server or anything. So, any ideas? More information : I've noticed that highlighting text does it too...

  • Where should I put WPF specific code when using MVVM?

    - by Surfbutler
    I'm just getting up to speed on MVVM, but all the examples I've seen so far are binding View controls to simple non-WPF specific data types such as strings and ints. However in our app I want to be able to set a button's border brush based on a number in the Model. At the moment, I translate the number into a brush in the ViewModel to keep the View XAML only, but is that right? I don't like putting WPF specific code in the ViewModel, but equally I don't like the idea of putting code-behind on my View panel. Which is the best way? Thanks

  • Controlling PowerPoint Slideshow

    - by Jayesh
    Hi, I have a scenario: There is a Slideshow running in PowerPoint. I want to control the movement [Next and Previous] of the slides. Of course it is possible with the [ and < button on the keyboard], but is there any way in which I can have a custom application listening to the Next and Previous controls? As in, my custom application has nothing but 2 buttons, next and previous, when I click either, the button's event handler should pass the control to the Power Point Application running the slideshow. And thus, the powerpoint will move the slideshow back or forward? Somewhat similar to the way remote, wireless Power Point Presenters work on the s/w end. Thank You.

  • How to have a dynamic theme color in WPF

    - by Ingó Vals
    In WPF I have a few resource dictionaries and in them styles for my panels and controls in my app. I'm reusing the same colors again and again. I actually have 5 colors and they give my app a good color-scheme. However if I wan't to change the theme I have to go into the RD's and change each and every color there. I would like to somewhere have the colors set but don't know how or where. I tried to put a color tag in one RD but as soon as I referenced it in the same RD Visual Studio crashed. Also the best solution would be that I could have the color as a dynamic setting in the app itself so users could even change it themselves.

  • Git index resets itself

    - by trobrock
    Every so often when I run git add . to add new files to my repo my git index will reset and think all the files in the repo have been deleted. I run these commands: git status git add . git status git commit -a -m "Commit message" everything looks fine at all those points until I commit and it says every file was deleted, all I have to do it run git add . and commit again to get the files back, but this becomes a pain. And this doesnt happen every time, maybe about 40% of the time. Anyone know why this might happen? I am on Mac OS 10.6.3 with Git 1.6.6

  • How should the View pull on the Presenter in the MVP pattern

    - by John Leidegren
    I have a ASP.NET Web Forms application and I'm using some dynamic controls in the view which depend on stuff that the presenter exposes. Is it okay for the view in this case to pull on the presenter for that data? Is there anything I should be extra careful about when considering testability and a loosely coupled design. The page in this case has it's own page-life cycle and the presenter doesn't know about this. However, the page-life cycle dictates that somethings must occur at specific moments in the page-life cycle. This smells like trouble... Any known pit falls?

  • Memcache failover and consistent hashing

    - by Industrial
    Hi everyone, I am trying to work out a good way to handle offline/down memcached servers in my current web application that are built with PHP. I just found this link that shows an approach on how to do what I want, I think: http://cmunezero.com/2008/08/11/consistent-memcache-hashing-and-failover-with-php/ Anyhow, it gets me confused when I start working with it and reading the PHP documention about failover with memcache. Why is offline memcache servers added to the $realInstance server pool together with the online servers? Reading the memcache documentation confuses me even more: http://www.php.net/manual/en/memcache.addserver.php status Controls if the server should be flagged as online. Setting this parameter to FALSE and retry_interval to -1 allows a failed server to be kept in the pool so as not to affect the key distribution algorithm. Requests for this server will then failover or fail immediately depending on the memcache.allow_failover setting. Default to TRUE, meaning the server should be considered online. Thanks,

  • Can one TabBarItem be used for two different ViewControllers?

    - by Kash
    I am creating an app with three tabBarItems, but I want to control four ViewControlers with three tabBars. I am trying to use one tabBar for two different viewcontrollers. I am able to change the tabBartitle and icon upon tap, but I cannot reset it so it can go back to it's previous status with previous title and icon. Also, I am confused about using the tabBarController or just tabBar and to call what function to reload/refresh the tabBar status and where exactly? I am fairly new to the iPhone SD, please describe your answer clearly any help will be highly appreciated.

  • Variable height UIViews and labels

    - by Bob Spryn
    Ok so I'm not in a table cell at this point. (I've seen a lot of threads regarding the height of cells.) I have a detail view with a title and description at the top of the view, followed by a tableView below it. If the description is going to vary in length, how do I get the tableView to adjust with it accordingly so it always starts directly below it? I see apple doing this in the app store application. If you look at an application description (as if you were going to buy it), they have an application description, and wherever that ends a scrolling pane of screenshots follow. How do they do the varying height on the text description like that? Are they doing this all programmatically or can I use the layout controls in IB to do the same thing?

  • Silverlight Scrollable Content Problem

    - by Steve
    I am fairy new to Silverlight and I have a problem. I have a grid on a page that is resizable when the user resizes their browser window. In one of the grids columns I want to display dynamically added content that is scrollable, as there is more data than space available. I currently have a scrollViewer with a stack panel inside it, that i programmatically add a user control to and then several user controls to that control depending on the amount of content. My problem is this. The scrollViewer does not respect the available space and as such displays its content outside of the viewable area when there is more data than space. i.e. it does not uses it is not scrollable nature. Hopefully this is something simple that I have missed, but i am banging my head against the wall at the moment. Any help gratefully received.

  • Show different sub-sets of a view model's properties in an edit view

    - by Martin R-L
    In the context of C# 4, ASP.NET MVC 2, and NHibernate; I've got the following scenario: Let's assume an entity Product that have an association to ProductType. In a product edit view; how do I implement that only a sub-set of the product's properties are shown based on the ProductType association in an elegant and DRY way? I.e., different properties shall be shown for different values of a property of the ProductType. Use a product view model builder, and from different view models automagically generate the view with my own Html.EditorForModel() (including drop-downs and other stuff not out-of-the-box)? Attribute the properties of one view model and use the Html.EditorForModel() way aforementioned? Use one model, but implement different web controls (view strategies) (can it be done DRY?)? Something else entirely?

  • Jawa Swing: Dialog with expanding / progressive disclosure?

    - by Electrons_Ahoy
    I've got a dialog in a desktop Java Swing app. What I want is a classic Windows-style Progressive Disclosure dialog, where pressing a "More Options" button opens up a whole extra batch of options on the dialog. (Which can then be hidden again by clicking that same button, which now says something like "Hide".) What's the right way to do this in Swing? I can't seem to google-up anything directly relating to this, and what I have found boils down to "reset the preferred dimensions to 0 and revalidate" which can't possibly be the right way to do this and also causes all kinds of wacky things to happen.

  • How would I go about building a calendar UI control for the iPhone/iPad?

    - by BeachRunnerJoe
    Hello. There are a few different 3rd party code frameworks that include calendar controls, but most of them have a lot of functionality I don't need, plus most of them lack sufficient documentation on how to use them and I'm not a proficient enough iPhone developer figure it out using just the code. So I'm going to attempt to build my own and I was hoping you could provide me with some high-level direction to get started. At a high level, how could I build a simple, calendar control that doesn't do much more than display a calendar (month view, with the current date highlighted) and allows the user to selected a date? Something that looks like the calendar in the upper right corner of this image... Thanks so much in advance for your help!

  • Why ????? is displayed instead of non-english characters?

    - by smhnaji
    I first created a simple HTML page that uses UTF-8 as its character encoding. Then I moved the HTML content as a view in codeigniter and it was still ok (I had used non-english characters that were ok as always) I added a simple dynamic functionality (there is a contact us form in it that emails users feedback to site admin). Please note that the characters were ok at localhost (which is a LAMP server running on Ubuntu 12.04 LTS) Strange is that when I uploaded the app to server, all persian characters are shown as ???? (For example ??? (which means Name) is shown ??? and so so...) I have not even connected to mysql or any other DBMS. It's the only page in the website (it's more an under construction page) and nothing else has been used in it. Maybe I should state that I have also used session library to thank the user after his feedback was sent to admins, nothing else. I have really no idea about the problem. UPDATE Now I can see that the problem is only with cPanel. On Directadmin I can see that everything is normal. Both Chromium and Firefox DO use UTF-8 as page's character encoding. URL is http://WEBSITE.COM/dmf/dynamic/ (dmf is the abbreviation of the project name!). There is nothing non-english in the URL. The page's code is as follows: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>??? ???????</title> <link rel="stylesheet" type="text/css" href="<?php echo base_url('template/css/style.css'); ?>" /> <!-- 1. jquery library --> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"> </script> <!-- 2. flowplayer --> <script src="http://releases.flowplayer.org/5.1.1/flowplayer.min.js"></script> <!-- 3. skin --> <link rel="stylesheet" type="text/css" href="http://releases.flowplayer.org/5.1.1/skin/minimalist.css" /> </head> <body> <div id="wrapper"> <header> <h1>??? ???????</h1> </header> <section id="box-container"> <?php echo form_open('contact', "id='contact-us'"); echo form_fieldset('???? ?? ??'); if ($this->session->userdata('mailsent')) { echo '<div>??????? ???? ??? ????? ??</div>'; $this->session->sess_destroy(); } echo '<input tabindex="1" id="name-in" value="???" type="text" name="name"/> <input tabindex="2" id="mail-in" value="?????" type="email" name="email"/> <textarea tabindex="3" id="content-in" name="message">???????</textarea> <input tabindex="4" id="submit" type="submit" value="?????" />'; echo '<div class="clear"></div>'; echo form_fieldset_close(); echo form_close(); ?> <div id="sms-comp"> <h2>?????? ??????</h2> <p> <span id="comp-title">?? ??? ????</span> ???? ??????? ???? ??? </p> </div> <div id="last-program"> <h2>?????? ????? ??????</h2> <div class="flowplayer"> <video id="my_video_1" width="212" height="126" poster="<?php echo base_url('template/images/img.jpg'); ?>" controls="controls" src="http://archive.org/download/Pbtestfilemp4videotestmp4/video_test.ogv" type='video/mp4'> </video> </div> </div> <div class="clear"></div> </section> </div> <footer> ????? ? ????? : <a href="http://powered-by.com/" target="_blank">????? ???</a> </footer> </body> </html>

  • jquery tabIndex fix

    - by Victor
    On my pages(ASP.NET 3.5) where all input controls have tab order set whenever next input control is not enabled or hidden it goes to the address bar and then to next available control. To fix this behavior, i.e. make it land to the next available control w/o going to address bar I am trying to use jQuery: $(':text,textarea,select').blur(function() { $(this).next(':text, textarea, select').filter(':enabled:visible').focus(); }); But it still goes to the adress bar in some cases. What do I need to correct here?

  • edit opencart header.tpl

    - by user1693350
    I'm trying to edit the header.tpl of an opencart website that uses vqmod - I need to add some more info (text) to each menu link, so basically edit the header file. I've looked into the vqmod manager and files but I can't seem to get it right. Unfortunately, whenever I try to edit the header file, the site breaks -I've tried editing the cached vqmod files as well, no luck with that. Is there a way to reset the vqmod / disable it, then edit the header.tpl and enable vqmod again? Do I need to install a new theme and start from scratch ? Thanks heaps!

  • ASP.net Literal or Page altering HTML string, causing formatting issues

    - by Jon
    We have a service that generates a report (using word templates and a 3rd party library), and then returns a string in HTML. While this HTML isn't great - its formatted correctly in this string. We want this HTML to show up on a page - format intact. What we currently have done is set an ASP.net Literal's text element to this string. While this works, I have noticed that it has reformatted the HTML string slightly. For the most part, it looks like it generated a bunch of new CSS classes, and a new style element in the HTML. This HTML does not exist in the string thats being returned. I could filter all of this back out, but wonder if there is a better way. I assume that the Page itself is altering something. What is the best way to display this raw HTML back to the user? I can't directly use a Response.Write(string), because this page does have a few other controls on it.
