  • Compatibility issues with <a> and calling a function(); across different web browsers

    - by Matthew
    Hi, I am new to javascript. I wrote the following function rollDice() to produce 5 random numbers and display them. I use an anchor with click event to call the function. Problem is, in Chrome it won't display, works fine in IE, in firefox the 5 values display and then the original page w/anchor appears! I am suspicious that my script tag is too general but I am really lost. Also if there is a display function that doesn't clear the screen first that would be great. diceArray = new Array(5) function rollDice() { var i; for(i=0; i<5; i++) { diceArray[i]=Math.round(Math.random() * 6) % 6 + 1; document.write(diceArray[i]); } } when I click should display 5 rand variables

  • Setting a "dependency property" in code

    - by Matt B
    I'm on a roll today... I have the following code delaring a dependency property inside a class called ActionScreen: #region Dependency Properties & Methods public string DescriptionHeader { get { return (string)GetValue(DescriptionHeaderProperty); } set { SetValue(DescriptionHeaderProperty, value); } } // Using a DependencyProperty as the backing store for DescriptionHeader. This enables animation, styling, binding, etc... public static readonly DependencyProperty DescriptionHeaderProperty = DependencyProperty.Register("DescriptionHeader", typeof(string), typeof(ActionScreen), new UIPropertyMetadata("xxx")); #endregion I bind to this property in my Xaml as so: <GridViewColumn DisplayMemberBinding="{Binding Description}" Header="{Binding DescriptionHeader}" Width="350" /> Now I want to be able to set the parameter from my code behind when I recieve an event - but it's not working: public string DescColText { set { this.Dispatcher.Invoke(DispatcherPriority.Normal, new Action(delegate() { DescriptionHeader = value; })); } }

  • Debugger does not break when debugging PowerShell console

    - by Adam Driscoll
    I'm developing a binary PowerShell module. I have a post build event that copies that module into the 'modules' directory in my "Documents\WindowsPowerShell" folder. I then have the project set to launch PowerShell.exe. My module is loaded via Import-Module and off I go. The problem is my break points are never hit and the debugger does not break on exceptions. If I run PowerShell outside of Visual Studio and then attach the debugger to the process I can break just fine. The other strange this is that my break points are not empty. Typically if different source versions are loaded they will be. I'm running Visual Studio 2010 on a Win 7 box. My module is currently targeting .NET 3.5. I've tried running both the x64 and x86 versions of PS with no luck.

  • Visual C# | Capturing data from a window in a closed-source third-party Win32 application

    - by Zach Albia
    I'm planning on creating a C# Windows Forms app as an extension for a third-party Win32 application but I'm stumped as to how to do this right now. The farthest I've gotten is knowing it involves Win32 Hooking and that there's this open source project called EasyHook that's supposed to allow me to do this. I'd like to know how I can get the text from a textbox or some other data from a control in a third-party Win32 application. The text/data in a control is to be captured from the external application's running window the moment the user presses a button. I guess the question can be summed up as follows: How do you determine the event to hook to when the user clicks a certain button? How do you get the value displayed by a Win32 control at the time the button is clicked?

  • calling facebox in a google maps balloon

    - by XGreen
    Hi Guys, I have a gmap balloon. var marker = createMarker(point, '<div style="width:240px" id="mapsball"><h2>Splash of London</h2><img src="_assets/images/themes/shop.jpg" id="mapThumb" width="100" align="right" /><p>110-112 Hoxton Street</p><p>London</p><p>N1 6SH</p><\/div>'); map.addOverlay(marker, icon); and a facebox attached to the click event of the image ('#mapsball') which opens it in a facebox $(function() { $("body").delegate("#mapThumb", "click", function(){ jQuery.facebox('<img src="_assets/images/themes/shop.jpg" align="right"/>'); }); }); this works fine in ff and safari and chrome. but doesn't fire in ie. I don't get a js error in ie so I am assuming it just doesn't get binded. any help would be greatly appreciated.

  • Android - Notification bar height from a service

    - by Vitaliy
    Hi, The application I'm working on is a service which runs in the background in android. The problem is that I need to determine the height of the notification bar for some functionality of the service. I found a number of solutions for this, for regular activities - a view inside an activity can determine its own height without the notification bar, based on checking its actual view size from its onSizeChanged event, after it is already drawn. However, this is not applicable to a service which has no physical view drawn. I would really appreciate any ideas on getting the size of the notification bar at a system level, perhaps? Thanks so much! Vitaliy

  • Is MonoTouch worth the cost or should I just learn Objective-C?

    - by jamesaharvey
    After sitting through a session today on Mono at a local .Net event, the use of MonoTouch was 'touched' upon as an alternative for iPhone development. Being very comfortable in C# and .Net, it seems like an appealing option, despite some of the quirkiness of the Mono stack. However, since MonoTouch costs $400, I'm somewhat torn on if this is the way to go for iPhone development. Anyone have an experience developing with MonoTouch and Objective-C, and if so is developing with MonoTouch that much simpler and quicker than learning Objective-C, and in turn worth the $400?

  • Need help on Coda slider tabs to move inside an overflow:hidden div

    - by Reden
    I'm not too good at javascript. and hope I can get a bit of help. I'm using Coda Slider 2.0, and have designed it to where the tabs are another slider to the right of the main slider, and each item. Basically like this mootools plugin http://landofcoder.com/demo/mootool/lofslidernews/index2.1.html Problem is the items will not scroll. How do I make the items (or tabs to the right) scroll down as the slider rotates? Otherwise the slider will show the 4th slide but not scroll to the 4th item on the right, but Thanks everyone. Here is the Coda-Slider plugin: // when the DOM is ready... $(document).ready(function () { var $panels = $('#slider .scrollContainer > div'); var $container = $('#slider .scrollContainer'); // if false, we'll float all the panels left and fix the width // of the container var horizontal = true; // float the panels left if we're going horizontal if (horizontal) { $panels.css({ 'float' : 'left', 'position' : 'relative' // IE fix to ensure overflow is hidden }); // calculate a new width for the container (so it holds all panels) $container.css('width', $panels[0].offsetWidth * $panels.length); } // collect the scroll object, at the same time apply the hidden overflow // to remove the default scrollbars that will appear var $scroll = $('#slider .scroll').css('overflow', 'hidden'); // apply our left + right buttons $scroll .before('<img class="scrollButtons left" src="images/scroll_left.png" />') .after('<img class="scrollButtons right" src="images/scroll_right.png" />'); // handle nav selection function selectNav() { $(this) .parents('ul:first') .find('a') .removeClass('selected') .end() .end() .addClass('selected'); } $('#slider .navigation').find('a').click(selectNav); // go find the navigation link that has this target and select the nav function trigger(data) { var el = $('#slider .navigation').find('a[href$="' + data.id + '"]').get(0); selectNav.call(el); } if (window.location.hash) { trigger({ id : window.location.hash.substr(1) }); } else { $('ul.navigation a:first').click(); } // offset is used to move to *exactly* the right place, since I'm using // padding on my example, I need to subtract the amount of padding to // the offset. Try removing this to get a good idea of the effect var offset = parseInt((horizontal ? $container.css('paddingTop') : $container.css('paddingLeft')) || 0) * -1; var scrollOptions = { target: $scroll, // the element that has the overflow // can be a selector which will be relative to the target items: $panels, navigation: '.navigation a', // selectors are NOT relative to document, i.e. make sure they're unique prev: 'img.left', next: 'img.right', // allow the scroll effect to run both directions axis: 'xy', onAfter: trigger, // our final callback offset: offset, // duration of the sliding effect duration: 500, // easing - can be used with the easing plugin: // http://gsgd.co.uk/sandbox/jquery/easing/ easing: 'swing' }; // apply serialScroll to the slider - we chose this plugin because it // supports// the indexed next and previous scroll along with hooking // in to our navigation. $('#slider').serialScroll(scrollOptions); // now apply localScroll to hook any other arbitrary links to trigger // the effect $.localScroll(scrollOptions); // finally, if the URL has a hash, move the slider in to position, // setting the duration to 1 because I don't want it to scroll in the // very first page load. We don't always need this, but it ensures // the positioning is absolutely spot on when the pages loads. scrollOptions.duration = 1; $.localScroll.hash(scrollOptions); /////////////////////////////////////////////// // autoscroll /////////////////////////////////////////////// // start to automatically cycle the tabs cycleTimer = setInterval(function () { $scroll.trigger('next'); }, 2000); // how many milliseconds, change this to whatever you like // select some trigger elements to stop the auto-cycle var $stopTriggers = $('#slider .navigation').find('a') // tab headers .add('.scroll') // panel itself .add('.stopscroll') // links to the stop class div .add('.navigation') // links to navigation id for tabs .add("a[href^='#']"); // links to a tab // this is the function that will stop the auto-cycle function stopCycle() { // remove the no longer needed stop triggers clearInterval(cycleTimer); // stop the auto-cycle itself $buttons.show(); // show the navigation buttons document.getElementById('stopscroll').style.display='none'; // hide the stop div document.getElementById('startscroll').style.display='block'; // block the start div } // bind stop cycle function to the click event using namespaces $stopTriggers.bind('click.cycle', stopCycle); /////////////////////////////////////////////// // end autoscroll /////////////////////////////////////////////// // edit to start again /////////////////////////////////////////////// // select some trigger elements to stop the auto-cycle var $startTriggers_start = $('#slider .navigation').find('a') // tab headers .add('.startscroll'); // links to the start class div // this is the function that will stop the auto-cycle function startCycle() { // remove the no longer needed stop triggers $buttons.hide(); // show the navigation buttons $scroll.trigger('next'); // directly to the next first cycleTimer = setInterval(function () { // now set timer again $scroll.trigger('next'); }, 5000); // how many milliseconds, change this to whatever you like document.getElementById('stopscroll').style.display='block'; // block the stop div document.getElementById('startscroll').style.display='none'; // hide the start div } // bind stop cycle function to the click event using namespaces $startTriggers_start.bind('click.cycle', startCycle); /////////////////////////////////////////////// // end edit to start /////////////////////////////////////////////// });

  • Create iPhone app programmatically, in its entirety

    - by miorel
    I recently became interested in iPhone app development, so I've been looking at online tutorials, and also reading a book, trying out the examples as I go along. I'm getting better, but one of the things I still find quite annoying about the usual development model is that I really have no idea what the SDK is really doing behind the scenes to make the app "work" because Apple protects me from this. For example, when I make connections on interface builder, this presumably corresponds to code being generated somewhere... Where that code is and what it does and how it works are not obvious (to me). So I'm wondering, is it possible to create an iPhone app entirely programmatically? That is, have execution start in some main method, which will then programmatically create any views, register event listeners, etc. And if yes, what are some good resources for something like this?

  • VB.NET - Read lines from command line to Windows form possible?

    - by Yiu Korochko
    Hey Overflow, I have an application which serves as a user interface for a spartan/command line program. I have the program running on a separate process, and my application monitors it to see if it is responding and how mush CPU it is utilising. Now I have a list of files in my program (listbox) which are to be sent to the application, which happens fine. But I want to be able to read text from the com-line so as to determine when the first file has been processed. Com-line says one of "selecting settings", "unsupported format" and "cannot be fixed". What I want to be able to do is when it says one of these three things, remove item(0) in listbox1. Is this possible? I thought of programming an event which handles com_exe.print or something or other, if possible.

  • Resizing JPopupMenu and avoiding a "flicker" issue

    - by Avrom
    Hi, I am trying to implement a search results popup list similar to the style found here: http://www.inquisitorx.com/ (I'm not trying to implement a Google search, I'm just using this as a rough example of the style I'm working on.) In any event, I am implementing this by using a JList contained within a JPopupMenu which is popped up underneath a JTextField. When a user enters search terms, the list changes to reflect different matching results. I then call pack on the JPopupMenu to resize it. This works, however, it creates a slight flicker effect since it is actually hiding the popup and showing a popup. (See the private method getPopup in JPopupMenu where it explicitly does this.) Is there any way to just get it to just resize itself (aside from using a JWindow)?

  • Information Label

    - by caisenm
    I am trying to make an information label that should display the events the application doing. deleting data, reading data, writing data, connection to db. etc.. I've added a label to my form and I am changing its text property for each operation like: label1.Text = "stored procedure is being executed.."; But, in the run time the text of the label does not change. I've tried to add the method Application.DoEvents(); to every place I've changed the label's text property. It works fine. But it looks silly. So I've tried to add this method to my label's "TextChanged" event. But it does not work! Am I doing something wrong? Or, is there any efficient way to make an information label?

  • ScrolledWindow and wx.EVT_LEAVE_WINDOW

    - by Joril
    Hi everyone! I have a frame with a textctrl. When the mouse enters the textctrl (EVT_ENTER_WINDOW) I show a PopupWindow on top of the textctrl, and when the mouse leaves the popup (EVT_LEAVE_WINDOW) I hide it again. Everything works fine, except when inside the PopupWindow there's a ScrolledWindow with shown scrollbars. The EVT_LEAVE_WINDOW gets fired when I move the mouse on top of a scrollbar, so it looks like wxPython thinks the scrollbars are not part of the scrolledwindow.. :/ I tried binding the event to the popup or the scrollwindow itself, but nothing changes.. Is there a way I could get around this? Many thanks! (wxPython 2.8.8.0 on Xubuntu 8.10)

  • Lot of time spent with following waits 'SQL*Net message from client' and 'wait for unread message on

    - by Shravan
    My application that wraps around Oracle Data pump's executables IMPDP and EXPDP takes random amounts of time for the same work. On further investigation, I see it waiting for again random amounts of time with the event 'wait for unread message on broadcast channel'. This makes the application take anytime b/w 10 minutes to over an hour for the same work. I fail to understand if this has something to do with the way my application uses these executables, or it has got something to do with Load on my server or something totally alien to me.

  • Can a http server detect that a client has cancelled their request?

    - by Nick Retallack
    My web app must process and serve a lot of data to display certain pages. Sometimes, the user closes or refreshes a page while the server is still busy processing it. This means the server will continue to process data for several minutes only to send it to a client who is no longer listening. Is it possible to detect that the connection has been broken, and react to it? In this particular project, we're using Django and NginX, or Apache. I assumed this is possible because the Django development server appears to react to cancelled requests by printing Broken Pipe exceptions. I'd love to have it raise an exception that my application code could catch. Alternatively, I could register an unload event handler on the page in question, have it do a synchronous XHR requesting that the previous request from this user be cancelled, and do some kind of inter-process communication to make it so. Perhaps if the slower data processing were handed to another process that I could more easily identify and kill, without killing the responding process...

  • CreateChildControls AFTER Postback

    - by Francois
    I'm creating my own CompositeControl: a collection of MyLineWebControl and a "add" button. When the user press the "add" button, a new MyLineWebControl is added. In CreateChildControls(), I run through my model (some object MyGridOfLines which has a collection of MyLine) and add one MyLineWebControl for each MyLine. In addButton.Click, I add a new MyLine to my object MyGridOfLines. But, since the Click event method is called after CreateChildControls(), the new MyLineWebControl will be only displayed on the next postback. What can I do to "redraw" immediately my control, without loosing values that I've entered in each input?

  • how to lengthen the pause between the words with text-to-speech (pyTTS or SAPI5)

    - by Berry Tsakala
    Is it possible to extend the gap between spoken words when using text to speech with SAPI5 ? The problem is that esp. with some voices, the words are almost connected to each other, which makes the speech more difficult to understand. I'm using python and pyTTS module (on windows, since it's using SAPI) I tried to hook to the OnWord event and add a time.sleep() or tts.Pause(), but apparently even though all the events are caught, they are being processed only at the end of the spoken text, whether i'm using the sync or async flag. In this NON WORKING example, the sleep() method is executed only after the sentence is spoken: tts = pyTTS.Create() def f(x): tts.Pause() sleep(0.5) tts.Resume() tts.OnWord = f tts.Speak(text)

  • Error when running MSpec - how do I troubleshoot?

    - by Tomas Lycken
    I am following this guide to installing and using MSpec, but at the step where he runs MSpec for the first time, I get the following error: Could not load file or assembly 'file:///[...]\Nehemiah\Nehemiah.Specs\bin\Debug\Nehemiah.Specs.dll' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded. I have - to my knowledge - done everything more or less exactly like he did up to this step, except where differences arise because he's using VS2008 and I'm using VS2010, and everything has worked so far. The project Nehemijah.Specs (and the entire solution) builds without problem, both in Visual Studio and on my build server, and I can't find anything useful in Event Viewer (although I might not be looking in the right place here...) What to do?

  • jQuery UI: Drag and clone from original div, but keep clones

    - by Nic Hubbard
    I have a div, which has jQuery UI Draggable applied. What I want to do, is click and drag that, and create a clone that is kept in the dom and not removed when dropped. Think of a deck of cards, my box element is the deck, and I want to pull cards/divs off that deck and have them laying around my page, but they would be clones of the original div. I just want to make sure that you cannot create another clone of one of the cloned divs. I have used the following, which didn't work like I wanted: $(".box").draggable({ axis: 'y', containment: 'html', start: function(event, ui) { $(this).clone().appendTo('body'); } });
