  • Button Click Event Getting Lost

    - by AlishahNovin
    I have a Menu and Submenu structure in Silverlight, and I want the submenu to disappear when the parent menu item loses focus - standard Menu behavior. I've noticed that the submenu's click events are lost when a submenu item is clicked, because the parent menu item loses focus and the submenu disappears. It's easier to explain with code: ParentMenuBtn.Click += delegate { SubMenu.Visibility = (SubMenu.Visibility == Visibility.Visible) ? SubMenu.Collapsed : SubMenu.Visible; }; ParentMenuBtn.LostFocus += delegate { SubMenu.Visibility = Visibility.Collapsed; }; SubMenuBtn.Click += delegate { throw new Exception("This will never be thrown."); }; In my example, when SubMenuBtn is clicked, the first event that triggers is ParentMenuBtn.LostFocus(), which hides the container of SubMenuBtn. Once the container's visibility collapses, the Click event is never triggered. I'd rather avoid having to hide the sub-menu each time, but I'm a little surprised that the Click event is never triggered as a result... I can't put any checks inside the LostFocus() event to see if my SubMenuBtn has focus, because it does not gain focus until after the LostFocus() event is called. In other words, SubMenuBtn.IsFocused = false when LostFocus() is triggered. Anyone have any thoughts about this?

  • Floating point precision in Visual C++

    - by Luigi Giaccari
    HI, I am trying to use the robust predicates for computational geometry from Jonathan Richard Shewchuk. I am not a programmer, so I am not even sure of what I am saying, I may be doing some basic mistake. The point is the predicates should allow for precise aritmthetic with adaptive floating point precision. On my computer: Asus pro31/S (Core Due Centrino Processor) they do not work. The problem may stay in the fact the my computer may use some improvements in the floating point precision taht conflicts with the one used by Shewchuk. The author says: /* On some machines, the exact arithmetic routines might be defeated by the / / use of internal extended precision floating-point registers. Sometimes / / this problem can be fixed by defining certain values to be volatile, / / thus forcing them to be stored to memory and rounded off. This isn't / / a great solution, though, as it slows the arithmetic down. */ Now what I would like to know is that there is a way, maybe some compiler option, to turn off the internal extended precision floating-point registers. I really appriaciate your help

  • Set focus to another control after TreeView click

    - by Chintan Shah
    I have a TreeView control in a Windows application. I am opening another window from the TreeView click (Single Click) event (in tabbed environment, so all windows will appear as a tab in Visual Studio). I want to set focus to one control of the new window. The problem is that, I am able to set the focus on the double click event of the TreeView. But same doesn't seem to be working with the TreeView single-click event. Any workarounds?

  • jQuery - Need help stopping animation on click command.

    - by iamtheratio
    With a few of your help I was able to get the jquery I wanted to work flawlessly, except for one thing.. the animation doesn't stop when i click on the buttons. Scenario: I have an Image, and 3 buttons underneath labeled "1","2", and "3". The jquery will automate the click function every 4500ms and switch from 1 to 2, then 2 to 3 and continuously loop. However the problem is, if I manually click on a 1,2,3 button the animation does not stop. Any ideas how I could accomplish this? jQuery: var tabs; var len; var index = 1; var robot; function automate() { tabs.eq((index%len)).trigger('click'); index++; } robot = setInterval(automate, 5500); jQuery(document).ready(function(){ jQuery(".imgs").hide(); jQuery(".img_selection a").click(function(){ stringref = this.href.split('#')[1]; $(".img_selection a[id$=_on]").removeAttr('id'); this.id = this.className + "_on"; jQuery('.imgs').hide(); if (jQuery.browser.msie && jQuery.browser.version.substr(0,3) == "6.0") { jQuery('.imgs#' + stringref).show(); } else jQuery('.imgs#' + stringref).fadeIn(); return false; }); $('.img_selection a').removeAttr('id').eq(0).trigger('click'); tabs = jQuery(".img_selection a"); len = tabs.size(); }); I tried adding the below code, with a lot of help from this website, but to no avail.. CODE: jQuery(document).ready(function(){ jQuery(".imgs").hide().click(function(){ clearInterval(robot); }); HTML: <!-- TOP IMAGE ROTATION --> <div id="upper_image"> <div id="img1" class="imgs"> <p><img src="images/top_image.jpg" width="900" height="250" alt="The Ratio - Print Projects!" border="0" /></p> </div> <div id="img2" class="imgs"> <p><img src="images/top_image2.jpg" width="900" height="250" alt="The Ratio - In The Works!" border="0" /></p> </div> <div id="img3" class="imgs"> <p><img src="images/top_image3.jpg" width="900" height="250" alt="The Ratio!" border="0" /></p> </div> </div> <!-- / TOP IMAGE ROTATION --> <!-- TOP IMAGE SELECTION --> <ul class="img_selection"> <li><a id="img1_on" class="img1" href="#img1">1</a></li> <li><a class="img2" href="#img2">2</a></li> <li><a class="img3" href="#img3">3</a></li> </ul> <!-- / TOP IMAGE SELECTION -->

  • Distinguish between a single click and a double click in Java

    - by user552279
    Hi, I search the forum and see this codes: public void mouseClicked(MouseEvent e) { if (e.getClickCount() == 2) { System.out.println(" and it's a double click!"); wasDoubleClick = true; } else { Integer timerinterval = (Integer) Toolkit.getDefaultToolkit().getDesktopProperty( "awt.multiClickInterval"); timer = new Timer(timerinterval.intValue(), new ActionListener() { public void actionPerformed(ActionEvent evt) { if (wasDoubleClick) { wasDoubleClick = false; // reset flag } else { System.out.println(" and it's a simple click!"); } } }); timer.setRepeats(false); timer.start(); } } but the code runs incorrectly(Sometime it prints out " and it's a single click!" 2 times . It should print out " and it's a double click!"). Can anybody show me why? or can you give me some better ways to do this? Thank you!

    Click doesn't work - I don't know why and can't find a solution :( ie. Click(150,215) should move mouse to the client area and click there. [DllImport("user32.dll")] private static extern bool ScreenToClient(IntPtr hWnd, ref Point lpPoint); [DllImport("user32", SetLastError = true)] private static extern int SetCursorPos(int x, int y); static void MouseMove(int x, int y) { Point p = new Point(x * -1, y * -1); ScreenToClient(hWnd, ref p); p = new Point(p.X * -1, p.Y * -1); SetCursorPos(p.X, p.Y); } static void Click(int x, int y) { MouseMove(x, y); SendMessage(hWnd, WM_LBUTTONDOWN, (IntPtr)0x1, new IntPtr(y * 0x10000 + x)); SendMessage(hWnd, WM_LBUTTONUP, (IntPtr)0x1, new IntPtr(y * 0x10000 + x)); } Edit: Of course I can use mouse_event for that, but I would like to see a solution for SendMessage()...

  • Click Once Deployment Process and Issue Resolution

    - by Geordie
    Introduction We are adopting Click Once as a deployment standard for Thick .Net application clients.  The latest version of this tool has matured it to a point where it can be used in an enterprise environment.  This guide will identify how to use Click Once deployment and promote code trough the dev, test and production environments. Why Use Click Once over SCCM If we already use SCCM why add Click Once to the deployment options.  The advantages of Click Once are their ability to update the code in a single location and have the update flow automatically down to the user community.  There have been challenges in the past with getting configuration updates to download but these can now be achieved.  With SCCM you can do the same thing but it then needs to be packages and pushed out to users.  Each time a new user is added to an application, time needs to be spent by an administrator, to push out any required application packages.  With Click Once the user would go to a web link and the application and pre requisites will automatically get installed. New Deployment Steps Overview The deployment in an enterprise environment includes several steps as the solution moves through the development life cycle before being released into production.  To make mitigate risk during the release phase, it is important to ensure the solution is not deployed directly into production from the development tools.  Although this is the easiest path, it can introduce untested code into production and result in unexpected results. 1. Deploy the client application to a development web server using Visual Studio 2008 Click Once deployment tools.  Once potential production versions of the solution are being generated, ensure the production install URL is specified when deploying code from Visual Studio.  (For details see ‘Deploying Click Once Code from Visual Studio’) 2. xCopy the code to the test server.  Run the MageUI tool to update the URLs, signing and version numbers to match the test server. (For details see ‘Moving Click Once Code to a new Server without using Visual Studio’) 3. xCopy the code to the production server.  Run the MageUI tool to update the URLs, signing and version numbers to match the production server. The certificate used to sign the code should be provided by a certificate authority that will be trusted by the client machines.  Finally make sure the setup.exe contains the production install URL.  If not redeploy the solution from Visual Studio to the dev environment specifying the production install URL.  Then xcopy the install.exe file from dev to production.  (For details see ‘Moving Click Once Code to a new Server without using Visual Studio’) Detailed Deployment Steps Deploying Click Once Code From Visual Studio Open Visual Studio and create a new WinForms or WPF project.   In the solution explorer right click on the project and select ‘Publish’ in the context menu.   The ‘Publish Wizard’ will start.  Enter the development deployment path.  This could be a local directory or web site.  When first publishing the solution set this to a development web site and Visual basic will create a site with an install.htm page.  Click Next.  Select weather the application will be available both online and offline. Then click Finish. Once the initial deployment is completed, republish the solution this time mapping to the directory that holds the code that was just published.  This time the Publish Wizard contains and additional option.   The setup.exe file that is created has the install URL hardcoded in it.  It is this screen that allows you to specify the URL to use.  At some point a setup.exe file must be generated for production.  Enter the production URL and deploy the solution to the dev folder.  This file can then be saved for latter use in deployment to production.  During development this URL should be pointing to development site to avoid accidently installing the production application. Visual studio will publish the application to the desired location in the process it will create an anonymous ‘pfx’ certificate to sign the deployment configuration files.  A production certificate should be acquired in preparation for deployment to production.   Directory structure created by Visual Studio     Application files created by Visual Studio   Development web site (install.htm) created by Visual Studio Migrating Click Once Code to a new Server without using Visual Studio To migrate the Click Once application code to a new server, a tool called MageUI is needed to modify the .application and .manifest files.  The MageUI tool is usually located – ‘C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bin’ folder or can be downloaded from the web. When deploying to a new environment copy all files in the project folder to the new server.  In this case the ‘ClickOnceSample’ folder and contents.  The old application versions can be deleted, in this case ‘ClickOnceSample_1_0_0_0’ and ‘ClickOnceSample_1_0_0_1’.  Open IIS Manager and create a virtual directory that points to the project folder.  Also make the publish.htm the default web page.   Run the ManeUI tool and then open the .application file in the root project folder (in this case in the ‘ClickOnceSample’ folder). Click on the Deployment Options in the left hand list and update the URL to the new server URL and save the changes.   When MageUI tries to save the file it will prompt for the file to be signed.   This step cannot be bypassed if you want the Click Once deployment to work from a web site.  The easiest solution to this for test is to use the auto generated certificate that Visual Studio created for the project.  This certificate can be found with the project source code.   To save time go to File>Preferences and configure the ‘Use default signing certificate’ fields.   Future deployments will only require application files to be transferred to the new server.  The only difference is then updating the .application file the ‘Version’ must be updated to match the new version and the ‘Application Reference’ has to be update to point to the new .manifest file.     Updating the Configuration File of a Click Once Deployment Package without using Visual Studio When an update to the configuration file is required, modifying the ClickOnceSample.exe.config.deploy file will not result in current users getting the new configurations.  We do not want to go back to Visual Studio and generate a new version as this might introduce unexpected code changes.  A new version of the application can be created by copying the folder (in this case ClickOnceSample_1_0_0_2) and pasting it into the application Files directory.  Rename the directory ‘ClickOnceSample_1_0_0_3’.  In the new folder open the configuration file in notepad and make the configuration changes. Run MageUI and open the manifest file in the newly copied directory (ClickOnceSample_1_0_0_3).   Edit the manifest version to reflect the newly copied files (in this case 1.0.0.3).  Then save the file.  Open the .application file in the root folder.  Again update the version to 1.0.0.3.  Since the file has not changed the Deployment Options/Start Location URL should still be correct.  The application Reference needs to be updated to point to the new versions .manifest file.  Save the file. Next time a user runs the application the new version of the configuration file will be down loaded.  It is worth noting that there are 2 different types of configuration parameter; application and user.  With Click Once deployment the difference is significant.  When an application is downloaded the configuration file is also brought down to the client machine.  The developer may have written code to update the user parameters in the application.  As a result each time a new version of the application is down loaded the user parameters are at risk of being overwritten.  With Click Once deployment the system knows if the user parameters are still the default values.  If they are they will be overwritten with the new default values in the configuration file.  If they have been updated by the user, they will not be overwritten. Settings configuration view in Visual Studio Production Deployment When deploying the code to production it is prudent to disable the development and test deployment sites.  This will allow errors such as incorrect URL to be quickly identified in the initial testing after deployment.  If the sites are active there is no way to know if the application was downloaded from the production deployment and not redirected to test or dev.   Troubleshooting Clicking the install button on the install.htm page fails. Error: URLDownloadToCacheFile failed with HRESULT '-2146697210' Error: An error occurred trying to download <file>   This is due to the setup.exe file pointing to the wrong location. ‘The setup.exe file that is created has the install URL hardcoded in it.  It is this screen that allows you to specify the URL to use.  At some point a setup.exe file must be generated for production.  Enter the production URL and deploy the solution to the dev folder.  This file can then be saved for latter use in deployment to production.  During development this URL should be pointing to development site to avoid accidently installing the production application.’

  • Can I set command line executed games to open in a window instead of fullscreen?

    - by ajwhitaker822
    I really enjoy some of the free Linux games and just downloaded Cave Story, one of my all-time favorites. However, I can only play the game in full screen, 800X600 Resolution. I was wondering if I could run this program in a window instead of full screen. Is there a command or Unity plugin to do this? Also, would the same work to run SuperTux in a window as well? I'm running 12.04 if that makes any difference. Thanks for your help.

  • Why does my .desktop file execute via double click but not from the menu?

    - by Insperatus
    I've installed FTL: Faster Than Light on my girlfriend's Lubuntu machine and created a .desktop file for it. Strangely, the program won't launch via its menu entry under 'Games'. If I navigate to /home/andi/.local/share/applications/ via pcmanfm and double click on FTL Faster Than Light.desktop the game launches without a problem. I know the menu entry is generated through the .desktop file so why won't it launch from the menu? Here's the .desktop file I created: FTL Faster Than Light.desktop

  • jQuery hiding a div on click outside

    - by Lee
    Hi All I would like to build a simple menu for each list element clicked on but hide this div once you click outside it. Here is some simple code which hopefully will make sense. $('.drillFolder').click(function(){ var id = $(this).attr('data-folder'); $(".drillDownFolder ul li > a").attr('data-id', id); $(".drillDownFolder").show(); }); $("body").click(function(e){ if(e.target.className !== "drillDownFolder") { $(".drillDownFolder").hide(); } }); //The hidden div <div class="drillDownFolder" style="display:none"> <ul> <li><a href="#" data-id="">Show Image</a></li> <li><a href="#" data-id="">Edit Image</a></li> </ul> </div> I know whats wrong as the menu is show via the .drillFolder links the body click is then hiding it straight away. How can I avoid this. Thank you if you can advise

  • Friday Fun: Games that Look Like Productivity Apps

    - by Mysticgeek
    We’ve been showing you fun flash games to play during company time on a Friday afternoon. Hopefully while playing them, you haven’t received a “talking to”. Today we show you some cool games to play that look like productivity apps, so the boss will be none the wiser. The website cantyouseeimbusy.com has developed some very neat little games that look like productivity apps like Word and Excel. These apps look exactly like some project you would be working on, but are really neat little games. Here we take a look at three cool ones on the site called Breakdown, Leadership, and Cost Cutter. Leadership Leadership is a cool game that looks like something you would be working in Excel and is a spin off of the classic game Moon Lander. You navigate your ship through a variety of challenging line graphs. Breakdown This one is a knock off of the classic game Break Out. Use your mouse to scroll the racket at the bottom and bounce the ball off of the text in the document. Press the space bar to pause the game and the elements will disappear…good for when the boss comes around. Cost Cutter This one is a puzzle game where it looks like your working on some bar charts in Excel. You need to click combinations of two or more blocks that are the same color. Again, hit the spacebar and the game elements will disappear. If you’re looking for a way to goof off with some simple games without the boss knowing, these will definitely do the trick. Another cool game along these lines is Excit! which we covered previously.

  • Click event keeps firing

    - by Ben Shelock
    I have absolutely no idea why this is happening but the following code seems to be executed a huge ammount of times in all browsers. $('#save_albums').click(function(){ for(var i = 1; i <= 5; i++){ html = $('#your_albums ol li').eq(i).html(); alert(html); } }); Looks fairly innocent to me... Here's the code in it's entirety $(function(){ $('#query').keyup(function(){ var text = encodeURI($(this).val()); if(text.length > 3){ $('#results').load('search.php?album='+text, function(){ $('.album').hover(function(){ $(this).css('outline', '1px solid black') },function(){ $(this).css('outline', 'none') }); $('.album').click(function(){ $('#fores').remove(); $('#yours').show(); if($('#your_albums ol li').length <= 4){ albumInfo = '<li><div class="album">' + $(this).html() + '</div></li>'; if($('#your_albums ol li').length >= 1){ $('#your_albums ol li').last().after(albumInfo); } else{ $('#your_albums ol').html(albumInfo); } } else{ alert('No more than 5 please'); } }); $('#clear_albums').click(function(e){ e.preventDefault; $('#your_albums ol li').remove(); }); $('#save_albums').click(function(){ for(var i = 1; i <= 5; i++){ html = $('#your_albums ol li').eq(i).html(); alert(html); } }); }); } else{ $('#results').text('Query must be more than 3 characters'); } }); });

  • How are events in games handled?

    - by Alex
    In may games that I have played, I have seen events being triggered, such as when you walk into a certain land area while holding a specific object, it will trigger a special creature to spawn. I was wondering, how do games deal with events such as this? Not in a specific game, but in general among games. The first thought I had was that each place has a hard-coded set of events that it will call when something happens there. However, that would be too inefficient to maintain, as when something new is added, that would require modification of every part of the game that would potentially cause the event to be called. Next up, I had the idea of maybe how GUI programming works. In all of the GUI programming I've done, you create a component and a callback function, or a listener. Then, when the user interacts when the button, the callback function is called, allowing you to do something with it. So, I was thinking that in terms of a game, when a land area gets loaded the game loops over a list of all events, creating instances of them and calling public methods to bind them to the current scene. The events themselves then handle what scene it is, and if it is a scene that pertains to the event, will call the public method of the scene to bind the event to an action. Then, when the action takes place, the scene would call all events that are bound to that action. However, I'm sure that's not how games would operate either, as that would require a lot of creating of events all the time. So how to video games handle events, are either of those methods correct, or is it something completely different?

  • No right-click event Firefox 3.6

    - by cdmckay
    I'm in the process of porting an app to JavaScript/CSS and it uses right-click. For some reason Firefox 3.6 for Windows isn't issuing a right-click event, but Chrome and IE do. Here's some test code. If you right-click #test then you get nothing in Firefox but you get an alert under Chrome and IE. <html> <head> <title>Hi</title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript"> $(function(){ $("#test").get(0).oncontextmenu = function() { return false; }; $("#test").mousedown(function() { alert("hi"); }); }); </script> </head> <body> <div id="test" style="background: red;">Hi</div> </body> </html> Why isn't the right-click event being generated in Firefox?
