  • DSL modem problem in 11.10

    - by Misterious
    Earlier I used Windows 7 and the modem used to work absolutely fine. Even when it got disconnected it used to reconnect automatically without any trouble. But then I installed Ubuntu 11.10 on dual-boot and set up the modem connection properly but the modem now disconnects much more frequently (earlier it disconnected once in 5 hours or so and after Ubuntu in 5 minutes!). Also once disconnected, it does not reconnect even when I have checked the "Connect Automatically" button. I have to restart the system to reconnect it. I the clean installed Windows and modem works perfectly fine again. What is the reason for this and how can I solve this? I really want to use Ubuntu but due to this problem I can't.

  • Backbone.js, Rails and code duplication

    - by Matteo Pagliazzi
    I'm building a web app and I need a JS framework like Backbone.js to work with my backend rovided by Rails that mostly return JSON objects after DB queries. Searching on the web I've discovered Backbone which seems to be complete, quite populare and actively developed but I've noticed that a lot of things done by Backbone are simply a duplicte of the works done by Rails: for example validation and models. My idea of "perfect" (for my actual needs) JS mvc (it can't be called mvc but i don't have any other names) is something really simple that has a function for each action in my Rails controller that are triggered by a specific event (user/hash changes, click on a button...) and send requests to the server that respond with a JSON object then I'll load a template or execute some JS code. Do you have any concern/suggestion about my idea? Do you know some "micro" js framework like what i have described? If you have worked with backone.js + rails what can you suggest me?

  • Live Meeting error: malformed email address... or IS IT???

    - by PeterBrunone
    During a remote SharePoint training session this morning, Live Meeting presented one of our instructors with the following gem:  "An attendee email address is malformed".  This was particularly troubling since a wizard took care of adding all the entries, and they looked correct (even after being sifted through my character analysis tool).As it turns out, the addresses were indeed correct.  As sometimes happens, though, at the line breaks, it looked like there was no space between the semicolon and the following email address.  Since I'm a member in good standing of the "I wonder what this button does" school of thought, I added an extra space after each of these cramped little semicolons -- and the invitation executed flawlessly.Coincidence?  Maybe... but you can bet I'm going to keep trying dumb stuff like that when the error message doesn't make sense.  Think of it as the tech support equivalent of "Ask a silly question..."

  • Apple Magic Trackpad multitouch configuration

    - by Sureshkannan Duraisamy
    Today I installed the Ubuntu 10.10 release on my Desktop PC. I was running Ubuntu 10.04 LTS with an Apple Magic Trackpad and everything was working fine. After today's fresh installation of Ubuntu 10.10, I don't see my Apple Magic Trackpad's multitouch working. Two-finger scrolling and three-finger third mouse button clicking are completely broken. Has anyone else experienced a similar issue? Has anyone had success with Ubuntu 10.10 and an Apple Magic TrackPad? Please help me to fix this issue. Your help is highly appreciated...

  • Accessing UI elements from delegate function in Windows Phone 7

    - by EpsilonVector
    I have the following scenario: a page with a bunch of UI elements (grids, textblocks, whatever), and a button that when clicked launches an asynchronous network transaction which, when finished, launches a delegate function. I want to reference the page's UI elements from that delegate. Ideally I would like to do something like currentPage.getUIElementByName("uielement").insert(data), or even uielement.insert(data), or something similar. Is there a way to do this? No matter what I try an exception is being thrown saying that I don't have permissions to access that element. Is there a more correct way to handle updating pages with data retrieved over network?

  • Integrating eBay and PayPal inventory

    - by JW01
    Say I have an item for sale on eBay, and the same item for sale on another site via PayPal. Is it possible to have sales on one site reflected in the inventory for the other site, and vice-versa? In other words, if I have ten items for sale, and I buy one on either site, it should show that there are nine items left on both sites. I know that PayPal has an API for setting the inventory level of an item associated with a button. eBay also has an API for controlling an item's inventory. I'm wondering if anyone has tried to integrate them.

  • Package information was last updated 59 days ago even though Ubuntu is up to date

    - by Luuz
    I'm using ubuntu 11.10 and in the update manager I have a message that says package information last updated 59 days ago press the check button to check for software updates I do that, but i'm up to date. I checked other threads with this same problem, and saw i should do sudo apt-get update in a terminal to see which repository is not up to date and when I did, I got this message: Failed to fetch http://extras.ubuntu.com/ubuntu/dists/oneiric/Release Then I checked for this repository in software sources but couldn't find this specific one. In my /etc/apt/sources.list.d I have only one line: deb http://archive.canonical.com/ubuntu oneiric partner #Added by software-center So now I don't know what to do more. Should I upgrade to 12.04 and will it solve my problem? I wouldn't want to upgrade if there is a problem in the last version but I don't know much about Ubuntu so, can anyone help me please? Thank you!!

  • Compiz command plugin won't register keyboard shortcuts

    - by David Moles
    Per this discussion I've enabled the Compiz commands plugin in order to try to bind some keyboard shortcuts to wmctrl actions. CCSM captures my keystrokes just fine, but no matter what keystroke I try or what command I bind it to (everything from my original intention of binding Super-1, Super-2 etc. to wmctrl -o 0,0, wmctrl -o 2560,0, etc., to binding Ctrl-Alt-Shift-L to gnome-terminal). Basic compiz shortcuts for window switching and so on -- even custom ones -- seem to work fine, but the command plugin doesn't seem to be working at all. I also notice the following symptom: when I open the keyboard shortcut tab in CCSM, the keyboard shortcuts often at first appear blank, though if you click on the blank button, the correct value is still there. Also possibly related, I've noticed that gnome-terminal doesn't seem to notice the Super key, though other apps (e.g. CCSM, Emacs) register it fine. Anyway, it seems like something's eating my keystrokes. Any ideas?

  • How to Use Windows 8's Storage Spaces to Mirror & Combine Drives

    - by Chris Hoffman
    “Storage Spaces” is a new feature in Windows 8 that can combine multiple hard drives into a single virtual drive. It can mirror data across multiple drives for redundancy or combine multiple physical drives into a single pool of storage. You can even create pools of storage larger than the amount of physical storage space you have available. When the physical storage fills up, you can plug in another drive and take advantage of it with no additional configuration required. Storage Spaces is similar to RAID or LVM on Linux.

  • FAQ: Highlight GridView Row on Click and Retain Selected Row on Postback

    - by Vincent Maverick Durano
    A couple of months ago I’ve written a simple demo about “Highlighting GridView Row on MouseOver”. I’ve noticed many members in the forums (http://forums.asp.net) are asking how to highlight row in GridView and retain the selected row across postbacks. So I’ve decided to write this post to demonstrate how to implement it as reference to others who might need it. In this demo I going to use a combination of plain JavaScript and jQuery to do the client-side manipulation. I presumed that you already know how to bind the grid with data because I will not include the codes for populating the GridView here. For binding the gridview you can refer this post: Binding GridView with Data the ADO.Net way or this one: GridView Custom Paging with LINQ. To get started let’s implement the highlighting of GridView row on row click and retain the selected row on postback.  For simplicity I set up the page like this: <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>You have selected Row: (<asp:Label ID="Label1" runat="server" />)</h2> <asp:HiddenField ID="hfCurrentRowIndex" runat="server"></asp:HiddenField> <asp:HiddenField ID="hfParentContainer" runat="server"></asp:HiddenField> <asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Trigger Postback" /> <asp:GridView ID="grdCustomer" runat="server" AutoGenerateColumns="false" onrowdatabound="grdCustomer_RowDataBound"> <Columns> <asp:BoundField DataField="Company" HeaderText="Company" /> <asp:BoundField DataField="Name" HeaderText="Name" /> <asp:BoundField DataField="Title" HeaderText="Title" /> <asp:BoundField DataField="Address" HeaderText="Address" /> </Columns> </asp:GridView> </asp:Content>   Note: Since the action is done at the client-side, when we do a postback like (clicking on a button) the page will be re-created and you will lose the highlighted row. This is normal because the the server doesn't know anything about the client/browser not unless if you do something to notify the server that something has changed. To persist the settings we will use some HiddenFields control to store the data so that when it postback we can reference the value from there. Now here’s the JavaScript functions below: <asp:content id="Content1" runat="server" contentplaceholderid="HeadContent"> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js" type="text/javascript"></script> <script type="text/javascript">       var prevRowIndex;       function ChangeRowColor(row, rowIndex) {           var parent = document.getElementById(row);           var currentRowIndex = parseInt(rowIndex) + 1;                 if (prevRowIndex == currentRowIndex) {               return;           }           else if (prevRowIndex != null) {               parent.rows[prevRowIndex].style.backgroundColor = "#FFFFFF";           }                 parent.rows[currentRowIndex].style.backgroundColor = "#FFFFD6";                 prevRowIndex = currentRowIndex;                 $('#<%= Label1.ClientID %>').text(currentRowIndex);                 $('#<%= hfParentContainer.ClientID %>').val(row);           $('#<%= hfCurrentRowIndex.ClientID %>').val(rowIndex);       }             $(function () {           RetainSelectedRow();       });             function RetainSelectedRow() {           var parent = $('#<%= hfParentContainer.ClientID %>').val();           var currentIndex = $('#<%= hfCurrentRowIndex.ClientID %>').val();           if (parent != null) {               ChangeRowColor(parent, currentIndex);           }       }          </script> </asp:content>   The ChangeRowColor() is the function that sets the background color of the selected row. It is also where we set the previous row and rowIndex values in HiddenFields.  The $(function(){}); is a short-hand for the jQuery document.ready event. This event will be fired once the page is posted back to the server that’s why we call the function RetainSelectedRow(). The RetainSelectedRow() function is where we referenced the current selected values stored from the HiddenFields and pass these values to the ChangeRowColor() function to retain the highlighted row. Finally, here’s the code behind part: protected void grdCustomer_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { e.Row.Attributes.Add("onclick", string.Format("ChangeRowColor('{0}','{1}');", e.Row.ClientID, e.Row.RowIndex)); } } The code above is responsible for attaching the javascript onclick event for each row and call the ChangeRowColor() function and passing the e.Row.ClientID and e.Row.RowIndex to the function. Here’s the sample output below:   That’s it! I hope someone find this post useful! Technorati Tags: jQuery,GridView,JavaScript,TipTricks

  • How are buttons made to be clicked?

    - by Johnny
    I just want to ask a general question. According to that answer, Ill continue thinking. You know in games there are lots of clickable items. Play button, exit, comboboxes maybe etc. My question is are those buttons drawn in same canvas with background and all other things, or for every different thing there is another canvas object? My question is about for general. Im not asking about a specific game, im asking how they are made generally. Im planning to start a game on Android, and Im confused actually how to design buttons, and other object. Probably Im going to use View/SurfaceView for now. I don't have much experience with OpenGL yet. Thanks in advance.

  • Mouse buttons and all keyboard buttons except alt and super randomly stops working

    - by bobbaluba
    A couple of times lately, unity appears to not accept button presses from neither the mouse or the keyboard. This happens after a random amount of time, usually a couple of hours, or right after boot. The weird thing is: I can still move the mouse around. I can press alt to get the unity menu thingy (but i can't type anything in it) I can press super to show/hide the unity search. None of the applications seem to get the input Ive tried connecting a second mouse, same issue I can press ctrl+alt+f1 to drop to a shell tty The shell works fine Now, this is definitely a bug, probably in unity(?), but it's hard to search for when I don't know what's causing it. Is there something I can do to debug? I've found some people that appears to be having the same problem with the mouse only, but most of the time, their questions are unanswered or closed for being too specific. What would be a good strategy to fix this? Should I report it as a bug?

  • Share on Facebook does not show thumbnail images

    - by matt_tm
    I have a PHP application which has a "Share on Facebook" button that, On the development server shows the thumbnail images correctly and allows the user to select between them On the live server, it does NOT show the thumbnail images at all. The relevant portion of the .htaccess file is: # Set up caching on media files for 2 days <FilesMatch "\.(gif|jpg|jpeg|png|flv)$"> ExpiresDefault A172800 Header append Cache-Control "public" </FilesMatch> I'm using the exact same set of php files and .htaccess, but the server configuration is different. What could be causing this? Note that the text appears fine. Edit1 We are also doing some URL rewriting related to images in the .htaccess (on both servers): ... RewriteRule ^.*/content/image/(.*)$ content/image/$1 [L] ... RewriteRule ^.*/images/(.*)$ images/$1 [L] ... Would that be somehow making a difference? Images appear fine all throughout the site.

After downloading the source code be sure to set Commands2.Web as the StartUp Project and Default.aspx as the StartPage. In my last post, Commands in Task-It - Part 1, we looked at a very simple solution that demonstrated how a single command instance (SaveCommand) could be bound to two UI controls, a Button and a RadTreeViewItem. In this example we'll get more complex, binding a single command instance (MoveToCommand) will be bound to multiple RadMenuItems in a RadContextMenu that is tied to a RadGridView. This time we'll also set a separate CommandParameter on each RadMenuItem, so when the command is invoked, we will be able to use that parameter to determine what to do next.

  • Customizing UPK outputs (Part 2 - Player)

    - by [email protected]
    There are a few things that can be done to give the Player output a personalized look to match your corporate branding. In my previous post, I talked about changing the logo. In addition to the logo, you can change the graphic in the heading, button colors, border colors and many other items. Prior to making any customizations, I strongly recommend making a copy of the existing Player style. This will give you a backup in case things go wrong. I'd also recommend that you create your own brand. This way, when you install the newest updates from us, your brand will remain intact. Creating your own brand is pretty easy. Make sure you have modify permissions on the publishing styles directory, if you are using a multi-user installation. Under the Publishing/Styles folder, create a new folder with your company name. Copy all the publishing styles from the UPK folder to your newly created folder. Now, when you go through the Publishing wizard, you will have two categories to choose from: the UPK category or your custom category. Now, for updating the Player output. First, the graphic that appears on the right hand side of the Player. If you're using a multi-user installation, check out the player style from your custom brand. Open the player style. Open the img folder. The file named "banner_image.png" represents the graphic that appears on the right hand side of the player. It is currently sized at 425 x 54. Try to keep your graphic about the same size. Rename your graphic file to be "banner_image.png", and drag it into the img folder. Save the package. Check in the package if you are in a multi-user installation. You've just updated the banner heading! Next, let's work on updating some of the other colors in the player. All the customizable areas are located in the skin.css file which is in the root of the Player style. Many of our customers update the colors to match their own theme. You don't have to be a programmer to make these changes, honest. :) To change the colors in the player: Make a copy of the original skin.css file. (This is to make sure you have a working version to revert to, in case something goes wrong.) Open the skin.css file from the Player package. You can edit it using Notepad. Make the desired changes. Save the file. Save the package. Publish to view your new changes. When you open the skin.css, you will see groupings like this: .headerDivbar { height: 21px; background-color: #CDE2FD; } Change the value of the background-color to the color of your choice. Note that you cannot use "red" as a color, but rather you should enter the hexadecimal color code. If you don't know the color code, search the web for "hexadecimal colors" and you'll find many sites to provide the information. Here are a few of the variables that you can update. Heading: .headerDivbar -this changes the color of the banner that appears under the graphic Button colors: .navCellOn - changes the color of the mode buttons when your mouse is hovering on them. .navCellOff - changes the color of the mode buttons when the mouse is not over them Lines: .thorizontal - this is the color of the horizontal lines surrounding the outline .tvertical - this is the color of the vertical lines on the left and right margin in the outline. .tsep - this is the color of the line that separates the outline from the content area Search frame: .tocSearchColor - this is the color of the search area .tocFrameText - this is the background color of the TOC tree. Hint: If you want to try out the changes prior to updating the style, you can update the skin.css in some content you've already published for the player (it's located in the css folder of the player package). This way, you can immediately see the changes without going through publishing. Once you're happy with the changes, update the skin.css in player style. Want to customize more? Refer to the "Customizing the Player" section of the Content Development manual for more details on all the options in the skin.css that can be changed, and pictures of what each variable controls. I'd love to see how you've customized the player for your corporate needs. Also, if there are other areas of the player you'd like to modify but have not been able to, let us know. Feel free to share your thoughts in the comments. --Maria Cozzolino, Manager of Requirements & UI Design for UPK

  • Combining Multiple Queries and Parameters into One Operation

    - by shay.shmeltzer
    This question came up twice this week and while the solution is explained in a couple of previous blog entries I did, I thought that showing off the complete solution in a single video would be nice. The scenario is that you have two VOs with queries that are based on a parameter, I showed in the past how to create a parameter form that executes the query - and you can do this for both. But what if you actually need just one value to drive both queries? How do you combine two parameter forms and two buttons into one? This is what this video shows you. The steps are: Creating two parameter forms Setting the value of a parameter in the binding tab Creating a backing bean to execute the code for one button Adding the code to execute another operation Remarking the parts that can be dropped from the screen Check it out here:

  • how do you read from system.out in Java [closed]

    - by Dan
    I'm trying to create a word scramble game and so far I have taken a vector of randomly assorted strings that contains both words and hints and split them into two vectors. I have randomly scrambled the word and set this all up in text boxes. Right now I'm stuck because I have a text box that takes input but I'm not sure how to read that in? I want the user to type the unscrambled word into the text box and have it calculate as correct and move on to the next word immediately. I also don't know how to get the keys working. I want the "?" character to be the hint button that shows the hint. At the moment the hint box works if I type the question mark in using the System.in but it doesn't work if I type it directly in to the text box. The characters are showing up in the text box but nothing is working after that.

  • Drawing on a webpage – HTML5 - IE9

    - by nmarun
    So I upgraded to IE9 and continued exploring HTML5. Now there’s this ‘thing’ called Canvas in HTML5 with which you can do some cool stuff. Alright what IS this Canvas thing anyways? The Web Hypertext Application Technology Working Group says this: “The canvas element provides scripts with a resolution-dependent bitmap canvas, which can be used for rendering graphs, game graphics, or other visual images on the fly.” The Canvas element has two only attributes – width and height and when not specified they take up the default values of 300 and 150 respectively. Below is what my HTML file looks like: 1: <!DOCTYPE html> 2: <html lang="en-US"> 3: <head> 4: <script type="text/javascript" src="CustomScript.js"></script> 5: <script src="jquery-1.4.4.js" type="text/javascript"></script 6:  7: <title>Draw on a webpage</title> 8: </head> 9: <body> 10: <canvas id="canvas" width="500" height="500"></canvas> 11: <br /> 12: <input type="submit" id="submit" value="Clear" /> 13: <h4 id="currentPosition"> 14: 0, 0 15: </h4> 16: <div id="mousedownCoords"></div> 17: </body> 18: </html> In case you’re wondering, this is not a MVC or any kind of web application. This is plain ol’ HTML even though I’m writing all this in VS 2010. You see this is a very simple, ‘gimmicks-free’ html page. I have declared a Canvas element on line 10 and a button on line 11 to clear the drawing board. I’m using jQuery / JavaScript show the current position of the mouse on the screen. This will get updated in the ‘currentPosition’ <h4> tag and I’m using the ‘mousedownCoords’ to write all the places where the mouse was clicked. This is what my page renders as: The rectangle with a background is our canvas. The coloring is due to some javascript (which we’ll see in a moment). Now let’s get to our CustomScript.js file. 1: jQuery(document).ready(function () { 2: var isFirstClick = true; 3: var canvas = document.getElementById("canvas"); 4: // getContext: Returns an object that exposes an API for drawing on the canvas 5: var canvasContext = canvas.getContext("2d"); 6: fillBackground(); 7:  8: $("#submit").click(function () { 9: clearCanvas(); 10: fillBackground(); 11: }); 12:  13: $(document).mousemove(function (e) { 14: $('#currentPosition').html(e.pageX + ', ' + e.pageY); 15: }); 16: $(document).mouseup(function (e) { 17: // on the first click 18: // set the moveTo 19: if (isFirstClick == true) { 20: canvasContext.beginPath(); 21: canvasContext.moveTo(e.pageX - 7, e.pageY - 7); 22: isFirstClick = false; 23: } 24: else { 25: // on subsequent clicks, draw a line 26: canvasContext.lineTo(e.pageX - 7, e.pageY - 7); 27: canvasContext.stroke(); 28: } 29:  30: $('#mousedownCoords').text($('#mousedownCoords').text() + '(' + e.pageX + ',' + e.pageY + ')'); 31: }); 32:  33: function fillBackground() { 34: canvasContext.fillStyle = '#a1b1c3'; 35: canvasContext.fillRect(0, 0, 500, 500); 36: canvasContext.fill(); 37: } 38:  39: function clearCanvas() { 40: // wipe-out the canvas 41: canvas.width = canvas.width; 42: // set the isFirstClick to true 43: // so the next shape can begin 44: isFirstClick = true; 45: // clear the text 46: $('#mousedownCoords').text(''); 47: } 48: })   The script only looks long and complicated, but is not. I’ll go over the main steps. Get a ‘hold’ of your canvas object and retrieve the ‘2d’ context out of it. On mousemove event, write the current x and y coordinates to the ‘currentPosition’ element. On mouseup event, check if this is the first time the user has clicked on the canvas. The coloring of the canvas is done in the fillBackground() function. We first need to start a new path. This is done by calling the beginPath() function on our context. The moveTo() function sets the starting point of our path. The lineTo() function sets the end point of the line to be drawn. The stroke() function is the one that actually draws the line on our canvas. So if you want to play with the demo, here’s how you do it. First click on the canvas (nothing visible happens on the canvas). The second click draws a line from the first click to the current coordinates and so on and so forth. Click on the ‘Clear’ button, to reset the canvas and to give your creativity a clean slate. Here’s a sample output: Happy drawing!
