  • When going for an interview for web development at an agency, can a real example be expected?

    - by KPO
    I just started coding a year ago. By "coding" I mean HTML(5), CSS(3), and only a few times I implemented AJAX and JavaScript. I am interviewing for a position that expects me to know HTML, CSS, JS, JQuery, and AJAX. I am good with HTML5/CSS3 and somewhat ok with js. If I go for an interview, will they expect me to write code during the interview? I do have a live website as an example and snapshots of past projects that I sent to them. I am a little nervous, so any tips or something from your experience I can learn will be helpful.

  • Setting a DataGrid background color based on the previous row

    - by Zipper
    I'm trying to setup a grid where I do column sorting, but I wanted to do zebra striping, only rather than every other row or every x rows, I want it to be based on the value of cells. i.e. All cells that contain 0 have a blue background, the next value would have a white background, the next value would be blue, etc.... The problem I have is that I can't seem to find where to actually do the setting of the background colors. I'm using a custom sorter and I tried setting it in there after I re-order the list and set the data source, but it appears that when the data source is set, that the rows don't exist yet. I tried using the DataContextChanged, but that event doesn't seem to be firing. Here is what I have now. namespace Foo.Bar { public partial class FooBar { List<Bla> ResultList { get; set; } SolidColorBrush stripeOneColor = new SolidColorBrush(Colors.Gold); SolidColorBrush stripeTwoColor = new SolidColorBrush(Colors.White); //********************************************************************************************* public Consistency() { InitializeComponent(); } //********************************************************************************************* override protected void PopulateTabWithData() { ResultList = GetBlas(); SortAndGroup("Source"); } //********************************************************************************************* private void SortAndGroup(string colName) { IOrderedEnumerable <Bla> ordered = null; switch (colName) { case "Source": case "ID": ordered = ResultList.OrderBy(r => r.Source).ThenBy(r => r.ID); break; case "Name": ordered = ResultList.OrderBy(r => r.Source).ThenBy(r => r.Name); break; case "Message": ordered = ResultList.OrderBy(r => r.Message); break; default: throw new Exception(colName); } ResultList = ordered.ThenBy(r => r.Source).ThenBy(r => r.ID).ToList(); // tie-breakers consistencyDataGrid.ItemsSource = null; consistencyDataGrid.ItemsSource = ResultList; ColorRows(); } //********************************************************************************************* private void consistencyDataGrid_Sorting(object sender, System.Windows.Controls.DataGridSortingEventArgs e) { SortAndGroup(e.Column.Header.ToString()); e.Handled = true; } private void ColorRows() { for (var i = 0; i < ResultList.Count; i++) { var currentItem = ResultList[i]; var row = myDataGrid.ItemContainerGenerator.ContainerFromItem(currentItem) as DataGridRow; if (row == null) { continue; } if (i > 0) { var previousItem = ResultList[i - 1]; var previousRow = myDataGrid.ItemContainerGenerator.ContainerFromItem(previousItem) as DataGridRow; if (currentItem.Source == previousItem.Source) { row.Background = previousRow.Background; } else { if (previousRow.Background == stripeOneColor) { row.Background = stripeTwoColor; } else { row.Background = stripeOneColor; } } } else { row.Background = stripeOneColor; } } } } } }

  • Would Like Multiple Checkboxes to Update World PNG Image Using Mogrify to FloodFill Countries With C

    - by socrtwo
    Hi. I'm seeing in another forum if the best way to do this is with Javascript or Ajax but I'm wondering if there is an even easier simpler way. I'm trying to create a web service where users can check which countries they have visited from a list of 175 or so and a World map image would then instantly update with a filled color. There are other similar services, but I'm envisioning mine to be both updating from checks in checkboxes and by clicking on the target country in the displayed image say with an imagemap. Additionally other solutions display all the visited countries in the same color. I would like different colors for different countries or at least for those countries that touch. Eventually I would like to include a feature that enables the choice of which colors to assign countries. I found a Sourceforge project called pwmfccd. It's simply an open source image of the world and the coordinates on the PNG image for all the countries. You can use mogrify from ImageMagick and floodfill to fill the countries with color. I have done this successfully, locally with batch files. My ISP has told me where mogrify is located, basically "/usr/bin/mogrify". I now have a horrendously complicated cgi script which if it worked is set to redraw the world map image with each checkbox. It's here. It also redraws the whole web page with each check. The web page starts here. Of course this is not at all efficient, and I think probably the real way to go is Ajax or Javascript, so that maybe just the image gets changed and redrawn, not the whole web page. Sorry I don't even know the difference between Javascript and Ajax and their relative merits at this point. I suppose you could make just one part of the image update with each check or click on the image instead of even just the image redrawing, but I have never even heard of a hint at being able to do that for irregularly shaped image elements like countries. So I guess an Image map and sister checkbox entries tied to mogrify events redrawing the user's personal copy of the image with an image refresh would be the only way to go. So how do you do this with something other than Javascript or Ajax or is that definitely the way to go and if so, how would you do it? Or can you after all cut up a web based image into irregular puzzle shaped piece which you can redraw individually at will. Thanks in advance for reading and considering answering this post.

  • Why doesn't this image sprite menu display properly, and why aren't the links working?

    - by briligg
    The code validates. There should be two more images in the menu on the left, above the visible one of the silo. And each should be a link. http://www.briligg.com/agnosticism.html css is: external style sheet: .menu { position: relative; float: left; margin: 10px; padding: 0; width: 150px; } .menu li { margin: 0; padding: 0; list-style: none; position: absolute; left: 0; top: 260px; } .menu li, .menu a { width: 150px; height: 150px; } internal style sheet: .menu { height: 450px; } .mirror { top: 0; } .mirror { background: url(http://www.briligg.com/images/menu-ag.png) 0 0; } .wormcan { top: 151px; } .wormcan { background: url(http://www.briligg.com/images/menu-ag.png) 0 -151px; } .wormsilo { top: 301px; } .wormsilo { background: url(http://www.briligg.com/images/menu-ag.png) 0 -301px; } html: <ul class="menu"> <li class="mirror"> <a href="whoryou.html"></a> </li> <li class="wormcan"> <a href="aroundyou.html"></a> </li> <li class="wormsilo"> <a href="beyondyou.html"></a> </li> </ul>

  • Facebook Connect for iPhone: How to upload an image (UIImage) to user's wall without having to use j

    - by Crowem
    Is there any way to upload an image (UIImage) directly from an iPhone app to a user's wall/feed? All the samples I see are either using a json-embedded link or they use the photos.upload call with album ID (aid) which results in the user getting the image in his photo album(s). What I want to do is to upload an (UI)Image created (by the user) inside an iPhone app and upload to his/her wall. Is this possible? Sample code would be highly appreciated.

  • How to select and crop an image in android?

    - by Guy
    Hey, I am currently working on a live wallpaper and I allow the user to select an image which will go behind my effects. Currently I have: Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); i.putExtra("crop", "true"); startActivityForResult(i, 1); And slightly under that: @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if (requestCode == 1) if (resultCode == Activity.RESULT_OK) { Uri selectedImage = data.getData(); Log.d("IMAGE SEL", "" + selectedImage); // TODO Do something with the select image URI SharedPreferences customSharedPreference = getSharedPreferences("imagePref", Activity.MODE_PRIVATE); SharedPreferences.Editor editor = customSharedPreference.edit(); Log.d("HO", "" + selectedImage); editor.putString("imagePref", getRealPathFromURI(selectedImage)); Log.d("IMAGE SEL", getRealPathFromURI(selectedImage)); editor.commit(); } } When my code is ran, Logcat tells me that selectedImage is null. If I comment out the i.putExtra("crop", "true"): Logcat does not give me the null pointer exception, and I am able to do what I want with the image. So, what is the problem here? Does any one have any idea how I can fix this? Thanks, for your time.

  • Problem in Setting image in imageview inside ListView in Android?

    - by sunil
    Hi, I have a listview which includes 2 textviews and 1 imageview. Now, the image in imageview will be set on certain conditions otherwise it should be left blank with no image. The problem is the images are not coming in proper rows. Say, for eg the image should be displayed at row 3 but its displayed at row 4. And, in some cases each row will have the same image. Has someone faced this kind of an issue? I am really clueless about the reason behind this. Can anyone point out the problem? Regards Sunil

  • Background problem of opengl 3d object over iphone camera view

    - by user292127
    Hi, I'm loading opengl 3d objects over the iphone camera view. When opengl view is loaded it's loading with a opengl 3d object with black background. The black background color will block the camera view.I just want to clear background color of opengl view so that I could load only the 3d object to the camera view. I had tried glclearcolor(1.0,1.0,1.0,0.0); but no change to background color. I had also tried to clear background color opengl view using [glview setbackgroundColor:[UIColor clearColor]];. No change in back ground color. Can any one help me with this stuff ? I'm new to opengl. Thanks in advance

  • How can I set a highlighted image on a table view cell?

    - by nevan
    I've followed the code in Apple's AdvancedTableViewCells and built a table view with a background image for cells. Now I want to change it so that instead of the blue highlight colour, it shows a darker version of my image. What are the steps I need to follow to do this? I'm using a UITableViewCell subclass with a custom NIB. My background image is implemented as the cell.backgroundView. The steps I've take so far are: Change the selectionStyle of the cell to "None" Set the Highlight colour on my UILabel subviews to a light colour Create a darker version of my background as a separate image Override setSelected: animated: I'm wondering about the next steps.

  • In Flex 3 is there a way to pre-buffer an image so that it appears without flickering?

    - by Brad Urani
    In my application I have an VBox control on top of another VBox that contains an Image control that loads a jpg from a URL (you can't see the bottom panel initially since it's underneath, but the image does fully download). When one clicks on the top VBox, the bottom one gets set to visible=false, then an effect causes the top VBox to vanish, then the bottom VBox is set to visible=true and an effect causes it to appear. Continuously clicking the VBoxes causes them to alternate appearing and disappearing. The problem is that the first time the bottom VBox appears, it flickers once when it draws. After that, there's no problem and it smoothly appears and disappears with the effect with no problem. It's as if the first time the bottom VBox appears, it flickers because even though the image has been downloaded, it has never been displayed before. Can I pre-buffer the image in the bottom VBox somehow to avoid this flicker?

  • How to make an image randomizer from gallery directory?

    - by zebraman
    Hello, I would like to make a image randomizer/slider that randomly displays an image from a designated gallery and has controls to view the next/previous image. I have seen this done where images must be coded into arrays, but I would like to be able to just drop images into a /img/gallery directory and have the randomizer/slider pull random images from that directory. Could anyone offer some guidance on how to do this, possibly using jQuery, or refer me to a tutorial that does something like this?

  • Change color of a table cell using javascript using dropdown menu

    - by Mike Burzycki
    I'd like to use some javascript code to change the background color of a single cell within a table. I have some code below which allows me to change the page background color. This is similar in concept to what I would like to do, but I would really like to be able to change just one cell...not the whole page. I have thought about making the rest of the cell borders and background colors white, leaving the cell I want to manipulate transparent, but I think this probably a brute force method that will cause me trouble down the road. Does anyone have any advice to do this with javascript? The page background color changing code is here: <form name="bgcolorForm">Try it now: <select onChange="if(this.selectedIndex!=0) document.bgColor=this.options[this.selectedIndex].value"> <option value="choose">set background color <option value="FFFFCC">light yellow <option value="CCFFFF">light blue <option value="CCFFCC">light green <option value="CCCCCC">gray <option value="FFFFFF">white </select></form> Thanks for the help, Mike

  • Drupal-- How to place an image in Panels 3 panels and mini-panels, w/o views or nodes?

    - by msumme
    Is it possible, through any modular functionality, to insert an image into a (mini-)panel, either through token replacement, or through an upload dialog, or through a file selection menu? Do I have to use views? Do I have to create nodes? Would the best way be to make a panel node, and then embed it in a mini-node, if I want a block-like panel that can be placed on multiple pages? I want to build a site with images in a particular layout as a small block, and make it very easy for my client to change those images in the future. I can think of some other ways to make this work, but it's driving me crazy that there seems to be no way to simply PUT an image in a mini-panel without having to upload it and hard-code an image tag. And since my client knows no HTML, coding it this way makes it un-helpful for him. And this mini-panel block is going to be used on a number of pages, and needs to be easily modified. I have been googling for about 45 minutes, and come up with nothing useful. EDIT: OR EVEN just put ONLY one image from an image field w/ multiple values in a panel region on a panel node?

  • iPhone: cached profile images from the web - how to find out that remote image changed?

    I'm loading profile pictures from Facebook, cache them on disk and load them into cells of a UITableView. Now I'm wondering, how I can find out when someone has changed his/her profile picture on Facebook that I have to load the new image from the web instead of using the one cached disk. The url of the image is always the same. Is there a lightweight way of doing this without downloading the image and comparing it to the local file?
