• Selecting pictures with Jquery and Javascript

  - by Axschech

  I'm testing out a layout on a website using 3 pictures here: Schechterbusiness.info the left button works, making it go through the pictures. But I can't figure out how to get the right button to work, which is supposed to scroll through the other way. I know there's probably a way to do it with arrays but I can't wrap my brain around it. Halp! Code to scroll through pictures: $('#fryLink').click(function() { $('#hide').hide(); $('#img').hide(); count++; if(count == 1) { $('#img').attr("src","images/fry.png"); } else if(count == 2) { $('#img').attr("src","images/bender.png"); } else if(count == 3) { $('#img').attr("src","images/zoidberg.png"); } $('#img').show("fade"); if(count > 2) { count = 0; }

• drag to pan on an UserControl

  - by Matías

  Hello, I'm trying to build my own "PictureBox like" control adding some functionalities. For example, I want to be able to pan over a big image by simply clicking and dragging with the mouse. The problem seems to be on my OnMouseMove method. If I use the following code I get the drag speed and precision I want, but of course, when I release the mouse button and try to drag again the image is restored to its original position. using System.Drawing; using System.Windows.Forms; namespace Testing { public partial class ScrollablePictureBox : UserControl { private Image image; private bool centerImage; public Image Image { get { return image; } set { image = value; Invalidate(); } } public bool CenterImage { get { return centerImage; } set { centerImage = value; Invalidate(); } } public ScrollablePictureBox() { InitializeComponent(); SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.OptimizedDoubleBuffer, true); Image = null; AutoScroll = true; AutoScrollMinSize = new Size(0, 0); } private Point clickPosition; private Point scrollPosition; protected override void OnMouseDown(MouseEventArgs e) { base.OnMouseDown(e); clickPosition.X = e.X; clickPosition.Y = e.Y; } protected override void OnMouseMove(MouseEventArgs e) { base.OnMouseMove(e); if (e.Button == MouseButtons.Left) { scrollPosition.X = clickPosition.X - e.X; scrollPosition.Y = clickPosition.Y - e.Y; AutoScrollPosition = scrollPosition; } } protected override void OnPaint(PaintEventArgs e) { base.OnPaint(e); e.Graphics.FillRectangle(new Pen(BackColor).Brush, 0, 0, e.ClipRectangle.Width, e.ClipRectangle.Height); if (Image == null) return; int centeredX = AutoScrollPosition.X; int centeredY = AutoScrollPosition.Y; if (CenterImage) { //Something not relevant } AutoScrollMinSize = new Size(Image.Width, Image.Height); e.Graphics.DrawImage(Image, new RectangleF(centeredX, centeredY, Image.Width, Image.Height)); } } } But if I modify my OnMouseMove method to look like this: protected override void OnMouseMove(MouseEventArgs e) { base.OnMouseMove(e); if (e.Button == MouseButtons.Left) { scrollPosition.X += clickPosition.X - e.X; scrollPosition.Y += clickPosition.Y - e.Y; AutoScrollPosition = scrollPosition; } } ... you will see that the dragging is not smooth as before, and sometimes behaves weird (like with lag or something). What am I doing wrong? I've also tried removing all "base" calls on a desperate movement to solve this issue, haha, but again, it didn't work. Thanks for your time.

• Spring Transaction Manager

  - by cedric

  Hi. I have a j2ee application running on spring framework. I am implementing a transaction manager with AOP. It works fine. When an exception occurs in my method it is detected by my AOP configuration and rolls back the changes in the DB. But the problem is the code where you expect the error should not be surrounded with try-catch. When I suround it with try-catch it won't roll-back. But I need to do some stuffs like logging whenever there are errors and the only place I can think of placing it is in the catch block.

• animate rotation

  - by Mike

  I'm trying to animate a rotation using CATransform3DMakeRotation, but the problem is once the animation is finished, the image goes back to its initial position, i.e back to zero. But I'd like to keep it where it finished rotating. How would I do that? edit What I'm trying to do is to create the same compass which comes with the new iPhone. Basically the locationmanager gives me new headings every few seconds (or several per second). Using the new heading and the timestamp, I was trying to get a smooth animation of the image but not getting anywhere. The only thing which seems to work is applying the transform directly, e.g. compassimage.layer.transform = CATransform3DMakeRotation(newHeading.trueHeading *M_PI/180,0,0,1.0): but that's not animated...

• UISplitViewController: how to get toolbar if details controller is UITableView?

  - by Krumelur

  Hi, I checked out Apple's example on how to exchange detail views in the UISplitViewController (http://developer.apple.com/library/ios/#samplecode/MultipleDetailViews/Introduction/Intro.html#//apple_ref/doc/uid/DTS40009775) and it seems that they put the UIToolbar in every detail controller. Then, if the device is rotated, they hide the toolbar or show it and add a popover button which will show the root controller. I'd like to adopt this pattern to show my root controller in a popover using a button in the toolbar, but unfortunately, my detail controllers are all UITableViewControllers and they do not allow adding other UI elements than a table view. So how do I deal with that? Is there an example around? René

• Adding a mini admin to a webpage.

  - by DADU

  Hello Picture this: you are creating a little module that people can incorporate into their website easily, for example, a little contact form. It would consist of a PHP file that outputs some HTML, a Javascript file (ajax etc.), a CSS file and a CSS skin. Now the person who doesn't know much about coding wants to integrate it on a webpage (website/index.php). We could do this with three rules of code: <link rel="stylesheet" href="module/css/module.css" /> <script src="module/js/module.js"></script> <?php require_once 'module/module.php'; ?> There's no doubt this part is questionable, right? Now when we want to add an admin for this little module, there are two options: Accessing the admin via an extra URL like website/module/admin.php and after authentication, displaying a page where the person can do all the settings. The person then goes back to index.php to see the results. Enabling the admin via an extra URL like website/module/admin.php and after authentication, redirecting back to index.php. The person can now edit the module directly (HTML5 contenteditable) and see changes live, on the webpage where everybody else will see it when the person saves the changes. Option 2 has a couple of advantages: The person doesn't have to toggle between admin and index.php. The person can see directly how it's looking at the webpage it's integrated in. The person probably feels like the module is more part of the webpage/website. Of course option 2 has some disadvantages too: Not everything works well editing it inline. The person would need to have an HTML5 compliant browser. Probably some more I can't think of right now. Now I have a few concerns that's I can't seem to see a clear answer to. How would we let the person integrate the admin on their webpage? The admin files only need to be included in index.php if the person has choosen to edit the module via the url (website/module/admin.php). But how can we do this if we have a admin.css file that belongs in the head section, an admin.php file that goes into the body, and another admin.js file that's included at the end of the body? How would we know the file that admin.php needs to redirect back to, after authentication? index.php could be any webpage with any name. Any real life website/web apps examples using this principle are welcome too. If there's something unclear, I am glad to add additional info.

• HttpServletResponse XML to Java

  - by Mike

  I am maintaining this servlet that has a HttpServletResponse response that replies back to the client an XML message. I want to take the XML message and convert it to JSON, then send the JSON back. I want to avoid writing my own JSON converter if possible. Does anyone have a good method of doing this? I googled for this: http://pvoss.wordpress.com/2009/02/26/servlet-filter-to-convert-xml-to-json/ , which is exactly what I want but they are using a hacked dom4j jar which doesn't help me.

• git filter-branch chmod

  - by Evan Purkhiser

  I accidental had my umask set incorrectly for the past few months and somehow didn't notice. One of my git repositories has many files marked as executable that should be just 644. This repo has one main master branch, and about 4 private feature branches (that I keep rebased on top of the master). I've corrected the files in my master branch by running find -type f -exec chmod 644 {} \; and committing the changes. I then rebased my feature branches onto master. The problem is there are newly created files in the feature branches that are only in that branch, so they weren't corrected by my massive chmod commit. I didn't want to create a new commit for each feature branch that does the same thing as the commit I made on master. So I decided it would be best to go back through to each commit where a file was made and set the permissions. This is what I tried: git filter-branch -f --tree-filter 'chmod 644 `git show --diff-filter=ACR --pretty="format:" --name-only $GIT_COMMIT`; git add .' master.. It looked like this worked, but upon further inspection I noticed that the every commit after a commit containing a new file with the proper permissions of 644 would actually revert the change with something like: diff --git a b old mode 100644 new mode 100755 I can't for the life of me figure out why this is happening. I think I must be mis-understanding how git filter-branch works. My Solution I've managed to fix my problem using this command: git filter-branch -f --tree-filter 'FILES="$FILES "`git show --diff-filter=ACMR --pretty="format:" --name-only $GIT_COMMIT`; chmod 644 $FILES; true' development.. I keep adding onto the FILES variable to ensure that in each commit any file created at some point has the proper mode. However, I'm still not sure I really understand why git tracks the file mode for each commit. I had though that since I had fixed the mode of the file when it was first created that it would stay that mode unless one of my other commits explicit changed it to something else. That did not appear to the be the case. The reason I thought that this would work is from my understanding of rebase. If I go back to HEAD~5 and change a line of code, that change is propagated through, it doesn't just get changed back in HEAD~4.

• Carrierwave upload to a tmp dir before saving to database

  - by user827570

  I'm trying to build a visual editor where users can click an image they are presented with an image upload form once the upload is done I use ajax to return the image and insert it back into the page. But the above method inserts the image straight into the database but I want users to be able to visualize the image before the image is inserted into the database. So I was wondering if the image using carrierwave could be uploaded to a temp location, sent back to the user and then when the user saves the page the image is moved into the permanent location. Here's what I have so far. def edit_image @page = Page.find(1) @page.update_attributes(params[:page]) @page.save return :text => @page.file end But this is what I want to achieve def temp_image #uploads received image to a temp location #returns image to the user end And once the user clicks save def save #moves the file in the temp folder to the permanent location end Cheers

• Transform.Translation problem on rotation

  - by eco_bach

  I am using the following to scale and reposition a UIView layer when the device rotates to landscape. [containerView.layer setValue:[NSNumber numberWithFloat: 0] forKeyPath: @"transform.translation.x"]; [containerView.layer setValue:[NSNumber numberWithFloat: 0] forKeyPath: @"transform.translation.y"]; [containerView.layer setValue:[NSNumber numberWithFloat: 1] forKeyPath: @"transform.scale.x"]; //[NSNumber numberWithInt:1] [containerView.layer setValue:[NSNumber numberWithFloat: 1] forKeyPath: @"transform.scale.y"]; and then the folowing when rotating back to portrait [containerView.layer setValue:[NSNumber numberWithFloat: -75] forKeyPath: @"transform.translation.x"]; [containerView.layer setValue:[NSNumber numberWithFloat: 0] forKeyPath: @"transform.translation.y"]; [containerView.layer setValue:[NSNumber numberWithFloat: .7] forKeyPath: @"transform.scale.x"]; //[NSNumber numberWithInt:1] [containerView.layer setValue:[NSNumber numberWithFloat: .7] forKeyPath: @"transform.scale.y"]; The problem is that after rotaing back to portrait, the layer is 'travelling' ie the x,y offset are gradually changing(increasing x, decreasing y). Scale seems fine (ie doesn't increment, decrement on repeated rotations) Can anyone suggest a proper solution?

• How can I launch a missile?

  - by doug.stanhope

  I am working on an open-source missile launcher application. I have added a big red button to a Form that says "Launch Missile". When I click the button, the event handler gets called. From the event handler I call a method named LaunchMissile(). So far so good, but how do you launch a missile from C# code? Will I have to write this code myself or is there an API or third party library for launching missiles? Please add sample code for various launch scenarios: orbit, moon, mars, etc.

• How to Detect a Right Click on Taskbar in WPF

  - by Zay

  I've got a WPF application in C# that starts off with a loading dialog. As expected, a button for the app shows up in the Windows taskbar. I would like to detect right-clicks that might be done to that button. Ultimately, I hope to disable the right-click or simply have the loading dialog regain focus. I've seen that some people use custom libraries and packages (interop, for example) to achieve some Win32 functionality, but I'd personally like to avoid this. Furthermore, these libraries/packages appear to be specific to Windows Forms; I've not seen anything for WPF. Is it impossible to manipulate the taskbar's right-click in WPF?

• Python/Tkinter Audio Player

  - by Nicholas Quirk

  Hey everyone reading this, I've recently got into doing GUI development with Python. Tkinter seems like the easiest and most logical choice starting out. I did a little with wxPython but it was more sophisticated than what I needed. Anyway, I'm developing a media player. Right now it's a simple window with a button to load .wav files. The problem is I would like to implement a pause button now. But, when playing a audio file the GUI isn't accessible again (no buttons can be pushed) till the file is done playing. How can I make the GUI dynamic while an audio file is playing? I was thinking this maybe be because I'm using PyAudio, and their implementation doesn't allow this. Anyway, thanks for any advice before hand.

• Passing Info From One View to Another

  - by 01010011

  EDIT 1. The results of a query from my database are displayed on my view page. Next to each unique result is a button: // first_view.php <?php echo form_open('controller/method'); ?> <?php foreach($results_found as $item): ?> <p><?php echo $item->name ?></p> <p><?php form_submit('buy','Buy This'); ?></p> When a user clicks on one of these buttons (lets say button 4), I would like to display the user's choice from the array onto another view. I've tried using this: // first_view.php <?php echo $this->session->set_userdata('choice',$item); ?> immediately before // first_view.php <?php echo form_close(); ?> thinking that the user's final choice would be stored there so I can display it on another view like this: // second_controller.php $c = $this->session->userdata('choice'); // second_view.php echo 'Your Choose: '. $c; However, what actually displays is the last result displayed on first_view.php, not what the user choose. My question is, if the user clicked on button 4, how do I get that particular choice displayed onto another view? END OF EDIT1 ORIGINAL QUESTION My view page (CodeIgniter) displays the contents of an array in the form of several links. If a user clicks on a link, I want the user to be taken to another view page (via a controller) that gives more information concerning that particular link (which is stored in that particular position in the array) My question is, how do I access and display the contents of that particular location within the array on the second view file without getting a "Undefined variable error" on the second view? Here is what I am trying to do in code form // my_controller.php $array_name['variable_name']; $this->load->view('first_view.php'); // first_view.php <?php foreach($variable_name as $vn): ?> <?php echo anchor('controller_name' $vn->info ?> // if user clicks on 3rd link <?php endforeach ?> // I want to beable to access // index 2 of the array in the // second view file so I can // display more info // second_view.php <?php $vn[2]->info ?>

• table cell background color change problem

  - by Mellon

  I work on another guy's code, and I try to change the table cell background color when mouse over the cell, and change back to the original background color when mouse leave. I use the following code: var bgcolor=$(".cell-el").css("background-color") $(".cell-el").hover( function(){ $(this).css("background-color", "#3c3c36")}, //mouse enter, bg-color change function(){ $(this).css("background-color", bgcolor) // mouse leave, bg-color change back }) Things are working fine, EXCEPT that when mouse first time enter the cell, the cell background color is not changed to "#3c3c36", but when mouse leave the cell after first entering and enter in the cell again, the cell's background color changed to "#3c3c36". That's the cell color never change for mouse first enter, after that, everything is working great. What's could be the cause of this problem?

• Django: How do I position a page when using Django templates

  - by swisstony

  I have a web page where the user enters some data and then clicks a submit button. I process the data and then use the same Django template to display the original data, the submit button, and the results. When I am using the Django template to display results, I would like the page to be automatically scrolled down to the part of the page where the results begin. This allows the user to scroll back up the page if she wants to change her original data and click submit again. Hopefully, there's some simple way of doing this that I can't see at the moment.

• accessing google maps via UIWebView - illegal?

  - by Karin

  New to iPhone development. Working on first app. I'm accessing google maps via UIWebView to forward geocode an address using "http://maps.google.com/maps?q=my address". It works, although it has this quirk of requiring you to hit "Back" button and then the "Detail" button (provided by the navigation bar) to get back to the screen from whence you started. If anyone knows why it does this, I'd love to hear. My real question, however, is this a legal use of google maps? Since I intend this app for commercial use, am I violating Google's rules + regs? If it is illegal, what's my alternative? Thanks.

• C# Changing a constant

  - by Jane T

  I have inherited a small windows form based program written in C# that uses a 'constant' (See below), I need to modify this program so 'PROPERTY_NAME' can be "jobs" and "careers". private const string PROPERTY_NAME = "jobs"; I'm guessing a constant isn't designed to change so should I need to change this. The line above is set once at the top of a class file and then PROPERTY_NAME is used throughout that file. On the main form I would like to add two radio buttons 1 called 'jobs' and one called 'careers' and then change the PROPERTY_NAME in the class file based on which is selected. Would I need to pass the radio button status to the method in the class file? I recall reading that I can't simply read the radio button value from the class file. Many thanks for your advice. Jane
