  • How do I sanitize a string in PHP that contains "; Echo"? (I have a solid reason)

    - by user337878
    I turned this case into a simple PHP page that submits to itself. My issue is that I am submitting track meet results and one of the girl's names is Echo...a lovely name. The problem text I'm submitting is: Pole vault - Rachel Simons, Tow, 8-6; Echo Wilson, Cit, 8-0; Molly Randall, Tow, 7-0; So you see a semicolon followed by white space followed by Echo... After submitting, it says: POST to /results/test.php not supported The end goal is to save it to a database along with some other info and have a search page to find it and simply print out the full result on the screen. I stripped out all my database stuff to get it down to this one error. I mean, I can intentionally mis-spell her name, but there's gotta be a way around this, right??? Here's the test PHP file. <html> <head> <title>title</title> </head> <body> <?php echo "<h3>Edit meet info below</h3>"; echo "<form action=\"test.php\" method=\"post\" id=\"submitForm\">"; echo "Full Results:<br/><textarea NAME=\"results\" id=\"results\" rows=\"20\" cols=\"80\" MAXLENGTH=\"8191\"></textarea><br/><br/>"; echo "<input type=\"submit\" name=\"submitMeet\" value=\"Submit\">"; echo "</form>"; ?> </body> </html>

  • App hosting Report Viewer crashes on exit after export

    - by Paul Sasik
    We have a .NET Winforms application that hosts the Crystal Reports Viewer control (Version XI). It works well for the most part but when an export of data from the viewer is performed the application will crash on exit and in unmanaged code. The error message is not very useful and just says that an incorrect memory location was accessed. No other info such a specific DLL etc. is provided. This only happens after the viewer is used to export a report to CSV, XML etc. My guess is that at some point in the export process Crystal creates a resource that attempts an action on shut down to a parent window (perhaps) that no longer exists. I've seen a number of memory leak and shut down issues with Crystal but this one's new. Has anyone seen it and come up with a workaround or has ideas for workarounds? So far we've tried explicitly disposing of all crystal-related objects, setting to null and even setting a Thread.Sleep cycle on shut down to "give Crystal time to clean up." Update: The crash happens only on shut down (so not immediate) All export formats work All export files are created properly CR is installed on the same machine as the hosting .NET app not sure about exporting from the IDE... is that even possible?

  • How to remove an object from the canvas?

    - by Marius Jonsson
    Hello there, I am making this script that will rotate a needle on a tachometer using canvas. I am a newbie to this canvas. This is my code: function startup() { var canvas = document.getElementById('canvas'); var context = canvas.getContext('2d'); var meter = new Image(); meter.src = 'background.png'; var pin = new Image(); pin.src = 'needle.png'; context.drawImage(meter,0,0); context.translate(275,297); for (var frm = 0; frm < 6000; frm++){ var r=frm/1000; //handle here var i=r*36-27; //angle of rotation from value of r and span var angleInRadians = 3.14159265 * i/180; //converting degree to radian context.rotate(angleInRadians); //rotating by angle context.drawImage(pin,-250,-3); //adjusting pin center at meter center } } Here is the script in action: http://www.kingoslo.com/instruments/ The problem is, as you can see, that the red needle is not removed beetween each for-loop. What I need to do is to clear the canvas for the pin object between each cycle of the loop. How do I do this? Thanks. Kind regards, Marius

  • Providing lat/long AND title in iOS Maps URL seems to cause zoom level to be ignored

    - by Ian Howson
    I'm writing an iOS app that shows a location in Maps upon a user action. I'd like to drop a pin with a description and zoom in to show map detail. If I invoke Maps with the url http://maps.google.com/maps?q=-33.895851,151.18483+(Some+Description)&z=19 I get a pin with 'Some Description', but the zoom level is ignored. This does work on the Google Maps website. If I use http://maps.google.com/maps?q=-33.895851,151.18483&z=19 the zoom works, but I get no pin. I've tried a few combinations of ?q=, ?ll= and ?sll=, but so far, nothing will change zoom and show a description. Any clues? Just so we're really clear, here are some screenshots. I want this to work on a real device (i.e. with iOS Maps). The simulator uses Google Maps through Safari. Here's what I see with URL 1 ([[UIApplication sharedApplication] openURL:[NSURL URLWithString: @"http://maps.google.com/maps?q=-33.895851,151.18483+(Some+Description)&z=19"]];) This is URL 2 ([[UIApplication sharedApplication] openURL:[NSURL URLWithString: @"http://maps.google.com/maps?q=-33.895851,151.18483&z=19"]];): This is relikd's suggestion ([[UIApplication sharedApplication] openURL:[NSURL URLWithString: @"http://maps.google.com/maps?z=19&q=-33.895851,151.18483+(Some+Description)"]];): I want the image I see in screenshot 2, but with a pin and a description.

  • Swipe left/right to push next/previous details view

    - by Youssef
    I am working on a ios application, using storyboard. I have a simple table view with rows. Each row has a "key" string to identify it. When the user clicks on a row I push the next view "DetailsViewController" and pass the "key" as a parameter in the prepareForSegue method. The data in the second view will change based on the "key" passed. In the "DetailsViewController" I want to add a swipe gesture, when the user swipes right, I want to push the next details view. It will be as if he clicked on the next row in the table view. So to rephrase, the user has 2 ways of switching between items: he can click the item in the table view and the details view will show, he can then go back and select another item. Or he can click on a row, and in the details view he can swipe left and right to see the previous/next item. i added the uigesture recognizer: UISwipeGestureRecognizer *recognizer; recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipe:)]; [recognizer setDirection:UISwipeGestureRecognizerDirectionRight]; [[self view] addGestureRecognizer:recognizer]; - (void) handleSwipe:(UISwipeGestureRecognizer *) sender { //I want to go to the next item in the tableview } I hope I was clear. Thank you.

  • What is the PastryKit Framework?

    - by Kerrick
    I'm trying to find any information I can on the PastryKit Javascript Framework. It appears to be in use on the iPhone User Guide that is displayed on the iPhone itself in Mobile Safari, but I cannot find any documentation or API. If you want to see it in action, open Safari 4, set your user agent to iPhone 3 (In the Develop menu) and check out the guide. Overall, it seems to be a way to write an HTML/CSS/Javascript application that acts like a native iPhone app. When it comes to Javascript, I used the JS Beautifier on (what I assume to be) the framework file and it was over 3,400 lines! Beautified, (again what I assume to be) their implementation of it was over 1,200 lines. On the CSS side, I used Clean CSS on (again what I assume to be) the framework CSS, and it came out to over 700 lines. Their implementation was shy of 500. Does anybody have, or know where to find, any information, documentation, or APIs on PastryKit? Or, can anybody figure out how to implement it?

  • Work for huge company or small company that makes products for huge company?

    - by TheGambler
    I'm facing a career decision. I currently work for a huge, huge, huge company (this should bring 3-4 companies to mind) as a programmer. I work on a really big (3 million lines of code) J2EE web application. I've been out of college for 2 years and I pretty much know that big corporate life isn't for me. There is a career opportunity to work for a small company that has a lot of funding and huge potential to sell their main project to this huge company I work for.This company makes kiosk software and works with a nearby kiosk software company. The deal isn't done, but I would come straight in to work on this project. This would be more of a interactive media position and I would do the development in flash/action script. I personally think this will be more interesting work then what I do now. This company does have other clients right now, just not on the scale of this potential huge client. I was told that my initial salary would be equal to what I'm making now, but if we land this client it could go up a lot more. I have a wife and child which should and will play a part in my decision if I should take this job. We do though have family that if crap hit the fan we could live with until we got back on our feet. So with the information provided, does this sound like a good opportunity and should I take it? This is a huge decision and the reason I'm asking the question here is because there are a lot of people here that have probably faced this decision before.

  • How do I control the background color during the iPhone flip view animation transition?

    - by Rob S.
    I have some pretty standing flipping action going on: [UIView beginAnimations:@"swapScreens" context:nil]; [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.view cache:YES]; [UIView setAnimationDuration:1.0]; [self.view exchangeSubviewAtIndex:0 withSubviewAtIndex:1]; [UIView commitAnimations]; To Apple's credit, this style of animation is amazingly easy to work with. Very cool, and I've been able to animate transitions, flips, fades etc. throughout the app very easily. Question: During the flip transition, the background visible 'behind' the two views during the flip is white and I'd like it to be black. I've: Set the background of the containing view (self.view above) - no dice. I really thought that would work. Set the background of each view to black - no dice. I didn't think this would work although you give different things a shot to understand better :) Google'd like crazy; keep landing on Safari-related listings. Thanks in advance!

  • mediaelement.js play/pause on click controls don't work

    - by iKode
    I need to play and pause the video player if any part of the video is clicked, so I implemented something like: $("#promoPlayer").click(function() { $("#promoPlayer").click(function() { if(this.paused){ this.play(); } else { this.pause(); } }); ...but now the controls of the video won't pause/play. You can see it in action here(http://175.107.134.113:8080/). The video is the second slide on the main carousel at the top. I suspect I'm now getting 2 onclick events one from my code above and a second on the actual pause/play button. I don't understand how the actual video controls work, because when I inspect the element, I just see a tag. If I could differentiate the controls, then perhaps I might have figured out a solution by now. Anyone know how I should have done this, or is my solution ok. If my solutions ok, how do I intercept a click on the control, so that I only have one click event to pause / play? If you look on the media element home page, they have a big play button, complete with mouseOver, but I can't see how they have done that? Can someone else help?

  • UIButton receives touches at the wrong position after CABasicAnimaton applied

    - by Dmitry
    I need to add an animation to UIButton - simple moving animation. When I do this, the button moves, but the click area of that button remains at old position: UIButton *slideButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; [slideButton addTarget:self action:@selector(clicked:) forControlEvents:UIControlEventTouchUpInside]; [slideButton setFrame:CGRectMake(50, 50, 50, 50)]; [self.view addSubview:slideButton]; CABasicAnimation *slideAnimation = [CABasicAnimation animationWithKeyPath:@"position"]; [slideAnimation setRemovedOnCompletion:NO]; [slideAnimation setDuration:1]; [slideAnimation setFillMode:kCAFillModeBoth]; [slideAnimation setAutoreverses:NO]; slideAnimation.fromValue = [NSValue valueWithCGPoint:CGPointMake(50, 50)]; slideAnimation.toValue = [NSValue valueWithCGPoint:CGPointMake(100, 100)]; [slideButton.layer addAnimation:slideAnimation forKey:@"slide"]; I already saw an answer to change the frame of the button at the end of the animation (like here UIButton receives touchEvents at the wrong position after a CABasicAnimaton) But it's not my case because I should give possibility to user to click on the button while it's moving... Also, I can't use another approaches (like NSTimer) as a replacement for CABasicAnimation because I will have a complex path to move the object... Thanks for Your help!

  • Model-binding an object from the repository by several keys

    - by Anton
    Suppose the following route: {region}/{storehouse}/{controller}/{action} These two parameters region and storehouse altogether identify a single entity - a Storehouse. Thus, a bunch of controllers are being called in the context of some storehouse. And I'd like to write actions like this: public ActionResult SomeAction(Storehouse storehouse, ...) Here I can read your thoughts: "Write custom model binder, man". I do. However, the question is How to avoid magic strings within custom model binder? Here is my current code: public class StorehouseModelBinder : IModelBinder { readonly IStorehouseRepository repository; public StorehouseModelBinder(IStorehouseRepository repository) { this.repository = repository; } public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext) { var region = bindingContext.ValueProvider.GetValue("region").AttemptedValue; var storehouse = bindingContext.ValueProvider.GetValue("storehouse").AttemptedValue; return repository.GetByKey(region, storehouse); } } If there was a single key, bindingContext.ModelName could be used... Probably, there is another way to supply all the actions with a Storehouse object, i.e. declaring it as a property of the controller and populating it in the Controller.Initialize.

  • Sometimes can rename, remove a folder; sometimes cannot

    - by Vy Clarks
    In my website project. I need to rename or remove some folder by code. Sometimes I can do all of that, but sometimes I cannot with error: Access to the path is denied Try to find to solution on Google. May be, there are two reason: The permisstion of that Folder Some subFolder or some file in that Folder that's being held open. Try to check: Right click on Folder- Properties-- Security: if this is the right way to check the permission, the Folder allowes every action (read, write....) There are no file, no subfolder of that Folder is opened. Why? I still dont understant why sometimes I can rename folder but sometimes I cannot. Help!! I need your opinions!!! UPDATE: take a look at my code above: I want to rename the a folder with the new name inputed in a Textbox txtFilenFolderName: protected void btnUpdate_Click(object sender, EventArgs e) { string[] values = EditValue; string oldpath = values[0];// = "D:\\C#Projects\\website\\Lecturer\\giangvien\\New folder" string oldName = values[2]; //= New Folder string newName = txtFilenFolderName.Text; //= New Folder1 string newPath = string.Empty; if (oldName != newName) { newPath = oldpath.Replace(oldName, newName); Directory.Move(oldpath, newPath); } else lblmessage2.Text = "New name must not be the same as the old "; } } Try to debug: oldpath = "D:\\C#Projects\\website\\Lecturer\\giangvien\\New folder" oldName = New Folder newName= New Folder1 newpath = "D:\\C#Projects\\website\\Lecturer\\giangvien\\New folder1" Everything seems right, but I when I click on buton Edit --- rename--- Update--- an error occur: Access to the path is denied D:\\C#Projects\\website\\Lecturer\\giangvien\\New folder Help!

  • Scrollbars in ScrollView not showing after custom child view changes size

    - by Ted Hopp
    I have a ScrollView containing a client that is a vertical LinearLayout. The client, in turn, contains custom views that change height dynamically as a background thread does some work. The problem I'm having is that the ScrollView's vertical scroll bar is not updating correctly in Android 1.5. The most common problem occurs when the initial total height of the client is less than the viewport and grows. Initially there is no scroll bar, and it does not show up when the client grows until I actually scroll the window with a touch gesture or other UI action. After that, the scroll bar shows up. However, the thumb does not update as the height continues to change from the background thread. If I scroll the view again through the UI, the thumb immediately corrects itself. My code for updating the height from the background thread is: post(mLayoutRequestor); postInvalidate(); (mLayoutRequestor is a Runnable that just calls requestLayout().) This is done after I've recorded the new height in a variable mHeight. My onMeasure() method calls setMeasuredDimension with a height computed like this: private int measureHeight(int measureSpec) { int result; int specMode = MeasureSpec.getMode(measureSpec); int specSize = MeasureSpec.getSize(measureSpec); if (specMode == MeasureSpec.EXACTLY) { result = specSize; } else { result = mHeight; if (specMode == MeasureSpec.AT_MOST && result > specSize) result = specSize; } return result; } Am I supposed to be calling something else besides requestLayout() to get the scroll bar to update correctly?

  • Submit form with POST data in Android app

    - by datguywhowanders
    I've been searching the web for a way to do this for about a week now, and I just can't seem to figure it out. I'm trying to implement an app that my college can use to allow users to log in to various services on the campus with ease. The way it works currently is they go to an online portal, select which service they want, fill in their user name and pwd, and click login. The form data is sent via post (it includes several hidden values as well as just the user name and pwd) to the corresponding login script which then signs them in and loads the service. I've been trying to come at the problem in two ways. I first tried a WebView, but it doesn't seem to want to support all of the html that normally makes this form work. I get all of the elements I need, fields for user and pwd as well as a login button, but clicking the button doesn't do anything. I wondered if I needed to add an onclick handler for it, but I can't see how as the button is implemented in the html of the webview not using a separate android element. The other possibility was using the xml widgets to create the form in a nice relative layout, which seems to load faster and looks better on the android screen. I used EditText fields for the input, a spinner widget for the service select, and the button widget for the login. I know how to make the onclick and item select handlers for the button and spinner, respectively, but I can't figure out how to send that data via POST in an intent that would then launch a browser. I can do an intent with the action url, but can't get the POST data to feed into it. Anyone have any suggestions?

  • Spree customize/extend user roles and permissions

    - by swapnil
    I am trying to specify some custom roles in Spree for example role 'client' and extend the permissions to access the admin section for this role. This user will be able to access only those Product created by that user. Concept is letting a user with role 'client' manage only products and other certain Models. To start with I added CanCan plugin and defined a RoleAbility Class in role_ability.rb Just following this post : Spree Custom Roles Permissions class RoleAbility include CanCan::Ability def initialize(user) user ||= User.new if user.has_role? 'admin' can :manage, :all elsif user.has_role? 'client_admin' can :read, Product can :admin, Product end end end Added this to an initializer : config/initializers/spree.rb Ability.register_ability(RetailerAbility) Also extended admin_products_controller_decorator.rb :app/controllersadmin_products_controller_decorator.rb Admin::ProductsController.class_eval do def authorize_admin authorize! :admin, Product authorize! params[:action].to_sym, Product end end But I am getting flash message 'Authorisation Failure' Trying to find some luck, I referred following links A github gist for Customizing Spree Roles : https://gist.github.com/1277326 Here's a similar issue what I am facing : http://groups.google.com/group/spree-user/browse_thread/thread/1e819e10410d03c5/23b269e09c7ed47e All efforts in vain... Any pointers of what is going on here highly appreciated ? Thanks in advance.

  • Rails uploaded file blank

    Hi chaps, I'm trying to upload a file to the server using a HTTP multipart form in rails, and for some reason it's turning up blank at the other end. I can see it being received in the rails log thusly: Processing Admin::HeadlinesController#update (for 127.0.0.1 at 2010-03-08 12:26:13) [PUT] Parameters: {"commit"=>"Save changes", "action"=>"update", "_method"=>"put", "authenticity_token"=>"mK70XRk5gOPUwXOcNboT/4K8PD9RBM7GqCOlEUKZwcA=", "headline"=>{"position"=>"1", "location"=>"primary", "attachment_id"=>"13", "headline_content"=>"questionnaires", "article_id"=>"3", "image"=>#<File:/tmp/RackMultipart20100308-63211-1vym9nj-0>}, "id"=>"140", "controller"=>"admin/headlines"} But if I have a look in /tmp/RackMultipart20100308-63211-1vym9nj-0 the file is blank.

  • UIButton only responds in a small area

    - by Tom Irving
    I'm trying to add a UIButton to a UIView, but am having some trouble with getting it to respond to touches. I have a method which returns UIButtons after I provide it with a tag: - (UIButton*)niceSizeButtonWithTag:(int)tag { UIButton * aButton = [UIButton buttonWithType:UIButtonTypeCustom]; [aButton setTag:tag]; [aButton addTarget:self action:@selector(buttonWasTapped:) forControlEvents:UIControlEventTouchUpInside]; CGRect newFrame = aButton.frame; newFrame.size.width = 44; newFrame.size.height = 44; [aButton setFrame:newFrame]; return aButton; } As you can see I'm creating a new button and increasing the size. I use this in the following way: UIButton * anotherButton = [self niceSizeButtonWithTag:1]; [anotherButton setImage:[UIImage imageNamed:@"image" withExtension:@"png"] forState:UIControlStateNormal]; [anotherButton setCenter:CGPointMake(middleOfView)]; [aView addSubview:anotherButton]; I create a lot of buttons like this, hence the reason for the method. The buttons are always created and added to the subview perfectly. I can see the image and they're in the correct position. The problem is that they only respond to touches in a tiny strip. In this attached image, The yellow shows the whole frame of the button, The red shows the area that will respond to touches. The grey shows a section of the view the button is added to. If anyone could shed some light on why this is happening, it would be really useful.

  • Same jQuery code returns two different results – Submit Button Text

  • Jquery click bindings are not working correctly when binding multiple copies

    - by KallDrexx
    I seem to have an issue when creating copies of a template and tying the .click() method to them properly. Take the following javascript for example: var list; // Loop through all of the objects var topics = data.objects; for (x = 0; x < objects.length; x++) { // Clone the object list item template var item = $("#object_item_list_template").clone(); // Setup the click action and inner text for the link tag in the template var objectVal = objects[x].Value; item.find('a').click(function () { ShowObject(objectVal.valueOf(), 'T'); }).html(objects[x].Text); // add the html to the list if (list == undefined) list = item; else list.append(item.contents()); } // Prepend the topics to the topic list $("#object_list").empty().append(list.contents()); The problem I am seeing with this is that no matter which item the user clicks on in the #object_list, ShowObject() is called with the last value of objectVal. So for example, if the 3rd item's <a> is clicked, ShowObject(5,'T'); is called even though objects[2].Value is successfully being seen as 2. How can I get this to work? The main purpose of this code is to take a variable number of items gotten from a JSON AJAX request, make copies of the item template, and insert those copies into the correct spot on the html page. I decided to do it this way so that I can keep all my HTML in one spot for when I need to change the layout or design of the page, and not have to hunt for the html code in the javascript.

  • Any danger in calling flash messages html_safe?

    - by PreciousBodilyFluids
    I want a flash message that looks something like: "That confirmation link is invalid or expired. Click here to have a new one generated." Where "click here" is of course a link to another action in the app where a new confirmation link can be generated. Two drawbacks: One, since link_to isn't defined in the controller where the flash message is being set, I have to put the link html in myself. No big deal, but kind of messy. Number two: In order for the link to actually display properly on the page I have to html_safe the flash display function in the view, so now it looks like (using Haml): - flash.each do |name, message| = content_tag :div, message.html_safe This gives me pause. Everything else I html_safe has been HTML I've written myself in helpers and whatnot, but the contents of the flash hash are stored in a cookie client-side, and could conceivably be changed. I've thought through it, and I don't see how this could result in an XSS attack, but XSS isn't something I have a great understanding of anyway. So, two questions: 1. Is there any danger in always html_safe-ing all flash contents like this? 2. The fact that this solution is so messy (breaking MVC by using HTML in the controller, always html_safe-ing all flash contents) make me think I'm going about this wrong. Is there a more elegant, Rails-ish way to do this? I'm using Rails 3.0.0.beta3.

  • IIS6, ASP.NET MVC 1 and random slowdowns

    - by Mr Snuffle
    I've recently deployed a MVC application to an IIS6 web server. One strange behaviour I've been having is the load times will randomly blow up to 30sec+ and then return to normal. Our tests have shown this occurring on multiple connections at the same time. Once the wait has passed, the site become responsive again. It's completely random when this will occur, but will probably happen about once every 15 minutes or so. My first thought was the application was being restarted by the web server for some reason, but I determined this wasn't the case because the process recycling is set very infrequently, and I placed some logging in the application startup. It's also nothing to do with the database connection. This slowdown happens simply by moving between static pages too. I've watched the database with a SQL profiler, and nothing is hitting it when these slowdowns occur. Finally, I've placed entry and exit logging on my controller actions, the slowdown always happens outside of the controller. The entry and exit time for a controller action is always appropriately fast. Does anyone have any ideas of what could be causing this? I've tried running it locally on IIS7 and I haven't had the issue. I can only think it's something to do with our hosting provider.

  • Vertically Aligning Divs

    - by Crays
    Hi, i'm trying to make a small username and password input box. I would like to ask how do you vertically align a div? What i have is a <div id="Login" class="BlackStrip floatright"> <div id="Username" class="floatleft">Username<br>Password</div> <div id="Form" class="floatleft"> <form action="" method="post"> <input type="text" border="0"><br> <input type="password" border="0"> </form> </div> </div> and how can i make the div with id Username and Form to vertically align itself to the center? I tried putting vertical-align: middle; in css for the div with id Login. But doesn't seem to work. Any help would be appreciated. Thanks.
