  • Update successful notice with pure css and a close button

    - by Crays
    Hi guys, i've seen websites that allow you to say update your profile and when the stuff is done, they'll stay in the same page or redirect you to another and with a fancy notice that says "Update successful. click here to close" with a lowered opacity black background and a box in the middle with the text within. I've got most of the stuff, the lowred opacity black background, the middle box with the text and even the click here to close function. But how i did the "Click here to close" function is by using a link. Let's say after updating the profile, my script redirect me to index.php?update=successful then i use $update = $_GET['update']; if ($update == "successful") { echo '<div id="BlackScreen"><p id="MiddleBox">You\'ve successfully update your status!<br><span class="close"><a class="menu" href="index.php">Click to close. </a></span></div></div>'; } so that the lowered opacity background div will be gone, but is there another way to do this? Any tips please?

  • How to use Enquire.Js?

    - by big_smile
    Enquire.js is a Javascipt that re-creates CSS media queries for Javascripts. This means you can wrap your Javascripts in Media Queries. (Just like you would wrap CSS in Media Queries). I'm not quite sure how to use it. This tutorial says this: enquire.register("max-width: 960px", function() { // put your code here }); However, when I follow that, my code stops working. Here is an example of some Jquery Tabs without Enquire.JS. It works fine. Here are the same tabs, but with Enquire.JS added. Now it stops working. I've experimented with different variations of the code, but none of them work. What am I doing wrong? I think you might have place the Jquery Tab code in a separate file and then link to that file from within Enquire.Js, but I'm not sure how you would do that. (Although it would be handy to know as I'd imagine it would let you keep your scripts be more reusable). PS. This is not a criticism of Enquire.Js. I know that the problem lies squarely with my lack of proficiency in Javascript! I did spend a couple of hours searching for a solution, but couldn't find anything. Thanks for any help!

  • manyToOne is creating new products

    - by user788721
    I am trying to implement Sylius Cart Bundle, but every time I add a product to the cart, a new product is created. This is probably link to my line: cascade: ["persist", "remove"] In my YAML File: Pharmacie\FrontBundle\Entity\CartItem: type: entity table: app_cart_item manyToOne: produit: targetEntity: Pharmacie\FrontBundle\Entity\Product cascade: ["persist", "remove"] joinColumn: name: product_id referencedColumnName: id But if take it off, I get an error: A new entity was found through the relationship 'Pharmacie\FrontBundle\Entity\CartItem#produit' that was not configured to cascade persist operations for entity: 3test2. To solve this issue: Either explicitly call EntityManager#persist() on this unknown entity or configure cascade persist this association in the mapping for example @ManyToOne(..,cascade={"persist"}) According to the doctrine doc, this error occurs when you set a new object. But I am only getting an existing object By ID: $product = $this->getProductRepository()->find($productId); $item->setProduit($product); //this generates the error $item->setUnitPrice(5); //this works fine I don't understand why it's save as a new object. If I use merge instead of persist, I get the same error: A new entity was found through the relationship...

  • jquery for ruby on rails

    - by Cezar
    Hello, I am tying to use this code http://gist.github.com/110410 to dump Prototype in favor of jQuery but I do have a problem. This is my HTML (a link_to generated link): <a onclick="var f = document.createElement('form'); f.style.display = 'none'; this.parentNode.appendChild(f); f.method = 'POST'; f.action = this.href;var s = document.createElement('input'); s.setAttribute('type', 'hidden'); s.setAttribute('name', 'authenticity_token'); s.setAttribute('value', 'Mi6RcR6YDyvg2uNwGrpbeIJutSHa2fYboU37wSDE7AU='); f.appendChild(s);f.submit();return false;" class="post add_to_cart " href="/line_items?product_id=547">Add to cart</a> Issue: Everything works as it should except that the page does a reload. I suspect that the submit gets thru which causes a page reload. Is there an elegant way to prevent that ? return false; doesn't seem to cut it in this case.

  • HTML relative links on various domains

    - by Adam Kiss
    I have quickie: When you code/develop themes, how do you link to various files in your html/css code? Example: We at our firm use mostly <base target="http://whatever"> in our main template and then just <img src="./images/file.png"> in our html, "/category/page" as links and something alike in our css. However, when testing on different machines, we use ip address rather than localhost on main dev station of coder, so all base links don't work (because localhost goes to viewing machine, not coder's, in our network). Same thing happens when updating pages - on dev server, we have to edit base target, so browsing site won't take us to live site - this part is actually rather simple PHP (if ... echo else echo something else), but it still not solve problem of more coding-testing problems. So, my question is, how do YOU solve it? How do you use relative links, which basically don't care for what domain is the page on and don't care for url rewrite? (because ../images/ is different for / and different for /something/somethingElse/page)?

  • How to convert Big Endian and how to flip the highest bit?

    - by Robert Frank
    I am using a TStream to read binary data (thanks to this post: http://stackoverflow.com/questions/2878180/how-to-use-a-tfilestream-to-read-2d-matrices-into-dynamic-array). My next problem is that the data is Big Endian. From my reading, the Swap() method is seemingly deprecated. How would I swap the types below? 16-bit two's complement binary integer 32-bit two's complement binary integer 64-bit two's complement binary integer IEEE single precision floating-point - Are IEEE affected by Big Endian? And, finally, since the data is unsigned, the creators of this dataset have stored the unsigned values as signed integers (excluding the IEEE). They instruct that one need only add an offset (2^15, 2^31, and 2^63) to recover the unsigned data. But, they note that flipping the most significant bit is the fastest way to do that. How does one efficiently flip the most significant bit of a 16, 32, or 64-bit integer? So, if the data on disk (16-bit) is "85 FB" - the desired result after reading the data and swapping and bit flipping would be 1531. Is there a way to accomplish the swapping and bit flipping with generics so it fits into the generic answer at the link above? Yes, kids, THIS is how scientific astronomical data is stored by NASA, ESO, and all professional astronomers. This FITS standard is considered by some to be one of the most successful standards ever created in its proliferation and flexibility!

  • How can I solve the Log Pile wooden puzzle with a computer program?

    - by craig1410
    Can anyone suggest how to solve the Log Pile wooden puzzle using a computer program? See here to visualise the puzzle: http://www.puzzlethis.co.uk/products/madcow/the_log_pile.htm The picture only shows some of the pieces. The full set of 10 pieces are configured as follows with 1 representing a peg, -1 representing a hole and 0 representing neither a peg nor a hole. -1,1,0,-1,0 1,0,1,0,0 1,-1,1,0,0 -1,-1,0,0,-1 -1,1,0,1,0 0,1,0,0,1 1,0,-1,0,-1 0,-1,0,1,0 0,0,-1,1,-1 1,0,-1,0,0 The pieces can be interlocked in two layers of 5 pieces each with the top layer at 90 degrees to the bottom layer as shown in the above link. I have already created a solution to this problem myself using Java but I feel that it was a clumsy solution and I am interested to see some more sophisticated solutions. Feel free to either suggest a general approach or to provide a working program in the language of your choice. My approach was to use the numeric notation above to create an array of "Logs". I then used a combination/permutation generator to try all possible arrangements of the Logs until a solution was found where all the intersections equated to zero (ie. Peg to Hole, Hole to Peg or Blank to Blank). I used some speed-ups to detect the first failed intersection for a given permutation and move on to the next permutation. I hope you find this as interesting as I have. Thanks, Craig.

    - by mary4pfc
    Hi! I'm building an application whose menus depend on user roles. Once user is logged in and, therefore, her roles are known, I want to create the Hyperlinks related to the user and add them to the menu. I'm using MVP. Here's my code for the presenter: public class AdminMenuAreaPresenter extends WidgetPresenter<AdminMenuAreaPresenter.Display> { public interface Display extends WidgetDisplay{ public void addLink(String link); } private DispatchAsync dispatcher; private SessionManager sessionManager; @Inject public AdminMenuAreaPresenter(AdminMenuAreaPresenter.Display display, EventBus bus, DispatchAsync dispatcher, SessionManager sessionManager){ super(display, bus); this.dispatcher = dispatcher; this.sessionManager = sessionManager; this.bind(); } @Override protected void onBind() { super.onBind(); registerHandler(eventBus.addHandler(LoginEvent.TYPE, new LoginEventHandler() { @Override public void onLogin(LoginEvent event) { display.addLink("register user"); } })); } @Override protected void onUnbind() { // TODO Auto-generated method stub } @Override protected void onRevealDisplay() { // TODO Auto-generated method stub } } And here's the View: public class AdminMenuAreaView extends Composite implements AdminMenuAreaPresenter.Display{ private VerticalPanel vPanel; private Hyperlink registerUserLink; public AdminMenuAreaView(){ vPanel = new VerticalPanel(); initWidget(vPanel); } @Override public Widget asWidget() { return this; } public void addLink(String s){ registerUserLink = new Hyperlink(s, "this is new target"); this.vPanel.add(registerUserLink); registerUserLink.setVisible(true); } public HasClickHandlers getRegisterUserLink(){ return registerUserLink; } What am I doing wrong?

  • Creating a process in ASP.NET MVC controller

    - by GRKamath
    I have a requirement to run an application through my MVC controller. To get the installation path I used following link (I used answer provided by Fredrik Mörk). It worked and I could able to run the exe through a process. The problem occurred when I deployed this solution on IIS where it did not create the process as it was creating in local dev environment. Can anybody tell me how to create a windows process through a solution which is hosted on IIS ? private string GetPathForExe(string fileName) { private const string keyBase = @"SOFTWARE\Wow6432Node\MyApplication"; RegistryKey localMachine = Registry.LocalMachine; RegistryKey fileKey = localMachine.OpenSubKey(string.Format(@"{0}\{1}", keyBase, fileName)); object result = null; if (fileKey != null) { result = fileKey.GetValue("InstallPath"); } fileKey.Close(); return (string)result; } public void StartMyApplication() { Process[] pname = Process.GetProcessesByName("MyApplication"); if (pname.Length == 0) { string appDirectory = GetPathForExe("MyApplication"); Directory.SetCurrentDirectory(appDirectory); ProcessStartInfo procStartInfo = new ProcessStartInfo("MyApplication.exe"); procStartInfo.WindowStyle = ProcessWindowStyle.Hidden; Process proc = new Process(); proc.StartInfo = procStartInfo; proc.Start(); } }

  • Excel VBA creating a new column with formula

    - by Amatya
    I have an excel file with a column which has date data. I want the user to input a date of their choosing and then I want to create a new column that lists the difference in days between the two dates. The Macro that I have is working but I have a few questions and I would like to make it better. Link to MWE small data file is here. The user input date was 9/30/2013, which I stored in H20 Macro: Sub Date_play() Dim x As Date Dim x2 As Date Dim y As Variant x = InputBox(Prompt:="Please enter the Folder Report Date. The following formats are acceptable: 4 1 2013 or April 1 2013 or 4/1/2013") x2 = Range("E2") y = DateDiff("D", x2, x) MsgBox y 'Used DateDiff above and it works but I don't know how to use it to fill a column or indeed a cell. Range("H20").FormulaR1C1 = x Range("H1").FormulaR1C1 = "Diff" Range("H2").Formula = "=DATEDIF(E2,$H$20,""D"")" Range("H2").AutoFill Destination:=Range("H2:H17") Range("H2:H17").Select End Sub Now, could I have done this without storing the user input date in a particular cell? I would've preferred to use the variable "x" in the formula but it wasn't working for me. I had to store the user input in H20 and then use $H$20. What's the difference between the function Datedif and the procedure DateDiff? I am able to use the procedure DateDiff in my macro but I don't know how to use it to fill out my column. Is one method better than the other? Is there a better way to add columns to the existing sheet, where the columns include some calculations involving existing data on the sheet and some user inputs? There are tons of more complicated calculations I want to do next. Thanks

  • Expandable paragraphs with HTML and CSS

    - by user3704175
    I was wondering if anyone here would be as so kind as to help me out a bit. I am looking to make expandable paragraphs for my client's website. They would like to keep all of the content from their site, which is pretty massive, and they want a total overhaul of the design. They mainly wan tot keep it for SEO purposes. Anyhow, I thought it would be helpful for the both of use if there is some way to use expandable paragraphs, you know, with a "read more..." link after a certain line of text. I know that there are some JQuery and Java solutions for this, but we really would like to stay away from those options, if at all possible. When would like HTML and CSS, if we can. Here is kind of an example: HEADING HERE Paragraph with a bunch of text. I would like this to appear in a pre-determined line. For example, maybe the start of the paragraph goes on for, let's say, three lines and then we have the [read more...] When the visitor clicks "read more", we would like the rest of the content to just expand to reveal the article in its entirety. I would like for the content to already be on the page, so it just expands. I don't want it to be called in from another file or anything, if that makes sense. Thank you in advance for any and all help. It will be greatly appreciated! Testudo

  • Html.RadioButton group defaulting to 0

    - by awrigley
    Hi A default value of 0 is creeping into a Surveys app I am developing, for no reason that I can see. The problem is as follows: I have a group of Html.RadioButtons that represent the possible values a user can choose to answer a survey question (1 == Not at all, 2 == A little, 3 == A lot). I have used a tinyint datatype, that does not allow null, to store the answer to each question. The view code looks like this: <ol class="SurveyQuestions"> <% foreach (SurveyQuestion question in Model.Questions) { string col = question.QuestionColumn; %> <li><%=question.QuestionText%> <ul style="float:right;" class="MultiChoice"> <li><%= Html.RadioButton(col, "1")%></li> <li><%= Html.RadioButton(col, "2")%></li> <li><%= Html.RadioButton(col, "3")%></li> </ul> <%= Html.ValidationMessage(col, "*") %> </li> <% } %> </ol> [Note on the above code:] Each survey has about 70 questions, so I have put the questions text in one table, and store the results in a different table. I have put the Questions into my form view model (hence Model.Questions); the questions table has a field called QuestionColumn that allows me to link up the answer table column to the question, as shown above (<%= Html.RadioButton(col, "1")%, etc) [/Note] However, when the user DOESN'T answer the question, the value 0 is getting inserted into the database column. As a result, I don't get what I expect, ie, a validation error. In no place have I stipulated a default value of 0 for the fields in the answers table. So what is happening? Any ideas?

  • Execute SSH commands on Cisco router. Codeigniter SSH library

    I have a little problem. I'm using Codeigniter with SSH library written by Shuky (https://bitbucket.org/quicktips/codeigniter-ssh2-library/src/a444968345ba/SSH.php -- You can see the code by following this link). Everything related with SSH works fine with other devices, but when I try to use this library and execute commands on Cisco devices, nothing happens (commands are not executed). I know that the connection is successful, but I can't execute any commands.

  • How is an AppDelegate instanciated?

    - by pwny
    I have an iOS application for which I want to create a ViewController programmatically. I started an empty XCode project and modified the main method so it looks like this int main(int argc, char *argv[]) { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; int retVal = UIApplicationMain(argc, argv, nil, @"MyAppDelegate_iPad"); [pool release]; return retVal; } The app is a Universal Application, MyAppDelegate_iPad is a subclass of MyAppDelegate, which is a subclass of NSObject <UIApplicationDelegate>. My problem is that the applicationDidFinishLoading method I've overridden in MyAppDelegate_iPad is never called (break point on the first line never hits). The method looks like this -(void) applicationDidFinishLaunching:(UIApplication *)application { window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; if(!window) { [self release]; return; } window.backgroundColor = [UIColor whiteColor]; rootController = [[MyViewController alloc] init]; [window addSubview:rootController.view]; [window makeKeyAndVisible]; [window layoutSubviews]; } I removed the line to link to a nib file from my plist file (I used to get the default "My Universal app on iPad" white screen) and now all that is displayed is a black screen. applicationDidFinishLoading is still not being called. Am I doing something wrong? How should I properly create my AppDelegate instance?

  • iPhone or Android apps that use SMS based authentication?

    - by JSW
    What are some iPhone or Android applications that use SMS as their primary means of user authentication? I'm interested to see such apps in action. SMS-auth seems like a natural approach that is well-situated to mobile contexts. The basic workflow is: to sign up, a user provides a phone number; the app calls a backend webservice which generates a signed URL and sends it to the phone number via an SMS gateway; the user receives the SMS, clicks the link, and is thus verified and logged in. This results in a very strong user identity that is difficult to spoof yet fairly easy. It can be paired with a username or additional account attributes as needed for the product requirements. Despite the advantages, this does not seem to be in much use - hence my question. My initial assumption is that this is because products and users are wary of asking for / providing phone numbers, which users consider sensitive information. That said, I hope this becomes an increasingly more commonplace approach.

  • What goes into main function?

    - by Woltan
    I am looking for a best practice tip of what goes into the main function of a program using c++. Currently I think two approaches are possible. (Although the "margins" of those approaches can be arbitrarily close to each other) 1: Write a "Master"-class that receives the parameters passed to the main function and handle the complete program in that "Master"-class (Of course you also make use of other classes). Therefore the main function would be reduced to a minimum of lines. #include "MasterClass.h" int main(int args, char* argv[]) { MasterClass MC(args, argv); } 2: Write the "complete" program in the main function making use of user defined objects of course! However there are also global functions involved and the main function can get somewhat large. I am looking for some general guidelines of how to write the main function of a program in c++. I came across this issue by trying to write some unit test for the first approach, which is a little difficult since most of the methods are private. Thx in advance for any help, suggestion, link, ...

  • password-check directive in angularjs

The issue is that it works one way (i.e. when I type a password in the password-verify field). However, when the original password field is updated, the password-verify doesn't become valid. Any idea how I could have a "two way binding verify?"

  • Need help with threads in a client/server

    - by nunos
    For college, I am developing a local relay chat. I have to program a chat server and client that will only work on sending messages on different terminal windows on the same computer with threads and fifos. The fifos part I am having no trouble, the threads part is the one that is giving me some headaches. The server has one thread for receiving commands from a fifo (used by all clients) and another thread for each client that is connected. For each client that is connected I need to know a certain information. Firstly, I was using global variables, which worked as longs as there was only one client connected, which is much of a chat, to chat alone. So, ideally I would have some data like: -nickname -name -email -etc... per client that is connected. However, I don't know how to do that. I could create a client_data[MAX_NUMBER_OF_THREADS] where client_data was a struct with everything I needed to have access to, but this would require to, in every communication between server and client to ask for the id of the client in the array client_data and that does not seem very pratical I could also instantiate a client_data immediately after creating the thread but it would only be available in that block, and that is not very pratical either. As you can see I am in need of a little guidance here. Any comment, piece of code or link to any relevant information is greatly appreciated. Thanks.

  • Deploying DotNetNuke and separate ASP.NET Application together - Possible Issues?

    - by TheTXI
    I am making this in a proactive attempt to head off any potential problems which could arise from this. The situation is that we are developing an ASP.NET application for a client which will handle the online ordering from their customers. This application is going to be using the same database that their current WinForms application uses (no real issue here). At the same time we are developing a new front-end website for them using DotNetNuke. The DotNetNuke app will simply be linking to the ASP.NET application for the customers to submit their orders (no need for them to communicate back and forth, etc.) The plan is to host both applications on the same box at the client location. What I am looking for are potential problems or setup tips which would prevent possible conflict between the two apps (web.config conflicts, etc.) Is there a problem with having both hosted on the same location, how should IIS be set up, etc.? If there are any external resources also available which could address this, please feel free to link them as well.

  • How should I handle expected errors? eg. "username already exists"

    - by Pheter
    I am struggling to understand how I should design the error handling parts of my code. I recently asked a similar question about how I should go about returning server error codes to the user, eg. 404 errors. I learnt that I should handle the error from within the current part of the application; seem's simple enough. However, what should I do when I can't handle the error from the current link in the chain? For example, I may have a class that is used to manage authentication. One of it's methods could be createUser($username, $password). Within that function, I need to determine if the username already exists. If this is true, how should I alert the calling code about this? Returning null instead of a user object is one way. But how do I then know what caused the error? How should I handle errors in such a way that calling code can easily find out what caused the error? Is there a design pattern commonly used for this kind of situation?
