  • Submit form with JS

    - by Thomas
    Im working with a shopping cart plugin and that uses a basic form on the product page to submit values like price, product name, etc.. The problem is that the plugin uses a standard submit button to send the values and I would like to replace said button with a prettier custom jquery rollover. In order to make this happen I used some JS and tossed a link around my custom submit button: <a href="#" onclick="document.forms[0].submit()" value="Add to Cart" onsubmit="return ReadForm(this, true);"> <img class="fade" src="style/img/add_btn.jpg" style="background: url(style/img/add_ro.png);" alt=""/> </a> The form submits and the user is redirected to the homepage but the data in the form doesn't seem to get submitted and the product never gets added to the 'cart' page. I suspect that the form is getting submitted but I am failing to fire some additional JS function that submits the data. The plugin adds some JS to the top of the page: <!-- // function ReadForm (obj1, tst) { // Read the user form var i,j,pos; val_total="";val_combo=""; for (i=0; i<obj1.length; i++) { // run entire form obj = obj1.elements[i]; // a form element if (obj.type == "select-one") { // just selects if (obj.name == "quantity" || obj.name == "amount") continue; pos = obj.selectedIndex; // which option selected val = obj.options[pos].value; // selected value val_combo = val_combo + "(" + val + ")"; } } // Now summarize everything we have processed above val_total = obj1.product_tmp.value + val_combo; obj1.product.value = val_total; } //--> If you want to check out the the site in question, take a look here and click 'add to cart button': http://hardtopdepot.com/?p=34 You can see the cart at the top: http://hardtopdepot.com/?page_id=50 Any help would be super appreciated- thanks!

  • Parse JSON into a ListView friendly output

    - by Thomas McDonald
    So I have this JSON, which then my activity retrieves to a string: {"popular": {"authors_last_month": [ { "url":"http://activeden.net/user/OXYLUS", "item":"OXYLUS", "sales":"1148", "image":"http://s3.envato.com/files/15599.jpg" }, { "url":"http://activeden.net/user/digitalscience", "item":"digitalscience", "sales":"681", "image":"http://s3.envato.com/files/232005.jpg" } { ... } ], "items_last_week": [ { "cost":"4.00", "thumbnail":"http://s3.envato.com/files/227943.jpg", "url":"http://activeden.net/item/christmas-decoration-balls/75682", "sales":"43", "item":"Christmas Decoration Balls", "rating":"3", "id":"75682" }, { "cost":"30.00", "thumbnail":"http://s3.envato.com/files/226221.jpg", "url":"http://activeden.net/item/xml-flip-book-as3/63869", "sales":"27", "item":"XML Flip Book / AS3", "rating":"5", "id":"63869" }, { ... }], "items_last_three_months": [ { "cost":"5.00", "thumbnail":"http://s3.envato.com/files/195638.jpg", "url":"http://activeden.net/item/image-logo-shiner-effect/55085", "sales":"641", "item":"image logo shiner effect", "rating":"5", "id":"55085" }, { "cost":"15.00", "thumbnail":"http://s3.envato.com/files/180749.png", "url":"http://activeden.net/item/banner-rotator-with-auto-delay-time/22243", "sales":"533", "item":"BANNER ROTATOR with Auto Delay Time", "rating":"5", "id":"22243"}, { ... }] } } It can be accessed here as well, although it because it's quite a long string, I've trimmed the above down to display what is needed. Basically, I want to be able to access the items from "items_last_week" and create a list of them - originally my plan was to have the 'thumbnail' on the left with the 'item' next to it, but from playing around with the SDK today it appears too difficult or impossible to achieve this, so I would be more than happy with just having the 'item' data from 'items_last_week' in the list. Coming from php I'm struggling to use any of the JSON libraries which are available to Java, as it appears to be much more than a line of code which I will need to deserialize (I think that's the right word) the JSON, and they all appear to require some form of additional class, apart from the JSONArray/JSONObject script I have which doesn't like the fact that items_last_week is nested (again, I think that's the JSON terminology) and takes an awful long time to run on the Android emulator. So, in effect, I need a (preferably simple) way to pass the items_last_week data to a ListView. I understand I will need a custom adapter which I can probably get my head around but I cannot understand, no matter how much of the day I've just spent trying to figure it out, how to access certain parts of a JSON string..

  • New Application Process from Bash Shell

    - by Thomas Uster
    I'm relearning UNIX commands to use git on windows using MINGW32. When I launch a program, for example "$ notepad hello.txt" I can't use the shell again until I close the notepad file or CTRL-C in the shell. How do I essentially fork a new process so I can use both programs?

  • Creating base class for Entities in Entity Framework

    - by Thomas
    I would like to create a base class that is somewhat generic for all of my entities. The class would have methods like Save(), Delete(), GetByID() and some other basic functionality and properties. I have more experience with Linq to SQL and was hoping to get some good examples for something similar in the EF. Thank you.

  • Unselecting RadioButtons in Java Swing

    - by Thomas
    When displaying a group of JRadioButtons, initially none of them is selected (unless you programmatically enforce that). I would like to be able to put buttons back into that state even after the user already selected one, i.e., none of the buttons should be selected. However, using the usual suspects doesn't deliver the required effect: calling 'setSelected(false)' on each button doesn't work. Interestingly, it does work when the buttons are not put into a ButtonGroup - unfortunately, the latter is required for JRadioButtons to be mutually exclusive. Also, using the setSelected(ButtonModel, boolean) - method of javax.swing.ButtonGroup doesn't do what I want. I've put together a small program to demonstrate the effect: two radio buttons and a JButton. Clicking the JButton should unselect the radio buttons so that the window looks exactly as it does when it first pops up. import java.awt.Container; import java.awt.GridLayout; import java.awt.event.*; import javax.swing.*; /** * This class creates two radio buttons and a JButton. Initially, none * of the radio buttons is selected. Clicking on the JButton should * always return the radio buttons into that initial state, i.e., * should disable both radio buttons. */ public class RadioTest implements ActionListener { /* create two radio buttons and a group */ private JRadioButton button1 = new JRadioButton("button1"); private JRadioButton button2 = new JRadioButton("button2"); private ButtonGroup group = new ButtonGroup(); /* clicking this button should unselect both button1 and button2 */ private JButton unselectRadio = new JButton("Unselect radio buttons."); /* In the constructor, set up the group and event listening */ public RadioTest() { /* put the radio buttons in a group so they become mutually * exclusive -- without this, unselecting actually works! */ group.add(button1); group.add(button2); /* listen to clicks on 'unselectRadio' button */ unselectRadio.addActionListener(this); } /* called when 'unselectRadio' is clicked */ public void actionPerformed(ActionEvent e) { /* variant1: disable both buttons directly. * ...doesn't work */ button1.setSelected(false); button2.setSelected(false); /* variant2: disable the selection via the button group. * ...doesn't work either */ group.setSelected(group.getSelection(), false); } /* Test: create a JFrame which displays the two radio buttons and * the unselect-button */ public static void main(String[] args) { JFrame frame = new JFrame(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); RadioTest test = new RadioTest(); Container contentPane = frame.getContentPane(); contentPane.setLayout(new GridLayout(3,1)); contentPane.add(test.button1); contentPane.add(test.button2); contentPane.add(test.unselectRadio); frame.setSize(400, 400); frame.setVisible(true); } } Any ideas anyone? Thanks!

  • PHP in Wordpress Posts - Is this okay?

    - by Thomas
    I've been working with some long lists of information and I've come up with a good way to post it in various formats on my wordpress blog posts. I installed the exec-PHP plugin, which allows you to run php in posts. I then created a new table (NEWTABLE) in my wordpress database and filled that table with names, scores, and other stuff. I was then able to use some pretty simple code to display the information in a wordpress post. Below is an example, but you could really do whatever you wanted. My question is - is there a problem with doing this? with security? or memory? I could just type out all the information in each post, but this is really much nicer. Any thoughts are appreciated. <?php $theResult = mysql_query("SELECT * FROM NEWTABLE WHERE Score < 100 ORDER BY LastName"); while($row = mysql_fetch_array($theResult)) { echo $row['FirstName']; echo " " . $row['LastName']; echo " " . $row['Score']; echo "<br />"; } ?>

  • CSMA/CD once channel captured, can only one or multiple frames be sent before other stations try tra

    - by Bryce Thomas
    Hi there, I have a question regarding CSMA/CD in the IEEE 802.3 LAN standard. I'm trying to understand the behavior of CSMA/CD after a station has captured the channel. Say station A has captured the channel and has an infinite supply of frames it is sending. Also assume that station B has something it wants to send. Now, if I understand correctly, station B senses the line and sees that station A has captured the channel/is transmitting. My question is, does station B see the channel as being captured for the duration of ALL of the frames that station A sends (an infinite period of time), or does station B only consider the channel captured for the first frame it sees A send, after which B goes ahead and transmits its own frame (which will collide with one of the remaining frames still coming from A)?

  • Programmatically creating a clickable area on an image.

    - by Thomas Stock
    Hi, I'm trying to create "imagemaps" on an image in wpf using codebehind. See the following XML: <Button Type="Area"> <Point X="100" Y="100"></Point> <Point X="100" Y="200"></Point> <Point X="200" Y="200"></Point> <Point X="200" Y="100"></Point> <Point X="150" Y="150"></Point> </Button> I'm trying to translate this to a button on a certain image in my WPF app. I've already did a part of this, but I'm stuck at setting the Polygon as the button's "template": private Button GetAreaButton(XElement buttonNode) { // get points PointCollection buttonPointCollection = new PointCollection(); foreach (var pointNode in buttonNode.Elements("Point")) { buttonPointCollection.Add(new Point((int)pointNode.Attribute("X"), (int)pointNode.Attribute("Y"))); } // create polygon Polygon myPolygon = new Polygon(); myPolygon.Points = buttonPointCollection; myPolygon.Stroke = Brushes.Yellow; myPolygon.StrokeThickness = 2; // create button based on polygon Button button = new Button(); ????? } I'm also unsure on how to add/remove this button to/from my image, but I'm looking into that. Any help is appreciated.

  • Changing label color based on current label color in iPhone dev

    - by Matt Thomas
    I am having trouble figuring out the if statement code for changing the color of a UI label based on the current color of the label. For instance, if the label color is currently red and the correct button is pressed, I want the label color to change to black. If the label color is black I want the label color to change to blue. Many thanks for any tips.

  • How do i configure optional flags in MVC 1.0 routes

    - by Thomas Jespersen
    I want to configure a route with optional flags. E.g. I want to be able to call the products page and send optional filters (flags) for offers and in stock options. If the flags are NOT specified then all products should be returned. http://localhost/products http://localhost/products/onlyOnOffer http://localhost/products/onlyInStock http://localhost/products/onlyInStock/onlyOnOffer [AcceptVerbs(HttpVerbs.Get)] public ActionResult GetProducts(bool onlyInStock, bool onlyOnOffer) { //... } How would I configure the route? Is it even possible in MVC 1.0? What about MVC 2.0.

  • keep viewdata on RedirectToAction

    - by Thomas Stock
    [AcceptVerbs(HttpVerbs.Post)] public ActionResult CreateUser([Bind(Exclude = "Id")] User user) { ... db.SubmitChanges(); ViewData["info"] = "The account has been created."; return RedirectToAction("Index", "Admin"); } This doesnt keep the "info" text in the viewdata after the redirectToAction. How would I get around this issue in the most elegant way? My current idea is to put the stuff from the Index controlleraction in a [NonAction] and call that method from both the Index action and in the CreateUser action, but I have a feeling there must be a better way. Thanks.

  • How to lock non-browser clients from submitting a request?

    - by Thomas Kohl
    I want to block non-browser clients from accessing certain pages / successfully making a request. The website content is served to authenticated users. What happens is that our user gives his credentials to our website to 3rd party - it can be another website or a mobile application - that performs requests on his behalf. Say there is a form that the user fills out and sends a message. Can I protect this form so that the server processing the submission can tell whether the user has submitted it directly from the browser or not? I don't want to use CAPTCHA for usability reasons. Can I do it with some javascript?

  • Power Analysis in [R] for Two-Way Anova

    - by Thomas
    I am trying to calculate the necessary sample size for a 2x2 factorial design. I have two questions. 1) I am using the package pwr and the one way anova function to calculate the necessary sample size using the following code pwr.anova.test(k = , n = , f = , sig.level = , power = ) However, I would like to look at two way anova, since this is more efficient at estimating group means than one way anova. There is no two-way anova function that I could find. Is there a package or routine in [R] to do this? 2) Moreover, am I safe in assuming that since I am using a one-way anova power calculations, that the sample size will be more conservative (i.e. larger)?

  • Persisting cookie for iPhone UIwebview mobile web app

    - by Brad Thomas
    I'm using MVC4 forms auth. My mobile web app runs in full screen UIwebview on iphone. I have a home screen icon for my mobile web app. The app needs to launch external links. Those launch in Safari, which works fine. However returning to the mobile web app by clicking again on the home screen icon, seems to have logged the user out. Ideally I want the user to remain logged into the web app after viewing the external links in Safari. Maybe the cookie got deleted? Can I persist the cookie?

  • Unit testing that an event is raised in C#, using reflection

    - by Thomas
    I want to test that setting a certain property (or more generally, executing some code) raises a certain event on my object. In that respect my problem is similar to http://stackoverflow.com/questions/248989/unit-testing-that-an-event-is-raised-in-c, but I need a lot of these tests and I hate boilerplate. So I'm looking for a more general solution, using reflection. Ideally, I would like to do something like this: [TestMethod] public void TestWidth() { MyClass myObject = new MyClass(); AssertRaisesEvent(() => { myObject.Width = 42; }, myObject, "WidthChanged"); } For the implementation of the AssertRaisesEvent, I've come this far: private void AssertRaisesEvent(Action action, object obj, string eventName) { EventInfo eventInfo = obj.GetType().GetEvent(eventName); int raisedCount = 0; Action incrementer = () => { ++raisedCount; }; Delegate handler = /* what goes here? */; eventInfo.AddEventHandler(obj, handler); action.Invoke(); eventInfo.RemoveEventHandler(obj, handler); Assert.AreEqual(1, raisedCount); } As you can see, my problem lies in creating a Delegate of the appropriate type for this event. The delegate should do nothing except invoke incrementer. Because of all the syntactic syrup in C#, my notion of how delegates and events really work is a bit hazy. How to do this?

  • PowerShell script to restart a service

    - by Guy Thomas
    My mission is to press a keyboard sequence, such as Ctrl +Shift +R, to restart a Windows Service. I have a script which works fine in the PowerShell ISE, when launched with administrative privileges. When I try with a PowerShell script it fails due to insufficient Administrative Privileges. It’s galling that I can get it to work with an old-fashioned bat file, but not PowerShell. The root of the problem is that shortcuts to a PowerShell script have their Administrative privileges box greyed out. So far no work-around has overcome this privilege problem. Any ideas?

    This is the code in my DLL (C#): http://pastebin.com/Uirn0z2V I have the DLL built and inside both the JDK bin folder along with inside my project.

  • A little bit more complicated multiview App for Iphone

    - by Thomas Losert
    Hi, i'm new to iphone development. I spend several days by looking for how write muliview app for an Iphone OS. I found how to switch the diferent views without navigation hierarchy (in this article). It's great, but i want more complicated function. For example, i have three diferent views (view 1 - 3) and i can switch between them with technique from link 1. It works fine. My question is: How can i put UITabBarController on view 2, that shows own subviews (tabView 1 - 3) and how put UINavigationController on view 3, that shows own subviews (navView 1 - 2)? The reslut should look like that, one main view (view 1) with two buttons (for example), which switch me to "window" with UiTabBarController or UINavigationController. I found only tutorials, where UITabBarController was a first controller class, that shows directly from AppDelegate (something like default Xcode predefined scenarios). Thanks for your helpfull answer, or i will be crazy soon:).
