  • Getting a gestureoverlayview

    - by Codejoy
    I have been using some nice tutorials on drawing graphics on my android. I wanted to also add in the cool gesture demo found here: http://developer.android.com/resources/articles/gestures.html That takes these lines of code: GestureOverlayView gestures = (GestureOverlayView) findViewById(R.id.gestures); gestures.addOnGesturePerformedListener(this); This is fine and dandy yet I realize in my demo i'm trying to build using code from "Playing with Graphics in Android". The demos make sense, everything makes sense but I found out by using: setContentView(new Panel(this)); as is required by the Playing With Graphics tutorials, then the findViewById seems to no longer be valid and returns null. At first I was about to post a stupider question as to why this is happening, a quick test of playing with the setContentView made me realize the cause of findViewById returning null, I just do not know how to remedy this issue. Whats the key I am missing here? I realize that the new Panel is doinking some reference up but I am not sure how to make the connection here. THe: R.id.gestures is defined right int he main.xml as: (just like the tutorial) Thanks, Shane p.s. im new here be gentle.

  • Why do some websites add "Slugs" to the end of URLs?

    - by Dave Webb
    Many websites, including this one, add what are apparently called slugs - descriptive but as far as I can tell useless bits of text - to the end of URLs. For example, the URL the site gives for this question is: http://stackoverflow.com/questions/47427/why-do-some-websites-add-slugs-to-the-end-of-urls But the following URL works just as well: http://stackoverflow.com/questions/47427/ Is the point of this text just to somehow make the URL more user friendly or are there some other benefits?

  • How to save, retrieve and draw an image using Java and PostgreSQL?

    - by spderosso
    Given an object X; I want this object to have an image. The image must be stored in the database. I can't store the path, the actual image must be in the database. My question can be answered by answering the following subquestions: a). What type of field should I put in the database? (e.g VARCHAR) b) What type of object should I use for storing and manipulating the image (at an object layer)? (e.g java.awt.Image) c) How do I create an object of the type selected (answer of question b) from the data obtained from the database? d) How do I save an object of the type selected (answer of question b) to the database? e) How do I draw the image on a web page? I am using PostgreSQL, Java and it is a web application. Thanks!

  • Problem with reCaptcha and .NET

    - by vtortola
    Hi, I get this error with reCaptcha: 'Input error: response: Required field must not be blank challenge: Required field must not be blank privatekey: Required field must not be blank' I'm sending the data via POST, so I don't understand what is going on. This is the code I use: public static Boolean Check(String challenge, String response) { try { String privatekey = "7LeAbLoSAAAABJBn05uo6sZoFNoFnK2XKyF3dRXL"; String remoteip = HttpContext.Current.Request.UserHostAddress; WebRequest req = WebRequest.Create("http://api-verify.recaptcha.net/verify"); req.Method = "POST"; using (StreamWriter sw = new StreamWriter(req.GetRequestStream())) { sw.Write("privatekey={0}&remoteip={1}&challenge={2}&response={3}", privatekey, remoteip, challenge, response); sw.Flush(); } String resultString = String.Empty; String errorString = String.Empty; using (StreamReader sr = new StreamReader(req.GetResponse().GetResponseStream())) { resultString = sr.ReadLine(); errorString = sr.ReadLine(); } Boolean b; return Boolean.TryParse(resultString, out b) && b; } catch (Exception) { return false; } } (Of course that'is not the correct private key :P) I have no idea what the problem is about, I think I'm sending the data correctly, but that error says that apparently I'm not sending anything. What could be the problem? Cheers.

  • is struts2 Framework dead? if so, which direction to go from here?

    - by Omnipresent
    I've been working in struts2 framework for the past year and a half. As I look around SO it seems like struts2 questions get the least amount of hits. At first I thought it was because the SO community is not much into struts2, but this is the case in other forums as well. Only the struts2 mailing list is pretty active. I think struts2 is slowly becoming a dinosaur framework and I want to move on. I've dabbled a little with other stuff like RoR, Grails, Django, .NET MVC but I've never really committed and made a pact with myself to sit down and learn these. Maybe its the fact that I dont know the languages that these frameworks are built on. Spending a day or two with RoR makes me want to choke some of the JAR files and struts2 html tags and .NET MVC looks promising but not knowing c# ties me back. My question is, have you been on the same path? Did anyone used to do struts2 before and now changed to something new? What would you suggest I learn after Struts2? And lastly, as a developer how do you motivate yourself to learn a new framework, or a language? for me, just typing the code provided in the book is dead boring.

  • Check box and text box for Other value

    - by Svish
    When I have a set of either check boxes or radio buttons I often need to have an Other choice. This check box or radio button is very often accompanied by a text box where the user is supposed to fill out what this Other is. How do you usually handle this set up? What kind of markup do you use? What do you require in your validation? Do you use java script for anything? For example: How do you make the form accessible? Do you use and how do you use the label tag, for example. Do you connect the check box and text box in any way with some javascript? For example, do you activate the text box when the check box is checked? Do you check or uncheck the check box automatically if the text box is filled out or cleared? Do you let validation fail with error messages if the check box is checked but the text box is not filled out, or if the text box is filled out but the check box is not checked? Or do you just consider it not filled out and not checked? Very unsure how to best deal with this issue, so any advice and examples are most welcome c",)

  • Vsync in Flex/Flash/AS3?

    - by oshyshko
    I work on a 2D shooter game with lots of moving objects on the screen (bullets etc). I use BitmapData.copyPixels(...) to render entire screen to a buffer:BitmapData. Then I "copyPixels" from "buffer" to screen:BitmapData. The framerate is 60. private var bitmap:Bitmap = new Bitmap(); private var buffer:Bitmap = new Bitmap(); private function start():void { addChild(bitmap); } private function onEnterFrame():void { // render into "buffer" // copy "buffer" -> "bitmap" } The problem is that the sprites are tearing apart: some part of a sprite got shifted horizontally. It looks like a PC game with VSYNC turned off. Did anyone solve this problem? UPDATE: the question is not about performance, but about getting rid of screen tearing. [!] UPDATE: I've created another question and here you may try both implementations: using Flash way or BitmapData+copyPixels()

  • What's your all-time creativity problem?

    - by furtelwart
    Sometimes, you stumble with programming. Sometimes, it's a lack of creativity, sometimes, you need a new solution. But there are a lot of situations, you stick in, every time they occur. For myself, it's when I have to create the interface between model and viewer. I designed my data structure very well and drew a GUI prototype, but the missing link won't be written. What are your personal barricades in developing projects?

  • Wordpress form handling

    - by Ron
    I need to add a basic form page in the website, that runs on WordPress framework. I have the following raw materials ready: Client side: html form layout,css and jquery validation code. Server side: form handler php function that processes the $_POST[] data. My problem is to integrate this code in the Wordpress framework. I have looked at some plugins but they are doing much more than I would like and also they have their own validation which is cumbersome to change. Could anyone suggest a good form plugin that allows just the framework hooks ? Or is it worthwhile that I should write the plugin myself. Thanks.

  • Does Blogging affect Job Prospects?

    - by BM
    Would a hiring manager at a small-to-medium consulting firm/corporation consider active blogging by a candidate about Programming/software/technology as a positive? Should the candidate disclose this information during the interviews or put it on the resume? Thanks for the answers, So far the views about this topic has been.. Don't mention the blog if it is not relevant to the job. Mention the blog, if you believe your blog has quality content. Potential risk of not being accepted by culture of the employer's workplace. Could be a valuable for consultants to publish & preview their skills and experience. Certain Employers may consider blogging of a candidate a plus. Be careful what you post on the blog,no badmouthing,rants and overt criticism of others. Do not lie about blogging,if directly asked during the interview.

  • reinventing the wheels: Node.JS/Event-driven programming v.s. Functional Programming?

    - by ivanTheTerrible
    Now there's all the hype lately about Node.JS, an event driven framework using Javascript callbacks. To my limited understanding, its primary advantage seems to be that you don't have to wait step by step sequentially (for example, you can fetch the SQL results, while calling other functions too). So my question is: how is this different, or better than just functional languages, like CL, Haskell, Clojure etc? If not better, then why don't people just do functional languages then (instead of reinventing the wheel with Javascript)? Please note that I have none experience in either Node.JS nor functional programming. So some basic explanation can be helpful.

  • Asp.net Webdeployment Project override applicationSettings

    - by citronas
    I got a web deyploment project for a web application project in vs 2008. While building the web deployment project, I want to replace properties in the web.config. My settings are autogenrated by the deisgner. <applicationSettings> <NAMESPACE.Properties.Settings> <setting name="Testenvironment" serializeAs="String"> <value>True</value> </setting> </NAMESPACE.Properties.Settings> </applicationSettings> In the config file which contains the settings for the specific server looks like the following: <?xml version="1.0"?> <applicationSettings> <NAMESPACE.Properties.Settings> <setting name="Testenvironment" serializeAs="String"> <value>False</value> </setting> </NAMESPACE.Properties.Settings> </applicationSettings> Sadly, this does not work. I get an error "The format of a configSource file must be an element containing the name of the section" that highlights the second line (2nd example code). How must the Tag be named in order to make evertything work? Edit: Deleting the "applicationSetting"-Tags does not work either.

  • Where is the node.js file in the stack trace located?

    - by user225189
    Obviously, I'm pretty new to node.js. I'm attempting to debug a node.js application and I see node.js in the stack trace. I would like to put some sys.puts calls in there, but I cannot locate the node.js that is being run by my server. Is there a way to tell where node.js is located? Is there an equivalent to Ruby's FILE in node? Thanks, Brian
