 | That's just the nature of social media promotions, you will always have followers and unfollowers. If people find no value in your posts, they will unfollow you. As a rule, people do not like it if they get spammed with advertisements or promotions all the time. Also, if you keep …  |
 | Live chat creates a sense of community and makes websites appear more personnel. It's all fine and dandy to be able to send a support mail, but having the opportunity to chat to an expert, and recieve realtime feedback is of tremendous value. People have come to expect fast results, … |
 | I don't see the file attachment, so it's difficult to answer.  |
| | Hi. You are referencing R.id.container - but none of your components are called that. It looks like you are missing something from whatever tutorial you are using. I can assure you that everything is not as it is in the tutorial :) - that code won't compile, thre's nothing with … |
| | You can try this window.setTimeout(function() { $("#myweb").load("webcamsnap.php"); }, 2000); Inside your function. It will make the load wait 2 seconds before actually executing it. |
| | Re: rotate array Is there any particular reason you are not using the Java Stack collection? See [Java Stac](http://docs.oracle.com/javase/7/docs/api/java/util/Stack.html) for some help. I don't see the value in building your own stack collection, unless it's a homework exercise, in which case you need to struggle with it :)  |
| | Well, 400 means your request is bad. Have you traced your POST and taken a look at the actual request that is sent? Using [Charles Proxy](http://www.charlesproxy.com/), you can easily see what request are being sent, and then see where the problem is. |
 | The VX670 runs an ARM 32bit chip, and, according to the data sheet, has about 6mb of RAM. There are some mention in the reference manual of writing your own applications, but they are quite vague and it does seem to be C / C++ related, not Java. Look at … |
 | Hi, by default, the Android WebView opens links in the system browser. You need to override this (see [Click Here](http://developer.android.com/guide/webapps/webview.html)) to change the behaviour. Use this code: webView.setWebViewClient(new WebViewClient() { @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { return false; } }); Basically, returning false on this request tells the … |
| | Your JavaScripts are over-writing each other. Wrap them in anynomous functions, like so : http://plnkr.co/edit/B6265864pZhZOsXGkBqL?p=preview Basically, you want to wrap your entire JS in (function(){ ..... your code ..... })(); This will protect the methods from each other. When I do that, I have two working canvas elements. |
| | This is actually a very rarely used feature, so finding documentation on it is difficult. I, for one, believe that sending a username and a password this way is risky, but, if you really need to do so, you can modify the SOAP header request. The trick is to create … |
| | The best way is to expose some kind of web service or API that your Android app can talk to. Directly connecting a mobile application to a database is not a good idea, you have so many connectivity issues to deal with that it becomes a nightmare to ensure data … |
| | Re: Applet Ah, you want the two applets to be able to communicate with each other. You can do it with JavaScript, there's a very nice tutorial here : http://docs.oracle.com/javase/tutorial/deployment/applet/iac.html The basic idea is to use the parent page's JavaScript context to pass messages between the two applets, because the page can … |
| | You will need to take measurements as to the current disk consumption over a period of a month, every day, more or less at the same time. That will give you a daily disk consumption rate. Then work on an average of 125% of that rate and you'll have a … |
| | There's no easy way to answer this without knowing how complicated an application you are referring to. Which platform are you targetting? Is this a mobile application for Android, iPhone, Windows Phone, Nokia S60, Blackberry... Does the mobile site already exist? Do you need the mobile app to interact with … |
| | Your subject and question are not the same, which one do you need answered? I'm not sure :) |
| | There's a great explanation athttp://www.cems.uwe.ac.uk/~jsa/UMLJavaShortCourse09/CGOutput/Unit9/unit9%280809%29/page_03.htm with a good example as well. |
 | Ah, the Google Play store has a once-off cost, which means that once you've registered, you never pay again, even if you publish 1000 applications. Please visit http://developer.android.com/tools/publishing/publishing_overview.html and http://developer.android.com/distribute/googleplay/publish/preparing.html to get the most recent and relevant information. The current cost to register is $25 (twenty five US Dollars). This … |
| | Depending on what you wish to do, you might make use of technologies like PhoneGap or Titanium Appcelerator to write a single program that works on both iOS or Android. As RubberMan pointed out, these two platforms have applications that are built using a different technology stack, but for high-performance …  |
| | Ah, this sounds like quite the conundrum - "Here type this - oh wait, no keyboard" seems to be what I keep running into. Can you boot into command-prompt mode only? And does the keyboard work from there? I've had a machine with a very similar issue, and it turned … |
| | Re: Using php cli I use "php" when I try to run php commands using the xampp distribution. For example, ignoring the path : C:\xampp\php\php.exe myphpfile.php would execute the myphpfile.php script. |
| | You'll need a build a basic API on the server side that handles all calls and provides a RESTful interface for the Android app. That's one way to do it - and I'd certainly recommend going this route. You can then use a simple Android client to make REST calls … |
 | The most likely reason is that there's still a thread that is running in the background. In Java, all GUI applications have at least two threads - the application itself and the GUI. In Swing, for example, you must specify the EXIT_ON_CLOSE flag for your top-level frame, otherwise the GUI …  |
| | Hi. Sorry I only saw this now. Let's take it line by line: 1. create a static method called analyAPI that takes a single parameter, pkgname. In Groovy, you do not have to specify the variable type, just the name, very much like in JavaScript. 3. Define a variable called … |
| | Apart from the fact that the above code won't compile, nor run, you neglected to show HOW the append() method works, so we can't really help you there. I'd have to venture a guess and say that you do not grow the linked list correctly, but that's impossible to be … |
| | Re: Live wallpapers You are correct. A live wallpaper is just an application, just with special privileges. You can certainly build in date-driven behaviour. I've found Java to be the best language for doing this kind of development for Android. |
| | That's one of the things that most search engines look for to disqualify you with! |
| | Are you running through every pixel at a time? How about using a scaling algorithm rather? Let's say, each entry in your grid equals 4 real pixels. Then you already have 1/4 of the number of calculations to do. I don't think that on a game like that, you really … |
| | Hi. Even while using a cloud solution, you will have some data on your machine that is sensitive. The best approach, even with a cloud host, is to encrypt your hard drive. Under Windows, you can use something like Check Point (http://www.checkpoint.com/products/full-disk-encryption/index.html) that will encrypt the entire drive. I know … |
| | If you end up selling to a company like Google, they will definitely have a nice contract they want you to sign. That contract will, amongst other things : - Transfer all intellectual property (code, design, names etc.) to them. - Have a restraint of trade in place to prevent … |
| | Hi. I've had good success opening XLS files with http://poi.apache.org/ - as for printing, that's entirely up to you. You will need to read the data and then send it to the printer. |
 | Ok Rina, I'm sure we can help when you get stuck, but you are going to have to do a lot of planning and put in some effort. Nobody's just going to do your homework for you. Show us what you've done, where you are stuck and where we can … |
| | Do you have anything besides the Python script that can read the data? It might be worth your while to investigate whether the dataloss is related to your script or not, because right now, there are too many unknowns. |
| | Hi, dont' worry, this is a common issue with learning Java : Monster.Java should be called Monster.java. Java is case sensitive, so when it tries to find the Monster.java file, it's failing due to the naming issue. Rename it to Monster.java and it should be fine. (You can right-click on … |

| | This service has been deprecated and is no longer available. The guys at http://www.xignite.com/ have a free trial you can use. What I've found with free sotck information services is that they are very slow and inaccurate, so for commercial use, they are not a good choice. |
 | You can use the Java Desktop libraries (see http://docs.oracle.com/javase/tutorial/uiswing/misc/desktop.html) to do exactly this. There's even some good examples, and the best thing is, it works cross-platform as well. |
| | Touch screen displays for PC's. It's both an input and a display device. While it's not a new invention, it's only recently become popular. |
 | Re: Career choice? Why would you split the two? My biggest pain is with the lack of security in cloud solutions. If you look at companies like Amazon, they dedicate a serious amount of time and effort to cloud architecture, but not nearly the same amount of effort to security. The reason for …  |
 | Re: help Hi. I'm not entirely sure what your question is. Perhaps you need to make a list of what you want / need this program to do, that way, you can break it down into simple steps and develop them one by one, making your life easier. How would you like …  |
| | In Android Studio, you will have a Logcat view which will give you a stack trace of the exception. We'll need that to figure out where what goes wrong. |
| | Indexes... You do not have indexes on the columns you are comparing, so it will be doing table scans all the time. Simply create indexes on both tables, for those columns, before you run the query. |
| | Migrating from one database to another is never a smooth operation, you might be setting yourself up for a lot of effort. Plus the licenses required for MS-SQL might be quite heavy, which is going to have an impact on the sustainability of such a project. Honestly, what you are … |
 | Natural language generation is a rather advanced topic. Do you need the text to just LOOK natural, as in what is generated by http://www.lipsum.com/ or do you want actual English, as an example langauge? Generating text that looks natural is hard enough, generating readible, sensible language is a bit tougher. … |
 | Re: beginner Well, that depends on what you mean by mobile development. Do you mean mobile applications, mobile-friendly websites, native applications, hybrid applications? And, most importantly, which platform do you want to start with? Windows phone, iPhone, Android, Blackberry, J2ME... This is a tremendously large field, I suggest figuring out what you … |
| | I've had tremendous success using a bit of a cheat - I have a Python script that fires and generates HTML pages that are served on a Raspberry Pi (very similar to your setup) that includes JSON data required to draw charts with http://www.chartjs.org/ - This job fires every few … |
| | Are you 100% sure that you actually have data in your array? |
 | You might want to check the power management settings in the BIOS. On some machines, you need to enable power management by the OS, otherwise it doesn't allow the OS to shut down the machine completely.  |
 | If you are using the old heatsink, remember, it might not be transferring heat fast enough for the new CPU. Did you thoroughly clean the old heatsink before reusing it? It's critical that you remove all heat-conductive paste first, then apply sufficient, new paste before applying an older heatsink to …  |
| | The first error is easy - you are not specifying a return type. In Java, only constructors do not specify return types. Did you copy and paste this code into a new .java file? It looks like the original file was called MineCraftLoginReader.java - but you've changed that. Java requires … |
The End.
