  • Build Path issue with Java Android project when starting Eclipse

    - by Matt Smith
    I booted up eclipse to start on a project, and without typing in a word I already have several errors. package department.namespace; import android.app.Activity; import android.os.Bundle; public class DepartmentActivity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } } At package department.namespace, it says: multiple marks at this line and the type java.lang.Object cannot be resolved. It is indirectly referenced from required .class files The import android.os cannot be resolved. Override cannot be resolved as a type The method OnCreate(Bundle) is undefined for the type Activity R. cannot be resolved as a variable. Since this JUST came up when I started Eclipse, how do I fix this?

  • Structs inside #define in C++

    - by Adam Smith
    Being pretty new to C++, I don't quite understand some instructions I encounter such as: #ifndef BOT_H_ #define BOT_H_ #include "State.h" /* This struct represents your bot in the game of Ants */ struct Bot { State state; Bot(); void playGame(); //plays a single game of Ants void makeMoves(); //makes moves for a single turn void endTurn(); //indicates to the engine that it has made its moves }; #endif //BOT_H_ What I don't understand is the "#ifndef BOT_H_" and the "#define -- #endif" From what I gather, it defines a constant BOT_H_ if it's not already defined when the precompiler looks at it. I don't actually get how the struct inside it is a constant and how it is going to let me access the functions inside it. I also don't see why we're doing it this way? I used C++ a while back and I wasn't using .h files, so it might be something easy I'm missing.

  • Creating "GDP in 1960" variable from GDP variables for different years

    - by Tom Smith
    Hi all, I'm pretty new to stata... I have a set of observations of the form "Country GDP Year". I want to create a new variable GDP1960, which gives the GDP in 1960 of each country for each year: USA $100m 1960 USA $100m 1960 $100m USA $200m 1965 --> USA $200m 1965 $100m Canada $60m 1960 Canada $60m 1960 $60m What's the right syntax to make this happen? (I assume egen is involved in some mysterious way)

  • sort associative array PHP

    Here's my array, how do I sort it by saleref?

  • Facebook Like button - comment box with breif description and image

    - by Dave Smith
    On my website when the user selects the facebook like button they have the option to enter comments. This popup window to enter comments only contains the users avatar and place to enter comments. How can i include my pic and a brief description of the site directly below the comment??? At first I thought it was from the HTML title attribute or meta property="og:title" ... but populating these have no affect I have another site that contains both pic and a desc below the comment but the pic seems to be grabed at random -but always the same- from the site and the short desc I thought from the -title- attribute but its not - I changed the -title- and it still shows the same desc, its like its cached??? Any ideas how to control or populate a brief description and image within the comment section of a like button???

  • Is locking on the requested object a bad idea?

    - by Quick Joe Smith
    Most advice on thread safety involves some variation of the following pattern: public class Thing { private static readonly object padlock = new object(); private string stuff, andNonsense; public string Stuff { get { lock (Thing.padlock) { if (this.stuff == null) this.stuff = "Threadsafe!"; } return this.stuff; } } public string AndNonsense { get { lock (Thing.padlock) { if (this.andNonsense == null) this.andNonsense = "Also threadsafe!"; } return this.andNonsense; } } // Rest of class... } In cases where the get operations are expensive and unrelated, a single locking object is unsuitable because a call to Stuff would block all calls to AndNonsense, degrading performance. And rather than create a lock object for each call, wouldn't it be better to acquire the lock on the member itself (assuming it is not something that implements SyncRoot or somesuch for that purpose? For example: public string Stuff { get { lock (this.stuff) { // Pretend that this is a very expensive operation. if (this.stuff == null) this.stuff = "Still threadsafe and good?"; } return this.stuff; } } Strangely, I have never seen this approach recommended or warned against. Am I missing something obvious?

  • Could someone give me their two cents on this optimization strategy

    - by jimstandard
    Background: I am writing a matching script in python that will match records of a transaction in one database to names of customers in another database. The complexity is that names are not unique and can be represented multiple different ways from transaction to transaction. Rather than doing multiple queries on the database (which is pretty slow) would it be faster to get all of the records where the last name (which in this case we will say never changes) is "Smith" and then have all of those records loaded into memory as you go though each looking for matches for a specific "John Smith" using various data points. Would this be faster, is it feasible in python, and if so does anyone have any recommendations for how to do it?

  • Why does Apple create it's views this way

    - by John Smith
    In the hope of fixing a bug of mine from another post i would like to know why apple writes this (for it's Elements example) UIView *localContainerView = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; self.containerView = localContainerView; [localContainerView release]; instead of the simpler method: containerView = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; ?

  • How to manage lifecycle in a ViewGroup-derived class?

    - by Scott Smith
    I had a bunch of code in an activity that displays a running graph of some external data. As the activity code was getting kind of cluttered, I decided to extract this code and create a GraphView class: public class GraphView extends LinearLayout { public GraphView(Context context, AttributeSet attrs) { super(context, attrs); LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); inflater.inflate(R.layout.graph_view, this, true); } public void start() { // Perform initialization (bindings, timers, etc) here } public void stop() { // Unbind, destroy timers, yadda yadda } . . . } Moving stuff into this new LinearLayout-derived class was simple. But there was some lifecycle management code associated with creating and destroying timers and event listeners used by this graph (I didn't want this thing polling in the background if the activity was paused, for example). Coming from a MS Windows background, I kind of expected to find overridable onCreate() and onDestroy() methods or something similar, but I haven't found anything of the sort in LinearLayout (or any of its inherited members). Having to leave all of this initialization code in the Activity, and then having to pass it into the view seemed like it defeated the original purpose of encapsulating all of this code into a reusable view. I ended up adding two additional public methods to my view: start() and stop(). I make these calls from the activity's onResume() and onPause() methods respectively. This seems to work, but it feels like I'm using duct tape here. Does anyone know how this is typically done? I feel like I'm missing something...

  • HttpWebRequest possibly slowing website

    - by Steven Smith
    Using Visual studio 2012, C#.net 4.5 , SQL Server 2008, Feefo, Nopcommerce Hey guys I have Recently implemented a new review service into a current site we have. When the change went live the first day all worked fine. Since then though the sending of sales to Feefo hasnt been working, There are no logs either of anything going wrong. In the OrderProcessingService.cs in Nop Commerce's Service, i call a HttpWebrequest when an order has been confirmed as completed. Here is the code. var email = HttpUtility.UrlEncode(order.Customer.Email.ToString()); var name = HttpUtility.UrlEncode(order.Customer.GetFullName().ToString()); var description = HttpUtility.UrlEncode(productVariant.ProductVariant.Product.MetaDescription != null ? productVariant.ProductVariant.Product.MetaDescription.ToString() : "product"); var orderRef = HttpUtility.UrlEncode(order.Id.ToString()); var productLink = HttpUtility.UrlEncode(string.Format("myurl/p/{0}/{1}", productVariant.ProductVariant.ProductId, productVariant.ProductVariant.Name.Replace(" ", "-"))); string itemRef = ""; try { itemRef = HttpUtility.UrlEncode(productVariant.ProductVariant.ProductId.ToString()); } catch { itemRef = "0"; } var url = string.Format("feefo Url", login, password,email,name,description,orderRef,productLink,itemRef); var request = (HttpWebRequest)WebRequest.Create(url); request.KeepAlive = false; request.Timeout = 5000; request.Proxy = null; using (var response = (HttpWebResponse)request.GetResponse()) { if (response.StatusDescription == "OK") { var stream = response.GetResponseStream(); if(stream != null) { using (var reader = new StreamReader(stream)) { var content = reader.ReadToEnd(); } } } } So as you can see its a simple webrequest that is processed on an order, and all product variants are sent to feefo. Now: this hasnt been happening all week since the 15th (day of the implementation) the site has been grinding to a halt recently. The stream and reader in the the var content is there for debugging. Im wondering does the code redflag anything to you that could relate to the process of website? Also note i have run some SQL statements to see if there is any deadlocks or large escalations, so far seems fine, Logs have also been fine just the usual logging of Bots. Any help would be much appreciated! EDIT: also note that this code is in a method that is called and wrapped in A try catch UPDATE: well forget about the "not sending", thats because i was just told my code was rolled back last week

  • C++ - Access array (in main) from methods outside main

    - by John Smith
    I have an array in my main class that holds objects that I need to print out for a menu listing. The array is declared and initialized in main. I need to, however, access the same array in a sub-menu function. If I copy the code (for loop that prints out the values) to the sub-menu, nothing is printed (presumably because it can't access the original array and has made a new, blank one). Is there any way (without making the array a global variable) that I can access the array in this sub-menu? Both the main and the sub-menu function are in the same file and the sub-menu is called from main. Maybe to put it more simply, can I use scope resolution to bring me up one 'level' in scope?

  • Is it possible to virtualize war file execution without separate J2EE container deployments?

    - by Smith
    Let's say I want to allow my developers to upload their war files to a web app (not the application server itself) running on our intranet and that web app would then run those wars as if they were separate apps deployed individually in our J2EE container. In other words, we are not actually deploying the wars as separate apps in the container - they are simply running side-by-side inside this one web app that acts like a J2EE container. Is that possible? Something like a war virtualization app?

  • Jquery return element html instead of content

    I have something like this <ul> <li class="aclass" id="a">content</li> <li class="aclass" id="b">content</li> <li class="aclass" id="c">content</li> <li class="aclass" id="d">content</li> <li class="aclass" id="e">content</li> <li class="aclass" id="f">content</li> </ul> I have code like $(".aclass").live("mousedown",function() { alert($this.html()); }); This will alert the content, what I would like to do is alert the entire element like <li class="aclass" id="f">content</li> I've tried $(this).parent() but that returns the whole UL

  • How do you have grayed out text in a textfield that dissapears when the user clicks on it

    - by John Smith
    In HTML & JS, how do you make a textfield that has grayed out text telling the user what the field is for that goes away when the user clicks on the field? For example, in firefox the search field in the top right hand side says which search engine it uses when there's nothing entered, then once you click it's an empty textfield, but if you leave it blank and remove focus from the textfield then the grayed out text is back again. Is there a name for this behavior? Also, is it possible to do in pure css without the use of js to do the on focus / on blur events?

  • How to add value to second column using wxListCtrl in wxWidgets (C++ code)??

    - by azm882
    I've following code: int column_width = 100; long indx1 = alist-InsertColumn(0, L"User Name", wxLIST_FORMAT_LEFT, column_width); long indx2 = alist-InsertColumn(1, L"User Id", wxLIST_FORMAT_LEFT, column_width); long itemIndex1 = alist-InsertItem(indx1, L"John Smith", -1); alist-SetItem(indx1, 1, L"jsmith"); I expect to see two columns with User Name and User Id as heading with "My Name" and "My Id" as values on the first row. Instead I only see "John Smith" under column User Name but nothing under User ID column. Here is a link to the snapshot showing the result: http://drop.io/agtyt6s Thanks!

  • Creating a contact form using divs with 4 extra divs for "Corners"?

    - by mark smith
    Hi there, i have tried to create a contact form (a standard form, square in nature but with rounded corners)... I can't use the CSS3 specs so i have an image for each corner.. I have set the images on the background-image and no repeat but it seems if the div is empty then it doesn't display, is there a hack - although prefer an alternative clean method :-) So on the top level i presume i have 1 div for the Upper-Left (corner) and then the upper-middle (just has a color assigned) and then a div for the upper-right (corner) .. so i presume i need to float all these to the left??? Or am i missing something? Thanks in advance

  • Running Services.msc as a different User C#

    - by Simon Mark Smith
    Hi, I have a requirement to create a simple windows forms application that allows an admin user to manage the Services on remote servers. We don't want to give the admins the usernames and passwords to the servers so these will be encrypted and stored in a database. My question is whether or not it is possible to spawn a Services.msc window when impersonating one of the users stored within the database? I have looked at the ProcessStartInfo class but because Services.msc is not an executable it does not seem to like executing this. Any ideas on a simple way of doing the actual impersonation and loading of Services.msc - say off a button click? Thanks

  • Android : Stop image scaling down

    - by John Smith
    Hi, I'm trying to draw an image in a view but having problems trying to maintain the scale of the original image. Basically, I have a small view and I would like to show part of the image in the view. The intention then is to perform a translation on the image so that a different part appears in the view. No matter what I try, either the image is down-scaled automatically to fit the view or the whole image is viewable. I've tried playing about with the settings on BitmapDrawable, ImageView and Layout to no avail. Anyone know a good way to achieve this?

  • Configuring the GPS Intermediate Driver

    - by Zach Smith
    Hello, I have a Motorola MC75 with an integrated GPS system that I am trying to use for programming. I have done some research on it and tried setting it up by editing the remote registry of the device according to some specifications that I found on the internet on this blog, http://csharponphone.blogspot.com/2007/07/configuring-gps-intermediate-driver.html. I used the smart phone guide at the bottom of the page but to no avail. Currently, I am trying to test it with the GPS application provided in the Windows Mobile 6 SDK samples. The program will load and begin what looks like the search for satellites but will not locate anything. I do not think the GPS is set up correctly. Does anyone have any helpful insight onto this issue or a guide for configuring the GPSID? Thank you in advance. Also, I have already checked and tried some of the config help on MSDN which does not help me either. I will surely vote for the most helpful answer. Thanks, Zach
