  • Launch Google Maps app

    - by oriharel
    Hi, I'm trying to launch Google maps from my application. I'm using: GeoPoint center = _mapView.getMapCenter(); Uri uri = Uri.parse("geo:"+center.getLatitudeE6()+","+center.getLongitudeE6()); Log.d(LOG_TAG, "Launching Google Maps with Uri: ("+uri+")"); Intent intent = new Intent(Intent.ACTION_VIEW, uri); startActivity(intent); I tested it with a map centered on somewhere in NYC, however Google maps opens not centered there. I followed Android Developer's site reference to use: "geo:latitude,longitude" pattern. the log that you see prints: Launching Google Maps with Uri: (geo:40763500,-73979305) anyone knows what can be the problem?

  • WCF RIA Services and RFCs

    - by Kottan
    I want (have) to write a Silverlight and (or) ASP.NET based webapplication with SAP in the backend (in other words, the datasource is no classical database) . The usage of Silverlight and ASP.NET is a precondition. Is it possible to use the WCF RIA Services (and Silverlight) where the data-source are RFCs from SAP ? Makes this sense ? If yes, how the pattern/architecture could be shortly described ? Or should I take other architectures into considerations (usage of plan WCF services, WCF data services,...) ?

  • Join collection of objects into comma-separated string

    - by Helen Toomik
    In many places in our code we have collections of objects, from which we need to create a comma-separated list. The type of collection varies: it may be a DataTable from which we need a certain column, or a List<Customer>, etc. Now we loop through the collection and use string concatenation, for example: string text = ""; string separator = ""; foreach (DataRow row in table.Rows) { text += separator + row["title"]; separator = ", "; } Is there a better pattern for this? Ideally I would like an approach we could reuse by just sending in a function to get the right field/property/column from each object.

  • Why should I use MVVM when it breaks built in riaservices functionality

    - by Jakob
    I'm struggling to grasp why MVVM is really a good pattern to implement in riaserivces, To me there's nothing but trouble to it, it just add's another tier that I have to code. I Get that I could change the UI, but really I don't need to. Instead i won't be able to user out of the box functionality with riaservices, datagrid, dataform all controls require some implementation. Why can't it just be simple? Is there really no way to get MVVM to automatically set "IsBusy" and all the dataform edit functionality. It's like reinventing the wheel to me, and it seems that I'd be able to write code much faster just using riaservices

  • how to move and print squares visited by a knight in following order?

    - by josh kant
    Lets say you have a 5/5 board and you place and the knight started moving form the middle square. Every time knight moves it has to follow the following pattern. its easy if you draw what i mean. I am trying to code for the possible moves and print out the no. of moves in the nXn (in this case 5X5) board. The print out should be the no. of order in which the knight moved. { //move 1 //2 squares up and 1 to the left //move 2 //2 squares up and 1 to the right //move 3 //1 square up and 2 to the right //move 4 //1 square down and 2 to the right //move 5 //2 squares down and 1 to the right //move 6 //2 squares down and 1 to the left //move 7 //1 square down and 2 to the left //move 8 //one square up and 2 to the left } Any help would be appreciated. Thank you in advance..

  • Link to RSS/Atom feed, relative, doesn't work in Firefox

    - by Adrian Smith
    I have a weird problem. I generate a HTML page, hosted let's say at http://www.x.com/stuff which contains <head> <link type="application/atom+xml" rel="alternate" href="/stuff/feed"/> .. </head> The result is: In IE7 all works well - you can click on the feed icon in the browser and the feed is displayed In Firefox, view source, click on the linked /stuff/feed and you see the source of the feed, so that works as expected In Firefox, view the page (not source), then click on the feed icon in the address bar, I get an error that it can't retrieve the URL feed://http//www.x.com/stuff/feed So the problem is, that it's appending feed:// to the front of the URL and then taking out the colon : after the http. I understand that feed: is HTTP anyway so perhaps the adding of that isn't a big problem. But anyway, the fact is, that URL Firefox generates out of my <link> tag doesn't work. I have considered making the URL absolute, but I haven't found any evidence that those URLs have to be absolute, nor can I understand why that would be the case. And for various reasons it would be inconvenient in my code to generate an absolute URL. I can do it if necessary but I would prefer to see proof (e.g. specification, or Mozilla bug report) that it's necessary before making my code messy What do you think? Does anyone know of any evidence that the URL should be absolute? Or am I doing something else wrong? It seems such a simple/obvious tag, where nothing could go wrong, but I can't get it to work.

  • Boiler plate code replacement - is there anything bad about this code?

    - by Benjol
    I've recently created these two (unrelated) methods to replace lots of boiler-plate code in my winforms application. As far as I can tell, they work ok, but I need some reassurance/advice on whether there are some problems I might be missing. (from memory) static class SafeInvoker { //Utility to avoid boiler-plate InvokeRequired code //Usage: SafeInvoker.Invoke(myCtrl, () => myCtrl.Enabled = false); public static void Invoke(Control ctrl, Action cmd) { if (ctrl.InvokeRequired) ctrl.BeginInvoke(new MethodInvoker(cmd)); else cmd(); } //Replaces OnMyEventRaised boiler-plate code //Usage: SafeInvoker.RaiseEvent(this, MyEventRaised) public static void RaiseEvent(object sender, EventHandler evnt) { var handler = evnt; if (handler != null) handler(sender, EventArgs.Empty); } } EDIT: See related question here UPDATE Following on from deadlock problems (related in this question), I have switched from Invoke to BeginInvoke (see an explanation here). Another Update Regarding the second snippet, I am increasingly inclined to use the 'empty delegate' pattern, which fixes this problem 'at source' by declaring the event directly with an empty handler, like so: event EventHandler MyEventRaised = delegate {};

  • emacs23 pops up debugger way too frequently

    - by werner r.
    Since I've upgraded to Ubuntu lucid and emacs23, Emacs pops up the debugger in situations, where emacs22 does not. For example, when hitting C-c C-c in org-mode, emacs22 simply states can do nothing useful at this location, whereas in emacs23 the debugger shows up. Debugger entered--Lisp error: (error "C-c C-c can do nothing useful at this location") signal(error ("C-c C-c can do nothing useful at this location")) error("C-c C-c can do nothing useful at this location") org-ctrl-c-ctrl-c(nil) call-interactively(org-ctrl-c-ctrl-c nil nil) That only illustrates the pattern -- the behavior is not limited to org-mode. Occurring every 3 minutes, it really annoys me. How can I prevent it? I've already tried to stop this using debug-on-error and stack-trace-on-error: it didn't work.

  • Scite Lua - escaping right bracket in regex?

    - by ~sd-imi
    Hi all, Bumped into a somewhat weird problem... I want to turn the string: a\left(b_{d}\right) into a \left( b_{d} \right) in Scite using a Lua script. So, I made the following Lua script for Scite: function SpaceTexEquations() editor:BeginUndoAction() local sel = editor:GetSelText() local cln3 = string.gsub(sel, "\\left(", " \\left( ") local cln4 = string.gsub(cln3, "\\right)", " \\right) ") editor:ReplaceSel(cln4) editor:EndUndoAction() end The cln3 line works fine, however, cln4 crashes with: /home/user/sciteLuaFunctions.lua:49: invalid pattern capture >Lua: error occurred while processing command I think this is because bracket characters () are reserved characters in Lua; but then, how come the cln3 line works without escaping? By the way I also tried: -- using backslash \ as escape char: local cln4 = string.gsub(cln3, "\\right\)", " \\right) ") -- crashes all the same -- using percentage sign % as escape chare local cln4 = string.gsub(cln3, "\\right%)", " \\right) ") -- does not crash, but does not match either Could anyone tell me what would be the correct way to do this? Thanks, Cheers!

  • Code Golf: Beehive

    - by LiraNuna
    The challenge The shortest code by character count that will generate a beehive from user input. A beehive is defined a a grid of hexagons in a size inputted by the user as two positive numbers greater than zero (no need to validate input). The first number (W) represents the width of the beehive - or - how many hexagons are on each row. The second number (H) represents the height of the beehive - or - how many hexagons are on each column. A Single hexagon is made from three ASCII characters: _, / and \, and three lines: __ / \ \__/ Hexagons complete each other: the first column of the beehive will be 'low', and the second will be high - alternating and repeating in the same pattern forming W hexagons. This will be repeated H times to form a total of WxH hexagons. Test cases: Input: 1 1 Output: __ / \ \__/ Input: 4 2 Output: __ __ __/ \__/ \ / \__/ \__/ \__/ \__/ \ / \__/ \__/ \__/ \__/ Input: 2 5 Output: __ __/ \ / \__/ \__/ \ / \__/ \__/ \ / \__/ \__/ \ / \__/ \__/ \ / \__/ \__/ Input: 11 3 Output: __ __ __ __ __ __/ \__/ \__/ \__/ \__/ \__ / \__/ \__/ \__/ \__/ \__/ \ \__/ \__/ \__/ \__/ \__/ \__/ / \__/ \__/ \__/ \__/ \__/ \ \__/ \__/ \__/ \__/ \__/ \__/ / \__/ \__/ \__/ \__/ \__/ \ \__/ \__/ \__/ \__/ \__/ \__/ Code count includes input/output (i.e full program).

  • JQuery: NOT using document.ready and inserting HTML Tags = is this allowed?

    - by jens
    Hello, is this a valid JQuery usage pattern to : <script type="text/javascript"> $("body").prepend('<input type="hidden" id="error" value="show">'); </script> That is using Jquery to manipulate / insert HTML Tags when the Document has NOT YET been loaded (by not using document.ready for the inserting into the DOM)? (Normally I only use document.ready, but in this case I need to insert some Information into the DOM that then is present, when document.ready is called. This is some kind of "happens-before" relations ship I want to achieve so that I am shure when document.ready is called the inserted Form field is available in the document, as I depend on that information. Thank you very much jens

  • Traditional loop versus Action delegate in C#

    - by emddudley
    After learning about the Action delegate in C# I've been looking for ways I can best use it in my code. I came up with this pattern: Action<string> DoSomething = (lSomething) => { // Do something }; DoSomething("somebody"); DoSomething("someone"); DoSomething("somewhere"); If I were to have used a traditional loop, it would look something like this: List<string> lSomeList = new List<string>(); lSomeList.Add("somebody"); lSomeList.Add("someone"); lSomeList.Add("somewhere"); foreach (string lSomething in lSomeList) { // Do something } Are there any appreciable differences between the two? To me they look equally easy to understand and maintain, but are there some other criteria I might use to distinguish when one might be preferred over the other?

  • Flex TextArea leading invalid

    - by Andreas
    Hi, When I set leading to 0 with Verdana (and others to) for a Flex TextArea I get strange results: fontsize - space between baselines 8 - 10 (125%) 10 - 12 (120%) 12 - 14 (117%) 14 - 17 (121%) 16 - 18 (113%) 18 - 22 (122%) 20 - 25 (125%) 25 - 31 (124%) shouldn't all of these be the same (should only be 100%)? Or least follow a pattern, because I can't se any. :( When i set leading to 0, the space between my baselines should be the same as the font size/height. This is not the case here. How do I know how to get the space between the baseline to be equal to the height of the font?

  • Regex to detect a proper permalink?

    - by Fedor
    These permalinks above are rerouted to my page: page.php?permalink=events/foo page.php?permalink=events/foo/ page.php?permalink=ru/events/foo page.php?permalink=ru/events/foo/ The events is dynamic, it could be specials or packages. My dilemma is basically; I need to detect an empty link in order so I can feed a robots no index meta tag in the case of: page.php?permalink=events page.php?permalink=events/ page.php?permalink=ru/events/ page.php?permalink=ru/events I can't use a simple pattern such as [a-zA-Z]+\/?(.+)/ since it won't work on the i18n permalinks. What regex could I use which would detect this, using $_GET['permalink'] as the reference to the permalinks? And avoid false positives? Update: Empty link means there's no fragment after the "events/" part. These are empty: page.php?permalink=events page.php?permalink=events/ page.php?permalink=ru/events/ page.php?permalink=ru/events

  • Asp.Net MVC style routing in Django

    - by Andrew Hanson
    I've been programming in Asp.Net MVC for quite some time now and to expand a little bit beyond the .Net world I've recently began learning Python and Django. I am enjoying Django but one thing I am missing from Asp.Net MVC is the automatic routing from my urls to my controller actions. In Asp.Net MVC I can build much of my application using this single default route: routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = "" } // Parameter defaults ); In Django I've found myself adding an entry to urls.py for each view that I want to expose which leads to a lot more url patterns than I've become used to in Asp.Net MVC. Is there a way to create a single url pattern in Django that will handle "[Application]/view/[params]" in a way similar to Asp.Net MVC? Perhaps at the main web site level?

  • Libraries for developing NCPDP SCRIPT based systems (a standard for e-prescribing)

    - by Kaveh Shahbazian
    What are (based on experiences) best (commercial or open source) libraries for developing NCPDP-based systems? Background: NCPDP (National Council for Prescription Drug Programs) is a not-for-profit, ANSI-accredited, standards development organization. One of it's standards is the SCRIPT Standard for Electronic Prescribing, which allows PHARMACY, PRESCRIBER (i.e. Physician) and PAYERS (patient or more often insurer) communicate. So the SCRIPT standard is about data transmission. Problem: One step in implementing such systems is to develop models for data based on SCRIPT standard. These models should have utilities for serializing/deserializing to/from SCRIPT binary format and SCRIPT XML format (there are two distinct formats here; both must be supported). Here rises the problem (for me at least). To develop this subsystem for handling the model, implementing serializing and deserializing facilities and keep it uptodate with the SCRIPT standard specifications is a lot of work; it needs it's own team and team management issues (to support a standard implementation). So I am looking for a solution to this problem; to keep standard implementation out of the way and focusing on main problems. Thanks to all (Thankyou Freiheit for your hints!) Edit 2: Thanks to all for help! NCPDP (National Council for Prescription Drug Programs) is an standard for e-prescribing. It defines two formats for message transmission: binary and XML. Implementing XML is somehow easier because it is a standard format which in turn gives us more tooling options. The binary format has a very big specification and time-consuming to implement. I did not find an open source solution to work with. So I am looking for commercial alternatives. Edit 1: Please guide me; what's wrong with this question?

  • Optimizing a large iteration of PHP objects (EAV-based)

    - by Aron Rotteveel
    I am currently working on a project that utilizes the EAV model. This turns out to work quite well, but like many others I am now stumbling upon some performance issues. The data set in this particular case consists of aproximately 2500 entities, each with aprox. 150 attributes. Each entity and each attribute is represented by a PHP-object. Since most parts of the application only iterate through a filtered set of entities, we have not had very large issues yet. Now, however, I am working on an algorithm that requires iteration over the entire dataset, which causes a major impact on performance. This information is perhaps not very much to work with, but since this is an architectural problem, I am hoping for a architectural pattern to help me on the way as well. Each entity, including it's attributes takes up aprox. 500KB of memory.

  • Following PHP coding of Wisdom

    - by justjoe
    i read some wisdom like this : Programmers are encouraged to be careful when using by-reference variables since they can negatively affect the readability and maintainability of the code. i make my own solution, such as give suffix such as _ref in every by-reference variables. so, if i have a variable named as $files_in_root, then i will add suffix and changes it name into $files_in_root_ref. As far my knowledge goes, this is a good solution. So, here come the question Is there any best-practice on choosing suffix for by-reference variable in PHP coder world ? Or do you have any ? In general, how do we sustain readability and maintainability on PHP project with more then 3000 line of code ? I hope PHP coder world has unwritten aggrement for first question, cause it will help spot a pattern on any source code.

  • Parsing a DateTime String into Custom Date and Time Format String

    - by AMissico
    With .NET, I have "Thursday, April 10, 2008 1:30:00 PM" and I want "dddd, dd MMMM, yyyy h:m:s t", "6:09:01 PM" and want ""hh:mm:ss tt", "Fri 29 Aug" and want "ddd d MMM", and so on. It seems I should be able to use DateTimeFormatInfo in some way. I figured I can format the date with each pattern returned by GetAllDateTimePatterns, and when the original date string and the formated date string match then I have the format. Yet, I want to generate custom formats, not the standard formats. I want the format string. I do not want the date. I have both the DateTime value and the formatted string value for the date. I need <formatString> as in ToString(<formatString>).

  • Why use MVVM???

    - by LnDCobra
    Okay, I have been looking into MVVM pattern, and each time I have previously tried looking into it, I gave up for a number of reasons: Unnecessary Extra Long Winded Coding No apparent advantages for coders (no designers in my office. Currently only myself soon to be another coder) Not a lot of resources/documentation of good practices! (Or at least hard to find) Cannot think of a single scenario where this is advantageous. I'm about to give up on it yet again, and thought I'd ask to see if someone answer the reasons above. I honestly can't see an advantage of using this for a single/partner coding. Even in complex projects with 10's of windows. To me the DataSet is a good enough view and binding like in the answer by Brent following question
