  • Implement a simple class in your favorite language.

    - by Oscar Reyes
    I'm doing this to learn syntax of different programming languages. So, how would you defined the following class along with with it's operations in your favorite programming language? Image generated by http://yuml.me/ And a main method or equivalent to invoke it: For instance, for Java it would be: ... public static void main( String [] args ) { Fraction f = new Fraction(); f.numerator( 2 ); f.denominator( 5 ); f.print(); } ....

  • Need an Android Devloper with access to a Motorola Droid (Android 2.1)

    - by Rob Kent
    Apologies if this is the wrong place to ask this. I have an Android app on the market that has a reported problem only on Droid. I don't have access to the handset and cannot find anyone with one where I live. The problem I'm experiencing is partially explained at: http://stackoverflow.com/questions/2700983/problem-saving-file-on-motorola-droid-android-2-1. If you are an Android developer with a Droid, I'm happy to pay a reasonable fee if you'll debug the app for me. I'll send you the source. Please email me at [email protected]

  • I can't get mailto links to open the Mail app from Mobile Safari when using jQTouch. What could be w

    - by Mark B
    Hi all, I'm developing an iPhone web app using jQTouch, and it contains a simple mailto: link to a valid email address, which should launch the iPhone mail application when tapped—but it doesn't. If I visit a "normal" web page in Mobile Safari which contains the exact same link, and tap on it, I get the expected result: the mail app pops up with the correct email address in the To field. Here's the link HTML (with the address changed) just in case I'm going nuts and have made a stupid mistake, but it appears perfectly fine: <p><a href="mailto:[email protected]">[email protected]</a></p> Has anyone come across this when using jQTouch? Or can anyone at least suggest a way that I can debug this? At the moment when I tap the non-working link it flashes red (the active link state) and absolutely nothing else happens.

  • spidermonkey using JS_CallFunction for static function

    - by supersuraccoon
    JS_CallFunctionName can call a method of an object by name: JSObject* obj; JS_CallFunctionName(cx, obj, "doSomething", argc, vp, retVal); The code above works fine if the "doSomething" is a function declared in the prototype of the "obj". What I want to know is if there is a way to call a function that is a "class function". I tried: if(JS_HasProperty(getGlobalContext(), getGlobalObject(), "ClassToGet", &b)) { print("OK"); } and the output is "OK". But when tried: JS_GetProperty(getGlobalContext(), getGlobalObject(), "ClassToGet", &jsOwner); if (jsOwner != JSVAL_VOID) { } the jsOwner is a JSVAL_VOID. Maybe there is a function in SpiderMonkey can execute function in a JSClass ? Any suggestion will be appreciated, thanks :)

  • What are the typical reasons Javascript developed on Firefox fails on IE?

    - by karlthorwald
    I developed some javascript enhanced pages that run fine on recent Firefox and Safari. I missed to check in Internet Explorer, and now I find the pages don't work on IE 6 and 7 (so far). The scripts are somehow not executed, the pages show as if javascript wasn't there, although some javascript is executed. I am using own libraries with dom manipulation, from YUI 2 I use YUI-Loader and the XML-Http-Request, and on one page I use "psupload", which depends on JQuery. I am installing Microsoft Script Editor from Office XP and will now debug. I will also write specific tests now. What are the typical failing points of IE? What direction I can keep my eyes open. I found this page, which shows some differences: http://www.quirksmode.org/compatibility.html Can you from your experience name some typical things I should look for first? I will also ask more questions here for specific tasks later, but for now I am interested in your experience why IE usually fails on scripts that run fine in Firefox

  • Code jumps out of a jar and runs? What is causing this?

    - by Mike
    I am trying to get a sample program working with JUNG, a graphing tool in Java. I downloaded and referenced all the .jar files in eclipse so my project hierarchy looks like this: In Test.java I have the following code: public class Test { static public void main() { System.out.print("Hello"); }} For some reason though when I try to run it as a Java Application by right clicking on Jung test in the project hierarchy I am presented with a bunch of classes. My Test.java isn't on the list so if I just leave it as ** and press ok it starts running a program that is dynamically adding nodes and vertexes to a graph. I can't seem to figure out what code its actually executing. I know java but stuff like this with the jar files seems to be getting lost on me. Any ideas? Thanks

  • GWT Internet Explorer Problem

    - by bhargava
    Hi All, I am running into a problem which is quite a bit surprising.I have an GWT application,which i can run perfectly fine on Firefox,but the same GWT application does not open up in Internet Explorer. When using Firefox i use <set-property name="user.agent" value="gecko1_8"/> and when i want to run in Internet Explorer i change it to <set-property name="user.agent" value="ie8"/> and debug.This way i am sure that the problem i am having is not related to deferred binding. When using the Internet Explorer (IE 8) i cannot even get into the onModuleLoad() part of my application.It looks as if Internet Explorer has downloaded all its stuff ,but has nothing to display. Is there something that i am missing here Thanks Bhargava

  • Printing saved HTML to jsp keeps getting corrupted

    - by JWL
    I have a JAVA object where I save a HTML string value I call message. The saved data looks like the below, You have received a new <a href='' onclick='return popupRentalView('5282053859835904');'>Rental Request 5282053859835904</a>. Please view your open orders. But when printed to the JSP file and displayed at runtime using <%=pm.getMessage()%> or <%out.print(pm.getMessage());%> The actual html code comes out all messed up, You have received a new <a 5282053859835904');'="" onclick="return popupRentalView(" href="">Rental Request 5282053859835904</a> . Please view your open orders. Any thoughts on why the displayed string does not match the saved string? JAVA code for saving is note.setMessage("You have received a new <a href=\"\" onclick='return popupRentalView('" + requestId + "');'> Rental Request " + requestId + "</a>. Please view your open orders.");

  • Access Rules created by WSAT are not enforced

    - by rsteckly
    Hi, I'm trying to implement roles in my site. There are several projects in the solution, one of which is a web application. In that web application, I'm trying to use WSAT to create three roles. There are many folders for the application. I've used WSAT to define role based access rules for each folder. However, when I debug and navigate to those pages, they do not redirect to a login and show me the protected page. There are web.config files in each folder. Why would the system not enforce these rules? My web.config file has: I've tested the connections in WSAT and they work. Any ideas?

  • Silverlight datagrid don't show any data with anonymous query RIA services

    - by user289082
    Hi all! I have an anonymous linq query that I bind to a datagrid, when I debug it brings alright the data but it doesn't show in the datagrid, I suspect that the request to RIA services isn't completed before I bound it to the datagrid. I could use the LoadOperation<() Completed event. But it only works with Defined Entities so how can I do that? For reference here is the last post: http://stackoverflow.com/questions/2403903/linq-query-null-reference-exception Here is the query: var bPermisos = from b in ruc.Permisos where b.IdUsuario == SelCu.Id select new { Id=b.Id, IdUsuario=b.IdUsuario, IdPerfil=b.IdPerfil, Estatus=b.Estatus, Perfil=b.Cat_Perfil.Nombre, Sis=b.Cat_Perfil.Cat_Sistema.Nombre }; I'm a totally newbie sorry if is a very simple question. Thanks!!

  • Wordpress Taxonomy

    - by ninusik
    I am creating a Wordpress blog (no live link yet because it's still at a planning stage). I want to set up the following tag structure: Category 1: Services Tags: Web design, logo design, print design, etc etc. Category 2: Type of clients Tags: small businesses, large companies So each post will be tagged with one or more tags from Category 1, and one tag from Category 2. However, I heard that using more than one Category per post is a bad idea in terms of SEO? But then, how can I go about it? I don't want any SEO penalties, but I will need to somehow categorize each post using these 2 distinct categories. Should I create some custom taxonomies? That seems like an overkill to me. The solution is probably something rather simple but it just escapes me. I'm not very experienced with taxonomies so I'll appreciate any suggestions.

  • Force line-buffering of stdout when piping to tee

    - by houbysoft
    Usually, stdout is line-buffered. In other words, as long as your printf argument ends with a newline, you can expect the line to be printed instantly. This does not appear to hold when using a pipe to redirect to tee. I have a C++ program, a, that outputs strings, always \n-terminated, to stdout. When it is run by itself (./a), everything prints correctly and at the right time, as expected. However, if I pipe it to tee (./a | tee output.txt), it doesn't print anything until it quits, which defeats the purpose of using tee. I know that I could fix it by adding a fflush(stdout) after each printing operation in the C++ program. But is there a cleaner, easier way? Is there a command I can run, for example, that would force stdout to be line-buffered, even when using a pipe?

Its trying to link against a library of the same name as my executable for some reason when that project doesn't nor never existed and is not defined as a library to link against in my project files.

  • Python module seeing a full list as empty in another module

    - by Nick
    I'm working on a pygame project and have the main engine layed out. The problem is I hit a bug that I just can not seem to figure out. What happens is one module can't read a variable from another module. It's not that the variable can't be read, it just sees an empty list instead of what it really is. Instead of posting the entire source code I reproduced the bug in two small snippets that hopefully a skillful python-ist can interpret in his\her head. Code: main.py (This is the file that gets run) import screen screens = [] #A stack for all the game screens def current_screen(): #return a reference to the current screen return screens[-1] def play(): print'play called' current_screen().update() if __name__=='__main__': screens.append(screen.Screen()) play() screen.py import main class Screen: def __init__(self): print'screen made' def update(self): print main.screens #Should have a reference to itself in there Thanks!

  • Why do I get a "Day too big" error from Perl?

    - by azp74
    I have been helping someone debug some code where the error message was "Day too big". I know that this springs from localtime and the Y2038 bug (most google results appear to be people dealing with cookies expiring well into the future). We appear to have 'fixed' the problem by using time to get the current date. However, given that none of our original dates should have hit the 2038 issue I'm sceptical that we've actually fixed the problem ... Are there other instances that anyone knows of where one would hit "day too big"? OS is Solaris. Sample code - the actual code is quite large and the person I'm working with hasn't actually isolated the offending part (which is why I'm worried the 'fix' is not actually a fix). If I can put together something concise which reproduces the issue I will post!

  • 'int' object is not callable

    - by Oscar Reyes
    I'm trying to define a simply Fraction class And I'm getting this error: python fraction.py Traceback (most recent call last): File "fraction.py", line 20, in <module> f.numerator(2) TypeError: 'int' object is not callable The code follows: class Fraction(object): def __init__( self, n=0, d=0 ): self.numerator = n self.denominator = d def get_numerator(self): return self.numerator def get_denominator(self): return self.denominator def numerator(self, n): self.numerator = n def denominator( self, d ): self.denominator = d def prints( self ): print "%d/%d" %(self.numerator, self.denominator) if __name__ == "__main__": f = Fraction() f.numerator(2) f.denominator(5) f.prints() I thought it was because I had numerator(self) and numerator(self, n) but now I know Python doesn't have method overloading ( function overloading ) so I renamed to get_numerator but that's not the problems. What could it be?

  • How do I get the sums of the digits of a large number in Haskell?

    - by Tim
    I'm a C++ Programmer trying to teach myself Haskell and it's proving to be challenging grasping the basics of using functions as a type of loop. I have a large number, 50!, and I need to add the sum of its digits. It's a relatively easy loop in C++ but I want to learn how to do it in Haskell. I've read some introductory guides and am able to get 50! with sum50fac.hs:: fac 0 = 1 fac n = n * fac n - 1 x = fac 50 main = print x Unfortunately at this point I'm not entirely sure how to approach the problem. Is it possible to write a function that adds (mod) x 10 to a value and then calls the same function again on x / 10 until x / 10 is less than 10? If that's not possible how should I approach this problem? Thanks!

  • Drupal and Login Toboggan -- infinite redirect loop

    - by Ian Silber
    I'm getting a redirect loop when using Login Toboggan. It doesn't happen all of the time and I think I've narrowed it down to something with the session, specifically the active-tabs[last-active-href] value. Since it's intermittent, I was able to print out a session of a working copy and a non-working copy. Here are both: WORKS -- Array ( [active-tabs] = Array ( [last-active-href] = index ) ) toboggan/denied DOESN'T WORK -- Array ( [active-tabs] = Array ( [last-active-href] = user/register [user] = user/register ) [wantsEvents] = [wantsResources] = [wantsSupport] = ) toboggan/denied I've also noticed that if I comment out the following line the redirection loop stops (although no page loads): $return = menu_execute_active_handler('user/register'); Any ideas? I'm at my wits end.

  • java.util.Date.toString() is printing out wrong format

    The following code prints out "vmtDataOrig.creationdate=2012-11-03" VmtData vmtDataOrig = VmtDataDao.getInstance().loadVmt(1); System.out.println("vmtDataOrig.creationdate=" + vmtDataOrig.getCreationDate().toString()); Here is the definition of the creationDate field in the VmtData class: private Date creationDate = null; Here is the hibernate mapping of the creationDate field to the database table column: <property name="creationDate" column="CREATIONDATE" type="date"/> The CREATIONDATE column in the MySQL database table is of type "date", and for the record retrieved it has the value "2012-11-03". The Javadoc for the java.util.Date.toString() method says it is supposed to print the Date object in the form "dow mon dd hh:mm:ss zzz yyyy". Anyone know why it is printing it out in the form "yyyy-MM-dd"?
