• Delphi TerminateThread equivalent for Android

  - by Martin

  I have been discussing a problem on the Indy forums related to a thread that is not terminating correctly under Android. They have suggested that there may be an underlying problem with TThread for ARC. Because this problem is holding up the release of a product a work around would be to simply forcibly terminate the thread. I know this is not nice but in this case I cant think of a side effect from doing so. Its wrong but its better than a deadlocked app. Is there a way to forcibly terminate a thread under Android like TerminateThread does under windows? Martin

• C# equivalent of the C++ custom project Wizard

  - by gbjbaanb

  Hi., I have an existing wizard template created for VC++ from year back, ported to VS2008. It uses the custom wizard jscript/html templating system and DTE object. I've used this successfully for years, but now I want to create an entry for a standard C# project, I see there's no way to customise the C# project settings - the methods are for VC++ only. Is there something closely related to this for C# projects (or do I have to learn yet another way of creating a wizard for .net apps?)

• R equivalent of .first or .last sas operator

  - by Giorgio Spedicato

  Does anybody know what is the best R alternative to SAS first. or last. operators? I did find none. SAS has the FIRST. and LAST. automatic variables, which identify the first and last record amongst a group with the same value with a particular variable; so in the following dataset FIRST.model and LAST.model are defined: Model,SaleID,First.Model,Last.Model Explorer,1,1,0 Explorer,2,0,0 Explorer,3,0,0 Explorer,4,0,1 Civic,5,1,0 Civic,6,0,0 Civic,7,0,1

• Python equivalent of Java's compareTo()

  - by astay13

  I'm doing a project in Python (3.2) for which I need to compare user defined objects. I'm used to OOP in Java, where one would define a compareTo() method in the class that specifies the natural ordering of that class, as in the example below: public class Foo { int a, b; public Foo(int aa, int bb) { a = aa; b = bb; } public int compareTo(Foo that) { // return a negative number if this < that // return 0 if this == that // return a positive number if this > that if (this.a == that.a) return this.b - that.b; else return this.a - that.a; } } I'm fairly new to classes/objects in Python, so I'd like to know what is the "pythonic" way to define the natural ordering of a class?

• Perl equivalent to Java's "throws" clause

  - by Konerak

  Is there a way in Perl to declare that a method can throw an error (or die)? EDIT: What interests me the most is a way to get the compiler or IDE to tell me I have an unchecked exception somewhere in my code. I always loved how in Java, a method could handle an Exception and/or throw it. The method signature allows to put "throws MyException", so a good IDE/compiler would know that if you use said method somewhere in your code, you'd have to check for the Exception or declare your function to "throws" the Exception further. I'm unable to find something alike in Perl. A collegue of mine wrote a method which "dies" on incorrect input, but I forget to eval-if($@) it... offcourse the error was only discovered while a user was running the application. (offcourse I doubt if there is any existing IDE that could find these kind of things for Perl, but atleast perl -cw should be able to, no?)

• Bluimp file upload send data to the server on .fileupload

  - by MyName

  OK I've Googled...Googled and Googled again with no avail on how I can send data to the server like an ajax call's data option for the file upload: $('#file_upload').fileupload({ dataType: 'json', url: "@(Url.Action("UploadFiles", "ExcelUpload"))", // formData: function(form) { return [{ name: "dataTable", value : "@(Model)"}];}, progressall: function (e, data) { $(this).find('.progressbar').progressbar({ value: parseInt(data.loaded / data.total * 100, 10) }); }, done: function (e, data) { BadFile(e, data); } }); controller would look something like this: [HttpPost] public ContentResult UploadFiles(Mytype param1, MyType Param2) { .. } I want to do something similar to this: $.ajax({ url: "@(Url.Action("Action", "Controller"))", type: "post", data: { param1: value, param2: @(Model) } }); On the fileupload callback. Is this possible? How can I pass values to the ServerSide? Should I switch to a different uploader..? Please help me out! I need to resolve this as soon as possible.

• Netstat -ban (or -oan) equivalent in C#

  - by mztan

  I'd like to know if a particular process is using a given port, i.e. netstat -ban. I came across using IPGlobalProperties to get the list of active connections, but this doesn't seem to include process information. It would be nice if there exists some class in C# that lets me do this programmatically. Ideally, I wouldn't have to pipe the cmd shell Process output. Thanks in advance.

• Equivalent of libwww-perl in .NET or Java

  - by voidvector

  I have written a crawler in Perl awhile back and it was super simple giving the high-level capability of libwww-perl. It is so straight forward in fact, it can take the raw HTML response of one request, and create the next HTTP request for you from the FORMs on that page (as in it will parse the HTML for you). Does anyone know any library like this on .NET or Java? Selenium is out of question because it requires the browser to be open, which we cannot accommodate in our implementation)

• Why are there so many data centres in Texas?

  - by jklp

  I've been searching for online hosting recently and have noticed a high concentration of hosting providers in Texas. Just wondering why this is? It couldn't be possibly be because of temperature (I don't think Texas is a particularly cool place to be) or maybe power is cheaper in Texas vs the rest of the States? Or maybe it's just there are laws in place which give hosting providers tax breaks? Would be very interested to find out.

• What's the Ruby equivalent of Python's output[:-1]?

  - by Thierry Lam

  In Python, if I want to get the first n characters of a string minus the last character, I do: output = 'stackoverflow' print output[:-1] I can do the above in Ruby with: output = 'stackoverflow' output.reverse[1..output.length] Is there another way to perform this action in Ruby?

• Rails equivalent of respond_to |format| with a straight render

  - by brad

  I'm working with ActiveResource a lot so my service models are only using XML. Thus, I have no need for a respond_to block, I literally just render :xml => @model I can't however figure out how to render a 404 header using this. I've had to resort to respond_to, which I think adds a few unnecessary method calls. Here's what I'm using: respond_to do |format| if (record_found) render :xml => @some_record else format.xml{ head :not_found } end end but I just want something like render :xml => head :not_found which doesn't work. Can anyone tell me the proper syntax?

• Django equivalent for latest entry for each user

  - by paul-ogrady

  Hi, I'm surprised this question hasn't come up. Couldn't find much on the web. Using Entry.objects.latest('created_at') I can recover the latest entry for all Entry objects, but say if I want the latest entry for each user? This is something similar to an SQL latest record query. But how do I achieve this using the ORM? Here is my approach I'm wondering if it is the most efficient way to do what I want. First I perform a sub query: Objects are grouped by user and the Max (latest) created_by field is returned for each user (created_at__max) I then filter Entry objects based on the results in the subquery and get the required objects. Entry.objects.filter(created_at__in=Entry.objects.values('user').annotate(Max('created_at')).values_list('created_at__max')) or using a manager: class UsersLatest(models.Manager): def get_query_set(self): return Super(UsersLatest,self).get_query_set().filter(created_at__in=self.model.objects.values('user').annotate(Max('created_at')).values_list('created_at__max')) Is there a more efficient way? possibly without sub query? Thanks, Paul

• Accessing the Custom Object Return type from ojdbc6 JDBC Thin Drivers

  - by Andrew Harmel-Law

  I'm writing some JDBC code which calls a Oracle 11g PL/SQL procdedure which has a Custom Object return type. I can get the code to call the procedure, but how do I access the returned Custom Object to obtain it's contained values?. An example of my code calling the procedure is below: PLSQL Code: Procedure GetDataSummary (p_my_key IN KEYS.MY_KEY%TYPE, p_recordset OUT data_summary_tab, p_status OUT VARCHAR2); Java Code: String query = "begin manageroleviewdata.getdatasummary(?, ?, ?); end;"); CallableStatement stmt = conn.prepareCall(query); stmt.setInt(1, 83); stmt.registerOutParameter(2, OracleTypes.ARRAY, "DATA_SUMMARY_TAB"); stmt.registerOutParameter(3, OracleTypes.VARCHAR); stmt.execute(stmt); How do I get the result back fron this?

• Is there a Java equivalent to libevent?

  - by JoelPM

  I've written a high-throughput server that handles each request in its own thread. For requests coming in it is occasionally necessary to do RPCs to one or more back-ends. These back-end RPCs are handled by a separate queue and thread-pool, which provides some bounding on the number of threads created and the maximum number of connections to the back-end (it does some caching to reuse clients and save the overhead of constantly creating connections). Having done all this, though, I'm beginning to think an event-based architecture would be more efficient. In searching around I haven't found any equivalents to libevent for Java, but maybe I'm not looking in the right place? Mina-statemachine from Apache was the closest thing I found, but it looks more verbose than I need and there's no real release available. Any suggestions?

• Is yield break equivalent to returning Enumerable<T>.Empty from a method returning IEnumerable<T>

  - by Mike Two

  These two methods appear to behave the same to me public IEnumerable<string> GetNothing() { return Enumerable.Empty<string>(); } public IEnumerable<string> GetLessThanNothing() { yield break; } I've profiled each in test scenarios and I don't see a meaningful difference in speed, but the yield break version is slightly faster. Are there any reasons to use one over the other? Is one easier to read than the other? Is there a behavior difference that would matter to a caller?

• Is there a web application equivalent of Hypercard?

  - by Gabriel Cuvillier

  Recently, I found an interesting Wiki/CMS/Database hybrid called Wagn, where the most important unit of information is the 'Card'. That terminology immediately made me think of Hypercard. As expected, there is some "Hypercard-ness" in that application. Do you know of other web applications/frameworks with that "Hypercard-ness" thing, or if its successor still must be invented? Note: I insist on web applications because I already know the desktop ones.

• How to expose a Delphi set type via Soap

  - by Wouter van Nifterick

  I'm currently creating soap wrappers for some Delphi functions so that we can easily use them from PHP, C# and Delphi. I wonder what's the best way to expose sets. type TCountry = (countryUnknown,countryNL,countryD,countryB,countryS,countryFIN,countryF,countryE,countryP,countryPl,countryL); TCountrySet = set of TCountry; function GetValidCountrySet(const LicensePlate:string; const PossibleCountriesSet:TCountrySet):TCountrySet; I'm currently wrapping it like this for the soap server: type TCountryArray = array of TCountry; function TVehicleInfo.GetValidCountrySet(const LicensePlate:string; const PossibleCountriesSet:TCountryArray):TCountryArray; It works, but I need to write a lot of useless and ugly code to convert sets--arrays and arrays--sets. Is there an easier, more elegant, or more generic way to do this?

• How do I access data within this multidimensional array?

  - by dmanexe

  I have this array: $items_pool = Array ( [0] => Array ( [id] => 1 [quantity] => 1 ) [1] => Array ( [id] => 2 [quantity] => 1 ) [2] => Array ( [id] => 72 [quantity] => 6 ) [3] => Array ( [id] => 4 [quantity] => 1 ) [4] => Array ( [id] => 5 [quantity] => 1 ) [5] => Array ( [id] => 7 [quantity] => 1 ) [6] => Array ( [id] => 8 [quantity] => 1 ) [7] => Array ( [id] => 9 [quantity] => 1 ) [8] => Array ( [id] => 19 [quantity] => 1 ) [9] => Array ( [id] => 20 [quantity] => 1 ) [10] => Array ( [id] => 22 [quantity] => 1 ) [11] => Array ( [id] => 29 [quantity] => 0 ) ) I'm trying to loop through this array and perform a conditional based on $items_pool[][id]'s value. I want to then report back TRUE or NULL/FALSE, so I'm just testing the presence of to be specific.

• How to add system property equivalent to java -D in Ant

  - by Shervin

  Hi. I need to set java -Djava.library.path=/some/path and I want to do it when I am running my ant script, building my jar. I think I have to use <sysproperty key="java.library.path" value="/some/path"/> but it doesnt work. I cannot make the syntax work. The only thing I have Googled and found is sysproperty in conjunction with <java classname> but that doesnt make any sense to me. I am not sure if this is relevant, but I am using ant to create a ear and deploying this ear in JBoss.

• WPF, ShowGridLines equivalent for wrap panel

  - by user275587

  I need to display a 1 pixel wide border around all wrap panel cells, kinda like excel grid. Unfortunately the wrap panel does not implement the grid ShowGridLines property. I can't put a border inside every cell because adjacent cells will have a 2 pixel border instead of 1 pixel. Since the wrap panel arranges it's layout dynamically and does not expose it's properties I can't evaluate the correct value for a border inside a cell. Any workaround possible?
