• An elegant / simple way to check whether internet is available or not.

  - by Trainee4Life

  I did a quick search on how to check whether Internet is available or not. Most of them talked about making InterOp calls to wininet.dll. One of the answers pointed towards System.Net.NetworkInformation namespace. Exploring the namespace I found a class Ping which could be used to pinging to our servers from code, and checking whether server is available or not. What I want to ask is how this solution compares to other solutions? Ping soPing = new Ping(); var soPingReply = soPing.Send("www.stackoverflow.com"); if (soPingReply.Status != IPStatus.Success) { // SO not available }

• Deploy PHP website to client server without showing PHP files

  - by ColmF

  I asked a recent question regarding the use of readfile() for remotely executing PHP, but maybe I'd be better off setting out the problem to see if I'm thinking the wrong way about things, so here goes: I have a PHP website that requires users to login, includes lots of forms, database connections and makes use of $_SESSION variables to keep track of various things I have a potential client who would like to use the functionality of my website, but on their own server, controlled by them. They would probably want to restyle the website using content and CSS files local to their server, but that's a problem for later I don't want to show them my PHP code, since that's the value of what I'd be providing. I had thought to do this with calls to include() from the client's server to mine, which at least keeps variable scope intact, but many sites (and the PHP docs) seem to recommend readfile(), file_get_contents() or similar. Ideally I'd like to have a simple wrapper file on the client's server for each "real" one on my server. Any suggestions as to how I might accomplish what I need? Thanks, ColmF

• Measuring execution time of a call to system() in C++

  - by jm1234567890

  I have found some code on measuring execution time here http://www.dreamincode.net/forums/index.php?showtopic=24685 However, it does not seem to work for calls to system(). I imagine this is because the execution jumps out of the current process. clock_t begin=clock(); system(something); clock_t end=clock(); cout<<"Execution time: "<<diffclock(end,begin)<<" s."<<endl; Then double diffclock(clock_t clock1,clock_t clock2) { double diffticks=clock1-clock2; double diffms=(diffticks)/(CLOCKS_PER_SEC); return diffms; } However this always returns 0 seconds... Is there another method that will work? Also, this is in Linux. Thanks!

• render json data returned from mvc controller

  - by user1765862

  I'm having js function which calls mvc controller action method which return list of data as json. function FillCountryCities(countryId) { $.ajax({ type: 'GET', url: '/User/FillCityCombo', data: { countryId: countryId }, contentType: 'application/json', success: function (data) { alert(data[0].Name); } error: function () { alert('something bad happened'); } .... format of data which sent back from controller is Name (string) and Id (Guid) Now I just want to alert Name on success first item from collection. Double checked controller sends 20 records, so it should alert first from collection but I'm getting error something bad happened update: public JsonResult FillCityCombo(Guid countryId) { var cities = repository.GetData() .Where(x = x.Country.Id == countryId).ToList(); if (Request.IsAjaxRequest()) { return new JsonResult { Data = cities, JsonRequestBehavior = JsonRequestBehavior.AllowGet }; } else { return new JsonResult { Data = "Not Valid Request", JsonRequestBehavior = JsonRequestBehavior.AllowGet }; } }

• const member functions can call const member functions only?

  - by Abhi

  Hi all. Do const member functions call only const member functions? class Transmitter{ const static string msg; mutable int size; public: void xmit() const{ size = compute(); cout<<msg; } private: int compute() const{return 5;} }; string const Transmitter::msg = "beep"; int main(){ Transmitter t; t.xmit(); return EXIT_SUCCESS; } If i dont make compute() a const, then the compiler complains. Is it because since a const member function is not allowed to modify members, it wont allow any calls to non-consts since it would mean that the const member function would be 'indirectly' modifying the data members?

• Partially parse C++ for a domain-specific language

  - by PierreBdR

  I would like to create a domain specific language as an augmented-C++ language. I will need mostly two types of contructs: Top-level constructs for specialized types or declarations In-code constructs, i.e. to add primitives to make functions calls or idiom easier The language will be used for scientific computing purposes, and will ultimately be translated into plain C++. C++ has been chosen as it seems to offer a good compromise between: ease of use, efficiency and availability of a wide range of libraries. A previous attempt using flex and bison failed due to the complexity of the C++ syntax. The existing parser can still fail on some constructs. So we want to start over, but on better bases. Do you know about similar projects? And if you attempted to do so, what tools would you use? What would be the main pitfalls? Would you have recommendations in term of syntax?

• show() doesn't redraw anymore

  - by Abruzzo Forte e Gentile

  Hi All I am working in linux and I don't know why using python and matplotlib commands draws me only once the chart I want. The first time I call show() the plot is drawn, wihtout any problem, but not the second time and the following. I close the window showing the chart between the two calls. Do you know why and hot to fix it? Thanks AFG from numpy import * from pylab import * data = array( [ 1,2,3,4,5] ) plot(data) [<matplotlib.lines.Line2D object at 0x90c98ac>] show() # this call shows me a plot #..now I close the window... data = array( [ 1,2,3,4,5,6] ) plot(data) [<matplotlib.lines.Line2D object at 0x92dafec>] show() # this one doesn't shows me anything

• Echo html+php from database

  - by pg-robban

  I am working on a site which deals with a lot of texts in HTML, so recently I learned PHP and moved them into a MySQL database and echo the contents given a specific chapter and section. Now this works relatively fine, the HTML shows up properly. However, in some parts I have included PHP function calls, and these doesn't seem to be evaluated - rather, they get just inserted into the source code (and thus invisible for the page viewer), never doing anything. They did work when they were simple .html files. How can I solve this? For example, a text can look like this: <?php printChapterName(); ?> <p>Some text</p> ... <?php showImage($name, $alt-text); ?> ... This just shows the text on the page. Edit: The functions are echo:ing some HTML.

• Strange "cache" effect between client and server

  - by mark

  I use a Socket-based connection between Client and server with ObjectOutputStream. The objects serialized and exchanged have this structure: public class RichiestaSalvataggioArticolo implements Serializable { private ArticoloDati articolo; public RichiestaSalvataggioArticolo(ArticoloDati articolo) { this.articolo = articolo; } @Override public void ricevi(GestoreRichieste gestore) throws Exception { gestore.interpreta(this); } public ArticoloDati getArticolo() { return articolo; } } the issue is that when I try to exchange messages between C/S with incapsulated content very similar (ArticoloDati whom differ only in 2 fields out of 10), the Client sends an ArticoloDati, but the Server receives the previous one. Does the ObjectOutputStream implement some kind of cache or memory between the calls, that fails to recognize that my 2 objects are different because they are very similar?

• Is call to function object inlined?

  - by dehmann

  In the following code, Foo::add calls a function via a function object: struct Plus { inline int operator()(int x, int y) const { return x + y; } }; template<class Fct> struct Foo { Fct fct; Foo(Fct f) : fct(f) {} inline int add(int x, int y) { return fct(x,y); // same efficiency adding directly? } }; Is this the same efficiency as calling x+y directly in Foo::add? In other words, does the compiler typically directly replace fct(x,y) with the actual call, inlining the code, when compiling with optimizations enabled?

• read successive frames OpenCV using cvQueryframe

  - by AtharvaI

  Hi all I have a basic question in regards to cvQueryFrame() in OpenCV. I have the following code: IplImage *frame1,*frame2; frame1 = cvQueryFrame(capture); frame2 = cvQueryFrame(capture); Now my question is: if frame1 is a pointer to the first frame, is frame2 a pointer to the 2nd frame? So will the two cvQueryFrame() calls read successive frames? I thought I'd check myself first but the pointers frame1,frame2 seem to have the same hex value. :s I just need to capture two frames at a time and then need to process them. Thanks in advance

• Using App Engine to update a database in a app

  - by tyczj

  I have been reading about app engine but I still dont know what I can and cant do with it in a android application. Basically what I want to do is be able to create/manage a database in the cloud that the app can pull down and update the local database if needed. Creation and managing would be done outside of the app by me. I dont know much about all of this as I am just getting started with it but I already have an application made, I just want to add this feature to it. I have never written any sort of Web Service calls or anything either but I have used them to get data and such Can this be done? Any tutorials out there to help me out?

• java service could not be initialized (debugging help)

  - by vikasde

  I have a jar package that I wrote using netbeans. This package is called from other java file. The jar calls a webservice and is supposed to do something with it. Now everything works fine locally. I compiled the files and locally and uploaded them to the server and when I run it, I get the "Service could not be initialized".I am not sure how to debug this. I am pretty new to java. What is the best approach here to solve the issue?

• how can I reliably check that requests to my service file have come from my website?

  - by woot586

  I have a service.php class that I use to service AJAX calls from my website. To prevent other people accessing the service using PHP CURL I would normally check the request has come from mysite, and if they are not then just redirect to my home page e.g. if($_SERVER['HTTP_REFERER'] != "http://www.mysite.com"){ header('location: http://www.mysite.com'); exit; } I read in the PHP holy bible: http://www.php.net/manual/en/reserved.variables.server.php that "Not all user agents will set this, and some provide the ability to modify HTTP_REFERER as a feature. In short, it cannot really be trusted." So if this method is not reliable, my question is how can I reliably check that requests to my service file have come from my website? Thanks for any help you can provide!

• Reading programming tutorials while at work

  - by Teifion

  I work in a call centre and have been told by my manager that when there are no calls coming through they're happy for me to read stuff on the internet. There is a net filter in place but I can access SO from work which is always handy. I'm searching for articles that will make me a generally better programmer. I code in Python but combine it with Postgres and JS quite a lot if that helps. I'm currently reading Dive into python3 but I fear it won't last me much longer and would really like to expand my programming ability.

• imageview draw issue with asynctask

  - by alexb

  Have the following asynctask that i'm using to download some images. Works fine except for the very first image, which doesn't always appears unless I do something like move to the next image and then back again. public class DownloadImageTask extends AsyncTask { static ImageView _imageView=null; public DownloadImageTask(ImageView ctl){ _imageView=ctl; } protected void onPostExecute(Bitmap result) { _imageView.setImageBitmap(result); } ... } I thought this might be an issue with updating the UI on a background thread, so I reworked this using an abstract class that invokes a method on the UI thread that calls .setImageBitmap() but I still get the same behaviour - works fine for all images except the first, unless I move to the next image and back again. Is there a way to force a redraw on the imageview after i set the image?

• Connecting to TFS via ASP.NET, jQuery and Phonegap

  - by Tony D.

  I want to develop a mobile application that would allow the user the ability to run a suite of automated test cases housed in TFS. This is something I thought of this morning so it's all still very preliminary. But I'm curious as to what would be the best route for something like this? Or if it's even possible? Because the mobile devices from the users will vary from iphones to droids, I would probably want to incorporate something like Phonegap for it's cross platform capabilities. My initial thought was to develop in ASP.net/C# (which would be stored on a remote server), and have jQuery make calls to that server. Not sure if that would be the most appropriate way of handling this. I'm not too familiar with JSON but I have seen it as a suggestion on various sites to handle the returned data. Any thoughts or suggestions are appreciated. Thanks.

• .net MVC, dealing with json and Areas

  - by JoseMarmolejos

  When not using areas dealing with the url for the JsonResults from the clientside is not much of a pain, usually you can get away with hardcoding the url into your json calls and get away with it. Problem arises when you have different areas and you don't want to update all your links when you move a controller (and its views) from one area to the other. I'm not very satisfied with the way I'm handling this scenario by having this chunk of code inside every view: <script type="text/javascript"> var ControllerActions = { JsonSearch: '<%= Url.Action("JsonSearch") %>/', JsonDelete: '<%= Url.Action("JsonDelete") %>/', Edit: '<%= Url.Action("Edit") %>/', Delete: '<%= Url.Action("Delete") %>/' } </script> While it does work no matter where I place the views/controllers I wonder if there's a more elegant to do this.

• How to add on to an existing onclick event?

  - by Corey Sarnia

  I'm currently writing a Greasemonkey script for a page, so I can't modify the script myself. There is a form submit button on the page. When you click this button, it executes some fancy AJAX calls and such to update the page and do serverside things. What I'm trying to is basically set a "lastClick" value when the button is clicked. I want to add the code GM_setValue("lastClicked", (new Date()).getTime().toString()) to store the last time the button was clicked (for future uses of the script, it will actually do something with this date). How exactly can I accomplish this?

• How to persist every new entity?

  - by simpatico

  I expect every instantiated entity to correspond to a tuple (& co) in the database. In the examples I see around, one always instantiates the entity (via a constructor) and then calls persist with that entity. I find this error-prone, and was wondering if it wasn't possible to have every instantiated entity automatically managed/persisted/reflected to the database (at least intended to). This also seems to prevent me from persisting instance variable entities. I.e. I've an entity which instantiates another (entities it has an association with) in its constructor.

• Method overloading in groovy

  - by slojo

  I am trying to take advantage of the convenience of groovy's scripting syntax to assign properties, but having trouble with a specific case. I must be missing something simple here. I define class A, B, C as so: class A { A() { println "Constructed class A!" } } class B { B() { println "Constructed class B!" } } class C { private member C() { println "Constructed class C!" } def setMember(A a) { println "Called setMember(A)!" member = a } def setMember(B b) { println "Called setMember(B)!" member = b } } And then try the following calls in a script: c = new C() c.setMember(new A()) // works c.member = new A() // works c.setMember(new B()) // works c.member = new B() // doesn't work! The last assignment results in an error: 'Cannot cast object of class B to class A". Why doesn't it call the proper setMember method for class B like it does for class A?

• Global variable in a recursive function how to keep it at zero?

  - by Grammin

  So if I have a recursive function with a global variable var_: int var_; void foo() { if(var_ == 3) return; else var_++; foo(); } and then I have a function that calls foo() so: void bar() { foo(); return; } what is the best way to set var_ =0 everytime foo is called thats not from within itself. I know I could just do: void bar() { var_ =0; foo(); return; } but I'm using the recursive function a lot and I don't want to call foo and forget to set var_=0 at a later date. Does anyone have any suggestions on how to solve this? Thanks, Josh

• Routing Skype call to another Voip company

  - by Anarchist

  Hello, As my project to do over this summer I would like to create a program that answers a Skype call using the Skype API and allows a user to connect to another VOIP provider (through SIP) and make calls by dialling through the client callers Skype application. I understand that the Skype API allows me to answer and receive keypad input, but I'm stuck on actually sending the sound of the call to a SIP client. Is there an API/library that would allow me to take the Skype receiving audio as input in the SIP client? Is this even possible? I'm not tied to a language but I had planned on using Python. Thanks.

• Can I include both Apache Axis 1 and 2 libraries in the same project?

  - by ian_scho_es

  If it sounds like a ridiculous idea then it is. The client only wants to have to install one project on their server. Our web service will be bridging between mobile phones and various SOAP services made in .NET, Apache Axis 1 and 2, which rely on standards to transfer files such as MTOM and DIME. I am looking for an 'architecture' trick, such as develop the Axis 1 calls in a separate project and compile as a jar, to then pass it into the Axis 2 project.... Hmmm. Anything rather than having to download the source code for Axis 1 & 2 and compile them using the same xml libraries, etc. "It can't be done" is an acceptable answer. Thanks!

• How to show/hide UIImageView when I want.

  - by Madness64

  I'm having a little problem with an iPhone app I'm currently developing. When the user touch a button, it calls an IBAction named refreshQuestion, which is supposed to show an image hover the screen to ask the user to wait a moment, then it has to call another function, and finally it has to hide the image. The problem is that the image won't appear. As well as the network activity indicator. Any help? Here is the code : - (IBAction)refreshQuestion:(id)sender{ pleaseWait.hidden = NO; [UIApplication sharedApplication].networkActivityIndicatorVisible = YES; [self loadData]; pleaseWait.hidden = YES; [UIApplication sharedApplication].networkActivityIndicatorVisible = NO; }
