• Online compilers/runtime for Java, C++, Python and ObjC?

  - by Nocturne

  Does anyone know of a good online compiler/runtime (for C++, Java, Python, ObjC etc.) that I can access on the web? What I'm looking for is something that would allow me to type in a program in a web form and to run the program and see the results online. (Let's not get into the why for now. Suffice it to say for the moment that I don't always have access to a compiler/runtime, and firing up an IDE is just overkill for testing out some code snippets) I know of codepad.org -- but I'm looking for something better.

• didSelectRowAtIndexPath being called after viewDidLoad of the called view

  - by Serguei Fedorov

  I am trying to pass variables over to the new view. I have the following code: appDelegate *dataCenter = (AppDelegate*)[[UIApplication sharedApplication] delegate]; dataCenter.myVariable = [array objectAtIndex:indexPath.row]; in the didSelectRowAtIndexPath of the calling view. However, the issue that I have is that this variable is empty in the vewDidLoad function of the next view, simply because it fired off BEFORE the didSelectRowAtIndexPath of the calling view. I am using storyboard to link the views together. Both are UITableView. If I hit back and then reselect the table element it is then set, granted that by the time I hit back and then selected again, the variable got set. Is there any way to for the order of execution? I really don't want to do UI view switching on the back end. Any help is greatly appreciated!

• Google Play: how dev can give (already purchased) app to customer as a gift?

  - by Tertium

  Yes, SO, I know, it's not a "programmer's" question:) But customers sometimes help us (devs) with our code, so we (devs) shold be grateful. I think answer to my question will be useful for all fellow android devs. User has purchased my app. Refund period (15min) is over of course. Now I'd like to return money to him as a gift, because he helped me in testing a little. If I refund the entire order in Checkout-Orders will user keep my app 'purchased'? I mean will he be able to uninstall and install it again from GooglePlay-MyApps and will app be marked "purchased"? Will Google LVL accept him to run the app? I've done such refunds before, but then they called it "Android Market", and refund was 12h, and there were no LVL. Maybe somebody know another way to make a small gift using Google Play?

• Where are good examples of Web applications built for skilled and intense use?

  - by ProfK

  I have spent most of my development career writing backend code, or front-end apps for used as daily business tools, by at least semi-skilled staff, e.g. order-tracking, sales capture, etc. That those I helped build peformed their tasks well is comfort enough, but I am still seeking excellence in the building of these kind of apps, versus the more trendy emphasis on slow and sensual interpersonal relationships with the UI. Can anyone recommend reading on this type of application (LOB?) on the web today? Any available examples to study?

• PHP+MYSQL Server Config

  - by Matias

  Hi guys, I am parsing an XML file with PHP and inserting the rows in a MYSQL database. I am using PHP simplexml_load_files to load the XML and a foreach to loop through the array and insert the rows into my database. It works perfectly fine with small files i am testing, but it comes to reality I need to parse a large 500mb XML file and nothing happens. I was wondering what was the right Php.ini config for this case ? I have a VPS Linux Cent OS, with 256 mb of dedicated Memory and MYSQL 5.0.5. I have also set php memory_limit = 256M (maximum of my server) Any suggestions, similar experiences will be greatly appreciated Thanks

• Hosting Private Git repos on my own server?

  - by Stoic

  Hey, I am looking for a way to host private git repos on my own server. I am using Github for Open source projects of mine, but I would prefer to use my own server for storing private git repos. Can someone suggest me on which script should I be using for this purpose. Trac is not what I am looking for, though. I want something that is, preferably PHP based solution (just optional) and esp. something that has an easier UI. Any help is appreciated here.

• Hudson's FindBugs plugin reports line number "-1" for bugs. Ideas?

  - by John B.

  Greetings, I have a simple test project set up in Hudson and the project's build process (a batch file) generates a findbugs.xml file. This is processed by Hudson's FindBugs plugin but it shows the line number of the bugs as "-1" instead of their actual line number. A coworker suggested I enable debug info for the compiler. I used the -g "Generate all debugging info" option for javac but nothing seemed to change. My build command is: javac -g -classpath C:\testWebApp1\src -d C:\testWebApp1\build C:\testWebApp1\src\*.java The only other thing in the build.bat file is a call to the FindBug tool (text UI). Here is what the FindBugs Plugin says about the first bug: File: GenerateHellos.java, Line: -1, Type: UUF_UNUSED_FIELD, Priority: Normal, Category: PERFORMANCE Any ideas? Thanks a ton!

• Mock Objects properties not changing

  - by frictionlesspulley

  I am new to using Mock test in .Net. I am testing out a financial transaction which is of the following nature: int amt =20; //sets all the props and func and returns a FinaceAccount. //Note I did not SetUp the amt of the account. var account =GetFinanceAccount() //service layer to be tested _financeService.tranx(account,amt); //checks if the amt was added to the account.amt //here the amt comes out same as that set in GetFinanceAccount. Assert.AreEqual(account.amt ,amt) I know that the function tranx works correctly but there is an issue with the test. Are there any GOOD reference material on Mocking in .Net

• How to write a program that mimics Fiddler by using tcpdump or from scratch?

  - by ????

  When Fiddler is not on Mac OS X or Ubuntu, and if we don't install/use Wireshark or any other more heavy duty tools, what is a way to use tcpdump so that 1) It can print out GET /foo/bar HTTP/1.1 [request content in RAW text] [response content in RAW text] POST /foo/... HTTP/1.1 this should be able to be done by tcpdump or by using tcpdump in a short shell script or Ruby / Python / Perl script. 2) Actually, it can be neat if a script can output HTML, with GET /foo/bar HTTP/1.1 POST /foo/... HTTP/1.1 on the page, for any browser to display, and then when clicked on any of those lines, it will expand to show the RAW content like (1) above does. Click again and it will hide the details. The expansion UI can be done using jQuery or any JS library. The script may be short... possibly less than 20 lines? Does anybody know how to do it either for (1) or (2)?

• Rails- MiniMagick commands not working

  - by digitalWestie

  I'm running windows xp and I've got MiniMagick and ImageMagick installed (latest versions). I'm now using the console to test out that everything works. Using the ms command prompt image magick works no problem. I'm testing this by using the identify command. Now, when I try to use MiniMagick from the console by entering image = MiniMagick::Image.new('image.jpg') It returns MiniMagickError, "ImageMagick command ("identify \"input.jpg\"") failed: {:status_code = #"'identify' is not recognized as an internal or external command,\noperable program or batch file.\n"} Can anybody help?

• HTML5 video element non-seekable when using Django development server

  - by Ory Band

  Hey everyone. I've got a Django app serving a webpage with an HTML5 element. There's a wierd "feature", turning the video element to be non-seekable: video.seekable returns a timeRanges object with length=0, whereas it should be length=1. This means I can't edit the video. JavaScript can't do anything either. The thing is, when I upload the problematic webpage, statically - no Django, just plain HTML/JS/CSS - to my website for testing, it works fine - length=1. However, if I try to serve the same static page on my Django dev server still gives the same problem. I am using Django's static serving for dev/debug purposes - Do you have any idea what is causing this, or how can I fix it? Thanks.

• Apply CSS class to invalid controls on web form

  - by user137639

  I need to apply a css class to invalid controls on a web form. I'd like to make it a resusable class. This is what I have so far: public class Validation { public static void ApplyInvalidClass(Page page, string className) { foreach (System.Web.UI.WebControls.BaseValidator bv in page.Validators) { if (!bv.IsValid) { Control ctrl = page.FindControl(bv.ControlToValidate); if (ctrl != null) { if (ctrl is TextBox) { TextBox txt = ctrl as TextBox; txt.CssClass = "invalid"; } if (ctrl is DropDownList) { DropDownList ddl = ctrl as DropDownList; ddl.CssClass = "invalid"; } if (ctrl is CheckBox) { CheckBox cb = ctrl as CheckBox; cb.CssClass = "invalid"; } if (ctrl is HtmlGenericControl) { HtmlGenericControl html = ctrl as HtmlGenericControl; html.Attributes.Add("class", className); } } } } } } The problem is what I call this on a .Net user control, I guess because I'm passing in Page, page.FindControl(bv.ControlToValidate) is always null. Is there a better way to do this?

• Aptana Studio is opening but not ever closing a python.exe process

  - by SC Ghost

  I am developing a small testing website using Django 1.2 in Aptana Studio build 2.0.4.1268158907. I have a Django project that I test by running the command "runserver 8001" on my project. This command runs the project on a small server that comes with Django. However the problem arises that every time I run this command Aptana opens two instances of the process "python.exe". Upon terminating the command only one of these instances is ended. The other process continues to run and use memory. My server is not online, and the process doesn't seem to do anything that I can find. This happens every time i run the runserver command on my project and therefore more and more python.exe instances will open up through my development period. Any help discovering either the purpose of this extra python.exe or a way to prevent it from opening would be much appreciated.

• WPF Custom Navigation Buttons and calling one page from another

  - by Jeff

  I have a window which contains a Frame which references a 'home' page that has buttons on it. When a button is clicked I want another page to show depending on which button was pressed. I attempted to use NavigationService.Navigate('mynextpage.xaml') and that works however, I want to use a customized navigation panel. I call this.ShowsNavigationUI = false; on my 'home' page but the bar still shows. Is there a way to accomplish what I am trying to do? My page with the frame is a window so I do not know how to disable the Navigation bar there where I guess it is coming from. Further testing shows that the ShowsNavigationUI property is false yet the nav bar shows itself in the parent window once there is a second page to go to (showing the 'home' page in the history. TIA

• In Selenium IDE, can I store an element to use in subsequent asserts?

  - by Colin Fine

  I've just started using Selenium-IDE (not looked at selenium-RC yet: if somebody tells me that that is the answer to my question I'll look at it) One of the operations I'm testing generates some output in a table in the next HTML page, but the order of the rows is not predictable. I can obviously use 'assertTextPresent', but I want to do a bit more, and check that various bits of text are in the same row. What I would like to be able to do is to identify a tr by some content, and then use that tr in subsequent asserts; something like storeExpression //table[@id='TABLE_6']/td[.='case_1']/.. row assertText ${row} 'Some text' assertText ${row} 'Some other text' to check that 'Some text' and 'Some other text' occur in the same table row as 'case_1'. I haven't got this to work so far, and I'm not sure whether it is possible, or what syntax to use if it is. Has anybody managed to do this?

• How does the WP7 Pivot control dynamically load pivot items?

  - by mztan

  IIRC, the Pivot control only loads a child PivotItem if it is the currently shown child. I would then guess that the previously seen child is also somehow unloaded, presumably still stored in memory, but hidden from the UI. What I'm wondering is, how does the Pivot control dynamically load/unload a child control, and can that behavior be imitated within a custom UserControl? As for unloading, is it as simple as collapsing the previous child's visibility, or is something trickier going on? That is to say, supposing I use my own UserControl like: <my:CustomUserControl> <TextBlock x:Name="_textBlock" Text="wait for it ..." /> </my:CustomUserControl> Normally, the child TextBlock is instantiated when the surrounding PhoneApplicationPage is instantiated, via InitializeComponent and all that. Is there any way to postpone this behavior and load the child programmatically?

• Create link to Sitecore Item

  - by Zooking

  I know I have done this before but I can't seem to remember where or how. I want to create a link to an Item in Sitecore. This code: Sitecore.Data.Items.Item itm = Sitecore.Context.Database.GetItem(someID); return itm.Paths.Path.ToString(); Produces the following string: http://localhost/sitecore/content/Home/Item1/Item11/thisItem I would like to have this string instead: http://localhost/Item1/Item11/thisItem.aspx What is the correct way to get the path to the item? In this case I can't use a normal Sitecore link: Sitecore.Web.UI.WebControls.Link

• GWT HTMLTable colaspan feature

  - by Sanjay

  Hello all I am using HTMLTable of import com.google.gwt.user.client.ui.HTMLTable I instantiated it like below: HTMLTable table = new Grid(rows, col); Number of rows and columns are decided by the user input. Now I want to used colspan for the specific rows of the table. One way to this is apply css to the that specific row.But problem with this is that Number of column to span are decided by the user input, i.e It may vary every time. So by using css it is something like making it static. So I want to know the way through which I can do colspan on the rows of the table. and Number of column to span is different every time. Thanks in advance

• What non-standard behaviour features does Gmail exhibit, when it is programmatically used as a POP3 server?

  - by Mike Green

  I am trying to prepare a complete list of behaviour that Gmail POP3 exhibits, that you wouldn’t expect to generally find in a POP3 server. For example, Gmail appears to ignore the DELE (delete) command from a POP3 client. Instead, it implements its own delete and archive strategy. The purpose of preparing a list is to avoid developers testing a POP3 client against the Gmail POP3 server and then assuming that all POP3 servers behave in the same way. Can anyone provide a more complete list of non-standard behaviour?

• Why and How to avoid Event Handler memory leaks ?

  - by gillyb

  Hey There, I just came to realize, by reading some questions and answers on StackOverflow, that adding event handlers using += in C# (or i guess, other .net languages) can cause common memory leaks... I have used event handlers like this in the past many times, and never realized that they can cause, or have caused, memory leaks in my applications. How does this work (meaning, why does this actually cause a memory leak) ? How can I fix this problem ? Is using -= to the same event handler enough ? Are there common design patterns or best practices for handling situations like this ? Example : How am I supposed to handle an application that has many different threads, using many different event handlers to raise several events on the UI ? Are there any good and simple ways to monitor this efficiently in an already built big application ? Thanks in advance!

• Advice on creating simple web service

  - by London

  Hi all, I want to build simple SOAP web service. So far I've only worked with existing SOAP/Rest services. And now I'd like to create my own, simple one for starters. For example create simple hello + string web service where I provide the string in request from SOAP ui or similar tool. I have Jboss server installed already, what is the "simplest" possible way to achieve this? I realize I need interface, interfaceImpl, and a wsdl file(generated possibly). Does anyone have some useful advice for me ? thank you
