• Start PyGTK cellrenderer edit from code

  - by mkotechno

  I have a treeview with an editable CellRendererText: self.renderer = gtk.CellRendererText() self.renderer.set_property('editable', True) But now I need to launch the edition from code instead from user, this is to focus the user attention in the fact he just created a new row and needs to be named. I tried this but does not work: self.renderer.start_editing( gtk.gdk.Event(gtk.gdk.NOTHING), self.treeview, str(index), gtk.gdk.Rectangle(), gtk.gdk.Rectangle(), 0) Neither does not throw errors, but the documentation about for what is each argument is not clear, in fact I really don't know if start_editing method is for this. All suggestions are welcome, thanks.

• Prototype's Ajax.Request not working in Chrome

  - by Jason

  I am just doing a simple Ajax.Request call using the newest version of Prototype. It works fine in Firefox, Internet Explorer, and even Safari... but not in Chrome. Here is my code... alert(url); new Ajax.Request(url, { method: 'get', onSuccess: function(transport) { alert('test'); } }); It pops up he URL alert but the test alert never comes up. Like I said it does in every other browser. I am not getting any javascript errors and I have used Firebug. I did a console.log on each event and it gets to the onLoading stage of Ajax.Request but never onLoaded. Very confused... ?

• Passing data between states PHP

  - by esryl

  So I am using Limonade PHP which has a RESTful design which emulates PUT, POST, DELETE routes for create, update, delete. I am trying to develop some form validation which is going well. The major problem I am facing though is how to return my filtered data (which has failed validation) back to repopulate the create or edit form. How would this be done? I currently have for creating a page: /admin/page/new -> GET function /admin/page -> POST function + validate + pass, update db + fail, add errors to flash, redirect to /admin/page/mew It all falls down as I do not know how to populate the /admin/page/new with the invalid, but filtered data.

• UINavigationController Right button

  I am unable to set any property of parentController (which is always a UINavigationController in my case) from child views. e.g. I want to add a button on the navigation bar using following code: UINavigationController* parentController = (UINavigationController)self.parentViewController; UIBarButtonItem *addButton = [[[UIBarButtonItem alloc] initWithTitle:@"Something" style:UIBarButtonItemStyleBordered target:self action:@selector(doSomething)] autorelease]; [_parentController.navigationItem setRightBarButtonItem:addButton animated:YES]; This code runs perfectly without errors but I can't see any button added to the navigation bar. Thanks in advance.

• How do I specify MSBuild to execute command-line calls in ascii not unicode

• How to use @PersistentCapable annotation in Scala 2.8

  - by Gero

  Hi, I'm switching from Scala 2.7.7 to Scala 2.8.0RC3 and now a few of my classes don't compile anymore. The problem is in the @PersistentCapable annotation: import javax.jdo.annotations._ import java.util.Date @PersistenceCapable{identityType=IdentityType.APPLICATION} class Counter(dt: Date, cName: String, vl: int) { <.. snip ..> } This code results in the following compilation errors: [ERROR] /Users/gero/prive/kiva/kivanotify-gae/src/main/scala/net/vermaas/kivanotify/model/LoanProcessed.scala:7: error: expected start of definition [INFO] @PersistenceCapable{val identityType = IdentityType.APPLICATION} I already tried a couple of variations, did some Googling but without luck. Any ideas on how I can use the @PersistentCapable annotation with Scala 2.8.0 RC3? Thanks, Gero

• Problem with signals and slots

  - by Jen

  I am creating a class with custom slots in Qt: class CustomEdit : public QTextEdit { Q_OBJECT public: CustomEdit(QWidget* parent); public slots: void onTextChanged (); }; However, I'm getting thise linker error: undefined reference to 'vtable for CustomEdit' The documentation says: if you get compiler errors along the lines of "undefined reference to vtable for LcdNumber", you have probably forgotten to run the moc or to include the moc output in the link command. ... but it is not obvious what that means. Is there something I need to add to my class, or to the .pro file?

• System.WIndows.Application static members are thread safe?

  - by Lirik

  The Application static members are supposed to be thread safe: The public static (Shared in Visual Basic) members of this type are thread safe. In addition, the FindResource and TryFindResource methods and the Properties and Resources properties are thread safe.1 How much can we trust that statement in a multithreaded environment when calling static member methods of System.Windows.Application? Update: It's all in reference to this question: http://stackoverflow.com/questions/2463822/threading-errors-with-application-loadcomponent-key-already-exists/2463866#2463866 I never thought I'd see a real bug in the library, but this must be the day for me... that question seems to show a genuine bug. Usually it's "user error," but this doesn't seem to be the case.

• Cannot create class diagram for simple dll class in Visual Studio 2010

  - by xenn_33

  Hi, It seems that there is a really annoying issue in Class Diagram designer in VS (my version is 2010 Ultimate, but the issue is also observed in VS 2008). When I'm trying to create a class diagram for particular simple class from DLL I'm getting the following error: "Some of the selected type(s) cannot be added to the class diagram. Check the code for errors and ensure that all required assemblies ... blah-blah-blah" My code doesn't contain any error. I have multiple class and interface definitions in one separate .cs file, but these classes are really simple - even no calls to unmanaged/interop. Any solution for this?

• What's the best way to detect web applications attacks ?

  - by paulgreg

  What is the best way to survey and detect bad users behavior or attacks like deny of services or exploits on my web app ? I know server's statistics (like Awstats) are very useful for that kind of purpose, specially to see 3XX, 4XX and 5XX errors (here's an Awstats example page) which are often bots or bad intentioned users that try well-known bad or malformed URLs. Is there others (and betters) ways to analyze and detect that kind of attack tentative ? Note : I'm speaking about URL based attacks, not attacks on server's component (like database or TCP/IP).

• Unkillable console windows

  - by rep_movsd

  I'm developing an OpenGL based 2d simulation with GLUT under Visual C++ 2008, sometimes when I have an assert() or unhandled exception and break into the debugger, the GLUT display window closes, but the console window remains open.They just cant be killed!!! They do not show up with Task manager, Process Explorer or any other tool, I cannot find the window handle using the Spy++ tool either. Worst thing is they prevent my system (Windows XP) from shutting down, I have to manually poweroff (and of course I have to run chkdsk on my drives and invariably it finds and fixes minor errors after bad shutdowns) Has anyone come across such an issue?

• How do you diagnose a 500 error on Heroku when there is no error message in the logs?

  - by lala

  I have a Rails app on Heroku that is serving 500 errors at random intervals. Web pages will display "Internal server error" in plain text, instead of the usual "We're sorry. Something went wrong." page. When I refresh the page, it works fine. The logs don't show me an error message, just » 14:20:34.107 2013-10-11 12:20:33.763690+00:00 heroku router - - at=info method=HEAD path=/ host=www.mydomain.com fwd="184.73.237.85/ec2-184-73-237-85.compute-1.amazonaws.com" dyno=web.1 connect=1ms service=63ms status=200 bytes=0 » 14:21:03.957 2013-10-11 12:21:03.561867+00:00 heroku router - - at=info method=GET path=/ host=www.mydomain.com fwd="50.112.95.211/ec2-50-112-95-211.us-west-2.compute.amazonaws.com" dyno=web.1 connect=0ms service=1ms status=500 bytes=21 Support has told me to look at request queuing in New Relic, but New Relic only shows a big red mark saying the server is down (even though the site works fine when refreshed). With no error messages, I'm at a loss for how to diagnose this issue.

• Run groovy script from within gradle

  - by macattack

  What's the best way to create a gradle task, which runs a groovy script? I realize that gradle build files are groovy, so I would think it would be possible to do something like this: task run << { Script app = new GroovyShell().parse(new File("examples/foo.groovy")) // or replace .parse() w/ a .evalulate()? app.run() } I get all kinds of whacky errors when I try this if bar.groovy is using @Grab annotations or even doing simple imports. I want to create a gradle task to handle this, so that I can hopefully reuse the classpath definition. Would it be better to move the examples directory into the src directory somewhere? What's a best practice?
