• autoscrolling for UIScrollView

  - by thndrkiss

  Hi, I used the setContentOffset method to scroll to a particular point automatically without user interaction. [menuScrollView setContentOffset:CGPointMake(600.0,0) animated:YES] but when i try to call the same method in a looping fashion inorder to slow down the speed of scrolling the scrolling never happens for (int i = 1; i<=30; i++) { [menuScrollView setContentOffset:CGPointMake(600.0-i*10,0.0) animated:YES]; NSLog(@"%f",600.0-i*10); } During the above piece of code the scrolling of UIScrollview happens only once (1st iteration( and it does not scroll for remaining 29 interations. What is the problem here ?

• How do I return an Array from grails / jdo to Flex

  - by mswallace

  this seems really simple but I haven't gotten this to work. I am building my app with grails on google app engine. This pretty much requires you to use JDO. I am making an HTTP call from flex to my app. The action that I am calling on the grails end looks like so def returnShowsByDate = { def query = persistenceManager.newQuery( Show ) def showInstanceList = query.execute() return (List<Show>) showInstanceList } I have tried just returning "hello from grails" and that works just fine. I have alos tried the following return showInstanceList the JDO docs say the query.execute() returns a collection. Why I cant just return that to Flex I have no clue. Any thoughts?

• What is a proper way to pass a parameter to Set-Alias in powershell?

  - by Nick Gorbikoff

  Hello. A little background: I use PowerShell on windows xp at work and I set a bunch of useful shortcuts in Microsoft.PowerShell_profile.ps1 in My Documents, trying to emulate Mac environment inspired by Ryan Bates's shortcuts I have things like: Set-Alias rsc Rails-Console function Rails-Console {Invoke-Expression "ruby script/console"} Which works just fine when in command prompt I say: rsc #it calls the proper command However this doesn't work properly Set-Alias rsg Rails-Generate function Rails-Generate {Invoke-Expression "ruby script/generate"} So when I do : rsg model User which is supposed to call ruby script/generate model User all it calls is ruby script/generate #Dumping my params So how would I properly modify my functions to take params I send to functions? Thank you!!

• NetBeans behaves differently if project is run via "Run Project" or build.xml>run

  - by Rogach

  I slightly modified the build-impl.xml file of my NetBeans project. (Specifically, I made it to insert build time into program code). If I run project via build.xml "run" target, I get behavior I expect - the program displays build time and date. But if I run project using standard (and most obvious, used it always) button "Run Main Project", I get totally another result (no build date). Moreover, if I insert any code into build.xml, I still get result if I run the target explicitly and no result if it is run simply by NetBeans. And this leads me to conclusion, that this button uses another method to run my application. My question is: what does that button do? What method does it call? And can it be configured to run the needed target of make file?

• Error when using TransformToAncestor: "The specified Visual is not an ancestor of this Visual."

  - by Brian Sullivan

  I'm trying to get the offset of a control relative to the top of its window, but I'm running into trouble when using the TransformToAncestor method of the control. Note: this code is in a value converter which will convert from a control to its relative Y position in relation to the window. public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { var ctrl = (Control) value; var win = Window.GetWindow(ctrl); var transform = ctrl.TransformToAncestor(win); // Exception thrown here. var pt = transform.Transform(new Point(0, 0)); return pt.Y; } The call to Window.GetWindow works just fine, and returns the correct window object inside which the control resides. Am I misunderstanding what WPF thinks of as an "ancestor"? I would think that given the result of GetWindow, that window would be an ancestor of the control. Are there certain nesting patters that would cause the line of ancestry to be cut off at a certain point?

• How do I use a datetime variable with createparameter in classic ASP?

  - by Frank Schmitt

  I'm having a heck of a time trying to create a parameterized query that binds a date variable into a stored procedure call: twoyearsago = dateadd("yyyy", -2, date()) DataConn.ConnectionString = myConnectionString DataConn.Open Set rs = Server.CreateObject("ADODB.Recordset") Set DataCmd = Server.CreateObject("ADODB.Command") DataCmd.ActiveConnection = DataConn DataCmd.CommandText = "exec myStoredProc ?, ?" DataCmd.Parameters.Append DataCmd.CreateParameter("@start", adDate, , 10, date()) DataCmd.Parameters.Append DataCmd.CreateParameter("@end", adDate, , 10, twoyearsago) rs.Open DataCmd The stored proc returns nothing (indicating the dates aren't making it through). If I hard code dates in the query, e.g.: DataCmd.CommandText = "exec myStoredProc '01/01/2008', '01/01/2010'" I get the results I would expect. Calling CStr on my dates (if that makes a difference) returns them in the above format.

• ScoreNinja causes java.lang.RuntimeException: Can't create handler inside thread that has not called

  - by sirconnorstack

  I'm trying to add ScoreNinja, the global high score system, to my Android game, and it works fine when I load it on my phone, but when I release it into the wild, I got crash reports saying: java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare() Here is part of the call stack: android.os.Handler.<init>(Handler.java:121) android.app.Dialog.<init>(Dialog.java:99) android.app.AlertDialog.<init>(AlertDialog.java:65) android.app.AlertDialog.<init>(AlertDialog.java:61) android.app.AlertDialog$Builder.create(AlertDialog.java:797) android.app.AlertDialog$Builder.show(AlertDialog.java:812) com.scoreninja.adapter.ScoreNinjaAdapter.show(ScoreNinjaAdapter.java:136) com.scoreninja.adapter.ScoreNinjaAdapter.show(ScoreNinjaAdapter.java:99) I thought the main thread had prepare() called automatically, and if not, why would it work fine for me but not anyone else?

• Why does my .NET Windows service not start automatically sometimes?

  - by Tomek

  Hi all, I have modified a working Windows service that had always been starting beforehand. After adding the System.Management reference it now sometimes will not start automatically. I get the following error: Service cannot be started. System.Runtime.InteropServices.COMException (0x80010002): Call was canceled by the message filter. (Exception from HRESULT: 0x80010002 (RPC_E_CALL_CANCELED)) I found another post here on SO with someone having the same issue. http://stackoverflow.com/questions/998883/why-wont-my-net-windows-service-start-automatically-after-a-reboot However, the proposed solution was to have the service start after the services it depends on have started. However, when I go to the Dependencies tab for my service, I see: Should I just use the workaround method of putting the thread to sleep, or is there a more proper way of getting this service to start correctly? Is this happening because .NET has not started before my service starts? Thanks, Tomek

• REST api design to retrieve summary information

  - by Jacques René Mesrine

  I have a scenario in which I have REST API which manages a Resource which we will call Group. A Group is similar in concept to a discussion forum in Google Groups. Now I have two GET access method which I believe needs separate representations. The 1st GET access method retrieves the minimal amount of information about a Group. Given a *group_id* it should return a minimal amount of information like { group_id: "5t7yu8i9io0op", group_name: "Android Developers", is_moderated: true, number_of_users: 34, new_messages: 5, icon: "http://boo.com/pic.png" } The 2nd GET access method retrives summary information which are more statistical in nature like: { group_id: "5t7yu8i9io0op", top_ranking_users: { [ { user: "george", posts: 789, rank: 1 }, { user: "joel", posts: 560, rank: 2 } ...] }, popular_topics: { [ ... ] } } I want to separate these data access methods and I'm currently planning on this design: GET /group/:group_id/ GET /group/:group_id/stat Only the latter will return the statistical information about the group. What do you think about this ?

• not using partial mocking? do they also mean in web-app?

  - by 01

  Im learning Mockito and in chapter 16 they say you should not use partial mocking in new system. I disagree, for example in one of my actions i use partial mocking for static framework methods, sql calls, etc. I extracted the stuff into methods and then mock it in tests. Most of those methods are specific to this action and wont be call from other actions, so it not worth to extract special components. I agree that you shouldn't using partial mocking in frameworks, but not in hard to mock actions. What are minuses of using partial mocking in web-app?

• OpenGL view in an iPad splitview

  - by dc

  I'm attempting to add an OpenGL view (such as the one given in Apple's sample code) as the detail view of an iPad's splitview but am running into issues. I've taken the sample code from the base OpenGL project and attempted to add it as a subview of my DetailViewController - ie EAGLView *glview = [[EAGLView alloc] initWithFrame:CGRectMake(0,0,100,100)] but when I add it to the main view and call startAnimating on it, nothing at all happens. Any solutions to this? I have never worked with OpenGL before so perhaps I'm doing this all wrong.

• Need help understanding Generics, How To Abstract Types Question.

  - by kmacmahon

  I could use some really good links that explain Generics and how to use them. But I also have a very specific question, relater to working on a current project. Given this class constructor: public class SecuredDomainViewModel<TDomainContext, TEntity> : DomainViewModel<TDomainContext, TEntity> where TDomainContext : DomainContext, new() where TEntity : Entity, new() public SecuredDomainViewModel(TDomainContext domainContext, ProtectedItem protectedItem) : base(domainContext) { this.protectedItem = protectedItem; } And its creation this way: DomainViewModel d; d = new SecuredDomainViewModel<MyContext, MyEntityType>(this.context, selectedProtectedItem); Assuming I have 20 different EntityTypes within MyContext, is there any easier way to call the constructor without a large switch statement? Also, since d is DomainViewModel and I later need to access methods from SecuredDomainViewModel, it seems I need to do this: if (((SecuredDomainViewModel<MyContext, MyEntityType>)d).CanEditEntity) But again "MyEntityType" could actually be one of 20 diffent types. Is there anyway to write these types of statements where MyEntityType is returned from some sort of Reflection?

• Unexpected result in .NET 4 DirectoryInfo.EnumerateFiles(string)

  - by xkingpin

  It seems that the following code is not working as expected. I would assume that the following call to EnumarateFiles would only return files that match the filename pattern of c* ... however, filenames with H* are still getting returned. For example... the following file will get deleted in the following code (HNNN09060900932.xml). What's the issue? This is a major bug in my application. string searchPattern = "C*"; // get each file in this directory that is less than a given date var files = from file in SubDir.EnumerateFiles(searchPattern) where file.LastWriteTime < KeepDate select file; foreach (var file in files) { file.Delete(); }

• Facebook require_login not working

  - by kielie

  hi guys, I am having some trouble with my little facebook application, I keep getting this friggin error, "Fatal error: Call to undefined method Facebook::require_login()", now the funny bit is that my exact same code is working for other people, but not for me, here is the code. <?php require_once( "facebook-php-sdk/src/facebook.php" ); $api_key = "my_api_key"; $secret = "my_secret_key"; $facebook = new Facebook( $api_key, $secret ); $user_id = $facebook->require_login(); echo "Hello World"; echo "Current logged in as <fb:name uid=\"$user_id\" />"; ?> As you can see it is a simple hello USER application, but for some reason this REFUSES to work for me, so if anyone can help out that would be great, thanx in advance!

• jQuery Thickbox and Google Maps Extinfowindow

  - by cdonner

  I am trying to place a link into an Extinfowindow that obtains its content through an Ajax call. So, I click on a push pin marker, up pops the Extinfowindow with my ThickBox link in it, and when I inspect the DOM for the entire page at that point, I can see the element correctly showing up with the "thickbox" class. The link looks like this <A class="thickbox" title="" href="http://localhost:1293/Popup.aspx? height=200&width=300&modal=true">Modal Popup</A> However, when I click on it, it does a full refresh and the target page loads in the browser, not in a popup. It seems that when the <A> for the Thickbox control is injected into the DOM after the initial load, jQuery is no longer able to do its magic and intercept the anchor link request. Does anybody have thoughts about how to do this better?

• shell_exec escaping quotes in php for Twitter API

  - by yc10

  I'm (lazily) using shell_exec() to execute a Twitter API Call. shell_exec('curl -u user:password -d "id=3191321" http://api.twitter.com/1/twitterapi/twitterlist/members.xml'); That works fine when I authenticate correctly and put in a number for the id. But when I try to put in a variable ($id), it screws up. $addtolist = shell_exec('curl -u pxlist:Weekend1 -d "id='.$id.'" http://twitter.com/username/twitterlist/members.xml'); I tried flipping the quote types $addtolist = shell_exec("curl -u pxlist:Weekend1 -d 'id=$id' http://twitter.com/username/twitterlist/members.xml"); I tried using double quotes and escaping them $addtolist = shell_exec("curl -u pxlist:Weekend1 -d \"id=$id\" http://twitter.com/username/twitterlist/members.xml"); None of them worked. What am I doing wrong?

• memory not freed in matlab?

  - by noam

  I am running a script that animates a plot (simulation of a water flow). After a while, I kill the loop by doing ctrl-c. After doing this several times I get the error: ??? Error: Out of memory. And after I start receiving that error, every call to my script will generate it. Now, it happens before anything inside the function that I am calling is executed, i.e even if I add the line a=1 as the first line of the function I am calling, I still get the error and no printout, so the code inside the function doesn't even get executed. What could be causing this?

• printing in the same line in java.

  - by sil3nt

  Hi there, I have a base class called Items and 3 derived classes, and within the Items base class i have a print function of the form public void print(){ System.out.println("ID " + id + " Title " + title + " <" + year + "> "); } and within every derived class I call the Items print function through super.print(); which is followed by a specific print function relating to the derived class. My problem is, whenever the printing is executed from one of the derived classes the printed text is not on the same line. So super.print() will be in the line above the derived class print function. How do I get them both to be on the same line?

• WPF Canvas Binding

  - by morsanu

  Hey guys, I'm rather new to WPF, so maybe this is a simple question. I have a class that derives from Canvas, let's call it MyCanvas. And I have a class, MyClass, that has a property of type MyCanvas. In XAML, I built a TabControl, so each TabItem binds to a MyClass object. Now, in the Content of every tab I want to display MyObject.MyCanvas. How should I do that? <TabControl.ContentTemplate> <DataTemplate> <Grid> <myCanvas:MyCanvas Focusable="true" Margin="10" > <Binding Path="Canvas"></Binding> </screenCanvas:ScreenCanvas> </Grid> </DataTemplate> </TabControl.ContentTemplate>

• How to use Win32 SetCursor() with WPF resource and HwndHost

  - by Hank

  We have an HwndHost UIElement in our WPF application which is used to display Direct3d graphics, and the only way I have found to set a cursor for the HwndHost UIElment is to call the Win32 API SetCursor(). All of our cursors are resources in managed assemblies, and I would prefer to not change that, but I have not been able to find a way to load one of these cursors via any Win32 APIs like LoadImage(). Does anybody know how to get a handle(hCursor) to a cursor which is a resource in a managed assembly? Or, is there another way to set a cursor on an HwndHost displaying Direct3D graphics?

• manipulate objects outside svg with javascript-function inside the svg

  - by Christian Benke

  Hello! I'm embedding a svg-graphic on my website and i'd like to manipulate the rest of the website with javascript-commands which are in the svg - though i'm not sure if this is possible. Let me elaborate: I've got a worldmap in svg, i want to click on a country and this click should run an ajax-call and load relevant information of this country into a div in the html site where the svg is embedded. "onclick="location.href='xxx'"" redirects to the respective site which is fine, but i'd prefer to run a js-function that fetches the site with ajax - but running a javascript-function in the svg only seems to work for functions and elements defined in the svg, not outside of it. Is it basically possible to manipulate anything outside the svg through a js-function in the svg? How? Regards Christian

• Java method for android:layout_gravity

  - by André Leitão

  Hi folks, I would like to know if is there a way to call android:layout_gravity property from a java method. I didn't found any method in Android documentation to do it. This is the picture of the layout I want to implement: I know to do it through xml, as following: <FrameLayout xlmns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content"> <Button android:layout_gravity="left|center_vertical" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="<" /> <Button android:layout_gravity="right|center_vertical" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text=">" /> </FrameLayout> But in my situation, I need to do it through Java code, because I'll implement another layout views dinamically. To avoid merging xml layout with Java code, I would prefer make all layout using Java. Can you help me? Thanks. André Leitão
