  • {DCC Warning} W1036 Variable '$frame' might not have been initialized?

    - by Gad D Lord
    Any ideas why I get this warning in Delphi XE: [DCC Warning] Form1.pas(250): W1036 Variable '$frame' might not have been initialized procedure TForm1.Action1Execute(Sender: TObject); var Thread: TThread; begin ... Thread := TThread.CreateAnonymousThread( procedure{Anonymos}() procedure ShowLoading(const Show: Boolean); begin /// <------------- WARNING IS GIVEN FOR THIS LINE (line number 250) Thread.Synchronize(Thread, procedure{Anonymous}() begin ... Button1.Enabled := not Show; ... end ); end; var i: Integer; begin ShowLoading(true); try Thread.Synchronize(Thread, procedure{Anonymous}() begin ... // some UI updates end Thread.Synchronize(Thread, procedure{Anonymous}() begin ... // some UI updates end ); finally ShowLoading(false); end; end ).NameThread('Some Thread Name'); Thread.Start; end; I do not have anywhere in my code a variable names frame nor $frame. I am even not sure how $frame with $ sign can be a valid identifier. Smells like compiler magic to me. PS: Of course the real life xosw is having other than Form1, Button1, Action1 names.

  • Is it possible to receive SMS message on appWidget?

    - by cappuccino
    Is it possible to receive SMS message on appWidget? I saw android sample source(API Demos). In API Demos, ExampleAppWidgetProvider class extends AppWidgetProvider, not Activity. So, I guess it is impossible to regist SMS Receiver like this, rcvIncoming = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { Log.i("telephony", "SMS received"); Bundle data = intent.getExtras(); if (data != null) { // SMS uses a data format known as a PDU Object pdus[] = (Object[]) data.get("pdus"); String message = "New message:\n"; String sender = null; for (Object pdu : pdus) { SmsMessage part = SmsMessage.createFromPdu((byte[])pdu); message += part.getDisplayMessageBody(); if (sender == null) { sender = part.getDisplayOriginatingAddress(); } } Log.i(sender, message); } } }; registerReceiver(rcvIncoming, new IntentFilter("android.provider.Telephony.SMS_RECEIVED")); My goal is to receive SMS message on my custom appWidget. Any help would be appreciated!!

  • How to name multiple versioned ServiceContracts in the same WCF service?

    - by Tor Hovland
    When you have to introduce a breaking change in a ServiceContract, a best practice is to keep the old one and create a new one, and use some version identifier in the namespace. If I understand this correctly, I should be able to do the following: [ServiceContract(Namespace = "http://foo.com/2010/01/14")] public interface IVersionedService { [OperationContract] string WriteGreeting(Person person); } [ServiceContract(Name = "IVersionedService", Namespace = "http://foo.com/2010/02/21")] public interface IVersionedService2 { [OperationContract(Name = "WriteGreeting")] Greeting WriteGreeting2(Person2 person); } With this I can create a service that supports both versions. This actually works, and it looks fine when testing from soapUI. However, when I create a client in Visual Studio using "Add Service Reference", VS disregards the namespaces and simply sees two interfaces with the same name. In order to differentiate them, VS adds "1" to the name of one of them. I end up with proxies called ServiceReference.VersionedServiceClient and ServiceReference.VersionedService1Client Now it's not easy for anybody to see which is the newer version. Should I give the interfaces different names? E.g IVersionedService1 IVersionedService2 or IVersionedService/2010/01/14 IVersionedService/2010/02/21 Doesn't this defeat the purpose of the namespace? Should I put them in different service classes and get a unique URL for each version?

  • How can I increment a counter every N loops in JMeter?

    - by Dave Hunt
    I want to test concurrency, and reliably replicate an issue that JMeter brought to my attention. What I want to do is set a unique identifier (currently the time in milliseconds with a counter appended) and increment the counter between loops but not between threads. The idea being that the number of threads I have set up is the number of identical identifiers before incrementing and using another. If I had 3 threads with a loop count of 2 I want: 1. Unique ID: <current-time-in-millis>000000 2. Unique ID: <current-time-in-millis>000000 3. Unique ID: <current-time-in-millis>000000 4. Unique ID: <current-time-in-millis>000001 5. Unique ID: <current-time-in-millis>000001 6. Unique ID: <current-time-in-millis>000001 I've tried using Throughput Controllers to increment a counter, as well as several other things that seemed they should work but had no luck. This seems like something JMeter should be able to do. Is there any way to get the value of the loop count?

  • No resource type specified (at 'id' with value '@+id\st')

    - by Refaat
    I'm new at android programming, I'm now trying to make some buttons, I configured these buttons using the following code: The MainActivity class : public class MainActivity extends Activity { /** Called when the activity is first created. */ Button st,nd,center; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); st = (Button)findViewById(R.id.st); st = (Button)findViewById(R.id.center); st = (Button)findViewById(R.id.nd); } } and the XML Layout: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@drawable/background" > <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Hello from animation!!" /> <button android:layout_width="100dp" android:layout_height="50dp" android:text="1st half" android:id="@+id\st" /> // and the other two points defined the same way </LinearLayout> And i got that syntax error: error: Error: No resource type specified (at 'id' with value '@+id\st'). // and the same error with the other two buttons HINT: The R class is imported and accessible from the MainActivity class but it can't read R.id.

  • Why am I getting "Message sent to deallocated object" in Objective-C?

    - by Dave C
    I have several buttons on my app that are being created dynamically. They are all pointed at the button click event when pressed. When the button pressed method is called, the sender's tag (int value) is parsed into the controller's house ID. It works with one of the buttons — the first one created, to be specific — but the others throw the following error: -[CFNumber intValue]: message sent to deallocated instance 0xc4bb0ff0 I am not releasing these buttons anywhere in my code. I haven't set them to autorelease or anything like that. I'm just wondering why they are doing this on the click. The button click event: - (IBAction) ButtonClick: (id) sender { HouseholdViewController *controller = [[HouseholdViewController alloc] initWithNibName:@"HouseholdViewController" bundle:nil]; controller.delegate = self; controller.HouseID = [(NSInteger)[(UIButton *)sender tag] intValue]; //this line throws an error controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:controller animated:YES]; [controller release]; } Where I am creating the buttons: UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; button.frame = CGRectMake(MyLongInScreenCoords, MyLatInScreenCoords, 50, 50); UIImage *buttonImageNormal = [UIImage imageNamed:@"blue_pin.png"]; UIImage *strechableButtonImageNormal = [buttonImageNormal stretchableImageWithLeftCapWidth:50 topCapHeight:50]; [button setBackgroundImage:strechableButtonImageNormal forState:UIControlStateNormal]; [self.view addSubview:button]; button.tag = [NSNumber numberWithInt:[[words objectAtIndex: i] intValue]]; ButtonPoints[CurrentHouseCount][0] = button; ButtonPoints[CurrentHouseCount][1] = [NSValue valueWithCGPoint:CGPointMake(MyActualLat, MyActualLong)]; [button addTarget:self action:@selector(ButtonClick:) forControlEvents:UIControlEventTouchUpInside]; CurrentHouseCount++;

  • Customizing the TFS 2008 build sequence to avoid compilation and deploy SSRS

    - by Andrew
    I'm trying to create a CI process for SQL Server Reporting Services. I am fairly new to TFS but quite experienced with MSBuild. In the past I've used a combination of MSBuild with Team City so the whole build process is more or less custom. Here lies the start of my problems, as the solution I am deploying only contains Report Server projects (rds), no compilation is required. I thought that I would override the the first default task that TFS runs (EndToEndIteration) to override the default TFS build sequence and inject my own. The first snag that I have come across is that the build always fails, how can I set the status of the build to success? Currently the EndToEndIteration task is very light and only has a message. Is this the best method to create a custom build process in TFS where compilation is not required? Or should I use the default sequence and override one of the hook tasks mentioned in http://msdn.microsoft.com/en-us/library/aa337604%28VS.80%29.aspx (ie: AfterCompile) The core steps that I'd like to achieve are: Bundle the RDL and datasource files Connect to the host server to register/deploy the reports Re-apply any subscriptions that previously existed Run tests to verify the deployment succeeded and is returning results as expected I have found another article on Report services deployment: http://stackoverflow.com/questions/88710/reporting-services-deployment But it doesn't mention the best practice for customizing the standard build process. Any help would be appreciated.

  • register device at run time

    - by user177893
    In the App ID section of the Program Portal, locate the App ID you wish to use with the Apple Push Notification service. Only App IDs with a specific bundle ID can be used with the APNs. You cannot use a “wild-card” application ID. You must see “Available” under the Apple Push Notification service column to register this App ID and configure a certificate for this App ID. Click the ‘Configure’ link next to your desired App ID. In the Configure App ID page, check the Enable Push Notification Services box and click the Configure button. Clicking this button launches the APNs Assistant, which guides you through the next series of steps that create your App ID specific Client SSL certificate. Download the Client SSL certificate file to your download location. Navigate to that location and double-click the certificate file (which has an extension of cer) to install it in your keychain. When you are finished, click Done in the APNS Assistant. Double-clicking the file launches Keychain Access. Make sure you install the certificate in your login keychain on the computer you are using for provider development. The APNs SSL certificate should be installed on your notification server. When you finish these steps you are returned to the Configure App ID page of the iPhone Dev Center portal. The certificate should be badged with a green circle and the label “Enabled”. To complete the APNs set-up process, you will need to create a new provisioning profile containing your APNs-enabled App ID. IS it posssible to do theses steps through code.

  • Memory leak in Apples 'Scrolling' sample code

    - by John
    Hi All, I'm using code based on Apple's "Scrolling" sample code - here's where I have a problem: // load all the images from our bundle and add them to the scroll view NSUInteger i; for (i = 1; i <= jNumImages; i++) { NSString *imageName = [NSString stringWithFormat:@"page%d.png", i]; UIImage *image = [UIImage imageNamed:imageName]; UIImageView *imageView2 = [[UIImageView alloc] initWithImage:image]; The UIImageView causes a leak - it doesn't seem to be releasing (though I do state [imageView2 release]; after adding the imageView as a subView to scrollView2 I have say 15 chapters of a book each held in a nav bar, each containing a scroll view with one chapters worth of these image views (each image is a page). When I get to around the second last chapter the app crashes due to the memory leaks... really annoying! I think it might be because imageView's been alloc'd twice (in alloc and in addSubView) but i'm not sure.... tried releasing twice but it didn't seem to help. any pointers? Thanks in advance ^.^

  • Oracle command hangs when using view for "WHILE x IN..." subquery

    - by Calvin Fisher
    I'm working on a web service that fetches data from an oracle data source in chunks and passes it back to an indexing/search tool in XML format. I'm the C#/.NET guy, and am kind of fuzzy on parts of Oracle. Our Oracle team gave us the following script to run, and it works well: SELECT ROWID, [columns] FROM [table] WHERE ROWID IN ( SELECT ROWID FROM ( SELECT ROWID FROM [table] WHERE ROWID > '[previous_batch_last_rowid]' ORDER BY ROWID ) WHERE ROWNUM <= 10000 ) ORDER BY ROWID 10,000 rows is an arbitrary but reasonable chunk size and ROWID is sufficiently unique for our purposes to use as a UID since each indexing run hits only one table at a time. Bracketed values are filled in programmatically by the web service. Now we're going to start adding views to the indexing, each of which will union a few separate tables. Since ROWID would no longer function as a unique identifier, they added a column to the views (VIEW_UNIQUE_ID) that concatenates the ROWIDs from the component tables to construct a UID for each union. But this script does not work, even though it follows the same form as the previous one: SELECT VIEW_UNIQUE_ID, [columns] FROM [view] WHERE VIEW_UNIQUE_ID IN ( SELECT VIEW_UNIQUE_ID FROM ( SELECT VIEW_UNIQUE_ID FROM [view] WHERE ROWID > '[previous_batch_last_view_unique_id]' ORDER BY VIEW_UNIQUE_ID ) WHERE ROWNUM <= 10000 ) ORDER BY VIEW_UNIQUE_ID It hangs indefinitely with no response from the Oracle server. I've waited 20+ minutes and the SQLTools dialog box indicating a running query remains the same, with no progress or updates. I've tested each subquery independently and each works fine and takes a very short amount of time (<= 1 second), so the view itself is sound. But as soon as the inner two SELECT queries are added with "WHERE VIEW_UNIQUE_ID IN...", it hangs. Why doesn't this query work for views? In what important way are they not interchangeable here?

  • Cucumber-rails on jruby installs gem into my apps root directory with bundler

    - by brad
    Just installed cucumber 0.7.2 and cucumber-rails 0.3.1 with jruby-1.4.0 on OSX. When I run a bundle install, it places a cucumber-rails directory in my main app with all of the gem code/dependencies. First off, this is definitely not what I want and I'm not sure why this happens for cucumber-rails only. Second, if I delete this folder and just manually install cucumber-rails, when I run script/generate feature blah I get /Users/bradrobertson/.rvm/rubies/jruby-1.4.0/lib/ruby/site_ruby/1.8/rubygems/source_index.rb:344:in `refresh!': source index not created from disk (RuntimeError) from /Users/bradrobertson/.rvm/gems/jruby-1.4.0/gems/rails-2.3.5/lib/rails/vendor_gem_source_index.rb:34:in `refresh!' from /Users/bradrobertson/.rvm/gems/jruby-1.4.0/gems/rails-2.3.5/lib/rails/vendor_gem_source_index.rb:29:in `initialize' from /Users/bradrobertson/.rvm/gems/jruby-1.4.0/gems/rails-2.3.5/lib/rails/gem_dependency.rb:21:in `new' from /Users/bradrobertson/.rvm/gems/jruby-1.4.0/gems/rails-2.3.5/lib/rails/gem_dependency.rb:21:in `add_frozen_gem_path' from /Users/bradrobertson/.rvm/gems/jruby-1.4.0/gems/rails-2.3.5/lib/initializer.rb:298:in `add_gem_load_paths' from /Users/bradrobertson/.rvm/gems/jruby-1.4.0/gems/rails-2.3.5/lib/initializer.rb:132:in `process' from /Users/bradrobertson/.rvm/gems/jruby-1.4.0/gems/rails-2.3.5/lib/initializer.rb:113:in `run' from /Users/bradrobertson/Repos/app/source/trunk/config/environment.rb:13 from /Users/bradrobertson/Repos/app/source/trunk/config/environment.rb:1:in `require' from /Users/bradrobertson/.rvm/gems/jruby-1.4.0/gems/rails-2.3.5/lib/commands/generate.rb:1 from /Users/bradrobertson/.rvm/gems/jruby-1.4.0/gems/rails-2.3.5/lib/commands/generate.rb:3:in `require' from script/generate:3 Similarly running rake cucumber I get rake aborted! source index not created from disk So something obviously doesn't work. If I add that cucumber-rails directory back in, then my rake cucumber actually runs. Can someone tell me why it would need to install the gem right in my rails app? I've never seen this before. setup jruby-1.4.0 cucumber-0.7.2 cucumber-rails 0.3.1 bundler 0.9.23 webrat 0.7.1

  • Why are symbols not frozen strings?

    - by Alex Chaffee
    I understand the theoretical difference between Strings and Symbols. I understand that Symbols are meant to represent a concept or a name or an identifier or a label or a key, and Strings are a bag of characters. I understand that Strings are mutable and transient, where Symbols are immutable and permanent. I even like how Symbols look different from Strings in my text editor. What bothers me is that practically speaking, Symbols are so similar to Strings that the fact that they're not implemented as Strings causes a lot of headaches. They don't even support duck-typing or implicit coercion, unlike the other famous "the same but different" couple, Float and Fixnum. The mere existence of HashWithIndifferentAccess, and its rampant use in Rails and other frameworks, demonstrates that there's a problem here, an itch that needs to be scratched. Can anyone tell me a practical reason why Symbols should not be frozen Strings? Other than "because that's how it's always been done" (historical) or "because symbols are not strings" (begging the question). Consider the following astonishing behavior: :apple == "apple" #=> false, should be true :apple.hash == "apple".hash #=> false, should be true {apples: 10}["apples"] #=> nil, should be 10 {"apples" => 10}[:apples] #=> nil, should be 10 :apple.object_id == "apple".object_id #=> false, but that's actually fine All it would take to make the next generation of Rubyists less confused is this: class Symbol < String def initialize *args super self.freeze end (and a lot of other library-level hacking, but still, not too complicated) See also: http://onestepback.org/index.cgi/Tech/Ruby/SymbolsAreNotImmutableStrings.red http://www.randomhacks.net/articles/2007/01/20/13-ways-of-looking-at-a-ruby-symbol Why does my code break when using a hash symbol, instead of a hash string? Why use symbols as hash keys in Ruby? What are symbols and how do we use them? Ruby Symbols vs Strings in Hashes Can't get the hang of symbols in Ruby

  • jQuery multiple themes on one page

    - by lloydphillips
    This is driving me NUTS! I've followed the post here which just doesn't seem to be working: http://www.filamentgroup.com/lab/using_multiple_jquery_ui_themes_on_a_single_page/ I have a base theme, for examples sake it's the Smoothness theme from the jQuery UI gallery. Then I have a 'red' theme which basically colours the buttons red. Here is the theme I created. So I go to download my theme. Choose Advanced settings, set the scope to 'red' and my theme folder name to 'red' and download. First of all I'm not entirely 100% sure which folder I'm to copy over to my project is it the 'development-bundle\themes' folder (which contains my red folder) or the '\css\red' folder? I've tried both. The post above seems to suggest if I copy my themes folder and link to my theme in the css it'll work when I add a class of 'red' to a wrapper div or element. So I've linked the themes like so in my file: <link type="text/css" href="themes/base/jquery.ui.all.css" rel="stylesheet" /> <link type="text/css" href="themes/red/jquery.ui.all.css" rel="stylesheet" /> The base theme loads and works all honkey doorey but the red theme doesn't. I've got a button styled like so: <input type="submit" id="btn" value="A submit button" class="red" /> I've also tried: <div class="red"> <input type="submit" id="btn" value="A submit button" /> </div> Neither work. When I remove the 'themes/base/jquery.ui.all.css' css file link the button's aren't styled at all. Crazy! I'm pulling my hair out. Where am I going wrong? Surely they should just make it easy enough to download JUST the theme folder and reference the ui.all file.

  • drupal: standard way for creating a slug from a string

    - by egarcia
    Hi there, A slug on this context is a string that its safe to use as an identifier, on urls or css. For example, if you have this string: I'd like to eat at McRunchies! Its slug would be: i-d-like-to-eat-at-mcrunchies- I want to know whether there's a standard way of building such strings on Drupal (or php functions available from drupal). More precisely, inside a Drupal theme. Context: I'm modifying a drupal theme so the html of the nodes it generates include their taxonomy terms as css classes on their containing div. Trouble is, some of those terms' names aren't valid css class names. I need to "slugify" the them. I've read that some people simply do this: str_replace(" ", "-", $term->name) This isn't really a enough for me. It doesn't replace uppercase letters with downcase, but more importantly, doesn't replace non-ascii characters (like à or é) by their ascii equivalents. Is there a function in drupal 6 (or the php libs) that provides a way to slugify a string, and can be used on a template.php file of a drupal theme?

  • User preferences using SQL and JavaScript

    - by Shyam
    Hi, I am using Server Side JavaScript - yes, I am actually using Server Side JavaScript. To complexify things even more, I use Oracle as a backend database (10g). With some crazy XSLT and mutant-like HTML generation, I can build really fancy web forms - yes, I am aware of Rails and other likewise frameworks and I choose the path of horror instead. I have no JQuery or other fancy framework at my disposal, just plain ol' JavaScript that should be supported by the underlying engine called Mozilla Rhino. Yes, it is insane and I love it. So, I have a bunch of tables at my disposal and some of them are filled with associative keys that link to values. As I am a people pleaser, I want to add some nifty user-preference driven solutions. My users have all an unique user_id and this user_id is available during the entire session. My initial idea is to have a user preference table, where I have "three" columns: user_id, feature and pref_string. Using a delimiter, such as : or - (haven't thought about a suitable one yet), I could like store a bunch of preferences as a list and store its elements inside an array using the .split-method (similar like the PHP-explode function). The feature column could be like the table name or some identifier for the "feature" i want to link preferences too. I hate hardcoding objects, especially as I want to be able to back these up and reuse this functionality application-wide. Of course I would love better ideas, just keep in mind I cannot just add a library that easily. These preferences could be like "joined" to the table, so I can query it and use its values. I hope it doesn't sounds too complex, because well.. its basically something really simple I need. Thanks!

  • Transitioning from FlexBuilder 3 to FlashBuilder 4 ... there and back again.

    - by Robusto
    It's growing pains time again. Some of our stuff requires FlashBuilder 4 and some still requires FlexBuilder 3. Both are installed OK, and no projects use both IDEs. The trouble is, when I go back to work on a FlexBuilder 3 project it takes freakin' forever to build and I get weird errors like these: This doesn't seem to cause any identifiable problems except to throw up a modal dialog at various points in the build process, forcing user interaction. But I do notice that memory fills up fast in FB3 and generally FB3 starts behaving strangely and ultimately quits once it gets up over 700MB. This is only a temporary bridge situation until we get all projects into FB4, but "temporary" could mean weeks if not months. Does anyone have any advice for how to get through this bridge period? Is there anything I can do to make these two IDEs work and play well together? Failing that, does anyone know what "java.lang.String" is the "reason" for the problem? Does Eclipse have a resource bundle somewhere that is getting corrupted when i go back and forth between the two?

  • iphone - moving from one view to another

    - by codemonkey
    Hi there, I am getting started with iphone development and am trying to move from one view to another. I have a main view (NearestPhotosViewController) which basically acts as a menu for my app. I then have a second view (DisplayNearestPhotos). I come from a web (html) background so what i'm trying to do here in web terms is click a button (link) on the NearestPhotosViewController view to then display the DisplayNearestPhotos view. I have been looking around for some code to do this (I don't think it's as simple as doing the equivelent in html). The following code is hooked up to a button on my menu view. -(IBAction)ButtonPressed:(id)sender { DisplayNearestPhotos *views = [[DisplayNearestPhotos alloc] initWithNibName:nil bundle:nil]; [self presentModalViewController:views animated:YES]; views.release; } The above code works (it displays the second view) but what i'd like to know is, is that the correct way to do it? If not, what is the correct way to move from one view to another? Thank you in advance

    I was playing with Visual Studio and templates. Consider this code struct Foo { struct Bar { }; static const int Bar=42; }; template<typename T> void MyFunction() { typename T::Bar f; } int main() { MyFunction<Foo>(); return 0; } When I compile this is either Visual Studio 2008 and 11, I get the following error error C2146: syntax error : missing ';' before identifier 'f' Is Visual Studio correct in this regard ? Is the code violating any standards ? If I change the code to struct Foo { struct Bar { }; static const int Bar=42; }; void SecondFunction( const int& ) { } template<typename T> void MyFunction() { SecondFunction( T::Bar ); } int main() { MyFunction<Foo>(); return 0; } it compiles without any warnings. In Foo::BLAH a member preferred over a type in case of conflicts ?

  • call addsubview again causes slowdown

    - by Tom
    hi guys, i am writing a little music-game for the iphone. I am almost done, this is the only issue which keeps me from rolling it out. any help to solve this is much appreciated. this is what i do: at my appDelegate I add my menu-view-screen to the window. the menu-view-screen acts as a container and controls which view gets presented to the user. means, on the menu-view-screen I got 4 buttons (new game, options, faq, highscore). when the user clicks on a button something as this happens: if (self.gameViewController == nil) { GameViewController *viewController = [[GameViewController alloc] initWithNibName:@"GameViewController" bundle:nil]; self.gameViewController = viewController; [viewController release]; } [self.view addSubview:self.gameViewController.view]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleSwitchViewNotificationFromGameView:) name:@"SwitchView" object:gameViewController]; when the user returns to the menu, this piece of code gets executed: [[NSNotificationCenter defaultCenter] removeObserver:self]; [self.gameViewController viewWillDisappear:YES]; [self.gameViewController.view removeFromSuperview]; this works fine for all screens but not for the gamescreen(well this is the only one with heaps of user-interaction) means the responsiveness of the iphone(when playing tones) gets really slow. The performance is fine when I display the gameview for the first time. it starts getting slower as soon as I add it to the menu-views-container-subviews again (addsubview) (basically open up a new game) any ideas what causes(or to get around) this? thanks heaps Best regards Tom

  • Pass Parameter to Subroutine in Codebehind

    - by Sanjubaba
    I'm trying to pass an ID of an activity (RefNum) to a Sub in my codebehind. I know I'm supposed to use parentheses when passing parameters to subroutines and methods, and I've tried a number of ways and keep receiving the following error: BC30203: Identifier expected. I'm hard-coding it on the front-end just to try to get it to pass [ OnDataBound="FillSectorCBList("""WK.002""")" ], but it's obviously wrong. :( Front-end: <asp:DetailsView ID="dvEditActivity" AutoGenerateRows="False" DataKeyNames="RefNum" OnDataBound="dvSectorID_DataBound" OnItemUpdated="dvEditActivity_ItemUpdated" DataSourceID="dsEditActivity" > <Fields> <asp:TemplateField> <ItemTemplate> <br /><span style="color:#0e85c1;font-weight:bold">Sector</span><br /><br /> <asp:CheckBoxList ID="cblistSector" runat="server" DataSourceID="dsGetSectorNames" DataTextField="SectorName" DataValueField="SectorID" OnDataBound="FillSectorCBList("""WK.002""")" ></asp:CheckBoxList> <%-- Datasource to populate cblistSector --%> <asp:SqlDataSource ID="dsGetSectorNames" runat="server" ConnectionString="<%$ ConnectionStrings:dbConn %>" ProviderName="<%$ ConnectionStrings:dbConn.ProviderName %>" SelectCommand="SELECT SectorID, SectorName from Sector ORDER BY SectorID"></asp:SqlDataSource> </ItemTemplate> </asp:TemplateField> </Fields> </asp:DetailsView> Code-behind: Sub FillSectorCBList(ByVal RefNum As String, ByVal sender As Object, ByVal e As System.EventArgs) Dim SectorIDs As New ListItem Dim myConnection As String = ConfigurationManager.ConnectionStrings("dbConn").ConnectionString() Dim objConn As New SqlConnection(myConnection) Dim strSQL As String = "SELECT DISTINCT A.RefNum, AS1.SectorID, S.SectorName FROM Activity A LEFT OUTER JOIN Activity_Sector AS1 ON AS1.RefNum = A.RefNum LEFT OUTER JOIN Sector S ON AS1.SectorID = S.SectorID WHERE A.RefNum = @RefNum ORDER BY A.RefNum" Dim objCommand As New SqlCommand(strSQL, objConn) objCommand.Parameters.AddWithValue("RefNum", RefNum) Dim ad As New SqlDataAdapter(objCommand) Try [Code] Finally [Code] End Try objCommand.Connection.Close() objCommand.Dispose() objConn.Close() End Sub Any advice would be great. I'm not sure if I even have the right approach. Thank you!

  • Why are Managed Beans not loaded in Tomcat?

    - by c0d3x
    Hi, I created a JSF 2 web application with facelets. The libs for JSF where stored at tomcat/lib, to share it between several applications. I thought maybe it would be better to store the libs inside the WEB-INF/lib folder of the application, to get the application more independent from server configurations. Now when I start tomcat via eclipse, the managed beans are loaded and working. But when I start tomcat directly / standalone the managed beans are not loaded automatically. I used @ManagedBean @SessionScoped / @RequestScoped annotations to declare classes as managed beans. Why is this? What can I do to fix it? I don't use any faces-config.xml file yet. Thanks in advance. edited: Maybe this helps to see whats going on: javax.el.PropertyNotFoundException: /Artikel.xhtml @12,108 value="#{artikelBackingBean.nameFilterPattern}": Target Unreachable, identifier 'artikelBackingBean' resolved to null at com.sun.faces.facelets.el.TagValueExpression.getType(TagValueExpression.java:93) at com.sun.faces.renderkit.html_basic.HtmlBasicInputRenderer.getConvertedValue(HtmlBasicInputRenderer.java:95) at javax.faces.component.UIInput.getConvertedValue(UIInput.java:1008) at javax.faces.component.UIInput.validate(UIInput.java:934) at javax.faces.component.UIInput.executeValidate(UIInput.java:1189) at javax.faces.component.UIInput.processValidators(UIInput.java:691) at javax.faces.component.UIForm.processValidators(UIForm.java:243) at javax.faces.component.UIComponentBase.processValidators(UIComponentBase.java:1080) at javax.faces.component.UIViewRoot.processValidators(UIViewRoot.java:1180) at com.sun.faces.lifecycle.ProcessValidationsPhase.execute(ProcessValidationsPhase.java:76) at com.sun.faces.lifecycle.Phase.doPhase(Phase.java:101) at com.sun.faces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:118) at javax.faces.webapp.FacesServlet.service(FacesServlet.java:312) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:433) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:128) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:293) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:849) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:454) at java.lang.Thread.run(Thread.java:619)

  • How can I provide users with the functionality of the DBUnit DatabaseOperation methods from a web in

    - by reckoner
    I am currently updating a java-based web application which allows database developers to create stored procedure regression test suites for database testing. Currently, for test setup, execution and clean-up stages, the user is provided with text boxes where they are able to enter SQL code which is executed by the isql command. I would like to extend the application to use DB Unit’s DatabaseOperation methods to provide more ways to setup the state of the database than just SQL statements. The main reason for using Db Unit rather than just SQL statements is to be able to create and store xml and xls DataSets on a server where they can be associated with their test cases and used for data setup. My question is: How can I provide users with the functionality of the DBUnit DatabaseOperation methods from a web interface? I have considered: Creating a simple programming language and a parser to read some simple syntax involving the DB Unit method names which accept a parameter being the file location to an xml or xls DataSet. I was thinking of allowing the user to register the files they need with the web app which would catalogue them and provide each file with an identifier which could passed as a parameter to the methods in this simple programming language. Creating an XML DTD which provides the user with the ability to specify operations and parameters. If I went this approach, how can I execute the methods and their parameters that I parse from the XML document? Creating a table in the database which stores the method and a FK relation to a catalogued DataSet file, however I don’t think this would be good solution due to the fact that data entry would be tedious. Thanks for your help.

  • questions about name mangling in C++

    - by Tim
    I am trying to learn and understand name mangling in C++. Here are some questions: (1) From devx When a global function is overloaded, the generated mangled name for each overloaded version is unique. Name mangling is also applied to variables. Thus, a local variable and a global variable with the same user-given name still get distinct mangled names. Are there other examples that are using name mangling, besides overloading functions and same-name global and local variables ? (2) From Wiki The need arises where the language allows different entities to be named with the same identifier as long as they occupy a different namespace (where a namespace is typically defined by a module, class, or explicit namespace directive). I don't quite understand why name mangling is only applied to the cases when the identifiers belong to different namespaces, since overloading functions can be in the same namespace and same-name global and local variables can also be in the same space. How to understand this? Do variables with same name but in different scopes also use name mangling? (3) Does C have name mangling? If it does not, how can it deal with the case when some global and local variables have the same name? C does not have overloading functions, right? Thanks and regards!
