  • Edit dialog, with bindings and OK/Cancel in WPF

    - by Erik
    How can i have a dialog for editing the properties of a class with binding, and have OK-Cancel in the dialog? My first idea was this: public partial class EditServerDialog : Window { private NewsServer _newsServer; public EditServerDialog(NewsServer newsServer) { InitializeComponent(); this.DataContext = (_newsServer = newsServer).Clone(); } private void ButtonClick(object sender, RoutedEventArgs e) { switch (((Button)e.OriginalSource).Content.ToString()) { case "OK": _newsServer = (NewsServer)this.DataContext; this.Close(); break; case "Cancel": this.Close(); break; } } } When in the switch, case "OK", the DataContext contains the correct information, but the originally passed NewsServer instance does not change.

  • How to create a Clob in JPA in an implementation agnostic way

    - by kazanaki
    Hello I am using Ejb3 and JPA (based on Hibernate and Oracle 10g at the moment) I have an entity that contains a clob @Entity @Table(name = "My_TAB") public class ExampleEntity implements java.io.Serializable { private Clob someText; public void setSomeText(Clob someText) { this.someText= someText; } @Column(name = "COLUMN_NAME") public Clob getSomeText() { return this.someText; } Then I want to save an entity of this type. At the moment I am doing the following which works perfectly ExampleEntity exampleEntity = new ExampleEntity(); exampleEntity.setSomeText(Hibernate.createClob(aStringValue)); someOtherDao.save(exampleEntity); However this ties my code to Hibernate! I have specifically avoided so far Hibernate extensions and used only JPA annotations. The code works because indeed Hibernate is my current implementation. Is there some sort of JPA API that allows me to create a clob in a generic way? So if later I decide to switch to Toplink/EclipseLink or something else I won't have to change a thing?

  • RadGrid cannot pass sortExpression to ObjectDataSourceControl

    - by Jeff
    I have a Telerik RadGrid that bound to a datasource object. They are configured to support custom paging, sorting. For paging, only the data of a page is retrieved from the database. Before sorting, it works fine. The select method of the datasource is like public List<xxx> Select(string sortExpression, int maximumRows, int startRowIndex) {} Before sorting the sortExpression is empty, which is expected. But after use click sort, in the OnSortCommand event handler of Radgrid, the SortExpression is correct, indicating RadGrid has caputre user's sorting correctly. protected void OnSort(object source, GridSortCommandEventArgs e) { Console.WriteLine(e.SortExpression); // correct } But what is strange is that the RadGrid does not pass parameter to DataSource correctly this time. sortExpression is still empty, maximumRows became int.Max, and startRowIndex is 0. The the sorting in still render correctly, but grid ask datasource to get all data and do the sorting locally. Is this bug of RadGrid or my configuration is wrong?

  • Android Map Performance poor because of many Overlays?

    - by Dave
    Hi, I have a map in my android application that shows many markers (~20-50). But the app performs very poor when i try to scroll/zoom (in Google Android Maps i did a sample search for pizza and there were also some 20-50 results found and i didn't notice any particular performance problems when zooming/scrolling through the map). Here is my (pseudo)code: onCreate() { .... drawable = this.getResources().getDrawable(R.drawable.marker1); itemizedOverlay = new MyItemizedOverlay(drawable,mapView); ... callWebServiceToRetrieveData(); createMarkers(); } createMarkers(){ for(elem:bigList){ GeoPoint geoPoint = new GeoPoint((int)(elem.getLat()*1000000), (int) (elem.getLon()*1000000)); OverlayItem overlayItem = new OverlayItem(geoPoint, elem.getName(), elem.getData()); itemizedOverlay.addOverlay(overlayItem); mapOverlays.add(itemizedOverlay); } mapView.invalidate(); } the MyItemizedOverlay.addOverlay looks like this: public void addOverlay(OverlayItem overlay) { m_overlays.add(overlay); populate(); }

  • LicenseException for Xceed DataGrid for WPF

    - by ewall
    I have developed a simple DB-editing app using Xceed's excellent DataGrid for WPF (UX Edition version 3.7), which is now ready for deployment... except that when I run it on a machine other than the development one where it was built, I am getting the runtime exception for invalid licensing. I have included my license key in the App.xaml.cs exactly as specified in the Xceed docs, like so: public partial class App : System.Windows.Application { protected override void OnStartup(StartupEventArgs e) { Xceed.Wpf.DataGrid.Licenser.LicenseKey = "DGF37-xxxxx-xxxxx-xxxx"; base.OnStartup(e); } } The correct version of the DataGrid DLLs are being included in the setup and the application's program directory, and there are no other versions on the target machine. Debugging doesn't show me anything useful other than the LicenseException that is thrown when the code tries to use the DataGrid, with the message that reads "Xceed.Wpf.DataGrid.Licenser.LicenseKey property must be set to a valid license key in the code of your application before using this product..." Any idea what's going wrong here?

  • IEditableCollectionView.AddNew() Throwing ArgumentNullException

    - by Eugarps
    In the context of Silverlight RIA using DomainContext and, the code as follows: private void AddProductButton_Click(object sender, RoutedEventArgs e) { var target = (Web.LocatorProduct)((IEditableCollectionView)ProductSource.DataView).AddNew(); target.Locator = LocatorID; target.Product = NewProduct.Text.ToUpper(); ((IEditableCollectionView)ProductSource.DataView).CommitNew(); } Is throwing ArgumentNullException in AddNew(), CreateIdentity() further up on the stack (a generated method) due to product being null. Product and LocatorID are, in combination, the primary key. I'm guessing that EF is not allowing me to generate a new item without meeting database contraints? How does this make sense if I need to obtain a primary key from the user? I have control over all tiers of the application, so suggestions on database design if needed are also welcomed.

  • Java: exception-throwing class?

    - by HH
    I have classes DirReader and Search. The search uses DirReader. I want the search to know when DirReader throws exception. So how can I have class throwing exception? Currently, I use initCorrect -dummy var. Exception-style method may be more appropriate. Simplified Example Error $ javac ExceptionStatic.java ExceptionStatic.java:4: '{' expected public class ExceptionStatic throws Exception{ ^ 1 error Code import java.util.*; import java.io.*; // THIS PART NEEDS TO BE FIXED: public class ExceptionStatic throws Exception{ private static boolean initCorrect = false; public static String hello; static{ try{ hello = "hallo"; //some other conditionals in real code if( true) throw new Exception(); initCorrect=true; }catch(Exception e){ e.printStackTrace(); } } public static void main(String[] args){ if(initCorrect) System.out.println(hello); } }

  • NSMutableURLRequest not obeying my timeoutInterval

    - by kubi
    I'm POST'ing a small image, so i'd like the timeout interval to be short. If the image doesn't send in a few seconds, it's probably never going to send. For some unknown reason my NSURLConnection is never failing, no matter how short I set the timeoutInterval. // Create the URL request NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"http://www.tumblr.com/api/write"] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:0.00000001]; /* Populate the request, this part works fine */ [NSURLConnection connectionWithRequest:request delegate:self]; I have a breakpoint set on - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error but it's never being triggered. My images continue to be posted just fine, they're showing up on Tumblr despite the tiny timeoutInterval.

  • Freehand drawing with Quartz 2D

    - by qutaibah
    I am trying to develop a simple freehand-drawing app for red-marking some of my images. Below is a method that is called from within the drawRect. I want to ask if there is a way to avoid add the path every time the path is redrawn? Also, the way the draw method is set up, the drawing gets a bit slow and choopy after a few seconds. How can I improve the smoothness of the drawn path? thanks -(void)freehandDraw:(CGContextRef)context inRect:(CGRect)rect { CGPathAddLineToPoint( path, NULL, drawTip.x, drawTip.y); CGContextAddPath( context, path); CGContextStrokePath(context); } // method

  • Remove characters after specific character in string, then remove substring?

    - by sah302
    I feel kind of dumb posting this when this seems kind of simple and there are tons of questions on strings/characters/regex, but I couldn't find quite what I needed (except in another language: http://stackoverflow.com/questions/2176544/remove-all-text-after-certain-point). I've got the following code: [Test] public void stringManipulation() { String filename = "testpage.aspx"; String currentFullUrl = "http://localhost:2000/somefolder/myrep/test.aspx?q=qvalue"; String fullUrlWithoutQueryString = currentFullUrl.Replace("?.*", ""); String urlWithoutPageName = fullUrlWithoutQueryString.Remove(fullUrlWithoutQueryString.Length - filename.Length); String expected = "http://localhost:2000/somefolder/myrep/"; String actual = urlWithoutPageName; Assert.AreEqual(expected, actual); } I tried the solution in the question above (hoping the syntax would be the same!) but nope. I want to first remove the queryString which could be any variable length, then remove the page name, which again could be any length. How can I get the remove the query string from the full URL such that this test passes?

  • Where did my Toolbar button go?

    - by Driss Zouak
    When MyView gets pushed on to the NavigationController, I have the following code public override void ViewDidLoad () { this.NavigationController.Toolbar.SetItems(new UIBarButtonItem[] { new UIBarButtonItem("Next",UIBarButtonItemStyle.Plain, ClickNext) }, true); this.NavigationItem.Title = "Proposal Plan - Step 1"; } The Title gets set properly, and the code runs but in my Toolbar at the bottom of the view I don't have the "Next" button I am expecting. I put a breakpoint and verified that the Toolbar after running that line does have my button, but still nothing. What am I mising?

  • How do I get the SharedPreferences from a PreferenceActivity in Android?

    - by Dave
    Hi, I am using a PreferenceActivity to show some settings for my application. I am inflating the settings via a xml file so that my onCreate (and complete class methods) looks like this: public class FooActivity extends PreferenceActivity { @Override public void onCreate(Bundle icicle) { super.onCreate(icicle); addPreferencesFromResource(R.xml.preference); } } The javadoc of PreferenceActivity states, that These preferences will automatically save to SharedPreferences as the user interacts with them. To retrieve an instance of SharedPreferences that the preference hierarchy in this activity will use, call getDefaultSharedPreferences(android.content.Context) with a context in the same package as this activity. But how I get the name of the SharedPreference in another Activity? I can only call getSharedPreferences(name, mode) in the other activity but I need the name of the SharedPreference which was used by the PreferenceActivity. What is the name or how can i retrieve it?

    Consider following code which calls a calculator service: static void Main (string[] args) { for (int i = 0; i < 32; i++) { ThreadPool.QueueUserWorkItem (o => { var client = new CalcServiceClient (); client.Open (); while (true) { var sum = client.Add (2, 3); } }); } Console.ReadLine (); } If I use TCP binding then maximum 32 connections are opened but if I use HTTP binding, only 2 TCP connections are opened. How can I configure the maximum number of connections that can be opened using HTTP binding?

  • Why is my onItemSelectedListener not called in a ListView?

    - by Janusz
    I'm using a ListView that is setup like this: <ListView android:id="@android:id/list" android:layout_width="fill_parent" android:layout_height="fill_parent" android:longClickable="false" android:choiceMode="singleChoice"> </ListView> In my code I add an OnItemSelectedListener to the ListView like this: getListView().setAdapter(adapter); getListView().setOnItemSelectedListener(this); my Activity implements the listener like this: @Override public void onItemSelected(AdapterView<?> parent, View view, int position, long id) { Log.d("LocateByCategory", "ListItemSelected: Parent: " + parent.toString() + " View: " + view.toString() + " Position: " + " Id: " + id); } My hope was, that I would see this debug output the moment I click on something in the list. But the debug output is never shown in LogCat.

  • UIView drawRect; class variables out of scope

    - by Toby Wilson
    Short & sweet version of my last question in light of new information. I have a UIVIew with an init and a drawrect method (and another thread and a bunch of other stuff, but I'll keep it short & sweet). All of the class variables that I alloc and init in the -(id)init method are out of scope/nil/0x0 in the drawRect method, and I am unable to access them. For example; In the interface: NSObject* fred; In the implementation: -(id)init { if(self == [super init]) { fred = [[NSObject alloc] init]; } return self; } -(void)drawRect:(CGRect)rect { NSLog(@"Fred is retained %i times",[fred retainCount]); //FAIL NSLog(@"But his variable is actually just pointing at uninitialised 0x0, so you're not reading this in the debugger because the application has crashed before it got here." } Should add that init IS being called before drawRect also. Anyone have any ideas?

  • Objective-C (iPhone) Memory Management

    - by Steven
    I'm sorry to ask such a simple question, but it's a specific question I've not been able to find an answer for. I'm not a native objective-c programmer, so I apologise if I use any C# terms! If I define an object in test.h @interface test : something { NSString *_testString; } Then initialise it in test.m -(id)init { _testString = [[NSString alloc] initWithString:@"hello"]; } Then I understand that I would release it in dealloc, as every init should have a release -(void)dealloc { [_testString release]; } However, what I need clarification on is what happens if in init, I use one of the shortcut methods for object creation, do I still release it in dealloc? Doesn't this break the "one release for one init" rule? e.g. -(id)init { _testString = [NSString stringWithString:@"hello"]; } Thanks for your helps, and if this has been answered somewhere else, I apologise!!

  • Placement coordinates of bitmapData in AS3

    - by TheDarkIn1978
    i've programatically created a vector graphic (rect), repositioned the graphic, and set up an MOUSE_MOVE eventListener to trace color information of the graphic using getPixel(). however, the bitmapData is placed at 0,0 of the stage and i don't know how to move it so that it matches the graphic's location. var coloredSquare:Sprite = new GradientRect(200, 200, 0xFFFFFF, 0x000000, 0xFF0000, 0xFFFF00); coloredSquare.x = 100; addChild(coloredSquare); var coloredSquareBitmap:BitmapData = new BitmapData(coloredSquare.width, coloredSquare.height, true, 0); coloredSquareBitmap.draw(coloredSquare); coloredSquare.addEventListener(MouseEvent.MOUSE_MOVE, readColor); function readColor(evt:Event):void { var pixelValue:uint = coloredSquare.getPixel(mouseX, mouseY); trace(pixelValue.toString(16)); }

  • Ninject : ninject.web - How to apply on a regular ASP.Net Web (!MVC)

    - by No Body
    What I am looking is something similar to the below (http://github.com/ninject/ninject.web.mvc): README.markdown This extension allows integration between the Ninject core and ASP.NET MVC projects. To use it, just make your HttpApplication (typically in Global.asax.cs) extend NinjectHttpApplication: public class YourWebApplication : NinjectHttpApplication { public override void OnApplicationStarted() { // This is only needed in MVC1 RegisterAllControllersIn("Some.Assembly.Name"); } public override IKernel CreateKernel() { return new StandardKernel(new SomeModule(), new SomeOtherModule(), ...); // OR, to automatically load modules: var kernel = new StandardKernel(); kernel.AutoLoadModules("~/bin"); return kernel; } } Once you do this, your controllers will be activated via Ninject, meaning you can expose dependencies on their constructors (or properties, or methods) to request injections.

  • get rotation direction of UIView on touchesMoved

    - by mlecho
    this may sound funny, but i spent hours trying to recreate a knob with a realistic rotation using UIView and some trig. I achieved the goal, but now i can not figure out how to know if the knob is rotating left or right. The most pertinent part of the math is here: - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; CGPoint pt = [touch locationInView:self]; float dx = pt.x - iv.center.x; float dy = pt.y - iv.center.y; float ang = atan2(dy,dx); //do the rotation if (deltaAngle == 0.0) { deltaAngle = ang; initialTransform = iv.transform; }else { float angleDif = deltaAngle - ang; CGAffineTransform newTrans = CGAffineTransformRotate(initialTransform, -angleDif); iv.transform = newTrans; currentValue = [self goodDegrees:radiansToDegrees(angleDif)]; } } ideally, i could leverage a numeric value to tell me if the rotation is positive or negative.
