  • Kendo UI Combo Box Reset Value

    - by ciantrius
    I'm using the Kendo UI ComboBoxes in cascade mode to build up a filter that I wish to apply. How do I clear/reset the value of a Kendo UI ComboBox? I've tried: $("#comboBox").data("kendoComboBox").val(''); $("#comboBox").data("kendoComboBox").select(''); $("#comboBox").data("kendoComboBox").select(null); all to no avail. The project is an MVC4 app using the Razor engine and the code is basically the same as the Kendo UI example.

  • C# How to unsubscribe all event handlers from a given event?

    - by Adi Barda
    Hi Guys, Is there a simple way to iterate all over the handlers subscribed to a given event? my problem is that clients subscribe but forget to unsubscribe so a memory leak happens. I need a way for an object to disconnect all the handlers of its events in the Dispose method so a leak would not happen - at least not because of events. Hope my question was clear thank you, Adi Barda

  • Pyglet OpenGL drawing anti-aliasing

    - by Jared Forsyth
    I've been looking around for a way to anti-alias lines in OpenGL, but none of them seem to work... here's some example code: import pyglet from pyglet.gl import * window = pyglet.window.Window(resizable=True) @window.event def on_draw(): window.clear() pyglet.gl.glColor4f(1.0,0,0,1.0) glBlendFunc (GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA) glEnable (GL_BLEND) glEnable (GL_LINE_SMOOTH); glHint (GL_LINE_SMOOTH_HINT, GL_DONT_CARE) glLineWidth (3) pyglet.graphics.draw(2, pyglet.gl.GL_LINES, ('v2i', (10, 15, 300, 305)) ) pyglet.app.run() Can anyone see what I am doing wrong?

  • How to solve QPixmap::fromImage memory leak?

    - by dodoent
    Hello everyone! I have a problem with Qt. Here is a part of code that troubles me: void FullScreenImage::QImageIplImageCvt(IplImage *input) { help=cvCreateImage(cvGetSize(input), input->depth, input->nChannels); cvCvtColor(input, help, CV_BGR2RGB); QImage tmp((uchar *)help->imageData, help->width, help->height, help->widthStep, QImage::Format_RGB888); this->setPixmap(QPixmap::fromImage(tmp).scaled(this->size(), Qt::IgnoreAspectRatio, Qt::SmoothTransformation)); cvReleaseImage(&help); } void FullScreenImage::hideOnScreen() { this->hide(); this->clear(); } void FullScreenImage::showOnScreen(IplImage *slika, int delay) { QImageIplImageCvt(slika); this->showFullScreen(); if(delay>0) QTimer::singleShot(delay*1000, this, SLOT(hideOnScreen())); } So, the method showOnScreen uses private method QImageIplImageCvt to create QImage from IplImage (which is used by the openCV), which is then used to create QPixmap in order to show the image in full screen. FullScreenImage class inherits QLabel. After some delay, the fullscreen picture should be hidden, so I use QTimer to trigger an event after some delay. The event handler is the hideOnScreen method which hides the label and should clear the memory. The problem is the following: Whenever I call QPixmap::fromImage, it allocates the memory for the pixmap data and copies the data from QImage memory buffer to the QPixmap memory buffer. After the label is hidden, the QPixmap data still remains allocated, and even worse, after the new QPixmap::fromImage call the new chunk of memory is allocated for the new picture, and the old data is not freed from memory. This causes a memory leak (cca 10 MB per method call with my testing pictures). How can I solve that leak? I've even tried to create a private QPixmap variable, store pixmap created by the QPixmap::fromImage to it, and then tried to call its destructor in hideOnScreen method, but it didn't help. Is there a non-static way to create QPixmap from QImage? Or even better, is there a way to create QPixmap directly from IplImage* ? Thank you in advance for your answers.

  • Sending a Tuple object over WCF?

    - by Donut
    Is the System.Tuple class supported by WCF's Data Contract Serializer (i.e., can I pass Tuple objects to WCF calls and/or receive them as part or all of the result)? I found this page, but not the clear, definitive "you can send and receive Tuples with WCF" answer I was hoping for. I'm guessing that you can, as long as all of the types within the Tuple itself are supported by the Data Contract Serializer -- can anyone provide me with a more definitive answer? Thanks.

  • EPPlus - .xlsx is locked for editing by 'another user'

    - by AdamTheITMan
    I have searched through every possible answer on SO for a solution, but nothing has worked. I am basically creating an excel file from a database and sending the results to the response stream using EPPlus(OpenXML).

    - by nharry
    Hi all, I am using jcarousel to auto scroll some images. I would like to know how to make them scroll in one fluid scroll with no pauses or stops.

  • Custom RoleProvider with MVC 2.0 webconfig

    - by Farrell
    I have a custom MembershipProvider and a custom RoleProvider. I created the custom MembershipProvider by creating a SimpleMembershipProvider class which implements the MembershipProvider class. After that I changed my web.config and works. So I used the same approach creating a custom RoleProvider. Nothing special, just creating a SimpleRoleProvider class which implements the RoleProvider class. But then when I changed the web.config file and runs the solution I get the following error message: Web.Config <membership defaultProvider="DashboardMembershipProvider"> <providers> <clear/> <add name="SimpleMembershipProvider" type="Dashboard.Web.Controlling.Account.SimpleMembershipProvider" /> </providers> </membership> <roleManager enabled="true" defaultProvider="DashboardRoleProvider"> <providers> <clear/> <add name="DashboardRoleProvider" type="Dashboard.Web.Controlling.Account.DashboardRoleProvider" /> </providers> </roleManager> Configuration Error Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately. Parser Error Message: No parameterless constructor defined for this object. Source Error Line 78: <add name="SimpleRoleProvider" Line 79: type="Dashboard.Web.Controlling.Account.SimpleRoleProvider" /> So I searched the web. And tried on the type attribute, which generates the following errors: Configuration Error Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately. Parser Error Message: Could not load file or assembly 'Dashboard.Web.Controlling.Account' or one of its dependencies. The system cannot find the file specified. Source Error: Line 78: <add name="SimpleRoleProvider" Line 79: type="Dashboard.Web.Controlling.Account.SimpleRoleProvider,Dashboard.Web.Controlling.Account" /> Any suggestions on how I would be able to get this CustomRoleProvider working? Any help is greatly appreciated!

  • Can I use Microsoft Chart Control in Mono?

    Did some googling and couldn't find a clear answer on this. My assumption is no if they are distributed in a binary form. I currently use Dundas and would like to move away from a library that has a cost component, especially since the MS version has everything I need.

  • How To Find Out If You are Using HTTPS Without $_SERVER['HTTPS']

    - by Chacha102
    I've seen many tutorials online that says you need to check $_SERVER['HTTPS'] if the server is connection is secured with HTTPS. My problem is that on some of the servers I use, $_SERVER['HTTPS'] is an undefined variable that results in an error. Is there another variable I can check that should always be defined? Just to be clear, I am currently using this code to resolve if it is an HTTPS connection: if(isset($_SERVER['HTTPS'])) { if ($_SERVER["HTTPS"] == "on") { $secure_connection = true; } }

    Does anyone have a simple example of implementing an async validation rule in csla? I have looked at the example in the Company class in the Rolodex sample but this isn't particularly clear to me: why do I need a command class? I'm using csla 3.8 in a WPF application.

  • [GWT2] UiBinder work with ToggleButton

    - by EnToutCas
    I'm liking the new GWT2 UiBinder, however, it's not clear whether certain things are achievable using the declarative UI style. For instance, ToggleButton only takes the image instances at construction time (no setters for up/down images). As I understand, UiBinder works in a JavaBean-like reflective way, where the assignable attributes are mapped to corresponding setters. Is this style possible with widgets like ToggleButton, where certain attributes have to be specified at construction time? <g:ToggleButton ui:field="myBtn"></g:ToggleButton>

  • How to make non-blurry image in WPF 3d

    - by terenf
    I used Viewport3D and ModelVisual3D to create a simple rectangle with an image (I tried it with JPG, PNG), but it shows the image blurry, but the original image is very sharp and clear. I don't know how to make it with the original quality in 3D... I also tried some 2D solutions like RenderOptions.BitmapScalingMode and SnapsToDevicePixels but they do not seem to not work in the 3D case. Has anyone encountered this problem or know the solution?

  • iPhone SDK Zoom and refresh PDF with Quartz

    - by Ben
    Looking at the QuartzDemo sample application, I love the speed of the PDF rending using quartz alone (that is, without using uiwebview). However, when I'm zooming in the PDF it doesn't seem to become more clear like it does in PDF view. Is there something that I can change to have the same effect when zooming in and out using multitouch? like manipulate the PDF transformation matrix or something? Thanks a bunch. --Ben

  • Where to stop/destroy threads in Android Service class?

    - by niko
    Hi, I have created a threaded service the following way: public class TCPClientService extends Service{ ... @Override public void onCreate() { ... Measurements = new LinkedList<String>(); enableDataSending(); } @Override public IBinder onBind(Intent intent) { //TODO: Replace with service binding implementation return null; } @Override public void onLowMemory() { Measurements.clear(); super.onLowMemory(); }; @Override public void onDestroy() { Measurements.clear(); super.onDestroy(); try { SendDataThread.stop(); } catch(Exception e) { } }; private Runnable backgrounSendData = new Runnable() { public void run() { doSendData(); } }; private void enableDataSending() { SendDataThread = new Thread(null, backgrounSendData, "send_data"); SendDataThread.start(); } private void addMeasurementToQueue() { if(Measurements.size() <= 100) { String measurement = packData(); Measurements.add(measurement); } } private void doSendData() { while(true) { try { if(Measurements.isEmpty()) { Thread.sleep(1000); continue; } //Log.d("TCP", "C: Connecting..."); Socket socket = new Socket(); socket.setTcpNoDelay(true); socket.connect(new InetSocketAddress(serverAddress, portNumber), 3000); //socket.connect(new InetSocketAddress(serverAddress, portNumber)); if(!socket.isConnected()) { throw new Exception("Server Unavailable!"); } try { //Log.d("TCP", "C: Sending: '" + message + "'"); PrintWriter out = new PrintWriter( new BufferedWriter( new OutputStreamWriter(socket.getOutputStream())),true); String message = Measurements.remove(); out.println(message); Thread.sleep(200); Log.d("TCP", "C: Sent."); Log.d("TCP", "C: Done."); connectionAvailable = true; } catch(Exception e) { Log.e("TCP", "S: Error", e); connectionAvailable = false; } finally { socket.close(); announceNetworkAvailability(connectionAvailable); } } catch (Exception e) { Log.e("TCP", "C: Error", e); connectionAvailable = false; announceNetworkAvailability(connectionAvailable); } } } } After I close the application the phone works really slow and I guess it is due to thread termination failure. Does anyone know what is the best way to terminate all threads before terminating the application?

  • How can I define a clojure type that implements the servlet interface?

    - by Rob Lachlan
    I'm attempting to use deftype (from the bleeding-edge clojure 1.2 branch) to create a java class that implements the java Servlet interface. I would expect the code below to compile (even though it's not very useful). (ns foo [:import [javax.servlet Servlet ServletRequest ServletResponse]]) (deftype servlet [] javax.servlet.Servlet (service [this #^javax.servlet.ServletRequest request #^javax.servlet.ServletResponse response] nil)) But it doesn't compile. The compiler produces the message: Mismatched return type: service, expected: void, had: java.lang.Object [Thrown class java.lang.IllegalArgumentException] Which doesn't make sense to me, because I'm returning nil. So the fact that the return type of the method is void shouldn't be a problem. For instance, for the java.util.Set interface: (deftype bar [#^Number n] java.util.Set (clear [this] nil)) compiles without issue. So what am I doing wrong with the Servlet interface? To be clear: I know that the typical case is to subclass one of the servlet abstract classes rather than implement this interface directly, but it should still be possible to do this. Stack Trace: The stack trace for the (deftype servlet... is: Mismatched return type: service, expected: void, had: java.lang.Object [Thrown class java.lang.IllegalArgumentException] Restarts: 0: [ABORT] Return to SLIME's top level.

  • Casting from IEnumerable<Object> to IEnumerable<string>

    - by Praveen
    Hi All, Recently I found a very surprising behavior in c#. I had a method which takes IEnumerable<Object> as a parameter and i was passing IEnumerable<string> but it's not possible. While in c# everything can be upcast to Object than why this is not possible? It's totally confusing for me. Please someone clear me on this issue.
