  • How can I prevent Telerik RadChart from generating an onerror attribute?

    - by Sean McMillan
    We're using the Telerik Rad Controls for ASP.Net Ajax on an ASP.Net MVC project. The RadChart generates the following HTML: <img onerror="if(confirm('Error loading RadChart image.\nYou may also wish to check the ASP.NET Trace for further details.\nDisplay stack trace?'))window.location.href=this.src;" src="ChartImage.axd?UseSession=true&amp;ChartID=e25ad666-e05b-4a92-ac0c-4f2c729b9382_chart_ctl00$MainContent$AverageCTMChart&amp;imageFormat=Png&amp;random=0.501658702968461" usemap="#imctl00_MainContent_AverageCTMChart" style="border-width: 0px;" alt=""> I'd like to remove the onerror attribute; I don't really want the customers being offered the option to see a stack trace if something goes wrong. I can't see any way to control the markup that this control generates. Google searches provide no help. Has anyone dealt with this before? How do I remove the onerror attribute?

  • EF4, MVC 3, Azure and Code First or Traditional

    - by RichardAlanA
    I am planning to build a web application using ASP MVC3 that runs on Azure with a SQL Azure back end. I would like to use the Microsoft stack and have no plans to ever change to another stack. I am looking into the use of WCF and WF but that would be in the future. I looked at the traditional and Code First approach to using Entity Framework but I can't see if there is any advantage in using one or the other approach. Sure they each have advantages but for me I don't care if my classes do inherit from EF classes. All I want is to find the most efficient solution. Can anyone out there give me some advice as to which approach might be the best. thanks very much Richard

  • Hooking a Stacktrace in Delphi 2009

    - by Jim McKeeth
    The Exception class in Delphi 2009 received a number of new features. A number of them are related to getting a stacktrace: property StackTrace: string *read* GetStackTrace; property StackInfo: Pointer read FStackInfo; class var GetExceptionStackInfoProc: function (P: PExceptionRecord): Pointer; class var GetStackInfoStringProc: function (Info: Pointer): string; class var CleanUpStackInfoProc: procedure (Info: Pointer); Has anyone used these to obtain a stack trace yet? Yeah, I know there are other ways to get a stack trace, but if it is supported natively in the Exception class I would rather leverage that. Update: There is an interest blog post about this. Covers it in a lot of depth.

  • windbg/cdb hangs when bp hit

    - by aaron
    I have a problem where cdb or windbg hangs frequently, but not all the time, when I'm debugging with it and I attach to a specific application on my machine. I found this article: http://www.nynaeve.net/?p=164 which talks about a symbol loading race condition being the problem, but I can force load the symbols, actually have a breakpoint in-app work, and still have it hang elsewhere. Here is the stack from cdb itself when I attach to it with another debugger: ntdll!NtReadFile kernel32!ReadFile cdb!ReadNonConLine cdb!ConIn cdb!MainLoop cdb!main !analyze reports that APPLICATION_HANG_BusyHang is the problem bucket, and 'ReadNonConLine' is the offending function. as far as the stack goes: ffffffff`fffffffe 00000000`00000000 00000001`3f641498 00000000`0014ea50 : kernel32!ReadFile+0x86 00000000`000002a4 00000000`0014ebb0 00000000`00001000 00000000`00000000 : cdb!ReadNonConLine+0x6d ReadNonConLine has the string "g" at 0014ebb0 passed as a param, which may be part of the command I had at the hanging breakpoint (it was something like bp foo "dt a; g") ReadFile takes a handle as its first parameter. I'm surprised by the value -2, though, that doesn't look valid. Any help is appreciated. Thanks! Aaron

  • WCF webservice stop working after upgrade to framework 3.5 sp1

    - by Victor
    I have a wcf webservice on one of my testing servers. Everything worked fine until I upgraded frome framework 3.5 to 3.5 sp1. the wcf web service stoped working and returns the error: "Failed to invoke the service. The service may be offline or inaccessible. Refer to the stack trace for details." "The remote server returned an unexpected response: (502) Proxy Error ( The specified network name is no longer available. ).

  • ClassCastException when casting custom View subclass

    - by Jens Jacob
    Hi I've run into an early problem with developing for android. I've made my own custom View (which works well). In the beginning i just added it to the layout programmatically, but i figured i could try putting it into the XML layout instead (for consistency). So what i got is this: main.xml: [...] <sailmeter.gui.CompassView android:id="@+id/compassview1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@id/widget55" android:background="@color/white" /> [...] CompassView.java: public class CompassView extends View { } SailMeter.java (activity class): public class SailMeter extends Activity implements PropertyChangeListener { public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); compassview = (CompassView) findViewById(R.id.compassview1); [...] } } (Theres obviously more, but you get the point) Now, this is the stacktrace: 05-23 16:32:01.991: ERROR/AndroidRuntime(10742): Uncaught handler: thread main exiting due to uncaught exception 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): java.lang.RuntimeException: Unable to start activity ComponentInfo{sailmeter.gui/sailmeter.gui.SailMeter}: java.lang.ClassCastException: android.view.View 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2596) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2621) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at android.app.ActivityThread.access$2200(ActivityThread.java:126) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1932) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at android.os.Handler.dispatchMessage(Handler.java:99) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at android.os.Looper.loop(Looper.java:123) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at android.app.ActivityThread.main(ActivityThread.java:4595) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at java.lang.reflect.Method.invokeNative(Native Method) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at java.lang.reflect.Method.invoke(Method.java:521) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:860) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:618) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at dalvik.system.NativeStart.main(Native Method) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): Caused by: java.lang.ClassCastException: android.view.View 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at sailmeter.gui.SailMeter.onCreate(SailMeter.java:51) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2544) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): ... 11 more Why cant i cast my custom view?

  • Android: SlidingDrawer disappears under SurfaceView

    - by ykrasik
    Hi, I'm trying to create a SlidingDrawer with LinearLayout content over a FrameLayout. At first it all seems fine, I get my SlidingDrawer's handle at the bottom of the screen. But then, if I start dragging the handle up and the content starts showing, it gets clipped by the border rectangle of the handle. If I drag the handle all the way up the entire content eventually gets shown, however if I now drag the handle down, it will be clipped by the border rectangle of the content. Also, if the handle is all the way up, as soon as I start dragging it the whole content disappears. I can still click on where the handle should be on the screen, drag it and the content would show, but I need to guess where the handle is. What seems to be causing this is the fact that I have a SurfaceView in the xml file just before SlidingDrawer. Removing the view from the xml solves this problem, however I need this view. Here's the xml: <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent"> <!-- Removing this DrawView from here solves the problem --> <com.package.DrawView android:id="@+id/main" android:layout_width="fill_parent" android:layout_height="fill_parent" /> <SlidingDrawer android:id="@+id/SlidingDrawer" android:layout_width="wrap_content" android:layout_height="wrap_content" android:allowSingleTap="true" android:animateOnClick="true" android:handle="@+id/slideHandleButton" android:content="@+id/contentLayout" android:padding="10dip"> <Button android:id="@+id/slideHandleButton" android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="@drawable/sliding_button"> </Button> <LinearLayout android:id="@+id/contentLayout" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="vertical"> <Button android:id="@+id/clearButton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Test"> </Button> </LinearLayout> </SlidingDrawer> </FrameLayout> Java: package com.package; import android.app.Activity; import android.os.Bundle; public class SlideTest extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } } package com.package; import android.content.Context; import android.util.AttributeSet; import android.view.SurfaceView; public class DrawView extends SurfaceView { public DrawView(Context context, AttributeSet attrs) { super(context, attrs); } } Edit: I just noticed that if DrawView extends View and not SurfaceView this problem goes away. However, I'm using a dedicated drawing thread and according to the documentation (and LunarLander example) when using a dedicated drawing thread, it should draw to a SurfaceView. Any help would be greatly appreciated!

    - by Oliver Goossens
    Hi, I am exploring android and developement and I found one problem.

And thats the problem - how do I POINT the setText() Method? How do I tell it to change a specified text?

How can this be done? I read something about r.IDs but I truly dont have a idea how to use them, where to find them and how to implement it .... Please advise Thank you Oliver

  • How to stop the android soft keyboard from ever coming up in my entire application

    - by JohnnyLambada
    I'm developing an application on a hardware device that has a built-in hardware keyboard that does not slide out so is always visible (like a blackberry). Therefore, I NEVER want the soft keyboard to display for my entire application. I'm aware of another SO question that gives the following lines of code: InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE); imm.hideSoftInputFromWindow(myEditText.getWindowToken(), 0); But I don't know where to put this code to hide the soft keyboard in all places where it might possibly appear in my Activity. I have tried adding the code to Activity.onUserInteraction to no avail. It seems the keyboard appears after the onUserInteraction executes.

  • Accessing Bluetooth virtual COM port on Windows without manual pairing

    - by oo_olo_oo
    I need to connect to a Bluetooth device through virtual COM port created in Windows. It's easy when the port has been already created during manual pairing procedure. But I would like my application to relieve an user from the manual pairing of a device. I would like to present all devices in the range, allow user to chose one, and then create virtual COM port connected with the selected device. I'm not trying to avoid the pairing procedure itself, but rather I would like to invoke it by my application. I started getting familiar with Microsoft Bluetooth API. And then some doubts arose. I've been wondering what happen if some user would use different (than Microsoft's) Bluetooth stack? Is the Microsoft's API the real Bluetooth API, which have to be implemented by any other Bluetooth stack provider? Or rather each provider has its own API, and the Microsoft's is only one of many other?

  • PopupWindow with GridView - Trouble with inflating view

    - by k_day
    I am having an issue while trying to use a GridView in a PopupWindow. On my Activity's onCreate method, I am inflating a gridview from xml as follows: LayoutInflater inflater = (LayoutInflater)this.getSystemService (Context.LAYOUT_INFLATER_SERVICE); final GridView popupview = (GridView) inflater.inflate (R.layout.gridviewpopup, null, false); popupview.setAdapter(new ImageAdapter(this)); would like this GridView to popup on a button click. Also inside of my activity's onCreate, I have: final Button addButton = (Button) findViewById(R.id.add); addButton.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { PopupWindow mwindow = new PopupWindow(popupview, 100, 100); mwindow.showAtLocation(findViewById(R.id.main), Gravity.CENTER, 100, 100); mwindow.setFocusable(true); } }); On button click, I am throwing a ClassCastException from GridView.onMeasure(int, int). Can anyone please explain to me what I am doing wrong?

  • NullPointerException in webview.java (android.webkit.WebView$PrivateHandler.handleMessage)

    - by PacificSky
    Every few days I get a crash report for my application with the following stack trace, or small variants thereof (with different line numbers based on different android versions) java.lang.NullPointerException at WebView.java:8241:in `android.webkit.WebView$PrivateHandler.handleMessage' Handler.java:99:in `android.os.Handler.dispatchMessage' Looper.java:150:in `android.os.Looper.loop' ActivityThread.java:4293:in `android.app.ActivityThread.main' Method.java:-2:in `java.lang.reflect.Method.invokeNative' Method.java:507:in `java.lang.reflect.Method.invoke' ZygoteInit.java:849:in `com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run' ZygoteInit.java:607:in `com.android.internal.os.ZygoteInit.main' NativeStart.java:-2:in `dalvik.system.NativeStart.main' This specific stack was on Android 2.3.4 on a HTC EVO 3D PG86100 device. My app does host several webviews for some oAuth-related login scenarios. How should I go about trying to figure out how to fix this? I've tried looking on grepcode to find the source, but I'm unable to find a matching line number that makes sense. Is my Grepcode-fu weak?

  • Beginner - C# iteration through directory to produce a file list

  • openmp in mex : stackoverflow error

    i have got the following fraction of code that getting me the stack overflow error #pragma omp parallel shared(Mo1, Mo2, sum_normalized_p_gn, Data, Mean_Out,Covar_Out,Prior_Out, det) private(i) num_threads( number_threads ) { //every thread has a new copy double* normalized_p_gn = (double*)malloc(NMIX*sizeof(double)); #pragma omp critical { int id = omp_get_thread_num(); int threads = omp_get_num_threads(); mexEvalString("drawnow"); } #pragma omp for //some parallel process..... } the variables declared in the shared are created by malloc. and they consumes with large amount of memory there are 2 questions regarding to the above code. 1) why this would generate the stack overflow error( i.e. segmentation fault) before it goes into the parallel for loop? it works fine when it runs in the sequential mode.... 2) am i right to dynamic allocate memory for each thread like "normalized_p_gn" above?

  • JRuby Slick CanvasGameContainer using too much heap memory

    - by Jwosty
    I'm using Java's Slick library (great, by the way) just fine from JRuby. To start a game, I use AppGameContainer which works completely fine and as expected, but if I try to use CanvasGameContainer instead (I want a resizable window and Slick uses an old version of LWJGL that doesn't support this directly) it throws this error: Fri Jun 01 10:22:07 MDT 2012 INFO:Slick Build #274 Error: Your application used more stack memory than the safety cap of 2048K. Specify -J-Xss####k to increase it (#### = cap size in KB). Specify -w for full StackOverflowError stack trace I've tried increasing the heap size until my computer can't allocate any more memory, but to no avail. The CanvasGameContainer uses an awt window to display, which is resizable. Any ideas on why this is happening and/or how to fix this?

  • Java: why is declaration not sufficient in interface?

    - by HH
    Big class contains Format-interfcase and Format-class. The Format-class contains the methods and the interface has the values of the fields. I could have the fields in the class Format but the goal is with Interface. So do I just create dummy-vars to get the errors away, design issue or something ELSE? KEY: Declaration VS Initialisation Explain by the terms, why you have to init in interface. What is the logic behind it? To which kind of problems it leads the use of interface? Sample Code having the init-interface-problem import java.util.*; import java.io.*; public class FormatBig { private static class Format implements Format { private static long getSize(File f){return f.length();} private static long getTime(File f){return f.lastModified();} private static boolean isFile(File f){if(f.isFile()){return true;}} private static boolean isBinary(File f){return Match.isBinary(f);} private static char getType(File f){return Match.getTypes(f);} private static String getPath(File f){return getNoErrPath(f);} //Java API: isHidden, --- SYSTEM DEPENDED: toURI, toURL Format(File f) { // PUZZLE 0: would Stack<Object> be easier? size=getSize(f); time=getTime(f); isfile=isFile(f); isBinary=isBinary(f); type=getType(f); path=getPath(f); //PUZZLE 1: how can simplify the assignment? values.push(size); values.push(time); values.push(isfile); values.push(isBinary); values.push(type); values.push(path); } } public static String getNoErrPath(File f) { try{return f.getCanonicalPath(); }catch(Exception e){e.printStackTrace();} } public static final interface Format { //ERR: IT REQUIRES "=" public long size; public long time; public boolean isFile=true; //ERROR goes away if I initialise wit DUMMY public boolean isBinary; public char type; public String path; Stack<Object> values=new Stack<Object>(); } public static void main(String[] args) { Format fm=new Format(new File(".")); for(Object o:values){System.out.println(o);} } }

  • UITabBarController With UINavigationController "more" Tab Issue

    - by Medlay
    UITabBarController with UINavigationController "more" tab issue There is a problem with using UINavigationController in UITabBarController. I have a TabBar  with 6 items. Of course, a standart item "more" appears, and there are two UINavigationControllers that didn't fit in a TabBar. The core of the problem is: when I'm working with visible items (a first four), UIViewController can be pushed  in an UINavigationController: [self.navigationController pushViewController:userDataViewController animated:YES]; If you call on in "more" and rearrange items in such way, that a visible UINavigationController gets into "more", when calling on it userDataViewController appears.  This  userDataViewController is the last, which has got in a stack and a Back button leads back to "more", but not to the controllers, that were before a userDataViewController appeared. I understand that in fact a selector pushViewController is called from "more", and it pushes my UINavigationController in a stack, and it's not good. Maybe, someone has faced such problem and could help me to solve it? Thank you forward.

  • Resetting or refreshing a database connection

    - by cdonner
    This Android application on Google uses the following method to refresh the database after replacing the database file with a backup: public void resetDbConnection() { this.cleanup(); this.db = SQLiteDatabase.openDatabase( "/data/data/com.totsp.bookworm/databases/bookworm.db", null, SQLiteDatabase.OPEN_READWRITE); } I did not build this app, and I am not sure what happens. I am trying to make this idea work in my own application, but the data appears to be cached by the views, and the app continues to show data from the database that was replaced, even after I call cleanup() and reopen the database. I have to terminate and restart the activity in order to see the new data. I tried to call invalidate on my TabHost view, which pretty much contains everything. I thought that the views would redraw and refresh their underlying data, but this did also not have the expected result. I ended up restarting the activity programmatically, which works, but this seems to be a drastic measure. Is there a better way?

  • Multiple Facebook Like buttons (different activities) on one page?

    - by Larry K
    Hello, My one web page uses Ajax to display information about multiple activities. I'd like to have one Like button per activity. This would mean multiple Like buttons on the page, one per activity. Can this be done? Can the Like button's url include #!state1 ? Eg, a web page is located at www.example.com/index.html It has multiple FB Like buttons on it, one for url www.example.com/index.html#!activity1 another for www.example.com/index.html#!activity2 Will the two Like buttons work independently?
