  • Why doesn't Visual Studio show an exception message when my exception occurs in a static constructor

    - by Tim Goodman
    I'm running this C# code in Visual Studio in debug mode: public class MyHandlerFactory : IHttpHandlerFactory { private static Dictionary<string, bool> myDictionary = new Dictionary<string, bool>(); static MyHandlerFactory() { myDictionary.Add("someKey",true); myDictionary.Add("someKey",true); // fails due to duplicate key } } Outside of the static constructor, when I get to the line with the error Visual Studio highlights it and pops up a message about the exception. But in the static constructor I get no such message. I am stepping through line-by-line, so I know that I'm getting to that line and no further. Why is this? (I have no idea if that fact that my class implements IHttpHandlerFactory matters, but I included it just in case.) This is VS2005, .Net 2.0

  • ProgressBar not updating on change to Maximum through binding

    - by Tom
    <ProgressBar Foreground="Red" Background="Transparent" Value="{Binding NumFailed, Mode=OneWay}" Minimum="0" Maximum="{Binding NumTubes, Mode=OneWay, Converter={x:Static wpftools:DebuggingConverter.Instance}, ConverterParameter=Failedprogressbar}" FlowDirection="RightToLeft" Style="{DynamicResource {x:Static wpftools:CustomResources.StyleProgressBarVistaKey}}" /> This is what my progressbar looks like at the moment. The style came from http://mattserbinski.com/blog/look-and-feel-progressbar and the DebuggingConverter is a no-op converter that prints the value, type and parameter to the Console. I have verified that the converter for the Maximum is being called when my NumTubes property is changed. Basically, the ProgressBar won't redraw until the Value changes. So, if I have 2 tubes and 1 is failed, even if I add 20 more tubes, the bar is still half filled until the NumFailed changes, then the proportion is updated. I've tried adding spurious notifications of the NumFailed property, but that apparently doesn't work since the value didn't change. Ideas?

  • Static analysis tool customization for any language

    - by Sam
    Hi, We are using a Tool in our project. This tool has its own language which is similar to Java. I am looking for a static analysis tool which can be applied to the new language. Are there any static analysis tools which can be customized to any languages? or Is there any document or any reference on how to develop the static analysis tool for our own languages? Thanks.

  • Why static fields are not initialized in time?

    - by Tom Brito
    Somebody tell me: class MyClass { private static MyClass myClass = new MyClass(); private static final Object obj = new Object(); public MyClass() { System.out.println(obj); // will print null once } } I wonder, isn't this a bug? Why static objects are not initialized before the constructor runs?

  • Best Static Website Generator

    - by Nick Retallack
    In the age of dynamic websites built with layouts and templates, nobody wants to write plain old repetitive static html anymore. But now that you can outsource dynamic features to services like Disqus, and you could get slashdotted/dugg/reddited at any moment, sometimes a static website is best for scalability. There are quite a few static website generators out there that let you use templates, layouts, alternative markup languages, and other new age stuff. So this question is a bit of a survey. Which do you think is the best, and why? Here are a few examples to start us off: WebGen StaticMatic Static

  • WPF, getting two way binding to work on custom control

    - by e28Makaveli
    Two way binding does not work on my custom control with the following internals: public partial class ColorInputControl { public ColorInputControl() { InitializeComponent(); colorPicker.AddHandler(ColorPicker.SelectedColorChangedEvent, new RoutedPropertyChangedEventHandler( SelectedColorChanged));; colorPicker.AddHandler(ColorPicker.CancelEvent, new RoutedPropertyChangedEventHandler(OnCancel)); } public static readonly DependencyProperty SelectedColorProperty = DependencyProperty.Register ("SelectedColor", typeof(Color), typeof(ColorInputControl), new PropertyMetadata(Colors.Transparent, null)); public Color SelectedColor { get { return (Color)GetValue(SelectedColorProperty); //return colorPicker.SelectedColor; } set { SetValue(SelectedColorProperty, value); colorPicker.SelectedColor = value; } } private void SelectedColorChanged(object sender, RoutedPropertyChangedEventArgs<Color> e) { SetValue(SelectedColorProperty, colorPicker.SelectedColor); } } SelectedColor is being bound to a property that fires INotifyPropertyChanged event control when it changes. However, I cannot get two way binding to work. Changes from the UI are pesisted to the data source. However, changes originating from the data source are not reflected on the UI. What did I miss? TIA.

  • Monotouch Binding to Linea Pro SDK

    - by jeffrapp
    I'm trying to create a binding to the Linea Pro (it's the barcode scanner they use in the Apple Stores, Lowes) SDK. I'm using David Sandor's bindings as a reference, but the SDK has been updated a few times since January of 2011. I have most everything working, except for the playSound call, which is used to, well, play a sound on the Linea Pro device. The .h file from the SDK has the call as follows: -(BOOL)playSound:(int)volume beepData:(int *)data length:(int)length error:(NSError **)error; I've tried using int[], NSArray, and an IntPtr to the int[], but nothing seems to work. The last unsuccessful iteration of my binding looks like: [Export ("playSound:beepData:length:")] void PlaySound (int volume, NSArray data, int length); Now, this doesn't work at all. Also note that I have no idea what to do with the error:(NSError **)error part, either. I am lacking some serious familiarity with C, so any help would be extremely appreciated.

  • Is it safe to lock a static variable in a non-static class?

    - by Dario Solera
    I've got a class that manages a shared resource. Now, since access to the resource depends on many parameters, this class is instantiated and disposed several times during the normal execution of the program. The shared resource does not support concurrency, so some kind of locking is needed. The first thing that came into my mind is having a static instance in the class, and acquire locks on it, like this: // This thing is static! static readonly object MyLock = new object(); // This thing is NOT static! MyResource _resource = ...; public DoSomeWork() { lock(MyLock) { _resource.Access(); } } Does that make sense, or would you use another approach?

  • Binding list of objects to WPF ListView

    - by Dave Colwell
    Hi all, I have a list of objects which i want to bind to a ListView control in my WPF application. The Objects have a DataTemplate already, so no need to define that. The list of objects is a property in the codebehind file in the format list<object> When i add one object programatically, it appears fine. But when i try to bind the ItemSource of the ListBox to the list of objects, nothing shows up. I am using the following binding: ItemsSource="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}, Path=Portfolios}" where the name of the property i am trying to bind to is Portfolios and exists on the parent window

  • Binding using ElementName for a control within the Grid\ListView

    - by i2nfo
    Hi I am currently busy with a WPF application that uses a "GridView". There are several template columns one of which is a ComboBox in column 3 named cmbInputControlType. What I would like to do using my Converter class, which I have already created, is binding the visibility of the TextBox(txtFrom) in column 4 to the selected value of the ComboBox(Column 3). Basically if you select a value from the the ComboBox(cmbInputControlType - column 3), it must update teh visibility of the TextBox(txtFrom - column 4) <ListView Height="150" ScrollViewer.HorizontalScrollBarVisibility="Auto" ScrollViewer.VerticalScrollBarVisibility="Auto" Width="435" HorizontalAlignment="Center" Margin="5,0,5,5" Name="lstInput" VerticalAlignment="Top" SelectionMode="Single" HorizontalContentAlignment="Left"> <ListView.Resources> <local:InputControlTypeConverter x:Key="InputConType" /> </ListView.Resources> <ListView.View> <GridView> <!--Column 1--> <GridViewColumn Header="ParameterName" x:Name="lblParameterName" DisplayMemberBinding="{Binding ParameterName}" Width="100" /> <!--Column 2--> <GridViewColumn Header="DisplayName"> <GridViewColumn.CellTemplate> <DataTemplate> <TextBox x:Name="txtDisplayName" Width="150" /> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> <!--Column 3--> <GridViewColumn Header="ControlType"> <GridViewColumn.CellTemplate> <DataTemplate> <ComboBox x:Name="cmbInputControlType" Width="100" SelectionChanged="cmbInputControlType_SelectionChanged" > <ComboBoxItem Content="TextBox" /> <ComboBoxItem Content="Copy" /> </ComboBox> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> <!--Column 4--> <GridViewColumn Header="From"> <GridViewColumn.CellTemplate> <DataTemplate> <TextBox x:Name="txtCopyFrom" Width="150" Visibility="{Binding ElementName=cmbInputControlType,Path=SelectedItem, Converter={StaticResource InputConType}}" /> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> <!--Column 5--> <GridViewColumn Header="To"> <GridViewColumn.CellTemplate> <DataTemplate> <TextBox x:Name="txtCopyTo" Width="150" /> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> </GridView> </ListView.View> </ListView>

  • Advantage of using a static member function instead of an equivalent non-static member function?

    - by jonathanasdf
    I was wondering whether there's any advantages to using a static member function when there is a non-static equivalent. Will it result in faster execution (because of not having to care about all of the member variables), or maybe less use of memory (because of not being included in all instances)? Basically, the function I'm looking at is an utility function to rotate an integer array representing pixel colours an arbitrary number of degrees around an arbitrary centre point. It is placed in my abstract Bullet base class, since only the bullets will be using it and I didn't want the overhead of calling it in some utility class. It's a bit too long and used in every single derived bullet class, making it probably not a good idea to inline. How would you suggest I define this function? As a static member function of Bullet, of a non-static member function of Bullet, or maybe not as a member of Bullet but defined outside of the class in Bullet.h? What are the advantages and disadvantages of each?

  • Objective-C categories in static library

    - by Vladimir
    Can you guide me how to properly link static library to iphone project. I use staic library project added to app project as direct dependency (target - general - direct dependecies) and all works OK, but categories. A category defined in static library is not working in app. So my question is how to add static library with some categories into other project? And in general, what is best practice to use in app project code from other projects?

  • Linking error while using Qt static built libraries

    - by Kamran Amini
    I hope this is not a duplicate. Recently I'm developing a native C++ application using Qt 4.8.3 and VS2008. Since clients run the application on their naked machines, they need to install VC++ 2008 Redistribution package. So I decided to make it statically linked. I changed my project settings (C/C++ Code Generation Runtime Library) to /MTd. Also I compiled Qt again, this time using following commands for a static building; originally found on this blog Static Qt with static CRT (VS 2008) 1- replaced -MD with -MT in lines QMAKE_CFLAGS_RELEASE and QMAKE_CFLAGS_DEBUG in %QDIR%\mkspecs\win32-msvc2008\qmake.conf 2- nmake confclean 3- configure -static -platform win32-msvc2008 -no-webkit 4- nmake sub-src I compiled Qt successfully. But when I tried again to compile my application, it gave me some strange errors. 1>Linking... 1>qtmaind.lib(qtmain_win.obj) : error LNK2005: "public: bool __thiscall QBasicAtomicInt::deref(void)" (?deref@QBasicAtomicInt@@QAE_NXZ) already defined in QtCored4.lib(QtCored4.dll) 1>qtmaind.lib(qtmain_win.obj) : error LNK2005: "public: bool __thiscall QBasicAtomicInt::operator!=(int)const " (??9QBasicAtomicInt@@QBE_NH@Z) already defined in QtCored4.lib(QtCored4.dll) 1>qtmaind.lib(qtmain_win.obj) : error LNK2005: "public: __thiscall QString::~QString(void)" (??1QString@@QAE@XZ) already defined in QtCored4.lib(QtCored4.dll) I changed some lib files but with each change, situation got worse; for example I tried to use QtCored.lib instead of QtCored4.lib because it is newly created after compilation. I think I've missed something in building static Qt libs. Thanks.

  • Why can't I inherit static classes?

    - by User
    I have several classes that do not really need any state. From the organizational point of view, I would like to put them into hierarchy. But it seems I can't declare inheritance for static classes. Something like that: public static class Base { } public static class Inherited : Base { } will not work. Why have the designers of the language closed that possibility?

  • WPF ListView.CurrentChanged too fast for binding

    - by matt
    My case: MVVM ListView+Details(custom UserControl) List bound to MV.Items (IsSynchronizedWithCurrent=true) Details bound to MV.Items.Current MV.Items.Count == 100 about 0.2sec to read details (lazy mode) When I hold the down arrow on the list, very strange things happen: list items order change current changes in the random order CPU usage drastically increments and eventually all hangs. I've read some post that one should start the timer or run handler in the background, but I am not able to do that, since all the binding WPF does for me. Is there some way to instruct the binding in my DetailsControl, to wait a while before accepting CurrentItem? Or should I just resign from the clean solution and write custom code in my MV to handle that?

  • Static variables in Java for a test oObject creator

    - by stevebot
    Hey, I have something like the following TestObjectCreator{ private static Person person; private static Company company; static { person = new Person() person.setName("Joe"); company = new Company(); company.setName("Apple"); } public Person createTestPerson(){ return person; } public Person createTestCompany(){ return company; } } By applying static{} what am I gaining? I assume the objects are singletons as a result. However, if I did the following: Person person = TestObjectCreator.createTestPerson(); person.setName("Jill"); Person person2 = TestObjectCreator.createTestPerson(); would person2 be named Jill or Joe?

  • javascript binding

    MyObj = { ajax: null, init: function() { this.ajax = Cc["@mozilla.org/xmlextras/xmlhttprequest;1"].createInstance(); this.ajax.onload = function() { return function() {this.onload.apply(this, [null]);} }; }, onload: function () { Reader.log("I really hope I can use `this.ajax` here"); } } isn't it correct way to bind onload to MyObj? For some reason onload never called. However if I avoid binding and just put this.ajax.onload = this.onload then onload invoked. How to get binding work?

  • Static library woes in iPhone 3.x with categories and C libraries

    - by hgpc
    I have a static library (let's call it S) that uses a category (NSData+Base64 from MGTwitterEngine) and a C library (MiniZip wrapped by ZipArchive). This static library is used in an iPhone 3.x project (let's call it A). To be able to use the MiniZip library I included its files in project A as well as the static library S. If not I get compilation errors. Project A works fine on the simulator. When I run it on the device, I get unrecognized selector errors when the category is used. As pointed out here, it seems there's a linker bug that affects categories in iPhone 3.x (http://stackoverflow.com/questions/1147676/categories-in-static-library-for-iphone-device-3-0). The workaround is to add -all_load to the Other Linker Flags of the project that references the static library. However, if I do this then I get duplicate symbol errors because I included the MiniZip libraries in project A. A workaround is to include the category files in project A as well. If I do this, project A works well in the device, but fails to build on the simulator because of duplicate symbol errors. How should I set up project A to make it work on the simulator and the device with the same configuration?

  • Where to put constant strings in C++: static class members or anonymous namespaces

    - by stone
    I need to define some constant strings that will be used only by one class. It looks like I have three options: Embed the strings directly into locations where they are used. Define them as private static constant members of the class: //A.h class A { private: static const std::string f1; static const std::string f2; static const std::string f3; }; //A.cpp const std::string f1 = "filename1"; const std::string f2 = "filename2"; const std::string f3 = "filename3"; //strings are used in this file Define them in an anonymous namespace in the cpp file: //A.cpp namespace { const std::string f1 = "filename1"; const std::string f2 = "filename2"; const std::string f3 = "filename3"; } //strings are used in this file Given these options, which one would you recommend and why? Thanks.
