  • web.config, configSource, and "The 'xxx' element is not declared" warning.

    - by UpTheCreek
    I have broken down the horribly unwieldy web.config file into individual files for some of the sections (e.g. connectionStrings, authentication, pages etc.) using the configSource attribute. This is working file, but the individual xml files that hold the section 'snippets' cause warnings in VS. For example, a file named roleManager.config is used for the role manager section, and looks like this: <roleManager enabled="false"> </rolemanager> However I get a blue squiggle under the roleManager element in VS, and the following warning: The 'roleManager' element is not declared I guess this is something to do with valid xml and schemas etc. Is there an easy way to fix this? Something I can add to the individual files? Thanks P.S. I have heard that it is bad practice to break the web.config file out like this. But don't really understand why - can anyone illuminate me?

  • How to make an IDisposable object a class variable?

    - by Ben Aston
    I am working with Active Directory using C#. Instantiating the PrincipalContext object seems to be expensive, so I'd like to store one in a class variable. When using PrincipalContext as a local variable, I can use the convenient using syntax. When storing an IDisposable object in a static variable, how do I ensure the object is properly disposed of?

  • How to query the like count of a facebook object such as a album or photo via fql?

    - by hip10
    Hi, Here is a tricky question, how do you get the like count of a facebook object such as an album or a photo? I know that facebook has a fql table called link_stat that allow you to get the like count for an external url, but it does not seem to work if the object is within facebook. If you access the likes via the opengraph api on a particular object, it will only return a maximum of 4 users that like the object, even though there maybe a few thousand users that like it. Any clues?

  • Prism Commands - binding error when binding to list element ?

    - by Maciek
    I've got a ItemsControl (to be replaced by listbox) which has it's ItemsSource bound to an ObservableCollection<User> which is located in the view model. The View Model contains some DelegateCommand<T> delegates for handling commands (for instance UpdateUserCommand and RemoveUserCommand). All works fine if the buttons linked to those commands are placed outside of the DataTemplate of the control which is presenting the items. <ItemsControl ItemsSource="{Binding Users, Mode=TwoWay}" HorizontalContentAlignment="Stretch"> <ItemsControl.ItemTemplate> <DataTemplate> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="0.2*"/> <ColumnDefinition Width="0.2*"/> <ColumnDefinition Width="0.2*"/> <ColumnDefinition Width="0.2*"/> <ColumnDefinition Width="0.2*"/> </Grid.ColumnDefinitions> <TextBlock Grid.Column="0" Text="{Binding UserName}"/> <PasswordBox Grid.Column="1" Password="{Binding UserPass}"/> <TextBox Grid.Column="2" Text="{Binding UserTypeId}"/> <Button Grid.Column="3" Content="Update" cal:Click.Command="{Binding UpdateUserCommand}" cal:Click.CommandParameter="{Binding}"/> <Button Grid.Column="4" Content="Remove" cal:Click.Command="{Binding RemoveUserCommand}" cal:Click.CommandParameter="{Binding}"/> </Grid> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> What I'm trying to achieve, is : Have each row - generated by the ListView/ItemsControl - contain buttons to manage the item represented that particular row. During the runtime, the VS's output panel generated the following messages for each listbox element System.Windows.Data Error: BindingExpression path error: 'UpdateUserCommand' property not found on 'ModuleAdmin.Services.User' 'ModuleAdmin.Services.User' (HashCode=35912612). BindingExpression: Path='UpdateUserCommand' DataItem='ModuleAdmin.Services.User' (HashCode=35912612); target element is 'System.Windows.Controls.Button' (Name=''); target property is 'Command' (type 'System.Windows.Input.ICommand').. System.Windows.Data Error: BindingExpression path error: 'RemoveUserCommand' property not found on 'ModuleAdmin.Services.User' 'ModuleAdmin.Services.User' (HashCode=35912612). BindingExpression: Path='RemoveUserCommand' DataItem='ModuleAdmin.Services.User' (HashCode=35912612); target element is 'System.Windows.Controls.Button' (Name=''); target property is 'Command' (type 'System.Windows.Input.ICommand').. Which would imply that there are binding errors present. Is there any way to make this right? or is this not the way?

  • DTO or Domain Model Object in the View Layer?

    - by smayers81
    I know this is probably an age-old question, but what is the better practice? Using a domain model object throughout all layers of your application, and even binding values directly to them on the JSP (I'm using JSF). Or convert a domain model object into a DTO in the DAO or Service layer and send a lightweight DTO to the presentation layer. I have been told it makes no sense to use DTOs because changes to the database will result in changes to all your DTOs whereas using Model Objects everywhere will just require changes to the affected model object. However, the ease of use and the lightweight nature of DTOs seems to outweigh that. I should note that my app uses Hibernate Model Objects AND uses its own custom-created model objects (meaning not bound to any DB session, always detached). Is either of the above scenarios more beneficial to a strict Model Object pattern? Using Hibernate has been a huge PITA with regards to things like Lazy Initialization Exceptions.

  • What's the output object file format of GNU assembler as?

    - by smwikipedia
    I have checked the assembler options of GNU assembler as and I didn't find an option to specify the output object file format. If I am using the following command as -o foobar.o foobar.s What object file format will I get? The as manual says that "The GNU as can be configured to produce several alternative object file formats." But how? How can I change it to a ELF format? Many thanks.

  • Why instantiation of static nested class object is allowed?

    - by Parag Meshram
    I have started learning Java language for Android Application developement. As per my understanding based on static class, we cannot instantiate object of static class. But why instantiation of static nested class object is allowed in following situaltion? class EnclosingClass { //... class static StaticInnerClass { //... } } Why we can create object of inner class if it is marked as static? EnclosingClass.StaticInnerClass s = new EnclosingClass.StaticInnerClass()

  • How to pass a serialized object to appengine java task?

    - by aloo
    Hi all, I'm using java appengine and the task queue API to run async tasks. I would like to add a task to the task queue but pass a a java object as a parameter. I notic the task options api can add a parameter as a byte[] but I'm unsure how to use it. 1) How would I serialize my object to a byte[]? and 2) How would the task read the byte[] and reconstruct the original object? Thanks.

  • cl.exe Difference in object files when /E output is the same and flags are the same

    - by madiyaan damha
    Hello: I am using Visual Studio 2005's cl.exe compiler. I call it with a bunch of /I /D and some compilation/optimization flags (example: /Ehsc). I have two compilation scripts, and both differ only in the /I flags (include directories are different). All other flags are the same. These scripts produce different object files (and not just a timestamp difference as noted below). The strange thing is that the /E output of both scripts is the same. That means that the include files are not causing the difference in object files, but then again, where is the difference coming from? Can anyone elucidate on how I am seeing two different object files in my situation. If the include files are causing the difference, how come I see identical /E output? PS. The object files are different not only in the timestamp, but in the code sections also. In fact the behavior of my final executable is different in both cases. Edit: PSS: I even looked at the /includeFiles output of cl.exe and that output is identical. The object files, however, differ in more than just the timestamp (in fact, one is 1KB bigger than another!)

  • Custom XML Serialization, how to write custom root element?

    - by Beta033
    I'm probably just doing this wrong, i know. i'm using custom serialization and when the xml is generated it's putting the class name as the root element Example: <MyClassName> <MyIntendedRootNode> <ObjectType> <Property1/> <Property2/> ... I'm inoking the serialization by calling xmlserializer.Serialize(writer,Me) so i'm sure that has something to do with it. I've tried putting XMLRoot onto the class, but i think as vb is compiling this partial class with it's aspx page, it's either overwriting this property or ignoring it entirely. ideally i'd like to just tell it to either throw away everything it has and use a different root element. Anybody else do this except me? Thanks

  • jQuery: Checking for length of ul and removing an li element?

    - by Legend
    I am trying to remove the last <li> element from a <ul> element only if it exceeds a particular length. For this, I am doing something like this: var selector = "#ulelement" if($(selector).children().length > threshold) { $(selector + " >:last").remove(); } I don't like the fact that I have to use the selector twice. Is there a shorter way to do this? Something like a "remove-if-length-greater-than-threshold" idea. I was thinking that maybe there is a way to do this using the live() function but I have no idea how.

  • Opengl Iphone SDK: How to tell if you're touching an object on screen?

    - by TheGambler
    First is my touchesBegan function and then the struct that stores the values for my object. I have an array of these objects and I'm trying to figure out when I touch the screen if I'm touching an object on the screen. I don't know if I need to do this by iterating through all my objects and figure out if I'm touching an object that way or maybe there is an easier more efficient way. How is this usually handled? -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ [super touchesEnded:touches withEvent:event]; UITouch* touch = ([touches count] == 1 ? [touches anyObject] : nil); CGRect bounds = [self bounds]; CGPoint location = [touch locationInView:self]; location.y = bounds.size.height - location.y; float xTouched = location.x/20 - 8 + ((int)location.x % 20)/20; float yTouched = location.y/20 - 12 + ((int)location.y % 20)/20; } typedef struct object_tag // Create A Structure Called Object { int tex; // Integer Used To Select Our Texture float x; // X Position float y; // Y Position float z; // Z Position float yi; // Y Increase Speed (Fall Speed) float spinz; // Z Axis Spin float spinzi; // Z Axis Spin Speed float flap; // Flapping Triangles :) float fi; // Flap Direction (Increase Value) } object;

  • How to see if an object is an array?

    - by edbras
    How can I see in Java if an Object is an array without using reflection? And how can I iterate through all items without using reflection? I use Google GWT so I am not allowed to use reflection :( I would love to implement the following methods without using refelection: private boolean isArray(final Object obj) { ??.. } private String toString(final Object arrayObject) { ??.. } BTW: neither do I want to use Javascript such that I can use it in non-GWT environments Ed

  • Is it possible to access Request object from Global.asa file?

    - by Rob Segal
    I need to get access to some server variables like APPL_PHYSICAL_PATH from the the Global.asa file. I can do this on any page of my site using the Request object as follows... Request.ServerVariables("APPL_PHYSICAL_PATH") But I don't seem to have access to the Request object within the Global.asa file. Is there an equivalent call I can do here with the Server object?

  • How to display static (shared) object's properties in a PropertyGrid?

    I would like to display static (shared) objects at runtime in a PropertyGrid but if I try to set the selected object property of the grid like this: _propertyGrid.SelectedObject = System.Windows.Forms.Application I get a compilation error: 'Application' is a type and cannot be used as an expression. Is there a way to display a static (shared) object or the object's properties in the PropertyGrid?

  • Why does this window object not have the eval function?

    - by Motti
    I ran into an interesting (?) problem in the YUI rich edit demo on IE. When looking at the window object for the content editable frame used as the browser I see that the eval function is undefined (by running the following). javascript:alert(document.getElementById("editor_editor").contentWindow.eval) This only happens on IE (I checked on IE6 and IE8), and it doesn't happen on Firefox or Chrome. All the other window functions and properties seem to be in order, now I realise that eval is not really defined on the window but on the global object but my understanding was that in browsers the window is the global object (also eval does appear on all other windows so why not on this one?). Does anyone know if this is a know bug/limitation in IE and how I can get to eval in the context of the global object of this frame? (I need the side effects to be available to anything running from within this frame).

  • How to avoid injecting dependencies into an object so that it can pass them on?

    - by Pheter
    I am interested in applying dependency injection to my current project, which makes use of the MVC pattern. My controllers will call the models and therefore will need to inject the dependencies into the models. To do this, the controller must have the dependencies (such as a database object) in the first place. The controller doesn't need to make use of some of these dependencies (such as the database object), so I feel that it shouldn't be given this dependency. However, it has to have these dependencies if it is to inject them into the model objects. How can I avoid having dependencies injected into an object just so that it can pass them on? Doing so feels wrong and can result in many dependencies being injected into an object. Edit: I am using PHP.

  • What is the equivalent of <composite-element> in Castle ActiveRecord?

    - by Daniel T.
    I have a TrackLog that has a collection of TrackPoints: public class TrackLog { public string Name { get; set; } public ISet<TrackPoint> TrackPoints { get; set; } } public class TrackPoint { public DateTime Timestamp { get; set; } public double Latitude { get; set; } public double Longitude { get; set; } } I'd like to map the track points as a collection of components, as this makes the most sense. According to the book NHibernate in Action, on page 187: Collections of components are mapped similarily to other collections of value type instances. The only difference is the use of <composite-element> in place of the familiar <element> tag. How would I do this using Castle ActiveRecord attributes?

  • How can I set the class for a <dt> element in a Zend_Form?

    I'm trying to set the width of the style for a group of < dt elements in a Zend_Form. Is there a way to set a class for a dt element, so the end result would be something like this: <dt id="name-label" class="xyz" > // trying to add the 'class="xyz" <label class="required" for="name">Name:</label> </dt> <dd id="name-element"> <input type="text" maxlength="255" size="30" value="" id="name" name="name"> </dd>

  • C# Memoization of functions with arbitrary number of arguments

    - by Lirik
    I'm trying to create a memoization interface for functions with arbitrary number of arguments, but I'm failing miserably. The first thing I tried is to define an interface for a function which gets memoized automatically upon execution: class EMAFunction:IFunction { Dictionary<List<object>, List<object>> map; class EMAComparer : IEqualityComparer<List<object>> { private int _multiplier = 97; public bool Equals(List<object> a, List<object> b) { List<object> aVals = (List<object>)a[0]; int aPeriod = (int)a[1]; List<object> bVals = (List<object>)b[0]; int bPeriod = (int)b[1]; return (aVals.Count == bVals.Count) && (aPeriod == bPeriod); } public int GetHashCode(List<object> obj) { // Don't compute hash code on null object. if (obj == null) { return 0; } // Get length. int length = obj.Count; List<object> vals = (List<object>) obj[0]; int period = (int) obj[1]; return (_multiplier * vals.GetHashCode() * period.GetHashCode()) + length;; } } public EMAFunction() { NumParams = 2; Name = "EMA"; map = new Dictionary<List<object>, List<object>>(new EMAComparer()); } #region IFunction Members public int NumParams { get; set; } public string Name { get; set; } public object Execute(List<object> parameters) { if (parameters.Count != NumParams) throw new ArgumentException("The num params doesn't match!"); if (!map.ContainsKey(parameters)) { //map.Add(parameters, List<double> values = new List<double>(); List<object> asObj = (List<object>)parameters[0]; foreach (object val in asObj) { values.Add((double)val); } int period = (int)parameters[1]; asObj.Clear(); List<double> ema = TechFunctions.ExponentialMovingAverage(values, period); foreach (double val in ema) { asObj.Add(val); } map.Add(parameters, asObj); } return map[parameters]; } public void ClearMap() { map.Clear(); } #endregion } Here are my tests of the function: private void MemoizeTest() { DataSet dataSet = DataLoader.LoadData(DataLoader.DataSource.FROM_WEB, 1024); List<String> labels = dataSet.DataLabels; Stopwatch sw = new Stopwatch(); IFunction emaFunc = new EMAFunction(); List<object> parameters = new List<object>(); int numRuns = 1000; long sumTicks = 0; parameters.Add(dataSet.GetValues("open")); parameters.Add(12); // First call for(int i = 0; i < numRuns; ++i) { emaFunc.ClearMap();// remove any memoization mappings sw.Start(); emaFunc.Execute(parameters); sw.Stop(); sumTicks += sw.ElapsedTicks; } Console.WriteLine("Average ticks not-memoized " + (sumTicks/numRuns)); sumTicks = 0; // Repeat call for (int i = 0; i < numRuns; ++i) { sw.Start(); emaFunc.Execute(parameters); sw.Stop(); sumTicks += sw.ElapsedTicks; } Console.WriteLine("Average ticks memoized " + (sumTicks/numRuns)); } The performance is confusing me... I expected the memoized function to be faster, but it didn't work out that way: Average ticks not-memoized 106,182 Average ticks memoized 198,854 I tried doubling the data instances to 2048, but the results were about the same: Average ticks not-memoized 232,579 Average ticks memoized 446,280 I did notice that it was correctly finding the parameters in the map and it going directly to the map, but the performance was still slow... I'm either open for troubleshooting help with this example, or if you have a better solution to the problem then please let me know what it is.
