  • Bind DataGrid to Dictionary in ASP.NET

    - by mcoolbeth
    In ASP.NET, binding a DataGrid to a list of objects is super-easy. I end up with a row for each object in the list, and any cell in a given row is bound to a property of the corresponding object. However, suppose one of the properties of my object is a dictionary, and each is expected to contain a specific key. Is there any way to bind one of my DataGridColumns to that dictionary key? Thanks.

  • How to invalidate cache when benchmarking?

    - by Michael Buen
    I have this code, that when swapping the order of UsingAs and UsingCast, their performance also swaps. using System; using System.Diagnostics; using System.Linq; using System.IO; class Test { const int Size = 30000000; static void Main() { object[] values = new MemoryStream[Size]; UsingAs(values); UsingCast(values); Console.ReadLine(); } static void UsingCast(object[] values) { Stopwatch sw = Stopwatch.StartNew(); int sum = 0; foreach (object o in values) { if (o is MemoryStream) { var m = (MemoryStream)o; sum += (int)m.Length; } } sw.Stop(); Console.WriteLine("Cast: {0} : {1}", sum, (long)sw.ElapsedMilliseconds); } static void UsingAs(object[] values) { Stopwatch sw = Stopwatch.StartNew(); int sum = 0; foreach (object o in values) { if (o is MemoryStream) { var m = o as MemoryStream; sum += (int)m.Length; } } sw.Stop(); Console.WriteLine("As: {0} : {1}", sum, (long)sw.ElapsedMilliseconds); } } Outputs: As: 0 : 322 Cast: 0 : 281 When doing this... UsingCast(values); UsingAs(values); ...Results to this: Cast: 0 : 322 As: 0 : 281 When doing just this... UsingAs(values); ...Results to this: As: 0 : 322 When doing just this: UsingCast(values); ...Results to this: Cast: 0 : 322 Aside from running them independently, how to invalidate the cache so the second code being benchmarked won't receive the cached memory of first code? Benchmarking aside, just loved the fact that modern processors do this caching magic :-)

  • Broadcasting an intent to a specific component.

    - by Nic Strong
    I have an activity that is starting a background operation in another service. This activity receives various notifications from this service. As part of the intent I use to initiate the background operation I pass extra data with the context of my activity so the background service can broadcast intents back to me (the download service is a good example of this usage). So in the activity I use the following to attach the context: intent.putExtra(Intents.EXTRA_NOTIFICATION_PACKAGE, IntentTestActivity.this.getPackageName()); intent.putExtra(Intents.EXTRA_NOTIFICATION_CLASS, IntentTestActivity.class.getCanonicalName()); intent.putExtra(Intents.EXTRA_NOTIFICATION_EXTRAS, myContext); I register for the notifications in the activity: IntentFilter intentFilter = new IntentFilter(); intentFilter.addAction(Intents.ACTION_NOTIFICATION); intentFilter.addCategory(Intents.CATEGORY_COMPLETION); intentFilter.addCategory(Intents.CATEGORY_PROGRESSS); Intent intent = registerReceiver(receiver, intentFilter); In the background service I send notifications with the following code: void broadcastNotification(String action, String category, String packageName, String className, String extras, int operationResult) { Intent intent = new Intent(action); intent.addCategory(category); intent.setClassName(packageName, className); if (extras != null) { intent.putExtra(Intents.EXTRA_NOTIFICATION_EXTRAS, extras); } intent.putExtra(Intents.EXTRA_OPERATION_RESULT, operationResult); context.sendBroadcast(intent); } My problem is that the above broadcast will never be received. If however I comment out the line intent.setClassName(packageName, className); Then the broadcast is received. Is it a problem with my filter? Do I have to specify intents intended for a specific component? Or cannot I not use such fine grain control over the delivery of broadcasts. Thanks, Nic

  • Partial template specialization on a class

    - by Jonathan Swinney
    I'm looking for a better way to this. I have a chunk of code that needs to handle several different objects that contain different types. The structure that I have looks like this: class Base { // some generic methods } template <typename T> class TypedBase : public Base { // common code with template specialization private: std::map<int,T> mapContainingSomeDataOfTypeT; } template <> class TypedBase<std::string> : public Base { // common code with template specialization public: void set( std::string ); // functions not needed for other types std::string get(); private: std::map<int,std::string> mapContainingSomeDataOfTypeT; // some data not needed for other types } Now I need to add some additional functionality that only applies to one of the derivative classes. Specifically the std::string derivation, but the type doesn't actually matter. The class is big enough that I would prefer not copy the whole thing simply to specialize a small part of it. I need to add a couple of functions (and accessor and modifier) and modify the body of several of the other functions. Is there a better way to accomplish this?

  • How could a quine in my programming language look?

    - by ads
    I have created a turing-complete programming language (already proven) so it must be possible to write a quine for it, right? But all quines I know store their source code in a string and then replace a special character in it using something like chr and ord. My language only has the following Basic arithmetics Int and string types Variables == operator Conditional gotos I have no idea how I could write a quine as I have no real string manipulation available, I can only output constant strings. Yet, it is 100% turing-complete.

  • XmlSerializer throws exception when serializing dynamically loaded type

    - by Dr. Sbaitso
    Hi I'm trying to use the System.Xml.Serialization.XmlSerializer to serialize a dynamically loaded (and compiled class). If I build the class in question into the main assembly, everything works as expected. But if I compile and load the class from an dynamically loaded assembly, the XmlSerializer throws an exception. What am I doing wrong? I've created the following .NET 3.5 C# application to reproduce the issue: using System; using System.Collections.Generic; using System.Xml.Serialization; using System.Text; using System.Reflection; using System.CodeDom.Compiler; using Microsoft.CSharp; public class StaticallyBuiltClass { public class Item { public string Name { get; set; } public int Value { get; set; } } private List<Item> values = new List<Item>(); public List<Item> Values { get { return values; } set { values = value; } } } static class Program { static void Main() { RunStaticTest(); RunDynamicTest(); } static void RunStaticTest() { Console.WriteLine("-------------------------------------"); Console.WriteLine(" Serializing StaticallyBuiltClass..."); Console.WriteLine("-------------------------------------"); var stat = new StaticallyBuiltClass(); Serialize(stat.GetType(), stat); Console.WriteLine(); } static void RunDynamicTest() { Console.WriteLine("-------------------------------------"); Console.WriteLine(" Serializing DynamicallyBuiltClass..."); Console.WriteLine("-------------------------------------"); CSharpCodeProvider csProvider = new CSharpCodeProvider(new Dictionary<string, string> { { "CompilerVersion", "v3.5" } }); CompilerParameters csParams = new System.CodeDom.Compiler.CompilerParameters(); csParams.GenerateInMemory = true; csParams.GenerateExecutable = false; csParams.ReferencedAssemblies.Add("System.dll"); csParams.CompilerOptions = "/target:library"; StringBuilder classDef = new StringBuilder(); classDef.AppendLine("using System;"); classDef.AppendLine("using System.Collections.Generic;"); classDef.AppendLine(""); classDef.AppendLine("public class DynamicallyBuiltClass"); classDef.AppendLine("{"); classDef.AppendLine(" public class Item"); classDef.AppendLine(" {"); classDef.AppendLine(" public string Name { get; set; }"); classDef.AppendLine(" public int Value { get; set; }"); classDef.AppendLine(" }"); classDef.AppendLine(" private List<Item> values = new List<Item>();"); classDef.AppendLine(" public List<Item> Values { get { return values; } set { values = value; } }"); classDef.AppendLine("}"); CompilerResults res = csProvider.CompileAssemblyFromSource(csParams, new string[] { classDef.ToString() }); foreach (var line in res.Output) { Console.WriteLine(line); } Assembly asm = res.CompiledAssembly; if (asm != null) { Type t = asm.GetType("DynamicallyBuiltClass"); object o = t.InvokeMember("", BindingFlags.CreateInstance, null, null, null); Serialize(t, o); } Console.WriteLine(); } static void Serialize(Type type, object o) { var serializer = new XmlSerializer(type); try { serializer.Serialize(Console.Out, o); } catch(Exception ex) { Console.WriteLine("Exception caught while serializing " + type.ToString()); Exception e = ex; while (e != null) { Console.WriteLine(e.Message); e = e.InnerException; Console.Write("Inner: "); } Console.WriteLine("null"); Console.WriteLine(); Console.WriteLine("Stack trace:"); Console.WriteLine(ex.StackTrace); } } } which generates the following output: ------------------------------------- Serializing StaticallyBuiltClass... ------------------------------------- <?xml version="1.0" encoding="IBM437"?> <StaticallyBuiltClass xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Values /> </StaticallyBuiltClass> ------------------------------------- Serializing DynamicallyBuiltClass... ------------------------------------- Exception caught while serializing DynamicallyBuiltClass There was an error generating the XML document.

  • TinyMCE is modifying the XHTML 1.0 Strict HTML I input. How can I stop it?

    - by Matt
    The code I want to have saved through TinyMCE is as follows: <object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="550" height="90" id="homepage-banner"> <param name="movie" value="/images/header.swf" /> <param name="wmode" value="transparent" /> <!--[if !IE]>--> <object type="application/x-shockwave-flash" data="/images/header.swf" width="550" height="90"> <param name="wmode" value="transparent" /> <!--<![endif]--> <img src="/images/header.jpg" width="550" height="90" alt="" border="0" /> <!--[if !IE]>--> </object> <!--<![endif]--> </object> Sadly, what I end up with is: <object data="/images/header.swf" height="90" type="application/x-shockwave-flash" width="550"> <param name="id" value="homepage-banner" /> <param name="wmode" value="transparent" /> <param name="src" value="/images/header.swf" /> </object> The purpose of the stripped parts of the code is to provide a fallback image if flash is not available on the client. In my tinyMCE.init({ ... }); I am using verify_html: true and valid_elements is set as per this forum topic whereby all valid XHTML 1.0 Strict elements are allowed. I have checked and the above code does comply with the XHTML 1.0 Strict standard. I have tried just setting verify_html to false but it had no effect. How can TinyMCE be configured to leave my HTML alone?!

  • Regex Pattern for ignoring a custom escape character

    - by user1517464
    I am trying to find a suitable regex for matching pair of custom characters in an input string. These custom characters are replaced by their corresponding html tags. For e.g. The input string can have underscores in pairs to indicate words in bold. Hence, _Name_ outputs as <b>Name</b> However if there is a genuine underscore in the string, it cannot be replaced by "bold" tags and has to be ignored. The genuine underscore has to be preceded by / (I couldn't find a better character, it could be one more underscore or hyphen or whatever). Any single or paired occurrance of this genuine underscore has to be ignored by regex. So far I could come up with this regex: var pattern = @"(?!/)_(.*?)(?!/)_"; But it fails in below input string: _Tom_Katy/_Richard/_/_Stephan_and many users It outputs as <b>Tom</b>Katy/<b>Richard/_/</b>Stephan_and many users Many Thanks in Advance, Pr

  • Convert in memory POCO objects to c# code to initialize

    - by sidesinger
    Is there a library or code sample for converting an in memory POCO c# object to a .cs code file that creates that object. An example: object of type car in memory becomes: Car c = new Car { Name = "mazda", Id = 5, Passengers = new List<string> { "Bob", "Sally" } // etc... recursing to the bottom }; I could assume it could only set public properties.

  • Button control subclass: click event does not fire when using UpdatePanel

    - by nw
    Using suggestions from this thread, I created a ModernButton control that uses the HTML button tag instead of input. This control works great except when embedded within an UpdatePanel control. In this case, it does trigger the partial postback, but its click event does not fire. The control is defined thus: [ParseChildren(false)] [PersistChildren(true)] public class ModernButton : Button { private string _iconURL = ""; protected override string TagName { get { return "button"; } } protected override HtmlTextWriterTag TagKey { get { return HtmlTextWriterTag.Button; } } public new string Text { get { return ViewState["NewText"] as string; } set { ViewState["NewText"] = HttpUtility.HtmlDecode(value); } } public string IconURL { get { return this._iconURL; } set { this._iconURL = value.Trim(); } } protected override void OnPreRender(System.EventArgs e) { base.OnPreRender(e); LiteralControl textCtrl = new LiteralControl(this.Text); if (this._iconURL != "") { LiteralControl openDiv = new LiteralControl( string.Format( "<div style=\"background-image:url({0}); background-position:left center; background-repeat:no-repeat; line-height:16px; padding:3px 0 3px 22px;\">", ResolveClientUrl(this._iconURL) ) ); LiteralControl closeDiv = new LiteralControl("</div>"); Controls.AddAt(0, openDiv); Controls.Add(textCtrl); Controls.Add(closeDiv); } else { Controls.Add(textCtrl); } base.Text = UniqueID; } protected override void RenderContents(HtmlTextWriter writer) { RenderChildren(writer); } } I use it so: <asp:UpdatePanel runat="server" ID="uxSearchPanel" ChildrenAsTriggers="true" UpdateMode="Conditional"> <Triggers> <asp:AsyncPostBackTrigger ControlID="uxSearchButton" /> </Triggers> <ContentTemplate> ... <ctrl:ModernButton ID="uxSearchButton" runat="server" Text="Search" IconURL="Icons/magnifier.png" OnClick="uxSearchButton_Click"></ctrl:ModernButton> </ContentTemplate> </asp:UpdatePanel> Which renders: <div id="uxBody_uxSearchPanel"> ... <button type="submit" name="ctl00$uxBody$uxSearchButton" value="ctl00$uxBody$uxSearchButton" id="uxBody_uxSearchButton"> <div style="background-image:url(Icons/magnifier.png); background-position:left center; background-repeat:no-repeat; line-height:16px; padding:3px 0 3px 22px;">Search</div> </button> </div> The ModernButton generates a postback in every case (whether partial or full), but the server-side click event (uxSearchButton_Click) does not fire in the partial postback scenario.

I have 2 objects. Each object have DateTime fields ValidFrom, ValidTo. First i save an object with ValidTo using the application setting MaxDate (SQL-server maxdate 9999-12-12). Then when I save a new object and that object ValidFrom is within the first objects ValidFrom - ValidTo timespan I want to change first objects ValidTo datetime to previous day of new objects ValidTo datetime.

  • Implementing INotifyPropertyChanged with PostSharp 1.5

    - by no9
    Hello all. Im new to .NET and WPF so i hope i will ask the question correctly. I am using INotifyPropertyChanged implemented using PostSharp 1.5: [Serializable, DebuggerNonUserCode, AttributeUsage(AttributeTargets.Assembly | AttributeTargets.Class, AllowMultiple = false, Inherited = false), MulticastAttributeUsage(MulticastTargets.Class, AllowMultiple = false, Inheritance = MulticastInheritance.None, AllowExternalAssemblies = true)] public sealed class NotifyPropertyChangedAttribute : CompoundAspect { public int AspectPriority { get; set; } public override void ProvideAspects(object element, LaosReflectionAspectCollection collection) { Type targetType = (Type)element; collection.AddAspect(targetType, new PropertyChangedAspect { AspectPriority = AspectPriority }); foreach (var info in targetType.GetProperties(BindingFlags.Public | BindingFlags.Instance).Where(pi => pi.GetSetMethod() != null)) { collection.AddAspect(info.GetSetMethod(), new NotifyPropertyChangedAspect(info.Name) { AspectPriority = AspectPriority }); } } } [Serializable] internal sealed class PropertyChangedAspect : CompositionAspect { public override object CreateImplementationObject(InstanceBoundLaosEventArgs eventArgs) { return new PropertyChangedImpl(eventArgs.Instance); } public override Type GetPublicInterface(Type containerType) { return typeof(INotifyPropertyChanged); } public override CompositionAspectOptions GetOptions() { return CompositionAspectOptions.GenerateImplementationAccessor; } } [Serializable] internal sealed class NotifyPropertyChangedAspect : OnMethodBoundaryAspect { private readonly string _propertyName; public NotifyPropertyChangedAspect(string propertyName) { if (string.IsNullOrEmpty(propertyName)) throw new ArgumentNullException("propertyName"); _propertyName = propertyName; } public override void OnEntry(MethodExecutionEventArgs eventArgs) { var targetType = eventArgs.Instance.GetType(); var setSetMethod = targetType.GetProperty(_propertyName); if (setSetMethod == null) throw new AccessViolationException(); var oldValue = setSetMethod.GetValue(eventArgs.Instance, null); var newValue = eventArgs.GetReadOnlyArgumentArray()[0]; if (oldValue == newValue) eventArgs.FlowBehavior = FlowBehavior.Return; } public override void OnSuccess(MethodExecutionEventArgs eventArgs) { var instance = eventArgs.Instance as IComposed<INotifyPropertyChanged>; var imp = instance.GetImplementation(eventArgs.InstanceCredentials) as PropertyChangedImpl; imp.OnPropertyChanged(_propertyName); } } [Serializable] internal sealed class PropertyChangedImpl : INotifyPropertyChanged { private readonly object _instance; public PropertyChangedImpl(object instance) { if (instance == null) throw new ArgumentNullException("instance"); _instance = instance; } public event PropertyChangedEventHandler PropertyChanged; internal void OnPropertyChanged(string propertyName) { if (string.IsNullOrEmpty(propertyName)) throw new ArgumentNullException("propertyName"); var handler = PropertyChanged as PropertyChangedEventHandler; if (handler != null) handler(_instance, new PropertyChangedEventArgs(propertyName)); } } } Then i have a couple of classes (user and adress) that implement [NotifyPropertyChanged]. It works fine. But what i want would be that if the child object changes (in my example address) that the parent object gets notified (in my case user). Would it be possible to expand this code so it automaticly creates listeners on parent objects that listen for changes in its child objets?

  • Java - abstract class, equals(), and two subclasses

    - by msr
    Hello, I have an abstract class named Xpto and two subclasses that extend it named Person and Car. I have also a class named Test with main() and a method foo() that verifies if two persons or cars (or any object of a class that extends Xpto) are equals. Thus, I redefined equals() in both Person and Car classes. Two persons are equal when they have the same name and two cars are equal when they have the same registration. However, when I call foo() in the Test class I always get "false". I understand why: the equals() is not redefined in Xpto abstract class. So... how can I compare two persons or cars (or any object of a class that extends Xpto) in that foo() method? In summary, this is the code I have: public abstract class Xpto { } public class Person extends Xpto{ protected String name; public Person(String name){ this.name = name; } public boolean equals(Person p){ System.out.println("Person equals()?"); return this.name.compareTo(p.name) == 0 ? true : false; } } public class Car extends Xpto{ protected String registration; public Car(String registration){ this.registration = registration; } public boolean equals(Car car){ System.out.println("Car equals()?"); return this.registration.compareTo(car.registration) == 0 ? true : false; } } public class Teste { public static void foo(Xpto xpto1, Xpto xpto2){ if(xpto1.equals(xpto2)) System.out.println("xpto1.equals(xpto2) -> true"); else System.out.println("xpto1.equals(xpto2) -> false"); } public static void main(String argv[]){ Car c1 = new Car("ABC"); Car c2 = new Car("DEF"); Person p1 = new Person("Manel"); Person p2 = new Person("Manel"); foo(p1,p2); } }

  • How to handle Oracle Stored Proc with ASP.NET and Oracle Data Provider?

    - by Matt
    I have been struggling with this for quite some time having been accustomed to SQL Server. I have the following code and I have verified that the OracleDbType's are correct and have verified that the actual values being passed to the parameters match. I think my problem may rest with the return value. All it does is give me the row count. I read somewhere that the return parameter must be set at the top. The specific error I am getting says, PLS-00306: wrong number or types of arguments in call to \u0027INSERT_REC\u0027 ORA-06550: line 1, column 7:\nPL/SQL: Statement ignored The stored procedure is: PROCEDURE INSERT_REC ( A_MILL_CENTER IN GRO_OWNER.MOVEMENT.MILL_CENTER%TYPE, --# VARCHAR2(10) A_INGREDIENT_CODE IN GRO_OWNER.MOVEMENT.INGREDIENT_CODE%TYPE, --# VARCHAR2(50) A_FEED_CODE IN GRO_OWNER.MOVEMENT.FEED_CODE%TYPE, --# VARCHAR2(30) --# A_MOVEMENT_TYPE should be ‘RECEIPT’ for ingredient receipts A_MOVEMENT_TYPE IN GRO_OWNER.MOVEMENT.MOVEMENT_TYPE%TYPE, --# VARCHAR2(10) A_MOVEMENT_DATE IN VARCHAR2, --# VARCHAR2(10) A_MOVEMENT_QTY IN GRO_OWNER.MOVEMENT.MOVEMENT_QTY%TYPE, --# NUMBER(12,4) --# A_INVENTORY_TYPE should be ‘INGREDIENT’ or ‘FINISHED’ A_INVENTORY_TYPE IN GRO_OWNER.MOVEMENT.INVENTORY_TYPE%TYPE, --# VARCHAR2(10) A_CREATE_USERID IN GRO_OWNER.MOVEMENT.CREATE_USERID%TYPE, --# VARCHAR2(20) A_RETURN_VALUE OUT NUMBER --# NUMBER(10,0) ); My code is as follows: //3 items hardcoded for now string millCenter = "0010260510"; string movementType = "RECEIPT"; string feedCode = "test this"; string userID = "GRIMMETTM"; string inventoryType = "INGREDIENT"; //set to FINISHED for feed stuff string movementDate = theData[i]; string ingCode = System.Text.RegularExpressions.Regex.Match(theData[i + 1], @"^([0-9]*)").ToString(); //int pounds = Convert.ToInt32(theData[i + 2].Replace(",", "")); int pounds = 100; //setup parameters OracleParameter p9 = new OracleParameter("A_RETURN_VALUE", OracleDbType.Int32, 30); p9.Direction = ParameterDirection.ReturnValue; oraCmd.Parameters.Add(p9); OracleParameter p1 = new OracleParameter("A_MILL_CENTER", OracleDbType.Varchar2, 10); p1.Direction = ParameterDirection.Input; p1.Value = millCenter; oraCmd.Parameters.Add(p1); OracleParameter p2 = new OracleParameter("A_INGREDIENT_CODE", OracleDbType.Varchar2, 50); p2.Direction = ParameterDirection.Input; p2.Value = ingCode; oraCmd.Parameters.Add(p2); OracleParameter p3 = new OracleParameter("A_FEED_CODE", OracleDbType.Varchar2, 30); p3.Direction = ParameterDirection.Input; p3.Value = feedCode; oraCmd.Parameters.Add(p3); OracleParameter p4 = new OracleParameter("A_MOVEMENT_TYPE", OracleDbType.Varchar2, 10); p4.Direction = ParameterDirection.Input; p4.Value = movementType; oraCmd.Parameters.Add(p4); OracleParameter p5 = new OracleParameter("A_MOVEMENT_DATE", OracleDbType.Varchar2, 10); p5.Direction = ParameterDirection.Input; p5.Value = movementDate; oraCmd.Parameters.Add(p5); OracleParameter p6 = new OracleParameter("A_MOVEMENT_QTY", OracleDbType.Int32, 12); p6.Direction = ParameterDirection.Input; p6.Value = pounds; oraCmd.Parameters.Add(p6); OracleParameter p7 = new OracleParameter("A_INVENTORY_TYPE", OracleDbType.Varchar2, 10); p7.Direction = ParameterDirection.Input; p7.Value = inventoryType; oraCmd.Parameters.Add(p7); OracleParameter p8 = new OracleParameter("A_CREATE_USERID", OracleDbType.Varchar2, 20); p8.Direction = ParameterDirection.Input; p8.Value = userID; oraCmd.Parameters.Add(p8); //open and execute oraConn.Open(); oraCmd.ExecuteNonQuery(); oraConn.Close();

  • C# File.ReadAllLines not breaking on line feeds

    - by David Dickerson
    Hello, I have an application that I am building that needs to modify a configuration file. My problem is that I am not able to read the file in line by line. I keep geeting the the entire file as a single string. string ConfigTemplate = AEBuildsSPFolderName + "\Template_BuildReleaseScript.Config"; string[] fileSourceLines = File.ReadAllLines(ConfigTemplate, Encoding.Default); --Returns the entire file contents into the first array element. using (StreamReader reader = new StreamReader(ConfigTemplate)) { string line; while ((line = reader.ReadLine()) != null) --Returns the entire file contents into the first line read. Any idea of what I am doing wrong? Thanks, david
