$(".delete").click( function() { var thesender = this; $(thesender).text("Del..."); $.getJSON("ajax.php", {}, function(data) { if (data["result"]) $(thesender).remove(); // variable defined outside else alert('Error!'); ...
I hope I worded the title of my question appropriately. In c# I can use lambdas (as delegates), or the older delegate syntax to do this: Func<string> fnHello = () => "hello"; Console.WriteLine(fnHello()); Func<string> fnHello2 = delegate() { return "hello 2"; }; Console.WriteLine(fnHello2()); So why can't I "inline" the lambda o...
private static Dictionary<Type, Func<string, object>> _parseActions = new Dictionary<Type, Func<string, object>> { { typeof(bool), value => {Convert.ToBoolean(value) ;}} }; The above gives an error Error 14 Not all code paths return a value in lambda expression of type 'System...
In my gridview I have fields for inserting a new record in the footer. In my objectdatasource selecting event if no records came back I bind a single mock row to force the footer to show so they can still add records. Since the row does not contain real data I hide the row. ... If result.ItemCount = 0 Then result = mock...
I want to modify a local variable in a function of extension method. See int myvar=0; MyList.Where( x => { if (condition) myvar += 1; return false; }); return myvar; Why that is not working? ...
I am trying to make a function return data from an ajax call that I can then use. The issue is the function itself is called by many objects, e.g.: function ajax_submit (obj) { var id = $(obj).attr('id'); var message = escape ($("#"+id+" .s_post").val ()); var submit_string = "action=post_message&message="+message; ...
Hi, I do not understand how following code works. Specifically, I do not understand using of "return i<3". I would expect return i IF its < than 3. I always though that return just returns value. I could not even find what syntax is it. Second question, it seems to me like using anonymous method (delegate(int i)) but could be possible t...
What I want to do is to assign an anonymous method which I get as a function result to a variable of the same type. Delphi complains about not beeing able to do the assignement. Obviously Delphi things I want to assign the "GetListener" function instead of the result of that same function. Any help with this is very much appreciated. ...
I would like to have the following to be translated to VB 2010 (with advanced syntaxes) _domainContext.SubmitChanges( submitOperation => { _domainContext.Load<Customer>( _domainContext.GetCustomersQuery(), LoadBehavior.RefreshCurrent, loadOperation => { ...
I have a doubt in scope of varibles inside anonymous functions in C#. Consider the program below: delegate void OtherDel(int x); public static void Main() { OtherDel del2; { int y = 4; del2 = delegate { Console.WriteLine("{0}...
Ok, So I have a method which fires when someone clicks on our Icon in a silverlight application, seen below: private void Logo_MouseLeftButtonUp(object sender, MouseButtonEventArgs e) { e.Handled = true; ShowInfo(true); DispatcherTimer autoCloseTimer = new DispatcherTimer(); autoCloseTimer.Inter...
Let me try to give a little example. class Session ( public delegate string CleanBody(); public static void Execute(string name, string q, CleanBody body) ... can be used like: Session.Execute("foo", "bar", delegate() { string x="beep"; /* whatever*/ return x; }); But what if I need to run is via MethodInfo.Invoke -- as in ...
I am trying to get my code working as per the instruction on http://www.paulstovell.com/vb-anonymous-methods So far I have the wrapper: Public Delegate Function PredicateWrapperDelegate(Of T, A)(ByVal item As T, ByVal argument As A) As Boolean Public Class PredicateWrapper(Of T, A) Private _argument As A Private _wrapperDelegat...
I'm currently having to integrate a lot of web service calls inside Silverlight that make calls similar to the code below. No user interaction should be possible until the loading of all 3 is complete. // In my view, having standard delegate methods (non-anonymous) makes the // code below even messier. // I've left out the EventArgs t...
Obviously, I'm not an expert in C#. I would like to simplify this code by using an anonymous handler, or maybe a lambda, not sure. ValueHasChanged is a PropertyChangedCallback used when a dp is changed, it ensures the new object will be monitored for update, so that both changes and updates will be processed using the same code: ProcessN...
Hi, Why can't I have this? I mean it would spare a delegate declaration: int X=delegate int(){...}; I know it can be done this way: delegate int IntDelegate(); ... IntDelegate del=delegate(){return 25;}; int X=del(); ...
Greetings, I'm working in a code base that uses alot of anonymous methods, where the anonymous methods are chaining other anonymus methods that call the same thing the first one calls. main() { anonymous1(); } anonymous1() { // call anonymous2 } anonymous2() { //call anonymous3 } anonymous3() { // Call anonymous1 } thats th...
I'd like to start using generics and anonymous method, mainly to learn what that's all about and why I would want to use them. Having Delphi 2009, I often read that generics and anonymous methods are not completely implemented or buggy, which was fixed in Delphi 2010. I would like to avoid having to wonder if it's my fault or a bug in ...
Okay, in python one can do this: def foo(monkeys): def bar(monkey): #process and return new monkey processed_monkeys = list() for monkey in monkeys: processed_monkeys += bar(monkey) return processed_monkeys (This is just a stupid example) I sometimes miss this functionality of declaring a method inside ...
While learning on anonymous methods, i've found the following example on the internet: namespace AnonymousMethods { public class MyClass { public delegate void MyDelegate(string message); //delegate accepting method with string parameter public event MyDelegate MyEvent; public void RaiseMyEvent(string ms...
