  • How to refactor logging in C#?

    - by Jader Dias
    In my services all exposed methods have: try { // the method core is written here } catch(Exception ex) { Log.Append(ex); } It's boring and ugly to repeat it over and over again. There is any way to avoid that? There is better way to keep the service working even if exceptions occurs and keep sending the exception details to the Log class?

  • Supporting twitter-like user page urls with apache/php?

    - by user246114
    Hi, I'm using php on apache with mysql. I want to let users enter a url into their browser to see a custom user page for themselves, just like twitter does. For example, they could enter urls like: www.mysite.com/johndoe www.mysite.com/janedoe and see that user's page. How could I do this with php and apache? I don't want to create a folder on disk for every user like above, I'd instead kind of like to catch the url and generate the page on the fly for them, Thanks

  • Any way to anticipate session timeout ?

    - by Tom
    Hi, Is there a way to "catch" the session timeout event, so as to retrieve data from HttpSession before its invalidated ? We're implementing the Filter Interface, and in the doFilter method, the user we stored in the session object at login is null when session times out. Thanks in advance.

  • Translating a C# WCF app into Visual Basic

    - by MikeG
    I'm trying to write a simple/small Windows Communication Foundation service application in Visual Basic (but I am very novice in VB) and all the good examples I've found on the net are written in C#. So far I've gotten my WCF service application working but now I'm trying to add callback functionality and the program has gotten more complicated. In the C# example code I understand how everything works but I am having trouble translating into VB the portion of code that uses a delegate. Can someone please show the VB equivalent? Here is the C# code sample I'm using for reference: namespace WCFCallbacks { using System; using System.ServiceModel; [ServiceContract(CallbackContract = typeof(IMessageCallback))] public interface IMessage { [OperationContract] void AddMessage(string message); [OperationContract] bool Subscribe(); [OperationContract] bool Unsubscribe(); } interface IMessageCallback { [OperationContract(IsOneWay = true)] void OnMessageAdded(string message, DateTime timestamp); } } namespace WCFCallbacks { using System; using System.Collections.Generic; using System.ServiceModel; public class MessageService : IMessage { private static readonly List<IMessageCallback> subscribers = new List<IMessageCallback>(); //The code in this AddMessage method is what I'd like to see re-written in VB... public void AddMessage(string message) { subscribers.ForEach(delegate(IMessageCallback callback) { if (((ICommunicationObject)callback).State == CommunicationState.Opened) { callback.OnMessageAdded(message, DateTime.Now); } else { subscribers.Remove(callback); } }); } public bool Subscribe() { try { IMessageCallback callback = OperationContext.Current.GetCallbackChannel<IMessageCallback>(); if (!subscribers.Contains(callback)) subscribers.Add(callback); return true; } catch { return false; } } public bool Unsubscribe() { try { IMessageCallback callback = OperationContext.Current.GetCallbackChannel<IMessageCallback>(); if (!subscribers.Contains(callback)) subscribers.Remove(callback); return true; } catch { return false; } } } } I was thinking I could do something like this but I don't know how to pass the message string from AddMessage to DoSomething... Dim subscribers As New List(Of IMessageCallback) Public Sub AddMessage(ByVal message As String) Implements IMessage.AddMessage Dim action As Action(Of IMessageCallback) action = AddressOf DoSomething subscribers.ForEach(action) 'Or this instead of the above three lines: 'subscribers.ForEach(AddressOf DoSomething) End Sub Public Sub DoSomething(ByVal callback As IMessageCallback) 'I am also confused by: '((ICommunicationObject)callback).State 'Is that casting the callback object as type ICommunicationObject? 'How is that done in VB? End Sub

  • How to determine whether or not a video format is supported

    - by Tal Even-Tov
    Hi, I've had to write an application that lists and plays tutorial videos along with accompanying text. It works well but since the videos are added by the user I need a way of checking to see whether or not a video can be played on the machine. I'm not sure whether or not there is an easy way to try test the file (and catch errors) or if I need to start looking at codecs installed. Does anybody have any experience with this?

  • What happens inside the try block?

    - by dontWatchMyProfile
    Example: @try { // 1) do bad stuff that can throw an exception... // 2) do some more stuff // 3) ...and more... } @catch (NSException *e) { NSLog(@"Error: %@: %@", [e name], [e reason]); } If 1) throws an exception, is the block immediately canceled like a return in a function or a break in a loop? Or will 2) and 3) be processed no matter what happens in 1)?

  • How to know when an upload is done?

    - by mr1031011
    I'm using Guzzle 4 (latest version) to upload file to a remote server, since it uses stream to upload the $response-getStatusCode() will be 100 which means "Continue" and the responseBody is not available at this point. Is there a way to catch the remote server response when the upload is done? Edit 1: I was able to call back to a function when the upload is done using this: https://github.com/guzzle/progress-subscriber However, I haven't found out how to get the response yet

    - by nexes
    I have a very simple server written in C and an equally simple client written in Java.
