    Hi I have a class DataObject as Header ::: #import <Foundation/Foundation.h> @interface DataObject : NSObject { NSString *erorrMessage; BOOL hasError; NSDictionary *dataValues; } @property(nonatomic, retain)NSString *erorrMessage; @property(nonatomic)BOOL hasError; @property(nonatomic, retain)NSDictionary *dataValues; @end Class Implementation:::: #import "DataObject.h" @implementation DataObject @synthesize erorrMessage; @synthesize hasError; @synthesize dataValues; @end And I have another class as DataManager Header as :::: #import <Foundation/Foundation.h> @interface DataManager : NSObject - (DataObject *)getData :(NSString*)url; @end Implementation :::: #import "DataManager.h" #import "DataObject.h" #import "JSON.h" @implementation DataManager - (DataObject *)getData :(NSString*)url{ DataObject* dataObject = [[DataObject alloc]init]; NSString *urlString = [NSString stringWithFormat:url]; NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:urlString]]; //TODO: Here we have to check the internet connection before requesting. NSError * erorrOnRequesting; NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:&erorrOnRequesting]; NSString* responseString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; if( erorrOnRequesting != nil) { dataObject.hasError = YES; dataObject.erorrMessage = @"Error on requsting to the web server"; return dataObject; } NSError *errorOnParsing; SBJSON *json = [[SBJSON new] autorelease]; NSDictionary *dataValues = [json objectWithString:responseString error:&errorOnParsing]; [responseString release]; if(errorOnParsing != nil) { //TODO: We have to send the website a feedback that there is some problem on the server end. dataObject.hasError = YES; dataObject.erorrMessage = @"Error on parsing, the server returned invalid data."; return dataObject; } dataObject.hasError = NO; dataObject.dataValues = dataValues; return dataObject; } @end Now when I build I got an error in the DataManager header where I #import Dataobject header, it says "error: expected')' before DataObject" I don;t understand what I miss. Thanks for the help..

    - by Comma
    I'm developing a reader app for viewing and highlighting proprietary format documents. The documents are 2D.

(Things I need to consider, tutorials, sample projects...) THX

  • check if sqlserver is installed on a machine thro C#

    - by Skun
    Hey ! I am making an application which is a user interface to access 2 types of databases - SQLite and MSSQL server. The thing is, SQLite doesnt need to be "installed" since its just a flatfile database, but on the other hand, SQLserver (Express/normal) need to be installed before use. My Question is simple: Is there a way by which i can find out if an instance of SQLserver has been installed on the local machine by using a C# program?

  • Combining foreach and using

    - by apoorv020
    I'm iterating over a ManageObjectCollection.( which is part of WMI interface). However the important thing is, the following line of code. : foreach (ManagementObject result in results) { //code here } The point is that ManageObject also implements IDisposable, so I would like to put "result" variable in a using block. Any idea on how to do this, without getting too weird or complex?

  • 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

  • Visual Basic and C++

    - by Hamdy Elgammal
    Hello there, I was reading a little into Visual Basic and it seemed a rather simple way to implement some GUI...So I was looking for a way to interface my C++ code to a Visual Basic snippet of code. For example, receive input from a Visual Basic app and send it over to C++ code to continue the logic of the program based on the input of that event.

  • Formatting dates when serialising an object in C# (2.0)

    - by zoman
    Hi, I'm xml-serializing a object with a large number of properties and I have two properties with DateTime types. I'd like to format the dates for the serialized output. I don't really want to implement the ISerializable interface and overwrite the serialization for every property. Is there any other way to achieve this? (I'm using C#, .NET 2) Thanks.

    - 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.
