  • Where do I find a list of changes and bug fixes for .Net classes from 3.5 -> 4.0?

    - by Nathan Ridley
    I'm having trouble finding a list of the changes and bug fixes that have been made in the .Net framework for .Net 4.0. They're not easy to find, but surely they exist somewhere? Specifically I want to find out what changes and updates have been made for System.Net.HttpWebRequest and System.Net.CookieContainer, as both are quite bugridden in 3.5 and I want to evaluate whether I should write my code for .Net 4.0 or if I should create some custom classes to work around their issues.

  • Using XStream to deserialize an XML response with separate "success" and "failure" forms?

    - by Chris Markle
    I am planning on using XStream with Java to convert between objects and XML requests and XML responses and objects, where the XML is flowing over HTTP/HTTPS. On the response side, I can get a "successful" response, which seems like it would map to one Java class, or a "failure" response, which seems like it would map to another Java class. For example, for a "file list" request, I could get an affirmative response e.g., <?xml version="1.0" encoding="UTF-8"?> <response> <success>true</success> <files> <file>[...]</file> <file>[...]</file> <file>[...]</file> </files> </response> or I could get a negative response e.g., <?xml version="1.0" encoding="UTF-8"?> <response> <success>false</success> <error> <errorCode>-502</errorCode> <systemMessage>[...]AuthenticationException</systemMessage> <userMessage>Not authenticated</userMessage> </error> </response> To handle this, should I include fields in one class for both cases or should I somehow use XStream to "conditionally" create one of the two potential classes? The case with fields from both response cases in the same object would look something like this: Class Response { boolean success; ArrayList<File> files; ResponseError error; [...] } Class File { String name; long size; [...] } Class ResponseError { int errorCode; String systemMessage; String userMessage; [...] } I don't know what the "use XStream and create different objects in case of success or error" looks like. Is it possible to do that somehow? Is it better or worse way to go? Anyway, any advice on how to handle using XStream to deal with this success vs. failure response case would be appreciated. Thanks in advance!

  • Error Serializing a CLR object for use in a WCF service

    - by user208662
    Hello, I have written a custom exception object. The reason for this is I want to track additional information when an error occurs. My CLR object is defined as follows: public class MyException : Exception { public override string StackTrace { get { return base.StackTrace; } } private readonly string stackTrace; public override string Message { get { return base.Message; } } private readonly string message; public string Element { get { return element; } } private readonly string element; public string ErrorType { get { return errorType; } } private readonly string errorType; public string Misc { get { return misc; } } private readonly string misc; #endregion Properties #region Constructors public MyException() {} public MyException(string message) : base(message) { } public MyException(string message, Exception inner) : base(message, inner) { } public MyException(string message, string stackTrace) : base() { this.message = message; this.stackTrace = stackTrace; } public MyException(string message, string stackTrace, string element, string errorType, string misc) : base() { this.message = message; this.stackTrace = stackTrace; this.element = element; this.errorType = errorType; this.misc = misc; } protected MyException(SerializationInfo info, StreamingContext context) : base(info, context) { element = info.GetString("element"); errorType = info.GetString("errorType"); misc = info.GetString("misc"); } public override void GetObjectData(SerializationInfo info, StreamingContext context) { base.GetObjectData(info, context); info.AddValue("element", element); info.AddValue("errorType", errorType); info.AddValue("misc", misc); } } I have created a copy of this custom xception in a WP7 application. The only difference is, I do not have the GetObjectData method defined or the constructor with SerializationInfo defined. If I run the application as is, I receive an error that says: Type 'My.MyException' cannot be serialized. Consider marking it with the DataContractAttribute attribute, and marking all of its members you want serialized with the DataMemberAttribute attribute. If the type is a collection, consider marking it with the CollectionDataContractAttribute. If I add the DataContract / DataMember attributes to the class and its appropriate members on the server-side, I receive an error that says: Type cannot be ISerializable and have DataContractAttribute attribute. How do I serialize MyException so that I can pass an instance of it to my WCF service. Please note, I want to use my service from an Android app. Because of this, I don't want to do anything too Microsoft centric. That was my fear with DataContract / DataMember stuff. Thank you so much for your help!

  • specifying classpath for built-in ant tasks

    - by carneades
    I use the classpath attribute in custom Ant tasks to tell Ant where to find the external task jar, but how do I do the same for built-in tasks? In my case I'd like to make sure ant uses my copy of jsch.jar for the scp task, and not one that my already be installed on the system. Is there any way I can <scp> while guaranteeing it's using my jsch.jar?

  • Php recursion into multidimensional array

    - by dclowd9901
    I'm trying to write a script that, in its process, would need to be able to write an undefined number of nested arrays, and those arrays need to be able to have custom keys. Essentially, the script is being used to convert an HTML DOM into a multidimensional array. I'm not extremely well versed in recursion, so any pointers would be awesome.

  • Creating Bitmaps from ARGB strings (in actionscript-3)???

    - by ashenwraith
    Hi, in actionscript 3, what's the fastest way to dump your data (not from a file) into a bitmap for display? I have it working with setPixels and colored rects but that's way too slow/inefficient. Is there a way to load in the raw bytes or hijack the loader class to put in custom loader data? What would be the best/fastest--should I start writing a byte encoder?

  • Can someone clarify what this Joel On Software quote means: (functional programs have no side effect

    - by Bob
    I was reading Joel On Software today and ran across this quote: Without understanding functional programming, you can't invent MapReduce, the algorithm that makes Google so massively scalable. The terms Map and Reduce come from Lisp and functional programming. MapReduce is, in retrospect, obvious to anyone who remembers from their 6.001-equivalent programming class that purely functional programs have no side effects and are thus trivially parallelizable. What does he mean when he says functional programs have no side effects? And how does this make parallelizing trivial?
