• Best practices for creating a logger library using log4net. Is

  - by VolleyBall Player

  My goal is to create a log4net library that can be shared across multiple projects. In my solution which is in .net 4.0, I created a class library called Logger and referenced it from web project. Now I created a logger.config in the class library and put all the configuration in the logger.config file. I then used [assembly: log4net.Config.XmlConfigurator(Watch = true, ConfigFile = "Logger.config")] When I run the web app nothing is getting logged. So I added this line of code in web.config <add key="log4net.Internal.Debug" value="true"/> which gave me debugging info and error information Failed to find configuration section 'log4net' in the application's .config file. Check your .config file for the and elements. The configuration section should look like: I moved the configuration from logger.config to web.config and everything seems to work fine. I don't want the log4net configuration in web.config but have it logger.config as a cleaner approach. The goal is to make other projects use this library and not have to worry about configuration in every project. Now the question is, How do I do this? What am I doing wrong? Any suggestion with code example will be beneficial to everyone. FYI, I am using structure map IOC to reslove the logger before logging to it.

• How to get the value of an XML element using Linq even when empty.

  - by Yeodave

  Please excuse my stupidity, I tend to find the traversing XML overly complicated. I am using ASP.NET in VB. I have an XML document which contains all the details of staff in my company... <staff> <staffName>Test Staff</staffName> <staffTitle>Slave</staffTitle> <staffDepartmentName>Finance</staffDepartmentName> <staffOffice>London</staffOffice> <staffEmail>[email protected]</staffEmail> <staffPhone>0207 123 456</staffPhone> <staffNotes>Working hours Mon to Thurs 9.15 - 5.15</staffNotes> <staffBio></staffBio> </staff> As you can see, some nodes do not always contain data for ever member of staff; only Directors have biographies. I access the values like this... For Each staff In ( _ From matches In myXMLFile.Descendants("staff").Descendants("staffName") _ Where matches.Nodes(0).ToString.ToLower.Contains(LCase(search)) _ Order By matches.Value _ Select matches) staffName = staff.Descendants("staffName").Nodes(0).ToString) staffTitle = staff.Descendants("staffTitle").Nodes(0).ToString) staffOffice = staff.Descendants("staffOffice").Nodes(0).ToString) staffEmail = staff.Descendants("staffEmail").Nodes(0).ToString) staffPhone = staff.Descendants("staffPhone").Nodes(0).ToString) staffNotes = staff.Descendants("staffNotes").Nodes(0).ToString) staffBio = staff.Descendants("staffBio").Nodes(0).ToString) ' Do something with that data... Next Once it gets to staffBio I get an error saying "Object reference not set to an instance of an object." obviously because that node does not exist. My question is how can I assign the value to a variable even when it is empty without having to do a conditional check before each assignment?

• dotNet Templated, Repeating, Databound ServerControl: Counting the templates OnDataBind?

  - by Campbeln

  I have a server control that wraps an underlying class which manages a number of indexes to track where it is in a dataset (ie: RenderedRecordCount, ErroredRecordCount, NewRecordCount, etc.). I've got the server control rendering great, but OnDataBinding I'm having an issue as to seems to happen after CreateChildControls and before Render (both of which properly manage the iteration of the underlying indexes). While I'm somewhat familiar with the ASP.NET page lifecycle, this one seems to be beyond me at the moment. So... how do I hook into the iterative process OnDataBinding uses so I can manage the underlying indexes? Will I have to iterate over the ITemplates myself, managing the indexes as I go or is there an easier solution? Also... I implemented the iteration of the underlying indexes during CreateChildControls originally in the belief that was the proper place to hook in for events like OnDataBinding (thining it was done as the controls were being .Add'd). Now it seems that this may actually be unnecessary. So I guess the secondary question is: What happens during CreateChildControls? Are the unadulterated (read: with <%-tags in place) controls added to the .Controls collection without any other processing?

• C# InternalsVisibleTo() attribute for VBNET 2.0 while testing?

  - by Will Marcouiller

  I'm building an Active Directory wrapper in VBNET 2.0 (can't use later .NET) in which I have the following: IUtilisateur IGroupe IUniteOrganisation These interfaces are implemented in internal classes (Friend in VBNET), so that I want to implement a façade in order to instiate each of the interfaces with their internal classes. This will allow the architecture a better flexibility, etc. Now, I want to test these classes (Utilisateur, Groupe, UniteOrganisation) in a different project within the same solution. However, these classes are internal. I would like to be able to instantiate them without going through my façade, but only for these tests, nothing more. Here's a piece of code to illustrate it: public static class DirectoryFacade { public static IGroupe CreerGroupe() { return new Groupe(); } } // Then in code, I would write something alike: public partial class MainForm : Form { public MainForm() { IGroupe g = DirectoryFacade.CreerGroupe(); // Doing stuff with instance here... } } // My sample interface: public interface IGroupe { string Domaine { get; set; } IList<IUtilisateur> Membres { get; } } internal class Groupe : IGroupe { private IList<IUtilisateur> _membres; internal Groupe() { _membres = new List<IUtilisateur>(); } public string Domaine { get; set; } public IList<IUtilisateur> Membres { get { return _membres; } } } I heard of InternalsVisibleTo() attribute, recently. I was wondering whether it is available in VBNET 2.0/VS2005 so that I could access the assmebly's internal classes for my tests? Otherwise, how could I achieve this?

• Why my oracleParameter doesnt work?

  - by user1824356

  I'm a .NET developer and this is the first time i work with oracle provider (Oracle 10g and Framework 4.0). When i add parameter to my command in this way: objCommand.Parameters.Add("pc_cod_id", OracleType.VarChar, 4000).Value = codId; objCommand.Parameters.Add("pc_num_id", OracleType.VarChar, 4000).Value = numId; objCommand.Parameters.Add("return_value", OracleType.Number).Direction = ParameterDirection.ReturnValue; objCommand.Parameters.Add("pc_email", OracleType.VarChar, 4000).Direction = ParameterDirection.Output; I have no problem with the result. But when a add parameter in this way: objCommand.Parameters.Add(CreateParameter(PC_COD_ID, OracleType.VarChar, codId, ParameterDirection.Input)); objCommand.Parameters.Add(CreateParameter(PC_NUM_ID, OracleType.VarChar, numId, ParameterDirection.Input)); objCommand.Parameters.Add(CreateParameter(RETURN_VALUE, OracleType.Number, ParameterDirection.ReturnValue)); objCommand.Parameters.Add(CreateParameter(PC_EMAIL, OracleType.VarChar, ParameterDirection.Output)); The implementation of that function is: protected OracleParameter CreateParameter(string name, OracleType type, ParameterDirection direction) { OracleParameter objParametro = new OracleParameter(name, type); objParametro.Direction = direction; if (type== OracleType.VarChar) { objParametro.Size = 4000; } return objParametro; } All my result are a empty string. My question is, these way to add parameters are not the same? And if no, what is the difference? Thanks :) Add: Sorry i forgot mention "CreateParameter" is a function with multiple implementations the base is the above function, the other use that. protected OracleParameter CreateParameter(string name, OracleType type, object value, ParameterDirection direction) { OracleParameter objParametro = CreateParameter(name, type, value); objParametro.Direction = direction; return objParametro; } The last parameters doesn't need value because those are output parameter, those bring me data from the database.

• Implementing search functionality with multiple optional parameters against database table.

  - by quarkX

  Hello, I would like to check if there is a preferred design pattern for implementing search functionality with multiple optional parameters against database table where the access to the database should be only via stored procedures. The targeted platform is .Net with SQL 2005, 2008 backend, but I think this is pretty generic problem. For example, we have customer table and we want to provide search functionality to the UI for different parameters, like customer Type, customer State, customer Zip, etc., and all of them are optional and can be selected in any combinations. In other words, the user can search by customerType only or by customerType, customerZIp or any other possible combinations. There are several available design approaches, but all of them have some disadvantages and I would like to ask if there is a preferred design among them or if there is another approach. Generate sql where clause sql statement dynamically in the business tier, based on the search request from the UI, and pass it to a stored procedure as parameter. Something like @Where = ‘where CustomerZip = 111111’ Inside the stored procedure generate dynamic sql statement and execute it with sp_executesql. Disadvantage: dynamic sql, sql injection Implement a stored procedure with multiple input parameters, representing the search fields from the UI, and use the following construction for selecting the records only for the requested fields in the where statement. WHERE (CustomerType = @CustomerType OR @CustomerType is null ) AND (CustomerZip = @CustomerZip OR @CustomerZip is null ) AND ………………………………………… Disadvantage: possible performance issue for the sql. 3.Implement separate stored procedure for each search parameter combinations. Disadvantage: The number of stored procedures will increase rapidly with the increase of the search parameters, repeated code.

• Why doesn't AJAX History work in IE7 as it does in IE8 and every other browser?

  - by Nick

  I have two ASP.NET pages, say page1 and page2. Page1 contains an update panel and I use AJAX History to allow browser back/forward button support. Users can navigate to page2 via page1 - I do a response.redirect server-side so that I can store in a session what options were on page1 when they left. On page2, a user can click the back button and return to page1 with it displaying what was there prior to navigating to page2. You can click the back button again on page1 to go back to other selectively chosen history states. This all works great in IE8, Firefox, Safari, and Chrome. However, in IE7 it doesn't. The user can get back to page1 from page2, but when they click the back button again it doesn't show the previous states of page1 - it displays the original page load content. The history data looks to still be encoded in the url when using ie7 but is not working for some reason. Does anyone know why this is happening in IE7 and how I can get around this? It really needs to work in IE7 as most of our users are on IE7. Please help.

• Using mod_rewrite for a RESTful api

  - by razass

  Say the user is making a request to the following url: "http://api.example.com/houses/123/abc" That request needs to map to "/webroot/index.php" and 'houses', '123', 'abc' need to be able to be parsed out of the URL in that index.php. It also can't alter the http headers or body. There can be any number of variables after the domain ie) "http://api.example.com/houses/1234/abc/zxy/987" I think I already have all requests being sent to webroot using: <IfModule mod_rewrite.c> RewriteEngine on RewriteCond $0 !^webroot/ RewriteRule .* webroot/$0 [L] </IfModule> Which appears to be working but I am not sure if it is correct. But now I am at a loss as to how to take the next step as mentioned above. Thanks in advance!

• Recommend a Rackspace Cloud Server API Language Binding?

  - by Alex R

  Rackspace publishes only a hard-to-use HTTP and JSON/XML based "API" (they call it an API but it's really a non-standard Web Service without a WSDL). There are dozens of open-source language bindings to choose from. I have tried three of them so far and they're all horrible (incomplete, buggy, and/or undocumented). Can anybody recommend a language binding which is reasonably complete, well documented, and bug-free? I can use Perl, Python, PHP, or Java. My ultimate objective is to create a script/program that will provision a server, launch a process inside it, wait for the process to finish, copy the results to the local server, and destroy the remote server. What's the best choice for that? Thanks

• Building Interactive User Interfaces with Microsoft ASP.NET AJAX: Refreshing An UpdatePanel With Jav

  The ASP.NET AJAX UpdatePanel provides a quick and easy way to implement a snappier, AJAX-based user interface in an ASP.NET WebForm. In a nutshell, UpdatePanels allow page developers to refresh selected parts of the page (instead of refreshing the entire page). Typically, an UpdatePanel contains user interface elements that would normally trigger a full page postback - controls like Buttons or DropDownLists that have their AutoPostBack property set to True. Such controls, when placed inside an UpdatePanel, cause a partial page postback to occur. On a partial page postback only the contents of the UpdatePanel are refreshed, avoiding the "flash" of having the entire page reloaded. (For a more in-depth look at the UpdatePanel control, refer back to the Using the UpdatePanel installment in this article series.) Triggering a partial page postback refreshes the contents within an UpdatePanel, but what if you want to refresh an UpdatePanel's contents via JavaScript? Ideally, the UpdatePanel would have a client-side function named something like Refresh that could be called from script to perform a partial page postback and refresh the UpdatePanel. Unfortunately, no such function exists. Instead, you have to write script that triggers a partial page postback for the UpdatePanel you want to refresh. This article looks at how to accomplish this using just a single line of markup/script and includes a working demo you can download and try out for yourself. Read on to learn more!

• How to achieve a loosely coupled REST API but with a defined and well understood contract?

  - by BestPractices

  I am new to REST and am struggling to understand how one would properly design a REST system to both allow for loose coupling but at the same time allow a consumer of a REST API to understand the API. If, in my client code, I issue a GET request for a resource and get back XML, how do I know what to do with that xml? e.g. if it contains <fname>John</fname><lname>Smith</lname> how do I know that these refer to the concept of "first name", "last name"? Is it up to the person writing the REST API to define in documentation some place what each of the XML fields mean? What if producer of the API wants to change the implementation to be <firstname> instead of <fname>? How do they do this and notify their consumers that this change occurred? Or do the consumers just encounter the error and then look at the payload and figure out on their own that it changed? I've read in REST in Practice that using a WADL tool to create a client implementation based on the WADL (and hide the fact that you're doing a distributed call) is an "anti-pattern". But I was planning to do this-- at least then I would have a statically typed API call that, if it changed, I would know at compile time and not at run time. Why is this a bad thing to generate client code based on a WADL? And how do I know what to do with the links that returned in the response of a POST to a REST API? What defines this contract and gives true meaning to what each link will do? Please help! I dont understand how to go from statically-typed or even SOAP/RPC to REST!

• Performing client-side OAuth authorized Twitter API calls versus server side, how much of a difference is there in terms of performance?

  - by Terence Ponce

  I'm working on a Twitter application in Ruby on Rails. One of the biggest arguments that I have with other people on the project is the method of calling the Twitter API. Before, everything was done on the server: OAuth login, updating the user's Twitter data, and retrieving tweets. Retrieving tweets was the heaviest thing to do since we don't store the tweets in our database, so viewing the tweets means that we have to call the API every time. One of the people in the project suggested that we call the tweets through Javascript instead to lessen the load on the server. We used GET search, which, correct me if I'm wrong, will be removed when v1.0 becomes completely deprecated, but that really isn't a concern now. When the Twitter API has migrated completely to v1.1 (again, correct me if I'm wrong), every calls to the API must be authenticated, so we have to authenticate our Javascript requests to the API. As said here: We don't support or recommend performing OAuth directly through Javascript -- it's insecure and puts your application at risk. The only acceptable way to perform it is if you kept all keys and secrets server-side, computed the OAuth signatures and parameters server side, then issued the request client-side from the server-generated OAuth values. If we do exactly what Twitter suggests, the only difference between this and doing everything server-side is that our server won't have to contact the Twitter API anymore every time the user wants to view tweets. Here's how I would picture what's happening every time the user makes a request: If we do it through Javascript, it would be harder on my part because I would have to create the signatures manually for every request, but I will gladly do it if the boost in performance is worth all the trouble. Doing it through Ruby on Rails would be very easy since the Twitter gem does most of the grunt work already, so I'm really encouraging the other people in the project to agree with me. Is the difference in performance trivial or is it significant enough to switch to Javascript?

• Too complex/too many objects?

  - by Mike Fairhurst

  I know that this will be a difficult question to answer without context, but hopefully there are at least some good guidelines to share on this. The questions are at the bottom if you want to skip the details. Most are about OOP in general. Begin context. I am a jr dev on a PHP application, and in general the devs I work with consider themselves to use many more OO concepts than most PHP devs. Still, in my research on clean code I have read about so many ways of using OO features to make code flexible, powerful, expressive, testable, etc. that is just plain not in use here. The current strongly OO API that I've proposed is being called too complex, even though it is trivial to implement. The problem I'm solving is that our permission checks are done via a message object (my API, they wanted to use arrays of constants) and the message object does not hold the validation object accountable for checking all provided data. Metaphorically, if your perm containing 'allowable' and 'rare but disallowed' is sent into a validator, the validator may not know to look for 'rare but disallowed', but approve 'allowable', which will actually approve the whole perm check. We have like 11 validators, too many to easily track at such minute detail. So I proposed an AtomicPermission class. To fix the previous example, the perm would instead contain two atomic permissions, one wrapping 'allowable' and the other wrapping 'rare but disallowed'. Where previously the validator would say 'the check is OK because it contains allowable,' now it would instead say '"allowable" is ok', at which point the check ends...and the check fails, because 'rare but disallowed' was not specifically okay-ed. The implementation is just 4 trivial objects, and rewriting a 10 line function into a 15 line function. abstract class PermissionAtom { public function allow(); // maybe deny() as well public function wasAllowed(); } class PermissionField extends PermissionAtom { public function getName(); public function getValue(); } class PermissionIdentifier extends PermissionAtom { public function getIdentifier(); } class PermissionAction extends PermissionAtom { public function getType(); } They say that this is 'not going to get us anything important' and it is 'too complex' and 'will be difficult for new developers to pick up.' I respectfully disagree, and there I end my context to begin the broader questions. So the question is about my OOP, are there any guidelines I should know: is this too complicated/too much OOP? Not that I expect to get more than 'it depends, I'd have to see if...' when is OO abstraction too much? when is OO abstraction too little? how can I determine when I am overthinking a problem vs fixing one? how can I determine when I am adding bad code to a bad project? how can I pitch these APIs? I feel the other devs would just rather say 'its too complicated' than ask 'can you explain it?' whenever I suggest a new class.

  I've recently coded a .NET Console app using C#. It's purpose was to read the emails within a specific folder, parse them for specific values and save them to a database. Our email system, at the time I originally coded this, was Exchange 2003. However, I was made aware we would soon be upgrading to Exchange 2010: ergo, I built the code to work in both environments. Following the migration to 2010, however, the app has broken. The app uses the EWS API for 2010 functionality. When it attempts to use the ExchangeService's FindFolders method to find the publicfoldersroot, it throws an exception. Here's the code: ExchangeService service = new ExchangeService(); FindFoldersResults findRootFldrs; service.UseDefaultCredentials = true; service.AutodiscoverUrl("[email protected]", delegate(string x) { return true; }); FolderView fview = new FolderView(100); fview.Traversal = FolderTraversal.Deep; if (findRootFldrsSub == null) { //Set to root to test local folders -- findRootFldrs = service.FindFolders(WellKnownFolderName.PublicFoldersRoot, fview); } The exception: "The mailbox that was requested doesn't support the specified RequestServerVersion" I've attempted: -Setting the exchangeservice to 2007 (throws an exception: "An internal server error occurred. The operation failed.") -Giving myself the highest level of permission to the Public Folder (no effect) -Manually setting my credentials (no effect) I can view the public folders in outlook; the publicfoldersroot property is available in the intellisense; the code works on local folders (I can parse my inbox). My current thinking is that it's a setting on the recent setup of Exchange 2010: unfortunately that isn't really my field.

• Decompiling a *.DLL to assembly for .net in delphi 4

  - by Lex Dean

  I love my Delphi 4 but at the same time I see the need to talk to windows .net This is a recompiled dll that I found on sourceforge.net/projects/delphinet/ (DelphiNet03.zip) by some nice people that fund the dll from some were. The real answer is to make this dll so that fits into Delphi as true Delphi code, and not a dll clip on. So we can make objects that use dot net in Delphi. Because I’m not an assembly freak, I’m freaking out a little with a wee sweek for help! 1/ How do I link the asm code with the data info at the bottom of this code. Can some one show me which calls to look for to make this link to data. 2/ I need to find the beginning of all the procedures and functions, but I cannot find a ‘RET’ statement. And what line is the beginning statement in this code. 3/ How do I identify were the jump statements go to, put them into Delphi format In this code it looks I can do:- jle 402890h \1000:00402854 7e3a add [eax], al \1000:00402856 0000 …………………………………………….. or ch, [edi+3eh] \1000:0040288d 0a6f3e xrefs first: 1000:00402854 number : 1 \; add [eax], al \1000:00402890 0000 //******************************* jle @@21 \\1000:00402854 7e3a add [eax], al \\1000:00402856 0000 …………………………………………….. or ch, [edi+3eh] \1000:0040288d 0a6f3e xrefs first: 1000:00402854 number : 1 \; @@21 add [eax], al \1000:00402890 0000 Is that a correct conversion. I think a xrefs first: 1000:004021d1 number : 1 is the best to follow 4/ I need a good reference on 8086 up assembly code that I can print out and get to learn properly. I found this asm decomplier of http://www.cronos.cc/ that is so similar to Delphi that it only needs a little more convertion to get it into Delphi asm I think. It’s only taken me 3 hours to get the file into TMemo and to write a few lines to chop the line over in a stream and reload the memo.

• .NET projects build automation with NAnt/MSBuild + SVN

  - by petr k.

  Hi everyone, for quite a while now, I've been trying to figure out how to setup an automated build process at our shop. I've read many posts and guides on this matter and none of them really fits my specifics needs. My SVN repository is laid out as follows \projects \projectA (a product) \tags \1.0.0.1 \1.0.0.2 ... \trunk \src \proj1 (a VS C# project) \proj2 \documentation Then I have a network share, with a folder for each project (product), which in turn contains the binaries, written documentation and the generated API documentation (via NDoc - each project may have an .ndoc file in the repository) for every historical version (from the tags SVN folder) and for the latest version as well (from the trunk). Basically, what I want to do in a scheduled batch build are these steps: examine the project's SVN folder and identify tags not present in the network share for each of these tags check out the tag folder build (with Release config) copy the resulting binaries to the network share search for .ndoc files generate CHM files via NDoc copy the resulting CHM files to the network share do the same as in 2., but for the HEAD revision of trunk Now, the trouble is, I have no idea where to start. I do not keep .sln files in the repository, but I am able to replace these with MSBuild files which in turn build the C# projects belonging to the specific product. I guess the most troubling part is the examination of the repository for tags which have not been processed yet - i.e. searching the tags and comparing them to a project's directory structure on the network share. I have no idea how to do that in any of the build tools (NAnt, MSBuild). Could you please provide me with some pointers on how to approach this task as a whole and in detail as well? I do not care if I use NAnt, MSBuild, or both. I am aware that this might be rather complex, but every idea and NAnt/MSBuild snippet will be a great help. Thanks in advance.

• Problem with reCaptcha and .NET

  - by vtortola

  Hi, I get this error with reCaptcha: 'Input error: response: Required field must not be blank challenge: Required field must not be blank privatekey: Required field must not be blank' I'm sending the data via POST, so I don't understand what is going on. This is the code I use: public static Boolean Check(String challenge, String response) { try { String privatekey = "7LeAbLoSAAAABJBn05uo6sZoFNoFnK2XKyF3dRXL"; String remoteip = HttpContext.Current.Request.UserHostAddress; WebRequest req = WebRequest.Create("http://api-verify.recaptcha.net/verify"); req.Method = "POST"; using (StreamWriter sw = new StreamWriter(req.GetRequestStream())) { sw.Write("privatekey={0}&remoteip={1}&challenge={2}&response={3}", privatekey, remoteip, challenge, response); sw.Flush(); } String resultString = String.Empty; String errorString = String.Empty; using (StreamReader sr = new StreamReader(req.GetResponse().GetResponseStream())) { resultString = sr.ReadLine(); errorString = sr.ReadLine(); } Boolean b; return Boolean.TryParse(resultString, out b) && b; } catch (Exception) { return false; } } (Of course that'is not the correct private key :P) I have no idea what the problem is about, I think I'm sending the data correctly, but that error says that apparently I'm not sending anything. What could be the problem? Cheers.

• Wrapping mailmessage headers in .net for Sendgrid

  - by mickyjtwin

  Am using SendGrid for some email notifications, specifically utilising their SMTP API's. While they have PHP examples, c# is not so helpful. Essentially, a json string is built that contains the to email addresses, and other custom filters etc, which is then added to a MailMessage header to send. // json string example {"to":["[email protected]", [email protected]", "", ""],"sub":{"<name>":["Name1", Name2"]}} MailMessage m = new MailMessage("[email protected]", "[email protected]"); m.Headers.Add("X-SMTPAPI", jsonString); The problem I am having is that for some MTA's, headers can only be 1000 characters long, and also quoted-principle encoding required only 76 character per line. In their php example, they are splitting the string and adding a linebreak (\n) every 72 characters. While I am doing this in .NET, I am receiving a invalid character exception. After some digging, it seems that pre-.NET4.0 Beta2 MailMessage will not process CLLR characters. Sengrid support is not proving helpful, and looking at ways to make this work?

• How to mimic built-in .NET serialization idioms?

  - by Matt Enright

  I have a library (written in C#) for which I need to read/write representations of my objects to disk (or to any Stream) in a particular binary format (to ensure compatibility with C/Java library implementations). The format requires a fair amount of bit-packing and some DEFLATE'd bytestreams. I would like my library, however, to be as idiomatic .NET as possible, however, and so would like to provide an API as close as possible to the normal binary serialization process. I'm aware of the ability to implement the IFormatter interface, but being that I really am unable to reuse any part of the built-in serialization stack, is it worth doing this, or will it just bring unnecessary overhead. In other words: Implement IFormatter and co. OR Just provide "Serialize"/"Deserialize" methods that act on a Stream? A good point brought up below about needing the serialization semantics for any case involving Remoting. In a case where using MarshalByRef objects is feasible, I'm pretty sure that this won't be an issue, so leaving that aside are there any benefits or drawbacks to using the ISerializable/IFormatter versus a custom stack (or, is my understanding remoting incorrectly)?

• Most unintuitive behaviour in the .Net framework?

  - by BlueRaja

  Intended behavior is often another phrase for bug-which-we-knew-about-when-we-wrote-it, but-we-wrote-it-anyways. Because it was "intended" (or perhaps it is now too late or too difficult), many of these extremely-unintuitive bugs never get fixed. For instance, consider the following code (C#): TextInfo textInfo = Thread.CurrentThread.CurrentCulture.TextInfo; textInfo.ToTitleCase("hello world!"); //Returns "Hello World!" textInfo.ToTitleCase("hElLo WoRld!"); //Returns "Hello World!" textInfo.ToTitleCase("Hello World!"); //Returns "Hello World!" What would you expect textInfo.ToTitleCase("HELLO WORLD!"); to return? In fact, it returns "HELLO WORLD!". This was well-documented "intended behavior," but, in my eyes, is extremely unintuitive, and therefore a bug. What is some other unintuitive behavior like this in this in the .Net framework? Bonus points if you can provide a fix that does not break backwards-compatibility. Remember! Always keep these two simple rules in mind when designing an API (or anything else): Make the common case the default, and Keep It Simple, Stupid!

• ASP.NET MVC 3 embrace dynamic type - CSDN.NET - CSDN Software Development Channel

  - by user559071

  About a decade ago, Microsoft will all bet on the WebForms and static types. With the complete package from scattered to the continuous development, and now almost every page can be viewed as its own procedure. Subsequent years, the industry continued to move in another direction, love is better than separation package, better than the late binding early binding to the idea. This leads to two very interesting questions. The first is the problem of terminology. Consider the original Smalltalk MVC model, view and controller is not only tightly coupled together, and usually in pairs. Most of the framework is that Microsoft, including the classic VB, WinForms, WebForms, WPF and Silverlight, they both use the code behind file to store the controller logic. But said "MVC" usually refers to the view and controller are loosely coupled framework. This is especially true for the Web framework, HTML form submission mechanism allows any views submitted to any of the controller. Since this article was mainly talking about Web technologies, so we need to use the modern definition. The second question is "If you're Microsoft, how to change orbit without causing too much pressure to the developer?" So far, the answer is: new releases each year, until the developers meet up. ASP.NET MVC's first product was released last March. Released in March this year, ASP.NET MVC 2.0. 3.0 RC 2 is currently in phase, expected to be released next March. December 10, Microsoft released ASP.NET MVC 3.0 Release Candidate 2. RC 2 is built on top of Microsoft's commitment to the jQuery: The default project template into jQuery 1.4.4, jQuery Validation 1.7 and jQuery UI. Although people think that Microsoft will focus shifted away from server-side controls to be a joke, but the introduction of Microsoft's jQuery UI is that this is the real thing. For those worried about the scalability of the developers, there are many excellent control can replace the session state. With SessionState property, you can tell the controller session state is read-only, read-write, or can be completely ignored in the. This site is no single server, but if a server needs to access another server session state, then this approach can provide a great help. MVC 3 contains Razor view engine. By default, the engine will be encoded HTML output, so that we can easily output on the screen the text of the original. HTML injection attacks even without the risk of encoded text can not easily prevent the page rendering. For many C # developers in the end do what is most shocking that MVC 3 for the controller and view and embrace the dynamic type. ViewBag property will open a dynamic object, developers can run on top of the object to add attributes. In general, it is used to send the view from the controller non-mode data. Scott Guthrie provides state of the sample contains text (such as the current time) and used to assemble the list box entries.

• Deploying MVC2 application to IIS7.5 - Ninject asked to provide controllers for content files

  - by Rune Jacobsen

  I have an application that started life as an MVC (1.0) app in Visual Studio 2008 Sp1 with a bunch of Silverlight 3 projects as part of the site. Nothing fancy at all. Using Ninject for dependency injection (first version 2 beta, now the released version 2 with the MVC extensions). With the release of .Net 4.0, VS2010, MVC2 etc., we decided to move the application to the newest platform. The conversion wizard in VS2010 apparently took care of everything, with one exception - it didn't change references to mvc1 to now point to mvc2, so I had to do that manually. Of course, this makes me think about other MVC2 things that could be missing from my app, that would be there if I did File - New Project... But that is not the focus of this question. When I deploy this application to the IIS 7.5 server (running on Win2008 R2 x64), the application as such works. However, images, scripts and other static content doesn't seem to exist. Of course they are there on disk on the server, but they don't show up in the client web browser. I am fairly new to IIS, so the only trick I knew is to try to open the web page in a browser on the server, as that could give me more information. And here, finally, we meet our enemy. If I try to go directly to the URL of one of the images (http://server/Content/someimage.jpg for instance), I get the following error in the browser: The IControllerFactory 'Ninject.Web.Mvc.NinjectControllerFactory' did not return a controller for a controller named 'Content'. Aha. The web server tries to feed this request to MVC, who with its' default routing setup assumes Content to be a controller, and fails. How can I get it to treat Content/ and Scripts/ (among others) as non-controllers and just pass through the static content? This of course works with Cassini on my developer machine, but as soon as I deploy, this problem hits. I am using the last version of Ninject MVC 2 where the IoC tool should pass missing controllers to the base controller factory, but this has apparently not helped. I have also tried to add ignore routes for Content etc., but this apparently has no effect either. I am not even sure I am addressing the problem on the right level. Does anyone know where to look to get this app going? I have full control of the web server so I can more or less do whatever I want to it, as long as it starts working. Thanks!

• protobuf-net: incorrect wire-type exception deserializing Guid properties

  - by Paul Smith

  I'm having issues deserializing certain Guid properties of ORM-generated entities using protobuf-net. Here's a simplified example of the code (reproduces most elements of the scenario, but doesn't reproduce the behavior; I can't expose our internal entities, so I'm looking for clues to account for the exception). Say I have a class, Account with an AccountID read-only guid, and an AccountName read-write string. I serialize & immediately deserialize a clone. Deserializing throws an Incorrect wire-type deserializing Guid exception while deserializing. Here's example usage... Account acct = new Account() { AccountName = "Bob's Checking" }; Debug.WriteLine(acct.AccountID.ToString()); using (MemoryStream ms = new MemoryStream()) { ProtoBuf.Serializer.Serialize<Account>(ms, acct); Debug.WriteLine(Encoding.UTF8.GetString(ms.GetBuffer())); ms.Position = 0; Account clone = ProtoBuf.Serializer.Deserialize<Account>(ms); Debug.WriteLine(clone.AccountID.ToString()); } And here's an example ORM'd class (simplified, but demonstrates the relevant semantics I can think of). Uses a shell game to deserialize read-only properties by exposing the backing field ("can't write" essentially becomes "shouldn't write," but we can scan code for instances of assigning to these fields, so the hack works for our purposes). Again, this does not reproduce the exception behavior; I'm looking for clues as to what could: [DataContract()] [Serializable()] public partial class Account { public Account() { _accountID = Guid.NewGuid(); } [XmlAttribute("AccountID")] [DataMember(Name = "AccountID", Order = 1)] public Guid _accountID; /// <summary> /// A read-only property; XML, JSON and DataContract serializers all seem /// to correctly recognize the public backing field when deserializing: /// </summary> [IgnoreDataMember] [XmlIgnore] public Guid AccountID { get { return this._accountID; } } [IgnoreDataMember] protected string _accountName; [DataMember(Name = "AccountName", Order = 2)] [XmlAttribute] public string AccountName { get { return this._accountName; } set { this._accountName = value; } } } XML, JSON and DataContract serializers all seem to serialize / deserialize these object graphs just fine, so the attribute arrangement basically works. I've tried protobuf-net with lists vs. single instances, different prefix styles, etc., but still always get the 'incorrect wire-type ... Guid' exception when deserializing. So the specific questions is, is there any known explanation / workaround for this? I'm at a loss trying to trace what circumstances (in the real code but not the example) could be causing it. We hope not to have to create a protobuf dependency directly in the entity layer; if that's the case, we'll probably create proxy DTO entities with all public properties having protobuf attributes. (This is a subjective issue I have with all declarative serialization models; it's a ubiquitous pattern & I understand why it arose, but IMO, if we can put a man on the moon, then "normal" should be to have objects and serialization contracts decoupled. ;-) ) Thanks!

• .NET SerialPort DataReceived event not firing

  - by Klay

  I have a WPF test app for evaluating event-based serial port communication (vs. polling the serial port). The problem is that the DataReceived event doesn't seem to be firing at all. I have a very basic WPF form with a TextBox for user input, a TextBlock for output, and a button to write the input to the serial port. Here's the code: public partial class Window1 : Window { SerialPort port; public Window1() { InitializeComponent(); port = new SerialPort("COM2", 9600, Parity.None, 8, StopBits.One); port.DataReceived += new SerialDataReceivedEventHandler(port_DataReceived); port.Open(); } void port_DataReceived(object sender, SerialDataReceivedEventArgs e) { Debug.Print("receiving!"); string data = port.ReadExisting(); Debug.Print(data); outputText.Text = data; } private void Button_Click(object sender, RoutedEventArgs e) { Debug.Print("sending: " + inputText.Text); port.WriteLine(inputText.Text); } } Now, here are the complicating factors: The laptop I'm working on has no serial ports, so I'm using a piece of software called Virtual Serial Port Emulator to setup a COM2. VSPE has worked admirably in the past, and it's not clear why it would only malfunction with .NET's SerialPort class, but I mention it just in case. When I hit the button on my form to send the data, my Hyperterminal window (connected on COM2) shows that the data is getting through. Yes, I disconnect Hyperterminal when I want to test my form's ability to read the port. I've tried opening the port before wiring up the event. No change. I've read through another post here where someone else is having a similar problem. None of that info has helped me in this case. EDIT: Here's the console version (modified from http://mark.michaelis.net/Blog/TheBasicsOfSystemIOPortsSerialPort.aspx): class Program { static SerialPort port; static void Main(string[] args) { port = new SerialPort("COM2", 9600, Parity.None, 8, StopBits.One); port.DataReceived += new SerialDataReceivedEventHandler(port_DataReceived); port.Open(); string text; do { text = Console.ReadLine(); port.Write(text + "\r\n"); } while (text.ToLower() != "q"); } public static void port_DataReceived(object sender, SerialDataReceivedEventArgs args) { string text = port.ReadExisting(); Console.WriteLine("received: " + text); } } This should eliminate any concern that it's a Threading issue (I think). This doesn't work either. Again, Hyperterminal reports the data sent through the port, but the console app doesn't seem to fire the DataReceived event. EDIT #2: I realized that I had two separate apps that should both send and receive from the serial port, so I decided to try running them simultaneously... If I type into the console app, the WPF app DataReceived event fires, with the expected threading error (which I know how to deal with). If I type into the WPF app, the console app DataReceived event fires, and it echoes the data. I'm guessing the issue is somewhere in my use of the VSPE software, which is set up to treat one serial port as both input and output. And through some weirdness of the SerialPort class, one instance of a serial port can't be both the sender and receiver. Anyway, I think it's solved.
