• How to analyse contents of binary serialization stream?

  - by Tao

  I'm using binary serialization (BinaryFormatter) as a temporary mechanism to store state information in a file for a relatively complex (game) object structure; the files are coming out much larger than I expect, and my data structure includes recursive references - so I'm wondering whether the BinaryFormatter is actually storing multiple copies of the same objects, or whether my basic "number of objects and values I should have" arithmentic is way off-base, or where else the excessive size is coming from. Searching on stack overflow I was able to find the specification for Microsoft's binary remoting format: http://msdn.microsoft.com/en-us/library/cc236844(PROT.10).aspx What I can't find is any existing viewer that enables you to "peek" into the contents of a binaryformatter output file - get object counts and total bytes for different object types in the file, etc; I feel like this must be my "google-fu" failing me (what little I have) - can anyone help? This must have been done before, right??

• jQuery keyup() illegal characters

  - by FFish

  I have a field and want to prevent some illegal characters while showing the user as he types. How can I do this in follow example? $('input').bind("change keyup", function() { var val = $(this).attr("value"); /* if (val --contains-- '"') { $(this).css("background", "red"); val = val.replace('"', ""); $(this).attr("value", val) } */ $("p").html(val); }); EDIT: I should put the illegal characters in an array var vowels = new Array('"', "<", ">", "&");

• Rtti for Variant Records

  - by Coco

  I try to write a kind of object/record serializer with Delphi 2010 and wonder if there is a way to detect, if a record is a variant record. E.g. the TRect record as defined in Types.pas: TRect = record case Integer of 0: (Left, Top, Right, Bottom: Longint); 1: (TopLeft, BottomRight: TPoint); end; As my serializer should work recursively on my data structures, it will descent on the TPoint records and generate redundant information in my serialized file. Is there a way to avoid this, by getting detailed information on the record?

• Solr date field tdate vs date?

  - by user550178

  So I have a question about Solr's field date types which is pretty straight forward: what's the difference between a 'date' field and a 'tdate' one? The schema .xml claims that 'For faster range queries, consider the tdate type' and 'A Trie based date field for faster date range queries and date faceting. ' Fair enough... but what's the precisionStep="6" all about? should i change this? does it change the way i would create the query in case I use the tdate? What's the real advantage or what does Solr do that makes it better? P.S went through google, Solr manual, solr wiki and the java docs without any luck so I'd appreciate a kind and explanatory answer :)...

• SSIS - Can I get the column schema for a flat file source from a database?

  - by Steve Clement

  We receive a nightly data export from a vendor in the form of about 10 tab-delimited flat file without column headers. In addition, the vendor provides us with the SQL scripts for the database tables so that we can import the files into our system. Unfortunately, the vendor recently changed the schema for the flat files. Each file has upwards 150 columns, and having to go through the DB schema and adjust column types on a Flat File Data Source in SSIS is extremely time consuming, not to mention a royal pain. Since I know the file data layout in the database schema, is there any way I can dynamically pull that into a Flat File source to set the columns correctly? Or am I just stuck with manually setting everything?

• How to show a client-side message with Java JSF/Tobago?

  - by Marcus

  I have a web application created with JSF and Tobago. The user types some date into a sheet and clicks a button (all within one sheet-row). Now my java class checks whether the data is correct or not. In case there are some problems, I would like to show up something like a messagebox containing the errormessage. I cannot use something like JDialog, since this would happen only server side. Every user independently of his location needs to get the message. I thought about setting the error information into a databean and having my jsp show up the message after reloading. But how can I achieve this? Is there something like a tag which can be used for this? Or can I use the "confirmation" facet for this? But how would I start it without having the user to do something? Thanks in advance!

• Missing Project Template after installing ASP.NET MVC 2

  - by DotNetHacker

  Hi, I have downloaded the ASP.NET MVC 2 Release version (using Web Platform Installer) as well as the downloading the file directly from the link in WPI. No error messages are reported after the install. When I go into Visual Web Developer and select Create New project I only the project reference to ASP.NET MVC version 1.0 and not version 2 (for clarity I have all the other project types, this is just in reference to the MVC projects). I have restarted, uninstalled and restarted and installed my PC multiple times and it still won't play. When clicking add a reference I can see the MVC.dll version 2.0.0.0 and add that no problem, but cannot manually upgrade the project since the ProjectTypeGuid used is not recognized. For reference I am using Visual Web Developer 2008 on Windows XP. ASP.NET MVC version 1.0 is working fine and without issue. Hope someone else can help. DNH

• Accepting drag operations in an NSCollectionView subclass

  - by andyvn22

  I've subclassed NSCollectionView and I'm trying to receive dragged files from the Finder. I'm receiving draggingEntered: and returning an appropriate value, but I'm never receiving prepareForDragOperation: (nor any of the methods after that in the process). Is there something obvious I'm missing here? Code: - (void)awakeFromNib { [self registerForDraggedTypes:[NSArray arrayWithObjects:NSFilenamesPboardType, nil]]; } - (NSDragOperation)draggingEntered:(id <NSDraggingInfo>)sender { NSLog(@"entered"); //Happens NSPasteboard *pboard; NSDragOperation sourceDragMask; sourceDragMask = [sender draggingSourceOperationMask]; pboard = [sender draggingPasteboard]; if ([[pboard types] containsObject:NSFilenamesPboardType]) { NSLog(@"copy"); //Happens return NSDragOperationCopy; } return NSDragOperationNone; } - (BOOL)prepareForDragOperation:(id <NSDraggingInfo>)sender { NSLog(@"prepare"); //Never happens return YES; }

• When does ref($variable) return 'IO'?

  - by Zaid

  Here's the relevant excerpt from the documentation of the ref function: The value returned depends on the type of thing the reference is a reference to. Builtin types include: SCALAR ARRAY HASH CODE REF GLOB LVALUE FORMAT IO VSTRING Regexp Based on this, I imagined that calling ref on a filehandle would return 'IO'. Surprisingly, it doesn't: use strict; use warnings; open my $fileHandle, '<', 'aValidFile'; close $fileHandle; print ref $fileHandle; # prints 'GLOB', not 'IO' perlref tries to explain why: It isn't possible to create a true reference to an IO handle (filehandle or dirhandle) using the backslash operator. The most you can get is a reference to a typeglob, which is actually a complete symbol table entry [...] However, you can still use type globs and globrefs as though they were IO handles. In what circumstances would ref return 'IO' then?

• Is this casting safe?

  - by Itsik

  I need to write a Util function (in my c++cli app) that converts a String to a Double or Float or Int. template<typename T> static T MyConvert(String^ str) { return static_cast<T>(System::Convert::ToDouble(str)); } Is this safe? Can it somehow convert 2 to 1.999 and then to 1 if I call MyConvert<int>("2") ? I was wondering why the Convert class isn't templated in the first place? (That would let me call Convert<T> instead of Convert.ToDouble() for all types) This is C++/Cli so I can use any convert methods in c++ or .net, but I only know Convert.ToDouble()|ToString()|ToInt32()) Thanks

• View artifacts leaking into the model of MVC

  - by Jono

  In an ASP.NET MVC application (which has very little chance of having its view technology ported to something non-HTML, but whose functional requirements evolve weekly,) how much HTML should ideally be allowed to be directly represented in the Model? I might come across as a design bigot for this, but I regard it as bad practice to allow any view constructs to "leak" into the model in an MVC application (and vice versa). For example, a Model that represents an item you're about to purchase should know nothing about the HTML check box that says "add giftwrap/message", nor should it know about any HTML drop down lists for payment card types. Conversely the View shouldn't be doing work like figuring out button text by translating keys into values (by looking in resource files.)

• Ideas for building vulnerabilities into your site?

  - by Jaco Pretorius

  I'm trying to create a programming challenge that would require developers to hack into the MVC site I create. The idea is obviously to teach them about preventing these types of attacks. The current idea I have is to build multiple vulnerabilities into the site - but the second vulnerability would require the first to be completed, etc. So I was thinking the first could be a sql injection attack, the second would require a modified GET request, etc. Exploiting the final vulnerability would reveal a specific piece of information which is proof that you have completed the entire challenge. This will not be deployed on a public site - it's simply a learning tool for developers at my company. I'm not looking for MVC-specific vulnerabilities - I'm simply using MVC because it allows me to work with the 'raw' HTML. Any ideas on the different vulnerabilities I can use?

• RIA Services - Two entity models share an entity name

  - by Alex

  I have two entity models hooked up to two different databases. However, the two databases both have a table named 'brand', for example. As such, there is a naming conflict in my models. Now, I've been able to add a namespace to each model, via Custom Tool Namespace in the model's properties, but the generated code in my Silverlight project will try to use both namespaces, and come up with this, Imports MyProject.ModelA Imports MyProject.ModelB Public ReadOnly Property brands() As EntitySet(Of brand) Get Return MyBase.EntityContainer.GetEntitySet(Of brand) End Get End Property giving me this exception: 'Error 1 'brand' is ambiguous, imported from the namespaces or types 'MyProject.ModelA,MyProject.ModelB'. Has anyone had experience with naming conflicts like this using RIA services? How did you solve it?

• Cache whole result set or based on user ?

  - by eugeneK

  In my web application i have statistics which shown for each user separately ie. posts made , posts made today , articles started by and so on... Each user has his own special statistics. What is more flexible and "right" to work with one huge DataTable in Cache with whole data from all users and then loop thought DataTable to find certain user data or to cache each user ie. cacheObj + userID... User can filter his own results by dates and types which is why i need flexible and reliable solution thanks...

• C# dealing with invalid user input

  - by Zka

  Have a simple console app where user is asked for several values to input. Input is read via console.readline(). Ex Name: Fred //string Lastname: Ashcloud //string Age: 28 //int I would like to make sure that int and double types are entered and if the user enters garbage, lets him repeat the procedure. Example, if the user enters "28 years old" where age expects int the app will crash. What is the best way to check for these inputs? Right now I can only think of: while (!Int32.TryParse(text, out number)) { Console.WriteLine("Error write only numbers"); text = Console.ReadLine(); } Is there any other way to do this? try catch statements if one wants to give a more detailed feedback to the user? How in that case?

• Protocol buffer deserialization and a dynamically loaded DLL in Compact Framework

  - by cloudraven

  I saw a question related to this on the full framework here. Since it seems to have stayed unresolved for quite a while and this is for the compact framework, I though it would be better to create a new question for it. I want to deserialize types for which I am loading assemblies dynamically (with Assembly.LoadFrom) and I am getting a "Unable to identify known-type for ProtoIncludeAttribute" error. In the related question I mentioned, it was hinted that hooking AppDomain.AssemblyResolve event would help solving the problem. It makes sense for the full framework, but that event is not available in the CF. I wonder if there is a way to do this with CF. The structures I am using look a lot like this and all the classes required for deserialization are loaded from the same Assembly. If the assembly is referenced instead of dynamically loaded it works fine, but fails if done dynamically.

• Using unmanaged code, how can I find a type that has a given custom attribute assigned to it?

  - by Andrew

  I had thought I could enumerate the types using IMetaDataImport.EnumTypeDefs and for each of the tokens returned, call IMetaDataImport.EnumCustomAttributes. This works, in so much as I get an array of mdCustomAttribute tokens. Using these tokens I can get a metadata token representing the Type of the returned custom attribute, by calling IMetaDataImport.GetCustomAttributeProps. Comparing my results against ILDASM, I can see that this matches the "CustomAttribute Type" that ILDASM reports. However, I cannot work out how to determine the "CustomAttributeName" that ILDASM reports. This is what I really want! While I would be interested in knowing how to get the CustomAttributeName, I would settle for an alternate approach to solving the problem.

• Jquery/Javascript gmail style stuff for message inbox, such as select all message using checkbox etc

  - by Psychonetics

  I am enjoying the fact that I'm here building a private message inbox for my website after building a full user signup/login and activation system when a few months ago I thought I wouldn't have enough patience to learn this stuff. Anyway to my question. I am currently building the private message inbox for my users and wondering if there are any jquery/javascript stuff I can use to make my inbox more like the gmail inbox. E.G. Gmail allows you to select all read messages or unread or starred or unstarred or none of the messages using a checkbox. I would like to add this kind of feature to my website and I'm sure the easiest way to achieve this would be using a jquery/javascript script. I would appreciate if someone could provide some links or info to where I can find several of these types of scripts to use with my inbox page. Thanks EDIT: Would also like to note that I would like the checkbox to be in a dropdown just like gmails.

• Grails: Querying Associations causes groovy.lang.MissingMethodException

  - by Paul

  Hi, I've got an issue with Grails where I have a test app with: class Artist { static constraints = { name() } static hasMany = [albums:Album] String name } class Album { static constraints = { name() } static hasMany = [ tracks : Track ] static belongsTo = [artist: Artist] String name } class Track { static constraints = { name() lyrics(nullable: true) } Lyrics lyrics static belongsTo = [album: Album] String name } The following query (and a more advanced, nested association query) works in the Grails Console but fails with a groovy.lang.MissingMethodException when running the app with 'run-app': def albumCriteria = tunehub.Album.createCriteria() def albumResults = albumCriteria.list { like("name", receivedAlbum) artist { like("name", receivedArtist) } // Fails here maxResults(1) } Stacktrace: groovy.lang.MissingMethodException: No signature of method: java.lang.String.call() is applicable for argument types: (tunehub.LyricsService$_getLyrics_closure1_closure2) values: [tunehub.LyricsService$_getLyrics_closure1_closure2@604106] Possible solutions: wait(), any(), wait(long), each(groovy.lang.Closure), any(groovy.lang.Closure), trim() at tunehub.LyricsService$_getLyrics_closure1.doCall(LyricsService.groovy:61) at tunehub.LyricsService$_getLyrics_closure1.doCall(LyricsService.groovy) (...truncated...)

• document.getElementById in toString

  - by KooiInc

  edit Found my answers here. Bottom line: toString/valueOf can only return primitive types. So here the lack of native getters in javascript shows, I suppose. I would like to use the following simple function in an elementwrapper: function ElGetter(id){ var id = id; return { set: function(nwid){id = nwid;}, toString: function(){return document.getElementById(id);}, valueOf: function(){return document.getElementById(id);} }; } var myEl = ElGetter('myId'); console.log(myEl.innerHTML); //=> undefined But I can't get it to work. Is it a DOM/javascript restriction or am I missing something? Normally it works, as in: function Tester(){ var x = 1; return { toString: function(){return x}, valueOf: function(){return x} } } var myTest = Tester(); console.log(myTest); //=> 1

• Approaches for Error Code/Message Management in .NET

  - by WayneC

  Looking for suggestions/best practices on managing error codes and messages in a multi-tiered applications. Specifically things like: Where should error codes be defined? Enum? Class? How are error messages or further details associated with the error codes? resource files? attributes on enum values, etc.? If you have a multi-tier application consisting of DAL, BLL, UI, and Common projects for example, should there be a single giant list of codes for all tiers, or are the codes extensible by project/tier? Update: Important to mention that I can't rely solely on Exceptions and custom Exception types for error reporting, as some clients for this application will be via web services (SOAP & REST) Any suggestions welcome!

• Calling unmanaged c++ code in C# Mixed with STL

  - by Turtle

  Hey, I want to call unmanaged c++ code in C# The function interface is like following(I simplified it to make it easy to understand) Face genMesh(int param1, int param2); Face is a struct defined as: struct Face{ vector<float> nodes; vector<int> indexs; } I googled and read the MSDN docs found ways to call simple c/c++ unmanged code in C#, also know how to hand the struct as return value. And My question is how to handle "vector". I did not find rules about mapping between vector and some types in C# Thanks!

• WCF: generic list serialized to array

  - by OpticalDelusion

  So I am working with WCF and my services return types that contain generic lists. WCF is currently converting these to arrays over the wire. Is there a way I configure WCF to convert them back to lists afterwards? I know there is a way by clicking advanced when you add a service reference but I am looking for a solution in configuration files or something similar. [DataContract(IsReference = true)] public class SampleObject { [DataMember] public long ID { get; private set; } [DataMember] public ICollection<AnotherObject> Objects { get; set; } } It is very odd, also, because one service returns it as a list and the other as an array and I am pretty sure they are configured identically.

• Django Asynchronous Processing

  - by freyrs

  Hello all, I have a bunch of Django requests which executes some mathematical computations ( written in C and executed via a Cython module ) which may take an indeterminate amount ( on the order of 1 second ) of time to execute. Also the requests don't need to access the database. Right now everything is synchronous ( using Gunicorn with sync worker types ) but I'd like to make this asynchronous and nonblocking. I am very new to asynchronous Django, and so my question is what is the best stack for doing this. Is this sort of process something a task queue is well suited for? Would anyone recommend Tornado + Celery + RabbitMQ, or perhaps something else? Thanks in advance!
