  • Building Visual studio like application, need inputs..

    - by akjoshi
    Hi, I am working on a Visual studio like application i.e. hava a tolbox, an editor and property grid similar to VS. ser can drag and drop the controls(custom and third party) to the editor window and perform operations like resize, move, align, group etc.; Properties of that control needs to be displayed in property grid and user can update them from there. As per my current understanding I will have to extend the Canvas to create my own editor and and Interface for controls which it supports; Each supported control will have to implemnt this interface so that it can be placed in our editor. Something similar to this - http://www.codeproject.com/KB/WPF/WPFDiagramDesigner_Part4.aspx Looking forward for any kind of help, comment or links.

  • .Net SvcUtil: attributes must be optional

    - by Michel van Engelen
    Hi, I'm trying to generate C# code classes with SvcUtil.exe instead of Xsd.exe. The latter is giving me some problems. Command line: SvcUtil.exe myschema.xsd /dconly /ser:XmlSerializer Several SvcUtil problems are described and solved here: http://blog.shutupandcode.net/?p=761 One problem I can't solve is this one: Error: Type 'DatafieldDescription' in namespace '' cannot be imported. Attributes must be optional and from namespace 'http://schemas.microsoft.com/2003/10/Seri alization/'. Either change the schema so that the types can map to data contract types or use ImportXmlType or use a different serializer. ' I changed <xs:attribute name="Order" use="required"> to <xs:attribute name="Order" use="optional"> and <xs:attribute name="Order"> But the error remains. Is it possible to use attributes, or do I have to delete them all (in that case, this excercition is over)?

  • Copying part of a string in C

    - by wolfPack88
    This seems like it should be really simple, but for some reason, I'm not getting it to work. I have a string called seq, which looks like this: ala ile val I want to take the first 3 characters and copy them into a different string. I use the command: memcpy(fileName, seq, 3 * sizeof(char)); That should make fileName = "ala", right? But for some reason, I get fileName = "ala9". I'm currently working around it by just saying fileName[4] = '\0', but was wondering why I'm getting that 9. Note: After changing seq to ala ile val ser and rerunning the same code, fileName becomes "alaK". Not 9 anymore, but still an erroneous character.

  • Grails: Property Null error

    - by richardhell
    I've a domain called Modulo with some properties and a Controller with a method that create a object from model and save it, when execute save the shell show this error: La propiedad [{0}] de la clase [{1}] no puede ser nulo But if i set the constraint nullable to true, the error show again. I think that i should not set this cosntraint. The model is linked to a mysql table with all properties except id allow null. I think I am not doing something wrong here. Any advice?? Domain: Modulo class Modulo { String nombre String icon String url //static constraint = { // url(nullable:true) //} } Controller: Example class ExampleController { def index = { def modulo = new Modulo( nombre:'xxx', icon:'xxx' ) if (modulo.save()){ println 'ok' }else{ modulo.errors.allErrors.each { println it.defaultMessage} } } } Thanks.

  • How can I determine if a file I want to read from actually exists?

    - by Imray
    I'm learning Java, and I'm trying to write a program that can read from a .ser file, which I've already created with a writeTo method. I want to know a given file exists in the system before I tell the program to read from it. My code looks like this: public boolean readFromSerializedFile(String fileName){ FileInputStream fileInStream = null; ObjectInputStream objectInStream = null; try{ fileInStream = new FileInputStream(fileName); objectInStream = new ObjectInputStream(fileInStream); Is there a simple way I can determine if the file with the name of the parameter exists in the root directory (or wherever else specified)?

  • file to map/reduce program

    - by vana
    Hi , I am working on extracting Parts Of speech (POS) using xml documents and I have a englishPCFG.ser.gz file which is used in extracting POS on xml files. I cannot send this .gz file as input in HDFS directory, but my program uses it for parsing xml files. The file is in my local directory. I am getting "File Not Found" error when I run my mapreduce program. How can i make it available to mapper? I tried placing the file in HDFS where my xml files are present. I also tried adding it in .jar along with class files but not luck. I tried to change the hdfs-default.xml with entry to local directory, still doesnt work. Please let me know how to make mapper read this file? Thank you,

  • Mejores prácticas de Recursos Humanos: Cross Company Mentoring

    - by Fabian Gradolph
    Una de las cosas positivas de trabajar en una gran organización como Oracle es la posibilidad de participar en iniciativas de gran alcance que normalmente no están disponibles en muchas empresas. Ayer se presentó, junto con American Express y CocaCola, la tercera edición del programa Cross Company Mentoring, una iniciativa en la que las tres empresas colaboran facilitando mentores (profesionales experimentados) para promover el desarrollo profesional de individuos de talento en las tres empresas. La originalidad del programa estriba en que los mentores colaboran con el desarrollo de los profesionales de las otras empresas participantes y no sólo con los propios. La presentación inicial fue realizada por Alfredo García-Valverde, presidente de American Express en España. Posteriormente, Julia B. López, de American Express, y Rosa María Arias, de Oracle (en ese orden en la foto), han detallado en qué consiste la iniciativa, además de hacer balance de la edición anterior. Aunque este programa -complementario de los que ya funcionan en las tres empresas- está disponible para hombres y mujeres, hay que destacar que buena parte de su razón de ser está en potenciar el papel de mujeres profesionales de talento en las compañías. En términos generales, todas las grandes organizaciones se encuentran con un problema similar en el desarrollo del talento femenino. Independientemente del número de mujeres que formen parte de la plantilla de la empresa, lo cierto es que su número decrece de forma drástica cuando hablamos de los puestos directivos. La ruptura de ese "techo de cristal" es una prioridad para las empresas, tanto por motivos de simple justicia social, como por aprovechar al máximo todo el potencial del talento que ya existe dentro de las organizaciones, evitando que el talento femenino se "pierda" por no poder facilitar las oportunidades adecuadas para su desarrollo. La iniciativa de Cross Company Mentoring tiene unos objetivos bien definidos. En primer lugar, desarrollar el talento con un método innovador que permite conocer las mejores prácticas en otras empresas y aprovechar el talento externo. Adicionalmente, como ha señalado Julia López, es un método que nos fuerza a salir de la zona de confort, de las prácticas tradicionalmente aceptadas dentro de cada organización y que difícilmente se ponen en cuestión. El segundo objetivo es que el Mentee, el máximo beneficiario del programa, aprenda de la experiencia de profesionales de gran trayectoria para desarrollar sus propias soluciones en los retos que le plantee su carrera profesional. El programa que se ha presentado ahora, la tercera edición, arrancará en el próximo mes y estará vigente hasta finales de año. Seguro que tendrá tanto éxito como en las dos ediciones anteriores.

  • Why is my CPU being used while doing nothing?

    - by Jop
    I have installed Ubuntu GNOME in BIOS mode on my MacBook (BIOS mode so that the proprietary NVIDIA drivers work. I need them for gaming.). For some reason, a lot of CPU is being used while not really doing anything. It swings between 20-30% on both cores, usually. But when I look at the list of processes and sort by CPU usage, I do not see anything special. No processes intensively doing anything. How can I fix this? EDIT: Output of top command. jop@jop-MacBook:~$ top top - 17:08:02 up 41 min, 2 users, load average: 0,51, 0,69, 0,95 Tasks: 202 total, 2 running, 200 sleeping, 0 stopped, 0 zombie %Cpu(s): 11,9 us, 5,8 sy, 0,0 ni, 80,3 id, 0,5 wa, 0,0 hi, 1,5 si, 0,0 st KiB Mem: 7908316 total, 2919940 used, 4988376 free, 153248 buffers KiB Swap: 3906244 total, 0 used, 3906244 free, 1326544 cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 3785 root 20 0 195m 82m 26m S 22,9 1,1 2:43.77 Xorg 4429 jop 20 0 1543m 150m 60m S 7,3 1,9 1:26.26 compiz 4198 jop 20 0 633m 21m 11m S 1,7 0,3 0:04.96 unity-panel-ser 7425 jop 20 0 564m 18m 12m S 1,7 0,2 0:00.84 gnome-terminal 7019 jop 20 0 806m 89m 46m S 1,0 1,2 0:10.01 chrome 7323 jop 20 0 966m 93m 23m S 1,0 1,2 0:06.85 chrome 6742 root 20 0 0 0 0 S 0,7 0,0 0:00.43 kworker/0:3 3 root 20 0 0 0 0 S 0,3 0,0 0:06.01 ksoftirqd/0 7008 root 20 0 0 0 0 S 0,3 0,0 0:00.27 kworker/1:3 7302 jop 20 0 972m 96m 28m S 0,3 1,2 0:06.32 chrome 7310 jop 20 0 382m 63m 39m S 0,3 0,8 0:00.34 chrome 7498 jop 20 0 24840 1600 1120 R 0,3 0,0 0:00.22 top 1 root 20 0 27176 2944 1412 S 0,0 0,0 0:01.58 init 2 root 20 0 0 0 0 S 0,0 0,0 0:00.00 kthreadd 5 root 0 -20 0 0 0 S 0,0 0,0 0:00.00 kworker/0:0H 6 root 20 0 0 0 0 S 0,0 0,0 0:00.00 kworker/u4:0 7 root rt 0 0 0 0 S 0,0 0,0 0:02.04 migration/0 Even when xorg isn't so busy like when I copied, CPU usage is higher then what the processes use.

  • OpenAM throwing 302 0 behind haproxy, nginx

    - by Travis
    I'm having some issues with my deployment and was wondering if you can help. My set up is as follows: 2 OpenAM servers are set up behind a load balancer (HAproxy). The load balancer is set up behind two reverse proxies (nginx). The two reverse proxies are ser up behind another load balancer (haproxy). So a request will go through Haproxy nginx Haproxy openam I can access the OpenAM web console through the reverse proxies without a problem. Everything works fine at this level. However when I access openam through the load balancer in front of the reverse proxies Openam throws a 302 error. The funny thing is however I can access the host/openam/UI/Login and login successfully. I even get the cookie and have access to my apps that are set up. However immediately after the login OpenAM throws a 302 redirect. I'm puzzled and cannot figure out what is going wrong. Does anyone have any idea? My config files are below: nginx config : server { listen 443; server_name oamlb1; location / { proxy_pass http://oamlb1.mydomain.com:8080; proxy_set_header X-Real-IP $remote_addr; } location /openam { proxy_pass http://oamlb1.mydomain.com:8080; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host oamlb1.mydomain.com:8080; } } haproxy config : (This file is for the servers. The file for the reverse proxies is idenical except it points to the reverse proxies) listen http_proxy :8090 mode http balance roundrobin option httpclose option forwardfor server webA oamserver1.mydomain.com:18080 option forwardfor Thanks

  • Replace text with spaces in MySQL

    - by javipas
    I'm trying to do a global replace of search in my database, which has a lot of articles with a double carriage return because of this code: <p> </p> I'd like to replace this in my WordPress blog so instead of that appears... nothing, and so I can delete the CR. I've tried this on my database UPDATE wp_posts set post_content = replace (post_content,'<p> </p>',''); but didn't work. Why? Do I have to add special thinks to consider the space between the <p>and the</p>? Mmm. Good points, both Jon Angliss and Wim. Jon, as you could have guessed, the database shows no entries with that text string. So there's something going on inside the post_content field. Wim, the famous   was replaced previously, but there are still hundreds of posts that for some reason have something different between the p and the /p tags. I've done a search of one of the posts with this error: mysql> select * from wp_posts where post_title like '%3DVisionLive%'; And looking in the wp_content field, this is a little piece of the post: Phil Eisler, responsable de la divisi?n 3D Vision.?</p> <p>?</p> <p>Este portal ser? por tanto No spanish tilde (accent) shown on the terminal, and instead of an space there's a quotation mark between the p and the /p tags. I've tried to replace <p>?</p>, but again, no results. There's some character (or several) there, but I don't know how to discover that. Maybe it's the character set of my terminal, but I've accessed the database from phpmyadmin and in that case there's a space character between the p and the /p. Weird.

  • Programação paralela no .NET Framework 4 – Parte II

    - by anobre
    Olá pessoal, tudo bem? Este post é uma continuação da série iniciada neste outro post, sobre programação paralela. Meu objetivo hoje é apresentar o PLINQ, algo que poderá ser utilizado imediatamente nos projetos de vocês. Parallel LINQ (PLINQ) PLINQ nada mais é que uma implementação de programação paralela ao nosso famoso LINQ, através de métodos de extensão. O LINQ foi lançado com a versão 3.0 na plataforma .NET, apresentando uma maneira muito mais fácil e segura de manipular coleções IEnumerable ou IEnumerable<T>. O que veremos hoje é a “alteração” do LINQ to Objects, que é direcionado a coleções de objetos em memória. A principal diferença entre o LINQ to Objects “normal” e o paralelo é que na segunda opção o processamento é realizado tentando utilizar todos os recursos disponíveis para tal, obtendo uma melhora significante de performance. CUIDADO: Nem todas as operações ficam mais rápidas utilizando recursos de paralelismo. Não deixe de ler a seção “Performance” abaixo. ParallelEnumerable Tudo que a gente precisa para este post está organizado na classe ParallelEnumerable. Esta classe contém os métodos que iremos utilizar neste post, e muito mais: AsParallel AsSequential AsOrdered AsUnordered WithCancellation WithDegreeOfParallelism WithMergeOptions WithExecutionMode ForAll … O exemplo mais básico de como executar um código PLINQ é utilizando o métodos AsParallel, como o exemplo: var source = Enumerable.Range(1, 10000); var evenNums = from num in source.AsParallel() where Compute(num) > 0 select num; Algo tão interessante quanto esta facilidade é que o PLINQ não executa sempre de forma paralela. Dependendo da situação e da análise de alguns itens no cenário de execução, talvez seja mais adequado executar o código de forma sequencial – e nativamente o próprio PLINQ faz esta escolha.  É possível forçar a execução para sempre utilizar o paralelismo, caso seja necessário. Utilize o método WithExecutionMode no seu código PLINQ. Um teste muito simples onde podemos visualizar a diferença é demonstrado abaixo: static void Main(string[] args) { IEnumerable<int> numbers = Enumerable.Range(1, 1000); IEnumerable<int> results = from n in numbers.AsParallel() where IsDivisibleByFive(n) select n; Stopwatch sw = Stopwatch.StartNew(); IList<int> resultsList = results.ToList(); Console.WriteLine("{0} itens", resultsList.Count()); sw.Stop(); Console.WriteLine("Tempo de execução: {0} ms", sw.ElapsedMilliseconds); Console.WriteLine("Fim..."); Console.ReadKey(true); } static bool IsDivisibleByFive(int i) { Thread.SpinWait(2000000); return i % 5 == 0; }   Basta remover o AsParallel da instrução LINQ que você terá uma noção prática da diferença de performance. 1. Instrução utilizando AsParallel   2. Instrução sem utilizar paralelismo Performance Apesar de todos os benefícios, não podemos utilizar PLINQ sem conhecer todos os seus detalhes. Lembre-se de fazer as perguntas básicas: Eu tenho trabalho suficiente que justifique utilizar paralelismo? Mesmo com o overhead do PLINQ, vamos ter algum benefício? Por este motivo, visite este link e conheça todos os aspectos, antes de utilizar os recursos disponíveis. Conclusão Utilizar recursos de paralelismo é ótimo, aumenta a performance, utiliza o investimento realizado em hardware – tudo isso sem custo de produtividade. Porém, não podemos usufruir de qualquer tipo de tecnologia sem conhece-la a fundo antes. Portanto, faça bom uso, mas não esqueça de manter o conhecimento a frente da empolgação. Abraços.

  • Desktop login fails, terminal works

    - by Tobias
    I have a freshly setup 12.04 LTS pc system (120 GB SSD, 1 TB HDD, 16 GiB RAM); since a few days, I can't login to the graphical desktop anymore: there is very short flashing shell window which disappears very quickly, and I'm confronted with the login screen again. I believe there is something about modprobe and vbox, but I can't read it fast enough ... I can login to a terminal (Ctrl+Alt+F1). It did not help to chown all contents of my home directory to me:my-group, like suggested here. This is what I could find in /var/log, grepping for the date and time (I inserted linebreaks after <my-hostname>; real time values preserved): auth.log: <date> 22:43:01 <my-hostname> lightdm: pam_succeed_if(lightdm:auth): requirement "user ingroup nopasswdlogin" not met by user "tobias" <date> 22:43:08 <my-hostname> lightdm: pam_unix(lightdm:session): session closed for user lightdm <date> 22:43:08 <my-hostname> lightdm: pam_unix(lightdm:session): session opened for user tobias by (uid=0) <date> 22:43:08 <my-hostname> lightdm: pam_ck_connector(lightdm:session): nox11 mode, ignoring PAM_TTY :0 <date> 22:43:08 <my-hostname> lightdm: pam_unix(lightdm:session): session closed for user tobias <date> 22:43:09 <my-hostname> lightdm: pam_unix(lightdm:session): session opened for user lightdm by (uid=0) <date> 22:43:09 <my-hostname> lightdm: pam_ck_connector(lightdm:session): nox11 mode, ignoring PAM_TTY :0 <date> 22:43:10 <my-hostname> lightdm: pam_succeed_if(lightdm:auth): requirement "user ingroup nopasswdlogin" not met by user "tobias" <date> 22:43:10 <my-hostname> dbus[756]: [system] Rejected send message, 2 matched rules; type="method_call", sender="1:43" (uid=104 pid=1639 comm="/usr/lib/indicator-datetime/indicator-datetime-ser") interface="org.freedesktop.DBus.Properties" member="GetAll" error name="(unset)" requested_reply="0" destination=":1.15" (uid=0 pid=1005 comm="/usr/sbin/console-kit-daemon --no-daemon ") kern.log: <date> 22:43:00 <my-hostname> kernel: [ 16.084525] eth0: no IPv6 routers present syslog: <date> 22:43:00 <my-hostname> kernel: [ 16.084525] eth0: no IPv6 routers present <date> 22:43:01 <my-hostname> ntpdate[1492]: adjust time server 91.189.94.4 offset -0.162831 sec <date> 22:43:08 <my-hostname> acpid: client 969[0:0] has disconnected <date> 22:43:08 <my-hostname> acpid: client connected from 1553[0:0] <date> 22:43:08 <my-hostname> acpid: 1 client rule loaded I have Virtualbox and Truecrypt installed, but I can't think of a reason why they might prevent a graphical login. I'm confused: What is this about requirement "user ingroup nopasswdlogin" not met? I do login using a password, and the password works ok when logging in to a terminal! Can I somehow read the error output, e.g. by delaying it, redirecting it to a file, or having the system prompt me for pressing a key? Has possibly any recent update caused my problem? Should I install the pending updates? How, btw, without access to the graphical UI? I have some working knowledge about the Linux shell, but I'm new to Ubuntu. Any help would be appreciated.

  • [EF + ORACLE] Updating and Deleting Entities

    - by JTorrecilla
    Prologue In previous chapters we have seen how to insert data through EF, with and without sequences. In this one, we are going to see how to Update and delete Data from the DB. Updating data The update of the Entity Data (properties) is a very common and easy action. Before of change any of the properties of the Entity, we can check the EntityState property, and we can see that is EntityState.Unchanged.   For making an update it is needed to get the Entity which will be modified. In the following example, I use the GetEmployeeByNumber to get a valid Entity: 1: EMPLEADOS emp=GetEmployeeByNumber(2); 2: emp.Name="a"; 3: emp.Phone="2"; 4: emp.Mail="aa"; After modifying the desired properties of the Entity, we are going to check again Entitystate property, which now has the EntityState.Modified value. To persist the changes to the DB is necessary to invoke the SaveChanges function of our context. 1: context.SaveChanges(); After modifying the desired properties of the Entity, we are going to check again Entitystate property, which now has the EntityState.Modified value. To persist the changes to the DB is necessary to invoke the SaveChanges function of our context. If we check again the EntityState property we will see that the value will be EntityState.Unchanged.   Deleting Data Another easy action is to delete an Entity.   The first step to delete an Entity from the DB is to select the entity: 1: CLIENTS selectedClient = GetClientByNumber(15); 2: context.CLIENTES.DeleteObject(clienteSeleccionado); Before invoking the DeleteObject function, we will check EntityStet which value must be EntityState.Unchanged. After deleting the object, the state will be changed to EntitySate.Deleted. To commit the action we have to invoke the SaveChanges function. Aftar that, the EntityState property will be EntityState.Detached. Cascade Entity Framework lets cascade updates and deletes, although I never see cascade updates. What is a cascade delete? A cascade delete is an action that allows to delete all the related object to the object we desire to delete. This option could be established in the DB manager, or it could be in the EF model designer. For example: With a given relation (1-N) between clients and requests. The common situation must be to let delete those clients whose have no requests. If we select the relation between both entities, and press the second mouse button, we can see the properties panel of the relation. The props are: This grid shows the relations indicating the Master table(Clients) and the end point (Cabecera or Requests) The property “End 1 OnDelete” indicates the action to do when a Entity from the Master will be deleted. There are two options: - None: No action will be done, it is said, if a Entity has details entities it could not be deleted. - Cascade: It will delete all related entities to the master Entity. If we enable the cascade delete in a relation, and we invoke the DeleteObject function of the set, we could observe that all the related object indicates a Entitystate.Deleted state. Like an update, insert or common delete, until we commit the changes with SaveChanges function, the data would not be commited. Si habilitamos el borrado en cascada de una relación, e invocamos a la función DeleteObject del conjunto, podremos observar que todas las entidades de Detalle (de la relación indicada) presentan el valor EntityState.Deleted en la propiedad EntityState. Del mismo modo que en el borrado, inserción o actualización, hasta que no se invoque al método SaveChanges, los cambios no van a ser confirmados en la Base de Datos. Finally In this chapter we have seen how to update a Entity, how to delete an Entity and how to implement Cascade Deleting through EF. In next chapters we will see how to query the DB data.

  • Parsing concatenated, non-delimited XML messages from TCP-stream using C#

    - by thaller
    I am trying to parse XML messages which are send to my C# application over TCP. Unfortunately, the protocol can not be changed and the XML messages are not delimited and no length prefix is used. Moreover the character encoding is not fixed but each message starts with an XML declaration <?xml>. The question is, how can i read one XML message at a time, using C#. Up to now, I tried to read the data from the TCP stream into a byte array and use it through a MemoryStream. The problem is, the buffer might contain more than one XML messages or the first message may be incomplete. In these cases, I get an exception when trying to parse it with XmlReader.Read or XmlDocument.Load, but unfortunately the XmlException does not really allow me to distinguish the problem (except parsing the localized error string). I tried using XmlReader.Read and count the number of Element and EndElement nodes. That way I know when I am finished reading the first, entire XML message. However, there are several problems. If the buffer does not yet contain the entire message, how can I distinguish the XmlException from an actually invalid, non-well-formed message? In other words, if an exception is thrown before reading the first root EndElement, how can I decide whether to abort the connection with error, or to collect more bytes from the TCP stream? If no exception occurs, the XmlReader is positioned at the start of the root EndElement. Casting the XmlReader to IXmlLineInfo gives me the current LineNumber and LinePosition, however it is not straight forward to get the byte position where the EndElement really ends. In order to do that, I would have to convert the byte array into a string (with the encoding specified in the XML declaration), seek to LineNumber,LinePosition and convert that back to the byte offset. I try to do that with StreamReader.ReadLine, but the stream reader gives no public access to the current byte position. All this seams very inelegant and non robust. I wonder if you have ideas for a better solution. Thank you. EDIT: I looked around and think that the situation is as follows (I might be wrong, corrections are welcome): I found no method so that the XmlReader can continue parsing a second XML message (at least not, if the second message has an XmlDeclaration). XmlTextReader.ResetState could do something similar, but for that I would have to assume the same encoding for all messages. Therefor I could not connect the XmlReader directly to the TcpStream. After closing the XmlReader, the buffer is not positioned at the readers last position. So it is not possible to close the reader and use a new one to continue with the next message. I guess the reason for this is, that the reader could not successfully seek on every possible input stream. When XmlReader throws an exception it can not be determined whether it happened because of an premature EOF or because of a non-wellformed XML. XmlReader.EOF is not set in case of an exception. As workaround I derived my own MemoryBuffer, which returns the very last byte as a single byte. This way I know that the XmlReader was really interested in the last byte and the following exception is likely due to a truncated message (this is kinda sloppy, in that it might not detect every non-wellformed message. However, after appending more bytes to the buffer, sooner or later the error will be detected. I could cast my XmlReader to the IXmlLineInfo interface, which gives access to the LineNumber and the LinePosition of the current node. So after reading the first message I remember these positions and use it to truncate the buffer. Here comes the really sloppy part, because I have to use the character encoding to get the byte position. I am sure you could find test cases for the code below where it breaks (e.g. internal elements with mixed encoding). But up to now it worked for all my tests. The parser class follows here -- may it be useful (I know, its very far from perfect...) class XmlParser { private byte[] buffer = new byte[0]; public int Length { get { return buffer.Length; } } // Append new binary data to the internal data buffer... public XmlParser Append(byte[] buffer2) { if (buffer2 != null && buffer2.Length > 0) { // I know, its not an efficient way to do this. // The EofMemoryStream should handle a List<byte[]> ... byte[] new_buffer = new byte[buffer.Length + buffer2.Length]; buffer.CopyTo(new_buffer, 0); buffer2.CopyTo(new_buffer, buffer.Length); buffer = new_buffer; } return this; } // MemoryStream which returns the last byte of the buffer individually, // so that we know that the buffering XmlReader really locked at the last // byte of the stream. // Moreover there is an EOF marker. private class EofMemoryStream: Stream { public bool EOF { get; private set; } private MemoryStream mem_; public override bool CanSeek { get { return false; } } public override bool CanWrite { get { return false; } } public override bool CanRead { get { return true; } } public override long Length { get { return mem_.Length; } } public override long Position { get { return mem_.Position; } set { throw new NotSupportedException(); } } public override void Flush() { mem_.Flush(); } public override long Seek(long offset, SeekOrigin origin) { throw new NotSupportedException(); } public override void SetLength(long value) { throw new NotSupportedException(); } public override void Write(byte[] buffer, int offset, int count) { throw new NotSupportedException(); } public override int Read(byte[] buffer, int offset, int count) { count = Math.Min(count, Math.Max(1, (int)(Length - Position - 1))); int nread = mem_.Read(buffer, offset, count); if (nread == 0) { EOF = true; } return nread; } public EofMemoryStream(byte[] buffer) { mem_ = new MemoryStream(buffer, false); EOF = false; } protected override void Dispose(bool disposing) { mem_.Dispose(); } } // Parses the first xml message from the stream. // If the first message is not yet complete, it returns null. // If the buffer contains non-wellformed xml, it ~should~ throw an exception. // After reading an xml message, it pops the data from the byte array. public Message deserialize() { if (buffer.Length == 0) { return null; } Message message = null; Encoding encoding = Message.default_encoding; //string xml = encoding.GetString(buffer); using (EofMemoryStream sbuffer = new EofMemoryStream (buffer)) { XmlDocument xmlDocument = null; XmlReaderSettings settings = new XmlReaderSettings(); int LineNumber = -1; int LinePosition = -1; bool truncate_buffer = false; using (XmlReader xmlReader = XmlReader.Create(sbuffer, settings)) { try { // Read to the first node (skipping over some element-types. // Don't use MoveToContent here, because it would skip the // XmlDeclaration too... while (xmlReader.Read() && (xmlReader.NodeType==XmlNodeType.Whitespace || xmlReader.NodeType==XmlNodeType.Comment)) { }; // Check for XML declaration. // If the message has an XmlDeclaration, extract the encoding. switch (xmlReader.NodeType) { case XmlNodeType.XmlDeclaration: while (xmlReader.MoveToNextAttribute()) { if (xmlReader.Name == "encoding") { encoding = Encoding.GetEncoding(xmlReader.Value); } } xmlReader.MoveToContent(); xmlReader.Read(); break; } // Move to the first element. xmlReader.MoveToContent(); // Read the entire document. xmlDocument = new XmlDocument(); xmlDocument.Load(xmlReader.ReadSubtree()); } catch (XmlException e) { // The parsing of the xml failed. If the XmlReader did // not yet look at the last byte, it is assumed that the // XML is invalid and the exception is re-thrown. if (sbuffer.EOF) { return null; } throw e; } { // Try to serialize an internal data structure using XmlSerializer. Type type = null; try { type = Type.GetType("my.namespace." + xmlDocument.DocumentElement.Name); } catch (Exception e) { // No specialized data container for this class found... } if (type == null) { message = new Message(); } else { // TODO: reuse the serializer... System.Xml.Serialization.XmlSerializer ser = new System.Xml.Serialization.XmlSerializer(type); message = (Message)ser.Deserialize(new XmlNodeReader(xmlDocument)); } message.doc = xmlDocument; } // At this point, the first XML message was sucessfully parsed. // Remember the lineposition of the current end element. IXmlLineInfo xmlLineInfo = xmlReader as IXmlLineInfo; if (xmlLineInfo != null && xmlLineInfo.HasLineInfo()) { LineNumber = xmlLineInfo.LineNumber; LinePosition = xmlLineInfo.LinePosition; } // Try to read the rest of the buffer. // If an exception is thrown, another xml message appears. // This way the xml parser could tell us that the message is finished here. // This would be prefered as truncating the buffer using the line info is sloppy. try { while (xmlReader.Read()) { } } catch { // There comes a second message. Needs workaround for trunkating. truncate_buffer = true; } } if (truncate_buffer) { if (LineNumber < 0) { throw new Exception("LineNumber not given. Cannot truncate xml buffer"); } // Convert the buffer to a string using the encoding found before // (or the default encoding). string s = encoding.GetString(buffer); // Seek to the line. int char_index = 0; while (--LineNumber > 0) { // Recognize \r , \n , \r\n as newlines... char_index = s.IndexOfAny(new char[] {'\r', '\n'}, char_index); // char_index should not be -1 because LineNumber>0, otherwise an RangeException is // thrown, which is appropriate. char_index++; if (s[char_index-1]=='\r' && s.Length>char_index && s[char_index]=='\n') { char_index++; } } char_index += LinePosition - 1; var rgx = new System.Text.RegularExpressions.Regex(xmlDocument.DocumentElement.Name + "[ \r\n\t]*\\>"); System.Text.RegularExpressions.Match match = rgx.Match(s, char_index); if (!match.Success || match.Index != char_index) { throw new Exception("could not find EndElement to truncate the xml buffer."); } char_index += match.Value.Length; // Convert the character offset back to the byte offset (for the given encoding). int line1_boffset = encoding.GetByteCount(s.Substring(0, char_index)); // remove the bytes from the buffer. buffer = buffer.Skip(line1_boffset).ToArray(); } else { buffer = new byte[0]; } } return message; } }
