  • 5 Ways to Parse XML in C#

    This tutorial illustrates five ways to parse XML in C#. To make the tutorial more user-friendly and easier to understand actual scripts can be tested and run in your Visual Web Developer environment. I ll emphasize ASP.NET web development applications implementations of parsing XML. With little modification of the scripts however they can also be tested in a console environment. You can download complete scripts illustrating each of these five ways at the end of the tutorial.... Comcast? Business Class - Official Site Learn About Comcast Small Business Services.

  • OWA, Outlook Anywhere, RPCPing Inconsistencies

    - by pk.
    I'm troubleshooting an Outlook Anywhere issue with a new Exchange 2010 server. The server in question, MS2010, is behind a SonicWALL NSA 2400 device and works wonderfully except for Outlook Anywhere. Outlook Anywhere works internally and I've verified (through Ctrl-Right Click --> Connection Status) that I'm able to connect to MS2010 over HTTPS. When trying to connect to the server using HTTPS from outside the firewall, I'm unable to do so. A Wireshark trace shows 30 or so successful HTTPS packet transmissions, and then it fails with 3 straight transmissions to a destination port of 135. I have no idea why my computer is attempting to access anything on port 135 since I've setup my profile to use HTTPS on both slow and fast connections. I'm 99% certain that the firewall is configured correctly. I run Outlook Web Access (also HTTPS) on the same server and there are no issues with access. EDIT: My Autodiscover settings are correct (as far as I can tell). My server passes the Outlook Anywhere and Autodiscover tests at https://www.testexchangeconnectivity.com/. I've been using the RPCPing utility to troubleshoot and have come across the following results: Internally- >rpcping -t ncacn_http -s mail.mydomain.com -o RpcProxy=mail.mydomain.com -P "pk,mydomain,*" -I "pk,mydomain,*" -H 1 -u 10 -a connect -F 3 -v 3 -E -R none RPCPing v2.12.

  • How to convert many-to-one XML data to DataSet?

    - by TruMan1
    I have an XML document that has a collection of objects. Each object has a key/value pair of label and value. I am trying to convert this into a DataSet, but when I do ds.ReadXml(xmlFile), then it creates two columns: label and value. What I would like is to have a column for each "label" and the value to be part of the row. here is my sample of the XML: <responses> <response> <properties id="1" Form="Account Request" Date="Tuesday, March 16, 2010 5:04:26 PM" Confirmation="True" /> <fields> <field> <label>Name</label> <value>John</value> </field> <field> <label>Email</label> <value>[email protected]</value> </field> <field> <label>Website</label> <value>http://domain1.com</value> </field> <field> <label>Phone</label> <value>999-999-9999</value> </field> <field> <label>Place of Birth</label> <value>Earth</value> </field> <field> <label>Misc</label> <value>Misc</value> </field> <field> <label>Comments</label> <value /> </field> <field> <label>Agree to Terms?</label> <value>True</value> </field> </fields> </response> <response> <properties id="2" Form="Account Request" Date="Tuesday, March 17, 2010 5:04:26 PM" Confirmation="True" /> <fields> <field> <label>Name</label> <value>John2</value> </field> <field> <label>Email</label> <value>[email protected]</value> </field> <field> <label>Website</label> <value>http://domain2.com</value> </field> <field> <label>Phone</label> <value>999-999-9999</value> </field> <field> <label>Place of Birth</label> <value>Earth</value> </field> <field> <label>Misc</label> <value>Misc</value> </field> <field> <label>Comments</label> <value /> </field> <field> <label>Agree to Terms?</label> <value>True</value> </field> </fields> </response> <response> <properties id="3" Form="Account Request" Date="Tuesday, March 18, 2010 5:04:26 PM" Confirmation="True" /> <fields> <field> <label>Name</label> <value>John3</value> </field> <field> <label>Email</label> <value>[email protected]</value> </field> <field> <label>Website</label> <value>http://domain3.com</value> </field> <field> <label>Phone</label> <value>999-999-9999</value> </field> <field> <label>Place of Birth</label> <value>Earth</value> </field> <field> <label>Misc</label> <value>Misc</value> </field> <field> <label>Comments</label> <value /> </field> <field> <label>Agree to Terms?</label> <value>True</value> </field> </fields> </response> <response> <properties id="4" Form="Account Request" Date="Tuesday, March 19, 2010 5:04:26 PM" Confirmation="True" /> <fields> <field> <label>Name</label> <value>John</value> </field> <field> <label>Email</label> <value>[email protected]</value> </field> <field> <label>Website</label> <value>http://domain4.com</value> </field> <field> <label>Phone</label> <value>999-999-9999</value> </field> <field> <label>Place of Birth</label> <value>Earth</value> </field> <field> <label>Misc</label> <value>Misc</value> </field> <field> <label>Comments</label> <value /> </field> <field> <label>Agree to Terms?</label> <value>True</value> </field> </fields> </response> </responses> How would I convert this to a DataSet so that I can load it into a gridview with the columns: Name, Email, Website, Phone, Place of Birth, Misc, Comments, and Agree to Terms? Then row 1 would be: John, [email protected], http://domain1.com, 999-999-9999, Earth, Misc, , True How can I do this with the XML provided?

  • Design Decision - Scaling out web based application's architecture

    - by Vadi
    This question is about design decision. I am currently working on a web project that will have 40K users to start with and in couple of month expected to grow 50M users (not concurrent users though). I would like to have a architecture that can be scaled out easily without much effort. In order to explain, I would like to use a trivial scenario. Lets say, User entities and services such as CreateUser, AuthenticateUser etc., are a simple method calls for the Page Controllers. But once the traffic increases, for example, authenticating user (or such services related to user entities) has to be moved out to a different internal server to spread the load. But at the same time using RPC calls over the network when the user count is 40K would become overkill. My proposal was to use IPC initially and when we need to scale out we can interally switch to TCP based RPC calls so that it can easily scale out. For example, I am referring to System.IO.Pipes.NamedPipeStreamServer to start with and move on to a TcpListener later on. If we have proper design that can encapsulate above said approach, it would easy for us to scale out services into multiple network servers but at the same time avoid network calls when the user count is small. Is this is a best approach? Any suggestions would be great .. Note: The database scaling is definetly the second phase optimization so we have already made architectural design in place to easily partition data when traffic increases. The primary bottleneck would be application servers over the time period.

  • Is there a good way of automatically generating javascript client code from server side python

    - by tat.wright
    I basically want to be able to: Write a few functions in python (with the minimum amount of extra meta data) Turn these functions into a web service (with the minimum of effort / boiler plate) Automatically generate some javascript functions / objects for rpc (this should prevent me from doing as many stupid things as possible like mistyping method names, forgetting the names of methods, passing the wrong number of arguments) Example python: def hello_world(): return "Hello world" javascript: ... <!-- This file is automatically generated (either dynamically or statically) --> <script src="http://myurl.com/webservice/client_side_javascript"> </script> ... <script> $('#button').click(function () { hello_world(function (data){ $('#label').text(data))) } </script> A bit of research has shown me some approaches that come close to this: Automatic generation of json-rpc services from functions with a little boiler plate code in python and then using jquery and json to do the calls (still easy to make mistakes with method names - still need to be aware of urls when calling, very irritating to write these calls yourself in the firebug shell) Using a library like soaplib to generate wsdl from python (by adding copious type information). And then somehow convert this into javascript (not sure if there is even a library to do this) But are there any approaches closer to what I want?

  • WebService Stubs WSDL Axis2

    - by tt0686
    Good afternoon in my timezone. I have a wsdl file with the following snippet of code: <schema targetNamespace="http://util.cgd.pt" xmlns="http://www.w3.org/2001/XMLSchema"> <import namespace="http://schemas.xmlsoap.org/soap/encoding/" /> <complexType name="Attribute"> <sequence> <element name="fieldType" nillable="true" type="xsd:string" /> <element name="dataType" nillable="true" type="xsd:string" /> <element name="name" nillable="true" type="xsd:string" /> <element name="value" nillable="true" type="xsd:string" /> </sequence> </complexType> <complexType name="ArrayOffAttribute"> <complexContent> <restriction base="soapenc:Array"> <attribute ref="soapenc:arrayType" wsdl:arrayType="tns3:Attribute[]" /> </restriction> </complexContent> </complexType> When i use jax-rpc or Axis1 to generate the stubs the type Attribute is generated, but when i use Axis2 the type Attribute is not generated and a new type is created ArrayOffAttribute, this new type extends the axis2.databinding.types.soapencoding.Array and permits to add elements through the array.addObject(object), my question is, i am migrating one Java EE application from webservices using jax-rpc to start using Axis2, and the methods are using the Attribute type to fullfill attributes fields, now in Axis2 and do not have attribute type , what should i use in the ArrayOffAttribute.addObject(?) ? Could be something wrong with Axis2 ? i am stop here :( Thanks in advance Best regards

  • What's a good Java-based Master-Slave communication mechanism?

    - by plecong
    I'm creating a Java application that requires master-slave communication between JVMs, possibly residing on the same physical machine. There will be a "master" server running inside a JEE application server (i.e. JBoss) that will have "slave" clients connect to it and dynamically register itself for communication (that is the master will not know the IP addresses/ports of the slaves so cannot be configured in advance). The master server acts as a controller that will dole work out to the slaves and the slaves will periodically respond with notifications, so there would be bi-directional communication. I was originally thinking of RPC-based systems where each side would be a server, but it could get complicated, so I'd prefer a mechanism where there's an open socket and they talk back and forth. I'm looking for a communication mechanism that would be low-latency where the messages would be mostly primitive types, so no serious serialization is necessary. Here's what I've looked at: RMI JMS: Built-in to Java, the "slave" clients would connect to the existing ConnectionFactory in the application server. JAX-WS/RS: Both master and slave would be servers exposing an RPC interface for bi-directional communication. JGroups/Hazelcast: Use shared distributed data structures to facilitate communication. Memcached/MongoDB: Use these as "queues" to facilitate communication, though the clients would have to poll so there would be some latency. Thrift: This does seem to keep a persistent connection, but not sure how to integrate/embed a Thrift server into JBoss WebSocket/Raw Socket: This would work, but require a lot more custom code than I'd like. Is there any technology I'm missing? Edit: Also looked at: JMX: Have the client connect to JBoss' JMX server and receive JMX notifications for bidirectional comms.

  • Download dynaic file with GWT

    - by Maksim
    I have a GWT page where user enter data (start date, end date, etc.), then this data goes to the server via RPC call. On the server I want to generate Excel report with POI and let user save that file on their local machine. This is my test code to stream file back to the client but for some reason it does not know: public class ReportsServiceImpl extends RemoteServiceServlet implements ReportsService { public String myMethod(String s) { File f = new File("/excelTestFile.xls"); String filename = f.getName(); int length = 0; try { HttpServletResponse resp = getThreadLocalResponse(); ServletOutputStream op = resp.getOutputStream(); ServletContext context = getServletConfig().getServletContext(); resp.setContentType("application/octet-stream"); resp.setContentLength((int) f.length()); resp.setHeader("Content-Disposition", "attachment; filename*=\"utf-8''" + filename + ""); byte[] bbuf = new byte[1024]; DataInputStream in = new DataInputStream(new FileInputStream(f)); while ((in != null) && ((length = in.read(bbuf)) != -1)) { op.write(bbuf, 0, length); } in.close(); op.flush(); op.close(); } catch (Exception ex) { ex.printStackTrace(); } return "Server says: " + filename; } } I've red somewhere on internet that you can't do file stream with RPC and I have to use Servlet for that. Is there any example of how to use Servlet and how to call that servlet from ReportsServiceImpl

  • How to store a shmup level?

    - by pek
    I am developing a 2D shmup (i.e. Aero Fighters) and I was wondering what are the various ways to store a level. Assuming that enemies are defined in their own xml file, how would you define when an enemy spawns in the level? Would it be based on time? Updates? Distance? Currently I do this based on "level time" (the amount of time the level is running - pausing doesn't update the time). Here is an example (the serialization was done by XNA): <?xml version="1.0" encoding="utf-8"?> <XnaContent xmlns:level="pekalicious.xanor.XanorContentShared.content.level"> <Asset Type="level:Level"> <Enemies> <Enemy> <EnemyType>data/enemies/smallenemy</EnemyType> <SpawnTime>PT0S</SpawnTime> <NumberOfSpawns>60</NumberOfSpawns> <SpawnOffset>PT0.2S</SpawnOffset> </Enemy> <Enemy> <EnemyType>data/enemies/secondenemy</EnemyType> <SpawnTime>PT0S</SpawnTime> <NumberOfSpawns>10</NumberOfSpawns> <SpawnOffset>PT0.5S</SpawnOffset> </Enemy> <Enemy> <EnemyType>data/enemies/secondenemy</EnemyType> <SpawnTime>PT20S</SpawnTime> <NumberOfSpawns>10</NumberOfSpawns> <SpawnOffset>PT0.5S</SpawnOffset> </Enemy> <Enemy> <EnemyType>data/enemies/boss1</EnemyType> <SpawnTime>PT30S</SpawnTime> <NumberOfSpawns>1</NumberOfSpawns> <SpawnOffset>PT0S</SpawnOffset> </Enemy> </Enemies> </Asset> </XnaContent> Each Enemy element is basically a wave of specific enemy types. The type is defined in EnemyType while SpawnTime is the "level time" this wave should appear. NumberOfSpawns and SpawnOffset is the number of enemies that will show up and the time it takes between each spawn respectively. This could be a good idea or there could be better ones out there. I'm not sure. I would like to see some opinions and ideas. I have two problems with this: spawning an enemy correctly and creating a level editor. The level editor thing is an entirely different problem (which I will probably post in the future :P). As for spawning correctly, the problem lies in the fact that I have a variable update time and so I need to make sure I don't miss an enemy spawn because the spawn offset is too small, or because the update took a little more time. I kinda fixed it for the most part, but it seems to me that the problem is with how I store the level. So, any ideas? Comments? Thank you in advance.

  • Special characters from MySQL database (e.g. curly apostrophes) are mangling my XML

    - by Toph
    I have a MySQL database of newspaper articles. There's a volume table, an issue table, and an article table. I have a PHP file that generates a property list that is then pulled in and read by an iPhone app. The plist holds each article as a dictionary inside each issue, and each issue as a dictionary inside each volume. The plist doesn't actually hold the whole article -- just a title and URL. Some article titles contain special characters, like curly apostrophes. Looking at the generated XML plist, whenever it hits a special character, it unpredictably gobbles up a whole bunch of text, leaving the XML mangled and unreadable. (...in Chrome, anyway, and I'm guessing on the iPhone. Firefox actually handles it pretty well, showing a white ? in a black diamond in place of any special characters and not gobbling anything.) Example well-formed plist snippet: <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Rows</key> <array> <dict> <key>Title</key> <string>Vol. 133 (2003-2004)</string> <key>Children</key> <array> <dict> <key>Title</key> <string>No. 18 (Apr 2, 2004)</string> <key>Children</key> <array> <dict> <key>Title</key> <string>Basketball concludes historic season</string> <key>URL</key> <string>http://orient.bowdoin.edu/orient/article_iphone.php?date=2004-04-02&amp;section=1&amp;id=1</string> </dict> <!-- ... --> </array> </dict> </array> </dict> </array> </dict> </plist> Example of what happens when it hits a curly apostrophe: This is from Chrome. This time it ate 5,998 characters, by MS Word's count, skipping down to midway through the opening the title of a pizza story; if I reload it'll behave differently, eating some other amount. The proper title is: Singer-songwriter Farrell ’05 finds success beyond the bubble <dict> <key>Title</key> <string>Singer-songwriter Farrell ing>Students embrace free pizza, College objects to solicitation</string> <key>URL</key> <string>http://orient.bowdoin.edu/orient/article_iphone.php?date=2009-09-18&amp;section=1&amp;id=9</string> </dict> In MySQL that title is stored as (in binary): 53 69 6E 67 |65 72 2D 73 |6F 6E 67 77 |72 69 74 65 72 20 46 61 |72 72 65 6C |6C 20 C2 92 |30 35 20 66 69 6E 64 73 |20 73 75 63 |63 65 73 73 |20 62 65 79 6F 6E 64 20 |74 68 65 20 |62 75 62 62 |6C Any ideas how I can encode/decode things properly? If not, any idea how I can get around the problem some other way? I don't have a clue what I'm talking about, haha; let me know if there's any way I can help you help me. :) And many thanks!

  • Add rss xmlns namespace definition to a php simplexml document?

    - by talkingnews
    I'm trying to create an itunes-valid podcast feed using php5's simplexml: <?php $xml_string = <<<XML <?xml version="1.0" encoding="UTF-8"?> <channel> </channel> XML; $xml_generator = new SimpleXMLElement($xml_string); $tnsoundfile = $xml_generator->addChild('title', 'Main Title'); $tnsoundfile->addChild('itunes:author', "Author", ' '); $tnsoundfile->addChild('category', 'Audio Podcasts'); $tnsoundfile = $xml_generator->addChild('item'); $tnsoundfile->addChild('title', 'The track title'); $enclosure = $tnsoundfile->addChild('enclosure'); $enclosure->addAttribute('url', 'http://test.com'); $enclosure->addAttribute('length', 'filelength'); $enclosure->addAttribute('type', 'audio/mpeg'); $tnsoundfile->addChild('itunes:author', "Author", ' '); header("Content-Type: text/xml"); echo $xml_generator->asXML(); ?> It doesn't validate, because I've got to put the line: <rss xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd" version="2.0"> as per http://www.apple.com/itunes/podcasts/specs.html. So the output SHOULD be: <?xml version="1.0" encoding="UTF-8"?> <rss xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd" version="2.0"> <channel> etc. I've been over and over the manual and forums, just can't get it right. If I put, near the footer: header("Content-Type: text/xml"); echo '<rss xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd" version="2.0">'; echo $xml_generator->asXML(); ?> Then it sort of looks right in firefox and it doesn't complain about undefined namespaces anymore, but feedvalidator complains that line 1, column 77: XML parsing error: :1:77: xml declaration not at start of external entity [help] because the document now starts: <rss xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd" version="2.0"><?xml version="1.0" encoding="UTF-8"?> and not <?xml version="1.0" encoding="UTF-8"?><rss xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd" version="2.0"> Thank you in advance.

  • Validating against a Schema with JAXB

    - by fwgx
    I've been looking for solutions to this problem for far too long considering how easy it sounds so I've come for some help. I have an XML Schema which I have used with xjc to create my JAXB binding. This works fine when the XML is well formed. Unfortunately it also doesn't complain when the XML is not well formed. I cannot figure out how to do proper full validation against the schema when I try to unmarshall an XML file. I have managed to use a ValidationEventCollector to handle events, which works for XML parsing errors such as mismatched tags but doesn't raise any events when there is a tag that is required but is completely absent. From what I have seen validation can be done againsta schema, but you must know the path to the schema in order to pass it into the setSchema() method. The problem I have is that the path to the schema is stored in the XML header and I can't knwo at run time where the schema is going to be. Which is why it's stored in the XML file: <?xml version="1.0" encoding="utf-8"?> <DDSSettings xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="/a/big/long/path/to/a/schema/file/DDSSettings.xsd"> <Field1>1</Field1> <Field2>-1</Field2> ...etc Every example I see uses setValidating(true), which is now deprecated, so throws an exception. This is the Java code I have so far, which seems to only do XML validation, not schema validation: try { JAXBContext jc = new JAXBContext() { private final JAXBContext jaxbContext = JAXBContext.newInstance("blah"); @Override public Unmarshaller createUnmarshaller() throws JAXBException { Unmarshaller unmarshaller = jaxbContext.createUnmarshaller(); ValidationEventCollector vec = new ValidationEventCollector() { @Override public boolean handleEvent(ValidationEvent event) throws RuntimeException { ValidationEventLocator vel = event.getLocator(); if (event.getSeverity() == event.ERROR || event.getSeverity() == event.FATAL_ERROR) { String error = "XML Validation Exception: " + event.getMessage() + " at row: " + vel.getLineNumber() + " column: " + vel.getColumnNumber(); System.out.println(error); } m_unmarshallingOk = false; return false; } }; unmarshaller.setEventHandler(vec); return unmarshaller; } @Override public Marshaller createMarshaller() throws JAXBException { throw new UnsupportedOperationException("Not supported yet."); } @Override @SuppressWarnings("deprecation") public Validator createValidator() throws JAXBException { throw new UnsupportedOperationException("Not supported yet."); } }; Unmarshaller unmarshaller = jc.createUnmarshaller(); m_ddsSettings = (com.ultra.DDSSettings)unmarshaller.unmarshal(new File(xmlfileName)); } catch (UnmarshalException ex) { Logger.getLogger(UniversalDomainParticipant.class.getName()).log( Level.SEVERE, null, ex); } catch (JAXBException ex) { Logger.getLogger(UniversalDomainParticipant.class.getName()).log( Level.SEVERE, null, ex); } So what is the proper way to do this validation? I was expecting there to be a validate() method on the JAXB generated classes, but I guess that would be too simple for Java.

  • PHP Increasing write to page speed.

    - by Frederico
    I'm currently writing out xml and have done the following: header ("content-type: text/xml"); header ("content-length: ".strlen($xml)); $xml being the xml to be written out. I'm near about 1.8 megs of text (which I found via firebug), it seems as the writing is taking more time than the script to run.. is there a way to increase this write speed? Thank you in advance.

  • Flex 4: Getter getting before setter sets

    - by Steve
    I've created an AS class to use as a data model, shown here: package { import mx.controls.Alert; import mx.rpc.events.FaultEvent; import mx.rpc.events.ResultEvent; import mx.rpc.http.HTTPService; public class Model { private var xmlService:HTTPService; private var _xml:XML; private var xmlChanged:Boolean = false; public function Model() { } public function loadXML(url:String):void { xmlService = new HTTPService(); if (!url) xmlService.url = "DATAPOINTS.xml"; else xmlService.url = url; xmlService.resultFormat = "e4x"; xmlService.addEventListener(ResultEvent.RESULT, setXML); xmlService.addEventListener(FaultEvent.FAULT, faultXML); xmlService.send(); } private function setXML(event:ResultEvent):void { xmlChanged = true; this._xml = event.result as XML; } private function faultXML(event:FaultEvent):void { Alert.show("RAF data could not be loaded."); } public function get xml():XML { return _xml; } } } And in my main application, I'm initiating the app and calling the loadXML function to get the XML: <fx:Script> <![CDATA[ import mx.containers.Form; import mx.containers.FormItem; import mx.containers.VBox; import mx.controls.Alert; import mx.controls.Button; import mx.controls.Label; import mx.controls.Text; import mx.controls.TextInput; import spark.components.NavigatorContent; private function init():void { var model:Model = new Model(); model.loadXML(null); var xml:XML = model.xml; } ]]> </fx:Script> The trouble I'm having is that the getter function is running before loadXML has finished, so the XML varible in my main app comes up undefined in stack traces. How do I put a condition in here somewhere that tells the getter to wait until the loadXML() function has finished before running?

  • how to populate the tables within xmlDataDocument.DataSet

    - by alex
    Hi all: I am working on a C# application that involves using XML schema file as databases for message definitions and XML file as databases for message data. I was following the example I found:http://msdn.microsoft.com/en-us/library/system.xml.xmldatadocument.dataset%28v=VS.100%29.aspx I wrote my own xsd and XML file. I used the same approach in the example, read the xsd file and then load the xml file. But I don't have any "Rows" created for my DataTable. I used debugger to step through my codes. When I am get my DataTable use xmlDataDocument.DataSet.Tables["name of the table"], the Rows property of that tables is 0. Does anybody know what might cause the DataSet tables not get populated after I loaded the xmlDataDocument with XML file? Here is a fragment of XSD file: <?xml version="1.0" encoding="utf-8"?> <xs:schema id="test" targetNamespace="http://tempuri.org/test.xsd" elementFormDefault="qualified" xmlns="http://tempuri.org/test.xsd" xmlns:mstns="http://tempuri.org/test.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema" > <xs:element name="reboot_msg"> <xs:complexType> <xs:complexContent> <xs:extension base="header_s"> <xs:sequence> <xs:element name="que_name"> <xs:simpleType> <xs:restriction base="xs:string"> <xs:minLength value="4"/> <xs:maxLength value="8"/> </xs:restriction> </xs:simpleType> </xs:element> <xs:element name="priority" type="xs:unsignedShort"/> </xs:sequence> </xs:extension> </xs:complexContent> </xs:complexType> </xs:element> and here is a fragment of the XML file: <?xml version="1.0" standalone="yes"?> <test xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" > <reboot_msg> <message_length>16</message_length> <message_type>7</message_type> <message_sequence>0</message_sequence> <que_name>NONE</que_name> <priority>5</priority> </reboot_msg> It could be the XML and XSD file I created missed something. Please help. Thanks

  • Converting Encrypted Values

    - by Johnm
    Your database has been protecting sensitive data at rest using the cell-level encryption features of SQL Server for quite sometime. The employees in the auditing department have been inviting you to their after-work gatherings and buying you drinks. Thousands of customers implicitly include you in their prayers of thanks giving as their identities remain safe in your company's database. The cipher text resting snuggly in a column of the varbinary data type is great for security; but it can create some interesting challenges when interacting with other data types such as the XML data type. The XML data type is one that is often used as a message type for the Service Broker feature of SQL Server. It also can be an interesting data type to capture for auditing or integrating with external systems. The challenge that cipher text presents is that the need for decryption remains even after it has experienced its XML metamorphosis. Quite an interesting challenge nonetheless; but fear not. There is a solution. To simulate this scenario, we first will want to create a plain text value for us to encrypt. We will do this by creating a variable to store our plain text value: -- set plain text value DECLARE @PlainText NVARCHAR(255); SET @PlainText = 'This is plain text to encrypt'; The next step will be to create a variable that will store the cipher text that is generated from the encryption process. We will populate this variable by using a pre-defined symmetric key and certificate combination: -- encrypt plain text value DECLARE @CipherText VARBINARY(MAX); OPEN SYMMETRIC KEY SymKey     DECRYPTION BY CERTIFICATE SymCert     WITH PASSWORD='mypassword2010';     SET @CipherText = EncryptByKey                          (                            Key_GUID('SymKey'),                            @PlainText                           ); CLOSE ALL SYMMETRIC KEYS; The value of our newly generated cipher text is 0x006E12933CBFB0469F79ABCC79A583--. This will be important as we reference our cipher text later in this post. Our final step in preparing our scenario is to create a table variable to simulate the existence of a table that contains a column used to hold encrypted values. Once this table variable has been created, populate the table variable with the newly generated cipher text: -- capture value in table variable DECLARE @tbl TABLE (EncVal varbinary(MAX)); INSERT INTO @tbl (EncVal) VALUES (@CipherText); We are now ready to experience the challenge of capturing our encrypted column in an XML data type using the FOR XML clause: -- capture set in xml DECLARE @xml XML; SET @xml = (SELECT               EncVal             FROM @tbl AS MYTABLE             FOR XML AUTO, BINARY BASE64, ROOT('root')); If you add the SELECT @XML statement at the end of this portion of the code you will see the contents of the XML data in its raw format: <root>   <MYTABLE EncVal="AG4Skzy/sEafeavMeaWDBwEAAACE--" /> </root> Strangely, the value that is captured appears nothing like the value that was created through the encryption process. The result being that when this XML is converted into a readable data set the encrypted value will not be able to be decrypted, even with access to the symmetric key and certificate used to perform the decryption. An immediate thought might be to convert the varbinary data type to either a varchar or nvarchar before creating the XML data. This approach makes good sense. The code for this might look something like the following: -- capture set in xml DECLARE @xml XML; SET @xml = (SELECT              CONVERT(NVARCHAR(MAX),EncVal) AS EncVal             FROM @tbl AS MYTABLE             FOR XML AUTO, BINARY BASE64, ROOT('root')); However, this results in the following error: Msg 9420, Level 16, State 1, Line 26 XML parsing: line 1, character 37, illegal xml character A quick query that returns CONVERT(NVARCHAR(MAX),EncVal) reveals that the value that is causing the error looks like something off of a genuine Chinese menu. While this situation does present us with one of those spine-tingling, expletive-generating challenges, rest assured that this approach is on the right track. With the addition of the "style" argument to the CONVERT method, our solution is at hand. When dealing with converting varbinary data types we have three styles available to us: - The first is to not include the style parameter, or use the value of "0". As we see, this style will not work for us. - The second option is to use the value of "1" will keep our varbinary value including the "0x" prefix. In our case, the value will be 0x006E12933CBFB0469F79ABCC79A583-- - The third option is to use the value of "2" which will chop the "0x" prefix off of our varbinary value. In our case, the value will be 006E12933CBFB0469F79ABCC79A583-- Since we will want to convert this back to varbinary when reading this value from the XML data we will want the "0x" prefix, so we will want to change our code as follows: -- capture set in xml DECLARE @xml XML; SET @xml = (SELECT              CONVERT(NVARCHAR(MAX),EncVal,1) AS EncVal             FROM @tbl AS MYTABLE             FOR XML AUTO, BINARY BASE64, ROOT('root')); Once again, with the inclusion of the SELECT @XML statement at the end of this portion of the code you will see the contents of the XML data in its raw format: <root>   <MYTABLE EncVal="0x006E12933CBFB0469F79ABCC79A583--" /> </root> Nice! We are now cooking with gas. To continue our scenario, we will want to parse the XML data into a data set so that we can glean our freshly captured cipher text. Once we have our cipher text snagged we will capture it into a variable so that it can be used during decryption: -- read back xml DECLARE @hdoc INT; DECLARE @EncVal NVARCHAR(MAX); EXEC sp_xml_preparedocument @hDoc OUTPUT, @xml; SELECT @EncVal = EncVal FROM OPENXML (@hdoc, '/root/MYTABLE') WITH ([EncVal] VARBINARY(MAX) '@EncVal'); EXEC sp_xml_removedocument @hDoc; Finally, the decryption of our cipher text using the DECRYPTBYKEYAUTOCERT method and the certificate utilized to perform the encryption earlier in our exercise: SELECT     CONVERT(NVARCHAR(MAX),                     DecryptByKeyAutoCert                          (                            CERT_ID('AuditLogCert'),                            N'mypassword2010',                            @EncVal                           )                     ) EncVal; Ah yes, another hurdle presents itself! The decryption produced the value of NULL which in cryptography means that either you don't have permissions to decrypt the cipher text or something went wrong during the decryption process (ok, sometimes the value is actually NULL; but not in this case). As we see, the @EncVal variable is an nvarchar data type. The third parameter of the DECRYPTBYKEYAUTOCERT method requires a varbinary value. Therefore we will need to utilize our handy-dandy CONVERT method: SELECT     CONVERT(NVARCHAR(MAX),                     DecryptByKeyAutoCert                          (                             CERT_ID('AuditLogCert'),                             N'mypassword2010',                             CONVERT(VARBINARY(MAX),@EncVal)                           )                     ) EncVal; Oh, almost. The result remains NULL despite our conversion to the varbinary data type. This is due to the creation of an varbinary value that does not reflect the actual value of our @EncVal variable; but rather a varbinary conversion of the variable itself. In this case, something like 0x3000780030003000360045003--. Considering the "style" parameter got us past XML challenge, we will want to consider its power for this challenge as well. Knowing that the value of "1" will provide us with the actual value including the "0x", we will opt to utilize that value in this case: SELECT     CONVERT(NVARCHAR(MAX),                     DecryptByKeyAutoCert                          (                            CERT_ID('SymCert'),                            N'mypassword2010',                            CONVERT(VARBINARY(MAX),@EncVal,1)                           )                     ) EncVal; Bingo, we have success! We have discovered what happens with varbinary data when captured as XML data. We have figured out how to make this data useful post-XML-ification. Best of all we now have a choice in after-work parties now that our very happy client who depends on our XML based interface invites us for dinner in celebration. All thanks to the effective use of the style parameter.

  • Where to place ClientAccessPolicy.xml for Local WCF Service?

    - by cam
    I'm trying to create a basic WCF Service and Silverlight client. I've followed the following tutorial: http://channel9.msdn.com/shows/Endpoint/Endpoint-Screencasts-Creating-Your-First-WCF-Client/ Since Silverlight 4 was incompatible with the WSHttpBinding, I changed it to BasicHttpBinding. Unfortunately I keep getting this error now: "An error occurred while trying to make a request to URI'**'.This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent." I placed clientaccesspolicy.xml in the root directory of the WCF project (which is in the same solution as the Silverlight client). This did not solve the problem. What do I need to do?

  • TextView defined in main.xml - how to "name" it to be able to use - setText() method?

    - by Oliver Goossens
    Hi, I am exploring android and developement and I found one problem. My app UI is defined in main.xml I have 2 texts and 2 buttons defined - easy app. I read that I may be able to change TEXT in the ACTIVITY using the setText() method. And thats the problem - how do I POINT the setText() Method? How do I tell it to change a specified text? If I would declare the TextView inside the Activity with NEW TextView NAME Object, I would just need to use NAME.setText(STRING)... But I didnt so i dont have anything like NAME of the object? How can this be done? I read something about r.IDs but I truly dont have a idea how to use them, where to find them and how to implement it .... Please advise Thank you Oliver

  • XML Table layout? Two EQUAL-width rows filled with equally width buttons??

    - by Oliver Goossens
    Hi heres a part from my XML for LAND format: <TableLayout android:layout_height="wrap_content" android:layout_width="wrap_content" android:layout_gravity="center" android:stretchColumns="*"> <TableRow> <Button android:id="@+id/countbutton" android:text="@string/plus1"/> <Button android:id="@+id/resetbutton" android:text="@string/reset" /> </TableRow> </TableLayout> And now what I dont get - the WIDTH of one row and also of the button depends on the TEXT inside the button. If the both texts are equaly long lets say : TEXT its ok - the table half is in the middle of the screen. But if they have different size - lets say "A" and "THIS IS THE LONG BUTTON" the CENTER of the table isnt in the middle of the screen anymore and so the buttons are not equally width... Cant find any solution... Please advise... Thank you Oliver Goossens
