• JBoss 7.1.1 + Spring 3.1 + JPA 2 (Hibernate 3.6.8) > Cannot parse beans.xml

  - by Mashrur

  Trying to deploy a JSF 2 app with Spring 3.1 + JPA 2 (Hibernte 3.6.8) into JBoss 7.1.1 AS. The app was working fine on tomcat 7. Now, I have already added and changed some configurations. Added jboss-deployment-structure.xml <jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.1"> <deployment> <exclusions> <module name="org.apache.log4j" /> <module name="javax.faces.api" slot="main"/> <module name="com.sun.jsf-impl" slot="main"/> <module name="org.hibernate"/> <module name="org.javassist" /> <module name="javaee.api" /> <module name="org.hibernate.validator" /> <module name="org.jboss.as.web" /> <module name="org.jboss.logging" /> <module name="javax.persistence.api" /> <module name="org.jboss.interceptor" /> </exclusions> </deployment> </jboss-deployment-structure> 2. Inside web.xml added these lines: <persistence-unit-ref> <persistence-unit-ref-name>persistence/persistenceUnit</persistence-unit-ref-name> <persistence-unit-name>persistenceUnit</persistence-unit-name> </persistence-unit-ref> 3. Inside applicationContext.xml, changed bean definition for entityManagerFactory by adding this property <property name="persistenceXmlLocation" value="classpath*:META-INF/persistence.xml"/> Now, do I still need to do something more than these which is obvious to you? Because, while I am trying to deploy it from eclipse indigo SR2, getting this 14:10:32,046 INFO [org.jboss.modules] JBoss Modules version 1.1.1.GA 14:10:33,054 INFO [org.jboss.msc] JBoss MSC version 1.0.2.GA 14:10:33,200 INFO [org.jboss.as] JBAS015899: JBoss AS 7.1.1.Final "Brontes" starting 14:10:36,375 INFO [org.xnio] XNIO Version 3.0.3.GA 14:10:36,384 INFO [org.jboss.as.server] JBAS015888: Creating http management service using socket-binding (management-http) 14:10:36,432 INFO [org.xnio.nio] XNIO NIO Implementation Version 3.0.3.GA 14:10:36,462 INFO [org.jboss.remoting] JBoss Remoting version 3.2.3.GA 14:10:36,587 INFO [org.jboss.as.logging] JBAS011502: Removing bootstrap log handlers 14:10:36,714 INFO [org.jboss.as.security] (ServerService Thread Pool -- 44) JBAS013101: Activating Security Subsystem 14:10:36,735 INFO [org.jboss.as.naming] (MSC service thread 1-2) JBAS011802: Starting Naming Service 14:10:37,043 INFO [org.jboss.as.mail.extension] (MSC service thread 1-6) JBAS015400: Bound mail session [java:jboss/mail/Default] 14:10:37,208 INFO [org.jboss.as.connector] (MSC service thread 1-7) JBAS010408: Starting JCA Subsystem (JBoss IronJacamar 1.0.9.Final) 14:10:37,295 INFO [org.jboss.as.security] (MSC service thread 1-7) JBAS013100: Current PicketBox version=4.0.7.Final 14:10:37,740 INFO [org.jboss.as.connector.subsystems.datasources] (ServerService Thread Pool -- 27) JBAS010403: Deploying JDBC-compliant driver class org.h2.Driver (version 1.3) 14:10:38,792 INFO [org.jboss.ws.common.management.AbstractServerConfig] (MSC service thread 1-3) JBoss Web Services - Stack CXF Server 4.0.2.GA 14:10:38,833 INFO [org.apache.coyote.http11.Http11Protocol] (MSC service thread 1-2) Starting Coyote HTTP/1.1 on http-localhost-127.0.0.1-8080 14:10:39,534 INFO [org.jboss.as.server.deployment.scanner] (MSC service thread 1-1) JBAS015012: Started FileSystemDeploymentService for directory F:\work\softwares\Application Servers\JBoss\jboss-as-7.1.1.Final\jboss-as-7.1.1.Final\standalone\deployments 14:10:39,618 INFO [org.jboss.as.remoting] (MSC service thread 1-3) JBAS017100: Listening on localhost/127.0.0.1:4447 14:10:39,623 INFO [org.jboss.as.remoting] (MSC service thread 1-2) JBAS017100: Listening on /127.0.0.1:9999 14:10:39,698 INFO [org.jboss.as.server.deployment.scanner] (DeploymentScanner-threads - 1) JBAS015014: Re-attempting failed deployment treasury.war 14:10:39,706 INFO [org.jboss.as.server.deployment.scanner] (DeploymentScanner-threads - 1) JBAS015003: Found com.misl.treasury.ui.war in deployment directory.

• Weird vps server issue

  - by anon-user0

  I have an unmanaged linux vps Ubuntu 11.10 (Oneiric Ocelot). I have LNMP installed. Also php-fpm php-apc, varnish, memcache. I have (or rather had) several live sites on it. under normal load the server uses ~700 mb memory. But since last night its using only 20mb~ memory and a lot of the services seems to be down (according to htop) I only see nginx working and mysql starts up and goes does every few minutes on a loop. Here are some information on the server that might help you help me: root@server:~# uname -a Linux server 2.6.18-308.el5.028stab099.3 #1 SMP Wed Mar 7 15:56:00 MSK 2012 i686 i686 i386 GNU/Linux - root@server:~# ifconfig -a lo Link encap:Local Loopback LOOPBACK MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) venet0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:127.0.0.2 P-t-P:127.0.0.2 Bcast:0.0.0.0 Mask:255.255.255.255 UP BROADCAST POINTOPOINT RUNNING NOARP MTU:1500 Metric:1 RX packets:12515 errors:0 dropped:0 overruns:0 frame:0 TX packets:9541 errors:0 dropped:1 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:7191214 (7.1 MB) TX bytes:536726 (536.7 KB) venet0:0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:176.31.158.78 P-t-P:176.31.158.78 Bcast:0.0.0.0 Mask:255.255.255.255 UP BROADCAST POINTOPOINT RUNNING NOARP MTU:1500 Metric:1 - root@server:~# netstat -l Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 *:http-alt *:* LISTEN tcp 0 0 *:ssh *:* LISTEN tcp6 0 0 [::]:http-alt [::]:* LISTEN tcp6 0 0 [::]:ssh [::]:* LISTEN Active UNIX domain sockets (only servers) Proto RefCnt Flags Type State I-Node Path unix 2 [ ACC ] STREAM LISTENING 9307368 @/com/ubuntu/upstart - htop: http://i.stack.imgur.com/NHKYX.png EDIT: Stressed. mind was not working adding log: root@server:~# less /var/log/syslog Jun 27 05:27:42 server syslogd 1.5.0#6ubuntu1: restart.

• How to programmatically create customcontrol and change its values in Silverlight 4

  - by user361317

  Hi! I want to create a custom tabcontrol class which has an icon before the text, and I want to be able to change the icon in the constructor of the new tabcontrol. I use implicit styles in Silverlight 4, and the custom tabcontrol should not have any xaml of its own, just the class and the implicit xaml style in my App.xaml. I cannot, however, get this to work. This is my code: <!-- Style for generic tabcontrols --> 20,0,0,0 <Style TargetType="controls:TabItem"> <Setter Property="IsTabStop" Value="False"/> <Setter Property="Background" Value="#FFDBEDFB"/>

img; } } This is driving me nuts, and I can't find any examples where anyone has done this without having a xaml page for the custom tab. Is this even possible? Can someone point me in the right direction? Cheers! - jonah

• C# .Net 3.5 Asynchronous Socket Server Performance Problem

  - by iBrAaAa

  I'm developing an Asynchronous Game Server using .Net Socket Asynchronous Model( BeginAccept/EndAccept...etc.) The problem I'm facing is described like that: When I have only one client connected, the server response time is very fast but once a second client connects, the server response time increases too much. I've measured the time from a client sends a message to the server until it gets the reply in both cases. I found that the average time in case of one client is about 17ms and in case of 2 clients about 280ms!!! What I really see is that: When 2 clients are connected and only one of them is moving(i.e. requesting service from the server) it is equivalently equal to the case when only one client is connected(i.e. fast response). However, when the 2 clients move at the same time(i.e. requests service from the server at the same time) their motion becomes very slow (as if the server replies each one of them in order i.e. not simultaneously). Basically, what I am doing is that: When a client requests a permission for motion from the server and the server grants him the request, the server then broadcasts the new position of the client to all the players. So if two clients are moving in the same time, the server is eventually trying to broadcast to both clients the new position of each of them at the same time. EX: Client1 asks to go to position (2,2) Client2 asks to go to position (5,5) Server sends to each of Client1 & Client2 the same two messages: message1: "Client1 at (2,2)" message2: "Client2 at (5,5)" I believe that the problem comes from the fact that Socket class is thread safe according MSDN documentation http://msdn.microsoft.com/en-us/library/system.net.sockets.socket.aspx. (NOT SURE THAT IT IS THE PROBLEM) Below is the code for the server: /// /// This class is responsible for handling packet receiving and sending /// public class NetworkManager { /// /// An integer to hold the server port number to be used for the connections. Its default value is 5000. /// private readonly int port = 5000; /// /// hashtable contain all the clients connected to the server. /// key: player Id /// value: socket /// private readonly Hashtable connectedClients = new Hashtable();

• half or quarter black screen in android

  - by Mike McKeown

  I have an android activity that when I launch sometimes (about 1 in 4 times) it only draws quarter or half the screen before showing it. When I change the orientation or press a button the screen draws properly. I'm just using TextViews, Buttons, Fonts - no drawing or anything like that. All of my code for initialising is in the onCreate(). In this method I'm loading a text file, of about 40 lines long, and also getting a shared preference. Could this cause a delay so that it can't draw the intent? Thanks in advance if anyone has seen anything similar. EDIT - I tried commenting out the loading of the word list, but it didn't fix the problem. Here is the activity <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/mainRelativeLayout"

• JPA : optimize EJB-QL query involving large many-to-many join table

  - by Fabien

  Hi all. I'm using Hibernate Entity Manager 3.4.0.GA with Spring 2.5.6 and MySql 5.1. I have a use case where an entity called Artifact has a reflexive many-to-many relation with itself, and the join table is quite large (1 million lines). As a result, the HQL query performed by one of the methods in my DAO takes a long time. Any advice on how to optimize this and still use HQL ? Or do I have no choice but to switch to a native SQL query that would perform a join between the table ARTIFACT and the join table ARTIFACT_DEPENDENCIES ? Here is the problematic query performed in the DAO : @SuppressWarnings("unchecked") public List<Artifact> findDependentArtifacts(Artifact artifact) { Query query = em.createQuery("select a from Artifact a where :artifact in elements(a.dependencies)"); query.setParameter("artifact", artifact); List<Artifact> list = query.getResultList(); return list; } And the code for the Artifact entity : package com.acme.dependencytool.persistence.model; import java.util.ArrayList; import java.util.List; import javax.persistence.CascadeType; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.FetchType; import javax.persistence.GeneratedValue; import javax.persistence.Id; import javax.persistence.JoinColumn; import javax.persistence.JoinTable; import javax.persistence.ManyToMany; import javax.persistence.Table; import javax.persistence.UniqueConstraint; @Entity @Table(name = "ARTIFACT", uniqueConstraints={@UniqueConstraint(columnNames={"GROUP_ID", "ARTIFACT_ID", "VERSION"})}) public class Artifact { @Id @GeneratedValue @Column(name = "ID") private Long id = null; @Column(name = "GROUP_ID", length = 255, nullable = false) private String groupId; @Column(name = "ARTIFACT_ID", length = 255, nullable = false) private String artifactId; @Column(name = "VERSION", length = 255, nullable = false) private String version; @ManyToMany(cascade=CascadeType.ALL, fetch=FetchType.EAGER) @JoinTable( name="ARTIFACT_DEPENDENCIES", joinColumns = @JoinColumn(name="ARTIFACT_ID", referencedColumnName="ID"), inverseJoinColumns = @JoinColumn(name="DEPENDENCY_ID", referencedColumnName="ID") ) private List<Artifact> dependencies = new ArrayList<Artifact>(); public Long getId() { return id; } public void setId(Long id) { this.id = id; } public String getGroupId() { return groupId; } public void setGroupId(String groupId) { this.groupId = groupId; } public String getArtifactId() { return artifactId; } public void setArtifactId(String artifactId) { this.artifactId = artifactId; } public String getVersion() { return version; } public void setVersion(String version) { this.version = version; } public List<Artifact> getDependencies() { return dependencies; } public void setDependencies(List<Artifact> dependencies) { this.dependencies = dependencies; } } Thanks in advance. EDIT 1 : The DDLs are generated automatically by Hibernate EntityMananger based on the JPA annotations in the Artifact entity. I have no explicit control on the automaticaly-generated join table, and the JPA annotations don't let me explicitly set an index on a column of a table that does not correspond to an actual Entity (in the JPA sense). So I guess the indexing of table ARTIFACT_DEPENDENCIES is left to the DB, MySQL in my case, which apparently uses a composite index based on both clumns but doesn't index the column that is most relevant in my query (DEPENDENCY_ID). mysql describe ARTIFACT_DEPENDENCIES; +---------------+------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +---------------+------------+------+-----+---------+-------+ | ARTIFACT_ID | bigint(20) | NO | MUL | NULL | | | DEPENDENCY_ID | bigint(20) | NO | MUL | NULL | | +---------------+------------+------+-----+---------+-------+ EDIT 2 : When turning on showSql in the Hibernate session, I see many occurences of the same type of SQL query, as below : select dependenci0_.ARTIFACT_ID as ARTIFACT1_1_, dependenci0_.DEPENDENCY_ID as DEPENDENCY2_1_, artifact1_.ID as ID1_0_, artifact1_.ARTIFACT_ID as ARTIFACT2_1_0_, artifact1_.GROUP_ID as GROUP3_1_0_, artifact1_.VERSION as VERSION1_0_ from ARTIFACT_DEPENDENCIES dependenci0_ left outer join ARTIFACT artifact1_ on dependenci0_.DEPENDENCY_ID=artifact1_.ID where dependenci0_.ARTIFACT_ID=? Here's what EXPLAIN in MySql says about this type of query : mysql explain select dependenci0_.ARTIFACT_ID as ARTIFACT1_1_, dependenci0_.DEPENDENCY_ID as DEPENDENCY2_1_, artifact1_.ID as ID1_0_, artifact1_.ARTIFACT_ID as ARTIFACT2_1_0_, artifact1_.GROUP_ID as GROUP3_1_0_, artifact1_.VERSION as VERSION1_0_ from ARTIFACT_DEPENDENCIES dependenci0_ left outer join ARTIFACT artifact1_ on dependenci0_.DEPENDENCY_ID=artifact1_.ID where dependenci0_.ARTIFACT_ID=1; +----+-------------+--------------+--------+-------------------+-------------------+---------+---------------------------------------------+------+-------+ | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra | +----+-------------+--------------+--------+-------------------+-------------------+---------+---------------------------------------------+------+-------+ | 1 | SIMPLE | dependenci0_ | ref | FKEA2DE763364D466 | FKEA2DE763364D466 | 8 | const | 159 | | | 1 | SIMPLE | artifact1_ | eq_ref | PRIMARY | PRIMARY | 8 | dependencytooldb.dependenci0_.DEPENDENCY_ID | 1 | | +----+-------------+--------------+--------+-------------------+-------------------+---------+---------------------------------------------+------+-------+ EDIT 3 : I tried setting the FetchType to LAZY in the JoinTable annotation, but I then get the following exception : Hibernate: select artifact0_.ID as ID1_, artifact0_.ARTIFACT_ID as ARTIFACT2_1_, artifact0_.GROUP_ID as GROUP3_1_, artifact0_.VERSION as VERSION1_ from ARTIFACT artifact0_ where artifact0_.GROUP_ID=? and artifact0_.ARTIFACT_ID=? 51545 [btpool0-2] ERROR org.hibernate.LazyInitializationException - failed to lazily initialize a collection of role: com.acme.dependencytool.persistence.model.Artifact.dependencies, no session or session was closed org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: com.acme.dependencytool.persistence.model.Artifact.dependencies, no session or session was closed at org.hibernate.collection.AbstractPersistentCollection.throwLazyInitializationException(AbstractPersistentCollection.java:380) at org.hibernate.collection.AbstractPersistentCollection.throwLazyInitializationExceptionIfNotConnected(AbstractPersistentCollection.java:372) at org.hibernate.collection.AbstractPersistentCollection.readSize(AbstractPersistentCollection.java:119) at org.hibernate.collection.PersistentBag.size(PersistentBag.java:248) at com.acme.dependencytool.server.DependencyToolServiceImpl.createArtifactViewBean(DependencyToolServiceImpl.java:93) at com.acme.dependencytool.server.DependencyToolServiceImpl.createArtifactViewBean(DependencyToolServiceImpl.java:109) at com.acme.dependencytool.server.DependencyToolServiceImpl.search(DependencyToolServiceImpl.java:48) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at com.google.gwt.user.server.rpc.RPC.invokeAndEncodeResponse(RPC.java:527) at com.google.gwt.user.server.rpc.RemoteServiceServlet.processCall(RemoteServiceServlet.java:166) at com.google.gwt.user.server.rpc.RemoteServiceServlet.doPost(RemoteServiceServlet.java:86) at javax.servlet.http.HttpServlet.service(HttpServlet.java:637) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.mortbay.jetty.servlet.ServletHolder.handle(ServletHolder.java:487) at org.mortbay.jetty.servlet.ServletHandler.handle(ServletHandler.java:362) at org.mortbay.jetty.security.SecurityHandler.handle(SecurityHandler.java:216) at org.mortbay.jetty.servlet.SessionHandler.handle(SessionHandler.java:181) at org.mortbay.jetty.handler.ContextHandler.handle(ContextHandler.java:729) at org.mortbay.jetty.webapp.WebAppContext.handle(WebAppContext.java:405) at org.mortbay.jetty.handler.HandlerWrapper.handle(HandlerWrapper.java:152) at org.mortbay.jetty.handler.RequestLogHandler.handle(RequestLogHandler.java:49) at org.mortbay.jetty.handler.HandlerWrapper.handle(HandlerWrapper.java:152) at org.mortbay.jetty.Server.handle(Server.java:324) at org.mortbay.jetty.HttpConnection.handleRequest(HttpConnection.java:505) at org.mortbay.jetty.HttpConnection$RequestHandler.content(HttpConnection.java:843) at org.mortbay.jetty.HttpParser.parseNext(HttpParser.java:647) at org.mortbay.jetty.HttpParser.parseAvailable(HttpParser.java:205) at org.mortbay.jetty.HttpConnection.handle(HttpConnection.java:380) at org.mortbay.io.nio.SelectChannelEndPoint.run(SelectChannelEndPoint.java:395) at org.mortbay.thread.QueuedThreadPool$PoolThread.run(QueuedThreadPool.java:488)

• CSS IE Hover Effect - Overlapping Elements, Display:Block, and Crashes

  - by Emtucifor

  In a fairly simple page, I have some text appear on hover over some links, like a tooltip. To start with here's my test page I'm working with: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <title>Tooltip Test Page</title> <style type="text/css"> html, body, form, table, tr, td, div, p, h1, h2, h3, h4, h5 { border:0; margin:0; padding:0; } body { margin:10px; } html, body, table { font-family:Arial, Helvetica, sans-serif; font-size:12px; } h1 { font-weight:bold; font-size:16px; } table {border-collapse:collapse;} td {padding:0 8px 0 0;} a.tooltip { z-index:24; text-decoration:none; cursor:default; position:relative; color:#000; display:block; width:100px; } a.tooltip span {display:none;} a.tooltip:hover, a.tooltip:active { z-index:25; color:; background:; /* the color and background actually don't matter for their values, it's just that these have to change for IE to apply this style properly. Leaving out the color or the background makes this fail in different ways. */ } a.tooltip:hover span, a.tooltip:active span { display:block; position:absolute; color:black; background-color:#FFFFCC; border:1px solid black; padding:1px; text-align:left; top:0; left:0; margin-top:-1px; } td span.s5 {color:#ff0000} td span.s6 {color:#0000ff} </style> <script type="text/javascript"> function labelSubmit(label) { document.getElementById('o').value=label; document.BackAt.submit(); } </script> </head> <body> <h1>tooltip Test Page</h1> <table> <tbody> <tr> <td><span class="s6">&#x25a0;</span> Name 3</td> <td class="status"><a class="tooltip" href="" onclick="return false;">Status 6<span>Some very long tooltip text to demonstrate the problem by overlapping the cells below.</span></a></td> </tr> <tr> <td><span class="s6">&#x25a0;</span> Name 1</td> <td class="status"><a class="tooltip" href="" onclick="return false;">Status 6</a></td> </tr> <tr> <td><span class="s6">&#x25a0;</span> Name 2</td> <td class="status"><a class="tooltip" href="" onclick="return false;">Status 6<span>Some tooltip text</span></a></td> </tr> <tr> <td><span class="s6">&#x25a0;</span> Name 4</td> <td class="status"><a class="tooltip" href="" onclick="return false;">Status 6</a></td> </tr> <tr> <td><span class="s5">&#x25a0;</span> Name 5</td> <td class="status"><a class="tooltip" href="" onclick="return false;">Status 5<span>More Notes</span></a></td> </tr> <tr> <td><span class="s6">&#x25a0;</span> Name 6</td> <td class="status"><a class="tooltip" href="" onclick="return false;">Status 6<span>Yet more notes</span></a></td> </tr> </tbody> </table> </body> </html> The problem I'm experiencing is that text from other values shows through the tooltip text. Hover over the first row, second column to see the effect. There are a couple of things I'm trying to accomplish: Make the activation area for the hover wider, so hovering over some space to the right of "Status 6" calls up the tooltip (say, 100-150px total width of target). At first, when I was adding "display:block" to a.tooltip, IE was terminating on hover. I resolved that by removing width:14em from a.tooltip:hover. Styling the width of the hover event + display.block on the a element does BAD things. Change the width of the tooltip without changing the width of the column/parent element (so the tooltip can be wider than itso it takes up less vertical space). Options for making the tooltips change width with its contents up to a max width, at which point the lines wrap would be awesome, but probably impossible in IE. As soon as I put a width in place on a.tooltip, the portion of the tooltip that is above other rows than the hover source let text show through from those cells. Remove the width and you'll see that the text doesn't show through any more. The hover effect applies to the entire tooltip, so if the tooltip covers 3 rows, while moving the mouse downward, the next 2 rows won't activate because the cursor hasn't left the tooltip. Can the hover effect apply only to the initial element hovered over and not the tooltip itself so moving the mouse downward will show each tooltip in each row? It would be nice if the links could never be activated (they can't take the focus). I don't know if that's possible. Too bad IE doesn't support hover on any elements but links. Note: soon IE6 will be abandoned in favor of IE8. If it makes a big difference, then IE8 can be the target browser instead. Thanks for your help.

• SPP Socket createRfcommSocketToServiceRecord will not connect

  - by philDev

  Hello, I want to use Android 2.1 to connect to an external Bluetooth device, wich is offering an SPP port to me. In this case it is an external GPS unit. When I'm trying to connect I can't connect an established socket while being in the "client" mode. Then if I try to set up a socket (being in the server role), to RECEIVE text from my PC everything works just fine. The Computer can connect as the client to the Socket on the Phone via SPP using the SSP UUID or some random UUID. So the Problem is not that I'm using the wrong UUID. But the other way around (e.g. calling connect on the established client socket) createRfcommSocketToServiceRecord(UUID uuid)) just doesn't work. Sadly I don't have the time to inspect the problem further. It would be greate If somebody could point me the right way. In the following part of the Logfile has to be the Problem. Greets PhilDev P.S. I'm going to be present during the Office hours. Here the log file: 03-21 03:10:52.020: DEBUG/BluetoothSocket.cpp(4643): initSocketFromFdNative 03-21 03:10:52.025: DEBUG/BluetoothSocket(4643): connect 03-21 03:10:52.025: DEBUG/BluetoothSocket(4643): doSdp 03-21 03:10:52.050: DEBUG/ADAPTER(2132): create_device(01:00:00:7F:B5:B3) 03-21 03:10:52.050: DEBUG/ADAPTER(2132): adapter_create_device(01:00:00:7F:B5:B3) 03-21 03:10:52.055: DEBUG/DEVICE(2132): Creating device [address = 01:00:00:7F:B5:B3] /org/bluez/2132/hci0/dev_01_00_00_7F_B5_B3 [name = ] 03-21 03:10:52.055: DEBUG/DEVICE(2132): btd_device_ref(0x10c18): ref=1 03-21 03:10:52.065: INFO/BluetoothEventLoop.cpp(1914): event_filter: Received signal org.bluez.Adapter:DeviceCreated from /org/bluez/2132/hci0 03-21 03:10:52.065: INFO/BluetoothService.cpp(1914): ...

• C# WCF Server retrieves 'List<T>' with 1 entry, but client doesn't receive it?! Please help Urgentl

  - by Neville

  Hi Everyone, I've been battling and trying to research this issue for over 2 days now with absolutely no luck. I am trying to retrieve a list of clients from the server (server using fluentNHibernate). The client object is as follow: [DataContract] //[KnownType(typeof(System.Collections.Generic.List<ContactPerson>))] //[KnownType(typeof(System.Collections.Generic.List<Address>))] //[KnownType(typeof(System.Collections.Generic.List<BatchRequest>))] //[KnownType(typeof(System.Collections.Generic.List<Discount>))] [KnownType(typeof(EClientType))] [KnownType(typeof(EComType))] public class Client { #region Properties [DataMember] public virtual int ClientID { get; set; } [DataMember] public virtual EClientType ClientType { get; set; } [DataMember] public virtual string RegisterID {get; set;} [DataMember] public virtual string HerdCode { get; set; } [DataMember] public virtual string CompanyName { get; set; } [DataMember] public virtual bool InvoicePerBatch { get; set; } [DataMember] public virtual EComType ResultsComType { get; set; } [DataMember] public virtual EComType InvoiceComType { get; set; } //[DataMember] //public virtual IList<ContactPerson> Contacts { get; set; } //[DataMember] //public virtual IList<Address> Addresses { get; set; } //[DataMember] //public virtual IList<BatchRequest> Batches { get; set; } //[DataMember] //public virtual IList<Discount> Discounts { get; set; } #endregion #region Overrides public override bool Equals(object obj) { var other = obj as Client; if (other == null) return false; return other.GetHashCode() == this.GetHashCode(); } public override int GetHashCode() { return ClientID.GetHashCode() | ClientType.GetHashCode() | RegisterID.GetHashCode() | HerdCode.GetHashCode() | CompanyName.GetHashCode() | InvoicePerBatch.GetHashCode() | ResultsComType.GetHashCode() | InvoiceComType.GetHashCode();// | Contacts.GetHashCode() | //Addresses.GetHashCode() | Batches.GetHashCode() | Discounts.GetHashCode(); } #endregion } As you can see, I have allready tried to remove the sub-lists, though even with this simplified version of the client I still run into the propblem. my fluent mapping is: public class ClientMap : ClassMap<Client> { public ClientMap() { Table("Clients"); Id(p => p.ClientID); Map(p => p.ClientType).CustomType<EClientType>(); ; Map(p => p.RegisterID); Map(p => p.HerdCode); Map(p => p.CompanyName); Map(p => p.InvoicePerBatch); Map(p => p.ResultsComType).CustomType<EComType>(); Map(p => p.InvoiceComType).CustomType<EComType>(); //HasMany<ContactPerson>(p => p.Contacts) // .KeyColumns.Add("ContactPersonID") // .Inverse() // .Cascade.All(); //HasMany<Address>(p => p.Addresses) // .KeyColumns.Add("AddressID") // .Inverse() // .Cascade.All(); //HasMany<BatchRequest>(p => p.Batches) // .KeyColumns.Add("BatchID") // .Inverse() // .Cascade.All(); //HasMany<Discount>(p => p.Discounts) // .KeyColumns.Add("DiscountID") // .Inverse() // .Cascade.All(); } The client method, seen below, connects to the server. The server retrieves the list, and everything looks right in the object, still, when it returns, the client doesn't receive anything (it receive a List object, but with nothing in it. Herewith the calling method: public List<s.Client> GetClientList() { try { s.DataServiceClient svcClient = new s.DataServiceClient(); svcClient.Open(); List<s.Client> clients = new List<s.Client>(); clients = svcClient.GetClientList().ToList<s.Client>(); svcClient.Close(); //when receiving focus from server, the clients object has a count of 0 return clients; } catch (Exception e) { MessageBox.Show(e.Message); } return null; } and the server method: public IList<Client> GetClientList() { var clients = new List<Client>(); try { using (var session = SessionHelper.OpenSession()) { clients = session.Linq<Client>().Where(p => p.ClientID > 0).ToList<Client>(); } } catch (Exception e) { EventLog.WriteEntry("eCOWS.Data", e.Message); } return clients; //returns a list with 1 client in it } the server method interface is: [UseNetDataContractSerializer] [OperationContract] IList<Client> GetClientList(); for final references, here is my client app.config entries: <system.serviceModel> <bindings> <netTcpBinding> <binding name="NetTcpBinding_IDataService" listenBacklog="10" maxConnections="10" transferMode="Buffered" transactionProtocol="OleTransactions" maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" receiveTimeout="00:10:00" sendTimeout="00:10:00"> <readerQuotas maxDepth="51200000" maxStringContentLength="51200000" maxArrayLength="51200000" maxBytesPerRead="51200000" maxNameTableCharCount="51200000" /> <security mode="Transport"/> </binding> </netTcpBinding> </bindings> <client> <endpoint address="net.tcp://localhost:9000/eCOWS/DataService" binding="netTcpBinding" bindingConfiguration="NetTcpBinding_IDataService" contract="eCowsDataService.IDataService" name="NetTcpBinding_IDataService" behaviorConfiguration="eCowsEndpointBehavior"> </endpoint> <endpoint address="MEX" binding="mexHttpBinding" contract="IMetadataExchange" /> </client> <behaviors> <endpointBehaviors> <behavior name="eCowsEndpointBehavior"> <dataContractSerializer maxItemsInObjectGraph="2147483647"/> </behavior> </endpointBehaviors> </behaviors> </system.serviceModel> and my server app.config: <system.serviceModel> <bindings> <netTcpBinding> <binding name="netTcpBinding" maxConnections="10" listenBacklog="10" transferMode="Buffered" transactionProtocol="OleTransactions" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" sendTimeout="00:10:00" receiveTimeout="00:10:00"> <readerQuotas maxDepth="51200000" maxStringContentLength="51200000" maxArrayLength="51200000" maxBytesPerRead="51200000" maxNameTableCharCount="51200000" /> <security mode="Transport"/> </binding> </netTcpBinding> </bindings> <services> <service name="eCows.Data.Services.DataService" behaviorConfiguration="eCowsServiceBehavior"> <host> <baseAddresses> <add baseAddress="http://localhost:9001/eCOWS/" /> <add baseAddress="net.tcp://localhost:9000/eCOWS/" /> </baseAddresses> </host> <endpoint address="DataService" binding="netTcpBinding" contract="eCows.Data.Services.IDataService" behaviorConfiguration="eCowsEndpointBehaviour"> </endpoint> <endpoint address="MEX" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> <behaviors> <endpointBehaviors> <behavior name="eCowsEndpointBehaviour"> <dataContractSerializer maxItemsInObjectGraph="2147483647" /> </behavior> </endpointBehaviors> <serviceBehaviors> <behavior name="eCowsServiceBehavior"> <serviceMetadata httpGetEnabled="True"/> <serviceThrottling maxConcurrentCalls="10" maxConcurrentSessions="10"/> <serviceDebug includeExceptionDetailInFaults="False" /> </behavior> <behavior name="MexBehaviour"> <serviceMetadata /> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel> I use to run into "socket closed / network or timeout" errors, and the trace showed clearly that on the callback it was looking for a listening endpoint, but couldn't find one. Anyway, after adding the UseNetSerializer that error went away, yet now I'm just not getting anything. Oh PS. if I add all the commented out List items, I still retrieve an entry from the DB, but also still not receive anything on the client. if I remove the [UseNetDataContractSerializer] I get the following error(s) in the svclog : WARNING: Description Faulted System.ServiceModel.Channels.ServerSessionPreambleConnectionReader+ServerFramingDuplexSessionChannel WARNING: Description Faulted System.ServiceModel.Channels.ServiceChannel ERROR: Initializing[eCows.Data.Models.Client#3]-failed to lazily initialize a collection of role: eCows.Data.Models.Client.Addresses, no session or session was closed ... ERROR: Could not find default endpoint element that references contract 'ILogbookManager' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element. If I add a .Not.LazyLoad to the List mapping items, I'm back at not receiving errors, but also not receiving any client information.. Sigh! Please, if anyone can help with this I'd be extremely grateful. I'm probably just missing something small.. but... what is it :) hehe. Thanks in advance! Neville

• C# serial port driver wrapper class code and concept quality

  Hi folks, Would like to know from all you guys what you think about my Serial Wrapper class. Had be a while I've beem working with serial port but never shared the code what somekind make closed to my very own vision. Would like to know if it's a good/bad approach, if the interface is enough and what more you see on it. I know that Stackoverflow is for question but at the same time there's a lot of very good skilled people here and share code and opinion can also bennefit everybody, it's why I decided to post it anyway. thanks! using System.Text; using System.IO; using System.IO.Ports; using System; namespace Driver { class SerialSingleton { // The singleton instance reference private static SerialSingleton instance = null; // System's serial port interface private SerialPort serial; // Current com port identifier private string comPort = null; // Configuration parameters private int confBaudRate; private int confDataBits; private StopBits confStopBits; private Parity confParityControl; ASCIIEncoding encoding = new ASCIIEncoding(); // ================================================================================== // Constructors public static SerialSingleton getInstance() { if (instance == null) { instance = new SerialSingleton(); } return instance; } private SerialSingleton() { serial = new SerialPort(); } // =================================================================================== // Setup Methods public string ComPort { get { return comPort; } set { if (value == null) { throw new SerialException("Serial port name canot be null."); } if (nameIsComm(value)) { close(); comPort = value; } else { throw new SerialException("Serial Port '" + value + "' is not a valid com port."); } } } public void setSerial(string baudRate, int dataBits, StopBits stopBits, Parity parityControl) { if (baudRate == null) { throw new SerialException("Baud rate cannot be null"); } string[] baudRateRef = { "300", "600", "1200", "1800", "2400", "3600", "4800", "7200", "9600", "14400", "19200", "28800", "38400", "57600", "115200" }; int confBaudRate; if (findString(baudRateRef, baudRate) != -1) { confBaudRate = System.Convert.ToInt32(baudRate); } else { throw new SerialException("Baurate parameter invalid."); } int confDataBits; switch (dataBits) { case 5: confDataBits = 5; break; case 6: confDataBits = 6; break; case 7: confDataBits = 7; break; case 8: confDataBits = 8; break; default: throw new SerialException("Databits parameter invalid"); } if (stopBits == StopBits.None) { throw new SerialException("StopBits parameter cannot be NONE"); } this.confBaudRate = confBaudRate; this.confDataBits = confDataBits; this.confStopBits = stopBits; this.confParityControl = parityControl; } // ================================================================================== public string[] PortList { get { return SerialPort.GetPortNames(); } } public int PortCount { get { return SerialPort.GetPortNames().Length; } } // ================================================================================== // Open/Close Methods public void open() { open(comPort); } private void open(string comPort) { if (isOpen()) { throw new SerialException("Serial Port is Already open"); } else { if (comPort == null) { throw new SerialException("Serial Port not defined.

• Inheritance of templates in WPF

  - by Alxandr

  I'm trying to make sure that every child of a given element (MPF.MWindow) gets custom templates. For instance, the button should get the template defined in resMButton.xaml. As of now I'm using the following code on: (resMWindow.xaml) <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:MPF"> <Style x:Key="SystemKeyAnimations" TargetType="{x:Type Button}"> <Setter Property="Opacity" Value="0.5" /> <Setter Property="Background" Value="Transparent" /> <Style.Triggers> <EventTrigger RoutedEvent="Mouse.MouseEnter"> <BeginStoryboard> <Storyboard> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetProperty="Opacity"> <SplineDoubleKeyFrame KeyTime="00:00:00.2" Value="1.0" /> </DoubleAnimationUsingKeyFrames> </Storyboard> </BeginStoryboard> </EventTrigger> <EventTrigger RoutedEvent="Mouse.MouseLeave"> <BeginStoryboard> <Storyboard> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetProperty="Opacity"> <SplineDoubleKeyFrame KeyTime="00:00:00.2" Value="0.5" /> </DoubleAnimationUsingKeyFrames> </Storyboard> </BeginStoryboard> </EventTrigger> </Style.Triggers> </Style> <Style TargetType="{x:Type local:MWindow}"> <!-- Remove default frame appearance --> <Setter Property="WindowStyle" Value="None" /> <Setter Property="AllowsTransparency" Value="True" /> <Setter Property="Background" Value="Transparent" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type local:MWindow}"> <Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" x:Name="ChromeBorder"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="4" /> <ColumnDefinition /> <ColumnDefinition Width="4" /> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition Height="4" /> <RowDefinition /> <RowDefinition Height="4" /> </Grid.RowDefinitions> <Thumb Grid.Row="0" Grid.Column="1" x:Name="TopThumb" Cursor="SizeNS" BorderThickness="4" BorderBrush="Transparent" /> <Thumb Grid.Row="2" Grid.Column="1" x:Name="BottomThumb" Cursor="SizeNS" BorderThickness="4" BorderBrush="Transparent" /> <Thumb Grid.Row="1" Grid.Column="0" x:Name="LeftThumb" Cursor="SizeWE" BorderThickness="4" BorderBrush="Transparent" /> <Thumb Grid.Row="1" Grid.Column="2" x:Name="RightThumb" Cursor="SizeWE" BorderThickness="4" BorderBrush="Transparent" /> <Thumb Grid.Row="0" Grid.Column="0" x:Name="TopLeftThumb" Cursor="SizeNWSE" BorderThickness="5" BorderBrush="Transparent" /> <Thumb Grid.Row="0" Grid.Column="2" x:Name="TopRightThumb" Cursor="SizeNESW" BorderThickness="5" BorderBrush="Transparent" /> <Thumb Grid.Row="2" Grid.Column="0" x:Name="BottomLeftThumb" Cursor="SizeNESW" BorderThickness="5" BorderBrush="Transparent" /> <Thumb Grid.Row="2" Grid.Column="2" x:Name="BottomRightThumb" Cursor="SizeNWSE" BorderThickness="5" BorderBrush="Transparent" /> <Grid Grid.Row="1" Grid.Column="1"> <Grid.RowDefinitions> <RowDefinition Height="20" /> <RowDefinition /> </Grid.RowDefinitions> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition /> <ColumnDefinition Width="Auto" /> </Grid.ColumnDefinitions> <StackPanel Orientation="Horizontal" Grid.Column="1"> <Button Command="local:WindowCommands.Minimize" Style="{StaticResource ResourceKey=SystemKeyAnimations}"> <Button.Template> <ControlTemplate> <Canvas Width="10" Height="10" Margin="5" Background="Transparent"> <Line X1="0" X2="10" Y1="5" Y2="5" Stroke="White" StrokeThickness="2" /> </Canvas> </ControlTemplate> </Button.Template> </Button> <Button Command="local:WindowCommands.Maximize" x:Name="MaximizeButton" Style="{StaticResource ResourceKey=SystemKeyAnimations}"> <Button.Template> <ControlTemplate> <Canvas Width="10" Height="10" Margin="5" Background="Transparent"> <Rectangle Width="10" Height="10" Stroke="White" StrokeThickness="2" /> </Canvas> </ControlTemplate> </Button.Template> </Button> <Button Command="ApplicationCommands.Close" Style="{StaticResource ResourceKey=SystemKeyAnimations}"> <Button.Template> <ControlTemplate> <Canvas Width="10" Height="10" Margin="5" Background="Transparent"> <Line X1="0" X2="10" Y1="0" Y2="10" Stroke="White" StrokeThickness="2" /> <Line X1="10" X2="0" Y1="0" Y2="10" Stroke="White" StrokeThickness="2" /> </Canvas> </ControlTemplate> </Button.Template> </Button> </StackPanel> <ContentControl x:Name="TitleContentControl"> <TextBlock Text="{TemplateBinding Title}" Foreground="DarkGray" Margin="5,0" /> </ContentControl> </Grid> <ContentPresenter Content="{TemplateBinding Content}" Grid.Row="1"> <ContentPresenter.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="/MPF;component/Themes/resMWindowContent.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </ContentPresenter.Resources> </ContentPresenter> </Grid> </Grid> </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> </ResourceDictionary> As you can see during the ContentPresenter which gets the content of the window I merge in a dicrionary called resMWindowContent.xaml. The resMWindowContent.xaml looks as following: <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:MPF"> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="/MPF;component/Themes/resMButton.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> It simply merges in the resMButton.xaml dictionary (this is done because in the feature I will have MTextBox, mList... and I want to separate them). The resMButton.xaml looks as following: <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:MPF"> <Style TargetType="{x:Type Button}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type Button}"> <Grid Background="Transparent"> <Rectangle Stroke="{TemplateBinding BorderBrush}" StrokeThickness="{TemplateBinding BorderThickness}" Fill="{TemplateBinding Background}" /> <ContentPresenter Content="{TemplateBinding Content}" Margin="3" /> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style> </ResourceDictionary> A simple template drawing a square button. However, it isn't applied at all. My buttons remain normal, and I don't understand what I'm doing wrong. I just want every button inside the MWindow to get a special style (and in time every textbox and so forth). How do I achieve this? One note though: It's important that the styles doesn't apply to elements outside an MWindow.

  I may be asking the impossible but let me set out my problem: I have a menu in a MasterPage which uses images and mouseover mouseout events for design purposes. On one of the menu options I need to display a set of sub menus options on the click of the parent menu item. The menu item itself also needs to navigate to a specified url. I was originally trying to use an AJAX accordion panel but as I only had one accordion panel it was always displaying the sub menu items and was not collapsing. I have also tried putting the options in a div and setting the display via javascript. This worked but then was overwritten once the page navigation postback occurred. Here is the source: <%@ Master Language="VB" CodeFile="MasterPage.master.vb" Inherits="MasterPage" %> <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <%@ Register Src="LeadHeader.ascx" TagName="LeadHeader" TagPrefix="uc1" %> <%@ Register Src="~/LeadFooter.ascx" TagName="LeadFooter" TagPrefix="uc2" %> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <link href="StyleSheet.css" rel="stylesheet" type="text/css" /> <script type="text/javascript"> var revert = new Array(); var inames = new Array('home', 'whoweare', 'whatwedo','ourapproach', 'ourvalues', 'contact'); // Preload if (document.images) { var flipped = new Array(); for(i=0; i< inames.length; i++) { flipped[i] = new Image(); flipped[i].src = "images/"+inames[i]+"2.jpg"; } } function over(num) { if(document.images) { revert[num] = document.images[inames[num]].src; document.images[inames[num]].src = flipped[num].src; } } function out(num) { if(document.images) document.images[inames[num]].src = revert[num]; } function ShowHide(elementId) { var element = document.getElementById(elementId); if(element.style.display != "block") { element.style.display = "block"; } else { element.style.display = "none"; } } function UpdateText(element) { if(element.innerHTML.indexOf("Show") != -1) { element.innerHTML = "Hide Details"; } else { element.innerHTML = "Show Details"; } } </script> </head> <body> <form id="form1" runat="server"> <div> <asp:ContentPlaceHolder ID="ContentPlaceHolder2" runat="server"> <uc1:LeadHeader ID="LeadHeader" runat="server" /> </asp:ContentPlaceHolder> <div id="nav"> <div class="menu-item"> <a href="Default.aspx"> <img src="Images/home.jpg" alt="home" id="home" onmouseover="over(0)" onmouseout="out(0)" class="right" /></a> </div> <div class="menu-item"> <a href="AboutUs.aspx"> <img src="Images/whoweare.jpg" alt="who we are" id="whoweare" onmouseover="over(1)" onmouseout="out(1)" class="right" /></a> </div> <%-- <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <cc1:Accordion ID="Accordion1" runat="server" AutoSize="None" FadeTransitions="true" TransitionDuration="350" FramesPerSecond="40" RequireOpenedPane="false" > <Panes> <cc1:AccordionPane runat="server"> <Header>--%> <div class="menu-item"> <a href="WhatWeDo.aspx"> <img src="Images/whatwedo.jpg" alt="what we do" id="whatwedo" onmouseover="over(2)" onmouseout="out(2)" class="right" onclick="ShowHide('divDetails');UpdateText(this);" /></a></div> <%--/Header> <Content>--%> <div id="divDetails" style="display:none;"> <a href="management.aspx" title="Management Development">Management Development</a><br /> <a href="leadership.aspx" title="Leadership Development">Leadership Development</a><br /> <a href="personal.aspx" title="Personal Development">Personal Development</a><br /> <a href="realteams.aspx" title="Team Building / Facilitation">Team Building & Facilitation</a><br /> <a href="coaching.aspx" title="Coaching">One to One Coaching</a> </div> <%-- </Content> </cc1:AccordionPane> </Panes> </cc1:Accordion> --%> <div class="menu-item"> <a href="OurApproach.aspx"> <img src="images/ourapproach.jpg" alt="our approach" id="ourapproach" onmouseover="over(3)" onmouseout="out(3)" /></a> </div> <div class="menu-item"> <a href="OurValues.aspx"> <img src="images/ourvalues.jpg" alt="our values" id="ourvalues" onmouseover="over(4)" onmouseout="out(4)" /></a> </div> <div class="menu-item"> <a href="ContactUs.aspx"> <img src="images/ContactUs.jpg" alt="contact us" id="contactus" onmouseover="over(5)" onmouseout="out(5)" /></a> </div> </div> <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server"> </asp:ContentPlaceHolder> <asp:ContentPlaceHolder ID="ContentPlaceHolder3" runat="server"> <uc2:LeadFooter ID="LeadFooter" runat="server" /> </asp:ContentPlaceHolder> </div> </form> </body> </html>

• 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.

• DHCP settings out of range Internet shuts off after a few minutes

  - by user263115

  I recently upgraded from windows eight to windows 8.1 I do not know if this has anything to do with anything I have a 64 bit OS. My Internet goes off by itself every 5 minutes even though my wireless icon at the lower right of the screen still shows connected I had an error message in the last event in it said that might DHCP settings were out of range. I get my internet at my house through a wireless portable hotspot through my smart phone. But i haven't ever had any problems before and i only have this problem on this network. If i turn airplane mode on and reset my network card, the internet will come back to life but soon die. i don't experience this problem while on a different network or if i'm on WiFi.

I'm sure there's a good reason for this. Problem is, I just don't get it. Thanks!

• Drupal: Exposing a module's data to Views2 using its API

  - by Sepehr Lajevardi

  I'm forking the filefield_stats module to provide it with the ability of exposing data into the Views module via the API. The filefield_stats module db table schema is as follow: <?php function filefield_stats_schema() { $schema['filefield_stats'] = array( 'fields' => array( 'fid' => array('type' => 'int', 'unsigned' => TRUE, 'not null' => TRUE, 'description' => 'Primary Key: the {files}.fid'), 'vid' => array('type' => 'int', 'unsigned' => TRUE, 'not null' => TRUE, 'description' => 'Primary Key: the {node}.vid'), 'uid' => array('type' => 'int', 'unsigned' => TRUE, 'not null' => TRUE, 'description' => 'The {users}.uid of the downloader'), 'timestamp' => array('type' => 'int', 'unsigned' => TRUE, 'not null' => TRUE, 'description' => 'The timestamp of the download'), 'hostname' => array('type' => 'varchar', 'length' => 128, 'not null' => TRUE, 'default' => '', 'description' => 'The hostname downloading the file (usually IP)'), 'referer' => array('type' => 'text', 'not null' => FALSE, 'description' => 'Referer for the download'), ), 'indexes' => array('fid_vid' => array('fid', 'vid')), ); return $schema; } ?> Well, so I implemented the hook_views_api() in filefield_stats.module & added a filefield_stats.views.inc file in the module's root directory, here it is: <?php // $Id$ /** * @file * Provide the ability of exposing data to Views2, for filefield_stats module. */ function filefield_stats_views_data() { $data = array(); $data['filefield_stats']['table']['group'] = t('FilefieldStats'); // Referencing the {node_revisions} table. $data['filefield_stats']['table']['join'] = array( 'node_revisions' => array( 'left_field' => 'vid', 'field' => 'vid', ), /*'files' => array( 'left_field' => 'fid', 'field' => 'fid', ), 'users' => array( 'left_field' => 'uid', 'field' => 'uid', ),*/ ); // Introducing filefield_stats table fields to Views2. // vid: The node's revision ID which wrapped the downloaded file $data['filefield_stats']['vid'] = array( 'title' => t('Node revision ID'), 'help' => t('The node\'s revision ID which wrapped the downloaded file'), 'relationship' => array( 'base' => 'node_revisions', 'field' => 'vid', 'handler' => 'views_handler_relationship', 'label' => t('Node Revision Reference.'), ), ); // uid: The ID of the user who downloaded the file. $data['filefield_stats']['uid'] = array( 'title' => t('User ID'), 'help' => t('The ID of the user who downloaded the file.'), 'relationship' => array( 'base' => 'users', 'field' => 'uid', 'handler' => 'views_handler_relationship', 'label' => t('User Reference.'), ), ); // fid: The ID of the downloaded file. $data['filefield_stats']['fid'] = array( 'title' => t('File ID'), 'help' => t('The ID of the downloaded file.'), 'relationship' => array( 'base' => 'files', 'field' => 'fid', 'handler' => 'views_handler_relationship', 'label' => t('File Reference.'), ), ); // hostname: The hostname which the file has been downloaded from. $data['filefield_stats']['hostname'] = array( 'title' => t('The Hostname'), 'help' => t('The hostname which the file has been downloaded from.'), 'field' => array( 'handler' => 'views_handler_field', 'click sortable' => TRUE, ), 'sort' => array( 'handler' => 'views_handler_sort', ), 'filter' => array( 'handler' => 'views_handler_filter_string', ), 'argument' => array( 'handler' => 'views_handler_argument_string', ), ); // referer: The referer address which the file download link has been triggered from. $data['filefield_stats']['referer'] = array( 'title' => t('The Referer'), 'help' => t('The referer which the file download link has been triggered from.'), 'field' => array( 'handler' => 'views_handler_field', 'click sortable' => TRUE, ), 'sort' => array( 'handler' => 'views_handler_sort', ), 'filter' => array( 'handler' => 'views_handler_filter_string', ), 'argument' => array( 'handler' => 'views_handler_argument_string', ), ); // timestamp: The time of the download. $data['filefield_stats']['timestamp'] = array( 'title' => t('Download Time'), 'help' => t('The time of the download.'), 'field' => array( 'handler' => 'views_handler_field_date', 'click sortable' => TRUE, ), 'sort' => array( 'handler' => 'views_handler_sort_date', ), 'filter' => array( 'handler' => 'views_handler_filter_date', ), ); return $data; } // filefield_stats_views_data() ?> According to the Views2 documentations this should work as a minimum, I think. But it doesn't! Also there is no error of any kind, when I come through the views UI, there's nothing about filefield_stats data. Any idea?

• phonegap.js crashes android app

  - by peirix

  I'm having this weird problem, where including the phonegap.js file in my project causes the app to crash on both the android emulator and my phone. I got the latest file from GitHub, so I can't see why this isn't working. This happens even if I try to build the sample project that's included in the PhoneGap download...

• How to fix a Sticky Footer that works, but after a browser window is resized, the footer overlaps.

  - by UXdesigner

  Good day, I've been trying to build a perfect footer who sticks at the bottom of the browser window after it's content. And I got help here @ Stack Overflow previously. But after a while, and doing a few tests, found out that after the browser window is resized, and then I scroll down , the footer overlaps...it is causing me a big headache right now and I'd like to fix this so I can move on. I'm going to post the display.css right here: @charset "utf-8"; body, html { margin: 0; padding: 0; text-align: center; position: relative; min-height:100%; /* needed for footer positioning*/ height:100%; /* needed for footer positioning*/ } .spacer { clear: both; height: 0; margin: 0; padding: 0; font-size: 0.1em; } .spacer_left { clear: left; margin: 0 0 10px 0; padding: 0; font-size: 0.1em; } hr { height: 1px; margin: 20px 0 20px 0; border: 0; color: #ccc; background: #ccc; } #container { position:relative; /* needed for footer positioning*/ min-height: 100%;/* needed for footer positioning*/ height: auto !important;/* needed for footer positioning*/ height: 100%;/* needed for footer positioning*/ margin: 0 auto -30px;/* needed for footer positioning*/ width: 1160px; padding: 0; border: 1px solid #333; text-align: left; } #header { margin: 0; padding: 5px; height:70px; } #login { font-family: Arial; font-size: 15px; color:#FFF; text-align: right; width: 440px; margin: 2px; } #login .theInput { font-family: Arial; font-size: 14px; width: 110px; margin-right: 5px; } #login .theSubmit { font-family: Arial; font-size: 10px; background-color: #333333; color: #FFFFFF; margin-right: 5px; } h1#lineainvisible { width:1160px; height:4px; position:relative; margin-top:4px; visibility: inherit; font-family:Arial, Helvetica, sans-serif; font-size:12px; } ul#nav { width:100%; height:36px; display:block; background-color:#000; background-repeat:repeat-x; } #wrapthatbanner { display:block; float:left; width:100%; height:524px; margin-bottom:20px; } #content { margin: 0px 20px 30px 20px; /* needed for footer positioning*/ } .panelsreadmore { margin-right: 10px;
