• Problem in Apache CXF (Simple Frontend): 'Already connected'

  - by seanizer

  I am using apache CXF for the first time. I am trying to establish a connection based on the CXF simple front end (Configuration notes) technology. I can't really see what I've done wrong, but I am getting a weird error (see below). I have also posted this question to [email protected], but I haven't received a response yet. Perhaps someone here can help. The service bean that is wrapped here is a Spring / JPA service that does not know anything about the web, I want to use simple frontend to publish it as a web service without having to annotate it with Jax-ws etc. (This works in theory). Here's my configuration: Server: <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:simple="http://cxf.apache.org/simple" xmlns:soap="http://cxf.apache.org/bindings/soap" xmlns:context="http://www.springframework.org/schema/context" xmlns:cs="http://[www.mycompany.com]/coupon/service" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://cxf.apache.org/bindings/soap http://cxf.apache.org/schemas/configuration/soap.xsd http://cxf.apache.org/simple http://cxf.apache.org/schemas/simple.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd" default-autowire="byType" > <import resource="classpath:META-INF/cxf/cxf.xml" /> <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" /> <import resource="classpath:META-INF/cxf/cxf-extension-http.xml" /> <import resource="classpath:META-INF/cxf/cxf-extension-http-binding.xml" /> <import resource="classpath:META-INF/cxf/cxf-servlet.xml" /> <import resource="classpath*:persistenceContext.xml" /> <!—my service implementation --> <!-- serviceClass points to an interface --> <simple:server id="server" serviceBean="couponService" serviceClass="[com.mycompany].MyServiceInterface" bindingId="http://apache.org/cxf/binding/http" address="/${wsdl.path}" serviceName="cs:couponService" endpointName="cs:couponServicePort" > <simple:dataBinding> <bean class="org.apache.cxf.aegis.databinding.AegisDatabinding" /> </simple:dataBinding> <simple:binding> <soap:soapBinding version="1.2" mtomEnabled="true" /> </simple:binding> </simple:server> <context:property-placeholder location="classpath:service.properties" /> </beans> Client: <beans xmlns="http://www.springframework.org/schema/beans" xmlns:simple="http://cxf.apache.org/simple" xmlns:soap="http://cxf.apache.org/bindings/soap" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:oxm=http://www.springframework.org/schema/oxm xmlns:cs="http://[www.mycompany.com]/coupon/service" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://cxf.apache.org/bindings/soap http://cxf.apache.org/schemas/configuration/soap.xsd http://cxf.apache.org/simple http://cxf.apache.org/schemas/simple.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/oxm http://www.springframework.org/schema/oxm/spring-oxm-3.0.xsd" default-autowire="byType" > <import resource="classpath:META-INF/cxf/cxf.xml" /> <import resource="classpath:META-INF/cxf/cxf-extension-http.xml" /> <import resource="classpath:META-INF/cxf/cxf-extension-http-binding.xml" /> <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" /> <simple:client id="couponService" wsdlLocation="${wsdl.url}?wsdl" serviceName="cs:couponService" endpointName="cs:couponServicePort" transportId="http://schemas.xmlsoap.org/soap/http" address="${wsdl.url}" bindingId="http://apache.org/cxf/binding/http" serviceClass="[com.mycompany].MyServiceInterface"> <simple:dataBinding> <bean class="org.apache.cxf.aegis.databinding.AegisDatabinding" /> </simple:dataBinding> <simple:binding> <soap:soapBinding mtomEnabled="true" version="1.2" /> </simple:binding> </simple:client> <context:property-placeholder location="classpath:service.properties" /> On the client side, I inject the generated service into my web application (I am using wicket but that should be irrelevant) and when I call service methods on it I get an IllegalStateException from java.net.HttpURLConnection saying the connection is already open.

I have searched the web for similar problems, but all I found was a bug using rest that has already been fixed. I am trying to use the simple frontend, as my service is not annotated with jax-ws annotations and I would like to keep it that way. Can someone help? Thanks in advance. Sean

• Could not synchronize database state with session

  - by user359427

  Hello all, I'm having trouble trying to persist an entity which ID is a generated value. This entity (A), at persistence time, has to persist in cascade another entity(B). The relationship within A and B is OneToMany, and the property related in B is part of a composite key. I'm using Eclipse, JBOSS Runtime, JPA/Hibernate Here is my code: Entity A: @Entity public class Cambios implements Serializable { private static final long serialVersionUID = 1L; @SequenceGenerator(name="CAMBIOS_GEN",sequenceName="CAMBIOS_SEQ",allocationSize=1) @Id @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="CAMBIOS_GEN") @Column(name="ID_CAMBIO") private Long idCambio; //bi-directional many-to-one association to ObjetosCambio @OneToMany(cascade={CascadeType.PERSIST},mappedBy="cambios") private List<ObjetosCambio> objetosCambioList; public Cambios() { } ... } Entity B: @Entity @Table(name="OBJETOS_CAMBIO") public class ObjetosCambio implements Serializable { private static final long serialVersionUID = 1L; @EmbeddedId private ObjetosCambioPK id; //bi-directional many-to-one association to Cambios @ManyToOne @JoinColumn(name="ID_CAMBIO", insertable=false, updatable=false) private Cambios cambios; //bi-directional many-to-one association to Objetos @ManyToOne @JoinColumn(name="ID_OBJETO", insertable=false, updatable=false) private Objetos objetos; public ObjetosCambio() { } ...

• Java, server client TCP communication ends with RST

  - by Senne

  I'm trying to figure out if this is normal. Because without errors, a connection should be terminated by: FIN -> <- ACK <- FIN ACK -> I get this at the end of a TCP connection (over SSL, but i also get it with non-encrypted): From To 1494 server client TCP search-agent > 59185 [PSH, ACK] Seq=25974 Ack=49460 Win=63784 Len=50 1495 client server TCP 59185 > search-agent [ACK] Seq=49460 Ack=26024 Win=63565 Len=0 1496 client server TCP 59185 > search-agent [PSH, ACK] Seq=49460 Ack=26024 Win=63565 Len=23 1497 client server TCP 59185 > search-agent [FIN, ACK] Seq=49483 Ack=26024 Win=63565 Len=0 1498 server client TCP search-agent > 59185 [PSH, ACK] Seq=26024 Ack=49484 Win=63784 Len=23 1499 client server TCP 59185 > search-agent [RST, ACK] Seq=49484 Ack=26047 Win=0 Len=0 The client exits normally and reaches socket.close, shouldn't then the connection be shut down normally, without a reset?

• selectOneMenu - java.lang.NullPointerException when adding record to the database (JSF2 and JPA2-OpenJPA)

  - by rogie

  Good day to all; I'm developing a program using JSF2 and JPA2 (OpenJPA). Im also using IBM Rapid App Dev't v8 with WebSphere App Server v8 test server. I have two simple entities, Employee and Department. Each Department has many Employees and each Employee belongs to a Department (using deptno and workdept). My problem occurs when i tried to add a new employee and selecting a department from a combo box (using selectOneMenu - populated from Department table): when i run the program, the following error messages appeared: An Error Occurred: java.lang.NullPointerException Caused by: java.lang.NullPointerException - java.lang.NullPointerException I also tried to make another program using Deptno and Workdept as String instead of integer, still doesn't work. Pls help. Im also a newbie. Tnx and God bless. Below are my codes, configurations and setup. Just tell me if there are some codes that I forgot to include. Im also using Derby v10.5 as my database: CREATE SCHEMA RTS; CREATE TABLE RTS.DEPARTMENT (DEPTNO INTEGER NOT NULL GENERATED ALWAYS AS IDENTITY (START WITH 1, INCREMENT BY 1), DEPTNAME VARCHAR(30)); ALTER TABLE RTS.DEPARTMENT ADD CONSTRAINT PK_DEPARTMNET PRIMARY KEY (DEPTNO);

  Hi In my Struts2 applicaion I have a Jsp page with some feilds , like this <s:form action="customer.action" method="post" validate="false"> <s:textfield name="cust.fname" key="fname" size="20" /> <s:textfield name="cust.lname" key="lname" size="20" /> <s:textfield name="cust.title" key="title" size="20" /> <s:submit method="addCustomer" key="label.submit" align="center" /> </s:form> I have created a Bean Class For that public class Customer { private String fname; private String lname; private String title; public String getFname() { return fname; } public void setFname(String fname) { this.fname = fname; } public String getLname() { return lname; } public void setLname(String lname) { this.lname = lname; } public String getAddress() { return address; } public void setAddress(String address) { this.address = address; } } an Action Class public class CustomerAction extends ActionSupport { private Customer cust; public Customer getCust() { return cust; } public void setCust(Customer cust) { this.cust = cust; } public String addCustomer() { return "success"; } } When i hit the submit button i m getting exception like this

• Flex Canvas child Randomly resizes

  - by BS_C3

  Hi! I have an application with a viewstack that contains all the components that need to be displayed. The navigation is defined in the main application. All the components are based on canvas. The main application looks like that: <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" xmlns:components="components.*"> <mx:VBox width="1024" height="100%" horizontalCenter="0" verticalGap="0" backgroundColor="#FFFFFF"> <mx:Image id="header" verticalAlign="top" /> <mx:ViewStack id="body" horizontalCenter="0" verticalCenter="0" width="100%" height="100%"> <components:HomePage id="hp" width="100%"/> <components:CollectionSelection id="cs" width="100%"/> <components:SearchEngine id="se" width="100%"/> <components:SearchResult id="sr" width="100%"/> <components:Tray id="tr" width="100%"/> <components:Order id="or" width="100%"/> </mx:ViewStack> <mx:Image id="footer" verticalAlign="bottom" maintainAspectRatio="false" width="100%"/> </mx:VBox> </mx:Application> I'm getting a strange behaviour from the TRAY component. Here's the code for component Tray (I've only left the display info): <mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml"> <mx:Image id="bg" horizontalCenter="0" verticalCenter="0" width="100%" height="100%" maintainAspectRatio="false"/> <mx:HBox width="100%"> <mx:Button x="20" y="20" label="BACK"/> <mx:Spacer width="100%"/> <mx:LinkBar itemClick="linkbar_itemClick(event)" styleName="GLBLinkBTN" separatorColor="#FFFFFF" separatorWidth="1" > <mx:dataProvider> <mx:Object label="CLEAR"/> <mx:Object label="LOGOUT"/> </mx:dataProvider> </mx:LinkBar> </mx:HBox> <mx:VBox id="mainBox" horizontalCenter="0" verticalCenter="0" verticalGap="0"> <mx:HBox width="100%" height="50" backgroundColor="#60524D" verticalAlign="bottom" paddingBottom="5"> <mx:Label styleName="TRTitle" paddingLeft="15"/> <mx:Spacer width="100%"/> <mx:Label styleName="TRItems" paddingRight="15"/> </mx:HBox> <mx:HorizontalList id="hlist" dataProvider="{TrayData.instance.itemsCollection}" columnCount="{TrayData.instance.hlistColumns}" rowCount="1" itemRenderer="components.TrayItem" horizontalScrollPolicy="off" rollOverColor="#FFFFFF" selectionColor="#FFFFFF" horizontalCenter="0" verticalCenter="0" borderStyle="none" horizontalScrollPosition="{TrayData.instance.hsPosition}" /> <mx:HBox width="100%" backgroundColor="#E7DDDB" height="40" verticalAlign="middle" paddingLeft="20" paddingRight="20"> <mx:Box width="25" verticalAlign="middle" horizontalAlign="left"> <mx:Button id="leftBtn" /> </mx:Box> <mx:Spacer width="100%"/> <mx:Box width="25" verticalAlign="middle" horizontalAlign="right"> <mx:Button id="rightBtn" /> </mx:Box> </mx:HBox> </mx:VBox> </mx:Canvas> All the components are displaying properly. However, sometimes, randomly, the vbox "mainBox" in the tray component is not displaying as it should: the horizontallist shrinks and instead of fully displaying its items, I get horizontal and vertical scrollbars for each item... I'm currently trying to reproduce this behaviour (to get a print screen) but right know, it's working fine... -_-' As soon as I get it work as it shouldn't, I'll upload an image. Here's the code for the itemRenderer (just in case...): <mx:VBox xmlns:mx="http://www.adobe.com/2006/mxml" > <mx:HBox width="100%" paddingTop="0" paddingBottom="0" paddingRight="3"> <mx:Spacer width="100%"/> <mx:Box width="14" height="14" verticalAlign="middle" horizontalAlign="center"> <mx:Button width="8" height="8"/> </mx:Box> </mx:HBox> <mx:VBox paddingLeft="20" paddingRight="20" verticalGap="15" paddingBottom="15"> <mx:Canvas id="thumbnail"> <mx:Image id="thumbnailBG" /> <mx:Image id="thumbnailIM" /> </mx:Canvas > <mx:VBox width="100%" verticalGap="7"> <mx:HBox width="100%" height="13"> <mx:Label width="74" opaqueBackground="#ECE5E2"/> <mx:Label paddingBottom="5"/> </mx:HBox> <mx:HBox width="100%" height="13"> <mx:Label width="74" opaqueBackground="#ECE5E2"/> <mx:Label /> </mx:HBox> <mx:HBox width="100%" height="13"> <mx:Label width="74" opaqueBackground="#ECE5E2"/> <mx:Label /> </mx:HBox> <mx:HBox width="100%" height="13"> <mx:Label width="74"opaqueBackground="#ECE5E2"/> <mx:Label /> </mx:HBox> <mx:HBox width="100%" height="13"> <mx:Label width="74" opaqueBackground="#ECE5E2"/> <mx:Label /> </mx:HBox> <mx:HBox width="100%" height="13"> <mx:Label width="74" opaqueBackground="#ECE5E2"/> <mx:Label /> </mx:HBox> <mx:HBox width="100%" height="13"> <mx:Label width="74" opaqueBackground="#ECE5E2"/> <mx:Label /> </mx:HBox> <mx:HBox width="100%" height="13"> <mx:Label width="74" opaqueBackground="#ECE5E2"/> <mx:Label /> </mx:HBox> </mx:VBox> <mx:Button /> </mx:VBox> </mx:VBox> Your help would really be appreciated.

  I have in Java two panels which need to have same layout, there is my functions for initializations panels. private void InitializePanelCom(){ pnlCom=new JPanel(); pnlCom.setSize(300,160); pnlCom.setLocation(10, 60); add(pnlCom); GridBagLayout gb=new GridBagLayout(); GridBagConstraints gc=new GridBagConstraints(); pnlCom.setLayout(gb); jLabelcommPort = setJLabel("Com Port : "); jLabelbaudRate = setJLabel("Baud Rate : "); jLabelplcAddress = setJLabel("Plc Address : "); jLabelsendTime = setJLabel("Send Time : "); jLabelx50 = setJLabel(" x 50 ms (2 - 99)"); jComboBoxcommPort = setJComboBox(commPortList); jComboBoxbaudRate = setJComboBox(bitRateList); jTextAreaPlcAddress = setJTextField(""); jTextAreaSendTime = setJTextField(""); gc.insets = new Insets(10,0,0,0); gc.ipadx = 120; gc.weightx = 1; gc.gridx = 0; gc.gridy = 0; gc.anchor=GridBagConstraints.EAST; pnlCom.add(jLabelcommPort,gc); gc.insets = new Insets(10,0,0,0); gc.ipadx = 120; gc.weightx = 1; gc.gridx = 1; gc.gridy = 0; gc.anchor=GridBagConstraints.EAST; pnlCom.add(jComboBoxcommPort,gc); gc.insets=new Insets(10,0,0,0); gc.ipadx=120; gc.weightx=1; gc.gridx=0; gc.gridy=1; gc.anchor=GridBagConstraints.EAST; pnlCom.add(jLabelbaudRate,gc); gc.insets=new Insets(10,0,0,0); gc.ipadx=120; gc.weightx=1; gc.gridx=1; gc.gridy=1; gc.anchor=GridBagConstraints.EAST; pnlCom.add(jComboBoxbaudRate,gc); gc.insets=new Insets(10,0,0,0); gc.ipadx=120; gc.weightx=1; gc.gridx=0; gc.gridy=2; gc.anchor=GridBagConstraints.EAST; pnlCom.add(jLabelplcAddress,gc); gc.insets=new Insets(10,0,0,0); gc.ipadx=120; gc.weightx=1; gc.gridx=1; gc.gridy=2; gc.anchor=GridBagConstraints.EAST; pnlCom.add(jTextAreaPlcAddress,gc); gc.insets=new Insets(10,0,0,0); gc.ipadx=120; gc.weightx=1; gc.gridx=0; gc.gridy=3; gc.anchor=GridBagConstraints.EAST; pnlCom.add(jLabelsendTime,gc); gc.insets=new Insets(10,0,0,0); gc.ipadx=120; gc.weightx=1; gc.gridx=1; gc.gridy=3; gc.anchor=GridBagConstraints.EAST; pnlCom.add(jTextAreaSendTime,gc); gc.insets=new Insets(10,0,0,0); gc.ipadx=120; gc.weightx=1; gc.gridx=2; gc.gridy=3; gc.anchor=GridBagConstraints.EAST; pnlCom.add(jLabelx50,gc); } ![alt text][1] private void InitializePanelTcp(){ pnlTcp=new JPanel(); pnlTcp.setSize(300,160); pnlTcp.setLocation(10, 60); add(pnlTcp); GridBagLayout gb=new GridBagLayout(); GridBagConstraints gc=new GridBagConstraints(); pnlTcp.setLayout(gb); lblIPAddress=setJLabel("IP Address : "); txtIPAddress=setJTextField(""); lblPort=setJLabel("Port : "); txtPort=setJTextField(""); cmbBaudRateTCP = setJComboBox(bitRateList); lblBaudRateTCP = setJLabel("Baud Rate : "); lblParityCheck=setJLabel("Parity check : "); txtParityCheck=setJTextField(""); gc.insets = new Insets(10,0,0,0); //gc.ipadx = 20; gc.weightx = 0.3; gc.gridx = 0; gc.gridy = 0; gc.anchor=GridBagConstraints.WEST; pnlTcp.add(lblIPAddress,gc); gc.insets = new Insets(10,0,0,0); //gc.ipadx = 80; gc.weightx = 0.7; gc.gridx = 1; gc.gridy = 0; gc.anchor=GridBagConstraints.WEST; pnlTcp.add(txtIPAddress,gc); gc.insets=new Insets(10,0,0,0); //gc.ipadx=120; gc.weightx=0.3; gc.gridx=0; gc.gridy=1; gc.anchor=GridBagConstraints.WEST; pnlTcp.add(lblPort,gc); gc.insets=new Insets(10,0,0,0); //gc.ipadx=80; gc.weightx=0.7; gc.gridx=1; gc.gridy=1; gc.anchor=GridBagConstraints.WEST; pnlTcp.add(txtPort,gc); gc.insets=new Insets(10,0,0,0); //gc.ipadx=120; gc.weightx=0.3; gc.gridx=0; gc.gridy=2; gc.anchor=GridBagConstraints.WEST; pnlTcp.add(lblBaudRateTCP,gc); gc.insets=new Insets(10,0,0,0); //gc.ipadx=0; gc.weightx=0.7; gc.gridx=1; gc.gridy=2; gc.anchor=GridBagConstraints.WEST; pnlTcp.add(cmbBaudRateTCP,gc); gc.insets=new Insets(10,0,0,0); //gc.ipadx=120; gc.weightx=0.3; gc.gridx=0; gc.gridy=3; gc.anchor=GridBagConstraints.WEST; pnlTcp.add(lblParityCheck,gc); gc.insets=new Insets(10,0,0,0); //gc.ipadx=0; gc.weightx=1.7; gc.gridx=1; gc.gridy=3; gc.anchor=GridBagConstraints.WEST; pnlTcp.add(txtParityCheck,gc); } Problem is that second panel (initializetcp, second picture doesn't look the same, labels are moved at left , it is different ). Can anybody help, I am new with GridBagContsraints at all ?

• NetLogo 4.1 - implementation of a motorway ( Problem creating collision of cars )

  - by user206019

  Hi there, I am trying to create a simulation of motorway and the behaviour of the drivers in NetLogo. I have some questions that I m struggling to solve. Here is my code: globals [ selected-car ;; the currently selected car average-speed ;; average speed of all the cars look-ahead ] turtles-own [ speed ;; the current speed of the car speed-limit ;; the maximum speed of the car (different for all cars) lane ;; the current lane of the car target-lane ;; the desired lane of the car change? ;; true if the car wants to change lanes patience ;; the driver's current patience max-patience ;; the driver's maximum patience ] to setup ca import-drawing "my_road3.png" set-default-shape turtles "car" crt number_of_cars [ setup-cars ] end to setup-cars set color blue set size .9 set lane (random 3) set target-lane (lane + 1) setxy round random-xcor (lane + 1) set heading 90 set speed 0.1 + random 9.9 set speed-limit (((random 11) / 10) + 1) set change? false set max-patience ((random 50) + 10) set patience (max-patience - (random 10)) ;; make sure no two cars are on the same patch loop [ ifelse any? other turtles-here [ fd 1 ] [ stop ] ;if count turtles-here > 1 ; fd 0.1 ;if ; ;ifelse (any? turtles-on neighbors) or (count turtles-here > 1) ;[ ; ifelse (count turtles-here = 1) ; [ if any? turtles-on neighbors ; [ ; if distance min-one-of turtles-on neighbors [distance myself] > 0.9 ; [stop] ; ] ; ] ; [ fd 0.1 ] ;] ;[ stop ] ] end to go drive end to drive ;; first determine average speed of the cars set average-speed ((sum [speed] of turtles) / number_of_cars) ;set-current-plot "Car Speeds" ;set-current-plot-pen "average" ;plot average-speed ;set-current-plot-pen "max" ;plot (max [speed] of turtles) ;set-current-plot-pen "min" ;plot (abs (min [speed] of turtles) ) ;set-current-plot-pen "selected-car" ;plot ([speed] of selected-car) ask turtles [ ifelse (any? turtles-at 1 0) [ set speed ([speed] of (one-of (turtles-at 1 0))) decelerate ] [ ifelse (look-ahead = 2) [ ifelse (any? turtles-at 2 0) [ set speed ([speed] of (one-of turtles-at 2 0)) decelerate ] [ accelerate if count turtles-at 0 1 = 0 and ycor < 2.5 [lt 90 fd 1 rt 90] ] ] [accelerate if count turtles-at 0 1 = 0 and ycor < 2.5 [lt 90 fd 1 rt 90] ] ] if (speed < 0.01) [ set speed 0.01 ] if (speed > speed-limit) [ set speed speed-limit ] ifelse (change? = false) [ signal ] [ change-lanes ] ;; Control for making sure no one crashes. ifelse (any? turtles-at 1 0) and (xcor != min-pxcor - .5) [ set speed [speed] of (one-of turtles-at 1 0) ] [ ifelse ((any? turtles-at 2 0) and (speed > 1.0)) [ set speed ([speed] of (one-of turtles-at 2 0)) fd 1 ] [jump speed] ] ] tick end ;; increase speed of cars to accelerate ;; turtle procedure set speed (speed + (speed-up / 1000)) end ;; reduce speed of cars to decelerate ;; turtle procedure set speed (speed - (slow-down / 1000)) end to signal ifelse (any? turtles-at 1 0) [ if ([speed] of (one-of (turtles-at 1 0))) < (speed) [ set change? true ] ] [ set change? false ] end ;; undergoes search algorithms to change-lanes ;; turtle procedure show ycor ifelse (patience <= 0) [ ifelse (max-patience <= 1) [ set max-patience (random 10) + 1 ] [ set max-patience (max-patience - (random 5)) ] set patience max-patience ifelse (target-lane = 0) [ set target-lane 1 set lane 0 ] [ set target-lane 0 set lane 1 ] ] [ set patience (patience - 1) ] ifelse (target-lane = lane) [ ifelse (target-lane = 0) [ set target-lane 1 set change? false ] [ set target-lane 0 set change? false ] ] [ ifelse (target-lane = 1) [ ifelse (pycor = 2) [ set lane 1 set change? false ] [ ifelse (not any? turtles-at 0 1) [ set ycor (ycor + 1) ] [ ifelse (not any? turtles-at 1 0) [ set xcor (xcor + 1) ] [ decelerate if (speed <= 0) [ set speed 0.1 ] ] ] ] ] [ ifelse (pycor = -2) [ set lane 0 set change? false ] [ ifelse (not any? turtles-at 0 -1) [ set ycor (ycor - 1) ] [ ifelse (not any? turtles-at 1 0) [ set xcor (xcor + 1) ] [ decelerate if (speed <= 0) [ set speed 0.1 ] ] ] ] ] ] end I know its a bit messy because I am using code from other models from the library. I want to know how to create the collision of the cars. I can't think of any idea. As you notice my agent has almost the same size as the patch (I set it to 0.9 so that you can distinguish the space between 2 cars when they are set next to each other and I round the coordinates so that they are set to the centre of the patch). In my accelerate procedure I set my agent to turn left, move 1, turn right in a loop. I want to know if there's a command that lets me make the agent jump from one lane to the other (to the patch next to it on its left) without making it turn and move. And last, if you notice the code i created the car checks the patch that is next to it on the lane on its left and the patch in front of it and the back of it. So if the 3 patches on its left are empty then it can change lane. The fuzzy part is that when i run the setup and I press Go sometimes (not always) the car goes out of the 3 basic lanes. To understand this I have 7 lanes. The middle one which I don't use which is lane 0. Then there are 3 lanes on top of lane 0 and 3 below it. So the code I am using refers to the upper 3 lanes where I set the cars but for some reason some of the cars change lane and go to lane -3 then -2 and so forth. If someone can give me a tip I would really appreciate it. Thank you in advance. Tip: if you want to try this code in netlogo keep in mind that on interface tab I have 2 buttons one setup and one go as well as 3 sliders with names: number_of_cars , speed-up , slow-down.

• Passing XML markers to Google Map

  - by djmadscribbler

  I've been creating a V3 Google map based on this example from Mike Williams http://www.geocodezip.com/v3_MW_example_map3.html I've run into a bit of a problem though. If I have no parameters in my URL then I get the error "id is undefined idmarkers [id.toLowerCase()] = marker;" in Firebug and only one marker will show up. If I have a parameter (?id=105 for example) then all the sidebar links say 105 (or whatever the parameter in the URL was) instead of their respective label as listed in the XML file and a random infowindow will be opened instead of the window for the id in the URL. Here is my javascript: var map = null; var lastmarker = null; // ========== Read paramaters that have been passed in ========== // Before we go looking for the passed parameters, set some defaults // in case there are no parameters var id; var index = -1; // these set the initial center, zoom and maptype for the map // if it is not specified in the query string var lat = 42.194741; var lng = -121.700301; var zoom = 18; var maptype = google.maps.MapTypeId.HYBRID;

break; default: case google.maps.MapTypeId.ROADMAP: urlValue = 'm'; break; } return urlValue; } // If there are any parameters at eh end of the URL, they will be in location.search // looking something like "?marker=3" // skip the first character, we are not interested in the "?" var query = location.search.substring(1); // split the rest at each "&" character to give a list of "argname=value" pairs var pairs = query.split("&"); for (var i = 0; i < pairs.length; i++) { // break each pair at the first "=" to obtain the argname and value var pos = pairs[i].indexOf("="); var argname = pairs[i].substring(0, pos).toLowerCase(); var value = pairs[i].substring(pos + 1).toLowerCase(); // process each possible argname - use unescape() if theres any chance of spaces if (argname == "id") { id = unescape(value);

• PE Header Requirements

  - by Pindatjuh

  What are the requirements of a PE file (PE/COFF)? What fields should be set, which value, at a bare minimum for enabling it to "run" on Windows (i.e. executing "ret" instruction and then close, without error). The library I am building first is the linker: Now, the problem I have is the PE file (PE/COFF). I don't know what is "required" for a PE file before it can actually execute on my platform. My testing platform is Vista. I get an error message, saying "This is not a valid Win32 executable." when I execute it by double-clicking, and I get an "Access Denied." when executing it with CLI cmd. I have two sections, .text and .data. I've implemented the PE headers as provided by several online documents, i.e. MSDN and some other thirdparty documentation. If I use a hex-editor, it looks almost like a regular PE file. I don't use any imports, nor IAT, nor any directories in the PE header. Edit: I've added an import table, still not a valid .exe-file, says my Windows. I've tried to use values which are also mentioned at the smallest PE-file guide. No luck. Really the only thing I can't seem to figure out is what is required and what isn't. Some guides tell me everything is required, whilst others say about deprications: and it can be zero. I hope this is enough information. Thank you, in advance.

• doubt regarding carrying data in custom events using actionscript

  - by user267530

  Hi I am working on actionscript to generate a SWF dynamically using JSON data coming from an HTTP request. I receive the data on creationComplete and try to generate a tree like structure. I don’t create the whole tree at the same time. I create 2 levels, level 1 and level 2. My goal is to attach custom events on the panels which represent tree nodes. When users click the panels, it dispatches custom events and try to generate the next level. So, it goes like this : On creation complete - get JSON- create top tow levels - click on level 2- create the level 2 and level 3 - click on level 3- create level 3 and 4. …and so on and so on. I am attaching my code with this email. Please take a look at it and if you have any hints on how you would do this if you need to paint a tree having total level number = “n” where( 0 import com.iwobanas.effects.*; import flash.events.MouseEvent; import flash.filters.BitmapFilterQuality; import flash.filters.BitmapFilterType; import flash.filters.GradientGlowFilter; import mx.controls.Alert; private var roundedMask:Sprite; private var panel:NewPanel; public var oldPanelIds:Array = new Array(); public var pages:Array = new Array();//cleanup public var delPages:Array = new Array(); public function DrawPlaybook(pos:Number,title:String,chld:Object):void { panel = new NewPanel(chld); panel.title = title; panel.name=title; panel.width = 100; panel.height = 80; panel.x=pos+5; panel.y=40; // Define a gradient glow. var gradientGlow:GradientGlowFilter = new GradientGlowFilter(); gradientGlow.distance = 0; gradientGlow.angle = 45; gradientGlow.colors = [0xFFFFF0, 0xFFFFFF]; gradientGlow.alphas = [0, 1]; gradientGlow.ratios = [0, 255]; gradientGlow.blurX = 10; gradientGlow.blurY = 10; gradientGlow.strength = 2; gradientGlow.quality = BitmapFilterQuality.HIGH; gradientGlow.type = BitmapFilterType.OUTER; panel.filters =[gradientGlow]; this.rawChildren.addChild(panel); pages.push(panel); panel.addEventListener(MouseEvent.CLICK, function(e:MouseEvent){onClickHandler(e,title,chld)}); this.addEventListener(CustomPageClickEvent.PANEL_CLICKED, function(e:CustomPageClickEvent){onCustomPanelClicked(e,title)}); } public function onClickHandler(e:MouseEvent,title:String,chld:Object):void { //var panel:Panel; for each(var stp1:NewPanel in pages){ if(stp1.title==title){ var eventObj:CustomPageClickEvent = new CustomPageClickEvent("panelClicked"); eventObj.panelClicked = stp1; dispatchEvent(eventObj); } } } private function onCustomPanelClicked(e:CustomPageClickEvent,title:String):void { //cleanup itself Alert.show("onCustomPanelClicked" + title); var panel:NewPanel; for each(var stp:NewPanel in pages){ startAnimation(e,stp); } if(title == e.panelClicked.title){ panel = new NewPanel(null); panel.title = title; panel.name=title; panel.width = 150; panel.height = 80; panel.x=100; panel.y=40; this.rawChildren.addChild(panel); // var slideRight:SlideRight = new SlideRight(); slideRight.target=panel; slideRight.duration=750; slideRight.showTarget=true; slideRight.play(); //draw the steps var jsonData = this.map.getValue(title); var posX:Number = 50; var posY:Number = 175; for each ( var pnl:NewPanel in pages){ pages.pop(); } for each ( var stp1:Object in jsonData.children){ //Alert.show("map step=" + stp.text ); panel = new NewPanel(null); panel.title = stp1.text; panel.name=stp1.id; panel.width = 100; panel.id=stp1.id; panel.height = 80; panel.x = posX; panel.y=posY; posX+=150; var s:String="hi" + stp1.text; panel.addEventListener(MouseEvent.CLICK, function(e:MouseEvent){onChildClick(e,s);}); this.addEventListener(CustomPageClickEvent.PANEL_CLICKED, function(e:CustomPageClickEvent){onCustomPnlClicked(e)}); this.rawChildren.addChild(panel); // Alert.show("map step=" + this.getChildIndex(panel) ); // oldPanelIds.push(panel); pages.push(panel); //this.addEventListener(CustomPageClickEvent.PANEL_CLICKED, //function(e:CustomPageClickEvent){onCustomPanelClicked(e,title)}); var slide:SlideUp = new SlideUp(); slide.target=panel; slide.duration=1500; slide.showTarget=false; slide.play(); } } } public function onChildClick(e:MouseEvent,s:String):void { //var panel:Panel; //Alert.show(e.currentTarget.title); for each(var stp1:NewPanel in pages){ if(stp1.title==e.currentTarget.title){ var eventObj:CustomPageClickEvent = new CustomPageClickEvent("panelClicked"); eventObj.panelClicked = stp1; dispatchEvent(eventObj); } } } private function onCustomPnlClicked(e:CustomPageClickEvent):void { for each ( var pnl:NewPanel in pages){ pages.pop(); } //onCustomPanelClicked(e,e.currentTarget.title); //Alert.show("hi from cstm" + e.panelClicked.title); } private function fadePanel(event:Event,panel:NewPanel):void{ panel.alpha -= .005; if (panel.alpha <= 0){ //Alert.show(panel.title); panel.removeEventListener(Event.ENTER_FRAME, function(e:Event){fadePanel(e,panel);}); }; panel.title=""; } private function startAnimation(event:CustomPageClickEvent,panel:NewPanel):void{ panel.addEventListener(Event.ENTER_FRAME, function(e:Event){fadePanel(e,panel)}); } Thanks in advance.

• Autocorrelation returns random results with mic input (using a high pass filter)

  - by Niall

  Hello, Sorry to ask a similar question to the one i asked before (FFT Problem (Returns random results)), but i've looked up pitch detection and autocorrelation and have found some code for pitch detection using autocorrelation. Im trying to do pitch detection of a users singing. Problem is, it keeps returning random results. I've got some code from http://code.google.com/p/yaalp/ which i've converted to C++ and modified (below). My sample rate is 2048, and data size is 1024. I'm detecting pitch of both a sine wave and mic input. The frequency of the sine wave is 726.0, and its detecting it to be 722.950820 (which im ok with), but its detecting the pitch of the mic as a random number from around 100 to around 1050. I'm now using a High pass filter to remove the DC offset, but it's not working. Am i doing it right, and if so, what else can i do to fix it? Any help would be greatly appreciated! double* doHighPassFilter(short *buffer) { // Do FFT: int bufferLength = 1024; float *real = malloc(bufferLength*sizeof(float)); float *real2 = malloc(bufferLength*sizeof(float)); for(int x=0;x<bufferLength;x++) { real[x] = buffer[x]; } fft(real, bufferLength); for(int x=0;x<bufferLength;x+=2) { real2[x] = real[x]; } for (int i=0; i < 30; i++) //Set freqs lower than 30hz to zero to attenuate the low frequencies real2[i] = 0; // Do inverse FFT: inversefft(real2,bufferLength); double* real3 = (double*)real2; return real3; } double DetectPitch(short* data) { int sampleRate = 2048; //Create sine wave double *buffer = malloc(1024*sizeof(short)); double amplitude = 0.25 * 32768; //0.25 * max length of short double frequency = 726.0; for (int n = 0; n < 1024; n++) { buffer[n] = (short)(amplitude * sin((2 * 3.14159265 * n * frequency) / sampleRate)); } doHighPassFilter(data); printf("Pitch from sine wave: %f\n",detectPitchCalculation(buffer, 50.0, 1000.0, 1, 1)); printf("Pitch from mic: %f\n",detectPitchCalculation(data, 50.0, 1000.0, 1, 1)); return 0; } // These work by shifting the signal until it seems to correlate with itself. // In other words if the signal looks very similar to (signal shifted 200 data) than the fundamental period is probably 200 data // Note that the algorithm only works well when there's only one prominent fundamental. // This could be optimized by looking at the rate of change to determine a maximum without testing all periods. double detectPitchCalculation(double* data, double minHz, double maxHz, int nCandidates, int nResolution) { //-------------------------1-------------------------// // note that higher frequency means lower period int nLowPeriodInSamples = hzToPeriodInSamples(maxHz, 2048); int nHiPeriodInSamples = hzToPeriodInSamples(minHz, 2048); if (nHiPeriodInSamples <= nLowPeriodInSamples) printf("Bad range for pitch detection."); if (1024 < nHiPeriodInSamples) printf("Not enough data."); double *results = new double[nHiPeriodInSamples - nLowPeriodInSamples]; //-------------------------2-------------------------// for (int period = nLowPeriodInSamples; period < nHiPeriodInSamples; period += nResolution) { double sum = 0; // for each sample, find correlation.

Returns the indices of the best parts. /// (One way to do this would be to sort the array, but that could take too long. /// Warning: Changes the contents of the array!!! Do not use result array afterwards. int* findBestCandidates(int n, double* inputs,int length) { //int length = inputs.Length; if (length < n) printf("Length of inputs is not long enough."); int *res = new int[n]; double minValue = 0; for (int c = 0; c < n; c++) { // find the highest. double fBestValue = minValue; int nBestIndex = -1; for (int i = 0; i < length; i++) { if (inputs[i] > fBestValue) { nBestIndex = i; fBestValue = inputs[i]; } } // record this highest value res[c] = nBestIndex; // now blank out that index. if(nBestIndex!=-1) inputs[nBestIndex] = minValue; } return res; } int hzToPeriodInSamples(double hz, int sampleRate) { return (int)(1 / (hz / (double)sampleRate)); } double periodInSamplesToHz(int period, int sampleRate) { return 1 / (period / (double)sampleRate); } Thanks, Niall. Edit: Changed the code to implement a high pass filter with a cutoff of 30hz (from What Are High-Pass and Low-Pass Filters?, can anyone tell me how to convert the low-pass filter using convolution to a high-pass one?) but it's still returning random results. Plugging it into a VST host and using VST plugins to compare spectrums isn't an option to me unfortunately.

• How do I get .NET to garbage collect aggressively?

  - by mmr

  I have an application that is used in image processing, and I find myself typically allocating arrays in the 4000x4000 ushort size, as well as the occasional float and the like. Currently, the .NET framework tends to crash in this app apparently randomly, almost always with an out of memory error. 32mb is not a huge declaration, but if .NET is fragmenting memory, then it's very possible that such large continuous allocations aren't behaving as expected. Is there a way to tell the garbage collector to be more aggressive, or to defrag memory (if that's the problem)? I realize that there's the GC.Collect and GC.WaitForPendingFinalizers calls, and I've sprinkled them pretty liberally through my code, but I'm still getting the errors. It may be because I'm calling dll routines that use native code a lot, but I'm not sure. I've gone over that C++ code, and make sure that any memory I declare I delete, but still I get these C# crashes, so I'm pretty sure it's not there. I wonder if the C++ calls could be interfering with the GC, making it leave behind memory because it once interacted with a native call-- is that possible? If so, can I turn that functionality off? EDIT: Here is some very specific code that will cause the crash. According to this SO question, I do not need to be disposing of the BitmapSource objects here. Here is the naive version, no GC.Collects in it. It generally crashes on iteration 4 to 10 of the undo procedure. This code replaces the constructor in a blank WPF project, since I'm using WPF. I do the wackiness with the bitmapsource because of the limitations I explained in my answer to @dthorpe below as well as the requirements listed in this SO question. public partial class Window1 : Window { public Window1() { InitializeComponent(); //Attempts to create an OOM crash //to do so, mimic minute croppings of an 'image' (ushort array), and then undoing the crops int theRows = 4000, currRows; int theColumns = 4000, currCols; int theMaxChange = 30; int i; List<ushort[]> theList = new List<ushort[]>();//the list of images in the undo/redo stack byte[] displayBuffer = null;//the buffer used as a bitmap source BitmapSource theSource = null; for (i = 0; i < theMaxChange; i++) { currRows = theRows - i; currCols = theColumns - i; theList.Add(new ushort[(theRows - i) * (theColumns - i)]); displayBuffer = new byte[theList[i].Length]; theSource = BitmapSource.Create(currCols, currRows, 96, 96, PixelFormats.Gray8, null, displayBuffer, (currCols * PixelFormats.Gray8.BitsPerPixel + 7) / 8); System.Console.WriteLine("Got to change " + i.ToString()); System.Threading.Thread.Sleep(100); } //should get here. If not, then theMaxChange is too large. //Now, go back up the undo stack. for (i = theMaxChange - 1; i >= 0; i--) { displayBuffer = new byte[theList[i].Length]; theSource = BitmapSource.Create((theColumns - i), (theRows - i), 96, 96, PixelFormats.Gray8, null, displayBuffer, ((theColumns - i) * PixelFormats.Gray8.BitsPerPixel + 7) / 8); System.Console.WriteLine("Got to undo change " + i.ToString()); System.Threading.Thread.Sleep(100); } } } Now, if I'm explicit in calling the garbage collector, I have to wrap the entire code in an outer loop to cause the OOM crash. For me, this tends to happen around x = 50 or so: public partial class Window1 : Window { public Window1() { InitializeComponent(); //Attempts to create an OOM crash //to do so, mimic minute croppings of an 'image' (ushort array), and then undoing the crops for (int x = 0; x < 1000; x++){ int theRows = 4000, currRows; int theColumns = 4000, currCols; int theMaxChange = 30; int i; List<ushort[]> theList = new List<ushort[]>();//the list of images in the undo/redo stack byte[] displayBuffer = null;//the buffer used as a bitmap source BitmapSource theSource = null; for (i = 0; i < theMaxChange; i++) { currRows = theRows - i; currCols = theColumns - i; theList.Add(new ushort[(theRows - i) * (theColumns - i)]); displayBuffer = new byte[theList[i].Length]; theSource = BitmapSource.Create(currCols, currRows, 96, 96, PixelFormats.Gray8, null, displayBuffer, (currCols * PixelFormats.Gray8.BitsPerPixel + 7) / 8); } //should get here. If not, then theMaxChange is too large. //Now, go back up the undo stack. for (i = theMaxChange - 1; i >= 0; i--) { displayBuffer = new byte[theList[i].Length]; theSource = BitmapSource.Create((theColumns - i), (theRows - i), 96, 96, PixelFormats.Gray8, null, displayBuffer, ((theColumns - i) * PixelFormats.Gray8.BitsPerPixel + 7) / 8); GC.WaitForPendingFinalizers();//force gc to collect, because we're in scenario 2, lots of large random changes GC.Collect(); } System.Console.WriteLine("Got to changelist " + x.ToString()); System.Threading.Thread.Sleep(100); } } } If I'm mishandling memory in either scenario, if there's something I should spot with a profiler, let me know. That's a pretty simple routine there. Unfortunately, it looks like @Kevin's answer is right-- this is a bug in .NET and how .NET handles objects larger than 85k. This situation strikes me as exceedingly strange; could Powerpoint be rewritten in .NET with this kind of limitation, or any of the other Office suite applications? 85k does not seem to me to be a whole lot of space, and I'd also think that any program that uses so-called 'large' allocations frequently would become unstable within a matter of days to weeks when using .NET. EDIT: It looks like Kevin is right, this is a limitation of .NET's GC. For those who don't want to follow the entire thread, .NET has four GC heaps: gen0, gen1, gen2, and LOH (Large Object Heap). Everything that's 85k or smaller goes on one of the first three heaps, depending on creation time (moved from gen0 to gen1 to gen2, etc). Objects larger than 85k get placed on the LOH. The LOH is never compacted, so eventually, allocations of the type I'm doing will eventually cause an OOM error as objects get scattered about that memory space. We've found that moving to .NET 4.0 does help the problem somewhat, delaying the exception, but not preventing it. To be honest, this feels a bit like the 640k barrier-- 85k ought to be enough for any user application (to paraphrase this video of a discussion of the GC in .NET). For the record, Java does not exhibit this behavior with its GC.

  - by TheAmazingKnight

  I am constructing a simple quiz using html and php. The problem I'm having is that I'm not sure how to do event handlers since it's my first time doing php. Simply, the user click on Take Quiz and it brings up the quiz, then submit the quiz using the same page and show score results. The quiz was written in HTML as shown below: HTML CODE: <section> <h1 id="theme"><span class="initial">Q</span>uiz</h1> <div id="message">Why not go ahead and take the quiz to test your knowledge based on what you've learned in Smartphone Photography.

• scrolling lags in emacs 23.2 with GTK

  - by mefiX

  Hey there, I am using emacs 23.2 with the GTK toolkit. I built emacs from source using the following configure-params: ./configure --prefix=/usr --without-makeinfo --without-sound Which builds emacs with the following configuration: Where should the build process find the source code? /home/****/incoming/emacs-23.2 What operating system and machine description files should Emacs use? `s/gnu-linux.h' and `m/intel386.h' What compiler should emacs be built with? gcc -g -O2 -Wdeclaration-after-statement -Wno-pointer-sign Should Emacs use the GNU version of malloc? yes (Using Doug Lea's new malloc from the GNU C Library.) Should Emacs use a relocating allocator for buffers? yes Should Emacs use mmap(2) for buffer allocation? no What window system should Emacs use? x11 What toolkit should Emacs use? GTK Where do we find X Windows header files? Standard dirs Where do we find X Windows libraries? Standard dirs Does Emacs use -lXaw3d? no Does Emacs use -lXpm? yes Does Emacs use -ljpeg? yes Does Emacs use -ltiff? yes Does Emacs use a gif library? yes -lgif Does Emacs use -lpng? yes Does Emacs use -lrsvg-2? no Does Emacs use -lgpm? yes Does Emacs use -ldbus? yes Does Emacs use -lgconf? no Does Emacs use -lfreetype? yes Does Emacs use -lm17n-flt? no Does Emacs use -lotf? yes Does Emacs use -lxft? yes Does Emacs use toolkit scroll bars? yes When I'm scrolling within files of a common size (about 1000 lines) holding the up/down-keys, emacs almost hangs and produces about 50% CPU-load. I use the following plugins: ido linum tabbar auto-complete-config Starting emacs with -q fixes the problem, but then I don't have any plugins. I can't figure out, which part of my .emacs is responsible for this behaviour. Here's an excerpt of my .emacs-file: (require 'ido) (ido-mode 1) (require 'linum) (global-linum-mode 1) (require 'tabbar) (tabbar-mode 1) (tabbar-local-mode 0) (tabbar-mwheel-mode 0) (setq tabbar-buffer-groups-function (lambda () (list "All"))) (global-set-key [M-left] 'tabbar-backward) (global-set-key [M-right] 'tabbar-forward) ;; hide the toolbar (gtk etc.) (tool-bar-mode -1) ;; Mouse scrolling enhancements (setq mouse-wheel-progressive-speed nil) (setq mouse-wheel-scroll-amount '(5 ((shift) . 5) ((control) . nil))) ;; Smart-HOME (defun smart-beginning-of-line () "Forces the cursor to jump to the first none whitespace char of the current line when pressing HOME" (interactive) (let ((oldpos (point))) (back-to-indentation) (and (= oldpos (point)) (beginning-of-line)))) (put 'smart-beginning-of-line 'CUA 'move) (global-set-key [home] 'smart-beginning-of-line) (custom-set-variables ;; custom-set-variables was added by Custom. ;; If you edit it by hand, you could mess it up, so be careful. ;; Your init file should contain only one such instance. ;; If there is more than one, they won't work right.

Any ideas? Let me make this more clear: a MVC page uses the spring part trying to load a lazy-init service which constructor wants a connection string through a static property like this: <object id="promotionRepos" type="ECommerce.Data.AdoNet.Promotions.PromotionRepos, ECommerce.Data.AdoNet" lazy-init="true"> <constructor-arg name="provider"> <null /> </constructor-arg> <constructor-arg name="connStr"> <object type="ECommerce.ERP.DAL.DBConn, ECommerce.ERP.DAL" factory-method="get_ConnString" /> </constructor-arg> <property name="RefreshInterval" value="00:00:10" /> </object> the timeout part is some what irrelevent to all others. see this in the first exception: Shopping_Shopping.Page_Load(Object sender, EventArgs e) +10 it's another page at all. And also, ECommerce.PMethod.Sql.SqlConns.Open() uses its own connection string, not the one loaded by spring, it's different module from diffrent team. And I am sure the connection string is correct. And, this ysod cames up randomly. Sometimes nothing is wrong, and sometimes, it appears. I thought there could be something wrong with my database or the network/firewall, I will check it later, but now I want understand this tricky stack trace.

• Floats will not align, stay staggered, can't find a solution?

  - by Sarah Proper

  What I am trying to do is build a multi column layout. The main two sections are divided 2/3 to 1/3 and inside the 2/3 column is divided 2/3 1/3 as well. My problem is that my floats will not align nicely with each other, choosing instead to stagger like stairs. I have tried declaring the widths smaller, floating them individually, including in the float sections display:block,inline, or inline-block and nothing seems to be working. I am getting really frustrated and would appreciate any help!
