• 'normal' SVC versus 'Silverlight' SVC (WCF)

  - by Michel

  Hi, i'm trying to call a WCF service from my Silverlight 3 app. But... when trying to create a 'silverlight enabled wcf service' in my web project, my VS2008 crashes during creating the item (i think while editing the web.config). So i thought: let's create a 'normal' wcf service, and manually edit it to be a 'silverlight enabled webservice'. So i wondered what the differences are, and second: why is there a difference between a service called from a silverlight app and a non-silverlight app? This is what i have now for the binding (i have a service without an Interface contract, just a direct class exposed, to begin with): <system.serviceModel> <behaviors> <serviceBehaviors> <behavior name="RadControlsSilverlightApp1.Web.GetNewDataBehavior"> <serviceMetadata httpGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="false" /> </behavior> </serviceBehaviors> </behaviors> <bindings> <customBinding> <binding name="customBinding0"> <binaryMessageEncoding /> <httpTransport /> </binding> </customBinding> </bindings> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" /> <services> <service behaviorConfiguration="RadControlsSilverlightApp1.Web.GetNewDataBehavior" name="RadControlsSilverlightApp1.Web.GetNewData"> <endpoint address="" binding="customBinding" bindingConfiguration="customBinding0" contract="RadControlsSilverlightApp1.Web.GetNewData" /> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> </system.serviceModel> This one doesn't work because when i add a reference to it from the silverlight app i get these messages: Warning 2 Custom tool warning: Cannot import wsdl:portType Detail: An exception was thrown while running a WSDL import extension: System.ServiceModel.Description.DataContractSerializerMessageContractImporter Error: Exception has been thrown by the target of an invocation.

• SQLAlchemy session management in long-running process

  - by codeape

  Scenario: A .NET-based application server (Wonderware IAS/System Platform) hosts automation objects that communicate with various equipment on the factory floor. CPython is hosted inside this application server (using Python for .NET). The automation objects have scripting functionality built-in (using a custom, .NET-based language). These scripts call Python functions. The Python functions are part of a system to track Work-In-Progress on the factory floor. The purpose of the system is to track the produced widgets along the process, ensure that the widgets go through the process in the correct order, and check that certain conditions are met along the process. The widget production history and widget state is stored in a relational database, this is where SQLAlchemy plays its part. For example, when a widget passes a scanner, the automation software triggers the following script (written in the application server's custom scripting language): ' wiget_id and scanner_id provided by automation object ' ExecFunction() takes care of calling a CPython function retval = ExecFunction("WidgetScanned", widget_id, scanner_id); ' if the python function raises an Exception, ErrorOccured will be true ' in this case, any errors should cause the production line to stop. if (retval.ErrorOccured) then ProductionLine.Running = False; InformationBoard.DisplayText = "ERROR: " + retval.Exception.Message; InformationBoard.SoundAlarm = True end if; The script calls the WidgetScanned python function: # pywip/functions.py from pywip.database import session from pywip.model import Widget, WidgetHistoryItem from pywip import validation, StatusMessage from datetime import datetime def WidgetScanned(widget_id, scanner_id): widget = session.query(Widget).get(widget_id) validation.validate_widget_passed_scanner(widget, scanner) # raises exception on error widget.history.append(WidgetHistoryItem(timestamp=datetime.now(), action=u"SCANNED", scanner_id=scanner_id)) widget.last_scanner = scanner_id widget.last_update = datetime.now() return StatusMessage("OK") # ... there are a dozen similar functions My question is: How do I best manage SQLAlchemy sessions in this scenario? The application server is a long-running process, typically running months between restarts. The application server is single-threaded. Currently, I do it the following way: I apply a decorator to the functions I make avaliable to the application server: # pywip/iasfunctions.py from pywip import functions def ias_session_handling(func): def _ias_session_handling(*args, **kwargs): try: retval = func(*args, **kwargs) session.commit() return retval except: session.rollback() raise return _ias_session_handling # ... actually I populate this module with decorated versions of all the functions in pywip.functions dynamically WidgetScanned = ias_session_handling(functions.WidgetScanned) Question: Is the decorator above suitable for handling sessions in a long-running process? Should I call session.remove()? The SQLAlchemy session object is a scoped session: # pywip/database.py from sqlalchemy.orm import scoped_session, sessionmaker session = scoped_session(sessionmaker()) I want to keep the session management out of the basic functions. For two reasons: There is another family of functions, sequence functions. The sequence functions call several of the basic functions. One sequence function should equal one database transaction. I need to be able to use the library from other environments. a) From a TurboGears web application. In that case, session management is done by TurboGears. b) From an IPython shell. In that case, commit/rollback will be explicit. (I am truly sorry for the long question. But I felt I needed to explain the scenario. Perhaps not necessary?)

• Process spawned by exec-maven-plugin blocks the maven process

  - by Arnab Biswas

  I am trying to execute the following scenario using maven : pre-integration-phase : Start a java based application using a main class (using exec-maven-plugin) integration-phase : Run the integration test cases (using maven-failsafe-plugin) post-integration-phase: Stop the application gracefully (using exec-maven-plugin) Here is pom.xml snip: <plugins> <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>exec-maven-plugin</artifactId> <version>1.2.1</version> <executions> <execution> <id>launch-myApp</id> <phase>pre-integration-test</phase> <goals> <goal>exec</goal> </goals> </execution> </executions> <configuration> <executable>java</executable> <arguments> <argument>-DMY_APP_HOME=/usr/home/target/local</argument> <argument>-Djava.library.path=/usr/home/other/lib</argument> <argument>-classpath</argument> <classpath/> <argument>com.foo.MyApp</argument> </arguments> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-failsafe-plugin</artifactId> <version>2.12</version> <executions> <execution> <goals> <goal>integration-test</goal> <goal>verify</goal> </goals> </execution> </executions> <configuration> <forkMode>always</forkMode> </configuration> </plugin> </plugins> If I execute mvn post-integration-test, my application is getting started as a child process of the maven process, but the application process is blocking the maven process from executing the integration tests which comes in the next phase. Later I found that there is a bug (or missing functionality?) in maven exec plugin, because of which the application process blocks the maven process. To address this issue, I have encapsulated the invocation of MyApp.java in a shell script and then appended “/dev/null 2&1 &” to spawn a separate background process. Here is the snip (this is just a snip and not the actual one) from runTest.sh: java - DMY_APP_HOME =$2 com.foo.MyApp > /dev/null 2>&1 & Although this solves my issue, is there any other way to do it? Am I missing any argument for exec-maven-plugin?

• Neo4j OutOfMemory problem

  Hi! This is my source code of Main.java. It was grabbed from neo4j-apoc-1.0 examples.

• My VARCHAR(MAX) field is capping itself at 4000; what gives?

  - by eidylon

  Hello all... I have a table in one of my databases which is a queue of emails. Emails to certain addresses get accumulated into one email, which is done by a sproc. In the sproc, I have a table variable which I use to build the accumulated bodies of the emails, and then loop through to send each email. In my table var I have my body column defined as VARCHAR(MAX), seeing as there could be any number of emails currently accumulated for a given email address. It seems though that even though my column is defined as VARCHAR(MAX) it is behaving as if it were VARCHAR(4000) and is truncating the data going into it, although it does NOT throw any exceptions, it just silently stops concatenating any more data after 4000 characters. The MERGE statement is where it is building the accumulated email body into @EMAILS.BODY, which is the field that is truncating itself at 4000 characters. Below is the code of my sproc... ALTER PROCEDURE [system].[SendAccumulatedEmails] AS BEGIN SET NOCOUNT ON; DECLARE @SENTS BIGINT = 0; DECLARE @ROWS TABLE ( ROWID ROWID, DATED DATETIME, ADDRESS NAME, SUBJECT VARCHAR(1000), BODY VARCHAR(MAX) ) INSERT INTO @ROWS SELECT ROWID, DATED, ADDRESS, SUBJECT, BODY FROM system.EMAILQUEUE WHERE ACCUMULATE = 1 AND SENT IS NULL ORDER BY ADDRESS, DATED DECLARE @EMAILS TABLE ( ADDRESS NAME, ALLIDS VARCHAR(1000), BODY VARCHAR(MAX) ) DECLARE @PRVRID ROWID = NULL, @CURRID ROWID = NULL SELECT @CURRID = MIN(ROWID) FROM @ROWS WHILE @CURRID IS NOT NULL BEGIN MERGE @EMAILS AS DST USING (SELECT * FROM @ROWS WHERE ROWID = @CURRID) AS SRC ON SRC.ADDRESS = DST.ADDRESS WHEN MATCHED THEN UPDATE SET DST.ALLIDS = DST.ALLIDS + ', ' + CONVERT(VARCHAR,ROWID), DST.BODY = DST.BODY + '<i>'+CONVERT(VARCHAR,SRC.DATED,101)+' ' +CONVERT(VARCHAR,SRC.DATED,8) +':</i> <b>'+SRC.SUBJECT+'</b>'+CHAR(13)+SRC.BODY +' (Message ID '+CONVERT(VARCHAR,SRC.ROWID)+')' +CHAR(13)+CHAR(13) WHEN NOT MATCHED BY TARGET THEN INSERT (ADDRESS, ALLIDS, BODY) VALUES ( SRC.ADDRESS, CONVERT(VARCHAR,ROWID), '<i>'+CONVERT(VARCHAR,SRC.DATED,101)+' ' +CONVERT(VARCHAR,SRC.DATED,8)+':</i> <b>' +SRC.SUBJECT+'</b>'+CHAR(13)+SRC.BODY +' (Message ID '+CONVERT(VARCHAR,SRC.ROWID)+')' +CHAR(13)+CHAR(13)); SELECT @PRVRID = @CURRID, @CURRID = NULL SELECT @CURRID = MIN(ROWID) FROM @ROWS WHERE ROWID > @PRVRID END DECLARE @MAILFROM VARCHAR(100) = system.getOption('MAILFROM'), DECLARE @SMTPHST VARCHAR(100) = system.getOption('SMTPSERVER'), DECLARE @SMTPUSR VARCHAR(100) = system.getOption('SMTPUSER'), DECLARE @SMTPPWD VARCHAR(100) = system.getOption('SMTPPASS') DECLARE @ADDRESS NAME, @BODY VARCHAR(MAX), @ADDL VARCHAR(MAX) DECLARE @SUBJECT VARCHAR(1000) = 'Accumulated Emails from LIJSL' DECLARE @PRVID NAME = NULL, @CURID NAME = NULL SELECT @CURID = MIN(ADDRESS) FROM @EMAILS WHILE @CURID IS NOT NULL BEGIN SELECT @ADDRESS = ADDRESS, @BODY = BODY FROM @EMAILS WHERE ADDRESS = @CURID SELECT @BODY = @BODY + 'This is an automated message sent from an unmonitored mailbox.'+CHAR(13)+'Do not reply to this message; your message will not be read.'

• Performance in backpropagation algorithm

  - by Taban

  I've written a matlab program for standard backpropagation algorithm, it is my homework and I should not use matlab toolbox, so I write the entire code by myself. This link helped me for backpropagation algorithm. I have a data set of 40 random number and initial weights randomly. As output, I want to see a diagram that shows the performance. I used mse and plot function to see performance for 20 epochs but the result is this: I heard that performance should go up through backpropagation, so I want to know is there any problem with my code or this result is normal because local minimums. This is my code: Hidden_node=inputdlg('Enter the number of Hidden nodes'); a=0.5;%initialize learning rate hiddenn=str2num(Hidden_node{1,1}); randn('seed',0); %creating data set s=2; N=10; m=[5 -5 5 5;-5 -5 5 -5]; S = s*eye(2); [l,c] = size(m); x = []; % Creating the training set for i = 1:c x = [x mvnrnd(m(:,i)',S,N)']; end % target value toutput=[ones(1,N) zeros(1,N) ones(1,N) zeros(1,N)]; for epoch=1:20; %number of epochs for kk=1:40; %number of patterns %initial weights of hidden layer for ii=1 : 2; for jj=1 :hiddenn; whidden{ii,jj}=rand(1); end end initial the wights of output layer for ii=1 : hiddenn; woutput{ii,1}=rand(1); end for ii=1:hiddenn; x1=x(1,kk); x2=x(2,kk); w1=whidden{1,ii}; w2=whidden{2,ii}; activation{1,ii}=(x1(1,1)*w1(1,1))+(x2(1,1)*w2(1,1)); end %calculate output of hidden nodes for ii=1:hiddenn; hidden_to_out{1,ii}=logsig(activation{1,ii}); end activation_O{1,1}=0; for jj=1:hiddenn; activation_O{1,1} = activation_O{1,1}+(hidden_to_out{1,jj}*woutput{jj,1}); end %calculate output out{1,1}=logsig(activation_O{1,1}); out_for_plot(1,kk)= out{1,ii}; %calculate error for output node delta_out{1,1}=(toutput(1,kk)-out{1,1}); %update weight of output node for ii=1:hiddenn; woutput{ii,jj}=woutput{ii,jj}+delta_out{1,jj}*hidden_to_out{1,ii}*dlogsig(activation_O{1,jj},logsig(activation_O{1,jj}))*a; end %calculate error of hidden nodes for ii=1:hiddenn; delta_hidden{1,ii}=woutput{ii,1}*delta_out{1,1}; end %update weight of hidden nodes for ii=1:hiddenn; for jj=1:2; whidden{jj,ii}= whidden{jj,ii}+(delta_hidden{1,ii}*dlogsig(activation{1,ii},logsig(activation{1,ii}))*x(jj,kk)*a); end end a=a/(1.1);%decrease learning rate end %calculate performance e=toutput(1,kk)-out_for_plot(1,1); perf(1,epoch)=mse(e); end plot(perf); Thanks a lot.

• Cocoa nextEventMatchingMask not receiving NSMouseMoved event

  - by Jonny

  Hello, I created a local event loop and showed up a borderless window (derived from NSPanel), I found in the event loop there's no NSMouseMoved event received, although I can receive Mouse button down/up events. What should I do to get the NSMouseMoved events? I found making the float window as key window can receive the NSMouseMoved events, but I don't want to change key window. And it appears this is possible, because I found after clicking the test App Icon in System Dock Bar, I can receive the mousemoved events, and the key window/mainwindow are unchanged. Here's the my test code: (Create a Cocoa App project names FloatWindowTest, and put a button to link it with the onClick: IBAction). Thanks in advance! -Jonny #import "FloatWindowTestAppDelegate.h" @interface FloatWindow : NSPanel @end @interface FloatWindowContentView : NSView @end @implementation FloatWindowTestAppDelegate @synthesize window; - (void)delayedAction:(id)sender { // What does this function do? // 1. create a float window // 2. create a local event loop // 3. print out the events got from nextEventMatchingMask. // 4. send it to float window. // What is the problem? // In local event loop, althrough the event mask has set NSMouseMovedMask // there's no mouse moved messages received. // FloatWindow* floatWindow = [[FloatWindow alloc] init]; NSEvent* event = [NSApp currentEvent]; NSPoint screenOrigin = [[self window] convertBaseToScreen:[event locationInWindow]]; [floatWindow setFrameTopLeftPoint:screenOrigin]; [floatWindow orderFront:nil]; //Making the float window as Key window will work, however //change active window is not anticipated. //[floatWindow makeKeyAndOrderFront:nil]; BOOL done = NO; while (!done) { NSAutoreleasePool* pool = [NSAutoreleasePool new]; NSUInteger eventMask = NSLeftMouseDownMask| NSLeftMouseUpMask| NSMouseMovedMask| NSMouseEnteredMask| NSMouseExitedMask| NSLeftMouseDraggedMask; NSEvent* event = [NSApp nextEventMatchingMask:eventMask untilDate:[NSDate distantFuture] inMode:NSDefaultRunLoopMode dequeue:YES]; //why I cannot get NSMouseMoved event??

• Servlet/JSP Flow Control: Enums, Exceptions, or Something Else?

  - by Christopher Parker

  I recently inherited an application developed with bare servlets and JSPs (i.e.: no frameworks). I've been tasked with cleaning up the error-handling workflow. Currently, each <form> in the workflow submits to a servlet, and based on the result of the form submission, the servlet does one of two things: If everything is OK, the servlet either forwards or redirects to the next page in the workflow. If there's a problem, such as an invalid username or password, the servlet forwards to a page specific to the problem condition. For example, there are pages such as AccountDisabled.jsp, AccountExpired.jsp, AuthenticationFailed.jsp, SecurityQuestionIncorrect.jsp, etc. I need to redesign this system to centralize how problem conditions are handled. So far, I've considered two possible solutions: Exceptions Create an exception class specific to my needs, such as AuthException. Inherit from this class to be more specific when necessary (e.g.: InvalidUsernameException, InvalidPasswordException, AccountDisabledException, etc.). Whenever there's a problem condition, throw an exception specific to the condition. Catch all exceptions via web.xml and route them to the appropriate page(s) with the <error-page> tag. enums Adopt an error code approach, with an enum keeping track of the error code and description. The descriptions can be read from a resource bundle in the finished product. I'm leaning more toward the enum approach, as an authentication failure isn't really an "exceptional condition" and I don't see any benefit in adding clutter to the server logs. Plus, I'd just be replacing one maintenance headache with another. Instead of separate JSPs to maintain, I'd have separate Exception classes. I'm planning on implementing "error" handling in a servlet that I'm writing specifically for this purpose. I'm also going to eliminate all of the separate error pages, instead setting an error request attribute with the error message to display to the user and forwarding back to the referrer. Each target servlet (Logon, ChangePassword, AnswerProfileQuestions, etc.) would add an error code to the request and redirect to my new servlet in the event of a problem. My new servlet would look something like this: public enum Error { INVALID_PASSWORD(5000, "You have entered an invalid password."), ACCOUNT_DISABLED(5002, "Your account has been disabled."), SESSION_EXPIRED(5003, "Your session has expired. Please log in again."), INVALID_SECURITY_QUESTION(5004, "You have answered a security question incorrectly."); private final int code; private final String description; Error(int code, String description) { this.code = code; this.description = description; } public int getCode() { return code; } public String getDescription() { return description; } }; protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { String sendTo = "UnknownError.jsp"; String message = "An unknown error has occurred."; int errorCode = Integer.parseInt((String)request.getAttribute("errorCode"), 10); Error errors[] = Error.values(); Error error = null; for (int i = 0; error == null && i < errors.length; i++) { if (errors[i].getCode() == errorCode) { error = errors[i]; } } if (error != null) { sendTo = request.getHeader("referer"); message = error.getDescription(); } request.setAttribute("error", message); request.getRequestDispatcher(sendTo).forward(request, response); } protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { doGet(request, response); } Being fairly inexperienced with Java EE (this is my first real exposure to JSPs and servlets), I'm sure there's something I'm missing, or my approach is suboptimal. Am I on the right track, or do I need to rethink my strategy?

• 3D game engine for networked world simulation / AI sandbox

  - by Martin

  More than 5 years ago I was playing with DirectSound and Direct3D and I found it really exciting although it took much time to get some good results with C++. I was a college student then. Now I have mostly enterprise development experience in C# and PHP, and I do it for living. There is really no chance to earn money with serious game development in our country. Each day more and more I find that I miss something. So I decided to spend an hour or so each day to do programming for fun. So my idea is to build a world simulation. I would like to begin with something simple - some human-like creatures that live their life - like Sims 3 but much more simple, just basic needs, basic animations, minimum graphic assets - I guess it won't be a city but just a large house for a start. The idea is to have some kind of a server application which stores the world data in MySQL database, and some client applications - body-less AI bots which simulate movement and some interactions with the world and each other. But it wouldn't be fun without 3D. So there are also 3D clients - I can enter that virtual world and see the AI bots living. When the bot enters visible area, it becomes material - loads a mesh and animations, so I can see it. When I leave, the bots lose their 3d mesh bodies again, but their virtual life still continues. With time I hope to make it like some expandable scriptable sandbox to experiment with various AI algorithms and so on. But I am not intended to create a full-blown MMORPG :D I have looked for many possible things I would need (free and open source) and now I have to make a choice: OGRE3D + enet (or RakNet). Old good C++. But won't it slow me down so much that I won't have fun any more? CrystalSpace. Formally not a game engine but very close to that. C++ again. MOgre (OGRE3D wrapper for .NET) + lidgren (networking library which is already used in some gaming projects). Good - I like C#, it is good for fast programming and also can be used for scripting. XNA seems just a framework, not an engine, so really have doubts, should I even look at XNA Game Studio :( Panda3D - full game engine with positive feedback. I really like idea to have all the toolset in one package, it has good reviews as a beginner-friendly engine...if you know Python. On the C++ side, Panda3D has almost non-existent documentation. I have 0 experience with Python, but I've heard it is easy to learn. And if it will be fun and challenging then I guess I would benefit from experience in one more programming language. Which of those would you suggest, not because of advanced features or good platform support but mostly for fun, easy workflow and expandability, and so I can create and integrate all the components I need - the server with the database, AI bots and a 3D client application?

• Visitor and templated virtual methods

  - by Thomas Matthews

  In a typical implementation of the Visitor pattern, the class must account for all variations (descendants) of the base class. There are many instances where the same method content in the visitor is applied to the different methods. A templated virtual method would be ideal in this case, but for now, this is not allowed. So, can templated methods be used to resolve virtual methods of the parent class? Given (the foundation): struct Visitor_Base; // Forward declaration. struct Base { virtual accept_visitor(Visitor_Base& visitor) = 0; }; // More forward declarations struct Base_Int; struct Base_Long; struct Base_Short; struct Base_UInt; struct Base_ULong; struct Base_UShort; struct Visitor_Base { virtual void operator()(Base_Int& b) = 0; virtual void operator()(Base_Long& b) = 0; virtual void operator()(Base_Short& b) = 0; virtual void operator()(Base_UInt& b) = 0; virtual void operator()(Base_ULong& b) = 0; virtual void operator()(Base_UShort& b) = 0; }; struct Base_Int : public Base { void accept_visitor(Visitor_Base& visitor) { visitor(*this); } }; struct Base_Long : public Base { void accept_visitor(Visitor_Base& visitor) { visitor(*this); } }; struct Base_Short : public Base { void accept_visitor(Visitor_Base& visitor) { visitor(*this); } }; struct Base_UInt : public Base { void accept_visitor(Visitor_Base& visitor) { visitor(*this); } }; struct Base_ULong : public Base { void accept_visitor(Visitor_Base& visitor) { visitor(*this); } }; struct Base_UShort : public Base { void accept_visitor(Visitor_Base& visitor) { visitor(*this); } }; Now that the foundation is laid, here is where the kicker comes in (templated methods): struct Visitor_Cout : public Visitor { template <class Receiver> void operator() (Receiver& r) { std::cout << "Visitor_Cout method not implemented.\n"; } }; Intentionally, Visitor_Cout does not contain the keyword virtual in the method declaration. All the other attributes of the method signatures match the parent declaration (or perhaps specification). In the big picture, this design allows developers to implement common visitation functionality that differs only by the type of the target object (the object receiving the visit). The implementation above is my suggestion for alerts when the derived visitor implementation hasn't implement an optional method. Is this legal by the C++ specification? (I don't trust when some says that it works with compiler XXX. This is a question against the general language.)

It seems to choke after the line "dv = sds.Select(New DataSourceSelectArguments())" in the code.

• Calling webservice from WCF service

  - by Balaji

  I am having an issue consuming a webservice (c#.net) from a WCF service. The error i am getting is EndPointNotFoundException "TCP error code 10061: No connection could be made because the target machine actively refused it" I wrote a unit test to check if i could send a request to the web service and it worked fine [The unit test is using the same binding configuration as my WCF service] The web service and WCF service (client) have basichttp binding. Did anyone had similar kind of issue calling a webservice from a WCF service? The service Model section is as follows <system.serviceModel> <bindings> <basicHttpBinding> <binding name="DataService" closeTimeout="00:05:00" openTimeout="00:05:00" receiveTimeout="00:10:00" sendTimeout="00:05:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384"/> <security mode="None"> <transport clientCredentialType="None" proxyCredentialType="None" realm=""/> <message clientCredentialType="UserName" algorithmSuite="Default"/> </security> </binding> </basicHttpBinding> </bindings> <client> <endpoint address="http://10.22.33.67/Service/DataService.asmx" binding="basicHttpBinding" bindingConfiguration="DataService" contract="Service.DataService" name="DataService"/> </client> <services> <service name="TestToConsumeDataService.WCFHost.Service1" behaviorConfiguration="TestToConsumeDataService.WCFHost.Service1Behavior"> <!-- Service Endpoints --> <endpoint address="" binding="basicHttpBinding" contract="TestToConsumeDataService.WCFHost.IService1"> <!-- Upon deployment, the following identity element should be removed or replaced to reflect the identity under which the deployed service runs.

• Clipplanes, vertex shaders and hardware vertex processing in Direct3D 9

  - by Igor

  Hi, I have an issue with clipplanes in my application that I can reproduce in a sample from DirectX SDK (February 2010). I added a clipplane to the HLSLwithoutEffects sample: ... D3DXPLANE g_Plane( 0.0f, 1.0f, 0.0f, 0.0f ); ... void SetupClipPlane(const D3DXMATRIXA16 & view, const D3DXMATRIXA16 & proj) { D3DXMATRIXA16 m = view * proj; D3DXMatrixInverse( &m, NULL, &m ); D3DXMatrixTranspose( &m, &m ); D3DXPLANE plane; D3DXPlaneNormalize( &plane, &g_Plane ); D3DXPLANE clipSpacePlane; D3DXPlaneTransform( &clipSpacePlane, &plane, &m ); DXUTGetD3D9Device()->SetClipPlane( 0, clipSpacePlane ); } void CALLBACK OnFrameMove( double fTime, float fElapsedTime, void* pUserContext ) { // Update the camera's position based on user input g_Camera.FrameMove( fElapsedTime ); // Set up the vertex shader constants D3DXMATRIXA16 mWorldViewProj; D3DXMATRIXA16 mWorld; D3DXMATRIXA16 mView; D3DXMATRIXA16 mProj; mWorld = *g_Camera.GetWorldMatrix(); mView = *g_Camera.GetViewMatrix(); mProj = *g_Camera.GetProjMatrix(); mWorldViewProj = mWorld * mView * mProj; g_pConstantTable->SetMatrix( DXUTGetD3D9Device(), "mWorldViewProj", &mWorldViewProj ); g_pConstantTable->SetFloat( DXUTGetD3D9Device(), "fTime", ( float )fTime ); SetupClipPlane( mView, mProj ); } void CALLBACK OnFrameRender( IDirect3DDevice9* pd3dDevice, double fTime, float fElapsedTime, void* pUserContext ) { // If the settings dialog is being shown, then // render it instead of rendering the app's scene if( g_SettingsDlg.IsActive() ) { g_SettingsDlg.OnRender( fElapsedTime ); return; } HRESULT hr; // Clear the render target and the zbuffer V( pd3dDevice->Clear( 0, NULL, D3DCLEAR_TARGET | D3DCLEAR_ZBUFFER, D3DCOLOR_ARGB( 0, 45, 50, 170 ), 1.0f, 0 ) ); // Render the scene if( SUCCEEDED( pd3dDevice->BeginScene() ) ) { pd3dDevice->SetVertexDeclaration( g_pVertexDeclaration ); pd3dDevice->SetVertexShader( g_pVertexShader ); pd3dDevice->SetStreamSource( 0, g_pVB, 0, sizeof( D3DXVECTOR2 ) ); pd3dDevice->SetIndices( g_pIB ); pd3dDevice->SetRenderState( D3DRS_CLIPPLANEENABLE, D3DCLIPPLANE0 ); V( pd3dDevice->DrawIndexedPrimitive( D3DPT_TRIANGLELIST, 0, 0, g_dwNumVertices, 0, g_dwNumIndices / 3 ) ); pd3dDevice->SetRenderState( D3DRS_CLIPPLANEENABLE, 0 ); RenderText(); V( g_HUD.OnRender( fElapsedTime ) ); V( pd3dDevice->EndScene() ); } } When I rotate the camera I have different visual results when using hardware and software vertex processing. In software vertex processing mode or when using the reference device the clipping plane works fine as expected. In hardware mode it seems to rotate with the camera. If I remove the call to RenderText(); from OnFrameRender then hardware rendering also works fine. Further debugging reveals that the problem is in ID3DXFont::DrawText. I have this issue in Windows Vista and Windows 7 but not in Windows XP. I tested the code with the latest NVidia and ATI drivers in all three OSes on different PCs. Is it a DirectX issue? Or incorrect usage of clipplanes? Thanks Igor

• twitter bootstrap collapsable nav menu

  - by clifgray

  I am using twitter bootstrap on my web app to do all of the styling and everything is great for the most part. The problem is that my nav bar, once collapsed, will not drop down when I click the dropdown icon. I have listed my HTML but I think the problem is with my javascript seeing as this fiddle with the exact same code: http://jsfiddle.net/YWUmb/30/ works just fine. <div class="navbar navbar-fixed-top"> <div class="navbar-inner"> <div class="container"> <a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse"> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </a> <a class="brand" href="/">Exployre</a> <div class="nav-collapse"> <ul class="nav"> <li><a href="/">Home</a></li> <li><a href="/profile">Profile</a></li> <li><a href="/sponsors">Sponsors</a></li> <li><a href="/working">Exployrers</a></li> <li><a href="/about">About</a></li> <li><a href="/share">Share</a></li> <li> {% if user %} User: {{ user }}<br> <a href="{{ logout }}">Logout</a> {% else %} <a href="/login">Signin or Register</a> {% endif %} <li> <a href="/profile"> {% if visits %} {% if visits > 10 %} Prestige: {{ visits }} {% elif visits > 5 %} {% endif %} {% endif %} </a> </li> <li> <form action="/search" class="navbar-search"> <div> <input type="text" placeholder="Search" class="search-query" name="q" size="55"/> </div> </form> <script type="text/javascript" src="http://www.google.com/coop/cse/brand?form=cse-search-box&amp;lang=en"></script> </li> </ul> </div><!--/.nav-collapse --> </div> </div> </div> <script type="text/javascript" src="/static/js/bootstrap.js"></script> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script> Is there anything wrong with my source code links or anything additional that I need to do to make it work?

• How do I get a Java to call data from the Internet? Where to even start??

  - by cdg

  Hello oh great wizards of all things android. I really need your help. Mostly because my little brain just doesn't know were to start.

• Run unit tests in Jenkins / Hudson in automated fashion from dev to build server

  - by Kevin Donde

  We are currently running a Jenkins (Hudson) CI server to build and package our .net web projects and database projects. Everything is working great but I want to start writing unit tests and then only passing the build if the unit tests pass. We are using the built in msbuild task to build the web project. With the following arguments ... MsBuild Version .NET 4.0 MsBuild Build File ./WebProjectFolder/WebProject.csproj Command Line Arguments ./target:Rebuild /p:Configuration=Release;DeployOnBuild=True;PackageLocation=".\obj\Release\WebProject.zip";PackageAsSingleFile=True We need to run automated tests over our code that run automatically when we build on our machines (post build event possibly) but also run when Jenkins does a build for that project. If you run it like this it doesn't build the unit tests project because the web project doesn't reference the test project. The test project would reference the web project but I'm pretty sure that would be butchering our automated builds as they exist primarily to build and package our deployments. Running these tests should be a step in that automated build and package process. Options ... Create two Jenkins jobs. one to run the tests ... if the tests pass another build is triggered which builds and packages the web project. Put the post build event on the test project. Build the solution instead of the project (make sure the solution contains the required tests) and put post build events on any test projects that would run the nunit console to run the tests. Then use the command line to copy all the required files from each of the bin and content directories into a package. Just build the test project in jenkins instead of the web project in jenkins. The test project would reference the web project (depending on what you're testing) and build it. Problems ... There's two jobs and not one. Two things to debug not one. One to see if the tests passed and one to build and compile the web project. The tests could pass but the build could fail if its something that isn't used by what you're testing ... This requires us to know exactly what goes into the build. Right now msbuild does it all for us. If you have multiple teams working on a project everytime an extra folder is created you have to worry about the possibly brittle command line statements. This seems like a corruption of our main purpose here. The tests should be a step in this process not the overriding most important thing in this process. I'm also not 100% sure that a triggered build is the same as a normal build does it do all the same things as a normal build. Move all the correct files in the same way move them all into the same directories etc. Initial problem. We want to run our tests whenever our main project is built. But adding a post build event to the web project that runs against the test project doesn't work because the web project doesn't reference the test project and won't trigger a build of this project. I could go on ... but that's enough ... We've spent about a week trying to make this work nicely but haven't succeeded. Feel free to edit this if you feel you can get a better response ...

• using PixelBender to double the size of a bitmap

  - by jedierikb

  I have a performance question about pixel bender. I want to enlarge many BitmapData (double their size into new BitmapData). I was doing this with as3, but wanted to use pixel bender to get better performance. On my machines, I get great comparative performance out of many pixel bender demonstrations. To my surprise (or bad coding / understanding), I am getting much worse performance out of pixel bender -- 2 seconds to do 3000 scalings vs .5 seconds! I expected to get at least the same performance as as3. What am I doing wrong? I got the straightforward pixel bender code here (and it is included below for easy reference). package { import aCore.aUtil.timingUtils; import flash.display.BitmapData; import flash.display.Shader; import flash.display.ShaderJob; import flash.display.Sprite; import flash.display.StageAlign; import flash.display.StageScaleMode; import flash.events.Event; import flash.geom.Matrix; public class flashFlash extends Sprite { [Embed ( source="pixelbender/bilinearresample.pbj", mimeType="application/octet-stream" ) ] private static var BilinearScaling:Class; public function flashFlash( ):void { stage.align = StageAlign.TOP_LEFT; stage.scaleMode = StageScaleMode.NO_SCALE; addEventListener( Event.ENTER_FRAME, efCb, false, 0, true ); } private function efCb( evt:Event ):void { removeEventListener( Event.ENTER_FRAME, efCb, false ); traceTime( "init" ); var srcBmd:BitmapData = new BitmapData( 80, 120, false, 0 ); var destBmd:BitmapData = new BitmapData( 160, 240, false, 0 ); var mx:Matrix = new Matrix( ); mx.scale( 2, 2 ); for (var i:uint = 0; i < 3000; i++) { destBmd.draw( srcBmd, mx ); } traceTime( "scaled with as3" ); // create and configure a Shader object var shader:Shader = new Shader( ); shader.byteCode = new BilinearScaling( ); shader.data.scale.value = [2]; shader.data.src.input = srcBmd; for (var j:uint = 0; j < 3000; j++) { var shaderJob:ShaderJob = new ShaderJob( ); shaderJob.shader = shader; shaderJob.target = destBmd; shaderJob.start( true ); } traceTime( "scaled with pixel bender bilinearresample.pbj" ); } private static var _lastTraceTime:Number = new Date().getTime(); public static function traceTime( note:String ):Number { var nowTime:Number = new Date().getTime(); var diff:Number = (nowTime-_lastTraceTime); trace( "[t" + diff + "] " + note ); _lastTraceTime = nowTime; return diff; } } } And the pixel bender code: <languageVersion : 1.0;> kernel BilinearResample < namespace : "com.brooksandrus.pixelbender"; vendor : "Brooks Andrus"; version : 1; description : "Resizes an image using bilinear resampling.

• highlight navigation PHP

  - by Kira

  I've launched a website a while back and successfully used Javascript + CSS to highlight the current page on the navigation. However, it is not working in Safari and it does not validate well, when using Javascript, so I decided to have PHP assign the CSS id to the HTML elements. So far, it works fine, compared to the other times where there was two of each link displayed, when it was attempted in PHP. My problem is that all links look normal and the CSS property is not applied. I have a feeling that it has to do with my PHP code, but I'm not certain. The site address is here As for the PHP code, here it is: <?php echo('<li><span class="bold">Main</span>'); echo('<ul>'); if ($page=="home") { echo('<li><a id="current" href="index.shtml">Home</a></li>'); } else { echo('<li><a href="index.shtml">Home</a></li>'); } if ($page=="faq") { echo('<li><a id="current" href="faq.shtml">FAQ</a></li>'); } else { echo('<li><a href="faq.shtml">FAQ</a></li>'); } if ($page=="about") { echo('<li><a id="current" href="about.shtml">About Bryce</a></li>'); } else { echo('<li><a href="about.shtml">About Bryce</a></li>'); } echo('<li><a href="contact.php">Contact Bryce</a></li>'); if ($page=="sign guestbook") { echo('<li><a id="current" href="sign.shtml">Sign Guestbook</a></li>'); } else { echo('<li><a href="sign.shtml">Sign Guestbook</a></li>'); } if ($page=="view guestbook") { echo('<li><a id="current" href="view.shtml">View Guestbook</a></li>'); } else { echo('<li><a href="view.shtml">View Guestbook</a></li>'); } echo('</ul>'); echo('</li>'); echo('<li><span class="bold">Info</span>'); echo('<ul>'); if ($page=="projects") { echo('<li><a id="current" href="projects.shtml">Projects</a></li>'); } else { echo('<li><a href="projects.shtml">Projects</a></li>'); } if ($page=="books") { echo('<li><a id="current" href="books.shtml">Books</a></li>'); } else { echo('<li><a href="books.shtml">Books</a></li>'); } echo('</ul>'); echo('</li>'); echo('<li><span class="bold">Misc.</span>'); echo('<ul>'); if ($page=="cover designs") { echo('<li><a id="current" href="coverdesigns.shtml">Cover Designs</a></li>'); } else { echo('<li><a href="coverdesigns.shtml">Cover Designs</a></li>'); } echo('<li><a target="_blank" href="http://www.lulu.com/brycecampbellsbooks">Lulu Store</a></li>'); echo('<li><a href="rss/">RSS</a></li>'); echo('</ul>'); echo('</li>'); ?> In order to give you guys an idea of what the highlighting effect should look like, here is the CSS that is supposed to be applied to the current page: #current { font-style: italic; text-decoration: none; color: #000000; } When looking up what I was doing wrong, it told me that I was implementing it right, but it does not seem that the PHP is getting the values.

• Why does BeginReceiveFrom never time out?

  - by James Hugard

  I am writing an asynchronous Ping using Raw Sockets in F#, to enable parallel requests using as few threads as possible ("System.Net.NetworkInformation.Ping" appears to use one thread per request, but have not tested this... also am interested in using F# async workflows). The synchronous version below correctly times out when the target host does not exist/respond, but the asynchronous version hangs. Both work when the host does respond... Any ideas? (note: the process must run as Admin for this code to work) This throws a timeout: let result = Ping.Ping ( IPAddress.Parse( "192.168.33.22" ), 1000 ) However, this hangs: let result = Ping.PingAsync ( IPAddress.Parse( "192.168.33.22" ), 1000 ) |> Async.RunSynchronously Here's the code... module Ping open System open System.Net open System.Net.Sockets open System.Threading //---- ICMP Packet Classes type IcmpMessage (t : byte) = let mutable m_type = t let mutable m_code = 0uy let mutable m_checksum = 0us member this.Type with get() = m_type member this.Code with get() = m_code member this.Checksum = m_checksum abstract Bytes : byte array default this.Bytes with get() = [| m_type m_code byte(m_checksum) byte(m_checksum >>> 8) |] member this.GetChecksum() = let mutable sum = 0ul let bytes = this.Bytes let mutable i = 0 // Sum up uint16s while i < bytes.Length - 1 do sum <- sum + uint32(BitConverter.ToUInt16( bytes, i )) i <- i + 2 // Add in last byte, if an odd size buffer if i <> bytes.Length then sum <- sum + uint32(bytes.[i]) // Shuffle the bits sum <- (sum >>> 16) + (sum &&& 0xFFFFul) sum <- sum + (sum >>> 16) sum <- ~~~sum uint16(sum) member this.UpdateChecksum() = m_checksum <- this.GetChecksum() type InformationMessage (t : byte) = inherit IcmpMessage(t) let mutable m_identifier = 0us let mutable m_sequenceNumber = 0us member this.Identifier = m_identifier member this.SequenceNumber = m_sequenceNumber override this.Bytes with get() = Array.append (base.Bytes) [| byte(m_identifier) byte(m_identifier >>> 8) byte(m_sequenceNumber) byte(m_sequenceNumber >>> 8) |] type EchoMessage() = inherit InformationMessage( 8uy ) let mutable m_data = Array.create 32 32uy do base.UpdateChecksum() member this.Data with get() = m_data and set(d) = m_data <- d this.UpdateChecksum() override this.Bytes with get() = Array.append (base.Bytes) (this.Data) //---- Synchronous Ping let Ping (host : IPAddress, timeout : int ) = let mutable ep = new IPEndPoint( host, 0 ) let socket = new Socket( AddressFamily.InterNetwork, SocketType.Raw, ProtocolType.Icmp ) socket.SetSocketOption( SocketOptionLevel.Socket, SocketOptionName.SendTimeout, timeout ) socket.SetSocketOption( SocketOptionLevel.Socket, SocketOptionName.ReceiveTimeout, timeout ) let packet = EchoMessage() let mutable buffer = packet.Bytes try if socket.SendTo( buffer, ep ) <= 0 then raise (SocketException()) buffer <- Array.create (buffer.Length + 20) 0uy let mutable epr = ep :> EndPoint if socket.ReceiveFrom( buffer, &epr ) <= 0 then raise (SocketException()) finally socket.Close() buffer //---- Entensions to the F# Async class to allow up to 5 paramters (not just 3) type Async with static member FromBeginEnd(arg1,arg2,arg3,arg4,beginAction,endAction,?cancelAction): Async<'T> = Async.FromBeginEnd((fun (iar,state) -> beginAction(arg1,arg2,arg3,arg4,iar,state)), endAction, ?cancelAction=cancelAction) static member FromBeginEnd(arg1,arg2,arg3,arg4,arg5,beginAction,endAction,?cancelAction): Async<'T> = Async.FromBeginEnd((fun (iar,state) -> beginAction(arg1,arg2,arg3,arg4,arg5,iar,state)), endAction, ?cancelAction=cancelAction) //---- Extensions to the Socket class to provide async SendTo and ReceiveFrom type System.Net.Sockets.Socket with member this.AsyncSendTo( buffer, offset, size, socketFlags, remoteEP ) = Async.FromBeginEnd( buffer, offset, size, socketFlags, remoteEP, this.BeginSendTo, this.EndSendTo ) member this.AsyncReceiveFrom( buffer, offset, size, socketFlags, remoteEP ) = Async.FromBeginEnd( buffer, offset, size, socketFlags, remoteEP, this.BeginReceiveFrom, (fun asyncResult -> this.EndReceiveFrom(asyncResult, remoteEP) ) ) //---- Asynchronous Ping let PingAsync (host : IPAddress, timeout : int ) = async { let ep = IPEndPoint( host, 0 ) use socket = new Socket( AddressFamily.InterNetwork, SocketType.Raw, ProtocolType.Icmp ) socket.SetSocketOption( SocketOptionLevel.Socket, SocketOptionName.SendTimeout, timeout ) socket.SetSocketOption( SocketOptionLevel.Socket, SocketOptionName.ReceiveTimeout, timeout ) let packet = EchoMessage() let outbuffer = packet.Bytes try let! result = socket.AsyncSendTo( outbuffer, 0, outbuffer.Length, SocketFlags.None, ep ) if result <= 0 then raise (SocketException()) let epr = ref (ep :> EndPoint) let inbuffer = Array.create (outbuffer.Length + 256) 0uy let! result = socket.AsyncReceiveFrom( inbuffer, 0, inbuffer.Length, SocketFlags.None, epr ) if result <= 0 then raise (SocketException()) return inbuffer finally socket.Close() }

• Clickonce installation fails after addition of WCF service project

  - by Ant

  So I have a winform solution, deployed via clickonce. Eveything worked fine until i added a WCF project. (see error in parsing the manifest file at end of post) Now I notice that MSBuild compiles the service into a _PublishedWebsites dir. I don't know what the need for this is, but I am suspecting this is the cause of the problem. This wcf project references some other projects within the solution. I am actually hosting the wcf service within the application so I don't really need MSBuild to do all this for me.

• How can I get my Web API app to run again after upgrading to MVC 5 and Web API 2?

  - by Clay Shannon

  I upgraded my Web API app to the funkelnagelneu versions using this guidance: http://www.asp.net/mvc/tutorials/mvc-5/how-to-upgrade-an-aspnet-mvc-4-and-web-api-project-to-aspnet-mvc-5-and-web-api-2 However, after going through the steps (it seems all this should be automated, anyway), I tried to run it and got, "A project with an Output Type of Class Library cannot be started directly" What in Sam Hills Brothers Coffee is going on here? Who said this was a class library? So I opened Project Properties, and changed it (it was marked as "Class Library" for some reason - it either wasn't yesterday, or was and worked fine) to an Output Type of "Windows Application" ("Console Application" and "Class Library" being the only other options). Now it won't compile, complaining: "*Program 'c:\Platypus_Server_WebAPI\PlatypusServerWebAPI\PlatypusServerWebAPI\obj\Debug\PlatypusServerWebAPI.exe' does not contain a static 'Main' method suitable for an entry point...*" How can I get my Web API app back up and running in view of this quandary? UPDATE Looking in packages.config, two entries seem chin-scratch-worthy: <package id="Microsoft.AspNet.Providers" version="1.2" targetFramework="net40" /> <package id="Microsoft.Web.Infrastructure" version="1.0.0.0" targetFramework="net40" /> All the others target net451. Could this be the problem? Should I remove these packages? UPDATE 2 I tried to uninstall the Microsoft.Web.Infrastructure package (its description leads me to believe I don't need it; also, it has no dependencies) via the NuGet package manager, but it tells me, "NuGet failed to install or uninstall the selected package in the following project(s). [mine]" UPDATE 3 I went through the steps in again, and found that I had missed one step. I had to change this entry in the Application web.config File : <dependentAssembly> <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" /> <bindingRedirect oldVersion="1.0.0.0-5.0.0.0" newVersion="5.0.0.0" /> </dependentAssembly> (from "4.0.0.0" to "5.0.0.0") ...but I still get the same result - it rebuilds/compiles, but won't run, with "A project with an Output Type of Class Library cannot be started directly" UPDATE 4 Thinking about the err msg, that it can't directly open a class library, I thought, "Sure you can't/won't -- this is a web app, not a project. So I followed a hunch, closed the project, and reopened it as a website (instead of reopening a project). That has gotten me further, at least; now I see a YSOD: Could not load file or assembly 'System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified. UPDATE 5 Note: The project is now (after being opened as a web site) named "localhost_48614" And...there is no longer a "References" folder...?!?!? As to that YSOD I'm getting, the official instructions (http://www.asp.net/mvc/tutorials/mvc-5/how-to-upgrade-an-aspnet-mvc-4-and-web-api-project-to-aspnet-mvc-5-and-web-api-2) said to do this, and I quote: "Update all elements that contain “System.Web.WebPages.Razor” from version “2.0.0.0” to version“3.0.0.0”." UPDATE 6 When I select Tools Library Package Manager Manage NuGet Packages for Solution now, I get, "Operation failed. Unable to locate the solution directory. Please ensure that the solution has been saved." So I save it, and it saves it with this funky new name (C:\Users\clay\Documents\Visual Studio 2013\Projects\localhost_48614\localhost_48614.sln) I get the Yellow Strip of Enlightenment across the top of the NuGet Package Manager telling me, "Some NuGet packages are missing from this solution. Click to restore from your online package sources." I do (click the "Restore" button, that is), and it downloads the missing packages ... I end up with the 30 packages. I try to run the app/site again, and ... the erstwhile YSOD becomes a compilation error: The pre-application start initialization method Start on type System.Web.Mvc.PreApplicationStartCode threw an exception with the following error message: Could not load file or assembly 'System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.. Argghhhh!!! (and it's not even talk-like-a-pirate day).

• How to parse HTML with TouchXML or some other alternative.

  - by 0SX

  Hi, I'm trying to parse the HTML presented below with TouchXML but it keeps crashing when I try to extract certain attributes. I'm totally new to the parser world so I apologize for being a complete idiot. I need help to parse this HTML. What I'm trying to accomplish is to parse each attribute and value or what not and copy them to a string. I've been trying to find a good parser to parse HTML and I believe TouchXML is the best I've seen because of Tidy. Speaking of Tidy, How could I run this HTML through Tidy first then parse it? I'm not sure how to do this. Here is the code that I have so far that doesn't work due to it's not pulling everything I need from the HTML. Any help or advice would be much appreciated. Thanks My current code: NSMutableArray *res = [[NSMutableArray alloc] init]; // using local resource file NSString *XMLPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"example.html"]; NSData *XMLData = [NSData dataWithContentsOfFile:XMLPath]; CXMLDocument *doc = [[[CXMLDocument alloc] initWithData:XMLData options:0 error:nil] autorelease]; NSArray *nodes = NULL; nodes = [doc nodesForXPath:@"//div" error:nil]; for (CXMLElement *node in nodes) { NSMutableDictionary *item = [[NSMutableDictionary alloc] init]; [item setObject:[[node attributeForName:@"id"] stringValue] forKey:@"id"]; [res addObject:item]; [item release]; } NSLog(@"%@", res); [res release]; HTML file that needs to be parsed: <html> <head> <base target="_blank" /> </head> <body style="margin:2;"> <div id="group"> <div id="groupURL"><a href="http://www.example.com/groups">Group URL</a></div> <img id="grouplogo" src="http://images.example.com/groups/image.png" /> <div id="groupcomputer"><a href="http://www.example.com/groups/page" title="Group Title">Group title this would be here</a></div> <div id="groupinfos"> <div id="groupinfo-l">Person</div><div id="groupinfo-r">Ralph</div> <div id="groupinfo-l">Years</div><div id="groupinfo-r">4 years</div> <div id="groupinfo-l">Salary</div><div id="groupinfo-r">100K</div> <div id="groupinfo-l">Other</div><div id="groupoth" style="width:15px">other info</div> </body> </html> EDIT: I could use Element Parser but I need to know how to extract the Person's Name from the following example which would be Ralph in this case. <div id="groupinfo-l">Person</div><div id="groupinfo-r">Ralph</div>
