  • get img src from an img loaded dynamically using jQuery

    - by Lee
    Hey Guys (and Ladies) I am looking at getting the image name from an image with a src loaded dynamically. Basically what I am doing is using the Google chat badge on a site to live chatting. And else where on the page, I have an image saying Live Chat:Online or Live Chat:Offline. And I want this to change depending on whether I am available to chat or not. Does this make sense? Anyway, the easiest way I figure to do this would be check the img url. If the img is offline.gif then obviously I am offline. An example of a dynamically loaded img would be something like <img src="http://www.google.com/talk/service/badge/Show?encrypted_acount_id_here" /> Once this image has loaded, it loads one of the following images "http://www.google.com/talk/service/resources/offlinef.gif" "http://www.google.com/talk/service/resources/idlef.gif" "http://www.google.com/talk/service/resources/onlinef.gif" Hopefully this make sense now. Thanks heaps

  • Error when instantiating .NET/COM interop class via classic ASP

    - by Lee D
    Hi all, I am having a problem when trying to instantiate a C# .NET class that's been exposed to COM in a classic ASP application. I've used tlbexp to generate a typelib and registered it in Component Services; now when trying to create the object as such: Server.CreateObject("The.Class.Name") I am getting the error: Server object error 'ASP 0177 : 80131534' Server.CreateObject Failed I've searched around online for information on this error, and found numerous discussions but no solution. The error code 0x80131534 apparently means "COR_E_TYPEINITIALIZATION, a type failed to initialize", which would suggest the problem would be in the constructor. The constructor of the class in question sets a private field to an instance of another class from the same assembly, and then reads some configuration settings from an XML file. This behaviour is unit tested and I've checked that the file exists; I can't see anything else that could be breaking in there. A few other points which may or may not be of use: A test .NET project referencing the DLL can instantiate the class just fine; however a test VB6 project referencing the TLB blows up with the same error. Both the DLL and the TLB are in the same location. This application is running locally, on Windows XP Professional SP3 and IIS 5.1. The .NET assembly is built with .NET Framework 2.0, although 3.5 is installed on the machine. I know other people who don't get this error on their builds, so I believe it may be something environmental. Any suggestions are welcome as I've been struggling to fix this for some time. Thanks in advance.

  • Bad Practice requiring file within a model?

    - by Lee Marshall
    I have built an MVC php application and was wondering, if instead of having to write out a large amount of html and set the data, could I not just have all this html (with some php) in a separate file and just require it? For example: $test = '<div> Test content <div>More content</div> </div>'; $APP->Template->setData('test', $test, FALSE); Instead could I not just use: $test = require("includes/content.php"); $APP->Template->setData('test', $test, FALSE); Would this be considered as bad practise? It just seems that by requiring files, it can shorten the length of controllers. Would be good to get anybodies advice on this matter.

  • Execute remote Lua Script

    - by Bruno Lee
    Hi, I want to make an application that executes a remote script. The user can create a script (probabily a LUA script) then stores it in the server. Then he can uses an API for execute the script. I was thinking that API could be a webservice. So my questions are: I need high performance to execute the script. So my first choice was LUA script. Someone has another sugestion? Cause I need high perfomance, I was thinking if the webservice is the best solution. Maybe I could create a TCP/IP Windows Service that hold the users request. It is important to say that I will have many user executing scripts at the same time. So I will have a concurrency problem. My scripts will query in a database. I will use Tokyo Cabinet or Tokio Tyrant. I think Tokio Tyrant is the only solution cause I will have many requests. For perfomance, Do I need to make a connection pooling? Is there anyway to share variables between webservices requests? To make the webservice or the Windows service i was thinking to use C++. Can someone help with these questions? thanks

  • ie8 playing funny with list-style-position: inside

    - by Lee
    Ok, So problem here... when using list-style-position:inside in IE8 the first like is indented but every line after that is not. So the new lines appear under the bullet. This is fine, but when I use a list with that css applied with an a tag within the li then the text automatically gets pushed to the second line, and the first line is empty. When I remove the a tag from the li then it jumps back up. Any idea on why this might be or is this a bug in the ie8 world or do I just need to double check my css? Any insights would be much appreciated.

  • Problem with socket communication between C# and Flex

    - by Chris Lee
    Hi all, I am implementing a simulated b/s stock data system. I am using flex and c# for client and server sides. I found flash has a security policy and I handled the policy-file-request in my server code. But seems it doesn't work, because the code jumped out at "socket.Receive(b)" after connection. I've tried sending message on client in the connection handler, in that case the server can receive correct message. But the auto-generated "policy-file-request" can never be received, and the client can get no data sending from server. Here I put my code snippet. my ActionScript code: public class StockClient extends Sprite { private var hostName:String = "192.168.84.103"; private var port:uint = 55555; private var socket:XMLSocket; public function StockClient() { socket = new XMLSocket(); configureListeners(socket); socket.connect(hostName, port); } public function send(data:Object) : void{ socket.send(data); } private function configureListeners(dispatcher:IEventDispatcher):void { dispatcher.addEventListener(Event.CLOSE, closeHandler); dispatcher.addEventListener(Event.CONNECT, connectHandler); dispatcher.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler); dispatcher.addEventListener(ProgressEvent.PROGRESS, progressHandler); dispatcher.addEventListener(SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler); dispatcher.addEventListener(ProgressEvent.SOCKET_DATA, dataHandler); } private function closeHandler(event:Event):void { trace("closeHandler: " + event); } private function connectHandler(event:Event):void { trace("connectHandler: " + event); //following testing message can be received, but client can't invoke data handler //send("<policy-file-request/>"); } private function dataHandler(event:ProgressEvent):void { //never fired trace("dataHandler: " + event); } private function ioErrorHandler(event:IOErrorEvent):void { trace("ioErrorHandler: " + event); } private function progressHandler(event:ProgressEvent):void { trace("progressHandler loaded:" + event.bytesLoaded + " total: " + event.bytesTotal); } private function securityErrorHandler(event:SecurityErrorEvent):void { trace("securityErrorHandler: " + event); } } my C# code: const int PORT_NUMBER = 55555; const String BEGIN_REQUEST = "begin"; const String END_REQUEST = "end"; const String POLICY_REQUEST = "<policy-file-request/>\u0000"; const String POLICY_FILE = "<?xml version=\"1.0\"?>\n" + "<!DOCTYPE cross-domain-policy SYSTEM \"http://www.adobe.com/xml/dtds/cross-domain-policy.dtd\">\n" + "<cross-domain-policy> \n" + " <allow-access-from domain=\"*\" to-ports=\"55555\"/> \n" + "</cross-domain-policy>\u0000"; ................ private void startListening() { provider = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); provider.Bind(new IPEndPoint(IPAddress.Parse("192.168.84.103"), PORT_NUMBER)); provider.Listen(10); isListened = true; while (isListened) { Socket socket = provider.Accept(); Console.WriteLine("connect!"); byte[] b = new byte[1024]; int receiveLength = 0; try { // code jump out at this statement receiveLength = socket.Receive(b); } catch (Exception e) { Debug.WriteLine(e.ToString()); } String request = System.Text.Encoding.UTF8.GetString(b, 0, receiveLength); Console.WriteLine("request:"+request); if (request == POLICY_REQUEST) { socket.Send(Encoding.UTF8.GetBytes(POLICY_FILE)); Console.WriteLine("response:" + POLICY_FILE); } else if (request == END_REQUEST) { Dispose(socket); } else { StartSocket(socket); break; } } } Sorry for the long code, please someone help with it, thanks a million

  • (PL/SQL)Oracle stored procedure parameter size limit(VARCHAR2)

I know that VARCHAR2 type can contain 32KB in PL/SQL. But, in my test, VARCHAR2 parameter contains only 200 Bytes. What's wrong with this situation? This procedure will called by java daemon program. So, There's no declaration of parameters size before calling procedure. Thanks in advance for your reply.

  • Help needed with AES between Java and Objective-C (iPhone)....

    - by Simon Lee
    I am encrypting a string in objective-c and also encrypting the same string in Java using AES and am seeing some strange issues. The first part of the result matches up to a certain point but then it is different, hence when i go to decode the result from Java onto the iPhone it cant decrypt it. I am using a source string of "Now then and what is this nonsense all about. Do you know?" Using a key of "1234567890123456" The objective-c code to encrypt is the following: NOTE: it is a NSData category so assume that the method is called on an NSData object so 'self' contains the byte data to encrypt. - (NSData *)AESEncryptWithKey:(NSString *)key { char keyPtr[kCCKeySizeAES128+1]; // room for terminator (unused) bzero(keyPtr, sizeof(keyPtr)); // fill with zeroes (for padding) // fetch key data [key getCString:keyPtr maxLength:sizeof(keyPtr) encoding:NSUTF8StringEncoding]; NSUInteger dataLength = [self length]; //See the doc: For block ciphers, the output size will always be less than or //equal to the input size plus the size of one block. //That's why we need to add the size of one block here size_t bufferSize = dataLength + kCCBlockSizeAES128; void *buffer = malloc(bufferSize); size_t numBytesEncrypted = 0; CCCryptorStatus cryptStatus = CCCrypt(kCCEncrypt, kCCAlgorithmAES128, kCCOptionPKCS7Padding, keyPtr, kCCKeySizeAES128, NULL /* initialization vector (optional) */, [self bytes], dataLength, /* input */ buffer, bufferSize, /* output */ &numBytesEncrypted); if (cryptStatus == kCCSuccess) { //the returned NSData takes ownership of the buffer and will free it on deallocation return [NSData dataWithBytesNoCopy:buffer length:numBytesEncrypted]; } free(buffer); //free the buffer; return nil; } And the java encryption code is... public byte[] encryptData(byte[] data, String key) { byte[] encrypted = null; Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider()); byte[] keyBytes = key.getBytes(); SecretKeySpec keySpec = new SecretKeySpec(keyBytes, "AES"); try { Cipher cipher = Cipher.getInstance("AES/ECB/PKCS7Padding", "BC"); cipher.init(Cipher.ENCRYPT_MODE, keySpec); encrypted = new byte[cipher.getOutputSize(data.length)]; int ctLength = cipher.update(data, 0, data.length, encrypted, 0); ctLength += cipher.doFinal(encrypted, ctLength); } catch (Exception e) { logger.log(Level.SEVERE, e.getMessage()); } finally { return encrypted; } } The hex output of the objective-c code is - 7a68ea36 8288c73d f7c45d8d 22432577 9693920a 4fae38b2 2e4bdcef 9aeb8afe 69394f3e 1eb62fa7 74da2b5c 8d7b3c89 a295d306 f1f90349 6899ac34 63a6efa0 and the java output is - 7a68ea36 8288c73d f7c45d8d 22432577 e66b32f9 772b6679 d7c0cb69 037b8740 883f8211 748229f4 723984beb 50b5aea1 f17594c9 fad2d05e e0926805 572156d As you can see everything is fine up to - 7a68ea36 8288c73d f7c45d8d 22432577 I am guessing I have some of the settings different but can't work out what, I tried changing between ECB and CBC on the java side and it had no effect. Can anyone help!? please....

  • Do I need the bin\debug\appName.vshost.exe and appName.vshost.manifest in my SVN code repository?

    - by Bruce Lee
    I am building an application which is based on a sample application, written in C# on .NET 2, and is built on VS2008. This application is mostly a wrapper for a COM application. However I compile it in .NET 3.5. The sample application came with the following files in it's bin\debug: appName.vshost.exe appName.vshost.exe.manifest I noticed that I can delete the files and VS re-builds vshost.exe, and the vshost.manifest file appears with modification date the same as the deleted file as if VS has copied in from somewhere. My question is, should I put this files in my SVN code repository?

    Hey all I am going through the pain stacking process of sorting out someone else code. So I am decided to recreate a new database to sit alongside the old one then to use triggers to transfer data between both tables.

Once one updates it should update the other but as both tables have triggers it just will loop which will cause an issue. Is their a way to stop this from happening ? Hope this makes sense and hope you can advise.

  • Program Structure Design Tools? (Top Down Design)

    - by Lee Olayvar
    I have been looking to expand my methodologies to better involve Unit testing, and i stumbled upon Behavioral Driven Design (Namely Cucumber, and a few others). I am quite intrigued by the concept as i have never been able to properly design top down, only because keeping track of the design gets lost without a decent way to record it. So on that note, in a mostly language agnostic way, are there any useful tools out there i am (probably) unaware of? Eg, i have often been tempted to try building flow charts for my programs, but i am not sure how much that will help, and it seems a bit confusing to me how i could make a complex enough flow chart to handle the logic of a full program, and all its features.. ie, it just seems like flow charts would be limiting in the design scheme.. or possibly grow to an unmaintainable scale. BDD methods are nice, but with a system that is so tied to structure, tying into the language and unit testing seems like a must (for it to be worth it) and it seems to be hard to find something to work well with both Python and Java (my two main languages). So anyway.. on that note, any comments are much appreciated. I have searched around on here and it seems like top down design is a well discussed topic, but i haven't seen too much reference to tools themselves, eg, flow chart programs, etc. I am on Linux, if it matters (in the case of programs).

  • [Struts2+tiles] How can I make title dynamically?

    - by Lee Domin
    I'm developing BBS in struts2 and tiles(2) framework. I want to push a value in ActionSupport class and pop the value in layout.jsp of tiles. but i just keep failing to access to the value. I will explain my works step by step. 1) Users click a link to view an article at list page. And BoardView class will be called as defined in struts.xml --list.jsp-- <a href="view_board?num=${num}"> ${ subject } </a> --struts.xml-- <action name="View_board" class="board.BoardView"> <result type="tiles">board.view</result> </action> 2)Action class will put title into the value stack... right? --BoardView class-- public class BoardView extends ActionSupport private String title; public void Execute() throws Exception { ... setTitle(board.getSubject()); return SUCCESS; } ... (setter and getter of title) 3) As ActionClass returns SUCCESS, it will go to tiles definition named board.view --struts.xml-- <action name="View_board" class="board.BoardView"> <result type="tiles">board.view</result> </action> 4)Here's the tiles-def.xml and the problem. I think the value of 'title' can't be popped from value stack. ==tiles-def.xml== <definition name="board.view" extends="layout"> <put-attribute name="title" value="%title" /> <put-attribute name="body" value="/board/view.jsp" /> </definition> (I can't indent with tags... sorry) Here's the layout.jsp ==layout.jsp== ... <title><tiles:getAsString name="title" /></title> ... I tried to replace the value attribute to %{title}, $title and ${title}. But nothings worked out. Web Browser just shows the string itself($title). I don't know what to do... please help me. I hope you all understand my works despite of my bad explanation.
