  • C# Julian Date Parser

    - by Jake Pearson
    I have a cell in a spreadsheet that is a date object in Excel but becomes a double (something like 39820.0 for 1/7/2009) when it comes out of C1's xls class. I read this is a Julian date format. Can someone tell me how to parse it back into a DateTime in C#? Update: It looks like I might not have a Julian date, but instead the number of days since Dec 30, 1899.

  • JSON.parse string with quotes

    - by mjsilva
    Hi, I've this: JSON.parse('{"130.00000001":{"p_cod":"130.00000001","value":"130.00000001 HDD Upgrade to 2x 250GB HDD 2.5\" SATA2 7200rpm"}}'); http://www.jsonlint.com/ says it's perfectly valid json. But on execution I have a JSON.parse error. But, if I change my code to: JSON.parse('{"130.00000001":{"p_cod":"130.00000001","value":"130.00000001 HDD Upgrade to 2x 250GB HDD 2.5\\" SATA2 7200rpm"}}'); (note the double backslash) It works, but now jsonlint gives me invalid json :/ Can someone help to understand this behavior?

  • Remove a line from a csv file bash, sed, bash

    - by S1syphus
    I'm looking for a way to remove lines within multiple csv files, in bash using sed, awk or anything appropriate where the file ends in 0. So there are multiple csv files, their format is: EXAMPLEfoo,60,6 EXAMPLEbar,30,10 EXAMPLElong,60,0 EXAMPLEcon,120,6 EXAMPLEdev,60,0 EXAMPLErandom,30,6 So the file will be amended to: EXAMPLEfoo,60,6 EXAMPLEbar,30,10 EXAMPLEcon,120,6 EXAMPLErandom,30,6 A problem which I can see arising is distinguishing between double digits that end in zero and 0 itself. So any ideas?

  • Apache Commons FileUpload Does not behave like expected

    - by Harry Pham
    I just want to assure you guys that before I post this, I have read couple of similar post but none solved my problem. So here it is. I use Ajax taglib for my form since it wont refresh my screen <%@ taglib uri="WEB-INF/taglib.tld" prefix="a" %> <a:AjaxUpload action="UploadServlet"> <input type="file"> <input type="submit" value="Upload"> </a:AjaxUpload> If this is in any confused you guys, then you can think of the above code will create these form, but send request asynchronously. <form action="UploadServlet" enctype="multipart/form-data" method="post"> <input type="file"> <input type="submit"> </form> My first question is, if I add name="file" inside the <input> to make it become like this, <input type="file" name="file">, my servlet will throw an exception. It wont if I take it out. Here is the exception: SEVERE: Servlet.service() for servlet UploadServlet threw exception javax.servlet.ServletException: Servlet execution threw an exception at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:313) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:298) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:852) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:588) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) at java.lang.Thread.run(Thread.java:637) My second question is: On the server side, I check the request to see if it is isMultipartContent, and it is. But then when I parseRequest() and store into List<FileItem> items, the items.size() is 0. Here is my Servlet code FileItemFactory factory = new DiskFileItemFactory(); ServletFileUpload upload = new ServletFileUpload(factory); List<FileItem> items = null; if(request.getContentType() != null && request.getContentType().toLowerCase().indexOf("multipart/form-data") > -1){ if(upload.isMultipartContent(request)){ items = upload.parseRequest(request); //It got to here, but items.size is 0. why????????????? } }

  • QueryInterface fails at casting inside COM-interface implementation

    - by brecht
    I am creating a tool in c# to retrieve messages of a CAN-network (network in a car) using an Dll written in C/C++. This dll is usable as a COM-interface. My c#-formclass implements one of these COM-interfaces. And other variables are instantiated using these COM-interfaces (everything works perfect). The problem: The interface my C#-form implements has 3 abstract functions. One of these functions is called -by the dll- and i need to implement it myself. In this function i wish to retrieve a property of a form-wide variable that is of a COM-type. The COM library is CANSUPPORTLib The form-wide variable: private CANSUPPORTLib.ICanIOEx devices = new CANSUPPORTLib.CanIO(); This variable is also form-wide and is retrieved via the devices-variable: canreceiver = (CANSUPPORTLib.IDirectCAN2)devices.get_DirectDispatch(receiverLogicalChannel); The function that is called by the dll and implemented in c# public void Message(double dTimeStamp) { Console.WriteLine("!!! message ontvangen !!!" + Environment.NewLine); try { CANSUPPORTLib.can_msg_tag message = new CANSUPPORTLib.can_msg_tag(); message = (CANSUPPORTLib.can_msg_tag) System.Runtime.InteropServices.Marshal.PtrToStructure(canreceiver.RawMessage, message.GetType()); for (int i = 0; i < message.data.Length; i++) { Console.WriteLine("byte " + i + ": " + message.data[i]); } } catch (Exception e) { Console.WriteLine(e.Message); } } The error rises at this line: message = (CANSUPPORTLib.can_msg_tag)System.Runtime.InteropServices.Marshal.PtrToStructure(canreceiver.RawMessage, message.GetType()); Error: Unable to cast COM object of type 'System.__ComObject' to interface type 'CANSUPPORTLib.IDirectCAN2'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{33373EFC-DB42-48C4-A719-3730B7F228B5}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)). Notes: It is possible to have a timer-clock that checks every 100ms for the message i need. The message is then retrieved in the exact same way as i do now. This timer is started when the form starts. The checking is only done when Message(double) has put a variable to true (a message arrived). When the timer-clock is started in the Message function, i have the same error as above Starting another thread when the form starts, is also not possible. Is there someone with experience with COM-interop ? When this timer

  • Convert Plain Text Hyperlinks into HTML Hyperlinks in PHP

    - by Volomike
    I have a simple commenting system here... http://affbuzz.com/comments/7299a55137def55917a5dc6c4fe0f261af8a4217 ...and people can submit hyperlinks inside the plain text field. When I display these records back from the database and into the web page, what RegExp in PHP can I use to convert these links into HTML-type anchor links? Bonus: For the algorithm to not do this with any other kind of link, just http and https.

  • Zend Framework + Uplodify Flash Uploader Troubles

    - by Richard Knop
    I've been trying to get the Uploadify flash uploader (www.uploadify.com) to work with Zend Framework, with no success so far. I have placed all Uploadify files under /public/flash-uploader directory. In the controller I include all required files and libraries like this: $this->view->headScript()->appendFile('/js/jquery-1.3.2.min.js'); $this->view->headLink()->appendStylesheet('/flash-uploader/css/default.css'); $this->view->headLink()->appendStylesheet('/flash-uploader/css/uploadify.css'); $this->view->headScript()->appendFile('/flash-uploader/scripts/swfobject.js'); $this->view->headScript()->appendFile('/flash-uploader/scripts/jquery.uploadify.v2.1.0.min.js'); And then I activate the plugin like this (#photo is id of the input file field): $(document).ready(function() { $("#photo").uploadify({ 'uploader' : '/flash-uploader/scripts/uploadify.swf', 'script' : 'my-account/flash-upload', 'cancelImg' : '/flash-uploader/cancel.png', 'folder' : 'uploads/tmp', 'queueID' : 'fileQueue', 'auto' : true, 'multi' : true, 'sizeLimit' : 2097152 }); }); As you can see I am targeting the my-account/flash-upload script as a backend processing (my-account is a controller, flash-upload is an action). My form markup looks like this: <form enctype="multipart/form-data" method="post" action="/my-account/upload-public-photo"><ol> <li><label for="photo" class="optional">File Queue<div id="fileQueue"></div></label> <input type="hidden" name="MAX_FILE_SIZE" value="31457280" id="MAX_FILE_SIZE" /> <input type="file" name="photo" id="photo" class="input-file" /></li> <li><div class="button"> <input type="submit" name="upload_public_photo" id="upload_public_photo" value="Save" class="input-submit" /></div></li></ol></form> And yet it's not working. The browse button doesn't even show up as in the demo page, I get only a regular input file field. Any ideas where could the problem be? I've already been staring into the code for hours and I cannot see any mistake anywhere and I'm starting to be exhausted after going through the same 30 lines of code 30 times in a row.

  • Improving lossless codecs [closed]

    - by LarsOn
    Improve the name to match positively Starting just discussing the naming first ignoring tech details, lossless is a negative and double negative word for one good reason should get named more appropriate: Lossless also matches nothing. When naming like all intact or likewise matches something in a manner more physical like sounds are. Then more technically stated that a copy might contain more information than the original. Does method as such have a name, if so what do I refer to, can we name it if you please or just discuss related handling.

    I am adding an Excel Worksheet object inside Word. Excel has a COM addin attached to it. Any idea how one can know whether Excel is running independently or as an embedded object? The COM Addin attached to Excel loads when the embedded Excel object is activated (double-clicked) inside Word. I am looking for some kind of a property or a parameter in OnConnection(...) or other method that can tell the state of Excel object.

  • Xcode - some variables don't show

    - by Mike
    This picture shows a debugging session. "lista" is a NSMutableArray containing, in this case, two elements: 0 and 1. Each element's content is seen on the debugging window as {(unichar *)Xcode_CFStringSummary($VAR, $ID)}:s but if I double click on any element, its value shows on a pop up window. Why is the values don't showing directly? How to force Xcode to show the values instead of this stupid and useless "{(unichar *)Xcode_CFStringSummary($VAR, $ID)}:s" ? thanks for any help.
