  • MS Access Crashed an now all Form objects and code modules are missing

    - by owlie
    I was adding a form to our Access 07 db. I copied an existing form to use as a template, renamed it, and saved it. I opened a different form to check something and Access crashed. When I reopened the database it says: "Access has detected that this database is in an inconsistent state, and will attempt to recover the database." etc. When it reopened - all forms and reports were missing. Saved queries remain. The error message states that object recovery failures will be noted in a Recovery Errors table - but this table wasn't created. The links to the be database remained intact. The database is split - I was experimenting with a form on a front-end copy which might have something to do with it. Any ideas what would cause this (I can see loosing recent work - but nixing all form objects?!) And is there any chance of recovery?

  • Windows Form Components Access

    - by rxm0203
    What is the best way to access components (e.g. imagelist, timer) from a form instance? I am working on multi form windows forms application on .NET Compact Framework version 3.5 SP1 with C#. I have a Controller class associated with each form for MVC implementation. Here is my sample Controller class. public class Controller { public void Init(Form f) { //f.Controls will allow access to all controls //How shall I access imagelist, timer on form f. } } My question is how can I access non visual components without taking a performance hit of reflection? Any code snippets are welcome. If reflection is only way, then can you provide me optimal way for components access please? Thanks,

  • Submit form without page reloading

    - by Camran
    I have a classifieds website, and on the page where ads are showed, I am creating a "Send a tip to a friend" form... So anybody who wants can send a tip of the ad to some friends email-adress. I am guessing the form must be submitted to a php page right? <form name='tip' method='post' action='tip.php'> Tip somebody: <input name="tip_email" type="text" size="30" onfocus="tip_div(1);" onblur="tip_div(2);"/> <input type="submit" value="Skicka Tips"/> <input type="hidden" name="ad_id" /> </form> When submitting the form, the page gets reloaded... I don't want that... Is there any way to make it not reload and still send the mail? Preferrably without ajax or jquery... Thanks

  • Setting a form field's valule during validation

    - by LaundroMat
    Hi, I read about this issue already, but I'm having trouble understanding why I can't change the value of a form's field during validation. I have a form where a user can enter a decimal value. This value has to be higher than the initial value of the item the user is changing. During clean(), the value that was entered is checked against the item's previous value. I would like to be able to re-set the form field's value to the item's initial value when a user enters a lower value. Is this possible from within the clean() method, or am I forced to do this in the view? Somehow, it doesn't feel right to do this in the view... (To make matters more complicated, the form's fields are built up dynamically, meaning I have to override the form's clean() method instead of using the clean_() method). Thanks in advance!

  • Contact Form + jQuery validationengine

SlideUp (). FadeOut () so that the sending of this email appears for 3 seconds "$ (" # form_send "). addClass ('hide')" before you do anything else then the form disappears up using some second type slideUp "$ (" # form_box "). addClass ('hide')" by displaying just the "$ (" # form_success "). removeClass ('hide')" in the address bar also appears the form data (e.g. ../index.php?name=test&email=example%40mail.com&website=&message=helloworld)

  • WCF GZip Compression Request/Response Processing

    - by IanT8
    How do I get a WCF client to process server responses which have been GZipped or Deflated by IIS? On IIS, I've followed the instructions here on how to make IIS 6 gzip all responses (where the request contained "Accept-Encoding: gzip, deflate") emitted by .svc wcf services. On the client, I've followed the instructions here and here on how to inject this header into the web request: "Accept-Encoding: gzip, deflate". Fiddler2 shows the response is binary and not plain old Xml. The client crashes with an exception which basically says there's no Xml header, which ofcourse is true. In my IClientMessageInspector, the app crashes before AfterReceiveReply is called. Some further notes: (1) I can't change the WCF service or client as they are supplied by a 3rd party. I can however attach behaviors and/or message inspectors via configuration if this is the right direction to take. (2) I don't want to compress/uncompress just the soap body, but the entire message. Any ideas/solutions? * SOLVED * It was not possible to write a WCF extension to achieve these goals. Instead I followed this CodeProject article which advocate a helper class: public class CompressibleHttpRequestCreator : IWebRequestCreate { public CompressibleHttpRequestCreator() { } WebRequest IWebRequestCreate.Create(Uri uri) { HttpWebRequest httpWebRequest = Activator.CreateInstance(typeof(HttpWebRequest), BindingFlags.CreateInstance | BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance, null, new object[] { uri, null }, null) as HttpWebRequest; if (httpWebRequest == null) { return null; } httpWebRequest.AutomaticDecompression =DecompressionMethods.GZip | DecompressionMethods.Deflate; return httpWebRequest; } } and also, an addition to the application configuration file: <configuration> <system.net> <webRequestModules> <remove prefix="http:"/> <add prefix="http:" type="Pajocomo.Net.CompressibleHttpRequestCreator, Pajocomo" /> </webRequestModules> </system.net> </configuration> What seems to be happening is that WCF eventually asks some factory or other deep down in system.net to provide an HttpWebRequest instance, and we provide the helper that will be asked to create the required instance. In the WCF client configuration file, a simple basicHttpBinding is all that is required, without the need for any custom extensions. When the application runs, the client Http request contains the header "Accept-Encoding: gzip, deflate", the server returns a gzipped web response, and the client transparently decompresses the http response before handing it over to WCF. When I tried to apply this technique to Web Services I found that it did NOT work. Although the helper class was executed in the same was as when used by the WCF client, the http request did not contain the "Accept-Encoding: ..." header. To make this work for Web Services, I had to edit the Web Proxy class, and add this method: protected override System.Net.WebRequest GetWebRequest(Uri uri) { System.Net.HttpWebRequest rq = (System.Net.HttpWebRequest)base.GetWebRequest(uri); rq.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate; return rq; } Note that it did not matter whether the CompressibleHttpRequestCreator and block from the application config file were present or not. For web services, only overriding GetWebRequest in the Web Service Proxy worked.

  • ASP.NET MVC 2 - Html.DropDownList not working in an AJAX form

    - by Jacob
    I am trying to create an MVC 2 solution and I have run into the following problem: Index.aspx: <% using(Ajax.BeginForm("Forms", new AjaxOptions{UpdateTargetId="form", HttpMethod="POST"})) { %> <h3>Input: </h3> <p><%= Html.DropDownList("dropDown")%> <input type="submit" value="Select Mission" /></p> <% } %> HomeController.cs: public ActionResult Index() { var list = new [] { "item1", "item2", "item3" }; ViewData["dropDown"] = new SelectList(list); return View(); } public ActionResult Forms(string dropDown) { if (dropDown == null || dropDown == "") ViewData["txt"] = "Ahhh..."; else ViewData["txt"] = "You entered: " + dropDown; return PartialView("Form", dropDown); } Form.ascx: <%: ViewData["txt"] % This does not work. However, the whole thing does work if I use an Html.TextBox instead. For example: <div id="form"> <% using(Ajax.BeginForm("Forms", new AjaxOptions{UpdateTargetId="form", HttpMethod="POST"})) { %> <h3>Input: </h3> <%= Html.TextBox("textBox") %> <input type="submit" value="Select Mission" /></p> <% } %> </div> (and refactor the method in the controller so that it's argument is textBox instead of dropDown). My question is why does the AJAX form work for an Html.TextBox, but not for an Html.DropDownList, or what am I doing wrong? My only idea is that maybe the argument in the controller is not supposed to be of type string when using a DropDownList, but this is really just a guess. Thanks in advance.

  • jQuery tabs: Post previously selected tab when opening a new one

    - by Bjorn Thor Jonsson
    Hi Having two forms, each in it's own jQuery UI tab, how can I post the form in the deselected tab when clicking a new tab? This I need to do to maintain state at the server side when the user navigates between tabs. I have looked into something like $('#tab-container-id').bind('tabsselect', function(event, ui) { ... }); but haven't found a way to get to the tab being hidden and post it's form contents. One way to set this up would be to enclose the whole tab set inside a form element that would be submitted whenever a tab is selected but I would rather have a form inside each tab, each with it's own action (that gets bound to different Spring MVC command objects). Thanks for any hints...

  • jQuery DataTables server side processing and ASP.Net

    - by Chad
    I'm trying to use the server side functionality of the jQuery Datatables plugin with ASP.Net. The ajax request is returning valid JSON, but nothing is showing up in the table. I originally had problems with the data I was sending in the ajax request. I was getting a "Invalid JSON primative" error. I discovered that the data needs to be in a string instead of JSON serialized, as described in this post: http://encosia.com/2008/06/05/3-mistakes-to-avoid-when-using-jquery-with-aspnet-ajax/. I wasn't quite sure how to fix that, so I tried adding this in the ajax request: "data": "{'sEcho': '" + aoData.sEcho + "'}" If the aboves eventually works I'll add the other parameters later. Right now I'm just trying to get something to show up in my table. The returning JSON looks ok and validates, but the sEcho in the post is undefined, and I think thats why no data is being loaded into the table. So, what am I doing wrong? Am I even on the right track or am I being stupid? Does anyone ran into this before or have any suggestions? Here's my jQuery: $(document).ready(function() { $("#grid").dataTable({ "bJQueryUI": true, "sPaginationType": "full_numbers", "bServerSide":true, "sAjaxSource": "GridTest.asmx/ServerSideTest", "fnServerData": function(sSource, aoData, fnCallback) { $.ajax({ "type": "POST", "dataType": 'json', "contentType": "application/json; charset=utf-8", "url": sSource, "data": "{'sEcho': '" + aoData.sEcho + "'}", "success": fnCallback }); } }); }); HTML: <table id="grid"> <thead> <tr> <th>Last Name</th> <th>First Name</th> <th>UserID</th> </tr> </thead> <tbody> <tr> <td colspan="5" class="dataTables_empty">Loading data from server</td> </tr> </tbody> </table> Webmethod: <WebMethod()> _ Public Function ServerSideTest() As Data Dim list As New List(Of String) list.Add("testing") list.Add("chad") list.Add("testing") Dim container As New List(Of List(Of String)) container.Add(list) list = New List(Of String) list.Add("testing2") list.Add("chad") list.Add("testing") container.Add(list) HttpContext.Current.Response.ContentType = "application/json" Return New Data(HttpContext.Current.Request("sEcho"), 2, 2, container) End Function Public Class Data Private _iTotalRecords As Integer Private _iTotalDisplayRecords As Integer Private _sEcho As Integer Private _sColumns As String Private _aaData As List(Of List(Of String)) Public Property sEcho() As Integer Get Return _sEcho End Get Set(ByVal value As Integer) _sEcho = value End Set End Property Public Property iTotalRecords() As Integer Get Return _iTotalRecords End Get Set(ByVal value As Integer) _iTotalRecords = value End Set End Property Public Property iTotalDisplayRecords() As Integer Get Return _iTotalDisplayRecords End Get Set(ByVal value As Integer) _iTotalDisplayRecords = value End Set End Property Public Property aaData() As List(Of List(Of String)) Get Return _aaData End Get Set(ByVal value As List(Of List(Of String))) _aaData = value End Set End Property Public Sub New(ByVal sEcho As Integer, ByVal iTotalRecords As Integer, ByVal iTotalDisplayRecords As Integer, ByVal aaData As List(Of List(Of String))) If sEcho <> 0 Then Me.sEcho = sEcho Me.iTotalRecords = iTotalRecords Me.iTotalDisplayRecords = iTotalDisplayRecords Me.aaData = aaData End Sub Returned JSON: {"__type":"Data","sEcho":0,"iTotalRecords":2,"iTotalDisplayRecords":2,"aaData":[["testing","chad","testing"],["testing2","chad","testing"]]}

  • iPhone Image Processing--matrix convolution

    - by James
    I am implementing a matrix convolution blur on the iPhone. The following code converts the UIImage supplied as an argument of the blur function into a CGImageRef, and then stores the RGBA values in a standard C char array. CGImageRef imageRef = imgRef.CGImage; int width = imgRef.size.width; int height = imgRef.size.height; CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); unsigned char *pixels = malloc((height) * (width) * 4); NSUInteger bytesPerPixel = 4; NSUInteger bytesPerRow = bytesPerPixel * (width); NSUInteger bitsPerComponent = 8; CGContextRef context = CGBitmapContextCreate(pixels, width, height, bitsPerComponent, bytesPerRow, colorSpace, kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big); CGContextDrawImage(context, CGRectMake(0, 0, width, height), imageRef); CGContextRelease(context); Then the pixels values stored in the pixels array are convolved, and stored in another array. unsigned char *results = malloc((height) * (width) * 4); Finally, these augmented pixel values are changed back into a CGImageRef, converted to a UIImage, and the returned at the end of the function with the following code. context = CGBitmapContextCreate(results, width, height, bitsPerComponent, bytesPerRow, colorSpace, kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big); CGImageRef finalImage = CGBitmapContextCreateImage(context); UIImage *newImage = [UIImage imageWithCGImage:CGBitmapContextCreateImage(context)]; CGImageRelease(finalImage); NSLog(@"edges found"); free(results); free(pixels); CGColorSpaceRelease(colorSpace); return newImage; This works perfectly, once. Then, once the image is put through the filter again, very odd, unprecedented pixel values representing input pixel values that don't exist, are returned. Is there any reason why this should work the first time, but then not afterward? Beneath is the entirety of the function. -(UIImage*) blur:(UIImage*)imgRef { CGImageRef imageRef = imgRef.CGImage; int width = imgRef.size.width; int height = imgRef.size.height; CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); unsigned char *pixels = malloc((height) * (width) * 4); NSUInteger bytesPerPixel = 4; NSUInteger bytesPerRow = bytesPerPixel * (width); NSUInteger bitsPerComponent = 8; CGContextRef context = CGBitmapContextCreate(pixels, width, height, bitsPerComponent, bytesPerRow, colorSpace, kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big); CGContextDrawImage(context, CGRectMake(0, 0, width, height), imageRef); CGContextRelease(context); height = imgRef.size.height; width = imgRef.size.width; float matrix[] = {0,0,0,0,1,0,0,0,0}; float divisor = 1; float shift = 0; unsigned char *results = malloc((height) * (width) * 4); for(int y = 1; y < height; y++){ for(int x = 1; x < width; x++){ float red = 0; float green = 0; float blue = 0; int multiplier=1; if(y>0 && x>0){ int index = (y-1)*width + x; red = matrix[0]*multiplier*(float)pixels[4*(index-1)] + matrix[1]*multiplier*(float)pixels[4*(index)] + matrix[2]*multiplier*(float)pixels[4*(index+1)]; green = matrix[0]*multiplier*(float)pixels[4*(index-1)+1] + matrix[1]*multiplier*(float)pixels[4*(index)+1] + matrix[2]*multiplier*(float)pixels[4*(index+1)+1]; blue = matrix[0]*multiplier*(float)pixels[4*(index-1)+2] + matrix[1]*multiplier*(float)pixels[4*(index)+2] + matrix[2]*multiplier*(float)pixels[4*(index+1)+2]; index = (y)*width + x; red = red+ matrix[3]*multiplier*(float)pixels[4*(index-1)] + matrix[4]*multiplier*(float)pixels[4*(index)] + matrix[5]*multiplier*(float)pixels[4*(index+1)]; green = green + matrix[3]*multiplier*(float)pixels[4*(index-1)+1] + matrix[4]*multiplier*(float)pixels[4*(index)+1] + matrix[5]*multiplier*(float)pixels[4*(index+1)+1]; blue = blue + matrix[3]*multiplier*(float)pixels[4*(index-1)+2] + matrix[4]*multiplier*(float)pixels[4*(index)+2] + matrix[5]*multiplier*(float)pixels[4*(index+1)+2]; index = (y+1)*width + x; red = red+ matrix[6]*multiplier*(float)pixels[4*(index-1)] + matrix[7]*multiplier*(float)pixels[4*(index)] + matrix[8]*multiplier*(float)pixels[4*(index+1)]; green = green + matrix[6]*multiplier*(float)pixels[4*(index-1)+1] + matrix[7]*multiplier*(float)pixels[4*(index)+1] + matrix[8]*multiplier*(float)pixels[4*(index+1)+1]; blue = blue + matrix[6]*multiplier*(float)pixels[4*(index-1)+2] + matrix[7]*multiplier*(float)pixels[4*(index)+2] + matrix[8]*multiplier*(float)pixels[4*(index+1)+2]; red = red/divisor+shift; green = green/divisor+shift; blue = blue/divisor+shift; if(red<0){ red=0; } if(green<0){ green=0; } if(blue<0){ blue=0; } if(red>255){ red=255; } if(green>255){ green=255; } if(blue>255){ blue=255; } int realPos = 4*(y*imgRef.size.width + x); results[realPos] = red; results[realPos + 1] = green; results[realPos + 2] = blue; results[realPos + 3] = 1; }else { int realPos = 4*((y)*(imgRef.size.width) + (x)); results[realPos] = 0; results[realPos + 1] = 0; results[realPos + 2] = 0; results[realPos + 3] = 1; } } } context = CGBitmapContextCreate(results, width, height, bitsPerComponent, bytesPerRow, colorSpace, kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big); CGImageRef finalImage = CGBitmapContextCreateImage(context); UIImage *newImage = [UIImage imageWithCGImage:CGBitmapContextCreateImage(context)]; CGImageRelease(finalImage); free(results); free(pixels); CGColorSpaceRelease(colorSpace); return newImage;} THANKS!!!

  • OperationalError "unable to open database file" processing query results with SQLAlchemy and SQLite3

    - by Peter
    I'm running into this little problem that I hope is just a dumb user error. It looks like some sort of a size limit with a query to a SQLite database. I managed to reproduce the issue with an in-memory DB and a simple script shown below. I can make it work by either reducing the number of records in the DB; or by reducing the size of each record; or by dropping the order_by() call. I am using Python 2.5.5 and SQLAlchemy 0.6.0 in a Cygwin environment. Thanks! #!/usr/bin/python from sqlalchemy.orm import sessionmaker import sqlalchemy import sqlalchemy.orm class Person(object): def __init__(self, name): self.name = name engine = sqlalchemy.create_engine('sqlite:///:memory:') Session = sessionmaker(bind=engine) metadata = sqlalchemy.schema.MetaData(bind=engine) person_table = sqlalchemy.Table('person', metadata, sqlalchemy.Column('id', sqlalchemy.types.Integer, primary_key=True), sqlalchemy.Column('name', sqlalchemy.types.String)) metadata.create_all(engine) sqlalchemy.orm.mapper(Person, person_table) session = Session() session.add_all([Person("012345678901234567890123456789012") for i in range(5000)]) session.commit() persons = session.query(Person).order_by(Person.name).all() print "count =", len(persons) session.close() The all() call to the query result fails with the OperationalError exception: Traceback (most recent call last): File "./stress.py", line 27, in <module> persons = session.query(Person).order_by(Person.name).all() File "/usr/lib/python2.5/site-packages/sqlalchemy/orm/query.py", line 1343, in all return list(self) File "/usr/lib/python2.5/site-packages/sqlalchemy/orm/query.py", line 1451, in __iter__ return self._execute_and_instances(context) File "/usr/lib/python2.5/site-packages/sqlalchemy/orm/query.py", line 1456, in _execute_and_instances mapper=self._mapper_zero_or_none()) File "/usr/lib/python2.5/site-packages/sqlalchemy/orm/session.py", line 737, in execute clause, params or {}) File "/usr/lib/python2.5/site-packages/sqlalchemy/engine/base.py", line 1109, in execute return Connection.executors[c](self, object, multiparams, params) File "/usr/lib/python2.5/site-packages/sqlalchemy/engine/base.py", line 1186, in _execute_clauseelement return self.__execute_context(context) File "/usr/lib/python2.5/site-packages/sqlalchemy/engine/base.py", line 1215, in __execute_context context.parameters[0], context=context) File "/usr/lib/python2.5/site-packages/sqlalchemy/engine/base.py", line 1284, in _cursor_execute self._handle_dbapi_exception(e, statement, parameters, cursor, context) File "/usr/lib/python2.5/site-packages/sqlalchemy/engine/base.py", line 1282, in _cursor_execute self.dialect.do_execute(cursor, statement, parameters, context=context) File "/usr/lib/python2.5/site-packages/sqlalchemy/engine/default.py", line 277, in do_execute cursor.execute(statement, parameters) sqlalchemy.exc.OperationalError: (OperationalError) unable to open database file u'SELECT person.id AS person_id, person.name AS person_name \nFROM person ORDER BY person.name' ()

  • ZendX_JQuery dialogContainer usage

    - by Kalle Johansson
    Hi ! I'm aming to make use of the ZendX_JQuery dialogContainer view helper, in order to produce a modal window, were users can input specified information(for example send a message). I'm trying to use the dialogContainer view helper in this fashion. First of, include the ZendX library in the applications library folder. Secondly, include the following row in the initViewHelper method within the Bootstrap.php file "$view-addHelperPath('ZendX/JQuery/View/Helper/', 'ZendX_JQuery_View_Helper');" third, adding the following conditional enabling of js in the layout.phtml "<?php if($this->jQuery()->isEnabled()){ $this->jQuery()->setLocalPath($this->baseUrl() .'/js/jquery/js/jquery-1.4.2.min.js') ->setUiLocalPath($this->baseUrl() .'/js/jquery/js/jquery-ui-1.8.custom.min.js') ->addStylesheet($this->baseUrl() .'/js/jquery/css/ui-lightness/jquery-ui-1.8.custom.css'); echo $this->jQuery(); } ?>" fourth, creating my Application_Form_JQueryForm extending ZendX_JQuery_Form "<?php class Application_Form_JQueryForm extends ZendX_JQuery_Form { private $form; public function init() { $this->form = $this->setAction(Zend_Controller_Front::getInstance()->getBaseUrl() . '/index/index') ->setMethod('post'); $this->form->setDecorators(array( 'FormElements', 'Form', array ('DialogContainer', array( 'id' => 'tabContainer', 'style' => 'width: 600px;', 'title' => 'Send a private message to Kalle', 'JQueryParams' => array( 'tabPosition' => 'top', ), )), )); $topic = new Zend_Form_Element_Text('topic'); $topic->setValue('topic') ->setRequired(true) ->setValidators(array('validators' => array( 'validator' => 'StringLength', 'options' => array(1,15) ))) ->setDecorators(array( 'ViewHelper', 'Description', 'Errors', array('HtmlTag', array('tag' => 'dl')))); $textarea = new Zend_Form_Element_Textarea('textarea'); $textarea->setValue('post a comment') ->setAttribs(array( 'rows' => 4, 'cols' => 20 )) ->setRequired(true) ->setValidators(array('validators' => array( 'validator' => 'StringLength', 'options' => array(1,15) ))) ->setDecorators(array( 'ViewHelper', 'Description', 'Errors', array('HtmlTag', array('tag' => 'dl')))); $submit = new Zend_Form_Element_Submit('submit'); $submit->setLabel('Send your comment') ->setDecorators(array( 'ViewHelper', 'Description', 'Errors', array('Description', array('escape' => false, 'tag' => 'span')), array('HtmlTag', array('tag' => 'dl')))) ->setDescription('or <a href="/index/index/send/false">Cancel</a>'); $this->form->addElements(array($topic, $textarea, $submit)); } }" This form is then instanciated in the controllers action method, and called in the view. And so to the problem of mine, no matter what i try, in order to for instance set, the width of the dialogContainer or any other parameter (color, css, height, so on and so forth), this being in the JQueryForm's setDecorator part for the form, i can't seem to get any change whatsoever in the resulting modal when called in the view, any help in the proper direction would be greatly appreciated Thanks in advance, Kalle Johansson

  • Natural language processing - Ideas for beginner's projects

    - by Microkernel
    Hi guys, I am a beginner in NLP and NLTK. I am very interested in NLP and hence joined a weekend course on AI in some local institution, which requires me to do a project for completion of the course, and I decided to do it in NLP. The problem is,the instructor is not good at all for this course (According to me she is just a charlatan) (or may not be very interested in teaching as this is her last batch here after which the institute is going to send her out). So I am stuck in a situation where where I got to finish this project in a month to one and half months period, but as a naive person in the field I am feeling it very difficult to comprehend the things required to decide on project. (Also, as I am working full time, I am not finding enough time to dedicate on this). I considered using NLTK toolkit in python for the project for following reasons. (1) Python is famous for ease of use, rapid prototyping and very active community (considering very short span of time I have, and as I am a C programmer by profession, I need a language that I can learn fast and is simple to use). (2) NLTk has good review, and extensive documentation and a very active community. So the problem is what project should I take up, so that I can learn something and will be able to finish project in time. (I know almost nothing in NLP, don't even know what exactly corpora is... :( ) So, please suggest me some topics that I should consider for the project. Regards, MicroKernel :)

  • Processing an Integer Buried in a String in XSL

    - by justkt
    I have a stored time value which is of the format H:mm:ss. The hours may be any value from 0 up through several days. This data is sent in an XML tag and processed by XSL to be displayed. The display that I want is of the format: D days, HH:mm:ss (hours/minutes) Where the last tag shows hours if HH is greater than 0, minutes if it is 0. Given the original HH, which may be more than 24, I know I need the floor of HH / 24 to get the days value. Then the original HH % 24 gives me the leftover hours. I have also handled the minutes and hours question using xsl:when and xsl:if. It's getting days and hours from the hours value that has me stumped. EDIT So far, I'm looking at doing the following: Variable declaration <xsl:variable name="time"><xsl:value-of select="time" /><xsl:variable> <xsl:variable name="days"><xsl:value-of select="floor(substring-before(time, ':') / 24)" /></xsl:variable> <xsl:variable name="hours"><xsl:value-of select="substring-before(time, ':') mod 24" /></xsl:variable> <xsl:variable name="minutes"><xsl:value-of select="substring-after(time, ':')" /></xsl:variable> Use <xsl:if test="$days > 0"> <xsl:value-of select="$days" /> days </xsl:if> <xsl:value-of select="$hours" />:<xsl:value-of select="$minutes" /> <xsl:choose> <xsl:when test="$hours > 0"> hour<xsl:if test="$hours > 1">s</xsl:if> </xsl:when> <xsl:otherwise> minute<xsl:if test="$minute != '01:00'">s</xsl:if> </xsl:otherwise> </xsl:choose> And for clarification, a sample time would be <time>26:15:00</time> for 1 day 2:15 hours.

  • Background processing in rails

    - by hashpipe
    Hi, This might seem like a FAQ on stackoverflow, but my requirements are a little different. While I have previously used BackgroundRB and DJ for running background processes in ruby, my requirement this time is to run some heavy analytics and mathematical computations on a huge set of data, and I need to do this only about the first 15 days of the month. Going by this, I am tempted to use cron and run a ruby script to accomplish this goal. What I would like to know / understand is: 1 - Is using cron a good idea (cause I'm not a system admin, and so while I have basic idea of cron, I'm not overly confident of doing it perfectly) 2 - Can we somehow modify DJ to run only on the first 15 days of the month (with / without using cron), and then just stop and exit once all the jobs in the queue for the day are over (don't want it to ping the DB every time for a new job...whatever the jobs will be in the queue when DJ starts, that will be all). I'm not sure if I have put the question in the right manner, but any help in this direction will be much appreciated. Thanks

  • Dojo: dojo onblur events

    - by Jane Wilkie
    Hi guys, I have a form setup with dojo 1.5. I am using a dijit.form.ComboBox and a dijit.form.TextBox The Combobox has values like "car","bike","motorcycle" and the textbox is meant to be an adjective to the Combobox. So it doesn't matter what is in the Combobox but if the ComboBox does have a value then something MUST be filled in the TextBox. Optionally, if nothing is in the ComboBox, then nothing can be in the TextBox and that is just fine. In fact if something isn't in the Combobox then nothing MUST be in the text box. In regular coding I would just use an onBlur event on the text box to go to a function that checks to see if the ComboBox has a value. I see in dojo that this doesn't work... Code example is below... Vehicle: <input dojoType="dijit.form.ComboBox" store="xvarStore" value="" searchAttr="name" name="vehicle_1" id="vehicle_1" /> Descriptor: <input type="text" dojoType="dijit.form.TextBox" value="" class=lighttext style="width:350px;height:19px" id="filter_value_1" name="filter_value_1" /> My initial attempt was to add an onBlur within the Descriptor's <input> tag but discovered that that doesn't work. How does Dojo handle this? Is it via a dojo.connect parameter? Even though in the example above the combobox has an id of "vehicle_1" and the text box has an id of "filter_value_1", there can be numerous comboboxes and textboxes numbering sequentially upward. (vehicle_2, vehicle_3, etc) Any advice or links to resources would be greatly appreciated. Janie

  • Complex String Processing - well complex to me

    - by percent20
    I am calling a web service and all I get back is a giant blob of text. I am left to process it myself. Problem is not all lines are necessarily the same. They each have 2 or 3 sections to them and they are similar. Here are the most common examples text1 [text2] /text3/ text1/test3 text1[text2]/text3 text1 [text2] /text /3 here/ I am not exactly sure how to approach this problem. I am not too good at doing anything advanced as far as manipulating strings. I was thinking using a regular expression might work, but not too sure on that either. If I can get each of these 3 sections broken up it is easier from there to do the rest. its just there doesn't seem to be any uniformity to the main 3 sections that I know how to work with.

  • ASP.NET MVC 2: Mechanics behind an Order / Order Line in a edit form

    - by Dr. Zim
    In this question I am looking for links/code to handle an IList<OrderLine> in an MVC 2 edit form. Specifically I am interested in sending a complete order to the client, then posting the edited order back to an object (to persist) using: Html.EditorFor(m = m.orderlines[i]) (where orderlines is an enumerable object) Editing an Order that has multiple order lines (two tables, Order and OrderLine, one to many) is apparently difficult. Is there any links/examples/patterns out there to advise how to create this form that edits an entity and related entities in a single form (in C# MVC 2)? The IList is really throwing me for a loop. Should I have it there (while still having one form to edit one order)? How could you use the server side factory to create a blank OrderLine in the form while not posting the entire form back to the server? I am hoping we don't treat the individual order lines with individual save buttons, deletes, etc. (for example, they may open an order, delete all the lines, then click cancel, which shouldn't have altered the order itself in either the repository nor the database. Example classes: public class ViewModel { public Order order {get;set;} // Only one order } public class Order { public int ID {get;set;} // Order Identity public string name {get;set;} public IList<OrderLine> orderlines {get;set;} // Order has multiple lines } public class OrderLine { public int orderID {get;set;} // references Order ID above public int orderLineID {get;set;} // Order Line identity (need?) public Product refProduct {get;set;} // Product value object public int quantity {get;set;} // How many we want public double price {get;set;} // Current sale price }
