• Jquery load() help

  - by mtwallet

  Hi. I am creating a portfolio page for m personal site. I have a slider with approx 20 anchors that link to projects I have worked on, each one contains a client logo that when clicked should load some html content then fade that content into a container div on the same page. I have been advised to use the JQuery method load() which seems straight forward. The question I have is do I have to repeat the following code for each of the 20 anchors as the url is different for each one or is there a more efficient way? $('a#project1').click(function() { $('#work').load('ajax/project1.html'); } Also would I have to use the unload() method first to ensure the div I am loading into is empty? Many thanks in advance.

• How to best deal with photos passed to IFilter?

  - by sharptooth

  I'm implementing an IFilter for indexing image formats. One problem is photos - many users have tons of photos, photos are huge and loading and searching for text on them is time consuming. Yes, sometimes people use cameras instead of scanners for digitizing documents, but the potential problems IMO far outweight the possibility of encountering a document digitized with a photo camera. So my implementation will not extract text from photos at all. What should the IFilter do once it detects that a given file is a photo image - indicate an error or return empty text?

• php variable scope

  - by Illes Peter

  I have two files: index.php /lib/user.php Index contains the form: <div class="<? echo $msgclass; ?>"> <? echo $msg; ?> </div> <form id="signin" action="/lib/user.php" method="post"> ... </form> User.php makes all the processing. It sets $msg to 'some error message' and $msgalert to 'error' in case of any error. At the end of processing it uses header() to redirect to index.php But after redirection $msg and $msgalert get out of scope and index only gets empty vars. How can i fix this?

• custom validation does not seem to get registered.

  - by viet pham

  Hi, Inside a tab, I have a form that is dynamically loaded via ajax. Since the name of the field is dynamic too (e.g. ), I write a custom validation method inside the "on complete" like this. However, the custom code does not get executed (bolded alert never pops up) no matter what i try. $.ajax ( { url: 'index.php?func=trainingmgr&aAction=displayAddForm', type: 'GET', dataType: 'html', complete: function(req, err) { //Append response to the tab's body $(href, '#trainingTabs').append(req.responseText); $.validator.addMethod ( 'tRequired', function(value, element) { if(value == '') { **alert('I am empty');** return true; } else return false; }, '<br>Required field' ); $('#upload' + index).click ( function() { $('#addForm' + index).validate().numberOfInvalids(); } ); } } );

• IE6 Not submitting POST Data?!

  - by Abs

  Hello all, I have just tested my site on an old IE6 browser on a windows server. The problem I have is when I submit a form, the POST data I get on the other page is empty. Array(). This site has worked on IE6 on a different windows server, it has worked on my laptop and works on all other major browsers (Firefox, Chrome, IE6,7,8, Safari) etc. Its just this one machine. Is there a setting not to allow post data on IE6? Thanks all

• Loop over a file and write the next line if a condition is met

  - by 111078384259264152964

  Having a hard time fixing this or finding any good hints about it. I'm trying to loop over one file, modify each line slightly, and then loop over a different file. If the line in the second file starts with the line from the first then the following line in the second file should be written to a third file. !/usr/bin/env python with open('ids.txt', 'rU') as f: with open('seqres.txt', 'rU') as g: for id in f: id=id.lower()[0:4]+'_'+id[4] with open(id + '.fasta', 'w') as h: for line in g: if line.startswith(''+ id): h.write(g.next()) All the correct files appear, but they are empty. Yes, I am sure the if has true cases. :-) "seqres.txt" has lines with an ID number in a certain format, each followed by a line with data. The "ids.txt" has lines with the ID numbers of interest in a different format. I want each line of data with an interesting ID number in its own file. Thanks a million to anyone with a little advice!

• The Definition of Regular Languages

  - by AraK

  Good Day, I have tried, and burned my brain to understand the definition of Regular Languages in Discrete Mathematics and its Applications(Rosen) without reaching the goal of understanding why the definition is like that in this book. On page(789), I am rephrasing the definition: Type 3 grammars are defined as: w1 --> w2 Where w1 is a non-terminal, and w2 is of the form: w2 = aB w2 = a Where B is a non-terminal, and a is a terminal. A special case is when w1 is the starting symbol and w2 is lambda(the empty string): w1 = S S --> lambda Two questions I couldn't find an answer for. First, Why can't w2 be of the form Ba. Second, Why lambda is only allowed for the starting symbol only. The book states that, regular languages are equivalent to Finite State Automaton, and we can easily see that a we can build FSA for both cases. I took a look at other resources, and these restrictions don't exist in these resources. Thanks,

• Can you add identity to existing column in sql server 2008?

  - by bmutch

  In all my searching I see that you essentially have to copy the existing table to a new table to chance to identity column for pre-2008, does this apply to 2008 also? thanks. most concise solution I have found so far: CREATE TABLE Test ( id int identity(1,1), somecolumn varchar(10) ); INSERT INTO Test VALUES ('Hello'); INSERT INTO Test VALUES ('World'); -- copy the table. use same schema, but no identity CREATE TABLE Test2 ( id int NOT NULL, somecolumn varchar(10) ); ALTER TABLE Test SWITCH TO Test2; -- drop the original (now empty) table DROP TABLE Test; -- rename new table to old table's name EXEC sp_rename 'Test2','Test'; -- see same records SELECT * FROM Test;

• How do I identify an OpenID provider as requiring Directed Identity?

  - by Skrat

  I am trying to extend the LightOpenID PHP library to "discover" that an identity provider requires Directed Identity. This should be easy as the library is beautifully well written and wonderfully clean but I don't know how to identify these types of providers. A couple things I've tried: I looked through the OpenID specs on the subject but came up empty handed. Looked through the PHP OpenID library but couldn't figure out how this info was gathered during the discovery. Dumped all the data (headers and content) that came from the servers by injecting some code in LightOpenID but didn't see anything helpful. Searched Google and Stackoverflow, naturally. How do providers identify themselves as requiring "Directed Identity" authentication? Surely there is a carefully defined specification for this... somewhere. Anyone know where I can find more on this?

• Best way of implementing DropDownList in ASP.NET MVC 2?

  - by Kelsey

  I am trying to understand the best way of implementing a DropDownList in ASP.NET MVC 2 using the DropDownListFor helper. This is a multi-part question. First, what is the best way to pass the list data to the view? Pass the list in your model with a SelectList property that contains the data Pass the list in via ViewData How do I get a blank value in the DropDownList? Should I build it into the SelectList when I am creating it or is there some other means to tell the helper to auto create an empty value? Lastly, if for some reason there is a server side error and I need to redisplay the screen with the DropDownList, do I need to fetch the list values again to pass into the view model? This data is not maintained between posts (at least not when I pass it via my view model) so I was going to just fetch it again (it's cached). Am I going about this correctly?

• How to add a margin to a CheckedListBox in .NET?

  - by Xanatos

  I'm writing an windforms application using .NET (actually IronPython, but that's not relevant), and I have a CheckedListBox object in my GUI. It's working fine, it has about 20 items in a multicolumn layout. But I can't figure out how to give the thing a nice internal margin--I want to insert around 20 or 30 pixels of whitespace around the top, bottom, left, and right edges of the checkboxes. To be clear, I want the whitespace to appear between the border of the CheckedListBox and the Checkboxes inside it, not outside the whole component. Hopefully this is an easy answer, and I'm just missing it cause I'm new to programming in windows. If its not possible, I guess that'd be good to know too, so I don't waste anymore time with it. (If I were doing this in Swing (Java) I would be looking to set the Insets on my component, or maybe build up a compound border with some empty space in it.)

• URL encoded POST bad practice?

  - by StackedCrooked

  I am (just for fun) trying to implement a High Score web-service. I would like it be compatible with REST principles. I want to be able to add a new highscore using url parameters like this http://mydomain.com/hs/add&name=John&score=987. According to REST this must be done using a POST request. Which leads to empty POST request with all data contained in the URL parameters. Would this be considered a bad practice? Update Security is currently not a big concern.

• jQuery UI datepicker options as varialbe

  - by Desmond Liang

  I have a number of inputs on a page function as JQ UI datepicker. Each needs to have different settings. I want to minimize the JS so I save the settings as an attribute in each individual . <input type="text" class="datepicker" name="dateofbirth" id="dateofbirth" size="20" value="" options="{ dateFormat: 'yy-mm-dd',changeYear: true,yearRange: '1920:2010'}" /> <input type="text" class="datepicker" name="expdate" id="expdate" size="20" value="" options="{ yearRange: '2011:2020'}" /> I use js to load the options dynamically as the settings. $(document).ready(function(){ $(".datepicker").each(function(index){ $(this).datepicker("option" , $(this).attr('options')); }); }); datepicker is not functioning. If I empty the parentheses after $this.datepicker it works fine. I have also tried another way to assign settings. ("option",...) no dice.

• Best way to implement refusing a value change by the user in Swing?

  - by Michael Borgwardt

  I have a JCheckBox that should not be checked by the user when a certain other field is empty. So now I want to have an error popup and then reset the checkbox (I've considered disabling the checkbox, but the connection to the other field is non-obvious, and a tooltip text IMO not visible enough). What's the correct way to do that in Swing? Through a PropertyVetoException? Where do I throw it and where do I catch it? My first (probably ugly) idea would be to add a ChangeListener that itself shows the popup and resets the value.

• Disappearing Inlineshapes

  - by Rick

  I frequently edit files that have numerous inlineshapes, one per paragraph. One of the edits I make is to eliminate "double" paragraph marks either using Search and Replace or a simple macro that performs the same operation (e.g., search for "^p^p" and replace with "^p"). This operation works fine in Word 97-2003 documents (.doc), but when I try it on .docx documents, I lose all of the inlineshapes. The .docx files seem to ignore the inlineshape, therefore seeing the paragraphs containing them as "empty". Search and Replace sees "^p^p", replaces it with "^p", and the graphic goes away. Any thoughts on how to work around this?

• Forcing WCF proxy to generate an alias prefix

  - by Sean Campbell

  To comply with a clients schema, I've been attempting to generate a WCF client proxy capable of serializing down to a structure with a root node that looks like the following: <quote:request xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:quote="https://foo.com/services/schema/1.2/car_quote"> After some reading, I've had luck in updating the proxy to include the required 'quote' namespace through the use of XmlNameSpaceDeclarations and XmlSerializerNamespaces [System.SerializableAttribute()] [System.ComponentModel.DesignerCategoryAttribute("code")] public partial class request { [XmlNamespaceDeclarations()] public XmlSerializerNamespaces xmlsn { get { XmlSerializerNamespaces xsn = new XmlSerializerNamespaces(); xsn.Add("quote", "https://foo.com/services/schema/1.2/car_quote"); return xsn; } set { //Just provide an empty setter. } } ... which delivers: <request xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:quote="https://foo.com/services/schema/1.2/car_quote"> however I'm stumped as to how to generate the quote:request element. Environment: ASP.NET 3.5 Thanks

• Are there any good videos out there on Java Design Patterns?

  - by Becky Reamy

  My team would like to spend some time at lunch learning design patterns. Previously, we watched some videos on Javascript which we found very useful as a way to start discussions. We would like to do the same thing with design patterns so that we don't have to spend a lot of time (outside of work) researching individual patterns in order to give a presentation. I did a little searching and came up fairly empty handed. Any help would be appreciated. It doesn't even have to be a video, even something that we can listen to (maybe a book on tape even).

• Pear MDB2 class and raiserror exceptions in SQL Server

  - by drholzmichl

  Hi, in SQL Server it's possible to raise an error with raiserror(). I want to use a severity, which doesn't interrupt the connection. This error is raised in a stored procedure. In SQL Management Studio all is fine and I get my error code when executing this SP. But when trying to execute this SP via MDB2 in PHP5 this doesn't work. All I get is an empty array. MDB2 object is created via (including needed options): $db =& MDB2::connect($dsn); $db->setFetchMode(MDB2_FETCHMODE_ASSOC); $db->setOption('portability',MDB2_PORTABILITY_ALL ^ MDB2_PORTABILITY_EMPTY_TO_NULL); The following works (I get a PEAR error): $db->query("RAISERROR('test',11,0);"); But when calling a stored procedure which raises this error via $db->query("EXEC sp_raise_error"); there is not output. What's wrong?

  Hi. I am trying to use JSON.stringify() (from json2.js of json[dot]org ) to convert a JavaScript array to JSON string and to pass it to an asmx web method. I use jQuery AJAX. The call reaches the web method where I take a List <Object> as parameter but I get an empty list there in debug mode. My JSON string looks like well formed with all data , I even tried having single-quotes and double-quotes(escaped) around the 'names' of the JSON string. Please help.

• Assembly.CodeBase: when is it no file-URI?

  - by Marc Wittke

  Assembly.Location gives a plain path to the assembly. Unfortunately this is empty when running in a shadowed environment, such as unit test or ASP.NET. Hovever, the Codebase property is available and provides a URI that can be used instead. In which cases it returns no URI starting with file:///? Or in other words: what are the cases in which this won't work or will return unusable results? Assembly assembly = GetType().Assembly; Uri codeBaseUri = new Uri(assembly.CodeBase); string path = codeBaseUri.LocalPath;

• Show them the default, and allow them to press escape or Ctrl-Z

  - by cf_PhillipSenn

  I have a table cell, and when the user clicks on it, I replace the contents of the table cell with an input tag with the current contents as the default. But I don't like it's behavior because there's a chance that the user can delete the contexts on the input simply by clicking on it a second time. $('.LastName').live('click', function() { var myText = $(this).text(); $(this).empty().append('<input name="LastName" id="LastName" value="' + myText + '" />'); document.myForm.LastName.focus(); }); Q: How do I give the user a default, plus allow them to press the escape key or Ctrl-Z while in the middle of an edit?

• How do I find out if the variable is declared in Python?

  - by golergka

  I want to use a module as a singleton referenced in other modules. It looks something like this (that's not actually a code I'm working on, but I simplified it to throw away all unrelated stuff): main.py import singleton import printer def main(): singleton.Init(1,2) printer.Print() if __name__ == '__main__': pass singleton.py variable1 = '' variable2 = '' def Init(var1, var2) variable1 = var1 variable2 = var2 printer.py import singleton def Print() print singleton.variable1 print singleton.variable2 I expect to get output 1/2, but instead get empty space. I understand that after I imported singleton to the print.py module the variables got initialized again. So I think that I must check if they were intialized before in singleton.py: if not (variable1): variable1 = '' if not (variable2) variable2 = '' But I don't know how to do that. Or there is a better way to use singleton modules in python that I'm not aware of :)

• Safe HttpContext.Current.Cache Usage

  - by Burak SARICA

  Hello there, I use Cache in a web service method like this : var pblDataList = (List<blabla>)HttpContext.Current.Cache.Get("pblDataList"); if (pblDataList == null) { var PBLData = dc.ExecuteQuery<blabla>( @"SELECT blabla"); pblDataList = PBLData.ToList(); HttpContext.Current.Cache.Add("pblDataList", pblDataList, null, DateTime.Now.Add(new TimeSpan(0, 0, 15)), Cache.NoSlidingExpiration, CacheItemPriority.Normal, null); } I wonder is it thread safe? I mean the method is called by multiple requesters And more then one requester may hit the second line at the same time while the cache is empty. So all of these requesters will retrieve the data and add to cache. The query takes 5-8 seconds. May a surrounding lock statement around this code prevent that action? (I know multiple queries will not cause error but i want to be sure running just one query.)

• PHP: Filling in the 'gaps' in an array

  - by aboved

  Hey gurus, I've got a php array (obtained through checkbox values in a form - as you know checkboxes only show up in the _POST variable when they are not set). Array ( [2] => 0,2 [3] => 0,3 ) I need a way to 'fill in' the gaps between the range 0-5. So above would look like (filling the empty spaces with '-1'. I tried array_merge() with an array filled with '-1' but that didn't work. Array ( [0] => -1 [2] => 0,2 [3] => 0,3 [4] => -1 [5] => -1 ) I think I may have gone down the wrong road with the problem I am trying to solve, but I have put too much time into this solution to back out - a feeling I am sure most of you are familiar with(!) Cheers!
