• Colouring JTree's TreeNodes

  - by Amadan

  I have a JTree which I give objects that implement the TreeNode interface, and a custom TreeModel to display them (not using DefaultMutableTreeNode). I would like to change the text colour of some nodes. I can't find anything in the docs, except javax.swing.tree.DefaultTreeCellRenderer.setTextNonSelectionColor(Color newColor), but it will change everything indiscriminately, and I only need it for some nodes (specifically, broken links, i.e. nodes whose corresponding files can't be found on the disk, should be greyed out, the rest should be default). Can it be done, and how?

• Can mod_rewrite do math?

  - by ewall

  I am planning to convert my website to a new CMS, but I would like to use mod_rewrite to seamlessly redirect old links to their new locations. The catch is that my new blog will not have the same article numbers as the old, because I'll import some older blog entries in their first. Thus, my mod_rewrite would need to take a URL like old.php?article=125, do the addition to figure out the new article number (say +200, for this example), and redirect to new.php?i=325. Can mod_rewrite do the addition on its own, or am I going to need some kind of 'helper' script to do that?

• Converting DAO to ADO

  - by webworm

  I am working with an Access 2003 database that has a subroutine using DAO code. This code loops through the table definitions and refreshes the ODBC connection string. I would like to convert this to ADO so I do not have to reference the DAO object library. Here is the code ... Public Sub RefreshODBCLinks(newConnectionString As String) Dim db As DAO.Database Dim tb As DAO.TableDef Set db = CurrentDb For Each tb In db.TableDefs If Left(tb.Connect, 4) = "ODBC" Then tb.Connect = newConnectionString tb.RefreshLink Debug.Print "Refreshed ODBC table " & tb.Name End If Next tb Set db = Nothing MsgBox "New connection string is " & newConnectionString, vbOKOnly, "ODBC Links refreshed" End Sub The part I am unsure of is how to loop through the tables and get/set their connection strings.

• How can I replace jQuery Tools Scrollable bullets with numbers?

  - by Steven

  I'm using jQuery Tools for creating an article carousel. You can see in action with images here: http://flowplayer.org/tools/demos/scrollable/plugins/index.html The navigation code looks like this: <!-- wrapper for navigator elements --> <div class="navi"></div> And the plugin ads links like so: <!-- wrapper --> <div class="navi"> <a href="0" class="active"/> <a href="1" class=""/> <a href="2" class=""/> </div> The code to get it all started goes like this: $(".scrollable").scrollable({ circular: true, size: 1}).navigator(); My question is: How can I replace <a href="1" class=""/> with <a href="1" class=""> [1] </a> ?

• Can you use PHP libcurl to pull files from server A to server B?

  - by Majid

  Hi, cURL and libcurl let you do things you normally do with a browser, right? Like, as if you have a jini sit inside a server and fire up a browser and do stuff. Ok then. I need a script to sit on server B, and click on download links on a server A and download files (from server A to server B). I am new to curl, and not sure if all I need is to issue a simple get or something else. I know that Content-disposition header forces the browser to save the document. Does it have the same effect on libcurl too? If it does, I'll make my serving script on server A send that header, and then serve the file. Any advice is appreciated. Thanks

• Approaches to wrapping access to functionality in .NET MVC?

  - by Kevin

  What are some different solutions to wrapping access to functionality within a .NET MVC application? For example, I have six tabs that represent different areas of the application and within area 1, there is the ability to add, edit, upload, whatever. I need a central way to say: Build some dictionary of what the user can do Wrap tabs, buttons, links, etc, validate the user can access this piece of functionality and show/hide appropriately. I know I can restrict access to actions via action filters and roles, but what about from the UI? Any help would be appreciated. I am sure I am not the only one who has needed to do this, thanks!

• RESTful services and update operations

  - by Igor Brejc

  I know REST is meant to be resource-oriented, which roughly translates to CRUD operations on these resources using standard HTTP methods. But what I just wanted to update a part of a resource? For example, let's say I have Payment resource and I wanted to mark its status as "paid". I don't want to POST the whole Payment object through HTTP (sometimes I don't even have all the data). What would be the RESTful way of doing this? I've seen that Twitter uses the following approach for updating Twitter statuses: http://api.twitter.com/1/statuses/update.xml?status=playing with cURL and the Twitter API Is this approach in "the spirit" of REST? UPDATE: PUT - POST Some links I found in the meantime: PUT or POST: The REST of the Story PUT is not UPDATE PATCH Method for HTTP

• Editing and iPhone SDK Framework ?

  - by Chris

  I am working with MapKit and want to be able to add a (NSString *)itemTag value to each of my annotations. I have created myAnnotiation.m and myAnnotation.h I tried adding itemTag to the myAnnotation.h/m but when I try to access currentAnnotation.itemTag within my main code, it says "itemID not found in protocols" - so I went to the MapKit.Framework and into MKAnnotation.h. I added (NSString *)itemID, but when I save the .h file in the Framework, it changes the file's icon and doesn't appear to by jiving with everything else. Any help or links to help would be greatly appreciated. I am not even sure if I'm on the right path here, but Googling "modify iphone sdk framework" does not turn up much.

• how to perform click to the output of ActionLink by jQuery or javascript?

  - by user324003

  <%= Ajax.ActionLink("Edit", "Update", "Home", new { id = item.mID }, new AjaxOptions { OnBegin = "function(){ $('#edit" + item.mID + "').show();}", HttpMethod = "get", UpdateTargetId = "edit" + item.mID })%> The above code generates the html source code. when user click the link, it works well. But there're so many links there, I must click them one by one. Is there any method to click once, all of them excutes? I tried the method: $("a.buttonID").click() and modified the above code: <%= Ajax.ActionLink("Edit", "Update", "Home", new { id = item.mID }, new AjaxOptions { OnBegin = "function(){ $('#edit" + item.mID + "').show();}", HttpMethod = "get", UpdateTargetId = "edit" + item.mID } new{@class="buttonID"})%> But it doesn't work. Because it only excutes the onclick event of a tag, the href attribute doesn't work.

• Get highest frequency terms from Lucene index

  - by Julia

  Hello! i need to extract terms with highest frequencies from several lucene indexes, to use them for some semantic analysis. So, I want to get maybe top 30 most occuring terms(still did not decide on threshold, i will analyze results) and their per-index counts. I am aware that I might lose some precision because of potentionally dropped duplicates, but for now, lets say i am ok with that. So for the proposed solutions, (needless to say maybe) speed is not important, since I would do static analysis, I would put accent on simplicity of implementation because im not so skilled with Lucene (not the programming guru too :/ ) and cant wrap my mind around many concepts of it.. I can not find any code samples from something similar, so all concrete advices (code, pseudocode, links to code samples...) I will apretiate very much!!! Thank you!

• AJAX Beginner: If then statement

  - by dassouki

  In menu.html, I have my menu items(a href links), let's call them, menu_1, menu_2, .... In map.js displays the contents of a map, it calls an API to display some layers and maps. I have a lot of maps to show but i only want to call the api once. Using AJAX, I was wondering if it's possible to have an if/then or select/case in my js, so that if menu_1 is clicked, then implement map_1 etc. without having the page to reload. The only way I thought I could do this is using Post/get .. so when you click on menu_1 it takes you to page.php?page_id=1 . JS will read that and display the map. I'm new to JS and AJAX so please feel free to butcher me

• wordpress permalinks

  - by codedude

  I set my wordpress permalink structure to /%postname%/ but now when I go to a page other than the home page (for example if I went to somelink.com/about) I lose all javascript references. I think this happens because the links to the js files are no longer right as it is in the imaginary folder "about". This is how the js files are referenced in the header.php file. <script type="text/javascript" src="wp-content/themes/default/js/jquery-1.4.2.min.js"></script> <script type="text/javascript" src="wp-content/themes/default/js/cufon-yui.js"></script> <script type="text/javascript" src="wp-content/themes/default/js/Goudy_Bookletter_1911_400.font.js"></script> <script type="text/javascript"> $(document).ready(function() { Cufon.replace('h1'); Cufon.replace('h3', {textShadow:'0 1px #fff'}); }); </script> Am I doing something wrong?

• How do I host a Google gadget? How does it work?

  - by sintaloo

  I just spent 5 hours by checking Google gadgets websites and FAQs, but I still have no idea how to host a gadget. What I've figured from reading the Google documentation: I can write gadgets with XML, JavaScript etc.. Gadgets can be added to iGoogle etc.. Google can host the gadgets for you. Gadgets can be hosted anywhere else??? All of the above information doesn't answer my question. For instance, with jQuery or Dojo Toolkit, I can download the JavaScript framework and use it. With Google gadgets, I can not find a download link for a framework. Why? Does Google provide its framework? If not, why does the documentation indicate that gadgets can be hosted anywhere? I am totally confused. A brief explanation or some helpful links are very welcome! Thanks a lot!!!

• I want to combine my www and non www and keep the link jucie from both.

  - by John Ray

  My website shows up for some keywords in the www and some in the non www. Seaquake shows more links to the non www version. It is a PR2 either way. I would like to combine the link juice of the two versions into the non www version. Does anyone know the best way to combine the two and keep the link juice of both. It is as simple as a 301 redirect and if so does the 301 need to be handled in any specific way.

• How do I set up derby in eclipse on Ubuntu?

  - by Everett

  The question basically says it all. I'm trying setup up JavaDB on my virtualbox running Ubuntu 9.10. I have the package downloaded and installed through the package manager, which I believe is the right to go about it. I have also installed the Eclipse's Data Platform Tools. I've been following this tutorial here: http://www.vogella.de/articles/EclipseDataToolsPlatform/article.html. I'm stuck at the driver definition step. When I select the driver template from the Name/Type tab and the jar file in the Jar List tab, the OK button is never enabled. At the top of the New Driver Definition dialog it says 'Unable to locate Jar/zip in the file system as specified by the driver definition: derby.jar.' I assume this is the problem. Any help or links to a better tutorial would be much appreciated.

• Can an Aspect conditionally render parts of a JSP page ?

  - by Scott The Scot

  At present the jsp pages have normal authorize tags to conditionally render links and information etc. The website is on the intranet, and we're using Spring Security 2.0.4. Ive now got a business user who wants to allow all roles to access everything for the first few weeks, then gradually add the security back in as feedback is gathered from the business. Rather than go through every page, removing the authorize tags, only to have to put them back in, is is possible to configure these through an aspect, or is there any other way to externalize this into a config file ? I've found Spring's MethodSecurityInterceptor and the meta data tags, but these wouldn't give me the externalization. I've been on google for the last hour, and am now pretty sure this can't be done, but would love to find out I haven't been asking the right questions. Advice appreciated

• Functional Specifications vs. Requirements Document

  - by KP

  Guys, Currently in my comp., there are some changes going on regarding project documentation. There is a LOT of time and effort spent on discussing functional specs vs. requirements doc. However, I don't think anyone here understands the reason why you would use one over the other. Therefore, I don't understand the difference myself. Can someone shed some light on this matter plz? If you have links to articles, blog posts, etc. that would be helpful too. Thanks

• Advantages of three-way automatic merging vs. two-way

  - by bnsmith

  I'm interested in understanding two-way and three-way merging of source code files. Based on what I've read, two-way merging has some "crippling weaknesses" compared to three-way merging. What I'd really like to see are one or two simple, concrete examples of cases where three-way merging is able to automatically merge something from a branch to the trunk without producing conflicts, while two-way merging falls down and requires a bunch of manual intervention to get the code merged. Any links to blog posts or even references to books would be appreciated (yes, I have Googled this for an hour or so). Thanks!

• Wordpress TinyMCE keeps it clean, how?

  - by Frankie

  I've noticed that the latest version of TinyMCE on Wordpress manages text in a very 'clean' way. Pasting from MS-Word it strips out all html text blocks, like <p>'s, and shows the text cleared of any odd formatting preserving only links, bolds and underlines. On top of that the source code format is very clear. No <br />'s everywhere. You only see \n's and the expected <strong><u><i> tags. I've been messing up with TinyMCE configuration files for some time with little success. I did manage to get all formatting removed. I can't, however, put TinyMCE to display the \n's as <br />'s lie Wordpress does it. Tried preformatted : true with no success whatsoever. Has anyone here been able to do it? Thank you in advance, Francisco

• Removing a result from Queryset

  - by Enrico

  Is there a simple way to discard/remove the last result in a queryset without affecting the db? I am trying to paginate results in Django, but don't know the total number of objects for a given query. I was planning on using next/previous or older/newer links, so I only need to know if this is the first and/or last page. First is easy to check. To check for the last page I can compare the number of results with the pagesize or make a second query. The first method fails to detect the last page when the number of results in the last set equals the pagesize (ie 100 records get broken into 10 pages with the last page containing exactly 10 results) and I would like to avoid making a second query. My current thought is that I should fetch pagesize + 1 results from the db. If the queryset length equals 11, I know this is not the last page and I want to discard the last result in the queryset before passing the queryset to the template.

• Add remove class?

  - by Steven

  Okay I have two classes for two links and two divs with different information. What I am trying to do is have it so when you click on one link it adds a 2 to both of the classes and makes the second div visable. When you click on the other link it takes off a 2 and makes the first div visable. Here is what I currently got $("#posts").click(function () { $("#sideboxtopleft").toggleClass("2"); $("#arrow").toggleClass("2"); }); Pretty much posts is the link, when when you click on it. It would make sideboxtopleft and arrow, sideboxtopleft2 and arrow2 and when you clicked on comments it would take off the 2 of both of those. Then there are two divs, one is set to hidden and I want to make it visable and set the other to hidden. Pretty much creating a tab system with changing tab classes.
