• Can't store Data URI to database without stripping + characters

  - by citizencane

  I am trying to grab a reference to images with src's in URI scheme. An example would be the images on google.com/news. if I alert(escape(saveObj.image)); I get something like below: data%3Aimage/jpeg%3Bbase64%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 I pass that from the js file and am using django to get that into a mysql table of type utf8_unicode_ci using modelform.save, but when i examine what's in the database, I see: data:image/jpeg;base64,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 nXF/pZFKuffViGPW5ximQUEz1cNdPNKms6g8TlWBufDcHyxsdLUmqoYqhiWZ1BYtsSe The key difference is that in my database all of the '+' characters from the original have been stripped and replaced with spaces.

• Passing along variable inside link works only on first word in multiple-word-variables, why?

  - by Camran

  I have this code below. As you can see I am passing two variables along with the link. The second variabye (category) works whenever it consists of one word, but some categories are two words or more, and then on the receiving php page where I fetch the variable only the first word is fetched. Any ideas? Example: I pass along this: Rims & Tires Only this comes through: Rims $display_table .= "<a href='../ad.php?ad_id=$row[ad_id]&category=$row[category]' target='_parent'>"; Here is how I fetch it in the receiving php file (which the link is to): $cat = $_GET['category']; echo $cat; //displays only first word of multiple word categories. Thanks

  - by Nubkadiya

  i want to use google map api for my desktop application. the application will be totally connected to internet. while i was searching some research notes about this implementation. i found a ideal site with the configurations. but it has some java files to be downloaded. but when i tried that website its not loading. which is swinglabs.org http://today.java.net/pub/a/today/2007/10/30/building-maps-into-swing-app-with-jxmapviewer.html any other options of doing this api implementation to my desktop application. and one more thing. i tried downloading the google api. even it ask a url. we have to provide a url then only we get a key to download it. and the api should run in that specific url. otherwise its not working. how this appears to a desktop application any ideas welcome..

• Remote Seam Persistence

  Hi. I have a button in a .xhtml file which calls a javascript function which calls a java function remotely (in jboss seam environment). That java function has an entityManager.persist(object). Do you know why this line of code doesn't commit to the DB? It says something that a transaction hasn't started. I supose in a remote context i don't have a transaction began because if i put an action on that button which calls the same java function instead of using javascript is above, it works fine; entityManager persists the object and i can see it in the DB. Does anyone has any ideas how could i make to actually persist the object using javascript to call the java function? (i have to use javascript because i need the callback function )

• Eclipse Plugin: Enablement of an Action based on the current selection - before the

  - by Itay

  Here's my problem: I am using the org.eclipse.ui.popupMenus extension point for adding a sub-menu whose Action that is bounded to the following class: public class MyAction implements IObjectActionDelegate { private Logic logic = Logic.getInstance(); // Singleton public void setActivePart(IAction a, IWorkbenchPart targetPart) { // Nothing here } public void run(IAction a) { // Do something... } public void selectionChanged(IAction a, ISelection s) { a.setEnabled(logic.isEnabled(s)); } } This action is working correctly in most cases (including the call a.setEnabled() in selectionChanged()). My problem at the very first time my action is being invoked. The selectionChanged method is called only after the menu item has been displayed (and not when the user has made the selection) which means that the call to a.setEnabled() will have no affect. Any ideas on how to make my action receive selectionChanged() notifications even before the fist time it is being invoked?

• Rails: Is there a way to check for incomplete JPG file upload?

  - by user206481

  I have a Rails app that processes and serves up jpg files that were uploaded via FTP. On several occasions the FTP process was disconnected and left many incomplete .jpg files. I was surprised to see that the incomplete jpgs behave as normal jpg files in my app even tho they have incomplete image data. I have since implemented a more robust FTP process where the uploaded file is initially *.tmp and gets renamed to .jpg after an FTP success code is received. My problem is, I still have all of these incomplete jpg files on the server and can't figure out how to programmatically weed them out. I can actually display them in a view without generating any errors, but there is only a partial image there. I tried RMagick but they all successfully load (using Image.read) and report the valid x & y resolutions. I have so far not been able to determine a way to programmatically differentiate between an incomplete and complete jpg uploaded image. Any ideas?

• Div behind another div problem.

  - by Kyle Sevenoaks

  Here is a (big) example of the massive problem I am having, when this page is live at euroworker.no/order, it is dynamically generated, I have supplied a static version for people to mess with. All I need is where it says "Endre Valg" to push the div wrapper under it down.. Sounds easy huh? I have tried many many things, I hope that some discussion and even trial and error can help us here. Sorry for the huge amount of code and stuff but this has taken me all day and I am out of ideas. Thanks.

• Fast way to pass a simple java object from one thread to another

  - by Adal

  I have a callback which receives an object. I make a copy of this object, and I must pass it on to another thread for further processing. It's very important for the callback to return as fast as possible. Ideally, the callback will write the copy to some sort of lock-free container. I only have the callback called from a single thread and one processing thread. I only need to pass a bunch of doubles to the other thread, and I know the maximum number of doubles (around 40). Any ideas? I'm not very familiar with Java, so I don't know the usual ways to pass stuff between threads.

• JS DOM: Get elements by text content.

  - by hristo

  Hello! I am looking for a way to perform fulltext search on the DOM tree with JS. In two words, I would like to retrieve the list of text nodes which contain a given string. I've tried mootools' Element.getElements ( ':contains[string]' ) but I can't get it to work with strings containing whitespace. I'm thinking about simply indexing all text nodes and checking against each node for the string being searched for, but, in my project, there's no way of telling when the DOM updates in order to maintain such an index up-to-date. Any better ideas? Thanks

  Hello, I have a table in my php code. In the second column of the table, normally it displays "---", and after i click the submit button, it will display the calculating result in the same page. For example, <table> <tr><td>1</td><td>---</td></tr> <tr><td>2</td><td>---</td></tr> <tr><td>3</td><td>---</td></tr> </table> And in the same page, it should receive the variables $var1 = $_POST['variable1']; I'm not sure which way to use, ajax or javascript or just css?

• Problematic behavior of Linq Union?!

  - by Foxfire

  Hi, consider the following example: public IEnumerable<String> Test () { IEnumerable<String> lexicalStrings = new List<String> { "test", "t" }; IEnumerable<String> allLexicals = new List<String> { "test", "Test", "T", "t" }; IEnumerable<String> lexicals = new List<String> (); foreach (String s in lexicalStrings) lexicals = lexicals.Union (allLexicals.Where (lexical => lexical == s)); return lexicals; } I'd hoped for it to produce "test", "t" as output, but it does not (The output is only "t"). I'm not sure, but may have to do something with the deferred processing. Any ideas how to get this to work or for a good alternative?

• Excel VBA: can delete validation but not add new one

  - by user1882965

  My code is as follows If Cells(Target.Row, 2) = "" And (Cells(Target.Row, 3) = "" Or Cells(Target.Row, 3) = "") Then Sheets("MySheet").Activate Cells(Target.Row, 3).Activate ActiveCell.Validation.Delete If (Cells(Target.Row, 2) = "Type A") Then ActiveCell.Validation.Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, Operator:=xlBetween, Formula1:="=AvailableVersions" ElseIf (Cells(Target.Row, 2) = "Type B") Then ActiveCell.Validation.Delete Else ActiveCell.Validation.Add Type:=xlValidateWholeNumber, AlertStyle:=xlValidAlertInformation, Formula1:="0", Formula2:="9999999" End If End If So the issue I am having comes whenever I reach ActiveCell.Validation.Add Run Time Error '1004': Application-defined or object-defined error Not a very helpful error, and also this occurs with both number and list validation type, so I am sure it is not an issue with the list itself which has workbook level scope anyway. It never occurs on ActiveCell.Validation.Delete which I find weird? I have been all over google trying to find a solution, and most suggest that it is caused by running dynamic validation code from a button which hogs focus despite the Activate call, but I am running on sheet change event rather than on button press so I don't think this is my issue - any ideas? I've wasted basically a whole day on this! :(

• How can a string timestamp with hours 0 to 24 be parsed

  - by user897052

  I am trying to parse a string timestamp of format "yyyyMMddHHmmss" with DateTime.ParseExact(). The catch is I must allow for an hour value of "24" (i.e. hours can be from 0 to 24; Note: I can't control the input values.) and, of course, that results in an exception. Are there any settings/properties I can set instead of manually parsing/using regex's? If not, any efficient parsing ideas? ex. DateTime.ParseExact("20120911240000", "yyyyMMddHHmmss", System.Globalization.CultureInfo.InvariantCulture); hour 24 means hour 0 of next day (so day + 1, hour = 0)

• Creating TCP network errors for unit testing

  - by Robert S. Barnes

  I'd like to create various network errors during testing. I'm using the Berkely sockets API directly in C++ on Linux. I'm running a mock server in another thread from within Boost.Test which listens on localhost. For instance, I'd like to create a timeout during connect. So far I've tried not calling accept in my mock server and setting the backlog to 1, then making multiple connections, but all seem to successfully connect. I would think that if there wasn't room in the backlog queue I would at least get a connection refused error if not a timeout. I'd like to do this all programatically if possible, but I'd consider using something external like IPchains to intentionally drop certain packets to certain ports during testing, but I'd need to automate creating and removing rules so I could do it from within my Boost.Test unit tests. I suppose I could mock the various system calls involved, but I'd rather go through a real TCP stack if possible. Ideas?

• Maintaining stored procedures in source control

  - by dub

  How do you guys maintain your stored procedures? I'd like to keep versions of them for a few different reasons. I also will be setting up cruisecontrol.net and nant this weekend to automate builds. I was thinking about coding something that would generate the create scripts for all tables/sprocs/udf/xml schemas in my development database. Then it would take those scripts and update them in source control every couple hours.... Ideally, I'd like to make this some sort of plugin/module for cruisecontrol.net. Any other ideas?

• WordPress > microsites use main site's menu (same domain, multiple subdirectories, multiple WP insta

  - by Scott B

  I have a main site at site.com and several subdirectory "microsites" at site1.site.com, site2.site.com, etc. These are all on the same server. Each site is set up in its own folder under public_html and each with its own separate wordpress install. I'd like for each microsite to share the same top level menu (the page's menu) with the main site. I'm sure there are several approaches and I'd like to ask you for a few ideas. As an aside, I'd also like to ask if the new WordPress 3.0 beta would make this simpler to do (since it combines wordpress MU into the main wordpress core)

• How do I get the current Application Name (in terms of IIS) in a classic asp Web application

  - by Mr AH

  I have a classic asp application which retrieves the current application name and sets an Application variable containing that name. This name is important (I wont go into why) and is essentially the friendly name in IIS. The problem is, the implementation used to get this name is flawed, it a) assumes the home directory contains the string wwwroot, and b) assumes the folder name is the same as the application name. I can no longer guarantee these conditions. I would have thought the application name is know at run-time but I can't seem to find it in either Session or Application variables (at application start up entry point in global.asa). Any ideas?

• retrieve Scrollbar position with javascript

  - by Paul

  I know how to do this in flash, but completely lost about regular html. I'm trying to detect the position of the browser scrollbar with Javascript to decide where abouts in the page the current view is. My guess is that I'd have to detect where the thumb on the track is, and then the height of the thumb as a percentage of the total height of the track. Am I over-complicating it, or does Javascript offer an easier solution than that? Any ideas code-wise. Thanks.

• Can layouts be chosen by Grails controllers?

  - by maerics

  I'm building a CMS as a learning exercise in Grails and would like to give content managers the ability to choose between different HTML page structures (e.g. 2 column, 3 column, etc). Grails Layouts seem like a logical choice but is it possible for a Grails controller to explicitly name which layout will be used for rendering? Ideally there would be a layout option to the render method, per Ruby on Rails but I don't see anything like it. It seems like it might be possible using the applyLayout method by passing the name of the layout but this requires each GSP page to explicitly request layout (annoying overhead per-page) rather than using Layout by Convention. Any ideas?

• Updating .class file in a jar throws exception

I'm trying to update the .class file in the jar using jar uf jar-file .class-file, however when I do this I get the following: java.util.zip.ZipException: duplicate entry: META-INF/LICENSE.txt at java.util.zip.ZipOutputStream.putNextEntry(ZipOutputStream.java:175) at java.util.jar.JarOutputStream.putNextEntry(JarOutputStream.java:90) at sun.tools.jar.Main.update(Main.java:507) at sun.tools.jar.Main.run(Main.java:184) It turns out there are 2 LICENSE.txt files in the jar and I can't seem to get rid of them. Any ideas on how to just get the new .class file into the jar or how to get rid of the duplicate file?

• View changes nvarchars to varchars in SQL Server 2008

  - by Traples

  I have a view in a SQL Server 2008 db that simply exposes about 20 fields of one table to be consumed via ODBC to a client. When I tried to replicate this view in another database, the client could not consume the data source. Then I noticed some weirdness. The columns in the view are shown, in SQL Server Management Studio, to be varchar(100), while the columns in the table are defined as nvarchar(100). There are no CAST or CONVERT statements in the view, it is a simple SELECT statement. Example: Table - Columns: Desc1 (nvarchar(100), null) View - SELECT TOP 100 PERCENT Desc1 FROM... Columns: Desc1 (varchar(100), null) Any ideas why the columns are defined as varchar in the view instead of nvarchar?

• Rails -- Cant set value for date_select in form

  - by ChrisWesAllen

  I'm pulling data from an API where the date data comes in as "2008-02-11 00:00:00 " I would like that data to go into my form within the date_select as a value so I can view it correctly before I add it into my database. The view looks like <%= f.label :start_date %><br /> <%= f.date_select :start_date, :value => " #{@stdate[idx]} " %> The object is actually an array of dates since I'm doing this action several times do thats why the [idx] is there; serving as an index. <%= @stdate[idx] % ends up outputting "2008-02-11 00:00:00 " but the fields for the date_select helper only outputs the current date "2010" "June" "5" in those dropdown date selects fields... Do I need to set the values of the Year, Month, and Date Individually? I have Chronic and tried to parse the object before using it as a value for the date_select and that didnt work either. Any ideas?

• Java: PriorityQueue returning incorrect ordering from custom comparator??

  - by Michael Simpson

  I've written a custom comparator to compare my node classes, but the java priority queue is not returning my items in the correct order. Here is my comparator: public int compare(Node n1, Node n2){ if (n1.getF() > n2.getF()){ return +1; } else if (n1.getF() < n2.getF()){ return -1; } else { // equal return 0; } } Where getF returns a double. However after inserting several Nodes into the priority queue, I print them out using: while(open.size() > 0) { Node t = (Node)(open.remove()); System.out.println(t.getF()); } Which results in: 6.830951894845301 6.830951894845301 6.0 6.0 5.242640687119285 7.4031242374328485 7.4031242374328485 8.071067811865476 Any ideas why this is so? Is my comparator wrong? Thanks. Mike
