• REST destroy link generate problem

  - by Wei

  I am using rails beta 3 and I have a erb page named index.html.erb for discussions controller. In that page, I have a link as following: <%= link_to 'Delete', {:action='destroy', :id=@discussion}, :confirm="Are you sure", :method='post' % Which is supposed to generate a link to delete a discussion, however, the generated html is Delete which always routes to the show action. I think the href should be /discussions/destroy/1. But for some reason it is not. Any ideas? Thanks in advance.

• Problem while redirecting user after registration

  - by Eternal Learner

  I am creating a simple website . My situation is like this. After registering an user, I want to redirect the user after say 3 seconds to a main page(if the registration succeeds) . The code I have now is as below $query = "INSERT INTO Privileges VALUES('$user','$password1','$role')"; $result = mysql_query($query, $dbcon) or die('Registration Failed: ' . mysql_error()); print 'Thanks for Registering , You will be redirected shortly'; ob_start(); echo "Test"; header("Location: http://www.php.net"); ob_flush() I get the error message Warning: Cannot modify header information - headers already sent by (output started at/home/srinivasa/public_html/ThanksForRegistering.php:27) in /home/srinivasa /public_html/ThanksForRegistering.php on line 35.

• Type casting problem with java for-each loop

  - by pharma_joe

  Hi, I have traced an issue with an application I am developing, it is giving me a type cast exception. Funny thing is it is saying it cannot cast "entities.Movie cannot be cast to entities.Movie"?! movies is an ArrayList. try { movies = getMovies(); } catch (Exception e) { e.printStackTrace(System.out); } finally { try { for (Movie movie : movies) { output.append(" <tr>\n"); output.append(" <td>" + movie.getId() + "</td>"); output.append(" </tr>\n"); } } catch (Exception e) { e.printStackTrace(System.out); } }

• How can I fix my window focus problem?

  - by Ben313

  I have a very frustrating bug in an application I am working on. The routine is supposed to do something in one window, and then return focus to the other at the end of the method, but when I started to use a large data set the other day, the focus stopped returning at the end. I stepped through the code one line at a time, and the errors stopped. so, i figure its a timing issue of some kind. I trace through until i find what i suspect is the culprit. A call to ShellExecute(...), that terminates an image editor i use. (http://msdn.microsoft.com/en-us/library/bb762153(VS.85).aspx) Now, if I step past this call, and then continue to run the program, everything works fine, but if I just run past this line, the error occurs. how can this be? I have a call to SetFocus() at the very end of this method. shouldnt the program hit this no matter what? This is all so very frustrating...

• PHP & RSS Feeds & Special Characters validation Problem.

  - by BUGY

  I keep getting the following validation warning below. And I was wondering that some of my articles deal with special characters and was wondering how should I go about rendering or not rendering special characters in my RSS feeds? Should I use htmlentites or not? If so how? In addition, interoperability with the widest range of feed readers could be improved by implementing the following recommendations. line 22, column 35: title should not contain HTML: &amp; PHP code. <title>' . htmlentities(strip_tags($title), ENT_QUOTES, "UTF-8") . '</title>

• jquery ajax problem in chrome

  - by spaceman

  i have the following jquery code running on my page just fine in FF and IE, but chrome seems to be freaking out.. in FF and IE the call is made and the result is appended to the div. in chrome, it calls ajaxfailed on failure. the XMLHttpRequest passed to the AjaxFailed function has a status code of "200" and the statusText is "ok". the readystate is 4 and the responseText is set to the data i wish to append to the div.. basically from what i can see its calling the failure method but it isn't failing.. i have tried with both get and post requests and it always breaks in chrome. function getBranchDetails(contactID, branchID) { $.ajax({ type: "GET", url: urlToRequestTo, data: "{}", contentType: "application/json; charset=utf-8", dataType: "json", success: branchDetailsSuccess, error: AjaxFailed }); } function branchDetailsSuccess(result) { $("#divBranchControl").empty(); $("#divBranchControl").append(" " + result); $("#branchDiv").tabs(); } function AjaxFailed(result) { alert("FAILED : " + result.status + ' ' + result.statusText); }

• Problem running apps fullscreen in emulator

  - by Haakon

  I've created a device targeting 2.1 and having a screen screen size of 480x800 (WVGA). Some apps, including the one I'm currently writing, as well as the ApiDemos example, won't run fullscreen. I've uploaded a screenshot here: http://img248.imageshack.us/img248/503/emulator.png What could cause something like this? If I run these apps on my HTC Desire (which has the same resolution), they utilize the whole screen like they should.

• Problem Making C++ script

  - by Abs

  Hello all, I am not sure if I can post this sort of question (apologies in advance) but I am trying to build something from this blog post. # mkdir wkthumb # cat > wkthumb.cpp # qmake -project # qmake && make # ./wkthumb I have no experience with this, but I download all the files needed in the directory wkthumb using git. I have gone inside this directory and tried to execute cat > wkthumb.cpp - this just hangs for me. In addition, I thought cat was supposed to be used like this: cat file1.txt file2.txt > file3.txt? The above is blank with the first arguments? I am using Fedora Core 10.

• Problem using OLEDBCOMMANDBUILDER.

  - by Lullly

  So, here it goes: I need to copy data from table in access database, in another table from another access database. Column names from tables are the same, except the fact that the FROM table has 5 columns, the TO table has 6. here is my code: dsFrom.Clear() dsTO.Clear() daFrom = Nothing daTO = Nothing conn_string1 = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source="etc.mdb;" conn_string2 = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source="database.mdb;" query1 = "Select * from nomenclator_produse" query2 = "Select * from nomenclator_produse" Conn1 = New OleDbConnection(conn_string1) conn2 = New OleDbConnection(conn_string2) Conn1.Open() conn2.Open() daFrom = New OleDbDataAdapter(query1, Conn1) daTO = New OleDbDataAdapter(query2, conn2) daFrom.AcceptChangesDuringFill = False dsFrom.HasChanges() daFrom.Fill(dsFrom, "nomenclator_Produse") dsFrom.HasChanges() Dim cb = New OleDbCommandBuilder(daFrom) dsTO = dsFrom.Copy daTO.UpdateCommand = cb.GetUpdateCommand daTO.InsertCommand = cb.GetInsertCommand daTO.Update(dsTO, "nomenclator_produse") Because the FROM table has 5 rows and the other has 6, i'm trying to use the InsertCommand generated by the DataAdapter of the first table. It works, only that it inserts the data from the FROMTABLE in the same FROMTABLE, instead of TOTABLE. :| please help me :(

• Problem with Initializing Consts

  This code, when compiled in xlC 8.0 (on AIX 6.1), produces the wrong result. It should print 12345, but instead prints 804399880.

• problem with IN clause in SQL

  - by user179056

  Hello, We have observed that there seems to be a maximum number of ids/variables which one can pass in the IN clause of SQL as comma seperated values. To avoid this we are storing all the ids in a table and doing a SELECT within the IN clause. This however means extra database operations to store and retrieve ids. Is there any other way to use IN without SELECT? regards Sameer

• specifying ThreadPoolExecutor problem

  - by Sarmun

  Is there any way to create Executor that will have always at least 5 threads, and maximum of 20 threads, and unbounded queue for tasks (meaning no task is rejected) I tried new ThreadPoolExecutor(5, 20, 60L, TimeUnit.SECONDS, queue) with all possibilities that I thought of for queue: new LinkedBlockingQueue() // never runs more than 5 threads new LinkedBlockingQueue(1000000) // runs more than 5 threads, only when there is more than 1000000 tasks waiting new ArrayBlockingQueue(1000000) // runs more than 5 threads, only when there is more than 1000000 tasks waiting new SynchronousQueue() // no tasks can wait, after 20, they are rejected and none worked as wanted.

• jQuery $.each()-problem

  - by Volmar

  Hi, im making a wordpress plugin and i have a function where i import images, this is done with a $.each()-loop that calls a .load()-function every iteration. The load-function page the load-function calls is downloading the image and returns a number. The number is imported into a span-element. The source and destination Arrays is being imported from LI-elemnts of a hidden ULs. this way the user sees a counter counting from zero up to the total number of images being imported. You can se my jQuery code below: jQuery(document).ready(function($) { $('#mrc_imp_img').click(function(){ var dstA = []; var srcA = []; $("#mrc_dst li").each(function() { dstA.push($(this).text()) }); $("#mrc_src li").each(function() { srcA.push($(this).text()) }); $.each(srcA, function (i,v) { $('#mrc_imgimport span.fc').load('/wp-content/plugins/myplugin/imp.php?num='+i+'&dst='+dstA[i]+'&src='+srcA[i]); }); }); }); This works pretty good but sometimes it looks like the load function isn't updating the DOM as fast as it should because sometimes the numbers that the span is updated with is lower than the previous and almost everytime a lower number is replacing the last number in the end. How can i prevent this from happening and how can i make it hide '#mrc_imp_img' when the $.each-loop is ready?
