• Error while closing SQL Connection

  - by Wickedman84

  I have a problem with closing the SQLconnection in my application. My application is in VB.net. I have a reference in my application to a class with code to open and close the database connection and to execute all sql scripts. The error occurs when i close my application. In the formClosing event of my main form I call a function that closes all the connections. But just before I close the connections I perform an SQLquery to delete a row from a table with the function below. Public Function DeleteFunction(ByVal mySQLQuery As String, ByVal cmd As SqlCommand) As Boolean Try cmd.Connection = myConnection cmd.CommandText = mySQLQuery cmd.ExecuteNonQuery() Return True Catch ex As Exception WriteErrorMessage("DeleteFunction", ex, Logpath, "SQL Error: " & mySQLQuery) Return False End Try End Function In my application I check the result of the boolean. If it returns True, then i call the function to close the database connection. The returned boolean is True and the requested row is deleted in my database. This means i can close my connection which I do with the function below. Public Sub DatabaseConnClose() myCommand.CommandText = "" myConnection.Close() myCommand = Nothing myConnection = Nothing End Sub After executing this code I receive an error in my logfile from the DeleteFunction. It says: "Connection property has not been initialized." It seems very strange to receive an error from a function that was completely executed, or am i wrong to think that? Can anyone tell me why I receive this error and how I can solve the problem?

• When destroying one record, another one gets destroyed

  - by normalocity

  Products (like an iPod Classic) :has_many = :listings, :dependent = :destroy Listings (like "My name is Joe, and I have an iPod for sale) :belongs_to = :product So, if I delete a given Product, all the listings that point to it get deleted. That makes sense, and is by design. However, I am writing a "merge" function, where you merge two Products into one, and combine their Listings. So, let's say my two products are "iPod Color" and "iPod Classic", and I want to merge the two. What I want to do is say, "iPod Color, merge into iPod Classic", and result should be that: All the iPod Color Listings are re-pointed to the iPod Classic product After the product_id change, the Listing(s) are saved I then delete the "iPod Color" product Well, that should all work fine, without deleting any Listings. However, I've got this controller, and for whatever reason when I destroy the "iPod Color" Product, even after confirming that the Listings have been moved to "iPod Classic" and saved to the database, the Listings that were previously pointed to "iPod Color" get destroyed as well, and I can't figure out why. It's as if they are retaining some kind of link to the destroyed product, and therefore begin destroyed themselves. What painfully obvious thing am I missing? def merge merging_from = Product.find(params[:id]) merging_to = Product.find_by_model(params[:merging_to]) unless merging_to.nil? unless merging_from.nil? unless merging_from == merging_to # you don't want to merge something with itself merging_from.listings.each do |l| l.product = merging_to l.save end # through some debugging, I've confirmed that my missing Listings are disappearing as a result of the following destroy call merging_from.destroy end end end

• c++ overloading delete, retrieve size

  - by user300713

  Hi, I am currently writing a small custom memory Allocator in c++, and want to use it together with operator overloading of new/delete. Anyways, my memory Allocator basicall checks if the requested memory is over a certain threshold, and if so uses malloc to allocate the requested memory chunk. Otherwise the memory will be provided by some fixedPool allocators. that generally works, but for my deallocation function looks like this: void MemoryManager::deallocate(void * _ptr, size_t _size){ if(_size heapThreshold) deallocHeap(_ptr); else deallocFixedPool(_ptr, _size); } so I need to provide the size of the chunk pointed to, to deallocate from the right place. No the problem is that the delete keyword does not provide any hint on the size of the deleted chunk, so I would need something like this: void operator delete(void * _ptr, size_t _size){ MemoryManager::deallocate(_ptr, _size); } But as far as I can see, there is no way to determine the size inside the delete operator.- If I want to keep things the way it is right now, would I have to save the size of the memory chunks myself? Any ideas on how to solve this are welcome! Thanks!

• Java Hibernate session delete of object

  - by user2535201

  I'm really struggling with hibernate sessions, I never have the result I expect when making a query on a modified session object. I think all my problems are related. The last one is the following : final Session iSession = AbstractDAO.getSessionFactory().openSession(); try { iSession.beginTransaction(); MyObject iObject = DAOMyObject.getInstance().get(iSession,ObjectId); iObject.setQuantity(0); //previously the quantity was different from zero DAOMyObject.getInstance().update(iSession,iObject); DAOMyObject.getInstance().deleteObjectWithZeroQuantities(iSession); iSession.getTransaction().commit(); } catch (final Exception aException) { iSession.getTransaction().rollback(); logger.error(aException.getMessage(), aException); throw aException; } finally { iSession.close(); } What I'm not getting is why the object is not deleted, since I'm modified it in the session, the query making the delete should find it. I had the same problem with creating an object with an incremental id in a session, then creating another one in the same session before the commit, with a select max(id)+1. But the session gets me the same number of id every time.

• How can I retain the data stored in plist from UITextField when application is restarted ?

  - by srikanth rongali

  I am using the plist to store the data entered in the UITextFields. But, when I restart my application all the data entered previously was deleted. How can I retain the data in the Plist. I have a UITableView and when a cell is touched a view appears with two UITextFields. nameField and descriptionField. I stored the data in this way. My code is. -(void)save:(id)sender { indexOfDataArray = temp; //the cell selected in table view. NSString *string1 = [[NSString alloc]init]; NSString *string2 = [[NSString alloc]init]; string1 = nameField.text; string2 = descriptionField.text; NSDictionary *myDict = [[NSDictionary alloc] initWithObjectsAndKeys:string2, string1, nil]; [myArray addObject:myDict]; //myArray is NSMutableArray declared in tableViewController class. //[myArray insertObject:myDict atIndex:indexOfDataArray]; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *path = [documentsDirectory stringByAppendingPathComponent:@"tableVideoData.plist"]; [myArray writeToFile:path atomically:YES]; UIAlertView *alertMesage = [[UIAlertView alloc] initWithTitle: @"Save Alert" message:@"The data entered is saved" delegate:nil cancelButtonTitle:@"cancel" otherButtonTitles:nil] ; [alertMesage show]; [alertMesage release]; } When I am using the [myArray insertObject:myDict atIndex:indexOfDataArray]; It is giving the error *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSCFArray insertObject:atIndex:]: index (2) beyond bounds (1)' So I used [myArray addObject:myDict]; Please help me, how can I retain the data in plist.

• Paypal Sandbox 2014 Non US test account Sign Up proper link

  - by Flood Gravemind

  Ok I had a Paypal Sandbox account a year ago. I am developing a new site for a client and when I try to Login it won't recognize my email address. I tried forgot my password forgot password still nothing. So I guessed that maybe due to inactivity for such a long time they may have deleted my account. So then I try to Sign Up for a new one. I entered my details 3 times now and spent 6 hours trying to figure out what is the proper link to do this. Then I went to another Sandbox link which required me to entered a US Zip code and its a dead end. I am not even sure which Paypal account I signed up for those three times. No email nothing at all. I am a Non US developer and the FAQ link for Non US developers just points to their REST API. Can someone please guide me to the proper Paypal Sandbox Setup for Non US developers including the proper sign up links please. And I know Stackoverflow does not like rants but from my experience dealing with Paypal, GTA 6 should make a satirical Paypal company in their next Game with Paypal Developer Rampage mode for the main protagonist who also happens to be a Developer. EDIT: REST API does not include UK :(

• Taking wrong database configuration array

  - by user309076

  Hi, I have one application in which i have used 2 database connections. In my database config file i have given two arrays as below. $active_group = ‘default’; $active_record = TRUE; FIRST ARRAY $db[‘default’][‘hostname’] = ‘hostname’; .............. .......... SECOND ARRAY $db[‘another_db’][‘hostname’] = ‘hostname’; .............. .......... this is working fine. Now, I copied the entire CI folder to develop another application in which only one database connection needed. So, now, in the database config file, i deleted the second configuration array. But, the db class is taking first application’s second array i.e. “another_db” and it is giving the below error. “You have specified an invalid database connection group.” When i change the default (only one) array name to “another_db” in configuration file. It is working fine. Can’t understand from where it is taking the group name as “another_db”. My application autoloads database library. I have debugged the ci_auto_loader in Loader.php class where it calls $this-database() function with no parameters. But in function database($params, $, $) {}, if I echo $params it shows “another_db”.

• Best tree/heap data structure for fixed set of nodes with changing values + need top 20 values?

  - by user350139

  I'm writing something like a game in C++ where I have a database table containing the current score for each user. I want to read that table into memory at the start of the game, quickly change each user's score while the game is being played in response to what each user does, and then when the game ends write the current scores back to the database. I also want to be able to find the 20 or so users with the highest scores. No users will be added or deleted during the short period when the game is being played. I haven't tried it yet, but updating the database might take too much time during the period when the game is being played. Fixed set of users (might be 10,000 to 50,000 users) Will map user IDs to their score and other user-specific information. User IDs will be auto_increment values. If the structure has a high memory overhead that's probably not an issue. If the program crashes during gameplay it can just be re-started. Quickly get a user's current score. Quickly add to a user's current score (and return their current score) Quickly get 20 users with highest score. No deletes. No inserts except when the structure is first created, and how long that takes isn't critical. Getting the top 20 users will only happen every five or ten seconds, but getting/adding will happen much more frequently. If not for the last, I could just create a memory block equal to sizeof(user) * max(user id) and put each user at user id * sizeof(user) for fast access. Should I do that plus some other structure for the Top 20 feature, or is there one structure that will handle all of this together?

• How do I import facebook friends from another website

  - by Jim Zimmerman

  I am looking for a way to connect to facebook by allowing the user to enter in their username and password and have our app connect to their account and get their contacts so that they can invite them to join their group on our site. I have written a facebook app before, but this is not an app as much as it is a connector so that they can invite all their friends or just some to the site we are working on. I have seen several other sites do this and also connect to Yahoo, Gmail and Hotmail contacts. I dont think they are using Facebook Connect to do this since it is so new, but they may be. Any solution in any language is fine as I can port whatever example to use C#. I cannot find anything specifically on Google or Facebook to address this specific problem. Any help is appreciated. I saw a first answer get removed that had suggested i might need to scrape the friends page. The more I look around, this might be what i need to do. Any other way i think will require the person to add it as an app. I am wondering how a answer can get removed, maybe that user deleted it.

• Why might this work on my server but not my schools?

  - by Doug

  I created a captcha just now, and it works PERFECTLY on my own server. On the school's server, it doesn't generate an image. Why might this be? The difference in code is one line. *Edit:*Originally, it was working, but I deleted the directory by mistake and I do not know why did it suddenly work in the first place. Source code on school server: <?php session_save_path("/ichanged/this/path/for/this/post/"); session_start(); $img=imagecreatefromjpeg("bg.jpg"); if( empty($_SESSION['captcha_numbers']) ) { $captcha_numbers = 'error'; } else { $captcha_numbers = $_SESSION['captcha_numbers']; } $image_numbers=$captcha_numbers; $red=rand(100,150); $green=rand(100,255); $blue=rand(100,255); $color=imagecolorallocate($img,255-$red,255-$green,255-$blue); $text=imagettftext($img,12,rand(-7,7),rand(10,20),rand(20,30),$color,"fonts/M04.TTF",$image_numbers); header("Content-type:image/jpeg"); header("Content-Disposition:inline ; filename=secure.jpg"); imagejpeg($img); ?> Source code on my server: <?php session_start(); $img=imagecreatefromjpeg("bg.jpg"); if( empty($_SESSION['captcha_numbers']) ) { $captcha_numbers = 'error'; } else { $captcha_numbers = $_SESSION['captcha_numbers']; } $image_numbers=$captcha_numbers; $red=rand(100,150); $green=rand(100,255); $blue=rand(100,255); $color=imagecolorallocate($img,255-$red,255-$green,255-$blue); $text=imagettftext($img,12,rand(-7,7),rand(10,20),rand(20,30),$color,"fonts/M04.TTF",$image_numbers); header("Content-type:image/jpeg"); header("Content-Disposition:inline ; filename=secure.jpg"); imagejpeg($img); ?>

• Image does not update when file name remains the same in XCode 3.1.2

  - by vman049

  Hi Everyone, I'm using XCode version 3.1.2 and am developing for iPhone using the Simulator with iOS 2.2.1 on Leopard. I had an image file named "img.jpg" in my project which I decided to switch for a different file. After adding the new file into the XCode Resources folder, I removed the first file and renamed the new file to the same name as the previous one, "img.jpg." When I run my program, however, the Simulator loads the old image instead of the new one, even though the old one has been deleted from disk (not just the reference). I tried changing the name of the file to "img2.jpg," and it worked like it should - loading the new image, but I want to keep the name "img.jpg." I ran a search with Spotlight for "img.jpg" to see if there was another copy stored somewhere that XCode was using, but it only returned my new image file. I have tried uninstalling the app from the Simulator and running the application again, but that also does not fix the problem. What must I do for XCode to recognize that I want to use the new image file and not the old one? Thanks for your help!!

• How to set up site specific configuration vs application configuration in Zend Framework?

  - by rbruhn

  Being fairly new to Zend Framework, I've been reading and trying out various tutorials on the web and books I've purchased. One thing all the tutorials do is hard code certain values into into the bootstrap or other code. For example, setting the title: $this-_view-headTitle('MySite'); I realize this can be set in the application.ini file, but I don't think that is appropriate either if you are distributing the application to other sites. I would be interested in hearing ideas where application specific settings are set in the application.ini file and loaded: $application = new Zend_Application( APPLICATION_ENV, APPLICATION_PATH.'/configs/application.ini' ); Then somewhere in the bootstrap, checking for a config.ini file and adding these to currently existing application config array, and if config.ini does not exist, retrieving such site specific configs from a database and writing the config.ini file (Obviously the file deleted and rewritten if a value is changed in the database). I don't need to see how the file is written or what not... just a general idea of how others are handling such things. Or provide different ideas of doing this? I would rather end up using something like this when setting various site specific configurations: $this->_view->headTitle($config->site->title); Hope this makes sense :-)

• Unable to Connect to Management Studio Server

  - by Phil Hilliard

  I have a nasty situation. I am using Microsoft SQL Server Management Studio Express edition locally on my pc for testing, and once tested I upload database changes to a remote server. I have a situation where I deleted the Default Database on my local machine, and instead of searching hard enough to find an answer to that problem, I uninstalled and reinstalled Management Studio. Since then Management Studio has not been able to connect to the server. Is there any help (or hope for me for that matter), out there????? The following is the detailed error message: =================================== Cannot connect to LENOVO-E7A54767\SQLEXPRESS. =================================== A network-related or instance-specific error occurred while establishing a connection to SQL Server.

• Configuration Error , Finding assembly after I swapped referenced dll out. Visual Studio 2003

  - by TampaRich

  Here is the situation. I had a clean build of my asp.net web application working. I then went into the bin folder under the web app and replaced two referenced dll's with two older version of the same dll's. (Same name etc.) After testing I replaced those dll's back to the new ones and now my application keeps throwing the configuration error === Pre-bind state information === LOG: DisplayName = xxxxx.xxxx.Personalization (Partial) LOG: Appbase = file:///c:/inetpub/wwwroot/appname LOG: Initial PrivatePath = bin Calling assembly : (Unknown). LOG: Policy not being applied to reference at this time (private, custom, partial, or location-based assembly bind). I found this issue on the web and tried all the solutions to it but nothing worked. I then went into all my projects that it references under the solution and cleared out the bin/debug folder in each, I cleared out the obj folder under each and also deleted the temporary files associated with the application. I rebuilt it and it still will not work due to this error Not sure what is causing this or how to fix this issue. I have tried restarting IIS, stopping index services which was said to be a known issue. This is .net framework 1.1 app and visual studio 2003 Any suggestions would be great. Thanks.

• [PHP/MySQL] How to create text diff web app

  - by Adam Kiss

  Hello, idea I would like to create a little app for myself to store ideas (the thing is - I want it to do MY WAY) database I'm thinking going simple: id - unique id of revision in database text_id - identification number of text rev_id - number of revision flags - various purposes - expl. later title - self expl. desc - description text - self expl . flags - if I (i.e.) add flag rb;65, instead of storing whole text, I just said, that whenever I ask for latest revision, I go again in DB and check revision 65 Question: Is this setup the best? Is it better to store the diff, or whole text (i know, place is cheap...)? Does that revision flag make sense (wouldn't it be better to just copy text - more disk space, but less db and php processing. php I'm thinking, that I'll go with PEAR here. Although main point is to open-edit-save, possiblity to view revisions can't be that hard to program and can be life-saver in certain situations (good ideas got deleted, saving wrong version, etc...). However, I've never used PEAR in a long-time or full-project relationship, however, brief encounters in my previous experience left rather bad feeling - as I remember, it was too difficult to implement, slow and humongous to play with, so I don't know, if there's anything better. why? Although there are bazillions of various time/project/idea management tools, everything lacks something for me, whether it's sharing with users, syncing on more PCs, time-tracking, project management... And I believe, that this text diff webapp will be for internal use with various different tools later. So if you know any good and nice-UI-having project management app with support for text-heavy usage, just let me know, so I'll save my time for something better than redesigning the weel.

• Hibernate many-to-many relationship

  - by Capitan

  I have two mapped types, related many-to-many. @Entity @Table(name = "students") public class Student{ ... @ManyToMany(fetch = FetchType.EAGER) @JoinTable( name = "students2courses", joinColumns = { @JoinColumn( name = "student_id", referencedColumnName = "_id") }, inverseJoinColumns = { @JoinColumn( name = "course_id", referencedColumnName = "_id") }) public Set<Course> getCourses() { return courses; } public void setCourses(Set<Course> courses) { this.courses = courses; } ... } __ @Entity @Table(name = "courses") public class Course{ ... @ManyToMany(fetch = FetchType.EAGER, mappedBy = "courses") public Set<Student> getStudents() { return students; } public void setStudents(Set<Student> students) { this.students = students; } ... } But if I update/delete Course entity, records are not created/deleted in table students2courses. (with Student entity updating/deleting goes as expected) I wrote abstract class HibObject public abstract class HibObject { public String getRemoveMTMQuery() { return null; } } which is inherited by Student and Course. In DAO I added this code (for delete() method): String query = obj.getRemoveMTMQuery(); if (query != null) { session.createSQLQuery(query).executeUpdate(); } and I ovrerided method getRemoveMTMQuery() for Course @Override @Transient public String getRemoveMTMQuery() { return "delete from students2courses where course_id = " + id + ";"; } Now it works but I think it's a bad code. Is there a best way to solve this problem?

• Best way to do one-to-many "JOIN" in CouchDB

  - by mit

  There are CouchDB documents that are list elements: { "type" : "el", "id" : "1", "content" : "first" } { "type" : "el", "id" : "2", "content" : "second" } { "type" : "el", "id" : "3", "content" : "third" } There is one document that defines the list: { "type" : "list", "elements" : ["2","1"] , "id" : "abc123" } As you can see the third element was deleted, it is no longer part of the list. So it must not be part of the result. Now I want a view that returns the content elements including the right order. The result could be: { "content" : ["second", "first"] } In this case the order of the elements is already as it should be. Another possible result: { "content" : [{"content" : "first", "order" : 2},{"content" : "second", "order" : 1}] } I started writing the map function: map = function (doc) { if (doc.type === 'el') { emit(doc.id, {"content" : doc.content}); //emit the id and the content exit; } if (doc.type === 'list') { for ( var i=0, l=doc.elements.length; i<l; ++i ){ emit(doc.elements[i], { "order" : i }); //emit the id and the order } } } This is as far as I can get. Can you correct my mistakes and write a reduce function? Remember that the third document must not be part of the result. Of course you can write a different map function also. But the structure of the documents (one definig element document and an entry document for each entry) cannot be changed.

• Different output between release and Debug

  - by AthomSfere

  I can't figure this one out. I have a c++ Application that works in Debug mode exactly as expected: #include "stdafx.h" #include <string> #include <Windows.h> #include <iostream> using namespace std; void truncateServer(std::string inString); int _tmain(int argc, char *argv[]) { char* server = argv[1]; truncateServer(server); } void truncateServer(std::string inString) { std::string server = ""; int whackCount = 0; for (unsigned int i = 0; i < inString.length(); i++) { char c = inString[i]; if (whackCount < 3) { if (c == '\\') whackCount++; else server += c; } } cout << server; } For example if I call the server I want via its UNC path \\serverName\Share\ in the debug it gives me exactly what I want: servername However, if I use the release build I get nothing: I deleted the release output folder, but the issue is exactly the same. I can only assume there is some other difference between the release and build applications that is exposing a major issue with my code? Or another difference between the outputs I need to account for. What do I need to do to get the expected output?

• How can I remove all users in an Active Directory group?

  - by Beavis

  I'm trying to remove all users from an AD group with the following code: private void RemoveStudents() { foreach (DirectoryEntry childDir in rootRefreshDir.Children) { DirectoryEntry groupDE = new DirectoryEntry(childDir.Path); for (int counter = 0; counter < groupDE.Properties["member"].Count; counter++) { groupDE.Properties["member"].Remove(groupDE.Properties["member"][counter]); groupDE.CommitChanges(); groupDE.Close(); } } } The rootRefreshDir is the directory that contains all the AD groups (childDir). What I'm finding here is that this code does not behave correctly. It removes users, but it doesn't do it after the first run. It does "some". Then I run it again, and again, and again - depending on how many users need to be deleted in a group. I'm not sure why it's functioning this way. Can someone help fix this code or provide an alternative method to delete all users in a group? Thanks!

• Is there a free tool which can help visualize the logic of a stored procedure in SQL Server 2008 R2?

  - by Hamish Grubijan

  I would like to be able to plot a call graph of a stored procedure. I am not interested in every detail, and I am not concerned with dynamic SQL (although it would be cool to detect it and skip it maybe or mark it as such.) I would like the tool to generate a tree for me, given the server name, db name, stored proc name, a "call tree", which includes: Parent stored procedure. Every other stored procedure that is being called as a child of the caller. Every table that is being modified (updated or deleted from) as a child of the stored proc which does it. Hopefully it is clear what I am after; if not - please do ask. If there is not a tool that can do this, then I would like to try to write one myself. Python 2.6 is my language of choice, and I would like to use standard libraries as much as possible. Any suggestions? EDIT: For the purposes of bounty Warning: SQL syntax is COMPLEX. I need something that can parse all kinds of SQL 2008, even if it looks stupid. No corner cases barred :) EDIT2: I would be OK if all I am missing is graphics.

• UpdatePanel doesn't Refresh

  - by mrxrsd

  I have got a simple page with a HtmlInputHidden field. I use Javascript to update that value and, when posting back the page, I want to read the value of that HtmlInputHidden field. The Value property of that HtmlInputHidden field is on postback the default value (the value it had when the page was created, not the value reflected through the Javascript). I also tried to Register the HtmlInputHidden field with ScriptManager.RegisterHiddenField(Page, "MyHtmlImputHiddenField", "initialvalue") but it still only lets me read the 'initialvalue' even though I (through javascript) can inspect that the value has changed. I tried to hardcoded the rowid and, to my surprise, after postback gridview was exactly the same before the delete but the record was deleted from the database. (I´ve called the databind method). protected void gridViewDelete(object sender, GridViewDeleteEventArgs e) { bool bDelete = false; bool bCheck = false; if (hfControl.Value != "1") { // check relationship bCheck = validation_method(.......); if (bCheck) { bDelete = true; } } else { hfControl.Value = ""; bDelete = true; } if (bDelete) { //process delete } else { string script = string.Empty; script += " var x; "; script += " x = confirm('are u sure?'); "; script += " if (x){ " ; script += " document.getElementById('hfControl').value = '1'; "; script += " setTimeOut(__doPostBack('gridView','Delete$" + e.RowIndex + "'),0);"; script += " } "; ScriptManager.RegisterClientScriptBlock(this, Page.GetType() , "confirm" , script ,true); } }

  Hi! I've got a JPA entity "Request", that owns a List of Answers (also JPA entities). Here's how it's defined in Request.java: @OneToMany(cascade= CascadeType.ALL, mappedBy="request") private List<Answer> answerList; And in Answer.java: @JoinColumn(name = "request", referencedColumnName="id") @ManyToOne(optional = false) private Request request; In the course of program execution, the Request's List of Answers may have Answers added or removed from it, or the actual List object may be replaced. My problem is thus: when I merge a Request to the database, the Answer objects that used to be in the List are kept in the database -- that is, Answer objects that the Request no longer holds a reference to (indirectly, via a List) are not deleted. This is not the behaviour I desire, as if I merge a Request to the database, and then fetch it again, its Answers List may not be the same. Am I making some programming mistake? Is there an annotaion or setting that will ensure that the Answers in the database are exactly the Answers in the Request's List? A solution is to keep references to the original Answers List and then use the EntityManager to remove each old Answer before merging the Request, but it seems like there should be a cleaner way. Thank you!

• CakePHP: Missing database table

  - by Justin

  I have a CakePHP application that is running fine locally. I uploaded it to a production server and the first page that uses a database connection gives the "Missing Database Table" error. When I look at the controller dump, it's complaining about the first table. I've tried a variety of things to fix this problem, with no luck: I've confirmed that at the command line I can login with the given MySQL credentials in database.php I've confirmed this table exists I've tried using the MySQL root credentials (temporarily) to see if the problem lies with permissions of the user. The same error appeared. My debug level is currently set to 3 I've deleted the entire contents of /app/tmp/cache I've set 777 permissions on /app/tmp* I've confirmed that I can run DESCRIBE commands at the commant line MySQL when logged in with the MySQL credentials used by by the application I've verified that the CakePHP log file only contains the error I'm setting in the browser window. I've tried all the suggestions I could find in similar postings on SO I've Googled around and didn't find any other ideas I think I've eliminating the obvious problems and my research isn't turning anything up. I feel like I'm missing something obvious. Any ideas?

• CPU overheating because of Delphi IDE

  - by Altar

  I am using Delphi 7 but I have trialed the Delphi 2005 - 2010 versions. In all these new versions my CPU utilization is 50% (one core is 100%, the other is "relaxed") when Delphi IDE is visible on screen. It doesn't happen when the IDE is minimized. My computer is overheating because of this. Any hints why this happens? It looks like if I want to upgrade to Delphi 2010, I need to upgrade my cooling system first. And I am a bit lazy about that, especially that I want to discahrge my computer and buy a new one (in the next 6 months) - probably I will have to buy a Win 7 license too. Edit: My CPU is AMD Dual Core 4600+. 4GB RAM Overheating means that temperature of the HDDs is raising because the CPU. Edit: Comming to a possible solution I just deleted all HKCU/CodeGear key and let started Delphi as "new". Guess what? The CPU utilization is 0%. I will investigate more.

• AS3 colorTransform over multiple frames?

  - by user359519

  (Flash Professional, AS3) I'm working on a custom avatar system where you can select various festures and colors. For example, I have 10 hairstyles, and a colorPicker to change the color. mc_myAvatar has 10 frames. Each frame has a movieclip of a different hairstyle (HairStyle1, HairStyle2, etc.) Here's my code: var hairColor:ColorTransform; hairColor = mc_myAvatar.hair.colorLayer.transform.colorTransform; hairColor.color = 0xCCCC00; mc_myAvatar.hair.colorLayer.transform.colorTransform = hairColor; This correctly changes the initial color. I have a "nextHair" button to advance mc_myAvatar.hair to the next frame. When I click the button, I get an error message saying that I have a null object reference. I added a trace, and mc_myAvatar.hair.colorLayer is null on frame 2. Why??? I've clearly named HairStyle2 as "colorLayer" in frame 2. I think the problem is related to me using the same name for different classes/movieclips, but I don't know how to fix the problem... I added a square movieclip below my hairStyle movieclips, named the square "colorLevel", and deleted the name from my hairStyle clips. When I click the next button, the square correctly maintains the color from frame to frame. However, having a square doesn't do me much good. :( I tried converting the hairStyle layer to a mask. Doing this, however, results in yet another "null object" error - mc_myAvatar.hair.colorLayer is null after frame 1. I even tried "spanning" my colorLevel across all frames (no keyframes), thinking that this would give me just one movieclip to work with. No luck. Same error! What's going on, here? Why am I getting these null objects, when they are clearly defined in my movieclip? I'm also open to suggestions on a better way to do multiple frames and colors.
