  • Long overdue (for me) question about disposing managed objects in .Net, VB.Net, C#

    - by Jules
    I can't believe I'm still confused about this but, any way, lets finally nail it: I have a class that overrides OnPaint to do some drawing. To speed things up, I create the pens, brushes etc before hand, in the construtor, so that OnPaint does not need to keep creating and disposing them. Now, I make sure that I always dispose of such objects, but I have the feeling I don't need to because, despite the fact they implement IDisposable, they're managed objects. Is this correct?

  • Running your own GAE server

    - by h2g2java
    The question http://stackoverflow.com/questions/2505265/how-difficult-is-it-to-migrate-away-from-google-app-engine triggered me to think about this issue again. I have read of someone running, production-wise, Google app engine development version on their own server. My questions are: Are there any security issues running GAE development on your own server in production mode and exposing it to the www? If so how to mitigate them? Can GAE dev be run on Amazon? Is it possible to port my GAE apps running on Google servers to a GAE running on Amazon, without code changes, but without changing any reference in using other gdata services such as google docs, youtube, gmail, etc. How to configure GAE dev server to use my own hadoop? Or to use Amazon's hadoop?

  • How to quickly search an array of objects in Objective-C

    - by randombits
    Is there a way in Objective-C to search an array of objects by the contained object's properties if the properties are of type string? For instance, I have an NSArray of Person objects. Person has two properties, NSString *firstName and NSString *lastName. What's the best way to search through the array to find everyone who matches 'Ken' anywhere in the firstName OR lastName properties?

  • Java Robot key activity seems to stop working while certain software is running

    - by Mike Turley
    I'm writing a Java application to automate character actions in an online game overnight (specifically, it catches fish in Final Fantasy XI). The app makes heavy use of java's Robot class both for emulating user keyboard input and for detecting color changes on certain parts of the screen. It also uses multithreading and a swing GUI. The application seems to work perfectly when I test it without the game running, just using screenshots to trigger the apps responses into notepad. But for some reason, when I actually launch FFXI and start the program, all of my keyboard and mouse manipulations just stop working altogether. The program is still running, and the Robot class is still able to read pixel colors. But Robot.keyPress, Robot.keyRelease, Robot.mouseMove, Robot.mousePress and Robot.mouseRelease all do nothing. It's the strangest thing-- to test it, I wrote a simple loop that just keeps typing letters, and focused notepad. I'd then start the game, refocus notepad, and it would do nothing. Then I'd exit the game, and it'd start working again immediately. Has anyone else come across something like this, where specific software will stop certain functions of java from working? Also, to make this more interesting-- Last year I wrote a very similar program using the same classes and programming techniques to automate healing a party in the game as they fight. Last year, this program worked perfectly. After running into these problems I dug up that old program, ran it without making any changes, and found that it too was having the same problems. The only differences between now and when it was working: I was running Windows Vista and now I'm running Windows 7, and several new Java versions as well as FFXI versions have been released. What the hell is going on? (if anyone needs to see my source code, email me at [email protected]. I'm trying to keep it to myself.)

  • Testing for undefined and null child objects in ActionsScript/Flex

    - by dbasch
    Hi Everyone, I use this pattern to test for undefined and null values in ActionScript/Flex : if(obj) { execute() } Unfortunately, a ReferenceError is always thrown when I use the pattern to test for child objects : if(obj.child) { execute() } ReferenceError: Error #1069: Property child not found on obj and there is no default value. Why does testing for child objects with if statements throw a ReferenceError? Thanks!

  • Connecting to external MySQL DB from a web server not running MySQL

    - by jrb04c
    While I've been working with MySQL for years, this is the first time I've run across this very newbie-esq issue. Due to a client demand, I must host their website files (PHP) on a IIS server that is not running MySQL (instead, they are running MSSQL). However, I have developed the site using a MySQL database which is located on an external host (Rackspace Cloud). Obviously, my mysql_connect function is now bombing because MySQL is not running on localhost. Question: Is it even possible to hit an external MySQL database if localhost is not running MySQL? Apologies for the rookie question, and many thanks in advance.

  • Microsoft Entourage/Exchange Server problem: all objects disappeared from server - still in some for

    - by splattne
    One of our employees works with Entourage on his MacBook Pro (OSX 10.6) accessing Exchange Server 2007. Last Friday morning, I think while working over a VPN, Entourage (I think it was Entourage) deleted all his objects (mail, calendar, contacts) on the server and while creating a lot of strange folders (starting with underscores) on the client. The local data seems to be there, but not in a consistent form. Since the user's mailbox is rather big, I suspect, that there was some kind of "move" operation which did not complete. I tried to export the data, but the export stops because of a corrupted object. Is there a tool or another way to export or retrieve the local data? Edit - FYI: we solved the problem getting his data from the previous night's backup.

  • Does anyone know how to detect whether a Windows Service is running through Java

    - by GKelly
    There's plenty of information on running Java apps as services, but I need to know how to detect whether a windows service is running or not. Does anyone know how??? At the DOS prompt, I can run: tasklist /svc|findstr "NonRunningService" echo Return code for N onRunningService is %ERRORLEVEL% tasklist /svc|findstr "RunningService" echo Return code for RunningService is %ERRORLEVEL% I get the following: Return code for NonRunningService is 1 Return code for RunningService is 0 In code, I have: int retCode = Runtime.getRuntime.exec("tasklist /svc|findstr \"NonRunningService\"").waitFor(); System.out.println("Return code for NonRunningService is " + retCode); retCode = Runtime.getRuntime.exec("tasklist /svc|findstr \"RunningService\"").waitFor(); System.out.println("Return code for RunningService is " + retCode); I get the following output Return code for NonRunningService is 1 Return code for RunningService is 1 According to the JavaDocs, the waitFor() should block until the process finishes, and give me the exit value of the process. I've also tried using the Process/ProcessBuilder command line calls: //'tasklist /nh /fi "SERVICES eq RunningService"' will return a line for // each running service of the requested type. Process p1 = new ProcessBuilder("tasklist", "/nh", "/fi" "SERVICES eq RunningService").start(); p1.waitFor(); BufferedReader is = new BufferedReader(new InputStreamReader(p1.getInputStream())); String line = is.readLine(); System.out.println("Service - " + line); System.out.println("Running? ", (line==null?"No":"Yes"); gives: Service - Running? No even when I get lines in the output at the command line!

  • Can't change user security on folder - Business Objects XI 3.1

    - by Chris W
    I've got a single folder within the list of All Folders that I can't change any user permissions on. I'm logged in as an admin and when I view security for the folder it says I have full rights to the folder yet i can't change anything on it or it's sub folders even though it clearly shows me as having rights to "Modify the rights users have to objects". As a test I added a new sub-folder called Test which created ok but I'm not able to then delete the sub folder or change it's permissions either. Interestingly we changed permissions on one sub-folder last week without issue but when I check that folder today I now can't update it. Any ideas anyone?

  • Data Access Layer - static list objects and caching

    - by Truegilly
    Hello, i am devloping a site using .net MVC i have a data access layer which basically consists of static list objects that are created from data within my database. The method that rebuilds this data first clears all the list objects. Once they are empty it then add the data. Here is an example of one of the lists im using. its a method which generates all the UK postcodes. there are about 50 methods similar to this in my application that return all sorts of information, such as towns, regions, members, emails etc. public static List<PostCode> AllPostCodes = new List<PostCode>(); when the rebuild method is called it first clears the list. ListPostCodes.AllPostCodes.Clear(); next it re-bulilds the data, by calling the GetAllPostCodes() method /// <summary> /// static method that returns all the UK postcodes /// </summary> public static void GetAllPostCodes() { using (fab_dataContextDataContext db = new fab_dataContextDataContext()) { IQueryable AllPostcodeData = from data in db.PostCodeTables select data; IDbCommand cmd = db.GetCommand(AllPostcodeData); SqlDataAdapter adapter = new SqlDataAdapter(); adapter.SelectCommand = (SqlCommand)cmd; DataSet dataSet = new DataSet(); cmd.Connection.Open(); adapter.FillSchema(dataSet, SchemaType.Source); adapter.Fill(dataSet); cmd.Connection.Close(); // crete the objects foreach (DataRow row in dataSet.Tables[0].Rows) { PostCode postcode = new PostCode(); postcode.ID = Convert.ToInt32(row["PostcodeID"]); postcode.Outcode = row["OutCode"].ToString(); postcode.Latitude = Convert.ToDouble(row["Latitude"]); postcode.Longitude = Convert.ToDouble(row["Longitude"]); postcode.TownID = Convert.ToInt32(row["TownID"]); AllPostCodes.Add(postcode); postcode = null; } } } The rebuild occurs every 1 hour. this ensures that every 1 hour the site will have fresh set of cached data. the issue ive got is that occasionally if during a rebuild, the server will be hit by a request and an exception is thrown. The exception is "Index was outside the bounds of the array." it is due to when a list is being cleared. ListPostCodes.AllPostCodes.Clear(); - // throws exception - although its not always in regard to this list. Once this exception is thrown application dies, All users are affected. I have to restart the server to fix it. i have 2 questions... If i utilise caching instead of static objects would this help ? Is there any way i can say "while the rebuild is taking place, wait for it to complete until accepting requests" any help is most appricaiated ;) truegilly

  • Long running transactions with Spring and Hibernate?

    - by jimbokun
    The underlying problem I want to solve is running a task that generates several temporary tables in MySQL, which need to stay around long enough to fetch results from Java after they are created. Because of the size of the data involved, the task must be completed in batches. Each batch is a call to a stored procedure called through JDBC. The entire process can take half an hour or more for a large data set. To ensure access to the temporary tables, I run the entire task, start to finish, in a single Spring transaction with a TransactionCallbackWithoutResult. Otherwise, I could get a different connection that does not have access to the temporary tables (this would happen occasionally before I wrapped everything in a transaction). This worked fine in my development environment. However, in production I got the following exception: java.sql.SQLException: Lock wait timeout exceeded; try restarting transaction This happened when a different task tried to access some of the same tables during the execution of my long running transaction. What confuses me is that the long running transaction only inserts or updates into temporary tables. All access to non-temporary tables are selects only. From what documentation I can find, the default Spring transaction isolation level should not cause MySQL to block in this case. So my first question, is this the right approach? Can I ensure that I repeatedly get the same connection through a Hibernate template without a long running transaction? If the long running transaction approach is the correct one, what should I check in terms of isolation levels? Is my understanding correct that the default isolation level in Spring/MySQL transactions should not lock tables that are only accessed through selects? What can I do to debug which tables are causing the conflict, and prevent those tables from being locked by the transaction?

  • Compare associations between domain objects in Grails

    - by user303979
    I am not sure if I am going about this the best way, but I will try to explain what I am trying to do. I have the following domain classes class User { static hasMany = [goals: Goal] } So each User has a list of Goal objects. I want to be able to take an instance of User and return 5 Users with the highest number of matching Goal objects (with the instance) in their goals list. Can someone kindly explain how I might go about doing this?

  • NSMutableArray with only a particular type of objects

    - by Leo
    Hello, is it possible to specify that a NSMutableArray can only contain a certain type of objects. For example, if I want to store only this kind of objects : @interface MyObject : NSObject { UInt8 value; } In order to be able to use the instance variable like this : - (void)myMethod:(NSMutableArray *)myArray{ for (id myObject in myArray){ [self otherMethod:myObject.value]; } } because I'm getting this error : request for member 'value' in something not a structure or union Thank you for your help

  • Debugging MEF running in ASP.NET

    - by Jeffrey Lott
    I'm trying to do a proof of concept app for my work using ASP.NET WebForms and the Managed Extensibility Framework. I've got things up and running(ish), but I can't seem to figure out how to attach the instance of Visual Studio that has the MEF code in it to the instance of Visual Studio that is running the Web App. How can I attach my MEF code to the running process so that it hits my breakpoints?

  • ProgrammingError: (1146, "Table 'test_<DB>.<TABLE>' doesn't exist") when running unit test for Djang

    - by abigblackman
    I'm running a unit test using the Django framework and get this error. Running the actual code does not have this problem, running the unit tests creates a test database on the fly so I suspect the issue lies there. The code that throws the error looks like this member = Member.objects.get(email=email_address) and the model looks like class Member(models.Model): member_id = models.IntegerField(primary_key=True) created_on = models.DateTimeField(editable=False, default=datetime.datetime.utcnow()) flags = models.IntegerField(default=0) email = models.CharField(max_length=150, blank=True) phone = models.CharField(max_length=150, blank=True) country_iso = models.CharField(max_length=6, blank=True) location_id = models.IntegerField(null=True, blank=True) facebook_uid = models.IntegerField(null=True, blank=True) utc_offset = models.IntegerField(null=True, blank=True) tokens = models.CharField(max_length=3000, blank=True) class Meta: db_table = u'member' there's nothing too odd there i can see. the user running the tests has the same permissions to the database server as the user that runs the website where else can I look to see what's going wrong, why is this table not being created?

  • Django freezes when adding objects through the admin

    - by Quartz
    I have a Django 1.1 website running via Apache/mod_wsgi with a PostgreSQL 8.3.1 database. Recently, when I added objects through the admin interface, the connection froze up and I lost several worker processes, so I had to restart Apache. Upon trying to replicate this, I found that it only happens through the admin: if I go into the Django shell and issue the same insert, it works fine. Also, performing an UPDATE operation works without issues, so just INSERTs. I've rebuilt indexes on PostgreSQL and run a full VACUUM. Error logs don't show anything, and I can't figure out for the life of me what's wrong. Anyone have any ideas?
