• Manually removing sql server 2008

  - by user193655

  I am not able to remove sql server 2008 from my machine. I installed it in the past as a part of the installation of an application, this installed the runtime of sql server 2008 SP0. But now I cannot uninstall. I tried to use the setup of SP0 and even of SP2 but it was not able to uninstall, by giving fatal errors when it does the preliminary checks. This means that the only option I have is format my machine? I cannot even intall a new instance, something is really corrupted. Is it a way to remove it manually?

• How do I set an array in one class with another array in another class

  - by Stef

  I've populated and array with data like this in one class... PowerClass.h NSMutableArray pickerArray; @property (nonatomic, retain) NSMutableArray pickerArray; - PowerClass.m @synthesize pickerArray; @implementation NSMutableArray *array = [[NSArray alloc] initWithObjects:@"stef", @"steve", @"baddamans", @"jonny", nil]; pickerArray = [NSMutableArray arrayWithArray:array]; And I'm trying to set the Array in another class WeekClass.h PowerClass *powerClass; NSMutableArray *pickerData; @property (nonatomic, retain) NSMutableArray pickerData; @property (nonatomic, retain) PowerClass *powerClass; WeekClass.m @implementation pickerData = [NSMutableArray arrayWithArray:powerClass.pickerArray]; I have no errors or warnings. It just crashes. The NSLog says that the powerClass.pickerArray is NULL. Please help point me in the right direction.

• Why are error pages ignored in RESTEasy web service running on Tomcat?

  - by Chandru

  I'm developing a REST-ful web service using RESTEasy deployed on Tomcat. I've configured an error page which takes the exception's message and generates an XML based on it when any exception occurs during the request. This works fine for any application generated exceptions. However, if client sends an invalid XML which cannot be unmarshalled correctly, an javax.xml.bind.UnmarshalException is thrown and Tomcat's default error page is used instead of mine. I have configured my error page to the error-code 500 in web.xml. Is using error pages the correct way to handle errors when using RESTEasy or is there an alternative way?

• ruby 1.9: invalid byte sequence in UTF-8

  - by Marc Seeger

  I'm writing a crawler in ruby (1.9) that consumes lots of HTML from a lot of random sites. When trying to extract links, I decided to just use .scan(/href="(.*?)"/i) instead of nokogiri/hpricot (major speedup). The problem is that I now receive a lot of "invalid byte sequence in UTF-8" errors. From what I understood, the net/http library doesn't have any encoding specific options and the stuff that comes in is basically not properly tagged. What would be the best way to actually work with that incoming data? I tried .encode with the replace and invalid options set, but no success so far...

• Can a program that controls IE detect if a HTTP 30x code is encountered?

  - by hillu

  I am trying to control an InternetExplorer.Application via the COM interface, using Perl, Win32::OLE, and information from MSDN. My goal is to get as good an idea as possible about what IE is doing. (Related to this question.) IE uses events to notify my program when it has finished various stages of processing a certain URL (NavigateComplete2, DownloadComplete DocumentComplete). It can also tell my program about various errors it encounters (NavigateError2). I consider that part of my problem solved well enough. I would also like to be able to reliably detect if IE is redirected by the server. Primarily, I'm concerned about HTTP 30x status codes. Is there a way to do this, either with COM automation or via another route?

• Problems with South/Django: not recognizing the Django App

  - by christmasgorilla

  I've got a Django project on my machine and when I try to use South to migrate the data schema, I get several odd errors. Example: $ python manage.py convert_to_south thisLocator /Library/Python/2.6/site-packages/registration/models.py:4: DeprecationWarning: the sha module is deprecated; use the hashlib module instead import sha /Users/cm/code/thisLocator/../thisLocator/batches/models.py:6: DeprecationWarning: the md5 module is deprecated; use hashlib instead import md5 There is no enabled application matching 'thisLocator'. I've followed the South documentation. Settings.py has it in the installed apps, I can run import south from the manage.py shell. Everyone else on my team is calling the app thisLocator. Am I doing something really stupid?

• Question about spring manning-in-action

  - by Gandalf StormCrow

  I saw people asking about best book for learning spring, and I came across manning.spring in action was recommended most of the time so I decided to give it a go. The thing is the author offers some pretty reasonable explanations, puzzle by puzzle it gets in your head, than you just need to code it and you're done, you get it(this is how I work don't know about the others). When it comes to the code its very disapointing, I went trought the Knight example like 2 or 3 times by now and I see its incorrect in the book, I mean its hard already for people eager to learn and why not a note somewhere in the book like pseudo-code or something. The knight example in the first chapter is missing two classes QuestFailedException and HolyGrail I mean other people must have noticed this, why is everyone recommending this book without saying at least it has some errors(like many others do), was anyone actually been able to compile and this first chapter example?

• Tiny MCE ImageManager Plugin, "cant create instance of plugin"

  - by Lofving

  We just bought MCImageManager and went right on to creating our own plugin. I followed http://wiki.moxiecode.com/index.php/MCI … ing_plugin from start to end but got stuck on the last step. After configuring the build.bat file (that comes along the package) it gives me no errors, i checked all paths and it should work but there just is no plugin.dll file anywhere to be found. (The bat file is also linked to the .net 1.4322, that should be changed by you at tinyMCE in my opinion) To circumvent that problem I started a new project and compiled the plugin.dll through Visual Studio. Then placed the dll in the c:..\project\plugins\plugin\bin\ folder (at the same place as the _TemplatePlugin.dll file but with the plugins name) All i get from running the application is "Could not create instance of plugin class: Moxiecode.Manager.Plugins.Plugin" What is it I'm missing? All the other plugins ain't giving this error and they follow the same structure as my custom plugin. Thanks in advance //Micael

• Joining Multiple Projects in one solution

  - by PCAddict

  I have started creating a game, and I added a second project, it's the standard XNA Windows game 3.1 project, and since the other project already had a Main to start the program and the 2nd is for game data, where as the first was for the drawing and graphical side of things (menu's etc) I thought I would remove the Main method, and now all I get are Errors saying there isn't a Valid main method, I tried to make it dependant on the other (since this data is loaded at run time and is such as quests/items etc) but it still wont let me run the solution at all. the code for the main method is still in the 1st project, and if I delete the 2nd project it runs fine, although no game data so I only get menus... Thank you in advance for any assistance.

• iPhone keyboard doesn't appear when entering a UITextField

  - by Norm

  This has to be some kind of newbie blunder that I just can’t see, and I’d be grateful for hints as to what to check or where to look. I've followed an iPhone tutorial that has a UITextField, making sure I connected the IBOutlet for the text field, and it seems to compile properly (no errors or warnings). But when I run it under the simulator, and click in the field, I don’t get the keyboard, so I can’t enter anything into the field. I’ve tried searching the site for similar questions, and all I’ve found is a few questions where the developer is trying to set up some complex UI with multiple controllers, and one that seemed to be the same issue, but the original poster simply said that he solved it by starting a new project and porting the code over. I’d like to find an actual solution, so I don’t have to try randomly rebuilding projects when this issue comes up again. Thanks!

• jaxb XmlAccessType: PROPERTY example

  - by Bjorn J

  I'm trying to use jaxb and want to use the 'XmlAccessType.PROPERTY' to let jaxb use getters/setters rather than variable directly, but get different errors depending on what I try, or the variable isn't set at all like I want. Any good link or pointer to a simple example? For example, the below makes the groupDefintion not to be set when parsing the xml document: @XmlAccessorType(javax.xml.bind.annotation.XmlAccessType.PROPERTY) public class E { private EGroup groupDefinition; public EGroup getGroupDefinition () { return groupDefinition; } @XmlAttribute public void setGroupDefinition (EGroup g) { groupDefinition = g; } }

• WebKit and npapi and mingw-w64

  - by rubenvb

  Hi, The problem is the following: On Windows x64, pointers are 64-bit, but type long is 32-bit. MSVC doesn't seem to care, and even omits warnings about pointer truncation on the default warning level. Since recently, there is a GCC that target x86_64-w64-mingw32, or better Windows x64 native. GCC produces errors when pointers are truncated (which is the logical thing to do...), and this is causing trouble in WebKit and more specifically, the Netscape Plugin API: First, there's the files (I can only post one hyperlink...): http://trac.webkit.org/browser/trunk/WebCore/ bridge/npapi.h -- defines uint32 as 32-bit int type (~line 145) plugins/win/PluginViewWin.cpp -- casts Windows window handles to 32-bit int, truncating them (~line 450) My proposed fix was to change the uint32 casts to uintptr_t, which makes GCC happy, but still puts a 64-bit value in a uint32 (=unsigned long). I have no clue how to solve this, because clearly WebKit is happy truncating pointers on Win64... How can I solve this the right way? Thanks!

• Unable to send email on production server with ASP.NET MVC

  - by Davide Vosti

  I have a simple ASP.NET MVC application with a contact page. In my development machine (local) I can send successfully emails (I specify host and credentials), but on the production server this doesn't work and I get this error: System.Net.Mail.SmtpFailedRecipientException: Mailbox unavailable. The server response was: Requested action not taken: mailbox unavailable or not local at System.Net.Mail.SmtpTransport.SendMail... The server is in my LAN (the mail server too). I tried with multiple accounts but I have errors every time. Credentials for the account are provided at runtime with smtp.Credentials = new NetworkCredential("username", "password"); Any idea? Thanks

• Strange error in ASP.NET

Is there any source of documentation on how each one is used?

• Virtual dedicated surver repetitive draining RAM, OOM constantly

• SQL Server - Schema/Code Analysis Rules - What would your rules include?

  - by Randy Minder

  We're using Visual Studio Database Edition (DBPro) to manage our schema. This is a great tool that, among the many things it can do, can analyse our schema and T-SQL code based on rules (much like what FxCop does with C# code), and flag certain things as warnings and errors. Some example rules might be that every table must have a primary key, no underscore's in column names, every stored procedure must have comments etc. The number of rules built into DBPro is fairly small, and a bit odd. Fortunately DBPro has an API that allows the developer to create their own. I'm curious as to the types of rules you and your DB team would create (both schema rules and T-SQL rules). Looking at some of your rules might help us decide what we should consider. Thanks - Randy

• Overriding classes/functions from a .dll.

  - by Jeff

  Say I have class A and class B. B inherits from class A, and implements a few virtual functions. The only problem is that B is defined in a .dll. Right now, I have a function that returns an instance of class A, but it retrieves that from a static function in the .dll that returns an instance of class B. My plan is to call the created object, and hopefully, have the functions in the .dll executed instead of the functions defined in class A. For some reason, I keep getting restricted memory access errors. Is there something I don't understand that will keep this plan from working?

• Changing SQL Server Database sorting

  - by plaisthos

  I have a request to change the collation of a SQL Server Database: ALTER DATABASE solarwind95 collate SQL_Latin1_General_CP1_CI_AS but I get this strange error: Meldung 5075, Ebene 16, Status 1, Zeile 1 Das 'Spalte'-Objekt 'CustomPollerAssignment.PollerID' ist von 'Datenbanksortierung' abhängig. Die Datenbanksortierung kann nicht geändert werden, wenn ein schemagebundenes Objekt von ihr abhängig ist. Entfernen Sie die Anhängigkeiten der Datenbanksortierung, und wiederholen Sie den Vorgang. Sorry for the german errror message. I do not know how to switch the language to english, but here is a translation: Translation: Message 5075, Layer 16, Status 1, Row 1 The 'column' object 'CustomPollerAssignment.PollerID' depends on 'Database sorting. The database sorting cannot be changed if a schema bound object depends on it. Remove the dependency of the database sortieren and retry. I got a ton more of the errors like that.

• How to create multiple tables with the same schema using SQLite jdbc

  - by Space_C0wb0y

  I want to split a large table horizontally, and I would like to make sure that all three of them have the same schema. Currently I am using this piece of code to create the tables: statement .executeUpdate("CREATE TABLE AnnotationsMolecularFunction (Id INTEGER PRIMARY KEY ASC AUTOINCREMENT, " + "ProteinId NOT NULL, " + "GOId NOT NULL, " + "UNIQUE (ProteinId, GOId)" + "FOREIGN KEY(ProteinId) REFERENCES Protein(Id))"); There is one such statement for each table. This is bad, because if I decide to change the schema later (which will most certainly happen), I will have to change it three times, which begs for errors, so I would like a way to make sure that the other tables have the same schema without explicitly writing it again. I can use: statement .executeUpdate("CREATE TABLE AnnotationsBiologicalProcess AS SELECT * FROM AnnotationsMolecularFunction"); to create the other tables with the same columns, but the constraints are not aplied. I could of course just generate the same query-string three times with different table-names in Java, but I would like to know if there is an SQL-way of achieving this.
