• SQL Server Full-Text Search: Hung processes with MSSEARCH wait type

  - by CheeseInPosition

  We have a SQL Server 2005 SP2 machine running a large number of databases, all of which contain full-text catalogs. Whenever we try to drop one of these databases or rebuild a full-text index, the drop or rebuild process hangs indefinitely with a MSSEARCH wait type. The process can’t be killed, and a server reboot is required to get things running again. Based on a Microsoft forums post[1], it appears that the problem might be an improperly removed full-text catalog. Can anyone recommend a way to determine which catalog is causing the problem, without having to remove all of them? [1] [http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2681739&SiteID=1] “Yes we did have full text catalogues in the database, but since I had disabled full text search for the database, and disabled msftesql, I didn't suspect them. I got however an article from Microsoft support, showing me how I could test for catalogues not properly removed. So I discovered that there still existed an old catalogue, which I ,after and only after re-enabling full text search, were able to delete, since then my backup has worked”

• Way to Remove Invite Limit on FBML Multi-Friend Selector

  - by David

  Hi there, I tried to look through various resources before posting here, but was having a surprisingly difficult time finding an answer to my question. Sorry in advance if I overlooked it. I'm currently trying to add the FBML Multi-Friend Selector to my Facebook page. It has a limit on the number of friends you can invite at a time ("Add up to 20 of your friends by clicking on their pictures below"). From what I've looked through it sounds like 20 is the max number of friends a user can invite, but then looking at Mint's page, they have a 22 max invite (http://www.facebook.com/mint?ref=ts) I thought it might be based on number of page fans, as Mint has 56,000, but that doesn't seem to be the case as this page only has 256 fans and have a max of 26 friend invites (http://www.facebook.com/tivix?v=app_106437999388442). Therefore, I don't really understand how this system works. Is there a way for me to increase to 26? Unlimited? Thanks for your help!

• SQL Where question

  - by needshelp

  Hi all, I have a question about case statements and nulls in a where clause. I want to do the following: Declare @someVar int = null select column1 from TestTable t where t = case when @someVar is not null then @someVar else t end Here is the problem: Let's say @someVar is null. Let's also say that column1 from TestTable t has NULL column values. Then, my condition t = t in the case statement will always evaluate to false. I basically just want to be able to conditionally filter the column based on the value of @someVar if it's provided. Any help?

• Tracking Google Analytics events with server side request automation

  - by Esko

  I'm currently in the process of programming an utility which generates GA tracking pixel (utm.gif) URL:s based on given parameters. For those of you who are wondering why I'm doing this on the server side, I need to do this server side since the context which I'm going to start tracking simply doesn't support JavaScript and as such ga.js is completely useless to me. I have managed to get it working otherwise quite nicely but I've hit a snag: I can't track events or custom variables because I have no idea how exactly the utme parameter's value should be structured to form a valid event or var type hit. GA's own documentation on this parameter isn't exactly that great, either. I've tried everything from Googling without finding anything (which I find ironic) to reverse engineering ga.js, unfortunately it's minified and quite unreadable because of that. The "mobile" version of GA didn't help either since officially GA mobile doesn't support events nor vars. To summarize, what is the format of the utme parameter for page hit types event and custom variable?

• Sorting in SSRS Reports overriding Group sorting

  - by Siva

  I am new to SSRS (2005) and am creating my first report. I need to create a group-based running value but is sorted or some other field. For example, from the data below |Employee| Day |Hours|Salary| |E1 | 1.1 | 5 | 5 | |E2 | 1.2 | 6 | 6 | |E3 | 1.3 | 7 | 7 | |E2 | 2.1 | 6 | 12 | |E1 | 2.2 | 5 | 10 | |E3 | 2.3 | 7 | 14 | |E3 | 3.1 | 7 | 21 | |E2 | 3.2 | 6 | 18 | I am calculating the salary to be a running value on hours grouped by employee, which works fine. The problem is I want the report to be sorted on the Day column. If I use the Day as a sorting criteria in the employee group, the report is grouped on the employee, but within the group, the data is sorted on the Day column. Is there a way to build the report and then finally sort the report on the day column ? Please let me know in case I am unclear. Thanks a lot! Siva.

• IText Lines Per Page?

  - by exit174

  I have used IText(Sharp) to make PDFs from raster images but have never used IText to build text based PDF's. In this new scenario, I have N words of ASCII text that I need to add as text pages to a new PDF. Each page should be 8.5 x 11, .5 margins, using some monospaced font. Is IText(Sharp) smart enough to automatically apply line and page breaks where necessary or do I need to do this manually? Are their any good IText tutorials for this scenario? thanks! scottm

• How to render Asian characters in a PDF using xhtmlrenderer

  - by Mark Derricutt

  I was wondering what steps were needed to render Asian characters using the java based xhtmlrenderer (flying saucer) library? I am wanting to render the following: <html> <body>????????</body> </html> Without any font settings being added to the HTML this renders fine in normal browsers, but I can't find anyway to render this to PDF using the iTextRenderer portion of xhtmlrenderer. After following various threads on the mailing list, I see lots of posts talking about adding .TTF files from the c:\windows\fonts directory, and I have modified the examples to run on linux ( https://gist.github.com/643173745182c9becc57 ), which shows me various fonts being displayed, but I don't see any Asian glyffs. Does anyone have any decent pointers, or clean solutions to this problem? Or am I looking at the wrong problem with a really simple solution elsewhere?

• Web Page Rendering Capture

  - by Chaitanya

  I start with describing the problem itself. Rather than a problem I'm looking for a better solution. I have a asp.net page which has a bunch of images and a link underneath it, Each image is infact the latest rendering of the link underneath it. I scheduled a bat script which runs every hour to fetch the images through IECapt a web page rendering capture utility. One thing am annoyed about this utility is it takes a lot of time for the 20 images I have and for few because of the flash content it misses to take the actual screenshot of the website. Now I like to know can this rendering be done by traditional programming am not interested in using any utilities. I'm interested in trying this. The solution need not be necessarily a C# based am ready to try in any other language. Because it gives me a chance to learn. Thank you.

• Finding first alphabetic character in a DB2 database field

  - by Paul Alan Taylor

  I'm doing a bit of work which requires me to truncate DB2 character-based fields. Essentially, I need to discard all text which is found at or after the first alphabetic character. e.g. 102048994BLAHBLAHBLAH becomes:- 102048994 In SQL Server, this would be a doddle - PATINDEX would swoop in and save the day. Much celebration would ensue. My problem is that I need to do this in DB2. Worse, the result needs to be used in a join query, also in DB2. I can't find an easy way to do this. Is there a PATINDEX equivalent in DB2? Is there another way to solve this problem? If need be, I'll hardcode 26 chained LOCATE functions to get my result, but if there is a better way, I am all ears.

I see somewhere is that, i have to detect two touch events in TouchBegan and then Adjust the Sprite Scale size to up or down based on the distance of two fingers touch event values. Could someone please tell me, How do i detect two fingers touch values in TouchBegan? How to allow to touch and Zoom-in/out of Sprite image by user? Please give me samples.

• Crash when trying to get NSManagedObject from NSFetchedResultsController after 25 objects?

  - by Jeremy

  Hey everyone, I'm relatively new to Core Data on iOS, but I think I've been getting better with it. I've been experiencing a bizarre crash, however, in one of my applications and have not been able to figure it out. I have approximately 40 objects in Core Data, presented in a UITableView. When tapping on a cell, a UIActionSheet appears, presenting the user with a UIActionSheet with options related to the cell that was selected. So that I can reference the selected object, I declare an NSIndexPath in my header called "lastSelection" and do the following when the UIActionSheet is presented: // Each cell has a tag based on its row number (i.e. first row has tag 0) lastSelection = [NSIndexPath indexPathForRow:[sender tag] inSection:0]; NSManagedObject *managedObject = [self.fetchedResultsController objectAtIndexPath:lastSelection]; BOOL onDuty = [[managedObject valueForKey:@"onDuty"] boolValue]; UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"Status" delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil]; if(onDuty) { [actionSheet addButtonWithTitle:@"Off Duty"]; } else { [actionSheet addButtonWithTitle:@"On Duty"]; } actionSheet.actionSheetStyle = UIActionSheetStyleBlackOpaque; // Override the typical UIActionSheet behavior by presenting it overlapping the sender's frame. This makes it more clear which cell is selected. CGRect senderFrame = [sender frame]; CGPoint point = CGPointMake(senderFrame.origin.x + (senderFrame.size.width / 2), senderFrame.origin.y + (senderFrame.size.height / 2)); CGRect popoverRect = CGRectMake(point.x, point.y, 1, 1); [actionSheet showFromRect:popoverRect inView:[sender superview] animated:NO]; [actionSheet release]; When the UIActionSheet is dismissed with a button, the following code is called: - (void)actionSheet:(UIActionSheet *)actionSheet willDismissWithButtonIndex:(NSInteger)buttonIndex { // Set status based on UIActionSheet button pressed if(buttonIndex == -1) { return; } NSManagedObject *managedObject = [self.fetchedResultsController objectAtIndexPath:lastSelection]; if([actionSheet.title isEqualToString:@"Status"]) { if([[actionSheet buttonTitleAtIndex:buttonIndex] isEqualToString:@"On Duty"]) { [managedObject setValue:[NSNumber numberWithBool:YES] forKey:@"onDuty"]; [managedObject setValue:@"onDuty" forKey:@"status"]; } else { [managedObject setValue:[NSNumber numberWithBool:NO] forKey:@"onDuty"]; [managedObject setValue:@"offDuty" forKey:@"status"]; } } NSError *error; [self.managedObjectContext save:&error]; [tableView reloadData]; } This might not be the most efficient code (sorry, I'm new!), but it does work. That is, for the first 25 items in the list. Selecting the 26th item or beyond, the UIActionSheet will appear, but if it is dismissed with a button, I get a variety of errors, including any one of the following: [__NSCFArray section]: unrecognized selector sent to instance 0x4c6bf90 Program received signal: “EXC_BAD_ACCESS” [_NSObjectID_48_0 section]: unrecognized selector sent to instance 0x4c54710 [__NSArrayM section]: unrecognized selector sent to instance 0x4c619a0 [NSComparisonPredicate section]: unrecognized selector sent to instance 0x6088790 [NSKeyPathExpression section]: unrecognized selector sent to instance 0x4c18950 If I comment out NSManagedObject *managedObject = [self.fetchedResultsController objectAtIndexPath:lastSelection]; it doesn't crash anymore, so I believe it has something do do with that. Can anyone offer any insight? Please let me know if I need to include any other information. Thanks! EDIT: Interestingly, my fetchedResultsController code returns a different object every time. Is this expected, or could this be a cause of my issue? The code looks like this: - (NSFetchedResultsController *)fetchedResultsController { /* Set up the fetched results controller. */ // Create the fetch request for the entity. NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; // Edit the entity name as appropriate. NSEntityDescription *entity = [NSEntityDescription entityForName:@"Employee" inManagedObjectContext:self.managedObjectContext]; [fetchRequest setEntity:entity]; // Set the batch size to a suitable number. [fetchRequest setFetchBatchSize:80]; // Edit the sort key as appropriate. NSString *sortKey; BOOL ascending; if(sortControl.selectedSegmentIndex == 0) { sortKey = @"startTime"; ascending = YES; } else if(sortControl.selectedSegmentIndex == 1) { sortKey = @"name"; ascending = YES; } else { sortKey = @"onDuty"; ascending = NO; } NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:sortKey ascending:ascending]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [fetchRequest setSortDescriptors:sortDescriptors]; // Edit the section name key path and cache name if appropriate. NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:self.managedObjectContext sectionNameKeyPath:nil cacheName:@"Root"]; aFetchedResultsController.delegate = self; self.fetchedResultsController = aFetchedResultsController; [aFetchedResultsController release]; [fetchRequest release]; [sortDescriptor release]; [sortDescriptors release]; NSError *error = nil; if (![fetchedResultsController_ performFetch:&error]) { /* Replace this implementation with code to handle the error appropriately. abort() causes the application to generate a crash log and terminate. You should not use this function in a shipping application, although it may be useful during development. If it is not possible to recover from the error, display an alert panel that instructs the user to quit the application by pressing the Home button. */ //NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } return fetchedResultsController_; } This happens when I set a breakpoint: (gdb) po [self fetchedResultsController] <NSFetchedResultsController: 0x61567c0> (gdb) po [self fetchedResultsController] <NSFetchedResultsController: 0x4c83630>

• Detect backspace in UITextField

  - by marcc

  Is there any way to detect when the backspace/delete key is pressed in the iPhone keyboard on a UITextField that is empty? I want to know when backspace is pressed only if the UITextField is empty. Based on the suggestion from @Alex Reynolds in a comment, I've added the following code while creating my text field: [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleTextFieldChanged:) name:UITextFieldTextDidChangeNotification object:searchTextField]; This notification is received (handleTextFieldChanged function is called), but still not when I press the backspace key in an empty field. Any ideas? There seems to be some confusion around this question. I want to receive a notification when the backspace key is pressed. That's it. But the solution must also work when the UITextField is already empty.

• How to log subsonic3 sql

  - by bastos.sergio

  Hi, I'm starting to develop a new asp.net application based on subsonic3 (for queries) and log4net (for logs) and would like to know how to interface subsonic3 with log4net so that log4net logs the underlying sql used by subsonic. This is what I have so far: public static IEnumerable<arma_ocorrencium> ListArmasOcorrencia() { if (logger.IsInfoEnabled) { logger.Info("ListarArmasOcorrencia: start"); } var db = new BdvdDB(); var select = from p in db.arma_ocorrencia select p; var results = select.ToList<arma_ocorrencium>(); //Execute the query here if (logger.IsInfoEnabled) { // log sql here } if (logger.IsInfoEnabled) { logger.Info("ListarArmasOcorrencia: end"); } return results; }

• Where is the displaytag of scheduled reporting?

  - by Nathan Feger

  So I have been making some reports and using displaytag to output these reports in html, csv, excel, pdf, etc. They are paginated, and take a simple object graph... and output excellent results everytime, with very little code. However, I need to use displaytag or its equivalent outside of a jsp. So that a user can schedule a report to run, and that report is stored in a db, or emailed for later viewing. I have looked at jasper-based reporting solutions, but making a jasper jrxml file is just a nightmare. I know there are gui tools to help, but I'm content with the simple output of displaytable, so I'm happy to give up that control for ease of implementation. Really, if I could take the display:table config out of the jsp I would, so please keep that in mind when proposing a solution. btw, java solutions would be my cup of tea.

• D3.js binding an object to data and appending for each key

  - by frshca

  I'm a D3.js newbie and I'm learning how to play around with data. Let's say I have an object with names as keys, and each key has an array of numbers like this: var userdata = { 'John' : [0, 1, 3, 9, 8, 7], 'Harry': [0, 10, 7, 1, 1, 11], 'Steve': [3, 1, 4, 4, 4, 17], 'Adam' : [4, 77, 2, 13, 11, 13] }; For each user, I would like to append an SVG object and then plot the line with the array of values for that user. So here is my assumption of how that would look based on tutorials, but I know it is incorrect. This is to show my limited knowledge and give better understanding of what I'm doing: First I should create the line var line = d3.svg.line().interpolate('basis'); Then I want to bind the data to my body and append an svg element for each key: d3.select('body') .selectAll('svg') .data(userdata) .enter() .append('svg') .append(line) .x(function(d, i) { return i; }) .y(function(d) { return d[i]; }); So am I close??

• The type or namespace name 'Mvc' does not exist in the namespace 'System.Web'

  - by Guy

  After converting a Hybrid ASP.NET MVC1 app to MVC2 I'm getting the following error when I try and run the application: The type or namespace name 'Mvc' does not exist in the namespace 'System.Web' (are you missing an assembly reference?) The allegeded culprit in the web.config file is System.Web.Mvc: <namespaces> <add namespace="System.Web.Mvc"/> <add namespace="System.Web.Mvc.Ajax"/> <add namespace="System.Web.Mvc.Html"/> So far my investigation seems to lead me to believe that version 2 of System.Web.Mvc is not installed or has not been picked up. I've tried creating a File New Project based on MVC 2 and that's picking up the new (v2) version of MVC. I've also converted some other projects (that were not hybrids) and they've converted without problem to MVC2. I've also uninstalled MVC1 to try and remove references to it from the GAC. However, none of this has worked. Any ideas?

• JavaScript: catching URI change

  I have a site where I'm using hash based parameters, eg. http://url.of.site/#param1=123 What I want When the user manually changes the URI to eg. http://url.of.site/#param1=789 When the user enters this URI, the event is caught by the JavaScript, and the appropriate functions are called. Basically, what I'm wondering about is; is there an event listener for this? Or would I have to periodically check the URI to see if it has been changed? I'm already using the current jQuery API, if that helps. _L

• FullText Search using multiple tables in SQL

  - by Caesar

  Hi there. I have 3 tables, tblBook(BookID, ISBN, Title, Summary) tblAuthor(AuthorID, FullName) tblBookAuthor(BookAuthorID, BookID, AuthorID) tblBookAuthor allows for a single book to have multiple authors and an author may have written any number of books. I am using full text search to search for ranking base on a word: SET @Word = 'FORMSOF(INFLECTIONAL, "' + @Word + '")' SELECT COALESCE(ISBNResults.[KEY], TitleResults.[KEY], SummaryResults.[KEY]) AS [KEY], ISNULL(ISBNResults.Rank, 0) * 3 + ISNULL(TitleResults.Rank, 0) * 2 + ISNULL(SummaryResults.Rank, 0) AS Rank FROM CONTAINSTABLE(tblBook, ISBN, @Word, LANGUAGE 'English') AS ISBNResults FULL OUTER JOIN CONTAINSTABLE(tblBook, Title, @Word, LANGUAGE 'English') AS TitleResults ON ISBNResults.[KEY] = TitleResults.[KEY] FULL OUTER JOIN CONTAINSTABLE(tblBook, Summary, @Word, LANGUAGE 'English') AS SummaryResults ON ISBNResults.[KEY] = SummaryResults.[KEY] The above code works fine for just searching tblBook table. But now I would like to search also the table tblAuthor based on key word searched. Can you help me with this?

• Using Nearest Neighbour Algorithm for image pattern recognition

  - by user293895

  So I want to be able to recognise patterns in images (such as a number 4), I have been reading about different algorithms and I would really like to use the Nearest Neighbour algorithm, it looks simple and I do understand it based on this tutorial: http://people.revoledu.com/kardi/tutorial/KNN/KNN_Numerical-example.html Problem is, although I understand how to use it to fill in missing data sets, I don't understand how I could use it as a pattern recognition tool to aim in Image Shape Recognition. Could someone please shed some light as to how this algorithm could work for pattern recognition? I have seen tutorials using OpenCV, however I don't really want to use this library as I have the ability to do the pre-processing myself, and it seems silly that I would implement this library just for what should be a simple nearest neighbour algorithm.

• iPhone:Tabbar item actions are not happening

  - by user187532

  Hello all, I created a window application, which has a tabbar controller with four tabbar items. Each tabbar items are linked with a tableview. I have also set Navigation bar for each tabbar items. I have appdelegate file, which calls the first tableview controller of which is set for first tabbar item. I am trying to retrieve and do an action whenever a tabbar item is clicked. For that, i tried to add "- (void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item" and "- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UITableViewController *)viewController" in my first tableview controller, but it is not at all responding whenever i click any tabbar items. My question is, if i create a window based application and added tabbar controller, tableview and navigation bar in .XIB file, is it not possible to access and do an action programatically whenever a tabbar item is clicked? (or) Am i doing anything wrong? Please help me to resolve this and share your ideas. Thanks.

• Silverlight 4 - authentiation / authorization against custom wcf service

  - by Calanus

  I have a wcf service in front of an AzMan store that passes roles and operations to clients using the following interface: [OperationContract] bool AuthenticateUser(string password, string appName); [OperationContract] string[] GetRoles(string storelocation, string appName); [OperationContract] string[] GetOperations(string storeLocation, string appName, string selectedRole); Clients connect to this service using windows authentication (but users must send their password through to reaffirm their identity). Ultimately the service delivers an array of operations that each client can perform based on their selected role. I've opened a new Silverlight Business Application and tried to understand how authentication/authorization works in this template, as well as scoured the web to find examples to how to hook my webservice to the login box already created in the template, but I am completely at a loss as how to do this! Can anyone offer any advice?

• How to detect non-graceful disconnect of Twisted on Linux?

  - by Victor Lin

  I wrote a server based on Twisted, and I encountered a problem, some of the clients are disconnected not gracefully. For example, the user pulls out the network cable. For a while, the client on Windows is disconnected (the connectionLost is called, and it is also written in Twisted). And on the Linux server side, my connectionLost of twisted is never triggered. Even it try to writes data to client, but the connection is lost. Why Twisted can't detect those non-graceful disconnection (even write data to client) on Linux? How to makes Twisted detect non-graceful disconnections? Because the feature Twisted can't detect non-graceful, I have lots of zombie user on my server. Thanks. Victor Lin.

• Formatting an indented list in CSS

  - by Colen

  Hi, Let's say I have a list, with an arbitrary number of indentation levels, like so: Item Item Item Item Item Item Item Item Item Item Item If I'm displaying this list in an HTML document, how can I use CSS to handle the indentation? There might be an arbitrary number of indentation levels (although in practice there isn't going to be more than 5 or so). I don't want to create an "indent1" class that indents 10 pixels, an "indent2" class that indents 20 pixels, etc - that's clumsy. Is it possible to create a general rule that will indent by a certain distance based on an attribute value, or the position of an element in the hierarchy?
