  • How to synchronize SQL Server 2008 database with SQL Server 2005 database?

    - by James McFarland
    I am using VS 2008 Team Suite and SQL Server 2008 in my development environment. I am deploying to a shared-host website with shared-host SQL Server 2005. I want to push changes from my development environment to my production host. I tried using Data | Schema Compare... and it reports to me that it does not support SQL Server 2008. What do people use for this (Besides Red-Gate tools - I use those at my day job, and they rock...this is a volunteer thing for my son's school)? I am looking for something very inexpensive if not free.

  • Acquiring Table Lock in Database - Interview Question

    - by harigm
    One of my interview Questions, if multiple users across the world are accessing the application, in which it uses a Table which has a Primary Key as Auto Increment Field. The Question how can you prevent the other user getting the Same Primary key when the other user is executing? My answer was I will obtain the Lock on the table and I will make the user to wait Until that user is released with the Primary key. But the Question How do you acquire the Table lock programmatically and implement this? If there are 1000 users coming every minute to the application, if you explicity hold the lock on the table, then the application will become slower? How do you manage this? Please suggest the possible answers for the above question

  • Database of common translated phrases for localization?

    - by richardtallent
    I'd like to localize my app into a few other languages, all of which I can barely order a drink in. Does anyone know of an online resource for translations of common software menu options, messages, etc. into other languages? Given the number of developers (both OSS and closed-source) that deal with localization, and the overlap of resource strings between, it seems like a pretty obvious fit for a wiki or open source package, but I can't seem to find anything like this. I could try to mine the Windows resource files or dig around in resource strings in robust OSS apps like Firefox, but I suspect I'm not the first person to think of this and surely there is a site that I'm just not finding yet. Update: since nothing exists like this that I could find, I started a feeble attempt at an open-source string library. It's just a boilerplate Google spreadsheet now, so if you want to contribute, please go here: http://www.xark.org/

  • What happens when auto_increment on integer column reaches the max_value in databases?

    - by Sanoj
    I am implementing a database application and I will use both JavaDB and MySQL as database. I have an ID column in my tables that has integer as type and I use the databases auto_increment-function for the value. But what happens when I get more than 2 (or 4) billion posts and integer is not enough? Is the integer overflowed and continues or is an exception thrown that I can handle? Yes, I could change to long as datatype, but how do I check when that is needed? And I think there is problem with getting the last_inserted_id()-functions if I use long as datatype for the ID-column.

  • Help to choose NoSQL database for project

    - by potapuff
    There is a table: doc_id(integer)-value(integer) Approximate 100k doc_id and 27?? rows. Majority query on this table - searching documents similar to current document: select 10 documents with maximum of (count common to current document value)/(count ov values in document). Nowadays we use PostgreSQL. Table weight (with index) ~1,5 GB. Average query time ~0.5s. Should I transfer all this to NoSQL base, if so, what?

  • Text encoding problem between NSImage, NSData, and NSXMLDocument

    - by andyvn22
    I'm attempting to take an NSImage and convert it to a string which I can write in an XML document. My current attempt looks something like this: [xmlDocument setCharacterEncoding: @"US-ASCII"]; NSData* data = [image TIFFRepresentation]; NSString* string = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding]; //Put string inside of NSXMLElement, write out NSXMLDocument. Reading back in looks something like this: NSXMLDocument* newXMLDocument = [[NSXMLDocument alloc] initWithData:data options:0 error:outError]; //Here's where it fails. I get: //Error Domain=NSXMLParserErrorDomain Code=9 UserInfo=0x100195310 "Line 7: Char 0x0 out of allowed range" I assume I'm missing something basic. What's up with this encoding issue?

  • Regular expression to extract text between either square or curly brackets

    - by ObiWanKenobi
    Related to my previous question, I have a string on the following format: this {is} a [sample] string with [some] {special} words. [another one] What is the regular expression to extract the words within either square or curly brackets, ie. {is} [sample] [some] {special} [another one] Note: In my use case, brackets cannot be nested. I would also like to keep the enclosing characters, so that I can tell the difference between them when processing the results.

  • How should I manage data in an 2D vector based animation program?

    - by shadow
    I've been trying to design a program that makes 2D animations and then uses the ffmpeg library to create the video for possible use in tv and movies. The problem is when I think about how to manage the data in the application I can only think of two ways, I don't think either of them will work out very well. One is to use an SQlite database, but it seems like it will be difficult to save, especially if an artist puts 1000 things on screen. The other is to use something like linked lists, which would duplicate many features of the database and get complicated when dealing with things like points on a bezier curve and jumping to a frame and collecting all the objects that need to be drawn on that frame. Should I use one of these solutions, or is there something else that would be better? Currently planning to use C# for code.

  • Cut off text before read more

    - by koko
    I have texts that most of the time fit in a div, but sometimes it doesn't fit. There is no way to determine how many characters/words/paragraphs fit in the div, so I can't cut it off that way. The div had a fixed height and width, so can we do something with that? Or do you have any suggestion how to get everything in the div, the correct way?

  • CSS placement of text

    - by Josh
    Anyone know how I can get "Posted by AUTHOR on April 3rd, 2010 | 0 Comments" underneath the headline of the news links WITHOUT it being apart of the A CLASS? I want it to look, read, and function like: [IMAGE] HEADLINE Posted by AUTHOR on April 3rd, 2010 | 0 Comments All of that in the initial looking field, then the user can click and it expands further. I can obviously get it to work if I put it in the A CLASS tag, but that's the problem. I can't have it there.

  • Database hosting options for a PosgreSQL project

    - by AJ
    PostgreSQL has announced an Android app [contest] (http://wiki.postgresql.org/wiki/AndroidAppContest). I wanted to try out something but the only hosting I have does not provide PostgreSQL. Do I have any economical (read cheap :D ) options? Is there a free hosting that anyone knows of? Thanks in advance. --AJ

  • idomatic batch processing of text in emacs?

    - by Stephen
    In python, you might do something like fout = open('out','w') fin = open('in') for line in fin: fout.write(process(line)+"\n") fin.close() fout.close() (I think it would be similar in many other languages as well). In emacs lisp, would you do something like (find-file 'out') (setq fout (current-buffer) (find-file 'in') (setq fin (current-buffer) (while moreLines (setq begin (point)) (move-end-of-line 1) (setq line (buffer-substring-no-properties begin (point)) ;; maybe (print (process line) fout) ;; or (save-excursion (set-buffer fout) (insert (process line))) (setq moreLines (= 0 (forward-line 1)))) (kill-buffer fin) (kill-buffer fout) which I got inspiration (and code) from here. Or should I try something entirely different? And how to remove the "" from the print statement? Thanks!

  • Is there an online user agent database?

    - by Gary Richardson
    How do you parse your user agent strings? I'm looking to get: Browser Browser Version OS OS Version from a user agent string. My app is written in perl and was previously using HTTP::BrowserDetect. It's a bit dated and is no longer maintained. I'm in no way tied to using perl for the actual lookup. I've come to the conclusion that automagic parsing is a lost cause. I was thinking of writing a crud type app to show me a list of unclassified UA's and manually keep them up to date. Does such an resource already exist that I can tap into? It would be awesome if I could make an HTTP call to look up the user agent info. Thanks!

  • Schemas and tables versus user-ids in a single table using PostgreSQL

    - by gvkv
    I'm developing a web app and I've come to a fork in the road with respect to database structure and I don't know which direction to take. I have a database with user information that I can structure one of two ways. The first is to create a schema and a set of tables for each user (duplicating the structure for each user) and the second is to create a single set of tables and query information based on user-id. Suppose 100000 users. Here are my questions: Considering security, performance, scalability and administration where does each choice lie? Would the answers change for 1000000 or 10000? Is there a set of best practices that lead to one choice or the other? It seems to me that multiple schemas are more secure since it's trivial to restrict user privileges but what about performance and scalability? Administration seems like a wash since dumping (and restoring) lots of schemas isn't any more difficult than dumping a few.
