• How to get the right order for creation of stored procedure, user-defined functions and triggers

  - by PeeWee2201

  I read that object dependencies have been improved in SQL server 2008. I have a rather complex database schema containing stored procedure, user-defined functions, triggers. Can anybody give me a query that would return the right order of creation of those items based on their dependencies ? I read here that there are tools that can do the job, but I am looking for something scriptable. Also, they often give the dependencies of one object and I would like a database-wide solution. Thank you.

• Android SQLiteConstraintException: error code 19: constraint failed

  - by Tom D

  I've seen other questions about this exception, but all of them seem to be resolved with the solution that a row with the primary key specified already exists. This doesn't seem to be the case for me. I have tried replacing all single quotes in my strings with double quotes, but the same problem occurs. I'm trying to insert a row into the Settings table of the SQLite database I've created by doing the following: db.execSQL("DROP TABLE IF EXISTS "+Settings.SETTINGS_TABLE_NAME + ";"); db.execSQL(CREATE_MEDIA_TABLE); db.execSQL(CREATE_SETTINGS_TABLE); Cursor c = getAllSettings(); //If there isn't already a settings row, create a row full of defaults if(c.getCount()==0){ ContentValues cv = new ContentValues(); cv.put(Settings.SETTING_UNIQUE_ID, "'"+Settings.uniqueID+"'"); cv.put(Settings.SETTING_DEVICE_ID, Settings.SETTING_DEVICE_ID_DEFAULT); cv.put(Settings.SETTING_CONNECTION_PREFERENCE, Settings.SETTING_CONNECTION_PREFERENCE_DEFAULT); cv.put(Settings.SETTING_AD_HOC_ENABLED, Settings.SETTING_AD_HOC_ENABLED_DEFAULT); cv.put(Settings.SETTING_SERVER_ADDRESS, Settings.SETTING_SERVER_ADDRESS_DEFAULT); cv.put(Settings.SETTING_RECORDING_MODE, Settings.SETTING_RECORDING_MODE_DEFAULT); cv.put(Settings.SETTING_PREVIEW_ENABLED, Settings.SETTING_PREVIEW_ENABLED_DEFAULT); cv.put(Settings.SETTING_PICTURE_RESOLUTION_X, Settings.SETTING_PICTURE_RESOLUTION_X_DEFAULT); cv.put(Settings.SETTING_PICTURE_RESOLUTION_Y, Settings.SETTING_PICTURE_RESOLUTION_Y_DEFAULT); cv.put(Settings.SETTING_VIDEO_RESOLUTION_X, Settings.SETTING_VIDEO_RESOLUTION_X_DEFAULT); cv.put(Settings.SETTING_VIDEO_RESOLUTION_Y, Settings.SETTING_VIDEO_RESOLUTION_Y_DEFAULT); cv.put(Settings.SETTING_VIDEO_FPS, Settings.SETTING_VIDEO_FPS_DEFAULT); cv.put(Settings.SETTING_AUDIO_BITRATE_KBPS, Settings.SETTING_AUDIO_BITRATE_KBPS_DEFAULT); cv.put(Settings.SETTING_STORE_TO_SD, Settings.SETTING_STORE_TO_SD_DEFAULT); cv.put(Settings.SETTING_STORAGE_LIMIT_MB, Settings.SETTING_STORAGE_LIMIT_MB_DEFAULT); this.db.insert(Settings.SETTINGS_TABLE_NAME, null, cv); } The CREATE_SETTINGS_TABLE string is defined as the following: private static String CREATE_SETTINGS_TABLE = "CREATE TABLE IF NOT EXISTS " + Settings.SETTINGS_TABLE_NAME + "(" + Settings.SETTING_UNIQUE_ID + " TEXT NOT NULL PRIMARY KEY, " + Settings.SETTING_DEVICE_ID + " TEXT NOT NULL , " + Settings.SETTING_CONNECTION_PREFERENCE + " TEXT NOT NULL CHECK("+Settings.SETTING_CONNECTION_PREFERENCE+" IN("+Settings.SETTING_CONNECTION_PREFERENCE_ALLOWED+")), " + Settings.SETTING_AD_HOC_ENABLED + " TEXT NOT NULL CHECK("+Settings.SETTING_AD_HOC_ENABLED+" IN("+Settings.SETTING_AD_HOC_ENABLED_ALLOWED+")), " + Settings.SETTING_SERVER_ADDRESS + " TEXT NOT NULL, " + Settings.SETTING_RECORDING_MODE + " TEXT NOT NULL CHECK("+Settings.SETTING_RECORDING_MODE+" IN("+Settings.SETTING_RECORDING_MODE_ALLOWED+")), " + Settings.SETTING_PREVIEW_ENABLED + " TEXT NOT NULL CHECK("+Settings.SETTING_PREVIEW_ENABLED+" IN("+Settings.SETTING_PREVIEW_ENABLED_ALLOWED+")), " + Settings.SETTING_PICTURE_RESOLUTION_X + " TEXT NOT NULL, " + Settings.SETTING_PICTURE_RESOLUTION_Y + " TEXT NOT NULL, " + Settings.SETTING_VIDEO_RESOLUTION_X + " TEXT NOT NULL, " + Settings.SETTING_VIDEO_RESOLUTION_Y + " TEXT NOT NULL, " + Settings.SETTING_VIDEO_FPS + " TEXT NOT NULL, " + Settings.SETTING_AUDIO_BITRATE_KBPS + " TEXT NOT NULL, " + Settings.SETTING_STORE_TO_SD + " TEXT NOT NULL CHECK("+Settings.SETTING_STORE_TO_SD+" IN("+Settings.SETTING_STORE_TO_SD_ALLOWED+")), " + Settings.SETTING_STORAGE_LIMIT_MB + " TEXT NOT NULL )"; However, when I execute my insert, I always get: 03-19 19:37:36.974: ERROR/Database(386): Error inserting server_address='0.0.0.0' storage_limit='-1' connection='none' preview_enabled='0' sd_enabled='1' video_fps='15' audio_bitrate='96' device_id='-1' recording_mode='none' picture_resolution_x='-1' picture_resolution_y='-1' unique_id='000000000000000' adhoc_enable='0' video_resolution_x='320' video_resolution_y='240' 03-19 19:45:34.284: ERROR/Database(446): android.database.sqlite.SQLiteConstraintException: error code 19: constraint failed It seems as if all the columns in my insert are not null.

• Timeout with GAE Java

  - by user242153

  Hi, I am having some issues with an app I have deployed on GAE. Specifically, I am intermittently running into the DeadlineExceededException where the server is not responding within the 30 seconds required. What is odd is that the code is not overly complex, it should run in milliseconds. My guess is that the delay is in dealing with the persistence manager and accessing the datastore. 2 questions: 1) What is the best way to track where all of the CPU time on the server is being used up? Log files do not seem helpful and to make things more complicated the code runs very fast when I am running it locally 2) Any tips / best practices in dealing with the 30 second exception? What are the biggest drivers of this? Datastore? HTTP requests / responses? Thanks

• 2d parabolic projectile

  - by ndg

  I'm looking to create a basic Javascript implementation of a projectile that follows a parabolic arc (or something close to one) to arrive at a specific point. I'm not particularly well versed when it comes to complex mathematics and have spent days reading material on the problem. Unfortunately, seeing mathematical solutions is fairly useless to me. I'm ideally looking for pseudo code (or even existing example code) to try to get my head around it. Everything I find seems to only offer partial solutions to the problem. In practical terms, I'm looking to simulate the flight of an arrow from one location (the location of the bow) to another. It strikes me there are two distinct problems here: determining the position of interception between the projectile and a (moving) target, and then calculating the trajectory of the projectile. Any help would be greatly appreciated.

• empty() not a valid callback?

  - by user151841

  I'm trying to use empty() in array mapping in php. I'm getting errors that it's not a valid callback. $ cat test.php <? $arrays = array( 'arrEmpty' => array( '','','' ), ); foreach ( $arrays as $key => $array ) { echo $key . "\n"; echo array_reduce( $array, "empty" ); var_dump( array_map("empty", $array) ); echo "\n\n"; } $ php test.php arrEmpty Warning: array_reduce(): The second argument, 'empty', should be a valid callback in /var/www/authentication_class/test.php on line 12 Warning: array_map(): The first argument, 'empty', should be either NULL or a valid callback in /var/www/authentication_class/test.php on line 13 NULL Shouldn't this work? Long story: I'm trying to be (too?) clever and checking that all array values are not empty strings.

• How can I transition from a front-end career to back-end career?

  - by jexx2345

  Hello, In 2004, I received my B.S. in Computer Science using mostly Java for programming. Since then, I have been hired for purely front-end positions in large companies through recruiters, doing primarily HTML/CSS, Javascript/jQuery, and OOP Actionscript 3. While I definitely have respect for the front-end, and have learned much, I feel very unfulfilled and would love to move into back-end for the more complex programming I was doing in school. My target platform of choice is ASP.Net 3.5 (C#). With a resume that has absolutely no .Net or back-end experience, how can I transition into a junior back-end job? I am currently freelancing a .Net e-commerce site, and plan to build a portfolio showcasing some apps (e-commerce mvc, blog, etc), while learning the technology. Is having a Bachelors in CS enough or should I look into getting .Net certified? Is showing course-work still relevant to an employer even though it was from 6 years ago? Thank you

• Extract multiple values from one column in MySql

  - by Neil

  I've noticed that MySql has an extensive search capacity, allowing both wildcards and regular expressions. However, I'm in somewhat in a bind since I'm trying to extract multiple values from a single string in my select query. For example, if I had the text "<span>Test</span> this <span>query</span>", perhaps using regular expressions I could find and extract values "Test" or "query", but in my case, I have potentially n such strings to extract. And since I can't define n columns in my select statement, that means I'm stuck. Is there anyway I could have a list of values (ideally separated by commas) of any text contained with span tags? In other words, if I ran this query, I would get "Test,query" as the value of spanlist: select <insert logic here> as spanlist from HtmlPages ...

• Replace a word in an XML file through StreamReader in XNA?

  - by kcoppock

  Okay, so this is sort of a hack...but it may have to be. I'm writing an app in XNA, which from my research into this problem apparently doesn't support XML version 1.1. I'm reading in the contents of an ePub document, and one of the newer books contains its content directory as a version 1.1 XML document. This causes my program to crash. However, the structure is the same as the rest, the only thing that should be keeping it from working is the hard-coded "1.0" in the XmlDocument class. Is it possible that I could read in the file from the stream, see if it contains: <?xml version="1.1" encoding="UTF-8" standalone="no"?> and simply replace it with "1.0"? Then I could pull it in as an XmlDocument. I'm not doing any writing to the file, or any complex structural reading, just looking for a few specific nodes, and pulling in the values, so I don't know what the ramifications of this would be.

• Possible to InvalidateVisual() on a given region instead of entire WPF control?

  - by Scott Bilas

  I have a complex WPF control that draws a lot of primitives in its OnRender (it's sort of like a map). When a small portion of it changes, I'd only like to re-issue render commands for the affected elements, instead of running the entire OnRender over. While I'm fine with my OnRender function's performance on a resize or whatever, it's not fast enough for mouse hover-based highlighting of primitives. Currently the only way I know how to force a screen update is to call InvalidateVisual(). No way to send in a dirty rect region to invalidate. Is the lowest granularity of WPF screen composition the UI element? Will I need to do my renders of primitives into an intermediate target and then have that use InvalidateVisual() to update to the screen?

• Does any faster centralized version control than SVN exists?

  - by Savageman

  Hello, I've been using SVN since a long time and now we're trying on Git. I'm not talking on the centralized / decentralized debate here. My only concern is speed. The latter tool is much faster. But sometimes, I NEED to work with a centralized approach, which is much more simple and less complex than the decentralized one. The learning curve is really fast, which saves a lot of time (while digging into decentralized would lead to a waste of time, given the learning curve is much longer and we encounter more problem when working with it). However, SVN is really slow compared to GIT, and I don't think it has anything to do with the centralized argument. Decentralized systems also have to deal with server connections and file transfert. So I can easilly imagine a faster implementation of centralized version control could exists. Does someone has any clue on this?

• Web UI for showing like/dislike community comments side-by-side

  - by Justin Grant

  We want to add a comments/reviews feature to our website's plugin gallery, so users can not only vote up or down a particular plugin, but also leave an optional short comment about what they liked or didn't like about it. I'm looking for inspiration, ideally a good implementation elsewhere on the web which isn't annoying to end users, isn't impossibly complex to develop, and which enables users to see both good and bad comments side-by-side, like this: Like: 57 votes Dislike: 8 votes --------------------------------- -------------------------------- "great plugin, saved me hours..." "hard to install" "works well on MacOS and Ubuntu" "Broken on Windows Vista with UAC enabled" "integrates well with version 3.2" More... More... Anyone know a site which does something like this?

• Int PK inner join Vs Guid PK inner Join on SQL Server. Execution plan.

  - by bigb

  I just did some testing for Int PK join Vs Guid PK. Tables structure and number of records looking like that: Performance of CRUD operations using EF4 are pretty similar in both cases. As we know Int PK has better performance rather than strings. So SQL server execution plan with INNER JOINS are pretty different Here is an execution plan. As i understand according with execution plan from attached image Int join has better performance because it is taking less resources for Clustered index scan and it is go in two ways, am i right? May be some one may explain this execution plan in more details?

• Did Delphi ever get a for each loop?

  - by Ryan

  Hello, I've read that Delphi was supposed to get a for each loop in Delphi 9. Did this functionality ever make it into the language? My Delphi 2009 IDE doesn't seem to recognize the for each syntax. Here's my code: procedure ProcessDirectory(p_Directory, p_Output : string); var files : TStringList; filePath : string; begin files := GetSubfiles(p_Directory); try for (filePath in files.Strings) do begin // do something end; finally files.Free; end; end;

• creating an options menu with quit application function

  - by Domen Tomažin

  Hello, I'm writing an application for android and I would like to insert an options menu, that would have only one function and that is to quit an application. My options_menu.xml looks like this (I created a new folder under res called menu - just like the instructions said): Than I added the following code to my java class file: @Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.options_menu, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { // Handle item selection switch (item.getItemId()) { case R.id.quit: finish(); return true; default: return super.onOptionsItemSelected(item); } I also defined the @string/quit in values - strings.xml file, but it still says that there is an error: C:\Users\Domen\workspace\Lovne Dobe1.1\res\menu\options_menu.xml:3: error: Error: No resource found that matches the given name (at 'title' with value '@string/quit') So if anybody can help I would be very grateful.

• PHP Linefeeds (\n) Not Working

  - by dosboy

  For some reason I can't use \n to create a linefeed when outputting to a file with PHP. It just writes "\n" to the file. I've tried using "\\n" as well, where it just writes "\n" (as expected). But I can't for the life of me figure out why adding \n to my strings isn't creating new lines. I've also tried \r\n but it just appends "\r\n" to the line in the file. Example: error_log('test\n', 3, 'error.log'); error_log('test2\n', 3, 'error.log'); Outputs: test\ntest2\n Using MAMP on OSX in case that matters (some sort of PHP config thing maybe?). Any suggestions?

• What are the pro and cons of having localization files vs hard coded variables in source code?

  - by corgrath

  Definitions: Files: Having the localization phrases stored in a physical file that gets read at application start-up and the phrases are stored in the memory to be accessed via util-methods. The phrases are stored in key-value format. One file per language. Variables: The localization texts are stored as hard code variables in the application's source code. The variables are complex data types and depending on the current language, the appropriate phrase is returned. Background: The application is a Java Servlet and the developers use Eclipse as their primary IDE. Some brief pro and cons: Since Eclipse is use, tracking and finding unused localizations are easier when they are saved as variables, compared to having them in a file. However the application's source code becomes bigger and bloated. What are the pro and cons of having localization text in files versus hard coded varibles in source code? What do you do and why?

• Sql query: use where in or foreach?

  Hi, I'm using query, where the piece is: ...where code in ('va1','var2'...') I have about 50k of this codes. It was working when I has 30k codes, but know I get: The query processor ran out of internal resources and could not produce a query plan. This is a rare event and only expected for extremely complex queries or queries that reference a very large number of tables or partition I think that problem is related with IN... So now I'm planning use foreach(string code in codes) ...where code =code Is it good Idea ??

Do you see any negative points in useing Pango/Cairo. Well on MacOSX i havent succeded installing Pango/Cairo yet. Looks like a bad Omen. I would also like to hear about the performance penality. The first time i looked at Pango i thought, yes thats the reason why Software is still getting despite better hardware.

• How to add debug assemblies to my Silverlight 2 application?

  - by Steve Wortham

  So I know now that the debug assemblies have been intentionally left out of the Silverlight runtime to save space. For that reason I get good detailed error messages on my local machine that has the Silverlight SDK on it, but I don't on a computer with the runtime only. I get the ubiquitous, "Debugging resource strings are unavailable." Unfortunately my requirements are a bit unique. I need to include the debug assembly (not sure which one yet) that will give me details of a regular expression error. And so essentially I want to include the dll in the xap if I can. The problem is that I can't seem to do this. I've tried adding the debug dll's as references and setting them to "copy local." And I've tried adding them into the project as content. But in fact, with either method the xap hardly grows in size and the error message doesn't change. Any ideas?

• hash password in SQL Server (asp.net)

  - by ile

  Is this how hashed password stored in SQL Server should look like? This is function I use to hash password (I found it in some tutorial) public string EncryptPassword(string password) { //we use codepage 1252 because that is what sql server uses byte[] pwdBytes = Encoding.GetEncoding(1252).GetBytes(password); byte[] hashBytes = System.Security.Cryptography.MD5.Create().ComputeHash(pwdBytes); return Encoding.GetEncoding(1252).GetString(hashBytes); } EDIT I tried to use sha-1 and now strings seem to look like as they are suppose to: public string EncryptPassword(string password) { return FormsAuthentication.HashPasswordForStoringInConfigFile(password, "sha1"); } // example output: 39A43BDB7827112409EFED3473F804E9E01DB4A8 Result from the image above looks like broken string, but this sha-1 looks normal.... Will this be secure enough?

• How to disable UI control based on domain object's state?

  - by Subb

  Here's my problem. I have a somewhat complex domain object, which, depending on its state, responds to certain actions. I think the state pattern is pretty much the solution for that. However, I need to display which actions are possible at any moment in the UI. Ex: The domain object is an audio player. Some songs can't be skipped (like ads), so I need to disable the "next" and "previous" buttons in the GUI so the user have some kind of feedback of which action he can execute. I've looked at Swing's Action class (note: this is not a Java project), but I think I would need to keep every Actions in my domain object class (audio player), so it can enable or disable them depending on its own state (thus, affecting the UI). Is it the way to do it?

• Where can an absolute beginner of Kohana PHP go to learn how to use it from the ground up?

  - by Sergio Tapia

  Hi guys! I have a month of free time and I've decided to launch my own website. It's going to be big and have dymanic content where different users with different roles can perform modifications to the site. Place comments, rate stores, list items, etc. This sound like a perfect opportunity for me to expand my horizons and learn a PHP Framework. I've used PHP bare bones before but nothing too complex. As of now, do you think Kohana is a mature framework to use? I've used Zend in the past for a course in Uni but it sucked horribly, I was new to the MVC model, but Zend had pretty much zero workable tutorials and guides for newbies. That's why I hated it. Where can I go to learn how to use Kohana from a retarded starting point? Thank you very much for your time.

• List of fundamental data structures - what am I missing?

  - by jboxer

  I've been studying my fundamental data structures a bunch recently, trying to make sure I've got them down cold. By "fundamental", I mean the real basic ones. Fancy ones like Red-Black Trees and Bloom Filters are clearly worth knowing, but they're usually either enhancements of fundamental ones (Red-Black Trees are binary search trees with special properties to keep them balanced) or they're only useful in very specific situations (Bloom Filters). So far, I'm "fluent" in the following data structures: Arrays Linked Lists Stacks/Queues Binary Search Trees Heaps/Priority Queues Hash Tables However, I feel like I'm missing something. Are there any fundamental ones that I'm forgetting about? EDIT: Added these after posting the question Strings (suggested by catchmeifyoutry) Sets (suggested by Peter) Graphs (suggested by Nick D and aJ) B-Trees (Suggested by tloach) I'm a little on-the-fence about whether these are too fancy or not, but I think they're different enough from the fundamental structures (and important enough) to be worth studying as fundamental.

• In java getting different value for TimeZone.getDefault().getID() on different system

For example, in case of Indian standard time, On one of the system we are getting "GMT+5:30": while on another we are getting "Asia/Calcutta". We are expected to get "Asia/calcutta" strings on all machines. Why is there an inconsistency for such behavior? Is there any way to get consistent behavior across different systems windows/MAC? What is the best way to get client time zone programmatically using Java?
