• Sharepoint and SQL server Endpoint

  - by Usman Ahmad

  I created a LinkedServer on MS SQL Server 2005 pointing to my Active Directory. Nothing too fancy. Simple LinkedServer with ReadOnlyAdmin Account assigned to CONNECTAS Property. Then I created some storedprocedures to retreive some data from the LinkedServer. Again nothing too fancy. Just a few simple LDAP Queries. Then I created a SQL Endpoint to expose these stored procedures as Web services. Using Visual Studio 2008, everything is fine and dandy. It finds the endpoint, gets the list of the methods available and runs smoothly. Cool. But the Sharpeoint Add Web Service somehow doesn't work! It finds the WSDL file no prob. Retrieves the list of functions and parameterss n all but just simply doesn't run them! Any advice or where I should start checking?

• How to compare sqlite TIMESTAMP values

  - by Roel

  I have an Sqlite database in which I want to select rows of which the value in a TIMESTAMP column is before a certain date. I would think this to be simple but I can't get it done. I have tried this: SELECT * FROM logged_event WHERE logged_event.CREATED_AT < '2010-05-28 16:20:55' and various variations on it, like with the date functions. I've read http://sqlite.org/lang_datefunc.html and http://www.sqlite.org/datatypes.html and I would expect that the column would be a numeric type, and that the comparison would be done on the unix timestamp value. Apparantly not. Anyone who can help? If it matters, I'm trying this out in Sqlite Expert Personal.

• Right clicking on QHeaderView inside of QTreeView

  - by taynaron

  I've written a descendant of QTreeView with multiple columns. I want to create a popup menu that appears whe nthe user right-clicks over the column headers. I have tried catching signals from QTreeView for this, but QTreeView doesn't seem to emit signals on the headers. QTreeView.header() does. I therefore believe I must either: 1: connect one of QHeaderView's signals to a popup function - I have been unable to find a signal that is triggered on a single right click - I have tried sectionClicked, sectionHandleDoubleClicked, sectionDoubleClicked, sectionPressed (not surprised the double click functions didn't catch a single right click - but they do catch a double right click) self.header().sectionClicked.connect(self.headerMenu) self.header().sectionHandleDoubleClicked.connect(self.headerMenu) self.header().sectionDoubleClicked.connect(self.headerMenu) self.header().sectionPressed.connect(self.headerMenu) or, 2: write a descendant of QHeaderView with my own MousePressEvent function, and use that for my headers. I have so far been unsuccessful in connecting the new header class to the QTreeView descendant. I keep getting a Segmentation Fault on runtime, with no more explanation. #in DiceView's init, where DiceHeaders is the QHeaderView descendant self.setHeader(DiceHeaders()) Any ideas?

• Unit Testing in QTestLib - running single test / tests in class / all tests

  - by Dave

  I'm just starting to use QTestLib. I have gone through the manual and tutorial. Although I understand how to create tests, I'm just not getting how to make those tests convenient to run. My unit test background is NUnit and MSTest. In those environments, it was trivial (using a GUI, at least) to alternate between running a single test, or all tests in a single test class, or all tests in the entire project, just by clicking the right button. All I'm seeing in QTestLib is either you use the QTEST_MAIN macro to run the tests in a single class, then compile and test each file separately; or use QTest::qExec() in main() to define which objects to test, and then manually change that and recompile when you want to add/remove test classes. I'm sure I'm missing something. I'd like to be able to easily: Run a single test method Run the tests in an entire class Run all tests Any of those would call the appropriate setup / teardown functions.

• cygwin slow file open

  - by Erdem

  My application uses fopen to open a lot of files. While in linux opening and reading thousand of files doesn't even take a second; in cygwin it takes more than 5 seconds. I think it is because path conversion functions in cygwin dlls. 'open' function is a bit faster. If I use -mno-cygwin it becomes very fast but I can't use it. Is there an easy way to make cygwin dlls just open files; without any linux-windows conversion?

• Func<sometype,bool> to Func<T,bool>

  - by user175528

  If i have: public static Func<SomeType, bool> GetQuery() { return a => a.Foo=="Bar"; } and a generic version public static Func<T, bool> GetQuery<T>() { return (Func<T,bool>)GetQuery(); } how can I do the case? The only way I have found so far is to try and combine it with a mock function: Func<T, bool> q=a => true; return (Func<T, bool>)Delegate.Combine(GetQuery(), q); I know how to do that with Expression.Lambda, but I need to work with plain functions, not expression trees

• try/catch: errors or exceptions?

  - by Josh

  OK. I may be splitting hairs here, but my code isn't consistent and I'd like to make it so. But before I do, I want to make sure I'm going the right way. In practice this doesn't matter, but this has been bothering me for a while so I figured I'd ask my peers... Every time I use a try... catch statement, in the catch block I always log a message to my internal console. However my log messages are not consistent. They either look like: catch(err) { DFTools.console.log("someMethod caught an error: ",err.message); ... or: catch(ex) { DFTools.console.log("someMethod caught an exception: ",ex.message); ... Obviously the code functions properly either way but it's starting to bother me that I sometimes refer to "errors" and sometimes to "exceptions". Like I said, maybe I'm splitting hairs but which is the proper terminology? "Exception", or "Error"?

• Use of Hibernate 3.0 with EJB 3.0 & JPA

  - by SOA Nerd

  Where I'm working the guys that are sitting across from me are working on a project. This is a JavaEE app which uses Struts, Spring, EJB 3.0, JPA, and Hibernate 3.0. They are using EJB 3.0 entity beans with annotations. I've been asking them why Hibernate 3.0 is in this mix and noone can seem to tell me. It feels like they've included Hibernate 3.0 because they were told to but are not using it for anything that they can't get from EJB 3.0 entity beans/JPA. They're using CMP and accessing all of the database functions via EJBs. Can Hibernate give you anything in this setup that can't be provided by EJB 3.0/JPA?

• Compare two String with MySQL

  - by Scorpi0

  Hi, I wan't to compare two strings in a SQL request so I can retrieve the best match, the aim is to propose to an operator the best zip code possible. For example, in France, we have Integer Zip code, so I made an easy request : SELECT * FROM myTable ORDER BY abs(zip_code - 75000) This request returns first the data closest of Paris. Unfortunatelly, United Kingdom have zip code like AB421RS, so my request can't do it. I see in SQL Server a function 'Difference' : http://www.java2s.com/Code/SQLServer/String-Functions/DIFFERENCEworkoutwhenonestringsoundssimilartoanotherstring.htm But I use MySQL.. Is there anyone who have a good idea to do the trick in one simple request ? PS : the Levenshtein Distance will not do it, as I really wan't to compare string like if they were number. ABCDEF have to be closer to AWXYZ than to ZBCDEF.

• Css editor with certain features

  - by user255408

  I need a light css editor with certain functions. Already downloaded and tried a few apps but still no luck, none of them fit my requirements. Actually, there is one, CssEdit (or TextMate), but unfortunately i'm a windows user... Already tried: built-in NetBeans IDE css editor (btw nice editor, the one i'm using now for css) IntelJ IDE (very good html and css editor, but using the entire ide just for this - that's crazy) ArduoCss (very buggy in win7 environment) Notepad Notepad++ (it rules, but as i said, i need something more functional for css editing) Style Master ( if i don't find anything else, probably i'll choose this one) Stylizer ( also might be my choice, but it's black interface kills me, also extremy noob-oriented, i even couldn't find a way to see the source code) Some of the features i am looking for: grouping by comments like here snippets autocomplete, if i type for instance f-s, it should recognize and expand it to "font-size" property color picker The editor must have at least the first feature that i listed above. Sorry for my poor english.

• PHP/Cronjob: What is my Cronjobs problem?

  - by Marius

  Hello there, I have no idea whats going on. But I have a script that looks like this. Cron job refuses to run it: include_once 'class_lib/mime_mail/mimeDecode.php'; include_once 'class_lib/Mail/IMAPv2.php'; include_once 'inc-functions.php'; include_once "$_SERVER[DOCUMENT_ROOT]/class_lib/DbFuctioneer.php"; $dbFuctioneer = new DbFuctioneer(); Everything works well when I remove: $dbFuctioneer = new DbFuctioneer(); Even when DbFuctioneer() looks like this: <?php class DbFuctioneer { function dbCountMatches( $count) { return $count; } } Does Cron have a problem with Classes in his Jobs? Thank you for your time. Kind regards, Marius

• only update certain model attributes using Backbone.js

  - by Drew Dara-Abrams

  With Backbone, I'm trying to update and save to the server just one attribute: currentUser.save({hide_explorer_tutorial: 'true'}); but I don't want to send all the other attributes. Some of them are actually the output of methods on the server-side and so they are not actually true attributes with setter functions. Currently I'm using unset(attribute_name) to remove all the attributes that I don't want to update on the server. Problem is those attributes are then no longer available for local use. Suggestions on how to only save certain attributes to the server?

• 'Design By Contract' in C#

  - by IAmCodeMonkey

  I wanted to try a little design by contract in my latest C# application and wanted to have syntax akin to: public string Foo() { set { Assert.IsNotNull(value); Assert.IsTrue(value.Contains("bar")); _foo = value; } } I know I can get static methods like this from a unit test framework, but I wanted to know if something like this was already built-in to the language or if there was already some kind of framework floating around. I can write my own Assert functions, just don't want to reinvent the wheel.

• Graceful degradation on iPhone

  - by Seva Alekseyev

  How do I write a program for iPhone (Objective C++) that runs on OS 2.0 but takes advantage of 3.0 features if they're available? Example: copy&paste (class UIPasteboard). Nice feature to have, but I don't want to kill backward compatibility. Do I compile against SDK v. 3 or v. 2? If the latter, how do I create an instance of UIPasteboard, considering it's not declared in the headers? If the former, won't some C-linkage functions cause "unresolved reference" upon loading under OS 2.0?

• Redmon's Run As User not loading user's enviroment variables

  - by catfish

  I'm attempting to use Redmon http://www.winimage.com/misc/redmon/ to send print jobs to a custom C# application. Redmon "runs" (actually the Print Spooler) as SYSTEM but has an option to Run As User to allow your application to run under the user that printed the job. The problem is that it doesn't appear to load the user's environment. So calling functions like Path.GetTempPath() points to \windows\temp instead of the user's. Also when attempting to run Outlook 2007+ via MAPI calls (to add attachments) it reports form errors due to, I think, the temp folder location. Is there a way to "reload" a profile or atleast get your environment vars within the Impersonated application? The only ideas I've had so far is to rebuild the vars directly from the registry, but I want to avoid this since it's a hack around (avoiding implementation details and all that). Or making a stub program that Redmon calls which then properly Run As User with full profile the custom application. Any other items or tricks?

• SQL Server: avoiding hard coding of database name in cross-database views

  - by codeulike

  So, lets say you have two SQL Server Databases on the same server that reference each others tables in their Views, Functions and Stored Procedures. You know, things like this: use database_foo create view spaghetti as select f.col1, c.col2 from fusilli f inner join database_bar.dbo.conchigli c on f.id = c.id (I know that cross-database views are not very good practice, but lets just say you're stuck with it) Are there any good techniques to avoid 'hard coding' the database names? (So that should you need to occasionally re-point to a different database - for testing perhaps - you don't need to edit loads of views, fns, sps) I'm interested in SQL 2005 or SQL 2008 solutions. Cheers.

• Convert methods from Java-actionscript to ObjectiveC

  - by eco_bach

  Hi I'm tring to convert the following 3 methods from java-actionscript to Objective C. Part of my confusion I think is not knowing what Number types, primitives I should be using. ie in actionscript you have only Number, int, and uint. These are the 3 functions I am trying to convert public function normalize(value:Number, minimum:Number, maximum:Number):Number { return (value - minimum) / (maximum - minimum); } public function interpolate(normValue:Number, minimum:Number, maximum:Number):Number { return minimum + (maximum - minimum) * normValue; } public function map(value:Number, min1:Number, max1:Number, min2:Number, max2:Number):Number { return interpolate( normalize(value, min1, max1), min2, max2); } This is what I have so far -(float) normalize:(float*)value withMinimumValue:(float*)minimum withMaximumValue:(float*)maximum { return (value - minimum) / (maximum - minimum); } -(float) interpolate:(float*)normValue withMinimumValue:(float*)minimum withMaximumValue:(float*)maximum { return minimum + (maximum - minimum) * normValue; } -(float) map:(float*)value withMinimumValue1:(float*)min1 withMaximumValue1:(float*)max1 withMinimumValue2:(float*)min2 withMaximumValue2:(float*)max2 { return interpolate( normalize(value, min1, max1), min2, max2); }

• What to look for in estimating a PowerBuilder Conversion Project?

  - by tekiegreg

  Hi there, I've been trying to do a spec for a PowerBuilder 9 to 11.5 migration of a relatively complex application. Granted PowerBuilder is not really my specialty I'm having issues trying to justify an estimate for this part of the project (and the PowerBuilder people I've been talking with have had some personal issues lately and are out of communication). These are some of the metrics that we have seen and can evaluate: -PBL Files -Main Windows -Data Windows -Functions (no we don't have the source available on this project) What metrics in particular are helpful and how long would any given "unit" such as a Data Window take?

• How to time-delay email deliveries?

  - by Michael D

  I'm currently learning about the Drupal email functions, such as drupal_mail and hook_mail, and hook_mail_alter, and I have a problem before me where I'll need to be able to queue emails for delayed delivery. For example, an event signup notification that needs to wait for an hour after the event was registered by a user. And that email has user specific data, so can't be just a generic template email... I'm using the MailQ module, mainly for it's logging capabilities, but I wonder if it (or something else) could be modified to add a configurable delay function? Any ideas?

• Functional Programming - Lots of emphasis on recursion, why?

  - by peakit

  I am getting introduced to Functional Programming [FP] (using Scala). One thing that is coming out from my initial learnings is that FPs rely heavily on recursion. And also it seems like, in pure FPs the only way to do iterative stuff is by writing recursive functions. And because of the heavy usage of recursion seems the next thing that FPs had to worry about were StackoverflowExceptions typically due to long winding recursive calls. This was tackled by introducing some optimizations (tail recursion related optimizations in maintenance of stackframes and @tailrec annotation from Scala v2.8 onwards) Can someone please enlighten me why recursion is so important to functional programming paradigm? Is there something in the specifications of functional programming languages which gets "violated" if we do stuff iteratively? If yes, then I am keen to know that as well. PS: Note that I am newbie to functional programming so feel free to point me to existing resources if they explain/answer my question. Also I do understand that Scala in particular provides support for doing iterative stuff as well.

• fast algorithm implementation to sort very small set

  - by aaa

  hello. This is the problem I ran into long time ago. I thought I may ask your for your ideas. assume I have very small set of numbers (integers), 4 or 8 elements, that need to be sorted, fast. what would be the best approach/algorithm? my approach was to use the max/min functions. I guess my question pertains more to implementation, rather than type of algorithm. At this point it becomes somewhat hardware dependent , so let us assume Intel 64-bit processor with SSE3 . Thanks

• Dictionary with delegate or swith?

  - by Samvel Siradeghyan

  Hi, I am writting a parser, which call some functions dependent on some value. I can implement this logic with simple switch like this swith(some_val) { case 0: func0(); break; case 1: func1(); break; } or with delegates and dictinary like this delegate void some_delegate(); Dictinary some_dictinary = new Dictinary(); some_dictinary[0] = func0; some_dictinary[1] = func1; some_dictinary[some_value].Invoke(); Are this two metods equal and wich is prefered? Thanks.

• How do I use Python's itertools.groupby()?

  - by James Sulak

  I haven't been able to find an understandable explanation of how to actually use Python's itertools.groupby() function. What I'm trying to do is this: take a list - in this case, the children of an objectified lxml element - divide it into groups based on some criteria, and then later iterate over each of these groups separately. I've reviewed the documentation (http://docs.python.org/lib/itertools-functions.html), and the examples, (http://docs.python.org/lib/itertools-example.html), but I've had trouble trying to apply them beyond a simple list of numbers. So, how do I use of itertools.groupby()? Is there another technique I should be using? Pointers to good "prerequisite" reading would also be appreciated.

• SVN Delete with wildcard?

  - by David Lively

  I'm migrating a VSS repository to SVN and inadvertently included all of the _vti_cnf, *.scc files in the first check-in. I'd like to remove these from SVN. (Not permanently, of course - just in the HEAD). The application in question is quite large, and finding and deleting these files on a folder-by-folder basis will take forever. Suggestions? There must be some obvious way to do this, but the proximity of the weekend is interfering with my higher brain functions.
