• Database independent row level security solution

  - by Filip

  Hi, does anybody knows about Java/C# database independent authorization library. This library should support read, write, delete, insert actions across company organizational structure. Something like this: - user can see all documents - user can enter new document assigned to his unit - user can change all documents assigned to his unit and all subordinate units. - user can delete documents that are assigned to him I should also be able to create custom actions (besides read, write,...) connect them to certain class and assign that "security token" to user (e.g. document.expire). If there aren't any either free or commercial libraries, is there a book that could be useful in implementing this functionality? Thanks.

• sql server 2000 and for xml explicit

  - by Marcin

  Hi everyone, I've got a problem with using for xml explicit in SQL Server 2000 (so I can't use the new path() stuff from sql 2005/8) Essentially I have two tables and the XML structure I want to have is <xml> <table_1 field1="foo" field2="foobar2" field3="foobar3"> <a_row_from_table_2 field1="goo" field2="goobar2" field3="goobar3" /> <a_row_from_table_2 field1="hoo" field2="hoobar2" field3="hoobar3" /> </table_1> </xml> That is, table_1 has a one-to-many relationship with table_2, and I want to make a hierarchy of it. So far I can't seem to get it, the closest I've managed to get is all the records from table1, with all the records from table2 appended to the very last element of table1 Any help with setting up this kind of relationship would be greatly appreciated. -Marcin

• stringtemplate .net dynamic object

  - by Mark Milford

  Hi I am using string template to render some content, but the content may be variable so not sure how to pass it in (using .net / c#) Basic idea is I have a List which need to end up as parameters, e.g. List<KeyValuePair<string, object>> ret = new List<KeyValuePair<string, object>>(); ret.Add(new KeyValuePair<string, object>("elem1", true)); ret.Add(new KeyValuePair(string, object>("elem2", false)); Now I want these to show up in string template as: $item.elem1$ $item.elem2$ I can get them to be $elem1$ or $elem2$ but i need them inside of a structure. So I in effect need to convince the string template setAttribute that I'm passing in an object with properties elem1 and elem2 when in fact I have a List of KeyValuePairs. Thanks

• Good tools which generate NUnit unit tests for .NET assemblies in Visual Studio 2008

  - by andy

  Hey guys, I'm pretty new to Unit Testing so bare with me. I realize that best best practice is not to auto generate unit tests, however I'd like to use Code Generation to set-up the basic skeleton of the tests. Now, I know Visual Studio 2008 already has the built in "create tests", however, it just creates a flat list of all the classes it's going to test... and it's not for NUnit right? Ideally, I'd like the code generation to follow the folder AND namespace structure of the assembly its generating tests for. Can you guys recommend any good tools which generate NUnit unit tests for .NET assemblies in Visual Studio 2008? cheers!

• Is it viable and necessary to encrypt bytes?

  - by Shervin

  We have a requirement from customer that if someone gets access to the database, all data that includes personal information should be encrypted, so that when they do select calls, they shouldn't be able to see anything in clear text. Now this isn't any problem for Strings, but what about bytearrays? (that can potentially be quite huge (several 100mb)) When you do a select call, you get gibberish anyways. Is it possible for a hacker to somehow read the bytes and get the sensitive information without knowing how the structure of the object it is mapped against is? Because if that is the case, then I guess we should encrypt those bytes, even if they can potentially be quite huge. (I am guessing adding encryption will make them even bigger)

• How to handle BL cache for multiple web applications?

  - by Eran Betzalel

  I recently received a project that contains multiple web applications with no MVC structure. For starters I've created a library (DLL) that will contain the main Business Logic. The problem is with Caching - If I use the current web context cache object than I might end up with duplicate caching (as the web context will be different for every application). I'm currently thinking about implementing a simple caching mechanism with a singleton pattern that will allow the different web sites (aka different application domains) to share their "caching wisdom". I'd like to know what is the best way to solve this problem.

• Simple Linq Dynamic Query question

  - by Dr. Zim

  In Linq Dynamic Query, Scott Guthrie shows an example Linq query: var query = db.Customers. Where("City == @0 and Orders.Count >= @1", "London", 10). OrderBy("CompanyName"). Select("new( CompanyName as Name, Phone)"); Notice the projection new( CompanyName as Name, Phone). If I have a class like this: public class CompanyContact { public string Name {get;set;} public string Phone {get;set;} } How could I essentially "cast" his result using the CompanyContact data type without doing a foreach on each record and dumping it in to a different data structure? To my knowledge the only .Select available is the Dymanic Query version which only takes a string and parameter list.

• How to find unneccesary dependencies in a maven multi-project?

  - by hstoerr

  If you are developing a large evolving multi module maven project it seems inevitable that there are some dependencies given in the poms that are unneccesary, since they are transitively included by other dependencies. For example this happens if you have a module A that originally includes C. Later you refactor and have A depend on a module B which in turn depends on C. If you are not careful enough you'll wind up with both B and C in A's dependency list. But of course you do not need to put C into A's pom, since it is included transitively, anyway. Is there tool to find such unneccesary dependencies? (These dependencies do not actually hurt, but they might obscure your actual module structure and having less stuff in the pom is usually better. :-)

• LINQ to SQL join when there aren't results

  - by Boarder2

  Given the following database structure I'm trying to write a LINQ query that will return images grouped by tags it's associated with. So far I've got this: var images = from img in db.Images join imgTags in db.ImageTags on img.idImage equals imgTags.idImage join t in db.Tags on imgTags.idTag equals t.idTag where img.OCRData.Contains(searchText.Text) group img by new { t.TagName } into aGroup select new { GroupName = aGroup.Key.TagName, Items = from x in aGroup select new ImageFragment() { ImageID = x.idImage, ScanDate = x.ScanTime } }; Which works great. However, I also want to return Images that do not have any tags associated with them in a group of "(Untagged)" or something. I can't wrap my head around how I would do this without inserting a default tag for every image and that seems like generally not a very good solution.

• Django - categories & sub-categories

  - by Bluey

  Some advice needed on how I can structure my models for my site. I have seen this post from Django project but still a little lost. Also come across Django-MPTT - but that's no help and possibly overkill. I'm looking to have categories & subcategories that are shown in the URLs like this: mysite.com/Level1/Maths/Calculations/Addition/ mysite.com/Level3/English/ mysite.com/Level2/English/Storytelling/ In my admin interface I'm looking to have drop downs for each level of category or subcategory. Also at each level I will be querying items (another model) like get all items that have the category 'Level1' AND 'Maths'. There could also be a situation where I have five or more subcategories. How is it best to create my models for best performance? It it worth using tagging instead?

• how to read value of an xml node (single) using linq to xml

  - by Wondering

  Hi All, I have a xml structure similar to below one: <test> <test1>test1 value</test1> </test> Now I am reading the value of node using below LINQ to xml code. var test = from t in doc.Descendants("test") select t.Element("test1").Value; Console.WriteLine("print single node value"); Console.WriteLine(test); above code works fine, but here I have one single node, but to retrive value I am using foreach loop, which I dont think is good..any better way of doing the same thing without a foreach loop Thanks.

• Make VS 2008 Auto Deploy SQL Server CE 3.5 When Debugging on Windows Mobile 5.0 Device

  - by INTPnerd

  How do you make VS 2008 automatically install SQL Server CE 3.5 when debugging (F5) a CF app on a windows Mobile 5.0 device? VS used to do this automatically, but now it stopped and I don't know why. I have changed the structure of my solution and the projects, but it is still using SQL Server CE 3.5. It used to also install the Query Analyzer as well which was useful. I frequently uninstall all the programs on the device or do hard reboots so installing this manually is what I am trying to avoid.

• MySQL index cardinality - performance vs storage efficiency

  - by Sean

  Say you have a MySQL 5.0 MyISAM table with 100 million rows, with one index (other than primary key) on two integer columns. From my admittedly poor understanding of B-tree structure, I believe that a lower cardinality means the storage efficiency of the index is better, because there are less parent nodes. Whereas a higher cardinality means less efficient storage, but faster read performance, because it has to navigate through less branches to get to whatever data it is looking for to narrow down the rows for the query. (Note - by "low" vs "high", I don't mean e.g. 1 million vs 99 million for a 100 million row table. I mean more like 90 million vs 95 million) Is my understanding correct? Related question - How does cardinality affect write performance?

• How to document an XML Schema?

  - by lucas clemente

  I have developed a XML schema for an application I wrote. Now I want to document the valid structure for the end user, however I can't come up with any natural way to do this. I've seen things like xs3p, which essentially converts a xsd schema to a HTML representation, however that doesn't look like good documentation to me; the user shouldn't need to know anything about schemas to understand what he is allowed to do. Any ideas how to document this? Any programs / editors / graphical solutions or simply concepts I can build on?

• Level-order in Haskell

  - by brain_damage

  I have a structure for a tree and I want to print the tree by levels. data Tree a = Nd a [Tree a] deriving Show type Nd = String tree = Nd "a" [Nd "b" [Nd "c" [], Nd "g" [Nd "h" [], Nd "i" [], Nd "j" [], Nd "k" []]], Nd "d" [Nd "f" []], Nd "e" [Nd "l" [Nd "n" [Nd "o" []]], Nd "m" []]] preorder (Nd x ts) = x : concatMap preorder ts postorder (Nd x ts) = (concatMap postorder ts) ++ [x] But how to do it by levels? "levels tree" should print ["a", "bde", "cgflm", "hijkn", "o"]. I think that "iterate" would be suitable function for the purpose, but I cannot come up with a solution how to use it. Would you help me, please?

• change the class loading order google app engine java

  - by Shekhar

  I am trying to create an application on google app engine using struts2. Struts2 internally uses freemarker .One of the Freemarker framework classes suppose X internally uses a class javax.swing.Treenode which is not in google app engine jre white list. Now in order to run my application i created a new class X in the same package structure as it was in freemarker framework and copied the class to WEB-INF classes.Then When i run my application it run fine. The problem is that i want to take out the class X from my application sourcecode and move it to newly created jar and place it in WEB-INF/lib folder. So that i can reuse the code in multiple project and my code remains clean of the freemarker code. But when i run the application it picks the old class X from the original freemarker framework.As a result i get ClassNotFoundException. Can anyone provide any help such that i can change the ClassLoading order such that my jar containing X class loads first.

• Higher than high-level web frameworks or CMS's?

  - by Ben

  I'm looking for options that allow very high-level web site development with these special characteristics: not requiring the user to program in a complex programming language not requiring the user to use GUI-like administration areas allow the user to "program" in a lightweight markup language The last point is not only about look and structure of the output but also about creating simple dynamic output. For example: listing pages fetching the content of other pages doing a site search and displaying its output dynamically show or hide parts of the page depending on login status Of course, I am not expecting a solution that provides the same possibilities like a Ruby, Python or PHP web framework. Rather I am looking for support of the "basics" that are common for web sites. Until now, I have found only one piece of software that fulfills these requirements but while it's free, it's not open source: BoltWire at http://www.boltwire.com/. Being open source is required.

• .NET SortedDictionary But Sorted By Values

  - by Michael Covelli

  I need a data structure that acts like a SortedDictionary<int, double> but is sorted based on the values rather than the keys. I need it to take about 1-2 microseconds to add and remove items when we have about 3000 items in the dictionary. My first thought was simply to switch the keys and values in my code. This very nearly works. I can add and remove elements in about 1.2 microseconds in my testing by doing this. But the keys have to be unique in a SortedDictionary so that means that values in my inverse dictionary would have to be unique. And there are some cases where they may not be. Any ideas of something in the .NET libraries already that would work for me?

• Java: Last access of 2D HashMap

  - by JamieFlowers

  I have the following structure: HashMap< String, HashMap< String, String Now i want to know the last accessed element in the 2nd dimension. I know there is TreeMap which makes sense in the 1rst dimension but after that it doesn't make any sense. How can I keep track of a 2D HashMap ordering? With access i mean: value = hashmap.get("a").get("1") value = hashmap.get("b").get("2") value = hashmap.get("c").get("3") hashmap.removeLast(); hashmap.removeLast(); hashmap.removeLast();

• Lock Free Queue -- Single Producer, Multiple Consumers

  - by Shirish

  Hello, I am looking for a method to implement lock-free queue data structure that supports single producer, and multiple consumers. I have looked at the classic method by Maged Michael and Michael Scott (1996) but their version uses linked lists. I would like an implementation that makes use of bounded circular buffer. Something that uses atomic variables? On a side note, I am not sure why these classic methods are designed for linked lists that require a lot of dynamic memory management. In a multi-threaded program, all memory management routines are serialized. Aren't we defeating the benefits of lock-free methods by using them in conjunction with dynamic data structures? I am trying to code this in C/C++ using pthread library on a Intel 64-bit architecture. Thank you, Shirish

• Linq to SQL Error with Many-to-Many table

  - by Matt Connolly

  I am getting the following error with linq-to-sql when I try to access a many-to-many collection: Members 'Int32 XXX' and 'Int32 YYY' both marked as IsPrimaryKey and IsDbGenerated. The statement is true, in that both of those columns are primary key integers with identity insert. The table I am trying to access has a foreign key to both YYY and ZZZ, and then ZZZ has a foreign key to XXX. There doesn't appear to be anything wrong with my data structure. I tried setting "Child Property" to false on the ZZZ-YYY relationship, but it didn't change anything.

• Flex: Get an item from a AdvancedDataGrid given an index

  - by David Wolever

  I've got a subclass of AdvancedDataGrid showing a tree-like data structure. How can I, given the index returned by calculateDropIndex, get the item at that index? After reading through reams of code, it seems like the least terrible way is: var oldSelectedIndex:int = this.selectedIndex; var mouseOverIndex:int = this.calculateDropIndex(event); this.selectedItem = mouseOverIndex; var item:* = this.selectedItem; this.selectedIndex = oldSelectedIndex; The other option seems to be tinkering around with the iterator property... But, judging by the way I've seen it used, that will get pretty harry pretty quickly too. So, how can I get the item at a particular index in an advanced datagrid without going insane?

• Parsing complex string using regex

  - by wojtek_z

  My regex skills are not very good and recently a new data element has thrown my parser into a loop Take the following string "+USER=Bob Smith-GROUP=Admin+FUNCTION=Read/FUNCTION=Write" Previously I had the following for my regex : [+\\-/] Which would turn the result into USER=Bob Smith GROUP=Admin FUNCTION=Read FUNCTION=Write FUNCTION=Read But now I have values with dashes in them which is causing bad output New string looks like "+USER=Bob Smith-GROUP=Admin+FUNCTION=Read/FUNCTION=Write/FUNCTION=Read-Write" Which gives me the following result , and breaks the key = value structure. USER=Bob Smith GROUP=Admin FUNCTION=Read FUNCTION=Write FUNCTION=Read Write Can someone help me formulate a valid regex for handling this or point me to some key / value examples. Basically I need to be able to handle + - / signs in order to get combinations.

• speed up a sql query to mysql?

  - by fayer

  in my mysql database i've got the geonames database, containing all countries, states and cities. i am using this to create a cascading menu so the user could select where he is from: country - state - county - city. but the main problem is that the query will search through all the 7 millions rows in that table each time i want to get the list of children rows, and that is taking a while 10-15 seconds. i wonder how i could speed this up: caching? table views? reorganizing table structure somehow? and most important, how do i do these things? are there good tutorials you could link to me? i appreciate all help and feedback discussing smart ways of handling this issue!
