  • JAXB unmarshal exclude specific element

    - by zigomir
    Hi everyone! I know for @XmlTransient annotation, but sometimes I need this element and in other use cases I really have to prevent it from unmarshaling, because it contains base64 text. So I need to exclude it because performance problems. Is there any way to dynamicly exclude one element from unmarshaling with JAXB?

  • Using Office 2007 extension (i.e. docx) for skin based On-Screen keyboard.

    - by Peymankh
    Hi guys, I'm creating a On-Screen keyboard for my application, and it supports skins as well. Here's what I'm doing with the skins, I have a folder which contains some images and a xml file which maps the images to the keyboard, I want to be able to have the folder as a zip file like in Office 2007 (.docx) and iPhone firmwares (.ipsw), I know I can simply zip the folder and change the extension, what I need to know is how to read the files in the code. Thanks in advance.

  • Windows 7 - pydoc from cmd

    - by Random_Person
    Okay, I'm having one of those moments that makes me question my ability to use a computer. This is not the sort of question I imagined asking as my first SO post, but here goes. Started on Zed's new "Learn Python the Hard Way" since I've been looking to get back into programming after a 10 year hiatus and python was always what I wanted. This book has really spoken to me. That being said, I'm having a serious issue with pydoc from the command. I've got all the directories in c:/python26 in my system path and I can execute pydoc from the command line just fine regardless of pwd - but it accepts no arguments. Doesn't matter what I type, I just get the standard pydoc output telling me the acceptable arguments. Any ideas? For what it's worth, I installed ActivePython as per Zed's suggestion. C:\Users\Chevee>pydoc file pydoc - the Python documentation tool pydoc.py <name> ... Show text documentation on something. <name> may be the name of a Python keyword, topic, function, module, or package, or a dotted reference to a class or function within a module or module in a package. If <name> contains a '\', it is used as the path to a Python source file to document. If name is 'keywords', 'topics', or 'modules', a listing of these things is displayed. pydoc.py -k <keyword> Search for a keyword in the synopsis lines of all available modules. pydoc.py -p <port> Start an HTTP server on the given port on the local machine. pydoc.py -g Pop up a graphical interface for finding and serving documentation. pydoc.py -w <name> ... Write out the HTML documentation for a module to a file in the current directory. If <name> contains a '\', it is treated as a filename; if it names a directory, documentation is written for all the contents. C:\Users\Chevee> EDIT: New information, pydoc works just fine in PowerShell. As a linux user, I have no idea why I'm trying to use cmd anyways--but I'd still love to figure out what's up with pydoc and cmd. EDIT 2: More new information. In cmd... c:\>python c:/python26/lib/pydoc.py file ...works just fine. Everything works just fine with just pydoc in PowerShell without me worrying about pwd, or extensions or paths.

  • Override Linq-to-Sql Datetime.ToString() Default Convert Values

    - by snmcdonald
    Is it possible to override the default CONVERT style? I would like the default CONVERT function to always return ISO8601 style 126. Steps To Reproduce: DROP TABLE DATES; CREATE TABLE DATES ( ID INT IDENTITY(1,1) PRIMARY KEY, MYDATE DATETIME DEFAULT(GETUTCDATE()) ); INSERT INTO DATES DEFAULT VALUES; INSERT INTO DATES DEFAULT VALUES; INSERT INTO DATES DEFAULT VALUES; INSERT INTO DATES DEFAULT VALUES; SELECT CONVERT(NVARCHAR,MYDATE) AS CONVERTED, CONVERT(NVARCHAR(4000),MYDATE,126) AS ISO, MYDATE FROM DATES WHERE MYDATE LIKE'Feb%' Output: CONVERTED ISO MYDATE --------------------------- ---------------------------- ----------------------- Feb 8 2011 12:17AM 2011-02-08T00:17:03.040 2011-02-08 00:17:03.040 Feb 8 2011 12:17AM 2011-02-08T00:17:03.040 2011-02-08 00:17:03.040 Feb 8 2011 12:17AM 2011-02-08T00:17:03.040 2011-02-08 00:17:03.040 Feb 8 2011 12:17AM 2011-02-08T00:17:03.040 2011-02-08 00:17:03.040 Linq-to-Sql calls CONVERT(NVARCHAR,@p) when I cast ToString(). However, I am displaying all my data in the ISO8601 format. I would like to override the database default if possible to CONVERT(NVARCHAR,@p,126). I am using Dynamic Linq-to-Sql as demoed by ScottGu to process my data. PropertyInfo piField = typeof(T).GetProperty(rule.field); if (piField != null) { Type typeField = piField.PropertyType; if (typeField.IsGenericType && typeField.GetGenericTypeDefinition().Equals(typeof(Nullable<>))) { filter = filter .Select(x => x) .Where(string.Format("{0} != null", rule.field)) .Where(string.Format("{0}.Value.ToString().Contains(\"{1}\")", rule.field, rule.data)); } else { filter = filter .Select(x => x) .Where(string.Format("{0} != null", rule.field)) .Where(string.Format("{0}.ToString().Contains(\"{1}\")", rule.field, rule.data)); } } I was hoping my property would convert the expression from CONVERT(NVARCHAR,@p) to CONVERT(NVARCHAR,@p,126), however I get a NotSupportedException: ... has no supported translation to SQL. public string IsoDate { get { if (SUBMIT_DATE.HasValue) { return SUBMIT_DATE.Value.ToString("o"); } else { return string.Empty; } } }

  • Whats the maximum key length in NSDictionary?

    - by x3ro
    Hey there, I'm currently working on an app which displays a bunch of files in a table, and you can add and remove them and whatsoever. To prevent duplicates in the table, I'd like to create a NSDictionary using the files full path as keys for another NSDictionary which contains all the file information, but I am a little concerned about the maximum key length of NSDictionary, and also whether this solution would be performance killer or not... Looking forward to your answers. Best regards, x3ro

  • Recommended textbook for machine-level programming?

    - by Norman Ramsey
    I'm looking at textbooks for an undergraduate course in machine-level programming. If the perfect book existed, this is what it would look like: Uses examples written in C or assembly language, or both. Covers machine-level operations such as two's-complement integer arithmetic, bitwise operations, and floating-point arithmetic. Explains how caches work and how they affect performance. Explains machine instructions or assembly instructions. Bonus if the example assembly language includes x86; triple bonus if it includes x86-64 (aka AMD64). Explains how C values and data structures are represented using hardware registers and memory. Explains how C control structures are translated into assembly language using conditional and unconditional branch instructions. Explains something about procedure calling conventions and how procedure calls are implemented at the machine level. Books I might be interested in would probably have the words "machine organization" or "computer architecture" in the title. Here are some books I'm considering but am not quite happy with: Computer Systems: A Programmer's Perspective by Randy Bryant and Dave O'Hallaron. This is quite a nice book, but it's a book for a broad, shallow course in systems programming, and it contains a great deal of material my students don't need. Also, it is just out in a second edition, which will make it expensive. Computer Organization and Design: The Hardware/Software Interface by Dave Patterson and John Hennessy. This is also a very nice book, but it contains way more information about how the hardware works than my students need. Also, the exercises look boring. Finally, it has a show-stopping bug: it is based very heavily on MIPS hardware and the use of a MIPS simulator. My students need to learn how to use DDD, and I can't see getting this to work on a simulator. Not to mention that I can't see them cross-compiling their code for the simulator, and so on and so forth. Another flaw is that the book mentions the x86 architecture only to sneer at it. I am entirely sympathetic to this point of view, but news flash! You guys lost! Write Great Code Vol I: Understanding the Machine by Randall Hyde. I haven't evaluated this book as thoroughly as the other two. It has a lot of what I need, but the translation from high-level language to assembler is deferred to Volume Two, which has mixed reviews. My students will be annoyed if I make them buy a two-volume series, even if the price of those two volumes is smaller than the price of other books. I would really welcome other suggestions of books that would help students in a class where they are to learn how C-language data structures and code are translated to machine-level data structures and code and where they learn how to think about performance, with an emphasis on the cache.

  • Kohanav3 ORM: calling where->find_all twice

    - by David Lawson
    When I do something like the following: $site = ORM::factory('site')->where('name', '=', 'Test Site')->find(); $users = $site->users; $deletedusers = $users->where('deleted', '=', '1')->find_all(); $nondeletedusers = $users->where('deleted', '=', '0')->find_all(); The contents of $deletedusers is correct, but the $nondeletedusers contains every non-deleted user, not just the ones in the loaded $site. What am I doing wrong?

  • How do you code up a pattern matching code block in scala?

    - by egervari
    How do you code a function that takes in a block of code as a parameter that contains case statements? For instance, in my block of code, I don't want to do a match or a default case explicitly. I am looking something like this myApi { case Whatever() => // code for case 1 case SomethingElse() => // code for case 2 } And inside of my myApi(), it'll actually execute the code block and do the matches. Help?

  • Optimising movement on hex grid

    - by Mloren
    I am making a turn based hex-grid game. The player selects units and moves them across the hex grid. Each tile in the grid is of a particular terrain type (eg desert, hills, mountains, etc) and each unit type has different abilities when it comes to moving over the terrain (e.g. some can move over mountains easily, some with difficulty and some not at all). Each unit has a movement value and each tile takes a certain amount of movement based on its terrain type and the unit type. E.g it costs a tank 1 to move over desert, 4 over swamp and cant move at all over mountains. Where as a flying unit moves over everything at a cost of 1. The issue I have is that when a unit is selected, I want to highlight an area around it showing where it can move, this means working out all the possible paths through the surrounding hexes, how much movement each path will take and lighting up the tiles based on that information. I got this working with a recursive function and found it took too long to calculate, I moved the function into a thread so that it didn't block the game but still it takes around 2 seconds for the thread to calculate the moveable area for a unit with a move of 8. Its over a million recursions which obviously is problematic. I'm wondering if anyone has an clever ideas on how I can optimize this problem. Here's the recursive function I'm currently using (its C# btw): private void CalcMoveGridRecursive(int nCenterIndex, int nMoveRemaining) { //List of the 6 tiles adjacent to the center tile int[] anAdjacentTiles = m_ThreadData.m_aHexData[nCenterIndex].m_anAdjacentTiles; foreach(int tileIndex in anAdjacentTiles) { //make sure this adjacent tile exists if(tileIndex == -1) continue; //How much would it cost the unit to move onto this adjacent tile int nMoveCost = m_ThreadData.m_anTerrainMoveCost[(int)m_ThreadData.m_aHexData[tileIndex].m_eTileType]; if(nMoveCost != -1 && nMoveCost <= nMoveRemaining) { //Make sure the adjacent tile isnt already in our list. if(!m_ThreadData.m_lPassableTiles.Contains(tileIndex)) m_ThreadData.m_lPassableTiles.Add(tileIndex); //Now check the 6 tiles surrounding the adjacent tile we just checked (it becomes the new center). CalcMoveGridRecursive(tileIndex, nMoveRemaining - nMoveCost); } } } At the end of the recursion, m_lPassableTiles contains a list of the indexes of all the tiles that the unit can possibly reach and they are made to glow. This all works, it just takes too long. Does anyone know a better approach to this?

  • How to report DataContext.SubmitChanges() progress with LINQ2SQL

    - by kzen
    If there is a foreach loop that contains DataContext.Customer.InsertOnSubmit(cust) for example: foreach (Object obj in collection) { Customer cust = new Customer { Id = obj.Id, Name = obj.Name ... }; DataContext.Customer.InsertOnSubmit(cust); } And outside of the loop there is a call to: DataContext.SubmittChanges(); Is there a way to obtain the SubmittChanges progress in order to report the progress back to the user (or a different approach without moving the SubmittChanges into the loop)?

  • LinkedList parameters in Java

    - by Walt
    Hi there, I created a program that contains linked lists that are passed various methods. While this works just fine in Java... a style checker program we have to use doesn't like it It says: Declaring variables, return values or parameters of type 'LinkedList' is not allowed. If I declare them as simply List then I don't have access to the methods I want. What should I do?
