  • Auto-needed classes?

    - by fsdfa
    Suppose I have a class A and a class B. The .h of A, needs the .h of B, and the .h of B needs the .h of A. (need = #include). All .h have the guards: #ifndef _classX_ #define _classX_ ... ... #endif But if I compile the .cpp of A, then when it includes the .h of B, the B class cannot include the .h of A class because the A class has already use the guard. How can i solve this?

  • ATI propriatery drivers install latest 12.8, broke my kernel. Stuck on kernel 3.2.0-26

    - by user66987
    I messed up a bit. Hoping some here can help me. I tried to install the newest catalyst 12.8. Sadly, this broke my system. I was stuck in low graphics mode. I finally managed to restore the proprietary drivers, and get into ubuntu again. But now I am stuck on kernel 3.2.0.26. I had installed kernel 3.2.0-30, but the system no longer sees it. I have kernel 3.2.0-29 too, but the system cannot see that as well. In the grub menu. When I use sudo update-grub, they are both listed. Here are the output I get: Searching for GRUB installation directory ... found: /boot/grub Cannot determine root device. Assuming /dev/hda1 This error is probably caused by an invalid /etc/fstab Searching for default file ... found: /boot/grub/default Testing for an existing GRUB menu.lst file ... found: /boot/grub/menu.lst Searching for splash image ... none found, skipping ...

  • What is the problem with the logic in my UPDATE statement?

    - by Stefan Åstrand
    Hello, I would appreciate some help with an UPDATE statement. I want to update tblOrderHead with the content from tblCustomer where the intDocumentNo corresponds to the parameter @intDocumentNo. But when I run the my statement, the order table is only updated with the content from the first row of the customer table. What is the problem with my logic? I use Microsoft SQL Server. Thanks, Stefan UPDATE dbo.tblOrderHead SET dbo.tblOrderHead.intCustomerNo = @intCustomerNo , dbo.tblOrderHead.intPaymentCode = dbo.tblCustomer.intPaymentCode, dbo.tblOrderHead.txtDeliveryCode = dbo.tblCustomer.txtDeliveryCode, dbo.tblOrderHead.txtRegionCode = dbo.tblCustomer.txtRegionCode, dbo.tblOrderHead.txtCurrencyCode = dbo.tblCustomer.txtCurrencyCode, dbo.tblOrderHead.txtLanguageCode = dbo.tblCustomer.txtLanguageCode FROM dbo.tblOrderHead INNER JOIN dbo.tblCustomer ON dbo.tblOrderHead.intOrderNo = @intDocumentNo

  • SQL Server 2005 RIGHT OUTER JOIN not working

    - by CheeseConQueso
    I'm looking up access logs for specific courses. I need to show all the courses even if they don't exist in the logs table. Hence the outer join.... but after trying (presumably) all of the variations of LEFT OUTER, RIGHT OUTER, INNER and placement of the tables within the SQL code, I couldn't get my result. Here's what I am running: SELECT (a.first_name+' '+a.last_name) instructor, c.course_id, COUNT(l.access_date) course_logins, a.logins system_logins, MAX(l.access_date) last_course_login, a.last_login last_system_login FROM lsn_logs l RIGHT OUTER JOIN courses c ON l.course_id = c.course_id, accounts a WHERE l.object_id = 'LOGIN' AND c.course_type = 'COURSE' AND c.course_id NOT LIKE '%TEST%' AND a.account_rights > 2 AND l.user_id = a.username AND ((a.first_name+' '+a.last_name) = c.instructor) GROUP BY c.course_id, a.first_name, a.last_name, a.last_login, a.logins, c.instructor ORDER BY a.last_name, a.first_name, c.course_id, course_logins DESC Is it something in the WHERE clause that's preventing me from getting course_id's that don't exist in lsn_logs? Is it the way I'm joining the tables? Again, in short, I want all course_id's regardless of their existence in lsn_logs.

  • Need help joining tables...

    - by yuudachi
    I am a MySQL newbie, so sorry if this is a dumb question.. These are my tables. student table: SID (primary) student_name advisor (foreign key to faculty.facultyID) requested_advisor (foreign key to faculty.facultyID) faculty table: facultyID (primary key) advisor_name I want to query a table that shows everything in the student table, but I want advisor and requested_advisor to show up as names, not the ID numbers. so like it displays like this on the webpage: Student Name: Jane Smith SID: 860123456 Current Advisor: John Smith Requested advisor: James Smith not like this Student Name: Jane Smith SID: 860123456 Current Advisor: 1 Requested advisor: 2 SELECT student.student_name, SID, student_email, faculty.advisor_name FROM student INNER JOIN faculty ON student.advisor = faculty.facultyID; this comes out close, but I don't know how to get the requested_advisor to show up as a name.

  • How can I make an SQL statement that finds unassociated records?

    - by William Calleja
    I have two tables as follows: tblCountry (countryID, countryCode) tblProjectCountry(ProjectID, countryID) The tblCountry table is a list of all countries with their codes and the tblProjectCountry table associates certain countries with certain projects. I need an SQL statement that gives me a list of the countries with their country code that do NOT have an associated record in the tblProjectCountry table. so far I got to here: SELECT tblCountry.countryID, tblCountry.countryCode FROM tblProjectCountry INNER JOIN tblCountry ON tblProjectCountry.countryID = tblCountry.countryID WHERE (SELECT COUNT(ProjectID) FROM tblProjectCountry WHERE (ProjectID = 1) AND (countryID = tblCountry.countryID)) = 0 The above statement parses as correct but doesn't give the exact result I'm looking for. Can anyone help?

  • querying databases on same server with linq

    - by geoff swartz
    In normal sql I could do joins on tables in different databases as long as they were on the same server (or linked servers). In linq I can't figure out how to do that. Is this possible? For example, if I have a database called db1 and another called db2. db1 has a table called people and db2 has a table called address I could do something like... select a.addressline1, p.firstname from db1.dbo.people p inner join db2.dbo.address a on p.peopleid = a.peopleid Is this possible with linq? Thanks.

  • Linq To Sql Left outer join - filtering null results

    - by Harry
    I'd like to reproduce the following SQL into C# LinqToSql SELECT TOP(10) Keywords.* FROM Keywords LEFT OUTER JOIN IgnoreWords ON Keywords.WordID = IgnoreWords.ID WHERE (DomainID = 16673) AND (IgnoreWords.Name IS NULL) ORDER BY [Score] DESC The following C# Linq gives the right answer. But I can't help think I'm missing something (a better way of doing it?) var query = (from keyword in context.Keywords join ignore in context.IgnoreWords on keyword.WordID equals ignore.ID into ignored from i in ignored.DefaultIfEmpty() where i == null where keyword.DomainID == ID orderby keyword.Score descending select keyword).Take(10); the SQL produced looks something like this: SELECT TOP (10) [t0].[DomainID], [t0].[WordID], [t0].[Score], [t0].[Count] FROM [dbo].[Keywords] AS [t0] LEFT OUTER JOIN (SELECT 1 AS [test], [t1].[ID] FROM [dbo].[IgnoreWords] AS [t1]) AS [t2] ON [t0].[WordID] = [t2].[ID] WHERE ([t0].[DomainID] = 16673) AND ([t2].[test] IS NULL) ORDER BY [t0].[Score] DESC How can I get rid of this redundant inner selection? It's only slightly more expensive but every bit helps!

  • MySQL Query, limit output display according/only to associated ID!

    - by Jess
    So here's my situation. I have a books table and authors table. An author can have many books... In my authors page view, the user (logged in) can click an author in a tabled row and be directed to a page displaying the author's books (collected like this URI format: viewauthorbooks.php?author_id=23), very straight forward... However, in my query, I need to display the books for the author only, and not all books stored in the books table (as i currently have!) As I am a complete novice, I used the most simple query of: SELECT * FROM tasks_tb :)....this returns the books for me, but returns every single value (book) in the database, and not ones associated with the selected author. And when I click a different author the same books are displayed for them...I think everyone gets what I'm trying to achieve, I just don't know how to perform the query. I'm guessing that I need to start using more advanced query clauses like INNER JOIN etc. Anyone care to help me out :)

  • What is wrong with my SQL syntax for an UPDATE with a JOIN?

    - by Phil H
    I have two tables, related by a common key. So TableA has key AID and value Name and TableB has keys AID, BID and values Name, Value: AID Name 74 Alpha AID BID Name Value 74 4 Beta Brilliance I would like to update the TableB Value here from Brilliance to Barmy, using just the Name fields. I thought I could do it via an UPDATE containing a JOIN, but Access (I know...) is complaining with 'Syntax error (missing operator) in query expression ' and then everything from 'Barmy' here: UPDATE tB SET tB.BValue='Barmy' FROM TableB tB INNER JOIN TableA tA ON tB.AID=tA.AID WHERE tB.Name='Beta' AND tA.Name='Alpha'; What is my heinous crime? Or is it just Access not conforming?

  • How do I classify using GLCM and SVM Classifier in Matlab?

    - by Gomathi
    I'm on a project of liver tumor segmentation and classification. I used Region Growing and FCM for liver and tumor segmentation respectively. Then, I used Gray Level Co-occurence matrix for texture feature extraction. I have to use Support Vector Machine for Classification. But I don't know how to normalize the feature vectors. Can anyone tell how to program it in Matlab? To the GLCM program, I gave the tumor segmented image as input. Was I correct? If so, I think, then, my output will also be correct. My glcm coding, as far as I have tried is, I = imread('fzliver3.jpg'); GLCM = graycomatrix(I,'Offset',[2 0;0 2]); stats = graycoprops(GLCM,'all') t1= struct2array(stats) I2 = imread('fzliver4.jpg'); GLCM2 = graycomatrix(I2,'Offset',[2 0;0 2]); stats2 = graycoprops(GLCM2,'all') t2= struct2array(stats2) I3 = imread('fzliver5.jpg'); GLCM3 = graycomatrix(I3,'Offset',[2 0;0 2]); stats3 = graycoprops(GLCM3,'all') t3= struct2array(stats3) t=[t1;t2;t3] xmin = min(t); xmax = max(t); scale = xmax-xmin; tf=(x-xmin)/scale Was this a correct implementation?

  • "initialization error: class file has wrong version" message in JDeveloper 10.1.2.x

    - by [email protected]
    The "initialization error: class file has wrong version" has become a somewhat recurrent error message thrown by JDeveloper 10.1.2.x as newer JDKs have been released in the last years. Note that JDeveloper 10.1.2 was developed to run with JDK 1.4.2. The reasons for this error message to be thrown include: A JDK version higher than 1.4.2 is being used and some unexpected incompatibility conflicts can occur because of that Some of the libraries used on the workspace and/or project were compiled with newer JDK version So, it is strongly recommended to use newer JDeveloper versions (10.1.3 - 11g) for newer JDKs. JDeveloper 10.1.2 will be desupported in December 2010 (or later depending on the support contract). Further information about this can be seen at http://www.oracle.com/support/library/brochure/lifetime-support-middleware.pdf

  • A really simple ViewModel base class with strongly-typed INotifyPropertyChanged

    - by Daniel Cazzulino
    I have already written about other alternative ways of implementing INotifyPropertyChanged, as well as augment your view models with a bit of automatic code generation for the same purpose. But for some co-workers, either one seemed a bit too much :o). So, back on the drawing board, we came up with the following view model authoring experience:public class MyViewModel : ViewModel, IExplicitInterface { private int value; public int Value { get { return value; } set { this.value = value; RaiseChanged(() =&gt; this.Value); } } double IExplicitInterface.DoubleValue { get { return value; } set { this.value = (int)value; RaiseChanged(() =&gt; ((IExplicitInterface)this).DoubleValue); } } } ...Read full article

  • Help to understand the abstract factory pattern

    - by Chobeat
    I'm learning the 23 design patterns of the GoF. I think I've found a way to understand and simplify how the Abstract Factory works but I would like to know if this is a correct assumption or if I am wrong. What I want to know is if we can see the result of the Abstract Factory method as a matrix of possible products where there's a Product for every "Concrete Factory" x "AbstractProduct" where the Concrete Factory is a single implementation among the implementations of an AbstractFactory and an AbstractProduct is an interface among the interfaces to create Products. Is this correct or am I missing something?

  • Should I use a Class or Dictionary to Store Form Values

    - by Shamim Hafiz
    I am working on a C# .NET Application, where I have a Form with lots of controls. I need to perform computations depending on the values of the controls. Therefore, I need to pass the Form values to a function and inside that function, several helper functions will be called depending on the Control element. Now, I can think of two ways to pass all the Form values: i) Save everything in a Dictionary and pass the Dictionary to the function or ii) Have a class with attributes that corresponds to each of the Form element.

  • How do I classify using SVM Classifier in Matlab?

    - by Gomathi
    I'm on a project of liver tumor segmentation and classification. I used Region Growing and FCM for liver and tumor segmentation respectively. Then, I used Gray Level Co-occurence matrix for texture feature extraction. I have to use Support Vector Machine for Classification. But I don't know how to normalize the feature vectors. Can anyone tell how to program it in Matlab? To the GLCM program, I gave the tumor segmented image as input. Was I correct? If so, I think, then, my output will also be correct. I gave the parameters exactly as in the example provided in the documentation itself. The output I obtained was stats = autoc: [1.857855266614132e+000 1.857955341199538e+000] contr: [5.103143332457753e-002 5.030548650257343e-002] corrm: [9.512661919561399e-001 9.519459060378332e-001] corrp: [9.512661919561385e-001 9.519459060378338e-001] cprom: [7.885631654779597e+001 7.905268525471267e+001] cshad: [1.219440700252286e+001 1.220659371449108e+001] dissi: [2.037387269065756e-002 1.935418927908687e-002] energ: [8.987753042491253e-001 8.988459843719526e-001] entro: [2.759187341212805e-001 2.743152140681436e-001] homom: [9.930016927881388e-001 9.935307908219834e-001] homop: [9.925660617240367e-001 9.930960070222014e-001] maxpr: [9.474275457490587e-001 9.474466930429607e-001] sosvh: [1.847174384255155e+000 1.846913030238459e+000] savgh: [2.332207337361002e+000 2.332108469591401e+000] svarh: [6.311174784234007e+000 6.314794324825067e+000] senth: [2.663144677055123e-001 2.653725436772341e-001] dvarh: [5.103143332457753e-002 5.030548650257344e-002] denth: [7.573115918713391e-002 7.073380266499811e-002] inf1h: [-8.199645492654247e-001 -8.265514568489666e-001] inf2h: [5.643539051044213e-001 5.661543271625117e-001] indnc: [9.980238521073823e-001 9.981394883569174e-001] idmnc: [9.993275086521848e-001 9.993404634013308e-001] The thing is, I run the program for three images.

  • Puppet : How to override / redefine outside child class (usecase and example detailled)

    - by alex8657
    The use case i try to illustrate is when to declare some item (eq mysqld service) with a default configuration that could be included on every node (class stripdown in the example, for basenode), and still be able to override this same item in some specific class (eg mysql::server), to be included by specific nodes (eg myserver.local) I illustrated this use case with the example below, where i want to disable mysql service on all nodes, but activate it on a specific node. But of course, Puppet parsing fails because the Service[mysql] is included twice. And of course, class mysql::server bears no relation to be a child of class stripdown Is there a way to override the Service["mysql"], or mark it as the main one, or whatever ? I was thinking about the virtual items and the realize function, but it only permits apply an item multiple times, not to redefine or override. # In stripdown.pp : class stripdown { service {"mysql": enable => "false", ensure => "stopped" } } # In mysql.pp : class mysql::server { service { mysqld: enable => true, ensure => running, hasrestart => true, hasstatus => true, path => "/etc/init.d/mysql", require => Package["mysql-server"], } } # Then nodes in nodes.pp : node basenode { include stripdown } node myserver.local inherits basenode { include mysql::server` # BOOM, fails here because of Service["mysql"] redefinition }

  • A sample Memento pattern: Is it correct?

    - by TheSilverBullet
    Following this query on memento pattern, I have tried to put my understanding to test. Memento pattern stands for three things: Saving state of the "memento" object for its successful retrieval Saving carefully each valid "state" of the memento Encapsulating the saved states from the change inducer so that each state remains unaltered Have I achieved these three with my design? Problem This is a zero player game where the program is initialized with a particular set up of chess pawns - the knight and queen. Then program then needs to keep adding set of pawns or knights and queens so that each pawn is "safe" for the next one move of every other pawn. The condition is that either both pawns should be placed, or none of them should be placed. The chessboard with the most number of non conflicting knights and queens should be returned. Implementation I have 4 classes for this: protected ChessBoard (the Memento) private int [][] ChessBoard; public void ChessBoard(); protected void SetChessBoard(); protected void GetChessBoard(int); public Pawn This is not related to memento. It holds info about the pawns public enum PawnType: int { Empty = 0, Queen = 1, Knight = 2, } //This returns a value that shown if the pawn can be placed safely public bool IsSafeToAddPawn(PawnType); public CareTaker This corresponds to caretaker of memento This is a double dimentional integer array that keeps a track of all states. The reason for having 2D array is to keep track of how many states are stored and which state is currently active. An example: 0 -2 1 -1 2 0 - This is current state. With second index 0/ 3 1 - This state has been saved, but has been undone private int [][]State; private ChessBoard [] MChessBoard; //This gets the chessboard at the position requested and assigns it to originator public ChessBoard GetChessBoard(int); //This overwrites the chessboard at given position public void SetChessBoard(ChessBoard, int); private int [][]State; public PlayGame (This is the originator) private bool status; private ChessBoard oChessBoard; //This sets the state of chessboard at position specified public SetChessBoard(ChessBoard, int); //This gets the state of chessboard at position specified public ChessBoard GetChessBoard(int); //This function tries to place both the pawns and returns the status of this attempt public bool PlacePawns(Pawn);

  • Comparing the Performance of Visual Studio&apos;s Web Reference to a Custom Class

    As developers, we all make assumptions when programming. Perhaps the biggest assumption we make is that those libraries and tools that ship with the .NET Framework are the best way to accomplish a given task. For example, most developers assume that using <a href="http://www.4guysfromrolla.com/articles/120705-1.aspx">ASP.NET's Membership system</a> is the best way to manage user accounts in a website (rather than rolling your own user account store). Similarly, creating a Web Reference to communicate with a <a href="http://www.4guysfromrolla.com/articles/100803-1.aspx">web service</a> generates markup that auto-creates a <i>proxy class</i>, which handles the low-level details of invoking the web service, serializing parameters,

  • Steam, launching Team Fortress 2: libGL.so.1: wrong ELF class: ELFCLASS64

    - by stefanhgm
    After I got Steam running with the workaround mentioned here, I've got nearly the same problem when launching Team Fortress 2. After starting it from Steam the "Launcher" pops up and after a few seconds it disappears with the following error in the terminal: /home/user/Steam/SteamApps/steamuser/Team Fortress 2/hl2_linux: error while loading shared libraries: libGL.so.1: wrong ELF class: ELFCLASS64 Game removed: AppID 440 "Team Fortress 2", ProcID 5299 saving roaming config store to 'sharedconfig.vdf' roaming config store 2 saved successfully Because of the similarity with the workaround I used before, I tried to execute: export LD_LIBRARY_PATH=/usr/lib32:$LD_LIBRARY_PATH directly before launching the game, but there is no difference.

  • Is it bad practice to pass instances through several layers?

    - by Puckl
    In my program design, I often come to the point where I have to pass object instances through several classes. For example, if I have a controller that loads an audio file, and then passes it to a player, and the player passes it to the playerRunnable, which passes it again somewhere else etc. It looks kind of bad, but I don´t know how to avoid it. Or is it OK to do this? EDIT: Maybe the player example is not the best because I could load the file later, but in other cases that does not work.

  • Servlet : Usage of Constants.java class vs context param

    - by Pongsakorn Semsuwan
    I'm just wondering whether to keep some of my variables in Constants class or keep it in web.xml Say, I want to keep a variable of Facebook graph API prefix or api_key, client_id From my understand, the difference between Constants.java and web.xml is web.xml is easier to rewrite on compile using ant. So, you can replace your variables in web.xml according to what environment you are building you app for. (client_id varies by development environment/production environment, for example) If I understand it right, then Facebook graph API prefix should be kept in Constants.java (because it always is "https://graph.facebook.com/") and api_key, client_id should be kept in web.xml? What's the proper way to use them?

  • Question for class

    - by Tyler
    I have a question for class that I cannot figure out, I was hoping the helpful folks at Ask Ubuntu could help. The question is basically this: Your Linux system appears to have a DHCP problem. You decide to release and renew the DHCP lease by running the following command "SUDO IFCONFIG ETH0 DOWN". The command gives an error message saying Linux doesn't recognize the command. What's the problem? Any ideas? Thanks in advance.
