  • Why C# calls different overloaded method for different values of same type?

    - by Fabio Veronez
    Hello all, I have one doubt concerning c# method overloading call resolution. Let's suppose I have the following C# code: enum MyEnum { Value1, Value2 } public void test() { method(0); // this calls method(MyEnum) method(1); // this calls method(object) } public void method(object o) { } public void method(MyEnum e) { } Note that I know how to make it work but I would like to know why for one value of int (0) it calls one method and for another (1) it calls another. It sounds awkward since both values have the same type (int) but they are "linked" for different methods. Ps.: This is my first question here, i'm sorry if I made something wrong. =P

  • Spacewalk 2.0 provided to manage Oracle Linux systems

    - by wcoekaer
    Oracle Linux customers have a few options to manage and provision their servers. We provide a license to use Oracle Enterprise Manager's Linux OS management, monitoring and provisioning features without additional cost for every server that has an Oracle Linux support subscription. So there is no additional pack to license and no additional per server cost, it's all included in our Basic, Premier and Systems support subscriptions. The nice thing with Oracle Enterprise Manager is that you end up with a single management product that can manage all aspects of your software stack. You have complete insight into the applications running, you have roles and responsibilities, you have third party connectors for storage or other products and it makes it very easy and convenient to correlate data and events when something happens. If you use Oracle VM as well, you end up with a complete cloud portal with selfservice, chargeback, etc... Another, much simpler option, is just using yum. It is very easy to take a server and create directories and expose these through apache as repositories. You can have a simple yum config on each server pointing to a few specific repositories. It requires some manual effort in terms of creating directories, downloading packages and creating local repo files but it's easy to do and for many people a preferred solution. There are also a good number of customers that just connect their servers directly to ULN or to our free update server public-yum. Just to re-iterate, our public-yum servers have all the errata and updates available for free. Now we added another option. Many of our customers have switched from a competing Linux vendor and they had familiarity with their management tools. Switching to Oracle for support is very easy since we don't require changes to the installed servers but we also want to make sure there is a very easy and almost transparent switch for the management tools as well. While Oracle Enterprise Manager is our preferred way of managing systems, we now are offering Spacewalk 2.0 to our customers. The community project can be found here. We have made a few changes to ensure easy and complete support for Oracle Linux, tested it with public-yum, etc.. You can find the rpms in our public-yum repos at http://public-yum.oracle.com/repo/OracleLinux/OL6/. There are repositories for spacewalk server and then for each version (OL5,OL6) and architecture (x86 and x86-64) we have the client repositories as well. Spacewalk itself is only made available for OL6 x86-64. Documentation can be found here. I set it up myself and here are some quick steps on how you can get going in just a matter of minutes: Spacewalk Server Installation : 1) Installing an Oracle Database Use an existing Oracle Database or install a new Oracle Database (Standard or Enterprise Edition) [at this time use 11g, we will add support for 12c in the near future]. This database can be installed on the spacewalk server or on a separate remote server. While Oracle XE might work to create a small sample POC, we do not support the use of Oracle XE, spacewalk repositories can become large and create a significant database workload. Customers can use their existing database licenses, they can download the database with a trial licence from http://edelivery.oracle.com or Oracle Linux subscribers (customers) will be allowed to use the Oracle Database as a spacewalk repository as part of their Oracle Linux subscription at no additional cost. |NOTE : spacewalk requires the database to be configured with the UTF8 characterset. |Installation will fail if your database does not use UTF8. |To verify if your database is configured correctly, run the following command in sqlplus: | |select value from nls_database_parameters where parameter='NLS_CHARACTERSET'; |This should return 'AL32UTF8' 2) Configure the database schema for spacewalk Ideally, create a tablespace in the database to hold the spacewalk schema tables/data; create tablespace spacewalk datafile '/u01/app/oracle/oradata/orcl/spacewalk.dbf' size 10G autoextend on; Create the database user spacewalk (or use some other schema name) in sqlplus. example : create user spacewalk identified by spacewalk; grant connect, resource to spacewalk; grant create table, create trigger, create synonym, create view, alter session to spacewalk; grant unlimited tablespace to spacewalk; alter user spacewalk default tablespace spacewalk; 4) Spacewalk installation and configuration Spacewalk server requires an Oracle Linux 6 x86-64 system. Clients can be Oracle Linux 5 or 6, both 32- and 64bit. The server is only supported on OL6/64bit. The easiest way to get started is to do a 'Minimal' install of Oracle Linux on a server and configure the yum repository to include the spacewalk repo from public-yum. Once you have a system with a minimal install, modify your yum repo to include the spacewalk repo. Example : edit /etc/yum.repos.d/public-yum-ol.repo and add the following lines at the end of the file : [spacewalk] name=spacewalk baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/spacewalk20/server/$basearch/ gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6 gpgcheck=1 enabled=1 Install the following pre-requisite packages on your spacewalk server : oracle-instantclient11.2-basic-11.2.0.3.0-1.x86_64 oracle-instantclient11.2-sqlplus-11.2.0.3.0-1.x86_64 rpm -ivh oracle-instantclient11.2-basic-11.2.0.3.0-1.x86_64 rpm -ivh oracle-instantclient11.2-sqlplus-11.2.0.3.0-1.x86_64 The above RPMs can be found on the Oracle Technology Network website : http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html As the root user, configure the library path to include the Oracle Instant Client libraries : cd /etc/ld.so.conf.d echo /usr/lib/oracle/11.2/client64/lib oracle-instantclient11.2.conf ldconfig Install spacewalk : # yum install spacewalk-oracle The above yum command should download and install all required packages to run spacewalk on your local server. | NOTE : if you did a full, desktop or workstation installation, | you have to remove the JTA package | BEFORE installing spacewalk-oracle (rpm -e --nodeps jta) Once the installation completes, simply run the spacewalk configuration tool and you are all set. (make sure to run the command with the 2 arguments) spacewalk-setup --disconnected --external-db Answer the questions during the setup, ensure you provide the current database user (example : spacewalk) and password (example : spacewalk) and database server hostname (the standard hostname of the server on which you have deployed the Oracle database) At the end of the setup script, your spacewalk server should be fully configured and you can log into the web portal. Use your favorite browser to connect to the website : http://[spacewalkserverhostname] The very first action will be to create the main admin account.

  • Web Crawling Sites with Javascripts or web forms

    - by Jojo
    Hello everyone, I have a webcrawler application. It successfully crawled most common and simple sites. Now i ran into some types of websites wherein HTML documents are dynamically generated through FORMS or javascripts. I believe they can be crawled and I just don't know how. Now, these websites do not show the actual HTML page. I mean if I browse that page in IE or firefox, the HTML code does not match what's actually in the IE or firefox. These sites contain textboxes, checkboxes, etc... so I believe they are what they call "Web Forms". Actually I am not much familiar with web development so correct me if I'm wrong. My question is, does anyone in similar situation as I am now and have successfully solved these types of "challenges"? Does anyone know of a certain book or article regarding web crawling? Those that pertains to these advanced type of websites? Thanks.

  • What could make GetCursorPos return incorrect coordinates of {0,0} ?

    - by Dave Moore
    We are seeing bad behavior in an application when it runs on Server 2008 (not R2). This is a WinForms application, and Control.MousePosition is returning {0,0} no matter where the mouse is on the screen... Control.MousePosition just makes a P/Invoke call to Win32 api GetCursorPos(). There is a control in our library that calls SetWindowsHookEx to hook WH_CALLWNDPROCRET for our entire process. I'm suspicious of this code, but tracing statements show that we're getting in + out of that hook cleanly. What else should I be looking for? Thanks, Dave

  • Using one sqlconnection/sqlcommand through 2 DB-bound methods

    - by dotnetdev
    I have a class with a method which gets data from a database through a SELECT stored proc. This method uses a SqlDbReader by returning ExecuteReader() on a SqlCommand. The connection and everything is made in this method, with fields (such as connection string) set as class level fields. I now need to populate an array based on the results of this query (so the columns of each row will go into the array with its own index). However, this query will not select all of the data from one table which is involved. I can write the queries to get what I need, but how can I use one connection throughout the class? If I instantiate the connection object and call Open() in the constructor, I get an exception @ runtime. I'm hoping for something like this: // At class level: sqlconn.Open(); // sqlcommand set up Method() { // Fire stored proc // Insert results in a collection } Method2() { // Pass same collection in (use same one), // Add new row columns into same collection } How can I do this with strict performance in mind? Thanks

  • Google App Engine and Git best practices

    - by systempuntoout
    I'm developing a small pet project on Google App Engine and i would like to keep code under source control using github; this will allow a friend of mine to checkout and modify the sources. I just have a directory with all sources (call it PetProject) and Google App Engine development server points to that directory. Is it correct to create a repo directly from PetProject directory or is it preferable to create a second directory mirroring the develop PetProject directory? In the latter case, anytime my friend will release something new, i need to pull fetch from Git copying the modified files to the develop PetProject directory. If i decide to keep the repo inside the develop directory, skipping .git on Gae yaml is enough? What are the best practices here?

  • How can I refactor this to use an inline function or template instead of a macro?

    - by BillyONeal
    Hello, everyone :) I have a useful macro here: #define PATH_PREFIX_RESOLVE(path, prefix, environment) \ if (boost::algorithm::istarts_with(path, prefix)) { \ ExpandEnvironmentStringsW(environment, buffer, MAX_PATH); \ path.replace(0, (sizeof(prefix)/sizeof(wchar_t)) - 1, buffer); \ if (Exists(path)) return path; \ } It's used about 6 times within the scope of a single function (that's it), but macros seem to have "bad karma" :P Anyway, the problem here is the sizeof(prefix) part of the macro. If I just replace this with a function taking a const wchar_t[], then the sizeof() will fail to deliver expected results. Simply adding a size member doesn't really solve the problem either. Making the user supply the size of the constant literal also results in a mess of duplicated constants at the call site. Any ideas on this one?

  • How to decode a JSON String with several objects in PHP?

    - by ilnur777
    Hi, guys! I know how to decode a JSON string with one object with your help from this example http://stackoverflow.com/questions/2543389/how-to-decode-a-json-string But now I would like to improve decoding JSON string with several objects and I can't understand how to do it. Here is an example: { "programmers": [ { "firstName": "Brett", "lastName":"McLaughlin" }, { "firstName": "Jason", "lastName":"Hunter" }, { "firstName": "Elliotte", "lastName":"Harold" } ], "authors": [ { "firstName": "Isaac", "lastName": "Asimov" }, { "firstName": "Tad", "lastName": "Williams" }, { "firstName": "Frank", "lastName": "Peretti" } ], "musicians": [ { "firstName": "Eric", "lastName": "Clapton" }, { "firstName": "Sergei", "lastName": "Rachmaninoff" } ] } How to decode this JSON, call data and display on the page from what object the informartion list is being read? Thank you!

  • Basic question about std::vector instantiation

    - by recipriversexclusion
    This looks simple but I am confused: The way I create a vector of hundred, say, ints is std::vector<int> *pVect = new std::vector<int>(100); However, looking at std::vector's documentation I see that its constructor is of the form explicit vector ( size_type n, const T& value= T(), const Allocator& = Allocator() ); So, how does the previous one work? Does new call the constructor with an initialization value obtained from the default constructor? If that is the case, would std::vector<int, my_allocator> *pVect = new std::vector<int>(100, my_allocator); where I pass my own allocator, also work?

  • Unit Test to Run .sql script to SQL Create Database

    - by Lee Englestone
    Can anyone point me in the direction of how I could get a NUnit test to run a .sql file to Create / Setup a database. I know about the the TestFixtureSetUp and TestFixtureTearDown attributes / methods in NUnit. So I KNOW how to call methods before and after all or each unit tests. I'm just unsure of how to load and execute the contents of a .sql file agains a SQL Server 2005 database programatically. Any examples? This is part of our TDD / CI. We are wanting to create the database before and tear down the database after executing unit tests. Cheers, -- Lee

  • What is the ambiguity in this piece of code?

    - by cambr
    #include <iostream> using namespace std; class A { public: void eat(){ cout<<"A";} }; class B: public A { public: void eat(){ cout<<"B";} }; class C: public A { public: void eat(){ cout<<"C";} }; class D: public B,C { public: void eat(){ cout<<"D";} }; int main(){ A *a = new D(); a->eat(); } I am not sure this is called diamond problem or not, but why doesn't this work? When I said, a->eat() (remember eat() is not virtual), there is only one possible eat() to call, that of A. Why then, do I get this error: 'A' is an ambiguous base of 'D'

  • Writing a Compiler for .net - IL or Bytecode?

    - by Michael Stum
    I'm currently diving into the inner workings of .net, which means IL. As an exercise, I want to build a brainf..k compiler for .net (yes, they already exist, but as said it's for learning purposes). For the moment I'm just writing some text files that contain .il and compile them with ilasm, which works. But I wonder if I could/should go one level deeper and write bytecode directly? My "concern" is the Windows PE Stuff when compiling an EXE - instead of ilasm I would need some sort of Bytecode linker that would take my MSIL/CIL bytecode and generate the PE Stuff for it? Or do compilers "only" compile their language to IL and execute ilasm? Is there a managed version of it that I can call/embed from my compiler?

  • spring web application context is not loaded from jar file in WEB-INF/lib when running tomcat in eclipse

    - by Remy J
    I am experimenting with spring, maven, and eclipse but stumbling on a weird issue. I am running Eclipse Helios SR1 with the STS (Spring tools suite) plugin which includes the Maven plugin also. What i want to achieve is a spring mvc webapp which uses an application context loaded from a local application context xml file, but also from other application contexts in jar files dependencies included in WEB-INF/lib. What i'd ultimately like to do is have my persistence layer separated in its own jar file but containing its own spring context files with persistence specific configuration (e.g a jpa entityManagerFactory for example). So to experiment with loading resources from jar dependencies, i created a simple maven project from eclipse, which defines an applicationContext.xml file in src/main/resources Inside, i define a bean <bean id="mybean" class="org.test.MyClass" /> and create the class in the org.test package I run mvn-install from eclipse, which generates me a jar file containing my class and the applicationContext.xml file: testproj.jar |_META-INF |_org |_test |_MyClass.class |_applicationContext.xml I then create a spring mvc project from the Spring template projects provided by STS. I have configured an instance of Tomcat 7.0.8 , and also an instance of springSource tc Server within eclipse. Deploying the newly created project on both servers works without problem. I then add my previous project as a maven dependency of the mvc project. the jar file is correctly added in the Maven Dependencies of the project. In the web.xml that is generated, i now want to load the applicationContext.xml from the jar file as well as the existing one generated for the project. My web.xml now looks like this: org.springframework.web.context.ContextLoaderListener <!-- Processes application requests --> <servlet> <servlet-name>appServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value> classpath*:applicationContext.xml, /WEB-INF/spring/appServlet/servlet-context.xml </param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>appServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> Also, in my servlet-context.xml, i have the following: <context:component-scan base-package="org.test" /> <context:component-scan base-package="org.remy.mvc" /> to load classes from the jar spring context (org.test) and to load controllers from the mvc app context. I also change one of my controllers in org.remy.mvc to autowire MyClass to verify that loading the context has worked as intended. public class MyController { @Autowired private MyClass myClass; public void setMyClass(MyClass myClass) { this.myClass = myClass; } public MyClass getMyClass() { return myClass; } [...] } Now this is the weird bit: If i deploy the spring mvc web on my tomcat instance inside eclipse (run on server...) I get the following error : org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping#0': Initialization of bean failed;

  • How do I get code coverage of Perl cgi script when executed by Selenium?

    - by Kurt W. Leucht
    I'm using Eclipse EPIC IDE to write some Perl cgi scripts which call some Perl modules that I have also written. The EPIC IDE lets me configure a Perl CGI "run configuration" which runs my CGI script. And then I've got Selenium set up and one of my unit test files runs some Selenium commands to run my cgi script through its paces. But the coverage report from Module::Build dispatch 'testcover' doesn't show that any of my module code has been executed. It's been executed by my cgi script, but I guess the CGI script was run manually and was not executed directly by my unit test file, so maybe that's why the coverage isn't being recognized. Is there a way to do this right so I can integrate Selenium and unit test files and code coverage all together somehow?

  • Accessing a dictionary value by custom object value in Python?

    - by Sam
    So I have a square that's made up of a series of points. At every point there is a corresponding value. What I want to do is build a dictionary like this: class Point: def __init__(self, x, y): self._x = x self._y = y square = {} for x in range(0, 5): for y in range(0, 5): point = Point(x,y) square[point] = None However, if I later create a new point object and try to access the value of the dictionary with the key of that point it doesn't work.. square[Point(2,2)] Traceback (most recent call last): File "<pyshell#19>", line 1, in <module> square[Point(2,2)] KeyError: <__main__.Point instance at 0x02E6C378> I'm guessing that this is because python doesn't consider two objects with the same properties to be the same object? Is there any way around this? Thanks

  • Qt: Writing plugins for other applications

    - by Rasmus Faber
    I am writing a plugin for another application. I want to support the plugin on multiple platforms, so I am strongly considering using Qt. The plugin needs to be able to show some basic GUI. The plugin interface does not in any way handle GUI - it is just a simple DLL/shared library specified with a C-header file. Can I use Qt inside such a shared library? The calling application might or might not be using Qt itself. Any hints on what to do? Do I need to run a QApplication event-loop in a separate thread? Or can I just call the event-loop myself while waiting for input? (I only need modal dialogs).

  • On Ubuntu, how do you install a newer version of python and keep the older python version?

    - by Trevor Boyd Smith
    Background: I am using Ubuntu The newer python version is not in the apt-get repository (or synaptic) I plan on keeping the old version as the default python when you call "python" from the command line I plan on calling the new python using pythonX.X (X.X is the new version). Given the background, how do you install a newer version of python and keep the older python version? I have downloaded from python.org the "install from source" *.tgz package. The readme is pretty simple and says "execute three commands: ./configure; make; make test; sudo make install;" If I do the above commands, will the installation overwrite the old version of python I have (I definitely need the old version)?

  • Why Use PHP OOP over Basic Functions and When?

    - by Codex73
    There are some posts about this matter, but I didn't clearly get when to use Object Oriented coding and when to use programmatic functions in an include. Somebody also mentioned to me that OOP is very heavy to run, and makes more workload. Is this right? Lets say I have a big file with 50 functions, why will I want to call these in a class? and not by function_name(). Should I switch and create object which holds all of my functions? What will be the advantage or specific difference? What benefits does it bring to code OOP in php ? Modularity?

  • Is it possible to replace groovy method for existing object?

    - by Jean Barmash
    The following code tried to replace an existing method in a Groovy class: class A { void abc() { println "original" } } x= new A() x.abc() A.metaClass.abc={-> println "new" } x.abc() A.metaClass.methods.findAll{it.name=="abc"}.each { println "Method $it"} new A().abc() And it results in the following output: original original Method org.codehaus.groovy.runtime.metaclass.ClosureMetaMethod@103074e[name: abc params: [] returns: class java.lang.Object owner: class A] Method public void A.abc() new Does this mean that when modify the metaclass by setting it to closure, it doesn't really replace it but just adds another method it can call, thus resulting in metaclass having two methods? Is it possible to truly replace the method so the second line of output prints "new"? When trying to figure it out, I found that DelegatingMetaClass might help - is that the most Groovy way to do this?

  • ANDing javascript objects together

    - by Jonas
    I ran across this chunk of code (modified) in our application, and am confused to how it works: function someObject() { this.someProperty = {}; this.foo = { bar: { baz: function() { return "Huh?" } } }; this.getValue = function() { return (this.someProperty && this.foo.bar && this.foo.bar.baz && this.foo.bar.baz()) || null; } } function test() { var o = new someObject(); var val = o.getValue(); alert(val); } when you call the test() function, the text "Huh?" is alerted. I'm not sure how the result of getValue is returning that, I would've thought doing A && B && C && D would have returned true, rather than the value of D.
