• How do I specify an assembly file name for a compiled ASP.NET application?

  - by CSharp Noob

  I have read under: Compiling Web Application Projects (http://msdn.microsoft.com/en-us/library/aa983464.aspx) ... this compilation model creates a single assembly, you can specify attributes, such as assembly name and version. You can supply a PATH (directory name only) in the Visual Studio "Build Options". But where can the file name for the assembly be specified?

• ADF vs. EJB/Spring: Where should I invest my time?

  - by Arthur Huxley

  I am a junior Java SE developer, planning to become a Java Standard Edition professional. Which technologies/frameworks will be the smartest thing for me to learn? I will invest a lot of time and energy on the technologies that I eventually choose and it will be the basis for my carreer. I need to choose carefully. I have one question in particular regarding Oracle ADF: How can it be better than Spring or EJB 3.x? No offense to the ADF developers - and please excuse my ignorance - but is there a reason for using ADF other than locking customers to Oracle products? If ADF is an inferior technology I fear I will be making a mistake choosing to specialize in ADF.

• How do i select the 1st and then every 4th row in a html-table with nth-child()-selector?

  - by Nils

  Ok, math isn't my strong side, I admit it. All I want to do is to select the first, 5th, 9th, 13th, 17th etc row in a html-table. Can anybody with better math-skills point me in the right directionor perhaps supply a "nth-child-for-dummies" guide? I tried nth-child(1n+4) (which selects the 4th row and everyone after), and i also tried nth-child(0n+4) which selects the fourth row and nothing after that. Thanks in advance.

• Using RhinoMocks, how do you mock or stub a concrete class without an empty constructor?

  - by Mark Rogers

  Mocking a concrete class with Rhino Mocks seems to work pretty easy when you have an empty constructor on a class: public class MyClass{ public MyClass() {} } But if I add a constructor that takes parameters and remove the one that doesn't take parameters: public class MyClass{ public MyClass(MyOtherClass instance) {} } I tend to get an exception: System.MissingMethodException : Can't find a constructor with matching arguments I've tried putting in nulls in my call to Mock or Stub, but it doesn't work. Can I create mocks or stubs of concrete classes with Rhino Mocks, or must I always supply (implicitly or explicitly) a parameter-less constructor?

• Wix Bootstrapper - difficulty detecting if software is already installed c++ redistributable, sql server ce 3.5 sp2

  - by gdeck

  I apologize if this is answered elsewhere. So far (thanks to a post from Rob Mensching), my code will detect .NET 4.0 if it's installed and it'll pass right over it. I'm not able to correctly detect Microsoft Visual C++ 2010 x86 Redistributable OR Microsoft SQL Server Compact 3.5 Service Pack 2. My code is below. I'm learning, so I would appreciate as much constructive criticism as possible. <!--Search for .NET 4.0--> <util:RegistrySearch Id="NETFRAMEWORK40" Root="HKLM" Key="SOFTWARE\Microsoft\Net Framework Setup\NDP\v4\Full" Value="Install" Variable="NETFRAMEWORK40" Result="value"/> <!--Search for Microsoft Visual C++ 2010 x86 Redistributable--> <util:RegistrySearch Id="SearchForCPP2010X86" Root="HKLM" Key="SOFTWARE\Microsoft\VisualStudio\10.0\VC\VCRedist\x86" Value="Install" Variable="CPP2010Redist" Result="exists"/> <!--Search for Microsoft SQL Server Compact 3.5 Service Pack 2--> <util:RegistrySearch Id="SearchForSQLSvrCE35SP2" Root="HKLM" Key="SOFTWARE\Microsoft\Microsoft SQL Server Compact Edition\v3.5\ENU" Value="Install" Variable="SQLSvrCE35SP2" Result="exists"/> <Chain> <!-- Install .Net 4 Full --> <PackageGroupRef Id="Net4Full"/> <!-- Install Microsoft Visual C++ 2010 x86 Redistributable --> <PackageGroupRef Id="MSVisCPP2010x86Redist"/> <!-- Install Microsoft SQL Server Compact 3.5 Service Pack 2 --> <PackageGroupRef Id="SQLExpressCE"/> </Chain> <!--Install .NET 4.0--> <PackageGroup Id="Net4Full"> <ExePackage Id="Net4Full" Name="Microsoft .NET Framework 4.0 Setup" Cache="no" Compressed="yes" PerMachine="yes" Permanent="yes" Vital="yes" SourceFile="BootstrapperLibrary\dotNetFx40_Full_setup.exe" DetectCondition="NETFRAMEWORK40"/> </PackageGroup> <!--Install Microsoft Visual C++ 2010 x86 Redistributable--> <PackageGroup Id="MSVisCPP2010x86Redist"> <ExePackage Id="MSVisCPP2010x86Redis" Name="Microsoft Visual C++ 2010 x86 Redistributable " Cache="no" Compressed="yes" PerMachine="yes" Permanent="yes" Vital="yes" SourceFile="BootstrapperLibrary\vcredist_x86.exe" DetectCondition="CPP2010Redist"/> </PackageGroup> <!--Install Microsoft SQL Server Compact 3.5 Service Pack 2--> <PackageGroup Id="SQLExpressCE"> <ExePackage Id="SQLExpressCE" Name="Microsoft SQL Server Compact 3.5 Service Pack 2 Setup" Cache="no" Compressed="yes" PerMachine="yes" Permanent="yes" Vital="yes" SourceFile="BootstrapperLibrary\SSCERuntime-ENU.exe"/> </PackageGroup>

• Python datetime to Unix timestamp

  - by Off Rhoden

  I have to create an "Expires" value 5 minutes in the future, but I have to supply it in UNIX Timestamp format. I have this so far, but it seems like a hack. def expires(): '''return a UNIX style timestamp representing 5 minutes from now''' epoch = datetime.datetime(1970, 1, 1) seconds_in_a_day = 60 * 60 * 24 five_minutes = datetime.timedelta(seconds=5*60) five_minutes_from_now = datetime.datetime.now() + five_minutes since_epoch = five_minutes_from_now - epoch return since_epoch.days * seconds_in_a_day + since_epoch.seconds Is there a module or function that does the timestamp conversion for me?

• What is the Dojo equivalent of jQuery's scope attribute?

  - by joolss

  Hi. I'm a Dojo n00b. In jQuery, a DOM node or jQuery object can be passed as an attribute in a query, which sets the scope: var myScope = $('#someDiv'); $('a',myScope).addClass('red'); $('li',myScope).css('display','inline'); Now, in Dojo I can chain several .query()s after each other, but what should I do if I have a certain DOM node - not a nodeList - that I want to use as a scope?

• Mapping java.util.Date to xs:date instead of xs:dateTime in JAX-WS

  - by Larsing

  Hi all, We hav an EJB, jws-anotated as a web service. It has a pretty complex pojo-model that generates an equally complex xsd. The pojos contain numerous java.util.Date. These all map to xs:dateTime. This service is used as "business service" in Oracle(BEA) OSB(AquaLogic). We also have a "proxy service" which we map to the BS with XQuery (the OSB/AquaLogic way). The proxy service's xsd has xs:date for the corresponding fields. For some reason, Oracle's implementation of XQuery does not support casting from xs:date to xs:dateTime(!). I could solve this by casting to xs:string and concat:ing with "T00:00:00", however, i would rather try to get JAX-WS to generate an xsd with xs:date instead. Only, I can't find any info on how to do this (anotations?). Can anyone give me a hint? Kind regards, Lars

• Create a CSR in C# using an explicit RSA key-pair

  - by rlandster

  Using the OpenSSL libraries one can create a CSR (certificate signing request) by doing this: openssl genrsa -out rsa.key 1024 openssl req -new -key rsa.key -out output.csr -config config.txt where config.txt contains the distinguished name to use in the certificate. I would like to do something similar under Windows using C#. However, the method createPKCS10 does not require you to supply an RSA key. Is there a way to get C# to generate an explicit RSA private key and then use that private key to create the CSR?

• Large ResultSet on postgresql query

  - by tuler

  I'm running a query against a table in a postgresql database. The database is on a remote machine. The table has around 30 sub-tables using postgresql partitioning capability. The query will return a large result set, something around 1.8 million rows. In my code I use spring jdbc support, method JdbcTemplate.query, but my RowCallbackHandler is not being called. My best guess is that the postgresql jdbc driver (I use version 8.3-603.jdbc4) is accumulating the result in memory before calling my code. I thought the fetchSize configuration could control this, but I tried it and nothing changes. I did this as postgresql manual recomended. This query worked fine when I used Oracle XE. But I'm trying to migrate to postgresql because of the partitioning feature, which is not available in Oracle XE. My environment: Postgresql 8.3 Windows Server 2008 Enterprise 64-bit JRE 1.6 64-bit Spring 2.5.6 Postgresql JDBC Driver 8.3-603

• Refactoring many nested ifs or chained if statements

  - by Icarus

  Hi, I have an object with large number of similar fields (like more than 10 of them) and I have to assign them values from an array of variable length. The solution would be either a huge nested bunch of ifs based on checking length of array each time and assigning each field OR a chain of ifs checking on whether the length is out of bounds and assigning each time after that check. Both seem to be repetitive. Is there a better solution ?

• Problem with launching JAGUAR in R

  - by Gerry

  Windows XP, R 2.11.1, Java JRE6 I just installed the Jaguar package. From an R console, I can do this: > library(JGR) Loading required package: rJava Loading required package: JavaGD Loading required package: iplots Please use the corresponding JGR launcher to start JGR. Run JGR() for details. You can also use JGR(update=TRUE) to update JGR. and so JGR appears to be correctly installed. JGR() yields On Windows JGR must be started using the JGR.exe launcher. Please visit http://www.rosuda.org/JGR/ to download it. > I'm not sure how to run Jaguar - I know I have to run jgr.exe - but should R be already open? If so, should the JGR library be already loaded? I've tried all of these, and what seems to happen regardless is a console window opens briefly, then disappears. I've run jrg --debug, with no apparent error message: (same file regardless of choice made above). What should I be doing? Thanks!

• Getting a visitors Facebook page

  - by Mr Carl

  Hey guys, this is more of a question out of curiosity, but is it possible to get somebody's Facebook page after they have visited your site? Was thinking maybe a chain of lookup stuff could be used starting with an IP to eventually perhaps get a name and thus that person's Facebook page. I have also heard you can read somebody's web history, is this true?

• unit test for proxy checking

  Proxy configuration of a machine can be easily fetched using def check_proxy(): import urllib2 http_proxy = urllib2.getproxies().get('http') I need to write a test for the above written function. In order to do that I need to:- Set the system-wide proxy to an invalid URL during the test(sounds like a bad idea). Supply an invalid URL to http_proxy. How can I achieve either of the above?

• What is a good approach for a Data Access Layer?

  - by Adil Mughal

  Our software is a customized Human Resource Management System (HRMS) using ASP.NET with Oracle as the database and now we are actually moving to make it a product that supports multiple tenants with their own databases. Our options: Use NHibernate to support Multiple databases and use of OO. But we concern related to NHibernate learning curve and any problem we faced. Make a generalized DAL which will continue working with Oracle using stored procedures and use tools to convert it to other databases such as SQL Server or MySql. There is a risk associated with having to support multiple database-dependent versions of a single script. Provide the software as a Service (SaaS) and maintain the way we conduct business. However there can may be clients who do not want or trust the Cloud or other SaaS business models. With this in mind, what's the best Data access layer technique?

• performance of parameterized queries for different db's

  - by tuinstoel

  A lot of people know that it is important to use parameterized queries to prevent sql injection attacks. Parameterized queries are also much faster in sqlite and oracle when doing online transaction processing because the query optimizer doesn't have to reparse every parameterized sql statement before executing. I've seen sqlite becoming 3 times faster when you use parameterized queries, oracle can become 10 times faster when you use parameterized queries in some extreme cases with a lot of concurrency. How about other db's like mysql, ms sql, db2 and postgresql? Is there an equal difference in performance between parameterized queries and literal queries?

• Application Runs when Debugging but not when Published.

  - by corymathews

  When publishing my web application and then running it will return the error "Could not load file or assembly 'BaseApplicationName' or one of its dependencies. An attempt was made to load a program with an incorrect format." However if I run the application through debugging (f5) it runs correctly. I guess what it comes down to is what differences are there when running an application through debugging vs publishing it that would cause a problem like this? When publising I have it set to delete all existing. History of how it started... I added the 32 bit Oracle.DataAccess dll to my 64 bit system. It would not work and crash giving the same error as above but with the Oracle.DataAccess name instead of the baseApplicationName. I have since removed all references to it and removed the dll to try and get it to run without it once again. Any advice?

• Spring vs Hibernate

  - by Vidar

  Just trying to get my head round Spring and figuring out how I wire up an Oracle connection in xml config file, and now find out I need yet another framework! - Hibernate, this is soooo frustrating as it feels like I'm getting deeper and deeper into more and more frameworks without actually getting what I need done! I looked at Hibernate and it seems to do similar things to Spring, bearing in mind I just want to do some SQL inserts in Oracle. I am reluctant and do not have time to learn 2 frameworks - could I get away with just adopting Hibernate for the simple things I need to do?

• How to set up precision attribute used by @Collumn annotation ???

  - by Arthur Ronald F D Garcia

  I often use java.lang.Integer as primary key. Here you can see some piece of code @Entity private class Person { private Integer id; @Id @Column(precision=8, nullable=false) public Integer getId() { } } I need to set up its precision attribute value equal to 8. But, when exporting The schema (Oracle), it does not work as expected. AnnotationConfiguration configuration = new AnnotationConfiguration(); configuration .addAnnotatedClass(Person.class) .setProperty(Environment.DIALECT, "org.hibernate.dialect.OracleDialect") .setProperty(Environment.DRIVER, "oracle.jdbc.driver.OracleDriver"); SchemaExport schema = new SchemaExport(configuration); schema.setOutputFile("schema.sql"); schema.create(true, false); schema.sql outputs create table Person (id number(10,0) not null) Always i get 10. Is There some workaround to get 8 instead of 10 ?
