• Wrap Sub as Function for use in Lambda

  - by Luhmann

  I have a problem with VB and Moq. I need to call a verify on a Sub. Like so: logger.Verify(Function(x) x.Log, Times.AtLeastOnce) And my logger looks like this: Public Interface ILogger Sub Log() End Interface But with VB this is not possible, because the Log method is a Sub, and thereby does not produce a value. I don't want to change the method to be a function. Whats the cleanest way of working around this limitation and is there any way to wrap the Sub as a Function like the below? logger.Verify(Function(x) ToFunc(AddressOf x.Log)) I have tried this, but i get: Lambda Parameter not in scope

• A way to share the return value of fsockopen() between multiple pages?

  - by Chilln

  Hey, im using a connection to a server in my php script, opened with fsockopen() and i want it to share between different pages so i serialized it and saved it in a session variable but it seems that that ia a bad idea because when i do this nothing happens... Not even an error. The problem is that this connection requires a handshake so i cant reconnect everytime Another question, whats the timeout of fsockopen or does the connection stay alive if the. original php script which called it is closed?

• Can a plain servlet be configured to as a seam component?

  - by stacker

  I created a plain servlet within a seam-gen (2.1.2) application, now I would like to use injection. Thus I annotated it with @Name and it's recognized as component: INFO [Component] Component: ConfigReport, scope: EVENT, type: JAVA_BEAN, class: com.mycompany.servlet.ConfigReport Unfortunatly the injection of the logger doesn't work NullPointerException in init() import org.jboss.seam.annotations.Logger; import org.jboss.seam.annotations.Name; import org.jboss.seam.log.Log; @Name("ConfigReport") public class ConfigReport extends HttpServlet { @Logger private Log log; public void init(ServletConfig config) throws ServletException { log.info( "BOOM" ); } } Is my approach abusive? What would be the alternatives (the client sending requests to the servlet is curl, not a browser)?

• Programming Exercises for Learning Purposes?

  - by cam

  Are there any programming exercises that apply to any language? Before I got my first job, I thought I knew C# pretty well, then I was thrown right into the deep end, and now I know I have a good command over the language. I would like to apply the same method to other languages, but unfortunately, I'm sort of stuck with C# at work. Ideally, something similar (but broader in scope) to Project Euler is ideal. Project Euler helped me learn a ton of C++/F#, some math, algorithms, handling bignums, etc. I'm looking for something like this.

• Workflow for reading and writing files

  - by AIR_PhillipSenn

  In Workflow for reading and writing files the authors use these two lines of code: var file = air.File.documentsDirectory; file = file.resolvePath("AIR Test/testFile.txt"); But I think that it's using one variable for two different meanings, isn't it? Wouldn't it be better to write them as: var myDocumentsDirectory = air.File.documentsDirectory; var myTestFile = myDocumentsDirectory.resolvePath("AIR Test/testFile.txt");

• Function of: if(/(file|http).*/.test(url)) { }

  - by WmasterJ

  I am wondering what this technique is called and what it does. It seems to be validating some regular expression on the variable url. I am customizing another persons code: var url = document.getElementById("editorURL").value; if(/(file|http).*/.test(url)) { } Maybe someone has a link to an article that explains this a bit more in-depth?

• Convert user input into ToString() method inside FlowDocument in Workflow 4.0

  - by Jon Ownbey

  I have a Workflow 4.0 app that generates emails. In a dialog for creating the email body the user needs to be able to input some string value representing an existing wf instance variable to be inserted as a string at runtime. So they input something like: Email body text including <. (say ExistingVariable is an int or something like that) Any helpful hints for how to convert this text with a ToString() at runtime?

• Answered: Selecting even table rows from a table element

  - by mvrak

  The issue I am having is: How do I go from a variable pointing at an element to using CSS selectors? I want to make this work: function highlight(table) {$(table " > :even").toggleClass('highlight');} where table is a reference to a table element. I don't want answers that tell me to use $('#table') because that defeats the point of the generality I am trying to make. Thanks

• Editing code in Visual Studio 2008 in debug mode

  - by user279521

  I am curious to know if there is a way to edit code in VS 2008 right when it has hit a breakpoint and I am walking thru the code... can I modify the code (such as the value in a variable or if my stepthrough line is about to hit an if statement ... can I modify the if statement....etc)? So far, I have to stop running VS, modify the code, then hit F5 and wait till the breakpoint is hit again.

• Do you know of some performances test of the different ways to get thread local storage in C++?

  - by Vicente Botet Escriba

  I'm doing a library that makes extensive use of a thread local variable. Can you point to some benchmarks that test the performances of the different ways to get thread local variables in C++: C++0x thread_local variables compiler extension (Gcc __thread, ...) boost::threads_specific_ptr pthread Windows ... Does C++0x thread_local performs much better on the compilers providing it?

• Scala puts precedence on implicit conversion over "natural" operations... Why? Is this a bug? Or am

  - by Alex R

  This simple test, of course, works as expected: scala var b = 2 b: Int = 2 scala b += 1 scala b res3: Int = 3 Now I bring this into scope: class A(var x: Int) { def +=(y:Int) { this.x += y } } implicit def int2A(i:Int) : A = new A(i) I'm defining a new class and a += operation on it. I never expected this would affect the way my regular Ints behave. But it does: scala var b:Int = 0 b: Int = 0 scala b += 1 scala b res29: Int = 0 scala b += 2 scala b res31: Int = 0 Scala seems to prefer the implicit conversion over the natural += that is already defined to Ints. That leads to several questions... Why? Is this a bug? Is it by design? Is there a work-around (other than not using "+=")? Thanks

• Is it alright to call len() in a loop's conditional statement?

  - by DormoTheNord

  In C, it is considered bad practice to call strlen like this: for ( i = 0; strlen ( str ) != foo; i++ ) { // stuff } The reason, of course, is that it is inefficient since it "counts" the characters in a string multiple times. However, in Python, I see code like this quite often: for i in range ( 0, len ( list ) ): # stuff Is this bad practice? Should I store the result of len() in a variable and use that?
