• Debugging MEF running in ASP.NET

  - by Jeffrey Lott

  I'm trying to do a proof of concept app for my work using ASP.NET WebForms and the Managed Extensibility Framework. I've got things up and running(ish), but I can't seem to figure out how to attach the instance of Visual Studio that has the MEF code in it to the instance of Visual Studio that is running the Web App. How can I attach my MEF code to the running process so that it hits my breakpoints?

  My understanding is serialVersionUID is applicable only to classes, because we can create an object only to classes and the concept of serialVersionUID is for object serialization and deserialization.

• iphone: unrecognized selector sent to instance

  - by eshalev

  I am new to objective C, So maybe there is some basic thing that I am missing about selectors. I would like to understand the basic concept behind this error as I have not found an general error reference. I am getting this error when using: [CloseButton addTarget:PageContents action:@selector(CloseButtonPressed) forControlEvents:UIControlEventTouchUpInside]; and then later: - (void)CloseButtonPressed:(id)sender{ UIAlertView *someError = [[UIAlertView alloc] initWithTitle: @"Comment" message: @"hello" delegate: self cancelButtonTitle: @"Ok" otherButtonTitles: nil]; [someError show]; [someError release]; }

• What are the barriers to understanding pointers and what can be done to overcome them?

  - by David McGraw

  Why are pointers such a leading factor of confusion for many new, and even old, college level students in the C/C++ language? Are there any tools or thought processes that helped you understand how pointers work at the variable, function, and beyond level? What are some good practice things that can be done to bring somebody to the level of, "Ah-hah, I got it," without getting them bogged down in the overall concept? Basically, drill like scenarios.

• Example of forum in Object Oriented PHP

  - by Martin Trigaux

  Hello, I'm trying to learn to use PHP with an object oriented scheme. I think I understand the concept but I need real example, a forum exactly (the closest to what I want to do). I know PhpBB but it's maybe too complicated to fully understand it so I'm looking for something simpler but still in object oriented. Do you know any ? Thank you

• Is there an efficient way to call a Grails template from a string loaded from db?

  - by Kimble

  I store user editable articles in a database. Users can insert some simple widgets into the articles (graphs and so on). So far I've implemented this as a proof of concept by letting the user insert graphs like [graph-1] and than do a string search and replace. I was wondering whether there are more efficient ways of calling templates from a string? Maybe involving Sitemesh?

• Why increased pipeline depth does not always mean increased throughput?

  - by worlds-apart89

  This is perhaps more of a discussion question, but I thought stackoverflow could be the right place to ask it. I am studying the concept of instruction pipelining. I have been taught that a pipeline's instruction throughput is increased once the number of pipeline stages is increased, but in some cases, throughput might not change. Under what conditions, does this happen? I am thinking stalling and branching could be the answer to the question, but I wonder if I am missing something crucial.

• Understanding max JVM heap size

  - by Marcus

  I've read the max heap size on 32bit Windows is ~1.5GB which is due to the fact that the JVM requires contiguous memory. Can someone explain the concept of "contiguous memory" and why you only have max 1.5GB on Windows? Secondly, what then is the max heap size on 64 bit Windows and why is this different than what's available on 32 bit?

• What do you call this functional language feature?

  - by Jimmy

  ok, embarrassing enough, I posted code that I need explained. Specifically, it first chains absolute value and subtraction together, then tacks on a sort, all the while not having to mention parameters and arguments at all, because of the presense of "adverbs" that can join these functions "verbs" What (non-APL-type) languages support this kind of no-arguments function composition (I have the vague idea it ties in strongly to the concepts of monad/dyad and rank, but its hard to get a particularly easy-to-understand picture just from reading Wikipedia) and what do I call this concept?

• How do I dynamically reference incremented properties in C#?

  - by Jeff Blankenburg

  I have properties called reel1, reel2, reel3, and reel4. How can I dynamically reference these properties by just passing an integer (1-4) to my method? Specifically, I am looking for how to get an object reference without knowing the name of the object. In Javascript, I would do: temp = eval("reel" + tempInt); and temp would be equal to reel1, the object. Can't seem to figure this simple concept out in C#.

• Why do new ASP.NET books still refer to "Classic ASP?"

  - by Jason

  I have read several ASP.NET 3.5 and 4.0 books that begin explaining a concept with something like "in classic ASP it would have been done like this." Why do ASP.NET 4.0 books still refer to classic ASP? Are there really that many developers jumping from Classic ASP directly to ASP.NET 4.0 or is it just force of habit?

• Development Environment for Testing MySQL Replication

  - by Dave Morris

  Is there an easy way to setup an environment on one machine (or a VM) with MySQL replication? I would like to put together a proof of concept of MySQL replication with one Master write instance and two slave instances for reads. I can see doing it across 2 or 3 VMs running on my computer, but that would really bog down my system. I'd rather have everything running on the same VM. What's the best way to proof out scalability solutions like this in a local dev environment? Thanks for your help, Dave

• Can anyone explain the difference between closure and anonymous functions?

  - by Stick it to THE MAN

  I am relatively new to Javascript. I understand the concept of anonymous functions - but closures seem less clear. The similarity between the two (in my mind atleast), is confusing. Could someone explain the difference? (preferrably, with some code snippet, to illustrate the points clearer).

• Which programming languages that can generate self contained windows .exes?

  - by Zubair

  I want to make an easy to deploy Windows application and was was wondering which programming systems can create totally self contained Windows .exe files? As a plus, if the same can be done with MacOSX and Linux from the same source this would be a bonus. I took a look at Realbasic but they have since abandoned the single .exe concept.

• Is it bad to use a model directly from a view in codeigniter?

  - by jason

  I know normally the data is passed thru to the view with the controller. however, currently in my view I load my model ($this-load-model('Db_model');) so i can use it in a loop to retrieve a users profile picture path from a array of IDs that is passed from controller. Will loading the db model in the view to accomplish this make my site more vulnerable or bad form? To me it seems to be outside of MVC concept but its working atm. thanks
