• Cancel the calculation if input-mismatch was found

  - by Lert Pianapitham

  Hallo everybody, i have programmed a sub procedure, that will be called in the main procedure (called by event of mainForm), to valid the inputs before the main calculation. now i'm searching for a method, how can i cancel the calculation and refocus the mainForm if some inputs mismatch. i think, it's unnecessary to use the Try-Catch statment to trap the error from calculation because i know what is its source and it should be prevented due to the code preformance. Has someone an idea to due with this? best regards Lert Pianapitham

• Where does code within Script tags go in the resulting AS class?

  - by Hanno Fietz

  I was wondering what happens to the code contained in an <mx:Script> tag. If I define a function tehre, it just becomes a member function of the generated class. But I noticed that it seems OK for the compiler if I just write some (static) method calls there (specifically, I call Font.registerFont()). I feel kind of guilty for doing this, because I have no idea what's really happening and when the code gets executed.

• Create a custom button

  - by Beppi Menozzi

  Sorry if this is too basic. I created a new class that extends Button: public class MyButton extends Button { private Context ctx; public MyButton(Context context) { super(context); ctx = context; } private void click() { // DO WHAT I NEED (FOR EXAMPLE CHANGE BACKGROUND) } } How can make it possible that, when I setOnClickListener() from another class where I instantiated this object, the click() method is called automatically? Thanks.

• What is the .NET equivalent of PHP var_dump?

  - by George Mauer

  I remember seeing a while ago that there is some method in maybe the Reflection namespace that would recursively run ToString() on all of an object's properties and format it nicely for display. Yes, I know everything I could want will be accessible through the debugger, but I'm wondering if anyone knows that command?

But when the client passes in "hello", it's to_s value is "hello". class UsersApiController < ApiController web_service_api UserApi def create_or_update(arg1) Rails.logger.info arg1.to_s # Displays "#<SOAP::Mapping::Object:0x3a89c08>" if arg1 is an empty string end end

Thanks

• Entity Framework 4.0 GetChanges() equivalent

  - by Jonathan

  Hi In LINQ to SQL, you can override SubmitChanges and use the method this.GetChangeSet() to get all the inserts, updates and deletes so that you can make last minute changes before it is committed to the database. Can this be done in EF 4.0? I see there is a override for SaveChanges but I need to know the equivalent for GetChangeSet()

• Why closed contours are guaranteed here?

  - by user198729

  Quoted from here: BW = edge(I,'zerocross',thresh,h) specifies the zero-cross method, using the filter h. thresh is the sensitivity threshold; if the argument is empty ([]), edge chooses the sensitivity threshold automatically. If you specify a threshold of 0, the output image has closed contours, because it includes all the zero crossings in the input image. I don't understand it,can someone elaborate?

• Why Java does not allow overriding equals(Object) in an Enum?

  - by Ashwin Prabhu

  @Override public boolean equals( Object otherObject ) is not allowed in Java for an Enum, since the method equals(Object x) is defined as final in Enum. Why is this so? I cannot thing of any use case which would require overriding equals(Object) for Enum. I'm just curious to know the reasoning behind this behavior.

• Navigate HTML Source while performing WatiN tests

  - by youwhut

  I am performing actions on the page during WatiN tests. What is the neatest method for asserting certain elements are where they should be by evaluating the HTML source? I am scraping the source but looking for a clean way to navigate the tags pulled back. UPDATE: Right now I am thinking about grabbing certain elements within HTML source using regular expressions and then analysing that to see if other elements exist within. Other thoughts appreciated.

• When is it necessary to override Equals() in a .NET class?

  - by Alex Angas

  .NET contains its own equality comparison functionality, however I don't really understand how it works. If the desired Equals() and == behaviour is to verify that every field of an object is equal to every field of another object, is it necessary to override Equals() with a method that does this explicitly?

• Is it a bad programming practice to have "Public" members inside an "Internal" class?

  - by Amby

  I mean, won;t it be more specific and appropriate if i "only" keep "protected","internal" and "private" members (field,method,property,event) in a class which is declared as "internal" ? I have seen this practice ( having "public" members in an "internal" class) in various code so just wanted to know is it a bad practice or does it has some benefit or advantage. [Only concerned about C#] Thanks for your interest.

• Does Core Data take appropriate action automatically when there's a Low Memory Warning?

  - by dontWatchMyProfile

  Does it turn some managed objects into faults when there's a Low Memory Warning? Or must we do that manually by calling the -refreshObjects:mergeChanges: method which puts the affected managed objects on diet quickly? And...would that actually hurt? What if these objects are currently used by an NSFetchedResultsController to show up on a table view?

• What are the standard practices for throwing JavasScript Exceptions?

  - by T.R.

  w3schools says that exceptions can be strings, integers, booleans, or objects, but the example given doesn't strike me as good practice, since exception type checking is done through string comparison. Is this the preferred method of exception handling in JavaScript? Are there built-in exception types (like NullPointerException)? (if so, what are they, what kind of inheritance do they use, and are they preferred over other options?)
