  • Is there an alternative to die?

    - by TJDeatwiler
    Sorry for the dramatic sounding title, just wanted to know if there is a way to prevent all types of PHP commands from executing EXCEPT one. For example, now when I kill a script using die() my pages look half broken because the bottom part of the page's html failed to load since it was being brought in using the include() function. So is there a way to tell PHP "don't allow any more commands to be executed except the include function" ?

  • R programming function without ()

    - by Mark Kennedy
    So, I Have the following very simple map.r file. I'm trying to have the user type "click" in interactive mode and then have the function . Since it's a function, the user has to type "click()" how can I make it so that they only have to the word (w/o parentheses), and then have that function do something with the img. So the user types: mydist("image.pnm") click //And then the function click does what it's supposed to mydist <- function(mapfile) { img <- read.pnm(mapfile) plot(img) } click <- function() { //Prompt user to click on img }

  • GridBagConstraints weightx and weighty values

    - by xdevel2000
    In many books weightx and weighty values are expressed in different ways: some says 0.0 to 1.0 other says 0 to 100 other say until 1000 I'm a lot confused. In the API these variables are double types so I think the first is correct but what does it meaning a value of 0.4 or 0.7? are percentage values, point values? relative of what?

  • Actionscript flex: Converting # colors to uint

    - by Daryl
    I'm working with several components that take color as a uint, but the colors I have are in the format of "#161616". I'm not sure what the relation between the 2 types of colors are or how to go from one to another. It doesn't have to be an actionscript solution. I have only a small number of these colors, so can be done manually too.

  • Can @Inject be made option in JSR 330 (like @Autowire(required=false)?

    - by Eric B.
    Spring's @Autowire can be configured such that Spring will throw an error if no matching autowire candidates are found: @Autowire(required=false) Is there an equivalent JSR-330 annotation? @Inject always fails if there is no matching candidate. Is there any way I can use @Inject but not have the framework fail if no matching types are found? I haven't been able to find any documentation to that extent.

  • How to use another type of EditingControl in a single .NET 3.5 DataGridView column ?

    - by too
    Is this possible to have two (or more) different kinds of cells to be displayed interchangeably in single column of C# .Net 3.5 WinForms DataGridView? I know one column has specified single EditingControl type, yet I think grid is flexible enough to do some tricks, I may think of only: Adding as many invisible columns to grid as required types of cells and on CellBeginEdit somehow exchange current cell with other column's cell Creating custom column and custom cell with possibility of changing EditingControl for single cell Which approach is better, is there any other solution, are there any examples ?

I have tried both of the following with no luck: Directory.GetFiles("C:\\path", "*.mp3|*.jpg", SearchOption.AllDirectories); Directory.GetFiles("C:\\path", "*.mp3;*.jpg", SearchOption.AllDirectories); Is there a way to do this in one call?

  • C++: How to require that one template type is derived from the other

    - by Will
    In a comparison operator: template<class R1, class R2> bool operator==(Manager<R1> m1, Manager<R2> m2) { return m1.internal_field == m2.internal_field; } Is there any way I could enforce that R1 and R2 must have a supertype or subtype relation? That is, I'd like to allow either R1 to be derived from R2, or R2 to be derived from R1, but disallow the comparison if R1 and R2 are unrelated types.

    - by Chris T
    What I'd like is for this class class Car { public function __construct(Engine $engine, Make $make, Model $model) { // stuff } } Get an array that has the types needed to construct this car (Engine, Make, Model) in the order they are needed for the constructor. I'm using this for a Dependency Injection-esque thing I'm making.

  • Blittable Vs. Non-Blittable in IL

    - by Michael Covelli
    I'm trying to make sure that my Managed to Unmanaged calls are optimized. Is there a quick way to see by looking at the IL if any non-blittable types have accidentally gotten into my pinvoke calls? I tried just writing two unmanaged functions in a .dll, one that uses bool (which is non-blittable) and one that uses ints. But I didn't see anything different when looking at the IL to let me know that it was doing something extra to marshal the bool.

  • How to pass Button.Click into a function?

    - by Achilles
    I have a function that adds eventhandlers to control events. Right now I have several overloads that add events to different types of controls: Public Sub AddEventHandler(Button, ButtonEvent) 'adds event handling for Button.Click public Sub AddEventHandler(LinkButton, ButtonEvent)'adds event handling for LinkButton.Click The problem is I want to write a function that is more robust like: Public sub AddEventHandler(Control, EventToHandle, ControlEvent) where EventToHandle is the parameter representing Button.Click or whatever event that Button has associated with it. Any suggestions guys? Thanks!

  • 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?)

How to implement more or less generic routine resulting in a collection of diffs e.g. propertyName , leftValue , rightValue for each such a pair of instances of the same type.
