What type-conversions are happening?
#include "stdio.h" int main() { int x = -13701; unsigned int y = 3; signed short z = x / y; printf("z = %d\n", z); return 0; } I would expect the answer to be -4567. I am getting "z = 17278". Why does a promotion of these numbers result in 17278? I executed this in Code Pad. ...
Type conversion with Generic List and Interfaces in C# - Looking for an elegant solution.
Take the following example (created purely to demonstrate the point). What I am trying to do is isolate one part of the system from another and only want to expose a specific subset of the functionality externally from the assembly while internally working against the full objects methods. This code compiles, but I get an invalid cast ...
User-defined type conversions in ActionScript?
Is there any way for me to define implicit or explicit type conversions in ActionScript? For instance, I want to define a conversion such that Array can cast into MyClass implicitly. If not, an explicit cast would be useful. I know I can always pass it into my constructor, but I am dealing with semantics here, and I am most interested...
Java type conversion where types are not known until runtime
I'm trying to write a data access layer for an AJAX web project. This DAL has to convert data coming in via an AJAX servlet to objects that can be passed to a PreparedStatement for execution. Data in the AJAX servlet, retrieved by using HttpServletRequest.getParameter(...), come in as strings. In each data class, I have a known set of ...

What's the reason of using implicit/explicit convertions instead of constructors?
An example would be: XNamespace ns = "my namespace" Why not?: XNamespace ns = new XNamespace ( "my namespace" ) What's the idea behind using implicit/explicit convertions instead of constructors? Convenience? Is there a guideline for this? ...
extending Convert.ChangeType to produce user-defined types on request
Given the class: public class Foo { public string Name { get; set; } } Is it possible to have a Foo instance created from a string through Convert.ChangeType: Type type = typeof(Foo); object value = "one"; value = System.Convert.ChangeType(value, type); This is how a 3rd party API is attempting to rebuild objects. Someone men...
Change only parts of a type in a C++ template
Purpose and craziness aside, is there a way to achieve this in C++? template <typename P> void Q void_cast(P Q *p) const { return static_cast<P Q *>(p); } I'm effectively trying to cast a pointer to a void pointer type whilst keeping any const, restrict and other qualifiers (denoted by Q). I was under the impression there was stu...
Problems with calculations and conversions in Visual Basic Form

How to do a static cast in C#?
Given a couple types like this: interface I {} class C : I {} How can I do a static type cast? By this I mean: how can I change its type in a way that gets checked at compile time? In C++ you can do static_cast<I*>(c). In C# the best I can do is create a temporary variable of the alternate type and try to assign it: var c = new C();...
Where do you put the parentheses to concisely convert a casted object to a primitive type without auto-unboxing?
With autounboxing, this statement will automatically work: int myPrimitive = (Integer) doIt(); But if I want to explicitly convert from an Integer to an int here in a single line, where do I have to put the parentheses? ...

How to perform unsigned to signed conversion in Java?
Say I read these bytes: "6F D4 06 40" from an input device. The number is a longitude reading in MilliArcSeconds format. The top bit (0x80000000) is basically always zero and is ignored for this question. I can easily convert the bytes to an unsigned integer: 1876166208 But how do I convert that unsigned value into its final form of 3...
What is guaranteed about the size of a function pointer?
In C, I need to know the size of a struct, which has function pointers in it. Can I be guaranteed that on all platforms and architectures: the size of a void* is the same size as a function pointer? the size of the function pointer does not differ due to its return type? the size of the function pointer does not differ due to its param...
