When casting floats to integers, overflow causes undefined behavior. From the C99 spec, section 6.3.1.4 Real floating and integer: When a finite value of real floating type is converted to an integer type other than _Bool, the fractional part is discarded (i.e., the value is truncated toward zero). If the value of the integral part … Read more
The way to add custom config (if you require more than just simple types) is to use a ConfigurationSection, within that for the schema you defined you need a ConfigurationElementCollection (set as default collection with no name), which contains a ConfigurationElement, as follows: public class UserElement : ConfigurationElement { [ConfigurationProperty( “firstName”, IsRequired = true )] … Read more
As stated by both BFree and James, there is no difference in Start\Stop versus Enabled with regards to functionality. However, the decision on which to use should be based on context and your own coding style guidelines. It depends on how you want a reader of your code to interpret what you’ve written. For example, … Read more
I think the exact terminology for what you need is “template covariance”, meaning that if B inherits from A, then somehow T<B> inherits from T<A>. This is not the case in C++, nor it is with Java and C# generics*. There is a good reason to avoid template covariance: this will simply remove all type … Read more
This is still the way to do it. Unfortunately you cannot declare or define functions within a namespace like you would do with a class: you need to actually wrap them in a namespace block.
One good method is the Miller-Rabin test. It should be noted however, that this is only a probabilistic test.
Try this: public delegate void MoveDelegate(object o); public static MoveDelegate MoveMethod; So the method-variable can be defined static. The keyword static has no meaning for the delegate definition, just like enum or const definitions. An example of how to assign the static method-field: public class A { public delegate void MoveDelegate(object o); public static MoveDelegate … Read more
In most cases when I’ve had to have two things reference each other, I’ve created an interface to remove the circular reference. For example: BEFORE public class Foo { Bar myBar; } public class Bar { Foo myFoo; } Dependency graph: Foo Bar ^ ^ | | Bar Foo Foo depends on Bar, but Bar … Read more
I think this should do the trick: // Split the url to url + query string var fullUrl = Request.UrlReferrer.ToString(); var questionMarkIndex = fullUrl.IndexOf(‘?’); string queryString = null; string url = fullUrl; if (questionMarkIndex != -1) // There is a QueryString { url = fullUrl.Substring(0, questionMarkIndex); queryString = fullUrl.Substring(questionMarkIndex + 1); } // Arranges var … Read more
I’ve just converted my VB.NET class to C# to detect mime types. They will be identified by a mix of sniffing the first 256 Bytes of a file(urlmon.dll – f.e. used by internet explorer) and a set of known types. You can also use it to check if the file is what it pretends to … Read more
