Take a look at my answer to this question. Note how you can use echoargs.exe to diagnose these sort of problems. Most likely the fix would be to quote the parameter e.g.: java -jar “-Duser.language=en” any.jar You can test that using echoargs (from PowerShell Community Extensions): echoargs -jar “-Duser.language=en” any.jar Arg 0 is <-jar> Arg … Read more
Synthesized ivars (the ability to not manually declare ivars) are a feature of the new Objective-C runtime, which still isn’t being used on all systems. For 32-bit Macs (and, until recently, the iPhone simulator), you have to manually declare ivars. If you’re only targeting systems with the new runtime, there’s no reason to manually declare … Read more
var idPost=document.getElementById(“status”).innerHTML; The ‘status’ element does not exist in your webpage. So document.getElementById(“status”) return null. While you can not use innerHTML property of NULL. You should add a condition like this: if(document.getElementById(“status”) != null){ var idPost=document.getElementById(“status”).innerHTML; }
I do not suggest doing this on your application but for testing purpose it may be usefull… Assuming you have: public class MyClass { public int MyNumber {get;} } You could do this if its for test purpose, I would not suggest to use this in your runtime code: var field = typeof(MyClass).GetField(“<MyNumber>k__BackingField”, BindingFlags.Instance | … Read more
Statics are unique to the application domain, all users of that application domain will share the same value for each static property. When you see the word static, think “there will only be one instance of this.” How long that instance lasts is a separate question, but the short answer is that it is variable. … Read more
In the current version of Chrome (Sept 2017), I’m limited to around 8.3 million keys. Try pasting this in your browser console: let obj = {}; let keyCount = 0; while(1) { obj[Math.random()] = Math.random(); if(++keyCount % 10000 === 0) console.log(keyCount); } I get an identical limit in Node.js: node –max-old-space-size=20000 -e “let obj = … Read more
I only ever expose public fields when they’re (static) constants – and even then I’d usually use a property. By “constant” I mean any readonly, immutable value, not just one which may be expressed as a “const” in C#. Even readonly instance variables (like Result and Message) should be encapsulated in a property in my … Read more
The closest you can get are attached properties. Basically, another class defines a known property (i.e. MyProperty), which can be set on other elements. An example would be the Canvas.Left property, which is used by the Canvas to position a child element. But any class can define an attached property. Attached properties are the key … Read more
Mojo’s Build-Helper Maven Plugin can help you out here. There are a number of goals that can be used to help transform properties. There is build-helper:regex-property build-helper:parse-version build-helper:released-version Probably regex-property is the one you want, but if your version numbers conform to the “standards” the other two might save you. To use the regex-property goal … Read more
They are almost exactly equivalent except that the first method (using an object initializer) only works in C# 3.0 and newer. Any performance difference is only minor and not worth worrying about. They produce almost identical IL code. The first gives this: .method private hidebysig instance void ObjectInitializer() cil managed { .maxstack 2 .locals init … Read more
