This is similar to: DLR return type You do need to match the return type specified by the ReturnType property. For all of the standard binaries this is fixed to object for almost everything or void (for the deletion operations). If you know you’re making a void call I’d suggest wrapping it in: Expression.Block( call, … Read more
If a program is compiled you can’t change it anymore. This is wrong. In image-based systems, like Lisp (Clojure can be seen as a Lisp dialect) and Smalltalk, you can change the compiled environment. Development in such a language typically means working on a running system, adding and changing function definitions, macro definitions, parameters etc. … Read more
Static Typing Static typing means that types are known and checked for correctness before running your program. This is often done by the language’s compiler. For example, the following Java method would cause a compile-error, before you run your program: public void foo() { int x = 5; boolean b = x; } Dynamic Typing … Read more
I favor this minimal code change: Just add these two lines after addSubview and before grabbing the height of the frame … [scrollView1 addSubview: myTextView]; [myTextView sizeToFit]; //added [myTextView layoutIfNeeded]; //added CGRect frame = myTextView.frame; … This is tested backwards compatible with iOS 6. NOTE that it shrink-wraps the width. If you’re just interested in … Read more
I found solution 🙂 It is very very easy but i could’t see at first 🙂 only like that : <mat-cell *matCellDef=”let element “> {{element[disCol]}} </mat-cell> I must use {{element[disCol]}} only in HTML. Now , everything is ok:)
I believe the problem is that the anonymous type is generated as internal, so the binder doesn’t really “know” about it as such. Try using ExpandoObject instead: public static dynamic GetValues() { dynamic expando = new ExpandoObject(); expando.Name = “Michael”; expando.Age = 20; return expando; } I know that’s somewhat ugly, but it’s the best … Read more
Anonymous types having internal properties is a poor .NET framework design decision, in my opinion. Here is a quick and nice extension to fix this problem i.e. by converting the anonymous object into an ExpandoObject right away. public static ExpandoObject ToExpando(this object anonymousObject) { IDictionary<string, object> anonymousDictionary = new RouteValueDictionary(anonymousObject); IDictionary<string, object> expando = new … Read more
The instanceof-operator is called is in Dart. The spec isn’t exactly friendly to a casual reader, so the best description right now seems to be http://www.dartlang.org/articles/optional-types/. Here’s an example: class Foo { } main() { var foo = new Foo(); if (foo is Foo) { print(“it’s a foo!”); } }
