Demonstrate how to embed a lua interpreter in C code, expose a C-defined function to Lua script, evaluate a Lua script, call a C-defined function from Lua, and call a Lua-defined function from C (the host). In this example, we want the mood to be set by a Lua script. Here is mood.lua: -- Get versi...

Suppose you have multiple threads running. Each thread is doing one task. You want to get notified either on the mainThread OR another thread, when all the task-threads are completed. The simplest solution to such a problem is a DispatchGroup. When using a DispatchGroup, for each request, you ente...

Floating point literals are used to represent signed real numbers. The following suffixes can be used to specify type of a literal: SuffixTypeExamplesnonedouble3.1415926 -3E6f, Ffloat3.1415926f 2.1E-6Fl, Llong double3.1415926L 1E126L In order to use these suffixes, the literal must be a floating p...

Interfaces can seem abstract until you seem them in practice. The IComparable and IComparable<T> are great examples of why interfaces can be helpful to us. Let's say that in a program for a online store, we have a variety of items you can buy. Each item has a name, an ID number, and a price. ...

Suppose you have a parentView into which you want to insert a new subView programmatically (eg. when you want to insert an UIImageView into a UIViewController's view), than you can do it as below. Objective-C [parentView addSubview:subView]; Swift parentView.addSubview(subView) You can also...

q = Queue.new q << "any object including another queue" # or q.push :data There is no high water mark, queues can infinitely grow. #push never blocks

syncer = Queue.new a = Thread.new do syncer.pop puts "this happens at end" end b = Thread.new do puts "this happens first" STDOUT.flush syncer << :ok end [a, b].map(&:join)

q = Queue.new q << 1 q << 2 a = Array.new a << q.pop until q.empty? Or a one liner: [].tap { |array| array < queue.pop until queue.empty? }

textBox.KeyPress += (sender, e) => e.Handled = !char.IsControl(e.KeyChar) && !char.IsDigit(e.KeyChar); This will only permit the use of digits and control characters in the TextBox, other combinations are possible using the same approach of setting the Handle property to true to block ...

From MSDN Use the CInt function to provide conversions from any other data type to an Integer subtype. For example, CInt forces integer arithmetic when currency, single-precision, or double-precision arithmetic would normally occur. Assuming that you have 1 button and 2 textbox. If you type...

DATA: <TABLE NAME> TYPE <SORTED|STANDARD|HASHED> TABLE OF <TYPE NAME> WITH <UNIQUE|NON-UNIQUE> KEY <FIELDS FOR KEY>. Standard Table This table has all of the entries stored in a linear fashion and records are accessed in a linear way. For large table sizes, ...

To print a test field (TestField) from a test feature class (TestFC) in a test file geodatabase (Test.gdb) located in a temporary folder (C:\Temp): with arcpy.da.SearchCursor(r"C:\Temp\Test.gdb\TestFC",["TestField"]) as cursor: for row in cursor: print row[0]

If an arithmetic operation that yields a floating point type produces a value that is not in the range of representable values of the result type, the behavior is undefined according to the C++ standard, but may be defined by other standards the machine might conform to, such as IEEE 754. float x =...

When either a signed or unsigned integer is converted to a signed integer type, and its value is not representable in the destination type, the value produced is implementation-defined. Example: // Suppose that on this implementation, the range of signed char is -128 to +127 and // the range of un...

Emacs uses the terms point, mark, and region to provide more precision about the selected text and position of the cursor. By understanding these terms, it'll help you understand and use other operations and functions. The point is the place in a buffer where editing (i.e. insertion) is currently t...

The Scala Collections framework, according to its authors, is designed to be easy to use, concise, safe, fast, and universal. The framework is made up of Scala traits that are designed to be building blocks for creating collections. For more information on these building blocks, read the official S...

Setters and Getters allow for an object to contain private variables which can be accessed and changed with restrictions. For example, public class Person { private String name; public String getName() { return name; } public void setName(String name) { i...

Create a new Console Application Add the NuGet package Microsoft.CodeAnalysis Import the namespaces Microsoft.CodeAnalysis.MSBuild, System.Linq and Microsoft.CodeAnalysis.CSharp.Syntax Write the following example code in the Main method: // Declaring a variable with the current project file ...

The System.String.Join method allows to concatenate all elements in a string array, using a specified separator between each element: string[] words = {"One", "Two", "Three", "Four"}; string singleString = String.Join(",", words); // singleString =...

If all you need is to wrap the value into a promise, you don't need to use the long syntax like here: //OVERLY VERBOSE var defer; defer = $q.defer(); defer.resolve(['one', 'two']); return defer.promise; In this case you can just write: //BETTER return $q.when(['one', 'two']); $q.when ...
