When custom options are merged, they use the default strategy, which simply overwrites the existing value. If you want a custom option to be merged using custom logic, you need to attach a function to Vue.config.optionMergeStrategies: Vue.config.optionMergeStrategies.myOption = function (toVal, fro...

When a mixin and the component itself contain overlapping options, they will be “merged” using appropriate strategies. For example, hook functions with the same name are merged into an array so that all of them will be called. In addition, mixin hooks will be called before the component’s own hooks:...

Let's say you have a service the same as the one defined in the "First service and host" example. To create a client, define the client configuration section in the system.serviceModel section of your client configuration file. <system.serviceModel> <services> <cli...

RoboGuice is a framework that brings the simplicity and ease of Dependency Injection to Android, using Google's own Guice library. @ContentView(R.layout.main) class RoboWay extends RoboActivity { @InjectView(R.id.name) TextView name; @InjectView(R.id.thumbnail) Image...

Add the following pom to the dependencies section of your gradle build file : project.dependencies { compile 'org.roboguice:roboguice:3.+' provided 'org.roboguice:roboblender:3.+' }

The @ContentView annotation can be used to further alleviate development of activities and replace the setContentView statement : @ContentView(R.layout.myactivity_layout) public class MyActivity extends RoboActivity { @InjectView(R.id.text1) TextView textView; @Override protected ...

You can inject any type of resource, Strings, Animations, Drawables, etc. To inject your first resource into an activity, you'll need to: Inherit from RoboActivity Annotate your resources with @InjectResource Example @InjectResource(R.string.app_name) String name; @InjectResource(R.drawa...

You can inject any view using the @InjectView annotation: You'll need to: Inherit from RoboActivity Set your content view Annotate your views with @InjectView Example @InjectView(R.id.textView1) TextView textView1; @InjectView(R.id.textView2) TextView textView2; @InjectView(R.id.imag...

The UIAlertController available since iOS8 allows you to use the same alert object for either Action sheets or more classic alerts. The only difference is the UIAlertControllerStyle passed as a parameter when creating. This line changes from an AlertView to an ActionSheet, compared to some other ex...

It was common practice to use NSRunLoop to show modal UIAlertView to block code execution until user input is processed in iOS; until Apple released the iOS7, it broke few existing apps. Fortunately, there is a better way of implementing it with C#’s async/await. Here’s the new code taking advantag...

User input Imagine you want a user to enter a number via input. You want to ensure that the input is a number. You can use try/except for this: Python 3.x3.0 while True: try: nb = int(input('Enter a number: ')) break except ValueError: print('This is not a num...

To change the appearance of the keyboard, the following types can be set individually on every UITextFields property: keyboardType typedef NS_ENUM(NSInteger, UIKeyboardType) { UIKeyboardTypeDefault, // Default type for the current input method. UIKeyboardTypeASCIICapable, ...

To create a variable: variableType variableName; For example: int a; To create a variable and initialize it: variableType variableName = initialValue; For example: int a = 2;

If you have a variable declared before, you can assign some value to it: For example: int a; // declared previously a = 2; Or change the value: int a = 3; // initalized previously a = 2;

char : signed 1-byte character value byte : unsigned 8-bit integer int : signed 16-bit (on ATMEGA based boards) or 32-bit (on Arduino Due) integer unsigned int : unsigned 16-bit (on ATMEGA based boards) or 32-bit (on Arduino Due) integer long : signed 32-bit integer unsigned long : unsigned 3...

DECLARE @Employees TABLE ( EmployeeID INT NOT NULL PRIMARY KEY, FirstName NVARCHAR(50) NOT NULL, LastName NVARCHAR(50) NOT NULL, ManagerID INT NULL ) When you create a normal table, you use CREATE TABLE Name (Columns) syntax. When creating a table variable, you use DECLARE @...

DECLARE @VariableName INT SET @VariableName = 1 PRINT @VariableName 1 Using SET, you can only update one variable at a time.

Using SELECT, you can update multiple variables at once. DECLARE @Variable1 INT, @Variable2 VARCHAR(10) SELECT @Variable1 = 1, @Variable2 = 'Hello' PRINT @Variable1 PRINT @Variable2 1 Hello When using SELECT to update a variable from a table column, if there are multiple values, it wi...

DECLARE @Var1 INT = 5, @Var2 NVARCHAR(50) = N'Hello World', @Var3 DATETIME = GETDATE()

This is an example of what a simple Arduino sketch looks like after being imported into Atmel Studio. Atmel Studio added the auto generated sections at the top. The rest is identical to the original Arduino code. If you expand the ArduinoCore project that was created and look in the src -> cor...
