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...
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;
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...
You can group related assertions in deftest unit tests within a context using the testing macro: (deftest add-nums (testing "Positive cases" (is (= 2 (+ 1 1))) (is (= 4 (+ 2 2)))) (testing "Negative cases" (is (= -1 (+ 2 -3))) (is (= -4 (+ 8 -12))))) ...
deftest is a macro for defining a unit test, similar to unit tests in other languages. You can create a test as follows: (deftest add-nums (is (= 2 (+ 1 1))) (is (= 3 (+ 1 2)))) Here we are defining a test called add-nums, which tests the + function. The test has two assertions. You can ...
Input table data (People table) IdNameAge1John232Jane31 Query SELECT Id, Name, Age FROM People FOR JSON PATH Result [ {"Id":1,"Name":"John","Age":23}, {"Id":2,"Name":"Jane","Age":31} ]
(let [x true y true z true] (match [x y z] [_ false true] 1 [false true _ ] 2 [_ _ false] 3 [_ _ true] 4)) ;=> 4
(let [v [1 2 3]] (match [v] [[1 1 1]] :a0 [[1 _ 1]] :a1 [[1 2 _]] :a2)) ;; _ is used for wildcard matching ;=> :a2
(let [x {:a 1 :b 1}] (match [x] [{:a _ :b 2}] :a0 [{:a 1 :b _}] :a1 [{:x 3 :y _ :z 4}] :a2)) ;=> :a1
(match [['asymbol]] [['asymbol]] :success) ;=> :success
In addition to a failure/success return value, some API calls also set the last error on failure (e.g. CreateWindow). The documentation usually contains the following standard wording for this case: If the function succeeds, the return value is <API-specific success value>. If the function...
Some API calls can succeed or fail in more than one way. The APIs commonly return additional information for both successful invocations as well as errors (e.g. CreateMutex). if ( CreateMutexW( NULL, TRUE, L"Global\\MyNamedMutex" ) == NULL ) { // Failure: get additional information. ...
The . operator in Rust comes with a lot of magic! When you use ., the compiler will insert as many *s (dereferencing operations) necessary to find the method down the deref "tree". As this happens at compile time, there is no runtime cost of finding the method. let mut name: String = &quo...
In Drupal 7 and lower, your configuration is probably stored using the Features module. To update a feature with changes from the databases use this command: drush features-update [feature-name] // e.g. drush features-update content_type_news You can also use this shorthand: drush fu [feature-n...
function createNewFolderInGoogleDrive(folderName) { return DriveApp.createFolder(folderName); } Use function createNewFolderInGoogleDrive to create folder named Test folder in a Google Drive root: var newFolder = createNewFolderInGoogleDrive('Test folder'); newFolder has Class Folder typ...
