To save a reference to a cell in a variable, you must use the Set syntax, for example: Dim R as Range Set R = ActiveSheet.Cells(3, 1) later... R.Font.Color = RGB(255, 0, 0) Why is the Set keyword required? Set tells Visual Basic that the value on the right hand side of the = is meant to be ...

os.path.abspath(os.path.join(PATH_TO_GET_THE_PARENT, os.pardir))

context.globalAlpha=0.50 You can change the opacity of new drawings by setting the globalAlpha to a value between 0.00 (fully transparent) and 1.00 (fully opaque). The default globalAlpha is 1.00 (fully opaque). Existing drawings are not affected by globalAlpha. // draw an opaque rectangle co...

NSDictionary can be enumerated using fast enumeration, just like other collection types: NSDictionary stockSymbolsDictionary = @{ @"AAPL": @"Apple", @"GOOGL": @"Alphabet", ...

appendToFile: Append single src, or multiple srcs from local file system to the destination file system. Also reads input from stdin and appends to destination file system. Keep the as - hdfs dfs -appendToFile [localfile1 localfile2 ..] [/HDFS/FILE/PATH..] cat: Copies source paths to stdout. ...

The command pattern encapsulates parameters to a method, current object state, and which method to call. It is useful to compartmentalize everything needed to call a method at a later time. It can be used to issue a "command" and decide later which piece of code to use to execute the comma...

To begin, npm install the desired loaders for your project. Inside of the configuration object that is being exported in webpack.config.js, a module property will hold all of your loaders. const source = `${__dirname}/client/src/`; module.exports = { // other settings here module: { ...

The pattern (p1, p2) is strict in the outermost tuple constructor, which can lead to unexpected strictness behaviour. For example, the following expression diverges (using Data.Function.fix): fix $ \(x, y) -> (1, 2) since the match on (x, y) is strict in the tuple constructor. However, the fo...

You can use the TextInputLayout to display error messages according to the material design guidelines using the setError and setErrorEnabledmethods. In order to show the error below the EditText use: TextInputLayout til = (TextInputLayout) findViewById(R.id.username); til.setErrorEnabled(true); ...

The TextInputLayout has a character counter for an EditText defined within it. The counter will be rendered below the EditText. Just use the setCounterEnabled() and setCounterMaxLength methods: TextInputLayout til = (TextInputLayout) findViewById(R.id.username); til.setCounterEnabled(true); til...

The TextInputEditText is an EditText with an extra fix to display a hint in the IME when in 'extract' mode. The Extract mode is the mode that the keyboard editor switches to when you click on an EditText when the space is too small (for example landscape on a smartphone). In this case, using an Ed...

double area; double h = 1.0 / n; #pragma omp parallel for shared(n, h, area) for (i = 1; i <= n; i++) { double x = h * (i - 0.5); #pragma atomic area += (4.0 / (1.0 + x*x)); } pi = h * area; In this example, each threads execute a subset of the iteration count and they accumula...

Include using System.Numerics and add a reference to System.Numerics to the project. using System; using System.Numerics; namespace Euler_25 { class Program { static void Main(string[] args) { BigInteger l1 = 1; BigInteger l2 = 1; ...

RAISERROR function will generate error in the TRY CATCH block: DECLARE @msg nvarchar(50) = 'Here is a problem!' BEGIN TRY print 'First statement'; RAISERROR(@msg, 11, 1); print 'Second statement'; END TRY BEGIN CATCH print 'Error: ' + ERROR_MESSAGE(); END CATCH RAISERROR ...

RAISERROR with severity (second parameter) less or equal to 10 will not throw exception. BEGIN TRY print 'First statement'; RAISERROR( 'Here is a problem!', 10, 15); print 'Second statement'; END TRY BEGIN CATCH print 'Error: ' + ERROR_MESSAGE(); END CATCH After RAISER...

You can re-throw error that you catch in CATCH block using TRHOW statement: DECLARE @msg nvarchar(50) = 'Here is a problem! Area: ''%s'' Line:''%i''' BEGIN TRY print 'First statement'; RAISERROR(@msg, 11, 1, 'TRY BLOCK', 2); print 'Second statement'; END TRY BEGIN CATCH print...

You can throw exception in try catch block: DECLARE @msg nvarchar(50) = 'Here is a problem!' BEGIN TRY print 'First statement'; THROW 51000, @msg, 15; print 'Second statement'; END TRY BEGIN CATCH print 'Error: ' + ERROR_MESSAGE(); THROW; END CATCH Exception with be ...
