The default position of an element is static. To quote MDN: This keyword lets the element use the normal behavior, that is it is laid out in its current position in the flow. The top, right, bottom, left and z-index properties do not apply. .element{ position:static; }

This example limits SELECT result to 100 rows. SELECT TOP 100 * FROM table_name; It is also possible to use a variable to specify the number of rows: DECLARE @CountDesiredRows int = 100; SELECT TOP (@CountDesiredRows) * FROM table_name;

This example limits SELECT result to 15 percentage of total row count. SELECT TOP 15 PERCENT * FROM table_name

$orderid = 12345; $order = Mage::getModel('sales/order')->load($orderid); The above code is roughly analogous to the following SQL query. select * from sales_flat_order where entity_id=12345;

$incrementid = 100000000; $order = Mage::getModel('sales/order')->loadByIncrementId($incrementid); The above code is roughly analogous to the following SQL query. select * from sales_flat_order where increment_id=100000000; The increment_id is the customer facing order identifier, whereas...

Filter an enumeration by using a conditional expression Synonyms: Where-Object where ? Example: $names = @( "Aaron", "Albert", "Alphonse","Bernie", "Charlie", "Danny", "Ernie", "Frank") $names | Where-Object {...

Sort an enumeration in either ascending or descending order Synonyms: Sort-Object sort Assuming: $names = @( "Aaron", "Aaron", "Bernie", "Charlie", "Danny" ) Ascending sort is the default: $names | Sort-Object $names | sort Aaron Aa...

You can group an enumeration based on an expression. Synonyms: Group-Object group Examples: $names = @( "Aaron", "Albert", "Alphonse","Bernie", "Charlie", "Danny", "Ernie", "Frank") $names | Group-Object -Prope...

Projecting an enumeration allows you to extract specific members of each object, to extract all the details, or to compute values for each object Synonyms: Select-Object select Selecting a subset of the properties: $dir = dir "C:\MyFolder" $dir | Select-Object Name, FullName, Att...

There are two types of using keyword usage, using statement and using directive: using statement: The using keyword ensures that objects that implement the IDisposable interface are properly disposed after usage. There is a separate topic for the using statement using directive The using...

raw_data = {'first_name': ['John', 'Jane', 'Jim'], 'last_name': ['Doe', 'Smith', 'Jones'], 'department': ['Accounting', 'Sales', 'Engineering'],} df = pd.DataFrame(raw_data,columns=raw_data.keys()) df.to_csv('data_file.csv')

public class Singleton { private static final Singleton INSTANCE = new Singleton(); private Singleton() {} public static Singleton getInstance() { return INSTANCE; } } It can be argued that this example is effectively lazy initialization. Section 12.4.1 of ...

countMatches method from org.apache.commons.lang3.StringUtils is typically used to count occurences of a substring or character in a String: import org.apache.commons.lang3.StringUtils; String text = "One fish, two fish, red fish, blue fish"; // count occurrences of a substring Str...

Start with an iterable which needs to be grouped lst = [("a", 5, 6), ("b", 2, 4), ("a", 2, 5), ("c", 2, 6)] Generate the grouped generator, grouping by the second element in each tuple: def testGroupBy(lst): groups = itertools.groupby(lst, key=lambda...

A Bootstrap carousel is a Bootstrap component that creates a slideshow which cycles through elements within the carousel. Here is a basic HTML usage example: <div id="carousel-example-generic" class="carousel slide" data-ride="carousel"> <!-- Indicators --...

Carousel components can be instantiated via jQuery with the function $('.carousel').carousel(options), where $('.carousel') is a top-level reference to the specific carousel and options is a Javascript object specifying the carousel's default attributes. The options object allows for multiple prope...

using System; using Xamarin.Forms; namespace NavigationApp { public class App : Application { public App() { MainPage = new NavigationPage(new FirstPage()); } } public class FirstPage : ContentPage { Label FirstPage...

The arc4random_uniform() function is the simplest way to get high-quality random integers. As per the manual: arc4random_uniform(upper_bound) will return a uniformly distributed random number less than upper_bound. arc4random_uniform() is recommended over constructions like ''arc4random() % uppe...

The following code demonstrates usage of arc4random_uniform() to generate a random integer between 3 and 12: uint32_t randomIntegerWithinRange = arc4random_uniform(10) + 3; // A random integer between 3 and 12 This works to create a range because arc4random_uniform(10) returns an integer between...

When referring to a worksheet, a range or individual cells, it is important to fully qualify the reference. For example: ThisWorkbook.Worksheets("Sheet1").Range(Cells(1, 2), Cells(2, 3)).Copy Is not fully qualified: The Cells references do not have a workbook and worksheet associated ...
