The IsNull() function accepts two parameters, and returns the second parameter if the first one is null. Parameters: check expression. Any expression of any data type. replacement value. This is the value that would be returned if the check expression is null. The replacement value must be of a...

Since null is not a value, you can't use comparison operators with nulls. To check if a column or variable holds null, you need to use is null: DECLARE @Date date = '2016-08-03' The following statement will select the value 6, since all comparisons with null values evaluates to false or unknown...

Service is available in run phase. The Service recipe produces a service just like the Value or Factory recipes, but it does so by invoking a constructor with the new operator. The constructor can take zero or more arguments, which represent dependencies needed by the instance of this type. ...

Provider is available both in configuration and run phases. The Provider recipe is syntactically defined as a custom type that implements a $get method. You should use the Provider recipe only when you want to expose an API for application-wide configuration that must be made before the appli...

<Image Source="ms-appx:///Assets/Windows_10_Hero.png"/> Your image is part of the application, in the Assets folder and marked as Content <Image Source="ms-appdata:///local/Windows_10_Hero.png"/> Your image was saved in your application's Local Folder <Imag...

ImageSource result = new BitmapImage(new Uri("ms-appx:///Assets/Windows_10_Hero.png")); Use result to set the Source property of an Image control either though a Binding or code-behind

Quick start A rule describes when and how certain files (rule's targets) are created. It can also serve to update a target file if any of the files required for its creation (target's prerequisites) are newer than the target. Rules follow the syntax below: (Note that commands following a rule are ...

A while loop is used to execute a piece of code while a condition is true. The while loop is to be used when a block of code is to be executed a variable number of times. For example the code shown gets the user input, as long as the user inserts numbers which are not 0. If the user inserts 0, the ...

The pipe (%>%) operator could be used in combination with dplyr functions. In this example we use the mtcars dataset (see help("mtcars") for more information) to show how to sumarize a data frame, and to add variables to the data with the result of the application of a function. librar...

Writing with roxygen2 roxygen2 is a package created by Hadley Wickham to facilitate documentation. It allows to include the documentation inside the R script, in lines starting by #'. The different parameters passed to the documentation start with an @, for example the creator of a package will by...

In certain cases we need to cancel an image download request in Picasso before the download has completed. This could happen for various reasons, for example if the parent view transitioned to some other view before the image download could be completed. In this case, you can cancel the image down...

Copy and Paste following class in your package: public class MLRoundedImageView extends ImageView { public MLRoundedImageView(Context context) { super(context); } public MLRoundedImageView(Context context, AttributeSet attrs) { super(context, attrs); } ...
