The RangeValidator control verifies that the input value falls within a predetermined range. It has three specific properties: PropertiesDescriptionTypeIt defines the type of the data. The available values are: Currency, Date,MinimumValueIt specifies the minimum value of the range.MaximumValueIt s...

To turn a Javascript Date object into a moment (moment object) just call moment and pass the Date as a argument moment(new Date()); // Moment {_isAMomentObject: true, _i: Sun Jul 31 2016 11:08:02 GMT+0300 (Jerusalem Daylight Time), _isUTC: false, _pf: Object, _locale: Locale…} To turn the momen...

When only a single argument is supplied to numpy's where function it returns the indices of the input array (the condition) that evaluate as true (same behaviour as numpy.nonzero). This can be used to extract the indices of an array that satisfy a given condition. import numpy as np a = np.arang...

Simply-expanded variables behave like variables from traditional programming languages. The expression on the right-hand side is evaluated, and the result is stored in the variable. If the right-hand side contains a variable reference, that variable is expanded before the assignment takes place. ...

When defining a recursively-expanded variable, the contents of the right-hand side are stored as-is. If a variable reference is present, the reference itself is stored (not the value of the variable). Make waits to expand the variable references until the variable is actually used. x = hello y =...

The += operator is a common extension that adds the specified content to the end of the variable, separated by a space. x = hello x += world Variable references in the right-hand side will be expanded if and only if the original variable was defined as a simply-expanded variable.

The sequence for an error is usually: error is triggered by looking up the error name in errordict and executing this procedure. the errordict procedure calls signalerror, passing it the error name. signalerror takes snapshots of the stacks, saving the snapshots in $error, and then calls stop. ...

Most of the tools are standardized with the exception of the name of the operator to throw an error. In Adobe interpreters, it is called .error. In ghostscript, it is called signalerror. So with this line you can use signalerror in postscript code for Adobe interpreters or ghostscript or xpost. /.e...

Since the final action of the default error handler is to call stop, you can catch errors from operators by enclosing code in a { ... } stopped construct. { 0 array 1 get } stopped { $error /errorname get = } if will print "rangecheck", the error signaled by get when t...

The documentation for docker events provides details, but when debugging it may be useful to launch a container and be notified immediately of any related event: docker run... & docker events --filter 'container=$(docker ps -lq)' In docker ps -lq, the l stands for last, and the q for quiet. Th...

For templated code it is often useful to verify that for function attributes (e.g. @nogc are inferred correctly. To ensure this for a specific test and thus type the entire unittest can be annotated @safe @nogc pure nothrow unittest { import std.math; assert(exp(0) == 1); assert(l...

In the scenario that a controller throws an exception, we can define exception handler methods to build and return specific responses. It is important to note that the defined exception handlers within the given controller will only apply to exceptions that occur within that controller. @Controller...

We're going to build an application that stores POJOs in a database. The application uses Spring Data JPA to store and retrieve data in a relational database. Its most compelling feature is the ability to create repository implementations automatically, at runtime, from a repository interface. Main...

As an alternative to using Html.ActionLink to generate links in a view, you can use Html.RouteLink To make use of this feature, you need to configure a route, for example: public static void RegisterRoutes(RouteCollection routes) { routes.MapRoute( "SearchResults", "{...

Usually the case when one wants to change a field type to another, for instance the original collection may have "numerical" or "date" fields saved as strings: { "name": "Alice", "salary": "57871", "dob": "198...

This example demonstrates how to use Renderscript API to blur an image (using Bitmap). This example uses ScriptInstrinsicBlur provided by android Renderscript API (API >= 17). public class BlurProcessor { private RenderScript rs; private Allocation inAllocation; private Allo...
