If the source collection is of a type that is not immutable, elements accessed through a ReadOnlyCollection can be modified. public class Item { public string Name { get; set; } public decimal Price { get; set; } } public static void FillOrder() { // An order is generated ...

Prerequisites Install pods in your project Install the GooglePlaces SDK Enable location services First we need to get the users location by getting their current longitude and latitude. Import GooglePlaces and GooglePlacePicker import GooglePlaces import GooglePlacePicker Add the...

The break statement, on execution makes the current loop to force exit package main import "fmt" func main() { i:=0 for true { if i>2 { break } fmt.Println("Iteration : ",i) i++ } } The continue statement, on execution...

By default, when data is imported to the PowerBI Desktop, each table or query stores data source details separately, even if they use the same data source. This makes it tedious, for example, to change the source database of an entire PowerBI report - which requires changing each query source param...

Normally, we opt this approach if we want complete encapsulation and don't want to make our methods public. Ascx <div style="width: 100%;"> <asp:Button ID="btnAdd" runat="server" Text="Add" OnClick="btnAdd_Click"></asp:butto...

void parallelAddition (unsigned N, const double *A, const double *B, double *C) { unsigned i; #pragma omp parallel for shared (A,B,C,N) private(i) schedule(static) for (i = 0; i < N; ++i) { C[i] = A[i] + B[i]; } } This example adds two vector (A and B into...

SAML specifies three key roles: The Identity Provider (IdP) The party which provides and maintains the identity of the users. This can be a directory service like ADFS or a custom database solution. The Service Provider (SP) The Service Provider is the actual service which the user tries...

Define the variables within a formula field: Shared NumberVar x := 1000; Shared NumberVar y; Assigning the values is optional. To display the variable in a second formula later on in the report, the call is nearly identical: Shared NumberVar x; x

In many application it is necessary to compute the function of two or more arguments. Traditionally, we use for-loops. For example, if we need to calculate the f = exp(-x^2-y^2) (do not use this if you need fast simulations): % code1 x = -1.2:0.2:1.4; y = -2:0.25:3; for nx=1:lenght(x) for n...

Protractor allows tests to be set as pending. This means that protractor will not execute the test, but will instead output: Pending: 1) Test Name Temporarily disabled with xit Or, if disabled with xdescribe(): Pending: 1) Test Name No reason given Combinations A xit() within an xdesc...

You can use the IFA for measuring ad clicks and the IFV for measuring app installs. IFA has built-in privacy mechanisms that make it perfect for advertising. In contrast, the IFV is for developers to use internally to measure users who install their apps. IFA ASIdentifierManager class pr...

A bit-field is used to club together many variables into one object, similar to a structure. This allows for reduced memory usage and is especially useful in an embedded environment. e.g. consider the following variables having the ranges as given below. a --> range 0 - 3 b --> range 0 -...

All programming languages allow us to assign values to variables. Usually, a value is assigned to variable, standing on left side. The prototype of the overall assignment operations in any contemporary programming language looks like this: left_operand assignment_operand right_operand instructions_...

Though Go supports ++ and -- operators and the behaviour is found to be almost similar to c/c++, variables with such operators cannot be passed as argument to function. package main import ( "fmt" ) func abcd(a int, b int) { fmt.Println(a," &...
