ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo Info = cm.getActiveNetworkInfo(); if (Info == null || !Info.isConnectedOrConnecting()) { Log.i(TAG, "No connection"); } else { ...

To check exact strength in decibels use this- ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo Info = cm.getActiveNetworkInfo(); if (Info == null || !Info.isConnectedOrConnecting()) { Log.i(TAG, "No connection");...

A document can be created by using the CreateDocumentAsync method of the DocumentClient class. Documents are user defined (arbitrary) JSON content. async Task CreateFamilyDocumentIfNotExists(DocumentClient client, string databaseName, string collectionName, Family family) { try { ...

DocumentDB supports rich queries against JSON documents stored in each collection. With a LINQ query IQueryable<Family> familyQuery = this.client.CreateDocumentQuery<Family>( UriFactory.CreateDocumentCollectionUri(databaseName, collectionName), queryOptions) .Where(f => f....

DocumentDB supports replacing JSON documents using the ReplaceDocumentAsync method of the DocumentClient class. await client.ReplaceDocumentAsync(UriFactory.CreateDocumentUri(databaseName, collectionName, familyName), updatedFamily);

DocumentDB supports deleting JSON documents using the DeleteDocumentAsync method of the DocumentClient class. await client.DeleteDocumentAsync(UriFactory.CreateDocumentUri(databaseName, collectionName, documentName));

Set up some constants for the server and authentication information. Assuming LDAPv3, but it's easy enough to change that. // Authentication, and the name of the server. private const string LDAPUser = "cn=example:app:mygroup:accts,ou=Applications,dc=example,dc=com"; private readonly ch...

Entity Framework (EF) is an object-relational mapper that enables .NET developers to work with relational data using domain-specific objects. It eliminates the need for most of the data-access code that developers usually need to write. Entity Framework allows you to create a model by writing cod...

Note: in the subsequent passages, the terms hash map and hash table are used interchangeably and refer to the same concept, namely, a data structure providing efficient key lookup through use of an internal hash function. Introduction Although R does not provide a native hash table structure, simi...

Like most of the other programming languages, T-SQL also supports IF..ELSE statements. For example in the example below 1 = 1 is the expression, which evaluates to True and the control enters the BEGIN..END block and the Print statement prints the string 'One is equal to One' IF ( 1 = 1) --<-...

We can use multiple IF statement to check multiple expressions totally independent from each other. In the example below, each IF statement's expression is evaluated and if it is true the code inside the BEGIN...END block is executed. In this particular example, the First and Third expressions are ...

In a single IF..ELSE statement, if the expression evaluates to True in the IF statement the control enters the first BEGIN..END block and only the code inside that block gets executed , Else block is simply ignored. On the other hand if the expression evaluates to False the ELSE BEGIN..END block ge...

If we have Multiple IF...ELSE IF statements but we also want also want to execute some piece of code if none of expressions are evaluated to True , then we can simple add a final ELSE block which only gets executed if none of the IF or ELSE IF expressions are evaluated to true. In the example below...

More often than not we need to check multiple expressions and take specific actions based on those expressions. This situation is handled using multiple IF...ELSE IF statements. In this example all the expressions are evaluated from top to bottom. As soon as an expression evaluates to true, the cod...
