Possible values are Continue | Ignore | Inquire | SilentlyContinue | Stop | Suspend. Value of this parameter will determine how the cmdlet will handle non-terminating errors (those generated from Write-Error for example; to learn more about error handling see [topic not yet created]).

//Add value to Isolated Storage Settings IsolatedStorageSettings.ApplicationSettings.Add("Key", "Value");

//Check if a value exists in settings already if (IsolatedStorageSettings.ApplicationSettings.Contains("Key")) { //perform logic }

string setting = IsolatedStorageSettings.ApplicationSettings["Key"] as string;

By default, Jsoup will display only block-level elements with a trailing line break. Inline elements are displayed without a line break. Given a body fragment, with inline elements: <select name="menu"> <option value="foo">foo</option> <option va...

The gridspec package allows more control over the placement of subplots. It makes it much easier to control the margins of the plots and the spacing between the individual subplots. In addition, it allows for different sized axes on the same figure by defining axes which take up multiple grid loca...

This is a simple implementation of Binary Search Tree Insertion using Python. An example is shown below: Following the code snippet each image shows the execution visualization which makes it easier to visualize how this code works. class Node: def __init__(self, val): self.l_chil...

TikZ provides syntax similar to DOT which you can use to tighten up your graph drawing code considerably. \documentclass{standalone} \usepackage{tikz} \usetikzlibrary{graphs,quotes,arrows.meta} \begin{document} \begin{tikzpicture} \graph[nodes={draw,circle},edges={-{Stealth[]}}] { ...

ls shows files and directories in present working directory. (if no arguments are passed.) (It doesn't show hidden files which starts with . by default.) user@ubuntu14:/usr$ ls bin games include lib lib32 local sbin share src To see all files (hidden files/folders also). Use ls -a OR l...

For Adding this to project you can find official doc easily but in this example I'm going to highlight some of the key areas to be taken care of. Step 1 :- Add google service dependencies { ... compile 'com.google.android.gms:play-services-appindexing:9.4.0' ... } Step...

For simple multi-threaded code, using synchronization is acceptable. However, using synchronization does have a liveness impact, and as a codebase becomes more complex, the likelihood goes up that you will end up with Deadlock, Starvation, or Livelock. In cases of more complex concurrency, using A...

After installing Tomcat with apt-get on Ubuntu xx.xx, Tomcat creates and uses these directories: $cd /etc/tomcat6/ ├── Catalina │   └── localhost │   ├── ROOT.xml │   └── solr.xml -> ../../../solr/solr-tomcat.xml ├── catalina.properties ├── context.xml ├── logging.properties ├── ...

type Meter = Double This simple approach has serious drawbacks for unit handling as every other type that is a Double will be compatible with it: type Second = Double var length: Meter = 3 val duration: Second = 1 length = duration length = 0d All of the above compiles, so in this case un...

case class Meter(meters: Double) extends AnyVal case class Gram(grams: Double) extends AnyVal Value classes provide a type-safe way to encode units, even if they require a bit more characters to use them: var length = Meter(3) var weight = Gram(4) //length = weight //type mismatch; found : Gr...

h = 1.0 / n; #pragma omp parallel for private(x) shared(n, h) reduction(+:area) for (i = 1; i <= n; i++) { x = h * (i - 0.5); area += (4.0 / (1.0 + x*x)); } pi = h * area; In this example, each threads execute a subset of the iteration count. Each thread has its local private copy ...
