A Cordova application runs as a website on a WebView component within the native mobile platform. Debugging a cordova application can therefore be done by utilizing your favourite browsers development tools. The following steps are needed to hook the application, running on the device, to the Chrome...
This method accepts a string as input, attempts to parse it into a DateTime, and returns a Boolean result indicating success or failure. If the call succeeds, the variable passed as the out parameter is populated with the parsed result.
If the parse fails, the variable passed as the out parameter i...
This method behaves as a combination of TryParse and ParseExact: It allows custom format(s) to be specified, and returns a Boolean result indicating success or failure rather than throwing an exception if the parse fails.

ABAP also offers the conventional WHILE-Loop which runs until the given expression evaluates to false. The system field sy-index will be increased for every loop step.
WHILE condition.
* do something
ENDWHILE
Without any addition the DO-Loop runs endless or at least until it gets explicitly exited from inside.
The system field sy-index will be increased for every loop step.
DO.
* do something... get it?
* call EXIT somewhere
ENDDO.
The TIMES addition offers a very convenient way to repeat code (a...
To break loops, the command EXIT can be used.

To skip to the next loop step, the command CONTINUE can be u...

Disclaimer: In no way does this example advocate the use of singletons. Singletons are to be used with a lot of care.
In PHP there is quite a standard way of implementing a singleton:
