How to Increase Productivity

Unlocking productivity is one of the bigger concerns for any person taking a management role. However, people rarely agree on the best approaches to improve performance.

 * This "facade" class makes it easier to work with a hyperlink field in a Word document.
 * A hyperlink is represented by a HYPERLINK field in a Word document. A field in Aspose.Words
 * consists of several nodes and it might be difficult to work with all those nodes directly.
 * Note this is a simple implementation and will work only if the hyperlink code and name
 * each consist of one Run only.
 * [FieldStart][Run - field code][FieldSeparator][Run - field result][FieldEnd]
 * The field code contains a string in one of these formats:
 * HYPERLINK "url"
 * HYPERLINK \l "bookmark name"
 * The field result contains text that is displayed to the user.

Walking in the Open Source Component Garden

The good news is that open source projects release newer versions of their components that address newly found vulnerabilities. Bug-free alternatives are available. But making use of these newer more secure versions, relies on ensuring your organization has a process to identify these defects easily and early.
