/* FlexibleMessageBox A flexible replacement for the .NET MessageBox
*
* Author: Jörg Reichert (public@jreichert.de)
* Contributors: Thanks to: David Hall, Roink
* Version: 1.3
* Published at: http://www.codeproject.com/Articles/601900/FlexibleMessageBox
*
************************************************************************************************************
* Features:
* - It can be simply used instead of MessageBox since all important static "Show"-Functions are supported
* - It is small, only one source file, which could be added easily to each solution
* - It can be resized and the content is correctly word-wrapped
* - It tries to auto-size the width to show the longest text row
* - It never exceeds the current desktop working area
* - It displays a vertical scrollbar when needed
* - It does support hyperlinks in text
*
* Because the interface is identical to MessageBox, you can add this single source file to your project
* and use the FlexibleMessageBox almost everywhere you use a standard MessageBox.
* The goal was NOT to produce as many features as possible but to provide a simple replacement to fit my
* own needs. Feel free to add additional features on your own, but please left my credits in this class.
*
************************************************************************************************************
* Usage examples:
*
* FlexibleMessageBox.Show("Just a text");
*
* FlexibleMessageBox.Show("A text",
* "A caption");
*
* FlexibleMessageBox.Show("Some text with a link: www.google.com",
* "Some caption",
* MessageBoxButtons.AbortRetryIgnore,
* MessageBoxIcon.Information,
* MessageBoxDefaultButton.Button2);
*
* var dialogResult = FlexibleMessageBox.Show("Do you know the answer to life the universe and everything?",
* "One short question",
* MessageBoxButtons.YesNo);
*

************************************************************************************************************
* History:
* Version 1.3 - 19.Dezember 2014
* - Added refactoring function GetButtonText()
* - Used CurrentUICulture instead of InstalledUICulture
* - Added more button localizations. Supported languages are now: ENGLISH, GERMAN, SPANISH, ITALIAN
* - Added standard MessageBox handling for "copy to clipboard" with <Ctrl> + <C> and <Ctrl> + <Insert>
* - Tab handling is now corrected (only tabbing over the visible buttons)
* - Added standard MessageBox handling for ALT-Keyboard shortcuts
* - SetDialogSizes: Refactored completely: Corrected sizing and added caption driven sizing
*
* Version 1.2 - 10.August 2013
* - Do not ShowInTaskbar anymore (original MessageBox is also hidden in taskbar)
* - Added handling for Escape-Button
* - Adapted top right close button (red X) to behave like MessageBox (but hidden instead of deactivated)
*
* Version 1.1 - 14.June 2013
* - Some Refactoring
* - Added internal form class
* - Added missing code comments, etc.
*
* Version 1.0 - 15.April 2013
* - Initial Version
