- /* 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
