This DLL extends the
RichTextBox control in Windows Forms to add background highlighting color, background color clearing, highlighting and 'Scroll To Bottom' support. The article on CodeProject by Frederick Volking entitled "RichTextBox with background highlighting in VB.NET" does pretty much the same as this, only his article edits the color tables and RTF text currently used in the RichTextBox. My version uses calls on the RichTextBox directly to highlight/clear selections.
A stonking 4 (count them) methods are added to the
RichTextBox.SelectionBackColor (Property) - Gets or sets the current selection's backcolor. Used the same way as
RichTextBox.ClearBackColor (Sub) - Clears all or just the selected backcolor as though it was never there.
RichTextBox.Highlight (Sub) - Highlights the given text in the
RichTextBox with the given color.
RichTextBox.ScrollToBottom (Sub) - Scrolls the
RichTextBox to the bottom of the viewport.
Reusing the New RichTextBox
The release version of the dll is included in the demo project, simply reference this DLL and add the DLL to the toolbox, then drop the new
RichTextBox onto a form, then you are all done.
