CodeSense is a control that allows you to have syntax highlighing, autocomplete and function tooltips in an edit control. Unfortunately, it doesn't include a proper VB example. This example shows you how to properly use the CodeSense control in Visual Basic, providing AutoComplete, function tooltips and syntax highlighting. If you go to https://www.dansoftaustralia.com/index.php/3/1 then you can see some screenshots of stuff you can do with the control (the last 2 screenshots aren't included).
NOTE: you will need to download the CodeSense control (version 2.22) from https://member.telpacific.com.au/daniel15/cmcs21.ocx and register it for this code to work.
