Line by Line Text Cycle

Description

This code will cycle through a text box or rich text box line by line, select the line and place it into a string array. The array will then be passed to another method where it will be placed into a list box excluding the blank lines.

I've seen other code like this but if there is no ending vbCrLf then the last line of the box is not read, I've fixed this and showed how to extract the line information and how to use it.

The code is slowed down using a pause routine that I made about a year ago.

Assumption is that this code is for beginners to experts
