Environment NewLine

Lets look over a function that will enable the inclusion of additional lines

Environment.NewLine

The use of the the Environment.NewLine option in VB.Net enables programmers to seperate content over a new line in an object. Say for example you have a button that when a user triggers it the event inputs a sentance or stucture of words in to an object (say a Rich Text Box). The text is reqiured to be shown over a number of lines in the object you would use the Environment.NewLine feature to enable this.
It is worth remembering that if you wish to make this happen with other elements within the code line, i.e. some text, you will need to add the + sign, as in the example below.

rtbHTML.Text.Insert(cursorposition, "<p>" + Environment.NewLine + Environment.NewLine + "</p>")

Selection Start

The selection start control indicates the insertion point, or caret, for new text. If you set this property to a location beyond the length of the text in the control, the selection start position will be placed after the last character. This control may be useful when considering the inclusion of information to a text area or rich text box. In the example below you can see that the value that is gathered from this control is stored in a variable so that if the program appends any information it can be called and input at this point.

Using the Activity Sheet, create a webpage editor, you should ensure that you pay close attention to the table provided in the instructions as this will provide you with the naming conventions that should be used when creating a program in VB.Net.
EXTENTION
Now that you have created the editor, create a button the inputs the simple HTML structure in to the Rich Text Box.
STRETCH & CHALLENGE
Now that you have this interactivity enabled in to your editor, try and enable the use to input tags at the point of where the cursor is in the Rich Text Box

The information covered in this page covers the knowledge and understanding linked to the criterion in the table below.
