In the old days, appending text to a textbox meant concatenation  – something like:

TextBox1.Text=TextBox1.Text + myNewText

or:

TextBox1.Text+=MyNewText

Instead of this, we now have:

TextBox1.Text.AppendText(MyNewText)

This is for a use in which the StringBuilder class would be overkill. Plus, this has much less overhead than the older concatenation method also. It’s faster and more efficient. That’s all I needed to hear.
