Setting Focus inside a text box

[New_Coder]

How can I set the focus of to the end of the text in my text box. Clicking on a button I am populating a text box with code ie ShowThisText = "This is my Text" I then set the focus to the text box ie ShowThisText.setfocus The cursor by default is at the left of the "This is my Text" I want to be able to add on to the sentence without having to move to the right to start typing Any Ideas?

The code

TextBox1.SelectionStart = TextBox1.TextLength
TextBox1.Focus()

will put the cursor at the end of the text in TextBox1.
