Answer 1

Set the TextBox.SelectionStart property to the end of the string, and the TextBox.SelectionLength property to 0 .

Something like this:

int textLength = yourTextBox.Text.Length;
yourTextBox.SelectionStart = textLength;
yourTextBox.SelectionLength = 0;

Answer 2

You need to set the SelectionStart to the current text length. In VB, this is:

txtStatus.SelectionStart = txtStatus.Text.Length

If this is a multi-line textbox or if the text exceeds the visible width of the textbox, you also may need to scroll the selection point into view:

txtStatus.ScrollToCaret()
