1: ' Invisible Button Technique Demo
2: ' this project shows how to put the initial focus on an "invisible"
3: ' button (one with a width of zero). It will appear that no control
4: ' has the focus initially. this is especially useful when the control
5: ' that logically should have the lowest TabIndex is a RadioButton.
7: ' Once the invisible button loses the focus, we want to remove it from
8: ' the tab cycle (otherwise a user might get confused).
