Of course it's possible. You just need to keep track of the current location and change the value to the new location on each tick of the timer.
For example, to move it from one textbox to another, you could do something like this:
- Txt1.Text = "";
-
Txt2.Text = "H";
Of cource, you wouldn't explicitly specify the control in your code. But rather you would keep track of the current one and use the Form's Controls collection to access the current one and next one.
