I had a text box on a dialog and need to change the border style of it when
the mouse moved in the text box and out of the text box. I can use Text1_MouseMove
event to deliver the mouse move in action but found I never know when the user
moved the mouse out of it! ( cannot write function in the Form_MouseMove because
it's not always working fine )

Any good ways?
