VB properties

Hello.
I'm using VB6, and I've made many applications, but I am interesting how to 
arrange some control properties, such as:Left, Right, Height, and Width.
Sometimes I have troubles when sided users runs my applications, because they 
says that text appears outside the control, or overlaps left or right edge, etc.
I am interesting what values are the best for:left, right, width, and height 
properties, for the controls such as:CommandButtons, TextBoxes, Labels, etc, 
and what values are the best and for same properties of the form.
The best regards.
