Calculating the width in a windows situation is not trivial. It is dependent on the font, the point size, the bold or regular, the italic or not, etc..

Using Courier New 9 pitn regular non italic you can use this formula;

(NumChars*7)+10 for textboxes
(NumChars*7)+25 for comboboxes

Change the font or point size and that formula does not work anymore.
