>>>I don't understand the use of TXTWIDTH in the codes, is the code suppose to change the textbox width everytime textbox.value is changed?

>I know the width is going to vary for different content, that is why I intend to find a textbox width which can hold whatever content/string as long as it is a 32 chars string. i.e. I am trying to find how wide (the widest possible width in pixel) can a 32 string be, under certain font.

In English the 'W' is is the widest character. You van use a string of 32 Ws to calculate the width.
