width of String GetTextExtentPoint32

Hello

I am trying to find any VBA code and not just an VB function. I want to find the width of a form label's text which I have placed on a label but it is driving me nuts. I have seen many forums' comments related to this question. Many of them talk about using API's like GetTextExtentPoint32 but I have not seen yet how to build this code.

Thanks

i have a activex dll to get textwidth and textheight for any control or range
pm me if you are interested
