c++ - Winapi get string width in pixels -

I am trying to create a method which gives me width of the string in pixels. My code is still there:

  inline zero getTextWidth (hwnd hwnd four * text) {size text size; GetTextExtentPoint32 (GetDC (HWD), Text, Stellen (Text, and Text Size); Return?; }   
 I know that I should use  LPtoDP  (), but the parameters should be numerically and the size of GetTextExtentPoint32 returns is not.  
 How can I convert it?   
 
 
  size  in both the height and width in the structure since you only care about breadth You are, of course,  LPtoDP (textSize.cx); .
