Knowing the current screen font size (Small or Large) in use 
on the target system is often required when writing 
control-resizing routines. The wrapper function presented 
here, calling the Windows API GetDeviceCaps, returns True if 
the system is using the Small Font, and False if the system 
is in Large Font mode. Add the following code to a BAS module:

Option Explicit
Public Declare Function GetDesktopWindow Lib "user32" () As Long
Public Declare Function GetDC Lib "user32" (ByVal hwnd As Long) As Long
Public Declare Function GetDeviceCaps Lib "gdi32" (ByVal hdc As Long, ByVal nIndex As Long) As Long
Public Declare Function ReleaseDC Lib "user32" (ByVal hwnd As Long, ByVal hdc As Long) As Long
Public Const LOGPIXELSX = 88
Public Const LOGPIXELSY = 90
Private Sub Command1_Click()

If IsScreenFontSmall() Then
