To let a user change a font name, load all the fonts into a combo box:
Private Sub Form_Load()
' Determine the number of screen
For I = 0 To Screen.FontCount - 1
' Put each font into list box.
Make this more useful by letting your users see what the font looks like immediately after selecting it without
having to "test" it by typing something:
Private Sub cboFont_Click()
'Set the FontName of the combo box
'to the font that was selected.
cboFont.FontName = cboFont.Text
