Question

Need a function that takes a character as a parameter and returns true if it is a letter.

Answer 1

Seanyboy’s IsCharAlphaA answer is close. The best method is to use the W version like so:

Private Declare Function IsCharAlphaW Lib 'user32' (ByVal cChar As Integer) As Long Public Property Get IsLetter(character As String) As Boolean     IsLetter = IsCharAlphaW(AscW(character)) End Property 

Of course, this all rarely matters as all of VB6’s controls are ANSI only
