Visual Basic's StrConv function can capitalize the first letter in every word in a string, but it doesn't handle special values like "O'Conner" and "I.B.M" correctly. This program demonstrates StrConv and a custom ProperCase function.
The ProperCase function looks through the string seeing which characters are letters and which are not. It capitalizes the first letter after any non-letter.

' Convert the text into proper case.
Function ProperCase(ByVal txt As String) As String
Dim txtlen As Long
Dim need_cap As Boolean
Dim i As Integer
Dim ch As String
txt = LCase(txt)
txtlen = Len(txt)
need_cap = True
For i = 1 To txtlen
ch = Mid$(txt, i, 1)
If ch >= "a" And ch <= "z" Then
If need_cap Then
Mid$(txt, i, 1) = UCase$(ch)
need_cap = False
End If
Else
need_cap = True
End If
Next i
ProperCase = txt
End Function

This function may not handle all special cases correctly but it does a better job than StrConv for this type of example.
