    Thumbs up Give this a whirl

    Just use &H?, where ? is the hexadecimal number.

    Code:
    MsgBox &H100
'displays 256

    'Theres probably only one way strings containing hex can be converted to decimal
    Code:
    Function unhex(hex)
    a = Left(hex, 1)
    If a >= "A" Then a = Asc(a) - 55
    B = Right(hex, 1)
    If B >= "A" Then B = Asc(B) - 55
    unhex = Chr(a * 16 + B)
End Function
    Use
    writing software in C++ is like driving rivets into steel beam with a toothpick.
    writing haskell makes your life easier:
    reverse (p (6*9)) where p x|x==0=""|True=chr (48+z): p y where (y,z)=divMod x 13
    To throw away OOP for low level languages is myopia, to keep OOP is hyperopia. To throw away OOP for a high level language is insight.

    it's easier than that... just do this since we know a HEX result is a string

    Code:
      
  '' assumes HEX value has no id prefex ie 0x or &H
  Public Function HEX2DEC(ByRef hex_str As String) as Long
    
    HEX2DEC = CLng("&H" & hex_str)
    
  End Function
