Calculate MD5 hash of a file [resolved]

I need to calculate MD5 hash value of a file. I've been searching around but with no luck.

Anyone have any pointers or ideas?

Should I give you the full code ? :D or should I give you the MD5 class, and you'll take it from there ?

Anyway is fine with me :)

Here:

VB Code:

Option Explicit
 
Private Function GetFileMD5(ByVal FileName As String) As String
    Dim MD5 As New clsMD5, FF As Integer, Buff() As Byte
    Const BuffSize As Long = 2 ^ 16 ' (64 KBytes)
    
    On Error GoTo ErrExit
    FF = FreeFile
    Open FileName For Binary Access Read As FF
        MD5.MD5Init
        
        Do Until Loc(FF) >= LOF(FF)
            If Loc(FF) + BuffSize > LOF(FF) Then
                ReDim Buff(LOF(FF) - Loc(FF) - 1)
            Else
                ReDim Buff(BuffSize - 1)
            End If
            
            Get FF, , Buff
            MD5.MD5Update UBound(Buff) + 1, Buff
        Loop
        
        MD5.MD5Final
        GetFileMD5 = MD5.GetValues
    Close FF
    
    Exit Function
ErrExit:
    Err.Clear
    GetFileMD5 = ""
End Function
 
Private Sub Form_Load()
    Debug.Print GetFileMD5("C:\Test_001.wav")
End Sub

Hehe :blush:

VB Code:

Private Sub Form_Load()
    Dim MD5 As New clsMD5
    Debug.Print MD5.DigestFileToHexStr("C:\Test_001.wav")
End Sub

I just noticed, the class does it for you :D (DigestFileToHexStr...)

[edit]
Well, at least with my code you can add a progress bar to it :)

works great! Thanks :)
