Patch byte in external file


I'd like to patch byte in external file. How can I do that?


The following function can be used to solve the problem of patching:

Public Function PatchByte(ByVal vstrFilePath As String, _
                          ByVal vlngOffset As Long, _
                          ByVal vbytValue As Byte)
    Dim intFn As Integer
    intFn = FreeFile
    Open vstrFilePath For Binary Access Write As #intFn
    Put #intFn, vlngOffset, vbytValue
    Close intFn
End Function
