changing values in byte array - [RESOLVED]

Hi,

I have a byte array which I would like to For-Next through byte by byte and change values as needed then write this array into an existing file.

Here's the code I'm using. It does not currently work. It breaks on line: Put tfNewArray(), tfParInt, BGColRef

I was using Put to change the value in the file directly but this is very slow. But I don't know what the equilivant to "Put" is when dealing with a byte array.

Thanks for any help.

VB Code:

Dim tfParInt As Long
        Dim rByteValHex_1 As Byte
        Dim rByteValHex2 As Byte
        Dim tfBGColRef As Byte
        Dim tfOthColRef As Byte
        Dim tfNewArray() As Byte
        ReDim tfNewArray(BOB_p1 To lngFileLen)
 
        tfBGColRef = 0
        tfOthColRef = BOB_FstByteColTblRef
        
        Seek #f, BOB_p1
        For tfParInt = BOB_p1 To lngFileLen
            rByteValHex_1 = argArray_raster(tfParInt)
            
            If rByteValHex_1 = BOB_FstByteColTblRef Then
                'MsgBox ("here 1")
                Put tfNewArray(), tfParInt, tfBGColRef
                GoTo NexttfParInt
            Else
                If rByteValHex_1 = 0 Then
                    Put tfNewArray(), tfParInt, tfOthColRef
                End If
            End If
NexttfParInt:
        Next tfParInt
 
        Put #f, BOB_p1, tfNewArray()
