thanks for the help and apologies I have mild autism which make learning little more difficult than the average person

I worked out a code which i think maybe right


HTML Code:
Private Sub Button9_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button9.Click
        Dim FileToCopy As String
        Dim NewCopy As String

        FileToCopy = "c:\toolbox\nandpro\nand1.bin"
        NewCopy = "c:\toolbox\360multi\data\my360\nanddump.bin"

        If IO.File.Exists(NewCopy) = True Then

        End If
        Dim overwrite As Integer


        overwrite = MessageBox.Show("Do you want to overwrite the existing file", "Overwrite file?", MessageBoxButtons.YesNo, MessageBoxIcon.Question)

        If overwrite = vbYes Then
            System.IO.File.Delete(NewCopy)

            System.IO.File.Copy(FileToCopy, NewCopy)
            MessageBox.Show("Successfully Copied" & vbNewLine & FileToCopy & "to" & NewCopy)
        ElseIf overwrite = vbNo Then
        End If

    End Sub
