各位大大
請問VB 2008,從外部8051讀BYTE進來.
因為我每一串資料的長度非固定,所以設2BYTE作抬頭 (0xFA,0X07,資料流...0xFA,0X07,資料流.....)
該怎麼找到每個抬頭後再抓資料流處理,有這個指令或技巧嗎. 不勝感激.
小弟剛學VB不久.QQ..請大大解惑.

'RS232傳輸
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Dim inByte() As Byte
Dim readcount As Integer
Dim check1 As Byte = 0
Dim check2 As Byte = 0

If RS232.BytesToRead <= 0 Then Exit Sub
ReDim inByte(RS232.BytesToRead - 1)
readcount = RS232.Read(inByte, 0, RS232.BytesToRead)
If readcount = 0 Then
Exit Sub
Else

For Each bData As Byte In inByte
TextBox1.Text = (Hex(bData) " ").ToString
Next
