vb.net 如何處理條碼機輸入

條碼機所做的動作, 是等同鍵盤 輸入, 然後最後鍵入"enter"而已. 即只要處理 keyboard keydown或keypress event便可, 例子如下,

Public Sub textbox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) handles textbox1.keypress

Dim strChar As String
If Asc(e.KeyChar) = 13 Then ' 13 代表鍵盤輸入鍵
..... 你的程式
End If
End Sub
