請問版上大大,
小弟使用2008VB.NET做通訊連線, 語法如下:
Public Class Form1
Public ModbusASCII1 As New ModbusASCII '
Dim station As Integer = 1 '站號
Dim ech As Integer
Private Sub chkOpenCOM_CheckedChanged(ByVal sender As System.Object,
ByVal e As System.EventArgs) Handles chkOpenCOM.CheckedChanged
If chkOpenCOM.Checked = True Then
ech = ModbusASCII1.Open_Comm(ComPort.Text, 9600, "e", 7, 1) '
Else
ModbusASCII1.Close_comm(ComPort.Text)
End If
End Sub
Private Sub ComPort_SelectedIndexChanged(ByVal sender As System.Object,
ByVal e As System.EventArgs) Handles ComPort.SelectedIndexChanged
If chkOpenCOM.Checked = True Then
ech = ModbusASCII1.Open_Comm(ComPort.Text, 9600, "e", 7, 1)
Else
ModbusASCII1.Close_comm(ComPort.Text)
End If
End Sub
End Class
編譯程式出現時出現:
InvalidOperationException未處理,
是語法錯誤嗎?
謝謝!
