推荐答案

你好

我在vb.net中使用mscomm控件，我读取了字节长度的数据，实际上显示的数据为null，我将dim rbuf声明为string，而事件引发的rbuf显示为null，如何解决此问题，
我在下面的mscommcontrol事件代码中发送了我的代码




私有子AxMSComm1_OnComm(ByVal发送者作为对象，ByVal e作为System.EventArgs)处理AxMSComm1.OnComm

选择案例AxMSComm1.CommEvent

案例MSCommLib.OnCommConstants.comEvReceive
rbuf = Asc(rbuf和AxMSComm1.Input)
Label22.Text =修剪(rbuf)
Label14.Text = Len(rbuf)

如果Len(rbuf)= 6，则写入文件(rbuf)
eventcount = eventcount + 1
Label15.Text = eventcount

结束选择
结束子





谢谢

hello

i sent my code in the mscommcontrol event code it is in below




Private Sub AxMSComm1_OnComm(ByVal sender As Object, ByVal e As System.EventArgs) Handles AxMSComm1.OnComm

Select Case AxMSComm1.CommEvent

Case MSCommLib.OnCommConstants.comEvReceive
rbuf = Asc(rbuf & AxMSComm1.Input)
Label22.Text = Trim(rbuf )
Label14.Text = Len(rbuf )

If Len(rbuf )= 6 Then writetofile(rbuf )
