Why is it urgent ? Does fresher not mean beginner ? That's what I expect it to mean. What is Axmscomm control ? Is it part of Windows ? Does it have documentation ? Why are you doing this task, why is it urgent, are you really a beginner to VB.NET AND SQL, and yet you're being asked to do this ?

hello

iam using mscomm control in vb.net , i read the data in the length of bytes , actually data showing is null , I declared the dim rbuf as string , while event is raising rbuf it shows null,how to resolve this problem,
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 )
eventcount = eventcount + 1
Label15.Text = eventcount

End Select
End Sub

Thanks
