Here is a code snippet I'm having trouble with:
Code:
Select Case WaitCommEvent(hPort, commEvtMask, ComEvent)
Case 0 'Error
dwRet = Err.LastDllError
dwRetStr = Err.Description
Select Case dwRet
Case ERROR_IO_PENDING
OpenPortTxt = "I/O is pending..."
Case Else
OpenPortTxt = "Port " & PName & "Wait failed with error " & dwRet & " >> " & dwRetStr
End Select
Case Else 'Successful
If (dwEvtMask Or EV_CTS Or EV_DSR) Then
Form1.Text4.Text = serapi.RXport
OpenPortTxt = "It worked!"
End If
End SelectI'm not sure how to fix this or even troublshoot it!
Can someone help please?
Thanks,
Ken
