买 股票 当天 全部卖:想制作一个ACTIVE X控件，用于串口数据实时采集，其中添加1个MS-COMMON，和两个TIMER，

MScommon有自己的事件触发（就是那个OnComm消息)，你还要监控别的吗？
OnComm可以监控一下事件：
' Errors
comEventBreak ' Break was received.
comEventFrame ' Framing Error
comEventOverrun ' Data Lost.
comEventRxOver ' Receive buffer overflow.
comEventRxParity ' Parity Error.
comEventTxFull ' Transmit buffer full.
comEventDCB ' Unexpected error retrieving DCB]

' Events
comEvCD ' Change in the CD line.
comEvCTS ' Change in the CTS line.
comEvDSR ' Change in the DSR line.
comEvRing ' Change in the Ring Indicator.
comEvReceive ' Received RThreshold # of
' chars.
comEvSend ' There are SThreshold number of
' characters in the transmit
' buffer.
comEvEof ' An EOF charater was found in
' the input stream

呵呵！！不懂！！
