you cannot use a port to which a mouse is connected, as windows would have already opened it.

Also the olecontrol.portopen setting is at best unreliable.Whenever I used the MSComm I always maintained my own flag rather than reading the above property.



>hello all, i am having some problems with the mscomm control. I set all of my properties at design time, but set them again at run time. I have a mouse that can be plugged into com port 1. when the code runs oleComm1.PortOpen = .F., but when i try oleComm1.PortOpen = .T., i get the error port already open, if I try oleComm1.PortOpen = .F., i get the error type mismatch. is there some pc setting i am missing? or something i can do to correct this problem.
