I am trying to pass a control of type MSComm to a dll. I have declared it as of type MSCommlib.MSComm. The initialization etc. for the comm port is done in the DLL. Now I want to use the OnComm event. Should I place it inside the DLL or in the form code where the MSComm control is placed. In either case the oncomm event is not getting fired even though the characters arrive in the receive buffer. I have set the RThreshold property to 1

Visual Basic is Microsoft’s event-driven programming language and integrated development environment (IDE) for its Component Object Model (COM) programming model. It is relatively easy to learn and use because of its graphical development features and BASIC heritage. It has been replaced with VB.NET, and is very similar to VBA (Visual Basic for Applications), the programming language for the Microsoft Office product line.
