You can use the MCI part in your views by making a few
connections:
The MtMCI part does not exist on the parts palette so it must be added using the Add Part choice in the Options menu. When the push button is clicked, take the contents of the entry field and pass the contents (the command string) to the send: action of the MCI part. The operating system returns the returnString from the mciSendString call.
Of course, you can make this much more elaborate. For example, you might have a list that keeps track of all the strings that have been sent as well as their return values. Or you might want a list of pre-built messages to send one at a time.
