When the modem transmission is finished, the application receives a LINE_CALLSTATE message, which informs it that the state of a line device has changed. In this example, a remote disconnect has occurred. The application disconnects the call at the local end (it "goes on-hook") with lineDrop. Alternatively, the application itself may choose to end the call by invoking lineDrop before receiving the remote-disconnect message.

1. The application calls lineDrop, which places the call in the IDLE state. The call still exists, and the application still has its handle. Now the application can examine the call-information record, if desired.

2. The application calls lineDeallocateCall to release the call handle for the finished call. The call no longer exists.

3. If the application expects no more calls on the line, it uses lineClose to close the line. At this point, there will be no more incoming or outgoing calls on that line.

4. The application invokes lineShutdown to end the use of TAPI's functions for the current session.

		Nostalgia .Net		.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes.  More »
