Hi guys 'n gals,

I have a phone line attached to my computer's modem, I would like to make a bit of software which will, detect when a phone rings up the line connected to the computer, and tell me the number of the caller. Anybody have any ideas on this?

Cheers!

Use the CallNotificationEvent() to capture the CallerID...  This example is in VB.Net but could easily be converted to C# >:)

Hi,

Thanks for the link, it's quite a large bit of code in there doing numerous different things, am I right in assuming I only need the following?


Import TAPI3Lib

        Private Sub CallNotificationEvent()
            ' here we should check to see various notifications of new and ended calls

            Select Case CallNotificationObject.Event

                Case CALL_NOTIFICATION_EVENT.CNE_MONITOR
                    ' the notification is for a monitored call

                Case CALL_NOTIFICATION_EVENT.CNE_OWNER
                    ' the notification is for an owned call
            End Select

        End Sub




and merely, convert that to C#, or do I need more for what I am trying to achieve?

This is the event handler portion that you would need as well to process the event:
        Private CallInfoObject As ITCallInfoChangeEvent
        Private Sub CallInfoEvent()
            ' here you can extract information from the call

            'the code to extract the caller ID
            ' >>> put the following code in a try block and swallow the exception if it gives errors
            Dim CallerID As String
            CallerID = CallInfoObject.Call.CallInfoString(CALLINFO_STRING.CIS_CALLERIDNAME)

        End Sub

Sorry to sound a bit daft, but what triggers the function call when the Modem is contacted by an outside phone line? Should I have something checking the status every few seconds, or how does this work?


Cheers!

the code example that wz on codeproject creates a "listener" that connects to the TAPI... so you should not need anything more there...
