Set this property to indicate which line device should be used. All available devices are listed in the DeviceList property. Legal values for this property are 0 to ThbTapiLine.DeviceList.Count -1. The DeviceName property is set to the corresponding name.
 |
Your application should not save the DeviceID to restore an user sphone configuration because it could change in due to installing/removing TAPI-devices. The better choice is to store the DeviceName. The PermanentDeviceID can be used to handle the problem of identical device names. |
The DeviceList property is of type TStrings. The TStrings.Objects property is used the store the DeviceID together with the device name. So you are able to assign this list to a ComboBox, sort the list and get the DeviceID back by type-casting the Objects propertiy to Integer. Do not sort the ThbTapiLine.DeviceList, use always a copy to do so.
Example
| for i := 0 to hbTapiLine1.DeviceList.Count-1
do begin hbTapiLine1.DeviceID := i; if hbTapiLine1.Available then begin ListBox1.Items.Add(hbTapiLine1.DeviceName + ' is available'); end; end; |

Design-Time: None / Run-Time: Read, Write
Declaration
property DeviceID: Integer;
Remarks
If the device is active prior to setting the DeviceID, then you must deactivate the component (ThbTapiLine.Active := False) otherwise an exception will be raised. Your application should not save the DeviceID to restore an users configuration because it could change in due to installing/removing TAPI-devices. The better choice is to store the DeviceName.
