phoneConfigDialog
The phoneConfigDialog
function causes the provider of the specified phone device to display a modal
dialog (attached to the application's hwndOwner) that allows the user to
configure parameters related to the phone device specified by dwDeviceID.
LONG phoneConfigDialog(
|
DWORD dwDeviceID, |
|
|
HWND hwndOwner, |
|
|
LPCSTR lpszDeviceClass |
|
|
); |
|
Parameters
dwDeviceID
The phone
device to be configured.
hwndOwner
A handle to a
window to which the dialog is to be attached. Can be a NULL value to indicate
that any window created during the function should have no owner window.
lpszDeviceClass
A pointer to
a NULL-terminated string that identifies a device class name. This device class
allows the application to select a specific subscreen of configuration
information applicable to that device class. This parameter is optional and can
be left NULL or empty, in which case the highest level configuration is
selected.
Return Values
Returns zero
if the request is successful or a negative error number if an error has
occurred. Possible return values are:
PHONEERR_BADDEVICEID,
PHONEERR_NOMEM, PHONEERR_INUSE, PHONEERR_OPERATIONFAILED, PHONEERR_INVALPARAM,
PHONEERR_OPERATIONUNAVAIL, PHONEERR_INVALDEVICECLASS, PHONEERR_RESOURCEUNAVAIL,
PHONEERR_INVALPOINTER, PHONEERR_UNINITIALIZED, PHONEERR_NODEVICE.
Remarks
The lpszDeviceClass
parameter allows the application to select a specific subscreen of
configuration information applicable to the device class in which the user is
interested; the permitted strings are the same as for phoneGetID. For
example, if the phone supports the wave API, passing "wave/in" as lpszDeviceClass
would cause the provider to display the parameters related specifically to wave
(or at least to start at the corresponding point in a multilevel configuration
dialog chain, eliminating the need to search for relevant parameters).
The lpszDeviceClass
parameter should be "tapi/phone", "", or NULL to cause the
provider to display the highest level configuration for the phone.
