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.
