This function causes the provider of the specified phone device to display a modal dialog box (attached to the application's hwndOwnerparameter) that allows the user to configure parameters related to the phone device specified by the dwDeviceIDparameter.

Syntax 

LONG WINAPI phoneConfigDialog(
  DWORD 
dwDeviceID,
  HWND 
hwndOwner,
  LPCSTR 
lpszDeviceClass 
);

Parameters

dwDeviceID

Phone device to be configured.

hwndOwner

Handle to a window to which the dialog box is to be attached. Can be a NULL value to indicate that any window created during the function should have no owner window.

lpszDeviceClass

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 Value

Returns zero if the request succeeds or a negative error number if an error occurs. The following table shows the return values for this function.

Value Description

PHONEERR_BADDEVICEID

The device identifier is incorrect.

PHONEERR_NOMEM

Not enough memory is available.

PHONEERR_INUSE

The phone device is in use.

PHONEERR_OPERATIONFAILED

The operation failed.

PHONEERR_INVALPARAM

The parameter is invalid.

PHONEERR_OPERATIONUNAVAIL

The operation is unavailable.

PHONEERR_INVALDEVICECLASS

The device class is invalid.

PHONEERR_RESOURCEUNAVAIL

The resources are unavailable.

PHONEERR_INVALPOINTER

The pointer is invalid.

PHONEERR_UNINITIALIZED

A parameter is uninitialized.

PHONEERR_NODEVICE

The device was not found.

Remarks

The lpszDeviceClassparameter 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 lpszDeviceClasswould 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 box chain, eliminating the need to search for relevant parameters).

The lpszDeviceClassparameter should be "tapi/phone", "", or NULL to cause the provider to display the highest level configuration for the phone.

Note:
This function is for TAPI version 2.0 and later.

Requirements

Header tapi.h
Library coredll.lib
Windows Embedded CE Windows CE 3.0 and later
