TUISPI_phoneConfigDialog

The TUISPI_phoneConfigDialog function causes the provider of the specified phone device to display a modal dialog box as a child window of hwndOwner to allow the user to configure parameters related to the phone device.This function makes the TSPI_phoneConfigDialog function obsolete in version 2.0 and later (supported in version 1.4 and earlier).

Implementation is optional.

LONG TSPIAPI TUISPI_phoneConfigDialog(
  TUISPIDLLCALLBACK lpfnUIDLLCallback,  
  DWORD dwDeviceID,                     
  HWND hwndOwner,                       
  LPCWSTR lpszDeviceClass               
);
 

Parameters

lpfnUIDLLCallback

Pointer to a function the UI DLL can call to communicate with the service provider DLL to obtain information needed to display the dialog box and to send updated configuration to the service provider.

dwDeviceID

The phone device to be configured.

hwndOwner

A handle to a parent window in which the dialog box window is to be placed.

lpszDeviceClass

A pointer to a NULL-terminated string that identifies a device class name. This device class allows the caller to select a specific subscreen of configuration information applicable to that device class. If this parameter is NULL or an empty string, the highest level configuration dialog box is selected.

Return Values

Returns zero if the function succeeds, or an error number if an error occurs. Possible return values are as follows:

PHONEERR_BADDEVICEID, PHONEERR_NOMEM, PHONEERR_INUSE, PHONEERR_OPERATIONFAILED, PHONEERR_INVALPARAM, PHONEERR_OPERATIONUNAVAIL, PHONEERR_INVALDEVICECLASS, PHONEERR_RESOURCEUNAVAIL.

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 TSPI_phoneGetID.

For example, if the phone supports the Comm API, passing comm/datamodem as lpszDeviceClass causes the provider to display the parameters related specifically to Comm (or, at least, to start at the corresponding point in a multilevel configuration dialog box chain, so that the user doesn't have to search to find the desired parameters). The szDeviceClass parameter should be "tapi/phone", "", or NULL to cause the provider to display the highest level configuration for the phone.
