lineConfigDialog
The lineConfigDialog function causes the provider of the specified line device to display a dialog
(attached to hwndOwner of the application) to allow the user to configure parameters related to the
line device.
LONG lineConfigDialog(
DWORD dwDeviceID,
|
| HWND hwndOwner,
|
| LPCSTR lpszDeviceClass
|
| );
|
|
Parameters
dwDeviceID
The line device to be configured.
hwndOwner
A handle to a window to which the dialog is to be attached. Can be NULL 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:
LINEERR_BADDEVICEID, LINEERR_NOMEM, LINEERR_INUSE, LINEERR_OPERATIONFAILED,
LINEERR_INVALDEVICECLASS, LINEERR_RESOURCEUNAVAIL, LINEERR_INVALPARAM,
LINEERR_UNINITIALIZED, LINEERR_INVALPOINTER, LINEERR_OPERATIONUNAVAIL, LINEERR_NODEVICE.
Remarks
The lineConfigDialog function causes the service provider to display a modal dialog (attached to hwndOwner of the application) to allow the user to configure parameters related to the
line specified by dwDeviceID. 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 lineGetID. For example, if the line supports the Comm API, passing "COMM" as lpszDeviceClass causes the provider to display the parameters related specifically to Comm
(or, at least, start at the corresponding point in a multilevel configuration
dialog chain, so the user doesn't have to "dig" to find the parameters of
interest).
The lpszDeviceClass parameter would be "tapi/line" , "", or NULL to cause the provider to display
the highest level configuration for the line.
