DRV_CONFIGURE

Directs the installable driver to display its configuration dialog box and let the user specify new settings for the given installable driver instance.

Parameters

dwDriverId

Identifier of the installable driver. This is the same value previously returned by the driver from the DRV_OPEN message.

hdrvr

Handle of the installable driver instance.

lParam1

Handle of the parent window. This window is used as the parent window for the configuration dialog box.

lParam2

Address of a DRVCONFIGINFO structure or NULL. If the structure is given, it contains the names of the registry key and value associated with the driver.

Return Value

Returns one of these values:

DRVCNF_OK	The configuration is successful; no further action is required.
DRVCNF_CANCEL	The user canceled the dialog box; no further action is required.
DRVCNF_RESTART	The configuration is successful, but the changes do not take effect until the system is restarted.

Remarks

Some installable drivers append configuration information to the value assigned to the registry value associated with the driver.

The DRV_CANCEL, DRV_OK, and DRV_RESTART return values are obsolete; they have been replaced by DRVCNF_CANCEL, DRVCNF_OK, and DRVCNF_RESTART, respectively.
