3.1.3.Acquiring the Status Using BiSetStatusBackWnd
If you are acquiring auto status notification by a
language which does not support callback
functions like Microsoft Visual Basic 5.0 32-bit
with Office Service Pack 3, use
BiSetStatusBackWnd. If this function is used and
the addresses of the memory where the printer
status are stored and the window handle of the
buttons on the application’s screen, the Status
API sets the new status in the specified addresses,
and sends a click event to the registered buttons.
For details of how to use this method, please refer
to the Visual Basic 5.0 32-bit with Office Service
Pack 3sample program which is included in the
package.
