[Setacl-devel] COM and SetACL

[Howard W W. <hwo...@ms...>]

>> COM control: Howard, would you like to start with the
control?

sure

>> When I started to work on the main class CSetACL I
implemented the interface to the outside world first - it
should be complete enough by now to be able to build a
control (and a console EXE) around it. My plan was to expose
the public funtions in the control which are all input
functions to pass data to the class. There is, of course,
the need to pass strings back to the calling
class/function/EXE, like detailed error/success/status
messages which might be needed by the caller. I used a
callback function for that purpose to be able to send any
message in realtime while the program is still working.
Example: someone uses the OCX to build a GUI around SetACL.
The user of this GUI wants to create a permission listing of
a large partition which might take a while. Via the callback
function the GUI can display in real time the permissions
that currently processed by SetACL. Is a callback function a
viable way to do it and does it work with COM?

Hum ho.

(1) where are the current classes there are no files to download on the
site.
Are we working from a clean sheet ?
(2) what kind(s) of COM objects do you want to implement. It is not possible
to have one ATL COM object which will run as a console app, a COM server and
as an ActiveX control, though of course there are common elements.
It looks to me that the wish list consist of
a. a classic ATL COM application that does pretty much the same as the
current setACL
b. a COM server that can be called from any C++ application; a version that
supports VB6 is a little different cos of the wacky VB6 strings
c. a console version of (a)
d. an OCX control for scripters / VB6

My suggestion is to implement (a) amd (c) first. (b) can be derived from
that fairly easily. (d) is a different bag of tricks - an ActiveX OCX
control runs in the thread of the app that invokes it remember, and VB6
cannot do free threading except by black arts. Getting back to the COM
object generally with COM u define the interfaces and methods and then build
a UI to express them rather than developinf downwards from the UI VisualC++
wizard style. Do u have the resource files for the dialogs anyway ?
It would help a lot if u can post the souce for the original SetACL so i can
get my head aorund your thinking, plus anything for the new one u have apart
from specs. which I have.

If an ActiveX control for VB6/vbscript were available, it would help to
 server is other additional applications, i.e. ASP-based web applications
and
 VBA.
