This in VB6?

Hello,

This is a snippit from a VBScript routine.

Dim PINPad
Dim ResultString

Set PINPad = WScript.CreateObject("OPOS.PINPad")

WScript.ConnectObject PINPad, "EventHandler_"

The ConnectObject is my trouble. How would I do that in VB6?

Thanks

At a guess you would declare PINPad "With Events".

You would then create an event handler routine for each event you're
interested in.
Consult the API documentation for exposed events.

hi Ninefofo,

Tim Williams is right. The "WithEvents" declaration goes along
with referencing the object's typelib in your (vb) project.

Then vb can use the typelib to set up any event handlers that
you want.

But then, if you are going to reference the typelib, you may as
well just use "early-binding" rather than "late-binding" (i.e.,
just forget about CreateObject).

Scripting is different from vb in that all objects are "late-
bound" (except for the intrinsic built-in objects). And so
you have the WScript.CreateObject that includes connecting
to events, or ConnectObject for those situations where you
are getting access to an object some other way.

While you would be well advised to follow Tim Williams advice
and use "WithEvents", there is a way to connect events in vb
_WITHOUT_ access to the typelib.

It involves examining the ole interface (from code, of course),
and winds up doing the same thing as scripting's ConnectObject,
except in a different way.

If you want to check it out (for extreme techies only), read
Carlo Randone's: "COM: Handle Late-bound Events within Visual
Basic Using an ATL Bridge" (with code), found here:

The exposed events are documented in the link included in my reply.

Thanks. If I ever need to provide programming support for
MagTek devices, I'll know where to go...
