Get handle of my scanner

FYI There is a link to the MSDN about a function  called EnumerateWiaDevices but this may be incorrect and I may need some help using this in Delphi
http://msdn.microsoft.com/en-us/library/ms629852(VS.85).aspx

There's also a Windows type library that enumerates image devices, but I'm still trying to figure out how to get a handle:
http://www.delphigroups.info/2/3/936314.html
==================================
I have imported
"Microsoft Windows Image Acquisition 1.01 Type Library"
using the Project / Import Type Library menu option. The file
WIALib_TLB.pas was created automatically.
I can get a list of cameras attached to my PC by doing:
procedure TForm1.FormCreate(Sender: TObject);
var
I: Integer;
Dev: IWiaDeviceInfo;
begin
wia.Connect;
Caption := IntToStr(wia.Devices.Count);
lb.Items.Clear;
for I := 0 to wia.Devices.Count - 1 do
begin
Dev := wia.Devices.Item[I] as IWiaDeviceInfo;
lb.Items.Add(Dev.Name + ' (' + Dev.Id + ')');
end;
end;

You can see from the functions I listed in the question stuff like open scanner, see if its available, scan an image, etc

Then you would notice that there is nothing in the documentation stating a 'handle' is available.
'Handle' is a generic term not a specification. Check the documentation for the ActiveX control you installed or contact the developer that created the ActiveX control.
Or you could always use the Microsoft API for free.

"Or you could always use the Microsoft API for free."
You mean Windows Image Acquisition (WIA)?
Unfortunately I couldn't find much in the way of example source code for Delphi - in fact I've spent a great deal of time trying to get the snippets of code that I *did* find to work.

"Check the documentation for the ActiveX control you installed or contact the developer that created the ActiveX control."
Yeah, unfortunately Fujitsu are dragging their feet on this - I have to pay to use their SDK but on their Japanese website they say it's free - AND the SDK comes with the scanner anyway -- well just the ActiveX library.
Here's an image:

Upload the generated TLB file (FiScnLib_tlb.pas) and I'll take a look;

Gave up

too bad :(   I don't think you needed the and with the the component dropped on the form you should have been able to do a;
FiScn1.Scan;
or
FiScn1.Start;
or something like that.

Could have been determined by looking at the FiScnLib_tlb.pas I asked for; or sending the OCX to me;
 

meant to say;
 don't think you needed the handle with the the component dropped on the form .
