post message from App to Internet Explorer

[Mo]

Hi all,
i am writing an App that reads from a barcode scanner.
i want to find a way to send the barcode to an open window (such as
Internet Explorer) so that when the user scans the barcode, the result
is displayed in any text box the user clicked. (the user has to click
on that text box --set focus-- before he triggers the barcode scanner)
i was looking into PostMessage(HWND_BROADCAST,WM_KEYDOWN,barocde,0).
but wasn't working.
i also tried PostMessage(GetForegroundWindow(),WM_KEYDOWN,barocde,0).
but wasn't working either.
my APP is a console app, no output statements (so a windows is not
created)

Any idea?
the window name is non constant so i cannot use
FindWindow( LPCTSTR lpClassName, LPCTSTR lpWindowName );

Your help is greatly appreciated

Thanks
Mo

Windows programming questions should be asked in a Windows programming
group, such as You are off topic
here since this group is about the C++ language.

OFF TOPIC

Nonetheless:

Make a window of yours the active window. When the user
clicks the other window, your window should receive a
message WM_LOSTFOCUS or something like that. With any luck
I believe it also gives you the HWND of the new window
that's in focus.

SetWindowText(hWnd,"sjfas;ljf");
