[WIN] stuffing keyboard buffer

Hi, all.	

Several people responded to my request on how to stuff the keyboard buffer, so
that a program would 'think' a certain
key had been pressed.

Tone.Skoda suggested the following:

sendMessage(WM_KEY,WM_KEYDOWN,key,lParam)
sendMessage(WM_KEY,WM_KEYUP,key,lParam)    

That presents two new problems (both the result of my own ignorance about how
Win32lib works). What needs to go in
'key', and what should go into 'lParam'? I have reviewed the doco for Win32lib,
but these two parameters are not
discussed (that I can find). I did find the definition of sendMessage, which is
as follows:
     
global function sendMessage( integer id, atom cmd, atom wParm, atom lParm )

but that still didn't tell me what should go into these two parameters.

I found the following in the definition for IsHotKey()

if event = WM_SYSKEYDOWN and key = VK_F10 then
        VOID = sendMessage(id, WM_KEYDOWN, key, lParam)

In this case, the contents of key are: VK_F10     
leading me to think that perhaps the parameter 'key' can contain VK_I
to send the upper case letter 'I', or VK_F to send the uppercase letter 'F',
(the keystrokes I'm trying to emulate), but
I'm really just guessing.

If anyone has had experience with the 'sendMessage' command and can help me with
the correct contents of these two
parameters, I would appreciate your help.

Thanks.
