My application has to simulate keystrokes to another application.

If the destination window is the foreground window, I can send the 
messages using keybd_event(). Then I have no problem, even when I have 
to simulate a Shift key depressed : for instance, to simulate Shift+G, I 
call keybd_event() 4 times : Shift down, G down, G up and Shift up.
That's fine.

If the destination window is NOT the foreground window, I have to use 
something else. I tried SendMessage() (I have a handle to the 
destination window), and found that the destination application ignores 
the Shifts.
I had the opportunity to hook WindowProc in the destination application, 
so as to monitor the keyboard messages WM_KEYDOWN, WM_KEYUP and WM_CHAR.
I noted the sequence I got hooked when I actually typed the Shift+G 
sequence (WM_KEYDOWN Shift, WM_KEYDOWN G, WM_CHAR G, WM_KEYUP G and 
WM_KEYUP Shift) and repeated it in my program (verbatim, including scan 
codes, etc.). I found exactly the same sequence in the hook procedure, 
but unfortunatly, the destination application still ignored the Shifts.

So, I must miss something, another message ?

Several questions regarding keyboard and mouse simulations are posted 
here, but I could not find the answer, up to now.
