Hi all,

I am working inside a thread that drives a LCD screen and a camera. I
have to synchronize the display on the LCD and the camera acquisition. I
would like to know if there is any window message that is sent when a
window has been repainted (a sort of WM_ENDPAINT). I do call the Repaint
method of TWinControl but most of the time, the camera acquires a mix of
the previous frame and the new one. How can I be sure the LCD has been
fully repainted ?

Many thanks in advance.

Christophe
