Hi All,

I am drawing some continus jpeg picture to screen, but the screen is
flashing, not like a video ....

I mean sometimes I can see some white area in the screen not all the
jpeg picture..., it seems the speed is very fast, become flash...

Best regards,
Boki.

PeekMessage( &msg, NULL, 0, 0, PM_NOREMOVE);

while (msg.message!=WM_QUIT) {

if (PeekMessage( &msg, NULL, 0, 0, PM_REMOVE)) {
   // dispatch the message
   TranslateMessage(&msg);
   DispatchMessage(&msg);
}
else
{
if (idle_load_jpg==1)
{
idle_load_jpg=0;
LoadPictureFileI(UART_Read_Stream(4097,ImageBfr));

                ////////////////// should I add it here ?
InvalidateRect(ghWnd, NULL, TRUE);

idle_load_jpg=1;
}
}

}

You have to wait for screen refresh. I was doing the same thing once and
had the same problem. Unfortunately, I lost the code so can't give you any
examples.
