Paint-method of TPW 1.5

Hello!

I've defined a timer-event (every 500 ms). Now I want to have my window
repainted every time my timer-procedure is called. I tried to call directly the
paint-procedure of the window, but it didn't work because I had to get the
PaintDC manually (and GetDC does only give it for the client-range). I've got
scrollers in the window, so what I need is a "global" PaintDC. I've also tried
to use

  SendMessage(HWindow,wm_paint,0,0)

but that didn't work either. Who know how I can have the window repainted
without call the paint-procedure manually ?

Thank's for your help!
