*REFRESH
Post by Ric on Apr 24^th, 2016, 9:00pm

I have come across a severe flicker problem in my 3d imagery. It would appear that "InvalidateRect" does not refresh the screen but only the DIB section update. Does anyone know how to *REFRESH from assembler, possibly using CALL "oscli" ?

Yours hoping
Ric

Found the answer.

SYS "UpdateWindow", @hwnd%
Or

Push hwnd%
Call "UpdateWindow"

Works beautifully and flicker free.
