=sinister= Posted June 8, 2008 Share Posted June 8, 2008 Is there any way to double buffer this? Func drawpix($dc,$x,$y,$color) $dll = DllOpen("user32.dll") $dc= DllCall ("user32.dll", "int", "GetDC", "hwnd", "") DllCall ("gdi32.dll", "long", "SetPixel", "long", $dc[0], "long", $x, "long", $y, "long", $color) DllCall ("user32.dll", "int", "ReleaseDC", "hwnd", 0, "int", $dc[0]) Link to comment Share on other sites More sharing options...
Moderators SmOke_N Posted June 8, 2008 Moderators Share Posted June 8, 2008 What are you talking about? Common sense plays a role in the basics of understanding AutoIt... If you're lacking in that, do us all a favor, and step away from the computer. Link to comment Share on other sites More sharing options...

martin Posted June 8, 2008 Share Posted June 8, 2008 (edited) Sorry I should explain more. The script above sets a cerain pixel a certain color. Double buffering helps reduce flicker http://en.wikipedia.org/wiki/Double_bufferingDouble buffering the change of a single pixel is not going to do anything more than waste some time. Is the problem that you are changing a lot of pixels and you get some flickering? For double buffering you need to change the pixels in a memory DC, then when all the pixels have been drawn copy the memory DC to the Gui DC. Or, stop Windows updating the gui, change all the pixels then allow the window to be redrawn. SendMessage( $Gui, $WM_SETREDRAW,0,0);stop redrawing ;change the pixels SendMessage( $Gui, $WM_SETREDRAW,1,0);allow redrawing DllCall("user32.dll", "int", "InvalidateRect", "hwnd", $GUI "int", 0, "int", 1);force a redraw If the pixels are changed on a control in the gui then instead of $gui you can use the handle for the control.
