KillaX Posted February 7, 2008 Share Posted February 7, 2008 _GDIPlus_GraphicsDrawLine ($hGraphic, 10, 150, $Gui_X, $Gui_Y, $hPen) I snagged the code from the help tutorial, as it's my first time using a GDI. I need to constantly update the coords of the 2nd point (gui_x and y). But I cant just keep reloading that command in a loop, as given time, ill have a solid black area. how can i constantly get new cords, without having to create over 500+ lines!
