Hello Nine,Glad to see that you added double buffering to this UDF,I tried many UDFs to creat a png button,all of them cause flickering except your UDF.
But,there's something I still don‘t understand. What's wrong with this countdown gif, It is overlapping.
Global $IMG_Ctrl1 = _GUICtrlCreateAnimGIF("1.gif", 150, 50, 285, 280, -1, $GUI_WS_EX_PARENTDRAG, False, 0 )
I tried to change the $nBackColor to 0,it works.But if there is a backgroud picture ,It is overlapping again.
