guinness Posted July 19, 2014 Author Share Posted July 19, 2014 A better approach would be to hide the global variable around function calls. So now the user only has to interact with the functions and not the global variable. expandcollapse popup#include <GUIConstantsEx.au3> #include <WinAPI.au3> #include <WindowsConstants.au3> Global Enum $GUI_ACTION_LCLIENT, $GUI_ACTION_RCLIENT, $GUI_ACTION_LTITLE ; An enumeration of possible actions.
