Harro, I am trying to poll Skype for events, I want something to happen when it is minimised. I have found some code on the forum that almost works, I have been tweaking it, but just can't get the minimise event to work. I would love some help on this. as I am not amamzing at DLL calling and such... the event handle for $EVENT_SYSTEM_MINIMIZEEND is never hit.. even when i minimise the window, i always get the same event codes. Here is what I have so far... #include <WindowsConstants.au3> #include <WinAPI.au3> #include <Process.au3> #include <Misc.au3> Global $hDLL, $hWinEventProc, $hHook HotKeySet("{ESC}", "_HotKey") ; Exit ;Event Constants Global Const $EVENT_SYSTEM_SOUND = 0x0001 ;An MSAA event indicating that a sound was played.
