WMP / FFDshow "flip"   

hi,

i wrote, with Xbase++, activex Player with WMP.
as Codec is use FFDshow.

sometimes i got "upside-down" Video so i use
FFDshow "flip" Option. FFDshow also have
a "remote Keyboard" Option so i can use "Crtl-Alt-F"
for "flip"

now i try to simulate "Crtl-Alt-F" from my activex WMPlayer.
*** snip ***
FUNCTION KEYSENDF
   // Tasten drücken
   keybd_event(VK_CONTROL,0,0,0)
   keybd_event(VK_MENU,0,0,0)
   keybd_event(ASC("F"),0,0,0)

   // Tasten wieder loslassen
   keybd_event(ASC("F"),0,KEYEVENTF_KEYUP,0)
   keybd_event(VK_MENU,0,KEYEVENTF_KEYUP,0)
   keybd_event(VK_CONTROL,0,KEYEVENTF_KEYUP,0)
RETURN NIL

FUNCTION keybd_event(nVk,nScan,nFlags,nExtraInfo)
STATIC keybd_event
   IF keybd_event = NIL
      keybd_event := DllPrepareCall("user32.dll",DLL_STDCALL,"keybd_event")
   ENDIF
RETURN DllExecuteCall(keybd_event,nVk,nScan,nFlags,nExtraInfo)


.or.


FUNCTION FF_FLIP()
LOCAL cStr := ""

   cStr := cGenKeyboardInput(VK_CONTROL)
   cStr += cGenKeyboardInput(VK_MENU)
   cStr += cGenKeyboardInput(ASC("F"))

   cStr += cGenKeyboardInput(ASC("F")  ,,KEYEVENTF_KEYUP)
   cStr += cGenKeyboardInput(VK_MENU   ,,KEYEVENTF_KEYUP)
   cStr += cGenKeyboardInput(VK_CONTROL,,KEYEVENTF_KEYUP)

   SendInput(cStr)
...

FUNCTION cGenKeyboardInput(vk,scan,flags,time,extra)
   DEFAULT vk := 0
   DEFAULT scan := 0
   DEFAULT flags := 0
   DEFAULT time := 0
   DEFAULT extra := 0
RETURN 
PADR(U2Bin(1)+W2Bin(vk)+W2Bin(scan)+U2Bin(flags)+U2Bin(time)+U2Bin(extra),28,CHR(0))

FUNCTION SendInput(cInput)
RETURN DllCall("user32",32,"SendInput",INT(LEN(cInput) / 28),cInput,28)
*** eof ***

but both do not work ? it does work from a small Demo without WMP
so im asking what can be the reason with activex WMP that "Crtl-Alt-F"
will not pass to FFDshow, any Idee ?
