sDLLName = StrCat(DirWindows(1), "user32.dll")
DLLCall(sDLLName, long:"GetKeyboardState", lpbinary:buf)
BinaryEodSet(buf, 256)
return buf
#endfunction
boxopen("","Press any key.")
buf1 = binaryalloc(256)
before = GetKeyboardState(buf1)
buf2=binaryalloc(256)
while 1
after = GetKeyboardState(buf2)
if BinaryCompare(before, 0, after, 0, 256)==@false then break
endwhile
binaryfree(buf2)
