autoit 輸入過程中切換輸入法

在測試客戶端的過程中有時需要切換輸入法 ，網上給的不是很嚴謹會報錯，究竟如何寫呢?

這樣寫（不要跨行）：

$hWnd = WinGetHandle("[ACTIVE]");$hWnd 爲目標窗口句柄，這裏設置的是當前活動窗口
$ret = DllCall("user32.dll", "long", "LoadKeyboardLayout", "str", "08040804", "int", 1 + 0)
DllCall("user32.dll", "ptr", "SendMessage", "hwnd", $hWnd, "int", 0x50, "int", 1, "int", $ret[0])        
Send("you text")
