  • Hello,


    The IME must be TSF-aware in order to be able to run in Windows 8 Consumer Preview. Windows 8 Consumer Preview blocks non-TSF-aware IMEs from running in Metro style apps. When an app is started, TSF loads the IME .dll for the IME that the user has selected into the application process.


    Note  To provide separate functionality or UIs between Metro style apps and desktop apps, the .dll loaded by TSF can check which type of app it is being loaded into. The IME calls the ITfThreadMgrEx::GetActiveFlags method and checks the TF_TMF_IMMERSIVEMODE flag, and can trigger different application logic depending on the result.
