Determining the Composition String (Windows CE 5.0)
To determine the composition string and generate the result string, the IME UI calls the IImeIPoint2::ControlIME method with the IPCTRL_DETERMINALL function identifier. The IME UI calls the IImeIPoint2::UpdateContext method to prompt the conversion service to send back the result string through the IImeIPointNotifySink callback function. The IME UI usually sends the result string to the application.
To clear all composition buffers and to prepare the conversion engine for new user input, the IME UI calls the IImeIPoint2::ControlIME method with the IPCTRL_CLEARALL function identifier.
