Handling IME Window Messages (Windows CE 5.0)
The system sends IME window messages to the window that has focus when certain events occur. For example, the system sends the WM_IME_SETCONTEXT message when a window is activated. IME-unaware windows pass these messages to the DefWindowProc function, which sends them to the corresponding default IME window. IME-aware windows either process these messages or forward them to their own IME windows.
To have an IME window carry out an action, use the WM_IME_CONTROL message. To have the IME notify an application about changes to the composition string, use the WM_IME_COMPOSITION message. Use the WM_IME_NOTIFY message for general changes to the status of IME windows.
To process the WM_IME_COMPOSITION message, applications test the bits in the lParam parameter and call the ImmGetCompositionString function to retrieve the indicated string or data.
