ImmGenerateMessage (Windows CE 5.0)

Send Feedback

This function enables an input method editor (IME) to generate messages that are sent to the window associated with the input method context (IMC). These messages are stored in the hMsgBuf member of the INPUTCONTEXT structure identified by the hIMC parameter.

BOOL WINAPI ImmGenerateMessage( HIMC hIMC);


  • hIMC
    [in] Handle to the INPUTCONTEXT structure that contains IME messages in its hMsgBuf member.

Return Values

TRUE indicates success. FALSE indicates failure.


This is a general purpose function, but it is typically called by an IME when the input method manager (IMM) calls the ImmNotifyIME function to notify an IME of a context update.

An IME user interface (UI) should not call this function only to update UI appearance. Instead, the IME UI should be updated when the IME is informed about an updated IMC. It is recommended that this function be used by an IME only when the IME changes the IMC without any keystroke activity from the user and needs to inform an application of the change.
