HRESULT SendCharEvents( UINT uVK, UINT uKeyFlags, UINT uChars, UINT* puShift, UINT* puChars );
Virtual key code sent in the first WM_KEYUP or WM_KEYDOWN message generated as a result of this method.
Unsigned integer that contains flags describing the state of the first key sent by this method. These flags are translated into the lKeyData parameter of the first message. See Keybd.h for the legally defined values. If the KeyStateDownFlag bit is set, this method generates a WM_KEYDOWN message; otherwise, it generates a WM_KEYUP message.
Number of characters in puChars.
Pointer to a buffer containing the corresponding KEY_STATE_FLAGS for the characters in puChars. See Keybd.h for the legally defined values. These flags should be identical to the flags in uKeyFlags.
Pointer to a buffer containing the all characters but the first one sent by this method.
This method allows the IM to determine its own keyboard layout, because it can associate any virtual key with any character and key state.
Unlike IIMCallback::SendVirtualKey, this method does not affect the global key state.
