IInputMethod2::RegisterCallback2 (Windows CE 5.0)
This method is implemented to receive a pointer to an IIMCallback2 interface. An input method (IM) uses IIMCallback2 to send keystrokes to applications and to change the icons on the Input Panel button.
HRESULT RegisterCallback2(IIMCallback2* pIMCallback2);
Parameters
- pIMCallback2
Pointer to an IIMCallback2 interface implemented in the software-based input panel. The IM can call methods on this interface to send information back to the software-based input panel.

Return S_OK to indicate success. Return the appropriate HRESULT value to indicate failure.
Remarks
The IIMCallback2 interface to the software-based input panel is exposed only through this method. The software-based input panel calls this method during the initialization of the IM, along with Select, GetInfo, and ReceiveSipInfo.
