  • Article

4/8/2010

Implement RegisterCallbackEx to receive a pointer to an IIMCallbackEx interface. An input method (IM) uses the IIMCallbackEx interface to send keystrokes to an application and to change the icon on the InputPanel button.

Syntax

HRESULT RegisterCallbackEx (
  IIMCallback* pIMCallback 
);

Parameters

  • pIMCallback
    Pointer to an IIMCallbackEx interface implemented in the input panel. The IM calls methods on this interface to send information back to the input panel.

Return Value

An appropriate HRESULT value is returned.

Remarks

The IIMCallbackEx interface to the input panel is exposed only through this method. The input panel calls this method during the initialization of the IM, along with Select, GetInfo, and ReceiveSipInfo.

Requirements

Header sip.h
Windows Embedded CE Windows CE 3.0 and later
Windows Mobile Pocket PC 2000 and later
