Creates a list of registered window classes that support Active Input Method Managers (IMMs).
HRESULT FilterClientWindows( [in] ATOM *aaClassList, [in] UINT uSize );
The address of a list of window classes.
An unsigned integer that contains the number of window classes in the list.
Returns S_OK if successful, or an error value otherwise.
When the user shifts focus, the window receiving focus is checked. If the window is on the list, then all of the Active Input Method Editors (IME)s are available. If it isn't on the list, the Active Input Method Editors (IMEs) are shut down. This enables the application to work safely with Common Controls and other components that are not Active IMM-aware.
