CWnd::get_accValue 

Called by the framework to retrieve the value of the specified object.


virtual HRESULT get_accValue(
   VARIANT varChild,
   BSTR *pszValue
);

Parameters

varChild

Specifies whether the value information to be retrieved is that of the object or one of the object's child elements. This parameter can be either CHILDID_SELF (to obtain information about the object) or a child ID (to obtain information about the object's child element).

pszValue

Address of the BSTR that receives a localized string containing the object's current value.

Returns S_OK on success, a COM error code on failure. See Return Values in IAccessible::get_accValue in the Platform SDK.

This function is part of MFC's Active Accessibility support.

Override this function in your CWnd-derived class if you have nonwindowed user interface elements (other than windowless ActiveX controls, which MFC handles).

For more information, see IAccessible::get_accValue in the Platform SDK.
