IDocHostShowUI::ShowHelp

HRESULT STDMETHODCALLTYPE ShowHelp( 
    HWND hwnd,
    LPOLESTR pszHelpFile,
    UINT uCommand,
    DWORD dwData,
    POINT ptMouse,
    IDispatch *pDispatchObjectHit
);

Called by IE4/MSHTML when it needs to show Help.

hwnd
Handle to the owner window.
pszHelpFile
Help file name.
uCommand
Type of Help. See the WinHelp function.
dwData
Additional data. See the WinHelp function.
ptMouse
Mouse position in screen coordinates.
pDispatchObjectHit
IDispatch of the object at the screen coordinates.

The first four parameters are the same as those passed to the WinHelp function. The ptMouse parameter gives the screen coordinates, and the pDispatchObjectHit parameter allows the host to differentiate the object at the screen coordinates to a greater degree than IE4/MSHTML.
