class dependencies and namespace

[Mosfet]

Hi,

I am trying to solve an issue with a dependency between two classes as
shown below :



atlwince.h (declaration and definition is done in the .h)
----------



struct _ATL_AYGSHELL_STATE
{
public:
// Handle initialization and cleanup of AYGSHELL
_ATL_AYGSHELL_STATE()
{
if (!AYGSHELL::SHSipInfo(...)) <- Not yet defined
{
m_nAygshellUIModel = Smartphone;
}
else
{
m_nAygshellUIModel = PocketPC;
}
}
};

const _ATL_AYGSHELL_STATE& ATL_CDECL _AtlGetAygshellState();
BOOL WINAPI AtlIsAygshellSupported();
int WINAPI AtlGetAygshellUIModel();
BOOL WINAPI AtlIsDRAEnabled();
void WINAPI AtlEnableDRA(BOOL bEnable);





namespace AYGSHELL
{
inline BOOL SHSipInfo(UINT uiAction, UINT uiParam, PVOID pvParam, UINT
fWinIni)
{
const _ATL_AYGSHELL_STATE& aygshellState = _AtlGetAygshellState();
ASSERT(aygshellState.m_pfnSHSipInfo);

return aygshellState.m_pfnSHSipInfo(uiAction, uiParam, pvParam, fWinIni);
}


}// namespace AYGSHELL

As you can see I have a mutual dependency bewteen these two classes.
When I compile I get :

error C2653: 'AYGSHELL' : is not a class or namespace name

Just forward declare AYGSHELL::SHSipInfo before the declaration of
struct _ATL_AYGSHELL_STATE

namespace AYGSHELL
{
inline BOOL SHSipInfo(UINT uiAction, UINT uiParam, PVOID
pvParam, UINT fWinIni);
}

Thanks and regards

Also, change your names. _ATL_AYGSHELL_STATE is a reserved identifier.
Identifiers with a leading underscore followed by an uppercase letter
are reserved to the implementation in all scopes.
