Hi,

I got compilation error: c:\gms\Services\DeviceManager\VCUE_Copy.h(134): warning C4346: 'MapType::value_type' : dependent name is not a type

for the following codes:

template <class MapType, class DestinationType = MapType::referent_type>
    class MapCopy
    {
    public :
    --->> typedef MapType::value_type    source_type;

any suggestion? I am using VS.NET C++7.0
thanks

typedef typename MapType::value_type source_type;

Within a template definition, if a qualified name that depends on a
template parameter is supposed to refer to a type, the name must be
preceded by the keyword "typename".
