> In the meantime, put "typename" in front of the declaration.
Yesn I put, but now i get this error
../../ZipCollections.h: In member function `BOOL CZipMap<KEY, 
   VALUE>::Lookup(KEY, VALUE&) const':
../../ZipCollections.h:148: parse error before `;' token
../../ZipCollections.h: In member function `BOOL CZipMap<KEY, 
   VALUE>::Lookup(KEY, VALUE&) const [with KEY =
CZipArchive::CallbackType, 
   VALUE = CZipActionCallback*]':
../../ZipArchive.h:1770:   instantiated from here
../../ZipCollections.h:149: `iter' undeclared (first use this function)
../../ZipCollections.h:149: (Each undeclared identifier is reported only
once 
   for each function it appears in.)

Reading map from Gcc c++ include files the const_iterator is defined
their as an typename

What i`m doing wrong
My .h file bellow (the part where error apear
template<class KEY, class VALUE>
class ZIP_API CZipMap : private std::map<KEY, VALUE>
{
public:
	void SetAt( KEY key, VALUE newValue)
	{
		insert(std::map<KEY, VALUE>::value_type(key, newValue));
	}
	BOOL RemoveKey( KEY key )
	{
		return erase(key) != 0;
	}
	BOOL Lookup( KEY key, VALUE& rValue ) const
	{
          	typename const_iterator iter ;
		iter =  find(key);
		if (iter == end())
				return FALSE;
		else
		{
			rValue = iter->second;
			return TRUE;
		}
	}
};
